This paper considers how such intelligent agent to perform specific tasks, face problems, or characteristics could be applied to improve intelligent agents and “think” certain “thoughts” when placed in various Agent how it would impact work performance.

Ferber [10] defines an agent as a physical or virtual entity, which can act in an environment, communicate directly with other agents, is driven by a set of tendencies, and has resources of its own. An agent is also Categories and Subject Descriptors capable of perceiving its’ own environment and behaves in a H.5.3 [INFORMATION INTERFACES AND manner, which leads to satisfying objectives, while accounting for PRESENTATION]: Group and Organization Interfaces - the resources and skills available to it and the way it perceives, Computer-supported cooperative work, Organizational design, represents, and communicates [10]. Some AI theorists believe that Theory and models intelligent agents will evolve through three stages: 1) personal assistants (simple independent entities), 2) specialized agents (capable of communicating with each other), and eventually 3) General Terms autonomous agents that act on our behalf. If these “predictions Performance, Design, Human Factors, Theory apply to agent evolution in general, then you can expect to see a growing community of agents that become more and more Keywords interconnected while taking ever greater degrees of autonomy,” artificial intelligence, intelligent agents, personality theory suggests Barker [2]. In a few years, agents may be collaborating and cooperating across the web, delivering a wide variety of services and products just like human workers currently do [13]. 1. INTRODUCTION When attempting to design an agent, who is as, or perhaps, more As the pace of business and industry quickens, the complexity of intelligent than humans, it is necessary to incorporate a vast array the business world and the environment in which enterprises of human characteristics and psychological aspects into the agent, operate increases daily.

It may be possible to assume that just as humans do, the the manager, at all levels, to make more numerous decisions than “thinking” that agents do is resultant of interactions between a ever before. The manager is confronted with increasingly complex number of cognitive components or cognitions, which may problems and situations more often and decisions must be made in generally be referred to as mental states. The term mental state less time. The problems are even more confounded with today’s may be questionably applied here because it leads to the “information explosion,” the astronomical generation of volumes assumption of a certain idea of sequential processing in cognitive functioning for an agent [10].

Mitroff [14];[18] has proposed that an information system consists of (at a minimum) one person. That person, like every In his book, The Design of Inquiring Systems, Churchman [8] person, has a certain psychological type. Mitroff has successfully examined how computer-based inquiring systems would behave if applied the Jungian typology to demonstrate how differently these they were designed based on one of the epistemologies of five personality types approach decision making and problem solving. major western philosophers (i.e., Leibnitz, Locke, Kant, Hegel, or He has explored the impact of the differing personality functions Singer).

He developed a unique paradigm for explaining the personality and performance differences between people. According to Jung, when we can systematically distinguish people by their dominant personality function we are simply referring to 3. 1 Data Acquisition Issues the way in which they most often behave. “The psychological Aleksander [1] defines perception, one of several vital thinking type characterizes thus a general habitus, which naturally can characteristics, as encompassing all sensory inputs. Different appear within the limits of the typical in all individual variations, effects of inputs may vary according to where they enter into according to the social, mental, and ethical plane,” explains Jacobi specific regions of the mind’s state structure or possibly the [11]. context in which an agent receives the information [1]. Specifically through perception, an agent is able to obtain Jung divided personality along four salient functions, each one information about the world, which allows it to prepare its action describing a way of processing and evaluating the “things one by pursuing its’ goals [10]. “The perceptive system constitutes a encounters” in the world [9]. Jung believed that the basic door between the world and the agent, which gives it access to a functions are constitutionally present in every individual and that certain ‘conception of the world’ in which its’ reasoning and its they form the structure of consciousness. He believed that these actions are significant” [10]. An agent may also act as a result of functions are automatically and unconsciously called into action motivations, which constitute the basic material for the foundation when aroused by a stimulus or problematic situation. Each of tendencies. function contributes a part of an individual’s make-up and their Jung spoke of perception as a conscious form of “psychic energy” Thinking: Pure thinking types rely primarily on cognitive and subdivided this activity into two basic and opposing processes for judgement, by first recognizing the meaning or functions, “sensation” and “intuition.” He stated they are purpose and then forming a concept of it [3]. If an individual is a “irrational” functions because they seem to work not with pure thinking type, information will be entirely symbolic, an judgments, but with mere perceptions, without any real evaluation abstract system, model or string of symbols devoid of almost any or interpretation [11]. Jung’s concept of perception and its empirical content. They are characterized by systematizing and functions are what Mitroff has referred to as the data input evaluate by forming models and making rules. Thinking types can dimension. Mitroff’s data input dimension is a continuous become so model bound, that they may be unable to understand a function anchored by two antithetical ways of gathering data: situation unless they are able to create one [14]. “sensation” and “intuition.” Data input describes not only the kinds of data initially taken in but more fundamentally, what is Feeling: Pure feeling types rely primarily on affective processes regarded as data in the first place [18]. and value for judgement. Therefore, they take moral stands and make moral judgements [14]. Feeling types are concerned with Sensation: The pure sensation type pertains to individuals who the whole rather than the relationship between its parts and base are concerned with detailed facts. They may be data bound and their evaluations on concepts including nice and nasty, good and can to go on collecting data forever [14]. The pure sensation type bad, agreeable and disagreeable, beautiful and ugly, and pleasant perceives objects in isolation and detail. Sensation types need to and unpleasant [9]. take a complex situation and break it down into very small parts [18]. Sensation focuses awareness of things as they appear and When viewing and experiencing the world, there is no right or need to deal with things like shape, color, and arrangement of wrong perspective, according to Jung [18]. Just as we do not things. If an individual is a sensation type, information will be always see accurately, does not mean that intuition is always entirely empirical, devoid of almost any theoretical content [14]. correct, for example. Or that thinking is better because it happens Sensation types simply relate to the actual state of things [9]. to be named after one of our main mental functions [9]. Intuition: The pure intuition type is an individual who perceives objects as possibilities. They look through the facts and beyond them. They tend be too data free and form inexplicable hunches or 3.3 An Example conclusions where there may be no established facts. Strategy As previously established, information systems consist of several making and envisioning future possibilities and consequences are different people with varying psychological types, such as the strengths of the intuition type [14]. Intuition types integrate thinking, sensing, feeling, or judging, who will encounter details into wholes or larger patterns. Therefore, only larger situations and resulting problems. Individual approaches to wholes and possibilities are considered real information [18]. circumstances and information may vary greatly, depending on the method of generating evidence, how the evidence is presented, their own psychological type, and how familiar they are with the information. For the manager, information is the evidence upon 3.2 Data Processing Issues which his decisions will be based. Therefore, every corporation In order to distinguish between various perceived inputs, a needs all kinds of managers. For example, some managers will person’s awareness must be established involving the entry of rely on basic observations of events like accounting data, others specific external events and information into the state structure of will rely on basic abstract reasoning like marketing models and the system. The same idea of awareness applies when input is others will rationalize through debate. While planning and received internally. Although in the case of internal inputs, the strategizing is the strength of the intuitive type, day-to-day mind or system would interpret the input by exploring parts of its operations management is best suited for the sensation type. A state structure, which are related to its’ past experience. Once management system comprised of only intuitive managers will awareness is established of single or various inputs, attention then always live in the future and won’t pay proper attention to the comes into play [1]. present. A management system comprised solely of sensation type managers may be too limited and bound by the current set of According to Aleksander [1], attention is the act of selecting available facts. They will be unable to envision future between two different percepts or thoughts, which possibly possibilities, have a short planning horizon, and lack innovation. involve either humans or systems switching thoughts from one Systematizing and rule making is the forte of the thinking type, idea to another. What determines how the selection is made while assessing value and taking a moral stand tends to be the involves will. Free will involves feeling free to think of feeling type’s strength. A management level consisting entirely of continuing one way first and then another, or even of making a thinking type managers will be so model bound since their first completely arbitrary choice [1]. Here, “thinking” and “feeling” and instinctive response to any situation is to formulate models are the opposing functions that embody this activity, which Jung and to make rules. Unless they do this they will not be able to calls judgement. Both functions are characterized as rational understand a situation or deal with it effectively. Eventually, they because they involve value and cognition [11]. Mitroff [18] refers will “become victims of and slaves to their own categories and to the judgement dimension as a continuous function anchored by systems” [14]. A management system made up of managers of the two antithetical ways of reaching decisions: “thinking” and feeling type will lack attention to detail, habitually generalize, and “feeling”. He calls this the decision-making dimension, which see “black and white” exclusively as they can only appreciate a refers to how data is processed [18]. complete relationship rather than separate parts. Similarly, let us now consider the behavior of an intelligent agent knowledge, thus avoiding getting stuck. Commonsense that is assigned a psychological type. For instance, observe knowledge must be programmed with several representations of several agents crawling through websites looking for URLs. One the information, which is adequate and provides the ability to agent might be impressed by the appearance of a site; it’s switch to a new representation or understanding, if one of them awareness focused on the shapes, color and layout of the site. fails. Besides applying basic human “thinking” concepts into the Another may perceive the site in terms of potential profitable design of an intelligent agent, Minsky [17] emphasizes that the markets. A third agent may be prompted to recall the history of basic processes of perception, awareness, and attention are not the the Internet and the evolution of global business and technology, only thing that must be considered. Because there is so much upon arrival at the site. A fourth may consider how much it would information available to agents, in regards to the activities of enjoy investing the product this particular site is marketing. humans, the agent must not only simply understand the inputs in Obviously, as demonstrated by the four possible approaches taken one particular way. Eliminating the programming limitations of by each agent in this example, individual agents possess specific the past can lead to solving the types of problems that agents are qualities, which may characterize them as sensation, intuition, designed for and allow them to “think” just as humans do [17]. thinking, and feeling types, respectively. These four different characteristics become apparent in situations such as these where AI models currently exist which attempt to map cognitive and an agent assesses and perceives the same website in it’s own emotional characteristics of humans [15]. Since personality is also individual manner. Each of the four agents in this example in an essential human quality, then perhaps the Jungian typology particular detect elements of the site in a different way, and the system should be incorporated into AI models, as well, and same site means something different to each one of them. The especially for ASCW. For instance, each function could be agents are designed to acquire and focus on certain specific mapped based on the different dimensions. Differing amounts of elements, while other elements may be ignored simply because senses, intuitive possibilities, logic and rules, and value could be they have not been designed or programmed in an agent’s specific translated into AI code depending on the situation. For example, way of “thinking.” Boole investigated the fundamental laws of the mind’s operation and gave expression to them in symbolic, mathematical language. Employing varying types of people (or agents) who possess One can attempt to use that language and those laws in such a way diverse psychological types will ensure that important information as to facilitate the solutions of certain problems facing managers is attended to and miscellaneous information, which may not be and intelligent agents in management situations [5].

This pertinent elements of the decision situation and its assigned may be useful in situations where timely resolutions to problems psychological function and thus, virtual personalities would are needed.

Accordingly, a situation and will ensure successful treatment.

Suppose we change one or all of these conditions. How successful resolution. By combining the various types in ASCW, does changing these assumptions affect the overall design? Would situations should not arise where a group is bound by information the same intelligent system designs be effective? Could we predict and it may be easier to create effective strategies where the future and ultimately improve performance? will be considered, but focus will remain on the present task at hand. 4.

For example, when modes or psychological functions characterize the Jungian one solution to a problem is seemingly unsolvable or something typology. Jung differentiates these four functions from one else goes wrong, a “personality challenged” agent might get stuck another “…because they are neither mutually relatable nor [16]. mutually reducible,” and because they exhaust all the given possibilities.

An intelligent agent with equilibrium would be Advances in design may provide agents with more human able to easily move to a new path of data acquisition or characteristics and knowledge, allowing them to ultimately “be” processing. human. But first, attempts must be made to thoroughly understand human thinking and personality, including all of its structures and Early AI researchers designed systems and programs, which processes. Once Jung’s four functions are understood and automatically applied specific rules. However, new systems have embraced, it is inevitable that personalities will be easier to detect the capability to program increasing, basic, commonsense and develop in agents. 5.
