      <title>1. Introduction</title>
      <p>The brain-computer interface (BCI) makes it possible to optimize one's activities through the
development of cognitive skills. Today, neuroplasticity training methods are becoming more and more
popular, and monitoring the mental well-being of employees is becoming a real policy of many
companies. The spectrum</p>
      <p>of application of BCI covers the fields of assistive technologies,
entertainment, in particular environments with immersive components, the fashion industry, the Internet
of the new generation, and education. When making decisions, a person is faced with the influence of
cognitive biases. Minimizing the degree of influence of such factors makes it possible to optimize
working processes and increase cognitive interaction efficiency. To achieve this goal, special strategies
are created, which are implemented in smart environments equipped with the BCI module.</p>
      <p>The introduction of special training in the education of students or the internship of employees
(decision-makers) is carried out in conditions of decision-making close to professional ones when the
decision is made exactly during the duration of a normal response time based on the regular study. The
strategy embodies at the same time the planning of professional development or academic success and
at the same time tracking the well-being of research participants.</p>
      <p>The wide development of BCI at the intersection of many trends in information technology forces
us to evaluate the next steps in the development of technology and outline the likely directions and
solutions for wide implementations. It is also worth noting the new challenges and problems of using</p>

such technologies in the predicted conditions. The greatest interest lies in the fascination of the next
2030 years, and the conditions are influenced by the progress of development technologies and approaches
to system design. No less important factors will be the co-alignment in the labor market of different
generations and the difference in the ability to use such tools [1;2].</p>
      <p>One of the most important achievements of BCI in modern society is the successful suppression of
several age-related health disorders (dementia, Alzheimer's disease), disability, schizophrenia,
Asperger's syndrome, increased activity syndrome, and attention deficit disorder in children. BCI's
achievements in this direction, combined with special practices, are already improving lives, providing
opportunities for the full functioning and socialization of millions of people [3;4]. New waves and
spheres of interest of BCI have applied studies of consciousness (consumerism, elections,
neuroaesthetics), training (success, pleasure), and health surveillance (fitness, yoga, sleep, well-being).
The study of the nature of choice and free will in the application to the testing of applied systems
increases the efficiency of business and training strategies and develops the functionality of social
research and methods of organizing network work and enterprises, improving the quality of products.</p>

      <title>2. State of the problem</title>
      <p>Judging and decision-making are the main components of most social activity and important factors
for system efficiency development. These concepts connected with reason and intelligence so carefully
investigated and implemented last decades. The basis of the modern state of we can find in a lot of
scientists. In 1906 Charles Spearman proposed a g factor for the evaluation of intelligence. His ideas
were developed in general intelligence testing in most educational systems. In 1936 Kurt Levin
proposed the field theory of social activity. The main point of this approach today is widely used in
human-computer interaction, especially the well-known agent-environment paradigm in smart
technologies [5]. The scientist described the general rule of activity as:</p>
      <p>
        B = f(P, E),
(
        <xref ref-type="bibr" rid="ref1">1</xref>
        )
where B is behavior represented as a function of P (person) and E (environment).
      </p>
      <p>According the last researches, the view of cognition can be represented in some complex form.[35]
external conditions and influencing on reality and environment through body and equipment with
constant improving of experience and own abilities.[36]</p>
      <p>Any changing of reality and environment can be represented as stimulus or problem for mind, which
has own solving (right type of influence, decision) and time for it. Besides, brain has two functional
parts (primal brain and cortex2), which compete decision-making and thus some answers on stimuli can
be fast, but no-right, or right, but not in time etc. This is biased part of problem.[26; 27]</p>
      <p>In everyday activity human meet a problem of cognitive biases. Cognitive biases are deviations from
wished, logical or right decisions and clear judgements. In general scientists classified 127 separate
such biases. Between them are well-known presque vu, overconfidence bias, bias of false attribution,
correlation of similar objects, pareidolia, framing, anchoring etc. Most previous researches investigate
a few typical cognitive biases. The real state of the problem, that approach for . Improving self-control
on different conditions is valuable opportunity since neuroplasticity training strategies become popular.
Today there are most widespread in systems with brain-computer interface for workload monitoring.</p>
      <p>The newest evolutionary abilities of technologies in intelligence development tend to improve
human opportunities in influence on reality and matter. Between them consciousness imitation and
upload, which can be implemented on consciousness agents.

      <title>Related Works</title>
      <p>Research by Ceschi A. (2018) aims to develop an anti-biased statistical approach as a decision
support system for group decision-making (GDM) to detect and handle bias. The paper suggests that
these biases conform to a model composed of three dimensions: Mindware gaps, Valuation biases (i.e.,
Positive Illusions and Negativity effect), Anchoring, and Adjustment. Scientists develop an anti-biased
statistical approach, including extreme, moderate, and soft versions, as a decision support system.
Between methods, the multiple component analysis and independent component analysis are used for
the investigation of participants' problem-solving with previous heuristics and biases studies. Results
prove that exploratory and confirmatory analyses yielded a solution that suggested that these biases
conform to a described model [6].</p>
      <p>This approach and data can be used for similar fields of research and experience design, especially
in educational systems. Free will and consciousness interaction in the decision-making process is an
important question in neuromanagement and cognitive science. Authors are reviewing a growing
argument for unconscious effects on decision-making, which intuitively challenge free will.</p>
      <p>Researchers (Mudrik L. 2022) suggest that unconscious influences on behaviour affect degrees of
control (reasons-responsiveness). Basic arguments proclaim that there is no certain evidence of the
existence of free will in general, but only the degree to which we can be free in specific circumstances.</p>
      <p>The unconsciousness influences and awareness in the decision-making process are investigated
through samples of routine stimuli on employee subjects within the session designed with special
situations conditions features. The approach includes critical reviews of result precision in uncertain
conditions and focused on decision-related neural activity preceding volitional actions as the subject of
investigation [7]. These results can be used by developers for new systems improvements in ergonomic
workspace design as by employees for decision-making process optimization and well-being
monitoring. Upon general approaches which determine the theory of decision-making with the purpose
for practical use and real implementation of this knowledge, careful attention must be paid to Nick
Bostrom's Superintelligence and Russel's Artificial Intelligence. The first work is a very important block
for the development of logical prognosis skills and forming of the view of today's situation in
intelligence evolution. The second is a successful description of today's state of things in artificial
intelligence. This work is actual for each part of our research.</p>
      <p>Separately, according to the priorities of this review interests and further development, we should
emphasize so important works such as On Intelligence (2004) by Jeff Hawkins. The main value of this
work is that it helps to clarify the difference between human and machine thinking. Used investigation
of the neocortex creates successful modeling of neural activity and describes structural functions of the
mind [8]. The ethical issues violated in these works are connected with the required legislation of
technologies and implementation of approaches into the work process.
2 The third on is neocortex. It influences on higher abilities of human mind as wisdom.</p>
      <p>William Benzon devotes a separate paragraph to elementary regularities of the cognitive process. It
means that simple cognition is a copy of activity in the sensorimotor system located in the temporal
lobe of the cerebral cortex. Each node in simple cognition is defined by a sensorimotor scheme. The
connecting arcs between the nodes reflect the nature of the feedback interaction between the circuits
represented by the nodes at each end of the communication arc. Simple cognition is organized into a
musical structure that reflects the number of details in basic schemas, a compositional structure that
reflects the volume of schemas, and a syntagmatic structure that reflects the organization of
sensorimotor orders.</p>
      <p>Computer modeling of processing in a simple cognitive example is a paradigmatic, syntagmatic, and
component structure - quite complex. William Benzon emphasizes the rapid development of computer
modeling, but notes with disappointment that "computational understanding of system abstraction is
but a gleam in the eyes of a very few." The digital computers of the 1970s had a problem. The
architecture of the processors of the time was sequential, only one calculation could be performed at a
time, while the operation of the abstraction system required parallelism, the ability to perform a large
number of calculations simultaneously.</p>
      <p>Since nodes in an abstraction system cannot be named, it follows that we can only communicate
directly about rationalization. The recasting of rationalization into a real abstract definition involving
the functioning of the episodic abstraction system is internalization, as is the recasting of episodes into
systemic concepts. The intuitive part of any intelligent organization is likely to reflect the operation of
the abstraction system when using its abstract schemas. The hard work of giving verbal form to these
intuitions by constructing a statement of first-order abstract concepts is rationalization. Faculty
psychology is a rationalization of the activity of the nervous system. W. Benzon illustrates his research
with conceptual diagrams [9].</p>
      <p>In The way we think: conceptual blending and the mind's hidden complexities (2002) by Gilles
Fouconier and Mark Turner cognitive networks are presented as metaphorical patterns correlated with
the phenomena of human life in society through the study and presentation of hidden or implicit
constructions of the mind and the playing of possible situations. Researchers call this model conceptual
blending. To achieve quite an understanding of cognitive functionality scientists are using a grand
variety of tools proposed by its cross-scientific area and developed new approaches to investigate
absolutely new concepts. Upon them, cognitive architectures for creating frameworks, features of
cognitive processing and its imitation strategies, phenomena description (such as the hard problem of
consciousness), theory of Global Workspace, and cognitive augmentation must be mentioned [10].</p>
      <p>Analysis based on cascading cycles of recurring brain events caused by the structure of human
cognition is presented in Baars and Franklin's (2015) research. Each cognitive cycle senses the current
situation, interprets it regarding ongoing goals, and then selects an internal or external action in
response. While most aspects of the cognitive cycle are unconscious, each cycle also yields a
momentary "ignition" of conscious broadcasting. Stan Franklin and Bernard Baars used a model of
LIDA's cognitive cycle developed with a timing (an initial phase of perception (stimulus recognition),
80–100 ms, conscious episode (broadcast) 200–280 ms, and an action selection phase of 60–110 ms).
This model is closely connected with the brain indicating a theta-gamma wave, fixed as a stream from
sensory cortices to rostral corticothalamic regions. This wave may be experienced as a conscious
perceptual event starting at 200–280 ms post-stimulus. For action selection in the cycle is proposed to
use frontal, striatal, and cerebellar regions.</p>
      <p>As a result of research, there are two LIDA-based software agents are specified (based on Reaction
Time that simulates human performance in a simple task, and the Allport for modeling phenomenal
simultaneity within timeframes comparable to human subjects). Research can be implemented in
environments with cognitive architecture and approbation of its design [5].</p>
      <p>Regression analysis is one of the main approaches for data visualization in the most of researches.
Scientists tend to represent some new approach to correlation coefficient understanding and using.
Correlation coefficient is the main concept of the major cases for quick and accurate using in statistics.
In this research the approach of data analysis connection with theory of global workspace is proposed.
The paper (Rodgers J.L. and Nicewander W. A. 1988) presents 13 different formulas, each of which
emphasize on a different computational and conceptual definition of correlation coefficient. Each
formula suggests a different way of thinking about this index, from algebraic, geometric, and
trigonometric settings. The formulas are presented in a way that allows readers to see the connections
between them and to understand the underlying concepts that they represent. Results can be used in
data analysis especially in correlational analysis and critical skills development [6].</p>
      <p>The basis of neuromanagement can be found in Neuromanagement and leadership (Venturella I. et
all, 2018). This work describes EEG analysis of the mental activity in organization study according to
the newest tendencies of neuroscience analysis in cognitive sciences as well-being and workload
through typical human activity</p>
      <p>The last neuromanagement achievements are improved by BrainSigns and JLL. The first companies
established workload idea with EEG for state recognition technology.</p>
      <p>The brain-computer interface (BCI) makes it possible to optimize one's own activities through the
development of cognitive skills. Today, neuroplasticity training methods are becoming more and more
popular, and monitoring the mental well-being of employees is becoming a real policy of many
companies. The spectrum of application of BCI covers the fields of assistive technologies,
entertainment, in particular environments with immersive components, fashion industry, the Internet of
the new generation and education.</p>
      <p>Further development of brain-mediated network mode may concern not only more physical applied
networks, but the global and virtual also. The nearer question of technology implementation is how
such technology and approach can transform Internet use, especially in databases development and
knowledge exchange? Such mode improvised in virtual realities and global network can optimized
next development and will have positive influence for common wellbeing.</p>
      <p>Anton Nijholt in Competing and Collaborating Brains: Multi-Brain Computer Interfacing (2015)
describes the features of brain-computer interface applications that assume two or more users and at
least one of the users’ brain activities is used as input to the application. Scientist used the EEG
monitoring approach. Investigation was supported by real-time and off-line processing to analyze and
store large amounts of streaming data collected in experiences, which include gaming, entertainment,
immersion, and based on the study of control, robustness, and emotion monitoring.</p>
      <p>Scientists consider extensions of current applications by looking at different types of multi-user
games, including massively multi-player online role-playing games, distinguishing between active and
passive BCI on multi-participant BCI in non-game contexts. Research is focused on collaborative and
competitive multi-brain games. Important attention is paid to the state-of-the-arts concept in BCI
technology and psychological group analysis [12]. These paper results can be used for human-machine
interaction and ergonomics research and development in different systems.</p>
      <p>Internet of Things (IoT) and brain-computer interface (BCI) are modern emerging technologies. Its
combination is more popular last times. The central problems of such decision for user’s environments
and smart systems are methods of signal processing and sensors sensibility. Researchers (Laport F. at
all, 2018) propose to use electroencephalography (EEG) analysis as component of communication
interface for BCI implementation in IoT systems. As a model of signal translation the Message Queue
Telemetry Transport (MQTT) protocol is used. Proposed method experienced on special study with
FP2-channel within 3-day session of users activity and its results represented as α/β ratio of eye
movement. Further development of this results can be used for real implementation in Smart Houses
and development of applied design methods [13]. There are a lot of real implemented samples of
braincomputer interfaces today. A few projects should be named are: a system for car-drive and race (Emotiv
and SIMUSAFE), aviation (g.tec and BrainSigns), neuromarketing (Emotiv, BrainSigns, JLL), mental
health and self-care (Emotiv, g.tec, BitBrain, NeuroSky, BrainSigns) and advertisement (Emotiv,
NeuroSky, g.tec). All these companies have large experience in assistive technologies providing, but
they are the ones who inaugurated BCI users’ society.

      <title>Cognitive approach in human-computer interaction research</title>
      <p>Modelling of custom connectomes has already been implemented by EMOTIV in the BrainViz
program. However, there is a problem: cognitive biases as a "knowledge effect" have a rather large
influence on training and efficiency performance in regular use (preliminary results of the project
"Cognitive optimization system of a smart educational environment with BCI module").</p>
      <p>Ethics is also an important issue in development, covering a wide range of ergonomics requirements
and a number of regulations and statutory standards. From the mid-1990s to today, the issue of
legalization of BCI-society has been widely covered in projects and programs of the European Union
Commission, in particular Horizon 2020 and the Human Brain Project.</p>
      <p>Great attention to the issue of quality development of neuro-computer interfaces (NCI) is devoted
in such fundamental works as Fundamentals of BCI by A. Nijholt, Clocking the mind by Jensen A. R.,
Toward Brain-Computer Interfacing by Dornhege G.. An important research method is multi-level
analysis in system design [8;14].</p>

      <title>3. Session Design</title>
      <p>I used the method of evaluating mental activity in the process of decision-making in the conditions
of professional activity. The system includes a bank of typical tasks, a module for forming and
evaluating the test, BCI and a graphical interface. In addition, voice and tactile input can be provided.
In the process of solving tasks, data are collected: educational, mental, cognitive. Educational ones
include the type of task object (code, concept, value, set, graph, formula), correct answer option, error,
execution time. Primary mental metrics include raw encephalogram, secondary metrics include
cognitive metrics such as attention, cognitive stress, and engagement.</p>
      <p>Participants are invited to take a test with a set number of professionally oriented tasks within a set
time. The criteria for the professionalism of the environment are: the material of the tasks corresponds
to professional knowledge, the time to answer a question is equal to a normal response, limited duration
of the test according to the ergonomical recommendations (15 - 90 minutes). The research is carried out
at workstations with BCI. Collected data includes raw EEG, score of testing, and performance metrics
are expertly evaluated by criteria of efficiency (accuracy and reaction time) and workload (control and
biases).</p>

      <title>EMOTIV Toolbox for BCI research</title>
      <p>For this research I used EMOTIV Insight 2.0 device for EEG biofeedback recording and EMOTIV
Labs environment for training sessions and investigation. In this paper I focused attention on typical
task for neuroplasticity training and BCI literacy testing based on Stroop effect. These conditions is
absolutely satisfactory for cognitive biases investigation and evaluation.</p>
      <p>EmotivPRO and BrainViz are software for BCI research, which use all needed tools for mental
activity visualization (Figure 4). Above: normal performance. 20th sec of session. State: awake, flow,
good attention, normal engagement. Average Reaction Time 623 ms. Band Power for T8 sensor: Theta
– 5%, Beta - 4%, Gamma – 2%. Differences between frequencies powers 0,5-1% (calm mind, flow
state). Below: biased performance with mistake. 60th sec of performance.</p>
      <p>Cognitive bias: motivational. Increasing Theta band power (5%) on both Pz and T8 points shows
state of resting. May be caused by tiredness. On performance metrics (see below) we can find lost of
attention and engagement without increasing of cognitive stress [29]. After session all results are
automatically evaluated by comparison with participant age group. The main interest of research is
focused on Performance Metrics and training progress of participants.</p>
      <p>The opportunity to respond is available during the normal reaction time (RT, 2000-3000 ms). The
results are fixed and stored. After completing the test, the participant reviews the tasks a second time in
the same sequence and analyzes own answers. The participant indicates whether he answered correctly
and which answer is correct, or explains why he did not answer or did not have time to answer, and also
provides information about the specifics of decision-making. Ready 120s tests based on collected
previous analysis can be very useful. Based on these data, the type of cognitive bias and the degree of
its action can be determined by time and intensity indicators (duration of action in milliseconds and
change in indicators of involvement or concentration). Then the answers are compared, the complete
picture of the test is determined [25]</p>

      </p>
      <p>Biasing of performance has its own determination. It is the relation between four groups of biases
(Figure 9). For generalized representation biases can be collected in table.</p>
      <p>In this research, I used noninvasive portable electroencephalograph Emotiv Insight 2.0. This device
detects EEG on AF3, AF4, T7, T8, and Pz sensors. The methods of ERP recognition, independent
component analysis, and support vector machine are used for collecting biofeedback data as real-time
EEG and Performance Metrics, which help to investigate dynamics of such features of biofeedback as
affection, attention, tiredness, engagement, cognitive stress, rest, and exciting.</p>
      <p>First column represents the equipment and software used for sessions and data collecting. Second
is generalized process view with data description (where Acc. is for accuracy, RT – response time, PM
– performance metrics (attention, engagement, cognitive stress), PM2 – emotional performance metrics
(excitement, focus, relaxation). Questioner 1 is questions about subjective evaluation of current state.
Questioner 2 is subjective evaluation of own performance, which helps to fix overestimating of
confidence type of biases (motivational). ERP (event-related potentials) – technology used for
computation of RT and PM changes according to actions (key inputs). Convolutional neuronal networks
and Support Vector Machines are used in EMOTIV Labs for PM decoding from rawEEG inputs. P300
paradigm is used for ERP detection. Output data collected in .csv or .xls formats. Pavlovia framework
can be used for sharing results. PsychoPy environment is comfortable for professional sessions design.</p>
      <p>To investigate the effect of cognitive biases, an analysis of performance metrics is carried out with
the marking of points of influence and the evaluation of the degree of action. Marking is based on
participants answers. The degree of action is described by the duration and intensity of the factor. A
qualitative characteristic is a group of cognitive biases.</p>
      <p>For example, pareidolia belongs to the perception group, and framing belongs to memory biases.
The intensity of cognitive bias is defined as the ratio of the normal value of the characteristic indicator
(attention, involvement) to the factor affected by the action. For each session, I use additional testing
before the performance and after the session. These tests include evaluation of EEG, band power of
waves, brain activity, and emotional and performance metrics during 1,5 – 0,5 min. Also, I use
questionnaires for performance [33].</p>
      <p>The influence of cognitive biases can be evaluated by typical indexes of the session as reaction
time, accuracy, and performance metrics.

key connected with the meaning of the word and focuses on color.

        <p>We have the problem of the impossibility of ideal performance as an observation problem. Anybody
can't imitate an absolutely clean performance. My further research interest includes investigating this
phenomenon with imitated performance. Realization of this task foresees the development of a
cognitive environment with artificial consciousness or using the LIDA model.</p>

mindbody problem and brain entanglement it would be actual to use quantum cognition architectures for the
system design. To perform classification task for performance metrics evaluation in decision-making
process with biased states a variational quantum circuit with rotation operator gates and free parameters
can be used (Figure 10).</p>
        <p>In quantum computation | ⟩ =  |0⟩ +  |1⟩, ‖ ‖2 + ‖ ‖2 = 1 is a two-dimensional complex
vector normalized representation for a single qubit state, where ‖ ‖2 and ‖ ‖2 are the probabilities of
observing |0⟩ and |1⟩ from the qubit, respectively. Geometrically represented using polar coordinates

second qubit. Rotation operator gates   ( ),   ( ),   ( )rotates a qubit state in Bloch sphere around

outcomes were assessed by reaction time (RT), accuracy and error rate (Er). Cognitive biases are
classified by groups: biases of attention (CB a), motivation (CB
mot), memory (CB
mem) and
perception (CB p). The introduction of technology based on the example of advanced companies in
educational activities allows students to develop the skills of effective adaptation to modern working
conditions and increases the effectiveness of education. Expanding the power of research (complex
tests, several stages of processing results, adaptation of test programs to the system of curriculum
studies) will become a stage of mastering neuroplasticity as a new type of competence. To implement
this approach you should describe your task, select stimuli, formulate questions (or trust it to chatbot),
create psychological tests, and, sure, classify terms used for responses and tasks design. Then you will
(
            <xref ref-type="bibr" rid="ref10">10</xref>
            )
use this system with participant and through enough time you can collect biases and heuristics for
training design.
          </p>
          <p>In my research the strongest correlation was between attention, perception and motivation pairs.
Correlation rate between memory and others groups of biases were middle (Figure 12).

Sure, this research is just introductive and very selective because of specific character of such
investigations, technical conditions of equipment and software, possible condition of conscious
observation and psychological features, but I suppose as it is valuable path in this field as these results
will be useful for further researches and development of cognitive optimization of complex systems
and human-computer interaction.</p>
          <p>The main achievement of this research is new approach, which implement opportunity for evaluation
of wide range of cognitive biases immediately. Previous researches mostly concentrate own attention
on certain number of most popular cognitive biases, ignoring less important. Most of researches use
special conditions and simple testing problems. Proposed approach is more universalized and can be
implemented as for learning as for working and professional environments and conditions, carefully
including individual features of mental activity recognition of each attendee.</p>
          <p>Further development and implementation. Artificial part of interaction can be evaluated on
efficiency by index of biasing as human part of interaction. In this case we should and general evaluation
will help to evaluate index of efficiency of cognitive interaction.</p>
