Cognition or Perception is the process of understanding or gaining familiarity of a faculty via thinking, experience or our senses.
Are you slowly and gradually losing your awareness? If so, how can you get your perception back? Well, according to Adam Gazzaley, computers; specifically gaming, improves the brain activity in the prefrontal cortex (Smith et al, 2001). The prefrontal cortex is the part of the brain associated with cognitive control. Adam Gazzaley is a well-known professor in the field of Neurology at the University of California, San Francisco. He also founded the Neurology Imaging Centre. Gazzaley led a team in a study that attempted to prove that when particular cognitive abilities were targeted in the game ‘NeuroRacer' they increased the multitasking ability in elderly individuals (Tun & Lachman, 2010).
Another point is, Gazzaley discovered that the effects of this cognitive training lingered around for a while, sometimes over six months even without regular practice. These effects on the cognitive activity of the test subjects spilled over to their day to day activities. Gazzaley observed that the elderly people even scored higher than the youths who had no training in the game. This exposure also improved their speeds in task accomplishment and switching and also enhanced their executive control functions especially on persons with fewer logical and scholastic advantages (Small et al., 2008).
Though, the Gazzaley study is criticized on the basis that despite claiming that the mental training ameliorates the cognitive degradation in individuals, it is yet to establish the levels of improvement in perception. The cognitive training is yet to be perfected or proven to be permanent on the subjects since it is yet to be measured. Gazzaley based the improvement in cerebral skills on a spike in the brain activity observed on MRIs conducted on the test...

Effect of Internet Usage

...The academic effects of internet usage of MFI 2nd year IT students. Chapter1 Introduction Background of the studies The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve several billion users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW), the infrastructure to support email, and peer-to-peer networks. Most traditional communications media including telephone, music, film, and television are being reshaped or redefined by the Internet, giving birth to new services such as voice over Internet Protocol (VoIP) and Internet Protocol Television (IPTV). Newspaper, book and other print publishing are adapting to website technology, or are reshaped into blogging and web feeds. The Internet has enabled and accelerated new forms of human interactions through instant messaging, Internet forums, and has social networking. Online shopping boomed both for major retail outlets and small artisans and traders. Business-to-business and financial services on the Internet affect supply chains across entire industries. The origins of the Internet reach back to......

...Task analysis and human-computer interaction: approaches, techniques, and levels of analysis Abe Crystal School of Information and Library Science University of North Carolina at Chapel Hill Beth Ellington School of Information and Library Science University of North Carolina at Chapel Hill ABSTRACT In this paper we critically review task analysis models and techniques. These approaches to task analysis are discussed in order to develop a richer picture of human activity, while analyzing their limitations, general weaknesses, and possibilities for improvement. We consider their ability to determine the appropriate set of atomic actions in a task, their effect on workers’ motivational needs, their support of users’ cognitive and sociocultural processes, and their effectiveness in supporting interface design. We note that the major approaches have focused on very different levels of analysis, and call for greater integration of these different levels in task analysis theory. Keywords Task analysis, cognitive modeling, activity theory. INTRODUCTION Practitioners and researchers routinely advocate building user-centered systems which enable people to reach their goals, take account of natural human limitations, and generally are intuitive, efficient and pleasurable to use (Preece, Rogers and Sharp, 2002). Central to the design of such systems is a clear understanding of what users actually want to do:......

...I was really interest by Human behavior as a result of intentional voluntary cognition or less controlled automatic cognition. In the past psychologists believed that we engage in either controlled thinking or automatic thinking, but newer studies reveal that we can engage in both to varying degrees. I maintain that this co-occurrence is commonly experienced during activity on the Internet, especially in individuals who are well acquainted with its use. For those who grew up with a computer like me, browsing the Internet has become a second nature, or automatic process, not unlike driving a car or riding a bike. However, unlike the latter activities one must be in conscious control when seeking out information. To complete the analogy, it would be more akin to the automatic process of driving a car while consciously seeking correct directions on a map. If you were to observe an older adult lacking expertise with computers and someone highly familiar with them, both attempting to locate particular type information, you would find the latter to succeed many times faster. Certainly we must question what effect this will have on our ability to manage controlled and automatic thinking. I would postulate that although creating a degree of frustration, it is also generating a challenge which we as a continuously developing animal will be exposed to ever more frequently. Perhaps an outcome of this may be a more developed form of cognitive processing. True, this is......

Evolution of Cognitive Psychology

...Cognitive Psychology Psych 560 May 20, 2013 Prof. Pitt Cognitive Psychology The brain is one of the major faculties that provide sense to human life. The numerous and various abilities of the human brain are truly amazing. However, although it is a common thought that man may think extraordinarily, human emotions have great influence to how human beings think, and use his brains. It is the reason why any activity facilitated or performed by the brain is called a mental processes or cognition. Cognition refers to the process that involves mental or cognitive ability such as in learning, comprehension, judging, thinking, problem-solving, remembering and recalling (Kendra, 2011). Neisser (2009) defined cognition as the “act of knowing, and cognitive psychology is the study of all human activities related to knowledge”. (Page 1) Cognitive psychology is a part of the larger field of cognitive science and is related to various disciplines in psychology such as neuroscience, linguistics, and philosophy. The main thrust of cognitive psychology is how the people acquire, store and process information. Compared with other dominant approaches in psychology for example, the behaviorism approach which is concerned with the observable behaviors, the cognitive approach focuses on internal mental states. Unlike psychoanalysis which is focused on subjective perceptions, the cognitive......

Cognitive Psychology Definition

...Cognitive Psychology Definition Paper PSY/340 Cognitive Psychology Dr. 07/14/2014 The cognition process study is an integral part of getting familiar with the human nature. Considering the topic of human nature, the most interesting thing to discover is the way people behave themselves, what is ascribed to the study of behavioral psychology. Nevertheless, the way people behave is fully dependent upon what people learn, what do they read, which information they process, and how does it take place. A human's behavior in different situations is just as set of theoretical and practical knowledge received in the process of cognition. All the questions regarding this topic are put under deep scrutiny by the branch of psychology, which is called the cognitive psychology. This kind of psychological studies is one of the most important, as it examines and researches not only what and who we are, but how do we acquire the features we possess. The 18th century was a harsh time for the development of psychology in the role of a scientific discipline. Towards the end of the 19th century psychology was dominated by an approach known as introspectionism. The basis of introspectionism was to study mental processes via a method of subjective self-examination. (Parkin, 2000, p. 1) In the middle of the 20th century, three general movements arose to inspire and shape a cognitive psychology. First of all, after the......

...Cognitive Psychology Definition Paper Jennifer Flynn PSY/360 October 27, 2014 Terry Blackmon Cognitive Psychology Definition Paper Cognitive psychology is the study among psychology that discovers the internal mental processes by encompassing learning, memory, problem solving, perception, thought or language (Galotti, 2014). While still relatively new comparatively as a formal branch of psychology, its roots extend back to Descartes who sought a way to explain how the mind worked, proposing the analogy of a “hydraulic system of nerve function” (Willingham, 2007, p. 26) after he observed animated statues in Saint-Germain-en-Laye. It has been the relentless pursuit of not only how did the mind work but also what exactly constituted the mind that eventually led the foundations of cognitive theory. As psychologists examined how mental processes produced behavior, it was evident a different approach would be needed. The school of thought that arises from tactic is called Cognitivism and is also interested in how people mentally represent information processing (Galotti, 2014). According to ScienceDaily (2014), Wilhelm Wundt, the Gestalt psychology of Max Wertheimer, Wolfgang Kohler and Kurt Koffka, and Jean Piaget was the foundations in this work. However, they presented the theory or segments that articulate children’s cognitive development and the two styles that cognitive psychologist use to realize, detect, and solve problems. These two approaches are......

Attention and Comprehension Chapter 6. Attitudes and Intentions Chapter 7. Consumer Decision Making Chapter 3 INTRODUCTION TO AFFECT AND COGNITION Authors' Overview of the Chapter This is the introductory chapter on consumers' affect and cognition, and it provides a foundation for the rest of this section. Students need to understand the basic concepts presented here in order to apply them throughout the course. We begin the chapter by briefly reviewing the four elements in our basic model, the Wheel of Consumer Analysis. Then we discuss in some detail two broad, internal aspects of consumers' responses--affect and cognition. We describe affect and cognition in terms of two psychological systems that sense, interpret, and respond to information in the environment. The affective and cognitive systems can be thought of as essentially independent, yet highly interrelated modes of psychological response. Affect. Affect concerns people's feelings and emotional reactions. We identify four types of affective responses--emotions, strong feelings, moods, and evaluations--that vary in intensity and level of arousal (see Exhibit 3.2, p. 42). We emphasize that the affective system is......

...11/21/2012 | Submitted to: Mrs. Maria Hutchinson Submitted by: Roger Polanco Introduction to Counseling and Guidance Research On Cognitive and Behavioral Approaches Similarities and differences In psychology many approaches have been discovered and some are still currently in use. There are two approaches, which I feel have much similarities but also differences. I will be explaining the cognitive and behavioral approach. Cognition literally means, “Knowing”. In other words, psychologists from this approach study cognition, which is A ‘the mental act or process by which knowledge is acquired.’ They focus on the way human’s process information, looking at how we treat information that comes in to the person (stimuli) and how this treatment leads to responses. In other words, they are interested in the variables that mediate between stimulus/input and response/output. The main areas of study in cognitive psychology are: perception, attention, memory and language. The essence of the behavioral approach is the statement that all behavior is learned and that when we are born we are like a blank slate. Experience and interactions with the environment make us what we are. We become what we become as a result of forming stimulus-response units of behavior in reaction to the environment. This perspective has been called environmental determinism because it suggests that the environments in which we exist determine us. The second statement is that all behavior can be......

...Between Perception and Behavior, or How to Win a Game of Trivial Pursuit Ap Dijksterhuis and Ad van Knippenberg University of Nijmegen The authors tested and confirmed the hypothesis that priming a stereotype or trait leads to complex overt behavior in line with this activated stereotype or trait. Specifically, 4 experiments established that priming the stereotype of professors or the trait intelligent enhanced participants' performance on a scale measuring general knowledge. Also, priming the stereotype of soccer hooligans or the trait stupid reduced participants' performance on a general knowledge scale. Results of the experiments revealed (a) that prolonged priming leads to more pronounced behavioral effects and (b) that there is no sign of decay of the effects for at least 15 min. The authors explain their results by claiming that perception has a direct and pervasive impact on overt behavior (cf. J. A. Bargh, M. Chen, & L. Burrows, 1996). Implications for human social behavior are discussed. behavior in line with the activated constructs (see also Carver, Ganellen, Froming, & Chambers, 1983; Neuberg, 1988). For example, priming participants with the stereotype of the elderly made participants walk more slowly than participants who were not primed (Bargh, Chen, & Burrows, 1996, Experiment 2). In our view, the notion that behavior is under direct perceptual control is of central importance for the understanding of human behavior. After all, upon......

The research focused on designing as an essentially human activity via consideration of the epistemological and ontological issues involved in constructing coherent design theory. The research investigations led to a clearer understanding of the roles of ontology, epistemology and methodology in design research and this clarification enabled the construction of a post-positivist approach to engineering design theory that better includes social, environmental and ethical factors alongside the existing products of scientific engineering design research. Other contributions to knowledge that emerged from the research process and which underpin the conclusions include; clarification of the terminology and......

Psychol. 20: 1181–1194 (2006) Published online 6 July 2006 in Wiley InterScience ( DOI: 10.1002/acp.1257 Brand Logo and Name Association: It’s all in the Name HEATHER BUTTLE1* and NIKKI WESTOBY2 1 2 Massey University, New Zealand University of Wales, Bangor, UK SUMMARY Despite the expense of designing and the popularity of using logos to represent brands, there is a paucity of information on how such symbols are processed. This series of experiments used Repetition Blindness (RB) to measure implicit association of logos and names that varied in (1) the abstractness of the logo, and (2) the level of familiarity with the logo. RB is a perceptual phenomenon that occurs when two items, presented in a rapid serial visual presentation (RSVP), are encoded along repeated dimensions (e.g. visual, phonological, semantic) resulting in only one item being perceived (Bavelier, 1994; Buttle, Ball, Zhang, & Raymond, 2005; Kanwisher, 1987). Phonological RB was revealed for both abstract and figurative logos and occurred regardless of familiarity. The results suggest that as long as a consumer has the opportunity to be exposed to the name of a logo then logo-name association learning is a rapid process. Copyright # 2006 John Wiley & Sons, Ltd. Companies use logos to convey the unique identity of their products, services, or organizations. A great deal of effort is expended on creating a logo so that it......

Language Essay

...Language Essay Ryan Butler Psychology 360 August 29, 2011 Professor Newlin LANGUAGE Have you ever wondered how we speak? How about why our communication is considered a language and other animal’s communication is not considered language? A wide range of beliefs exist on what defines language. Thus, by exploring the definition of language and lexicon, evaluating language’s key features, the four levels of language structure and processing, and the role of language in Cognitive Psychology, an understanding of what language is becomes clear. Let us begin by defining language and a term named lexicon. LANGUAGE AND LEXICON DEFINITION One big question, when the subject of language comes up, is exactly what language is. What constitutes something as a language? By explaining one definition of a language, and a term associated with language, called a lexicon, a definition of language transpires. Thus, the Willingham (2007) text mentions four certain characteristics communication must possess to, officially, be considered a language.  One of these characteristics is that language must be communicative, and thus be communication between individuals in some form or another.  Secondly, the symbols standing for words must be arbitrary, and thus have no reason for representing a word.  Third, a language must be structured, and not arbitrary.  For example, if I say a dog was walking on a sidewalk I cannot say a sidewalk was walking on a dog. etc.  Fourth, a language must......
