        <p>Energetic music has the potential to enhance immersion but can also negatively impact task performance. This study measured the efects of music on a video game suited for energetic music using both subjective (questionnaires) and objective (facial and physiological analysis) measures. Participants played under two conditions: with and without music. While the music condition led to higher reports of immersion, no significant diference between the two conditions was found. Performance scores were better without music, suggesting that energetic music, while increasing immersion, may disrupt performance by intensifying the task. These findings emphasize the importance of aligning immersion with task relevance, as the efects of music on performance are context-dependent. Further investigation into the balance between engagement, task perception, and performance is needed.</p>

      <title>1. Introduction</title>
      <p>
        Music has been shown to have a significant negative efect on cognitive performance,
especially on high-intensity tasks [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ]. However, energetic music has been also shown to increase
immersion, particularly in video games [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ]. This challenges preconceived notions that higher
immersion is directly related to higher performance and warrants further investigation into the
exact relationship between music as a positive factor for immersion, yet a potential negative
factor for performance.
      </p>
      <p>
        A study by [
        <xref ref-type="bibr" rid="ref3">3</xref>
        ] suggests that music familiarity might play a role on how daunting a given
task is perceived, which the researchers attributed to higher stress levels and as a result, the
performance of the task. In detail, they found that music, specifically selected by the participant,
had mostly a positive efect on task performance. Conversely, task performance was lower when
the participant was exposed to unfamiliar, high-arousal music chosen by the experimenter.
      </p>
      <p>
        Another study [
        <xref ref-type="bibr" rid="ref4">4</xref>
        ] found that a slow-tempo song afected cognitive processing speed
negatively, as opposed to a higher-tempo song, which increased cognitive processing speed. These
seemingly contradictory conclusions suggest a nuanced relationship between music and task
performance.
      </p>
      <p>Given these findings, this study aims to explore the efect of energetic music on task
immersion and perception while playing a vertically scrolling video game or vertical scroller type
of a video game1. Specifically, we will investigate how varying levels of immersion impact
task performance, and if higher immersion is indeed related to higher task performance. By
understanding these dynamics, the research seeks to clarify the relationship between music,
immersion, and cognitive performance in this specific context of a vertical scroller video game.</p>
      <p>We have formulated the following research questions to guide our study:
RQ1 “How does energetic music during gameplay of a scrolling dodge video game afect the level
of immersion experienced by the players?”,
RQ2 “How does energetic music during gameplay afect game perception (workload, pace, arousal)? ”
and
RQ3 “How does game immersion and perception afect overall task performance? ”
To address these research questions, the study aims to achieve the following objectives:
• Develop a vertical scroller video game designed to measure player immersion under
diferent music conditions.
• Conduct a user study involving participants who will play the game with and without
music.
• Collect data on player immersion and performance using a combination of questionnaires,
eye tracking, facial expression, skin conductivity, and game scores.
• Evaluate the impact of energetic music on immersion, and how immersion is related to
overall task performance.</p>

      <sec id="sec-2-1">
        <title>2.1. Music and Gameplay Performance</title>
        <p>
          The relationship between video game immersion and music is already well documented. It is
known that music and sound efects play a large role in video game immersion, but studies into
this topic show inconclusive objective results, suggesting a more nuanced relationship between
the music provided in the video game and video game immersion. One study [
          <xref ref-type="bibr" rid="ref2">2</xref>
          ] found that
participants reported a higher level of immersion when playing a high intensity, fast paced
video game, which included music and/or sound efects compared to the same video game
without music and sound efects. Interestingly, the only statistically significant results were
from subjective measures, such as the Game Experience Questionnaire (GEQ), while objective
measures, including psychophysiological recordings of electrodermal activity (EDA) and facial
muscle activity (EMG), did not yield significant results.
1Vertically scrolling video game https://en.wikipedia.org/wiki/Vertically_scrolling_video_game
        </p>
        <p>This lack of objective conclusion presents an opportunity for this study to utilize objective
measures of immersion, such as pupil size, electrodermal activity, in order to find a more
objective determiner of immersion.</p>
      </sec>
      <sec id="sec-2-2">
        <title>2.2. Music and Cognitive Performance</title>
        <p>
          Research has already extensively documented the efects of music on cognitive performance,
showing varied results based on the type of music and task. One study [
          <xref ref-type="bibr" rid="ref5">5</xref>
          ] found that background
music can impair performance on complex cognitive tasks, especially those that require memory
and comprehension. On the other hand, other research [
          <xref ref-type="bibr" rid="ref6">6</xref>
          ] found that calming music had a
positive impact on cognitive tasks, followed by no music, and finally energetic, high-intensity
music, which had a negative efect. Another study [
          <xref ref-type="bibr" rid="ref7">7</xref>
          ] found that music had a positive efect on
cognitive performance, but only when referring to simple, repetitive tasks.
        </p>
        <p>
          Interestingly, one article [
          <xref ref-type="bibr" rid="ref8">8</xref>
          ] suggested that the relationship between music and cognitive
performance is more complex and dynamic than just observing music afects on immersion. It
suggests that the impact of music on immersion and performance depends on various external
factors.
        </p>
      </sec>
      <sec id="sec-2-3">
        <title>2.3. Impact of Music on Task Perception</title>
        <p>
          Several studies [
          <xref ref-type="bibr" rid="ref1 ref3">1, 3</xref>
          ] noted that unfamiliar, high-intensity music increased stress levels,
suggesting that energetic music might induce a sense of panic, pressure and a need to perform,
which directly afect how a task is perceived. While other studies [
          <xref ref-type="bibr" rid="ref9">9</xref>
          ] found that calm music
lowered anxiety levels in participants. While these studies produced significant findings, it is
worthwhile to discuss the aspect of compatibility of music with a given task. For instance, in
one study [
          <xref ref-type="bibr" rid="ref1">1</xref>
          ], fast-paced music was played while assessing reading comprehension, raising
questions about the appropriateness of the music for the given task.
        </p>
        <p>Consequently, our study aims to address the issue of musical compatibility and nuance by
creating an environment where highly energetic music is appropriately matched to the task
intensity, such as in a vertical scroller video game. In this type of game the player views the
action from a top-down perspective, with the background scrolling from the top to the bottom
of the screen, setting a rhythm for gameplay, and requiring the player to respond rapidly to the
scrolling environment. By selecting music that aligns with the nature of the task, we tried to
ensure that the music enhanced rather than detracted from the task experience. As a result, to
efectively explore the impact of music on task perception and performance, we have developed
a video game specifically for this user study. This game, serves as the experimental environment
for our study.</p>
      </sec>

    <sec id="sec-3">
      <title>3. Design and Implementation of the Video Game</title>
      <p>The game developed for this user study is titled Dance Dance Mania, a Dance Dance Revolution
inspired vertical scrolling and timing-based game designed with a colorful 8-bit retro aesthetic
to maintain player engagement. We developed our own game to avoid the familiarity with the
existing games which could benefit some uswers, and to better control the game exectution
(same scenario, the increasing of the pace, time of the game run, etc.). With existing games this
was not possible and too many other variables would be introduced.</p>
      <p>In the game developped players need to press the correct arrow keys in sync with arrows
falling down the screen when these overlap with the gray arrows on the bottom of the screen as
shown in Figure 1. The game starts slowly, with arrows taking 4.5 seconds to reach the bottom
and appearing every 2 seconds, allowing players to adjust. As the game progresses, the speed
increases, with arrows moving 6 times faster (0.75 seconds to the bottom) and generated at 2
arrows per second, creating a more challenging experience within the 120-second (2 minutes)
round.</p>
      <p>The scoring system is simple: a “Perfect” hit (correct timing of pressing the arrow key when
the falling arrow completely overlaps with the gray arrow) adds 2 points to the score, a “Good”
(slightly mistimed pressing of the arrow key when the falling arrow slightly overlaps with the
gray arrow) adds 1 point, while a “Wrong” key press or a “Missed” arrow deducts 1 point. At
the end of each round, the player’s score and performance details (number of Perfects, Goods,
Wrongs, and Misses) are displayed. Both the game’s music and sound efects follow the retro
theme, creating a cohesive audiovisual experience.</p>
      <p>A pre-determined sequence of arrow generation ensures all participants face the same
dificulty level. Participants play four rounds of the game, experiencing either music in the first and
third rounds or the second and fourth rounds, based on their assigned starting condition.</p>

      <title>4. Methodology</title>
      <sec id="sec-4-1">
        <title>4.1. User Study Design</title>
        <p>Participants were recruited through university boards and word-of-mouth. A total of 10
participants, aged between 20 and 23, signed up for the study. There was no criteria for participant
selection, and no incentives were ofered for participation. All participants were university
students. They were informed that the study involved playing a video game under difering
conditions, but information regarding the study’s expectations, hypothesis, and research questions
was not disclosed.</p>
        <p>The study was conducted in a controlled environment to minimize external variables. The
setup involved the use of iMotions software to collect facial expressions, eye tracking data, and
galvanic skin response together with heartbeat. Participants were randomly assigned to one of
two conditions, while ensuring that each had an equal number of participants.</p>
      </sec>
      <sec id="sec-4-2">
        <title>4.2. Procedure</title>
        <p>Upon arrival, participants were briefed on the study’s procedure. They were then asked to sign
informed consent forms, which explained their rights, the voluntary nature of their participation,
and the confidentiality of their data.</p>
        <p>Next, the experimenter showcased a 10 second demo of the game, to help participants
understand the controls, the mechanics, and what diferent sound efects refer to. This demonstration
did not involve the use of music. Following that, the experimenter explained diferent hardware
that would be used to monitor the participants immersion level. The Shimmer 3 GSR Unit was
applied to the participant’s non-dominant hand to avoid interference with gameplay controls.</p>
        <p>Next, participants played four rounds of Dance Dance Mania each lasting 2 minutes. In one
condition the participants experienced music and sound efects in the first and third round
of the game and only sound efects in the second and fourth round. In the other condition
participants experienced music and sound efects in the second and fourth round of the game
and only sound efects in the first and third round. After the second round, participants were
given a brief break to relax.</p>
        <p>We opted for four rounds of the game to make sure the participants got familiar with the
game during the first two rounds and knew what to expect in the music condition and no-music
condition. We then only took the results of the third and fourth round. This ensured that the
majority of the learning happened during the first two rounds and the learning efect is smallest
between round 3 and 4. Following the third round, participants completed the NASA-TLX and
the Immersive Experience Questionnaire (IEQ), documenting their experience specific to that
round. After the fourth round, they completed the same questionnaires, this time focusing on
their experience in the final round. Finally, participants filled out a custom-made questionnaire
about their music and gaming history, as well as demographic information including age and
gender. At the end of the study, the participant’s game scores were saved and labeled accordingly.
For a quick summary of the study procedure, refer to Table 1.</p>

          4.3.1. Questionnaires
The questionnaires completed after round 3 and round 4 are the aforementioned NASA-TLX
task (work)load index2 and the Immersive Experience Questionnaire (IEQ) developed by [
          <xref ref-type="bibr" rid="ref10">10</xref>
          ].
NASA-TLX is a widely recognized subjective, multidimensional assessment tool used to evaluate
perceived workload, allowing for the assessment of a task, system and other performance-related
factors.
        </p>
        <p>The IEQ was slightly changed by omitting questions not pertinent to this particular game,
such as questions about in-game events and story. Most questions were rated on a 7-point
Likert scale, while others required participants to select discrete answers such as “Yes”, “No”, or
“Maybe”.</p>
        <p>The questionnaire related to the participants’ music and game history included items designed
to identify potential outliers and provide a foundation for future research.</p>

        <title>4.4. Measuring Physiological Response</title>
        <p>
          In order to measure Physiological response, the following iMotions products were used:
• Afectiva AFFDEX [
          <xref ref-type="bibr" rid="ref11">11</xref>
          ] - utilizing a Logitec webcam to capture facial expressions at 720p.
        </p>
        <p>For each timestamp, Afectiva provides a set of facial expression and a value ranging from
0 to 100 for each facial expression (a higher value means that particular emotion is more
expressed or noticeable), For some emotions that can be either negative or positive (i.e
Valence), a value ranging from -100 to 100 is provided instead (less than 0 means negative
valence, more than 0 means positive valence)
2NASA-TLX https://en.wikipedia.org/wiki/NASA-TLX
• Tobii Pro Spectrum screen for eye tracking purposes. At each timestamp, we are provided
with multiple values related to eye movement. For the purpose of this study, we will use
pupil size parameter.
• a Shimmer 3 GSR Unit attached to the participants non-dominant hand. The Shimmer
measures electrodermal reactions and heart rate. The main electrodermal reaction used
in this study is GSR Conductance, which reflects changes in skin conductance related to
physiological arousal.</p>
      </sec>
      <sec id="sec-4-5">
        <title>4.5. Game Scores</title>
        <p>For each participant, data was collected for the number of “Perfects”, “Goods”, “Misses”, and
“Wrongs” within each round of gameplay, as well as the final score for that round. Additionally,
the round number and whether or not the round included music were recorded.</p>

      <title>5. Data Analysis Methods</title>
      <sec id="sec-5-1">
        <title>5.1. Analysing Video Game Immersiveness</title>
        <p>
          NASA-TLX was score was derived using a weighted sum of the participants’ responses, with the
weights provided by a manual on how to calculate NASA-TLX scores [
          <xref ref-type="bibr" rid="ref12">12</xref>
          ]. For IEQ negatively
scored items (i.e., items indicating a lack of immersion) were inverted (e.g., a score of 1 becomes
7, a score of 2 becomes 6, etc.), and then the responses were summed. The method used for
calculating the results from the questionnaires is based on practices in previous research [
          <xref ref-type="bibr" rid="ref13">13</xref>
          ].
        </p>
        <p>We will utilize the following metrics provided by the aforementioned iMotions tools:
• Engagement: Reflects the level of involvement with the task.
• Valence: Indicates the positive or negative emotional tone.
• Attention: Measures how attentively a participant is focused.
• Brow Furrow: Associated with concentration or confusion.
• Eye Widen: Often a sign of surprise or heightened attention.
• Lip Press: Can indicate stress or concentration.
• Lip Suck: May be a sign of nervousness or deep thought.
• Mouth Open: Could signal surprise or high arousal.</p>
        <p>• Smile: Reflects positive engagement or enjoyment.</p>
        <p>Higher values in these metrics generally suggest greater immersion.</p>
        <p>TA larger pupil size captured by Tobii Pro Spectrum eye tracker is typically associated with
higher levels of arousal, which, in the context of our study, correlates with increased immersion.
Elevated skin conductance and heart rate captured by Shimmer 3 GSR Unit are also often
associated with higher levels of arousal, which may indicate increased either immersion or
nervousness in the task.</p>
        <p>To efectively utilize these values in our data analysis, we used the mean of each measurement
across the entire duration of each round. By averaging these values, we can provide a clearer
comparison of emotion levels both between participants and across diferent conditions, such
as rounds with music and rounds without music.</p>
        <p>As by the study procedure described in subsection 4.2 we used a within-subject design. The
influence of music on task performance is measured in the same way as immersion. Prior to data
analysis, Shapiro-Wilk tests and Q-Q plots will be used to determine whether the diferent results
follow a normal distribution across all participants. If a given immersion or performance result
follows a normal distribution, we will use a paired t-test. On the other hand, if a performance
and immersion result does not follow normal distribution, we will use a Wilcoxon test.</p>

        <p>For the within-subject design, NASA-TLX workload scores and IEQ immersion scores were
compared between the same participants, for rounds 3 and 4. The mean NASA-TLX score when
participants experienced music condition was slightly higher ( = 979,  = 367.1) compared to
when they experienced no-music condition ( = 976,  = 313.7). Despite this small diference,
the paired t-test results ((9) = 0.088,  = 0.9312  = 0.008) showed no significant diference
in the NASA-TLX score between the two conditions. Conversely, the mean Immersion score
when participants experienced music condition was larger ( = 50.8,  = 7.6) compared to
participants who experienced no-music condition ( = 45.8,  = 6.8). The paired t-test results
((9) = 1.811,  = 0.10  = 0.691) suggested a marginally significant diference between the
two conditions, with a large efect size.</p>

        <p>Prior to data analysis, Shapiro-Wilk tests and Q-Q plots confirmed a normal distribution of the
aggregated data captured by iMotions. We observed no discernible diferences in the mean values
of emotions between the two conditions. While some emotions exhibited higher mean values
under the music condition, others showed higher mean values under the no-music condition.
Utilizing paired t-tests, we found no significant diferences between the two conditions for
any of the analyzed emotions, additionally, the efect sizes were very small. The most notable
result was observed for the “Lip Press” expression. Here, the mean value for the expression
when participants were exposed to music condition was slightly higher ( = 4.27,  = 7.46)
compared to when they were exposed to no-music condition ( = 2.65,  = 4.61). The paired
t-test yielded: (9) = 1.72,  = 0.12, Cohen’s efect size  = 0.08. Even then, the efect size is
minimal. For detailed statistical results of all emotions refer, to Table 2</p>

        <p>Prior to data analysis, Shapiro-Wilk tests and Q-Q plots confirmed a normal distribution
of the aggregated data. A within-subject design was used to analyze gameplay performance
between the two conditions: As mentioned, in order to minimize the learning curve efect, we
opted to only use rounds 3 and 4. We will now refer to rounds 3 and 4 as such: the rounds
where people experienced music as the music condition and the rounds where people did not
experience music as the no-music condition.</p>
        <p>• Score: The mean scores in the music condition was actually lower ( = 248.5,  = 54.05)
than in the no-music condition ( = 256.4,  = 48.7). Despite this, the paired t-test
results ((9) = − 0.94,  = 0.37, Cohen’s efect size  = 0.20) showed no significant
diference between the scores.
• The number of “Goods”: the mean amount of “Goods” was actually higher in the music
condition ( = 46.8,  = 19.42) compared to no-music condition ( = 39.3,  = 14.06).
The paired t-tests showed a borderline significant diference between the two conditions,
and a small to medium efect size ( (9) = 1.78,  = 0.10, Cohen’s efect size  = 0.45).
• The number of “Perfects”: The mean amount was smaller in the music condition ( =
110.9,  = 24.50) compared to the no-music condition ( = 119.1,  = 21.24). The
paired t-test results showed no significant diference ( (9) = − 1.72,  = 0.12, Cohen’s
efect size  = 0.35.

        <title>7.1. Result Interpretation</title>
        <p>Even though the mean NASA-TLX workload score was slightly higher in music condition, the
diference in workload scores was statistically insignificant, and the efect size was negligible.
Thus, it is reasonable to assume that music has no efect on the perceived workload. On the
other hand, the mean values of the immersion scores were notably higher in music condition.
Despite the non-significant diference, the lower p-value and larger efect size suggest that music
might enhance the immersive experience of the game. With that in mind, there is a possibility
that a Type II error occurred (i.e a false negative) due to the small sample size, indicating that
the study might not have had suficient power to detect a significant diference.</p>
        <p>When analyzing the physiological data, the diferent emotions that would indicate immersion,
did not follow a discernible trend or pattern. Engagement, attention, valence, and smile counts
were higher in the no-music condition, while the number of joy expressions, lip presses, and
brow furrows were higher in the music condition. Due to the non-significant diferences and
small efect sizes, it can be assumed that music either has no significant efect on immersion or
that the participants did not express immersion through facial expressions.</p>
        <p>Additionally, the higher GSR conductance in the music condition, although insignificant,
might indicate heightened emotional responses such as fear, excitement, anxiety, or stress. This
supports the idea that energetic music, especially unfamiliar music, might increase nervousness.
This could either indicate heightened immersion levels or a break in immersion. Based on
self-reported immersion scores, GSR conductance could be a supporting factor for music’s
impact on immersion.</p>
        <p>The game scores were higher in no-music condition, and while these diferences are also
non-significant, The fact that 9 out of 10 participants played better when there was no music
involved, as well as obtained the smaller amount of “Misses”, and “Wrongs” and the larger
amount of “Perfects” strongly supports the idea that music, especially unfamiliar music is
distracting and can lead to more errors, even if it matches the taks at hand. There is also a
possibility that a Type II error occurred in the significance testing, due to the small amount of
participants.</p>

        <title>7.2. Addressing Reseach Questions</title>
        <p>Research question 1: How does energetic music afect the level of immersion experienced by the
player
• The diference in immersion scores in the self reported immersion questionnaires, as
well as the diference in GSR conductance, is a strong indicator that music positively
influences the level of immersion experienced by the player.</p>
        <p>Research question 2: How does energetic music during gameplay afect game perception (workload,
pace, arousal)?
• Due to the conflicting results, namely, the NASA-TLX workload score yielding no
significant diference, supporting the idea that energetic music has little to no efect on game
perception, while the GSR Conductivity indicated higher levels of arousal, which could
mean that the participants were more stressed, anxious, or in panic due to the game being
perceived as faster, or more dificult, we cannot come to a definite answer. In a subsequent
questionnaire, participants were asked if the music changed their perception of the pace
or intensity of the game, to which 7 answered that the pace of the game felt faster, 2
answered that the pace of the game felt slower, while 1 answered that it felt the same.
While this result does not provide statistical significance, it does provide insight into the
relation between energetic music and task perception, but further research is needed.
Research question 3: How does immersion and game perception afect game performance?
• While it is clear that the presence of music negatively impacted game performance,
the exact reasoning behind this efect can be explored in various ways. One possible
interpretation is that participants perceived the game as more dificult or fast-paced when
music was present, leading to a higher propensity for mistakes. This notion is slightly
supported by the findings related to the second research question. A third interpretation
is that participants did indeed experience higher immersion levels, but this immersion
was related more to the overall game experience rather than the specific gameplay itself.
The presence of music might have led participants to feel that they should enjoy the
game fully, rather than focus on performing the task to the best of their abilities. This
suggests that music might have influenced their emotional engagement with the game
environment rather than their cognitive engagement with the gameplay mechanics. The
emotional engagement, driven by energetic music, could have made the participants
feel more connected to the game setting, yet distracted them from optimal gameplay
performance. Additionally, energetic music is often described as distracting, thus leading
to a divided attention scenario. Participants might have found themselves paying more
attention to the music, which created an immersive auditory environment, but at the
expense of their concentration on the game’s mechanics and objectives.</p>

      <sec id="sec-7-3">
        <title>7.3. Comparison with Previous Studies</title>
        <p>
          Our findings closely align with some of the previous studies. Namely, research suggesting that
music negatively impacts game performance, and that energetic, unfamiliar music is seen as
distracting [
          <xref ref-type="bibr" rid="ref1 ref3">1, 3</xref>
          ]. Concurrently, our finding align with previous research concluding that there
is no significant diference in performance between no-music condition and music condition [
          <xref ref-type="bibr" rid="ref4">4</xref>
          ].
        </p>
        <p>
          Our findings also align with research suggesting that music helps with the immersive
experience [
          <xref ref-type="bibr" rid="ref2">2</xref>
          ]. The discrepancy between higher immersion and lower performance observed in this
study can be better understood through previous research. Previous studies have established a
significant correlation between immersion and performance [ 14, 15, 16], but this relationship
depends on the immersion being directly relevant to the task at hand. In our study, the high
levels of immersion were induced by intense, high-tempo music. This form of immersion was
maybe not directly related to the gameplay task, leading to the observed lack of improvement
in performance [
          <xref ref-type="bibr" rid="ref10">10, 17, 18, 19</xref>
          ]. Moreover, the energetic nature of the music likely introduced
additional stress and nervousness for participants.
        </p>
        <p>Thus, it appears that immersion only supports task performance when it is closely tied to the
task itself. In cases where the immersive element, such as high-tempo music, is not task-related,
it may not contribute positively to performance and can even hinder it.</p>
        <p>Additionally, task immersion is shown to be most impactful to performance when the task
relies heavily on working memory, spatial reasoning, and the ability to mentally manipulate
and store information (e.g trying to memorize a pattern, or an image) [14, 15]. Moreover, studies
have shown that immersion is least significant when the task performed is highly reliant on
motor skills, reaction time and the ability to synchronize physical movements with visual
inputs [16], such as the video game in our study.</p>
      </sec>
      <sec id="sec-7-4">
        <title>7.4. Implications of Findings</title>
        <p>First, the results suggest that simply increasing immersion through elements like high-tempo
music does not inherently enhance performance. Instead, the efectiveness of immersion is
highly context-dependent. So, designers of immersive experiences should be mindful of how
immersion elements relate to the specific task.</p>
        <p>Second, the impact of diferent types of music on task performance empathizes the need
for careful selection of audio stimuli. While calming music has been shown to improve
performance, energetic and intense music might increase stress levels and lower eficiency. This
information can guide the selection of background music in various settings, including
workplaces, educational environments, and therapeutic settings, to optimize user experience and
performance.</p>
        <p>Regarding stress management, the negative impact of high-tempo music on performance
underlines the importance of managing stress in immersive environments. Designers should be
aware of how immersive elements, such as music, afect stress levels and overall well-being.
providing options for users to select their preferred auditory environment could mitigate
potential negative efects.</p>
        <p>In practice, understanding that immersion must be relevant to the task can improve the
design of virtual environments and other immersive applications. By coordinating immersive
elements with the specific goals of the task, practitioners can create more efective and engaging
environments that enhance user performance and satisfaction.</p>

      <sec id="sec-7-5">
        <title>7.5. Limitations of Study</title>
        <p>There were a few limitations of the study. The most impactful limitation is the small sample size.
This likely hindered statistical power, increasing the risk of Type II errors, and incorporated a
large amount of participant variability, which could be a confounding variable. This additional
variability might have influenced the results, making it dificult to isolate the efects of music.
An additional limitation would be the hardware used. During the user study, the Shimmer unit
failed to detect a heart rate, resulting in the heart rate values being unusable, which would have
otherwise been a useful statistic. The study focuses on a single type of game and one specific
type of music (energetic, high-tempo). While this focus allows for controlled testing, it limits
the generalizability of the findings to other game genres or music types. Future research could
include diferent genres of music or diferent types of games (e.g., strategy, puzzle, adventure
games).</p>

      <title>8. Conclusion</title>
      <p>This study aimed to analyze the impact of energetic music on game immersion, game perception
and performance. and whether there is a reasonable connection between them. We collected
a combination of subjective questionnaires (NASA-TLX, IEQ) and objective measures (eye
tracking, skin conductivity, facial expressions) as indicators of immersion. Additionally, the
efect of music on game performance was assessed through in-game scores. The statistical
analysis found no statistically significant diferences in mean values for most emotional and
physiological measures between the music and no-music conditions. Additionally, the analysis
found no statistically significant diferences in game scores. Despite this lack of statistical
significance, several key observations emerged: the mean values of immersion in the immersion
questionnaire were higher in the music condition than in the no-music condition. This suggests
that participants felt more immersed when music was present. However, this increased sense of
immersion did not translate into improved performance, as the no-music condition had higher
performance scores on average.</p>
      <p>These findings lead to a deeper examination of the relationship between immersion and
performance. The observed discrepancy, where increased immersion was associated with lower
performance, suggests that the energetic music might have been detrimental to performance.
This prompted a hypothesis that immersion, to positively impact performance, needs to be
directly related to the task at hand. Previous research supports the notion that immersion can
enhance performance when it is closely aligned with task requirements. In contrast, when the
immersive element, such as high-tempo music, is not relevant to the task, it may not contribute
positively and could even impair performance.</p>
      <p>The relationship between immersion, perception and performance needs to be further
investigated by exploring how diferent types of immersion, particularly those tailored to align
with the nature of the task, influence performance. Studies could investigate various immersive
elements and their direct relevance to specific tasks to better understand how immersion can be
optimized for diferent activities. For instance, examining how task-specific immersion afects
performance could reveal more about the conditions under which immersion enhances task
outcomes.</p>
      <p>Exploring individual diferences, such as personal music preferences, baseline stress levels,
or familiarity with the task, could ofer insights into why some individuals experience varying
efects compared to others. Expanding research to include diferent contexts beyond video
games, such as educational environments, workplaces, or therapeutic settings, would help
understand how immersive elements like music impact performance in a variety of real-world
scenarios.</p>
