Attention Cognitive Psychology - 1575 Words

Research carried out on attention has mainly been associated with the selective processing of incoming sensory information. It proposes, to some degree, our awareness of the world depends on what we choose to focus on and not simply the stimulation received by our senses. Attention is often linked to a filter that screens out most potential stimuli whilst allowing a select few to pass through into our conscious awareness, however, a great deal of debate has been devoted to where the filter is situated in the information processing chain (Martindale, 1991). Psychologists have made extensive contributions to this subject matter in the past century. Notable examples include Donald Broadbents filter theory of attention (1958), which set the†¦show more content†¦This buffer was a temporary memory store in which the unselected information could be held in parallel for short periods of time (Styles, 2006). Information can remain in the buffer for processing at a later stage, if this is not the case, it corrodes and is then lost (Martindale, 1991). It is only when the â€Å"information passes through the filter into the limited capacity channel, which is a serial processor, that it is identified† (Styles, 2006, p19). The indication is that therefore, selection from the parallel input is made at early levels of processing, and is consequently an â€Å"early selection model† (Styles, 2006). A number of theorist’s have, however, introduced models that completely reject Broadbent’s Filter model. An example is that of Deutsch and Deutsch’s attention model (Martindale, 1991). Deutsch and Deutsch (1963) offer a model in which all stimuli are fully analysed, with the most significant message determining the response (Eyesnck, 2010). This theory proposes a bottleneck, as the filter is placed closer to the response end of the processing system. This model is recognized as a late-selection model (Deutsch Deutsch, 1963). The Deutsch and Deutsch model was later modified by Norman (1968) who alleges that sensory inputs are processed routinely and instinctively before we consciously know about them. Norman suggests that no signal is filtered out but all are processed to the point of activating the storedShow MoreRelatedBehaviorism And Behaviorism Theories Of Psychology Essay1322 Words   |  6 Pagescredited as the founder of American psychology. He believed in observing everyday psychological experiences such as attention, memory, and reasoning. James also believed that the mind way very active in nature. Behaviorism says that you have to look at psychology in a way that is observable and objective. The main focus was on how we react to stimuli. Unlike Ebbinghaus both James’s view and behaviorism stray from introspection as opposed to observation. Gestalt psychology emphasized people’s tendencyRead MoreCognitive Psychology And Human Behavior930 Words   |  4 PagesCognitive psychology has evolved over the years. Researchers are constantly trying to find new ways to understand and define the human brain. Our memory is quite important in how we function on a day-to-day basis. Our memories help us to remember important functions such as combing our hair, brushing our teeth or getting dressed in the morning. Memories also help us to learn more information. Cognitive psychology refers to the study of human mental processes and their role of thinking, feeling, andRead MorePhysical Exercise and Cognitive Functioning in Children1691 Words   |  7 PagesThe purpose of this study is to look at if physical exercise will help the healthy cognitive development in children and adolescence and this paper will illustrate that the same facts are true for children and adolescence, and will stress the importance of exercise for child ren optimal brain development and growth. The current studies show that physical activity has a positive effect on attention, neuroplasticity and intellectual development in children and adolescence. The studies also seem toRead MoreCognitive Failures Of A Person s Cognitive System844 Words   |  4 PagesA person’s cognitive system can overall be very effective, though occasionally mistakes occur resulting in generalized cognitive failures. Cognitive failures, also known as absent-mindedness, are errors or mistakes people make due to attention slips or memory failures (Reason, 1982). These failures refer to all possible errors within the cognitive system and can be traced to problems with attention, memory, errors created by distractions and errors in the execution of intentions. These include lapsesRead MoreCognitive Psychology Essay1294 Words   |  6 PagesEvolution of Cognitive Psychology Plynia Welty Psych 560 June 11, 2012 Brian Uldall Evolution of Cognitive Psychology Cognitive psychology embarked on a revolutionary journey since the era of Saint Thomas Aquinas (Dr. King, 2012). St. Aquinas was the pioneering mind behind the idea that behavior can be divided into two areas, cognitive and effect. Logging empirical research on a subject provides practitioners a comprehensive view of the subject matter (Dr. King, 2012).

As a person grows older some brain cell dies, shrink, or weaken and cause some decline in brain functions. Some cognitive processes include attention, working memory, long-term memory, perception, and executive control.

These processes include attention, perception, learning and reasoning, (Eysenck and Keane, 2010).There are a number of approaches which can be used within this field, however for the purposes of the essay only two will be compared; cognitive neuroscience and neuropsychology. The aims of cognitive neuroscientists are often similar to those of cognitiveRead MoreChanges And Changes Of Change Blindness Essay1471 Words   |  6 Pagesnotice the change. When observer fails to observe and notice the change major changes and differences introduced into an image at a flick off and on again. People having poor ability in detecting the changes are argued to have limitation of human attention (Hecht-Nielsen McKenna, 2003). Change blindness has provided a wide range of research that has important and practical implications especially in eyewitnes s position and distraction while driving among other areas. In early observation of changeRead MoreInfant Learning: Brain Development Essay1098 Words   |  5 Pagesneural pathways are still being formed in response to stimulation and for this reason, it is extremely important for caregivers and parents to be aware of the many factors that can influence brain development in infants (Marshall, 2011).
