The Two Modes of Cognitive Processing Essay - 1792 Words

The Two Modes of Cognitive Processing Models and experiments presented throughout the Cognitive Psychology course indicate that within the Information Processing framework, 2 distinct modes of cognitive processing exist. The first, concerned with low level cognition is characterised by processing which is parallel, automatic, bottom-up and not very limited by capacity. This is most clearly demonstrated by the number of things we can hear simultaneously, see simultaneously, smell, taste and feel simultaneously. This type of low level cognition, along with skills which have been proceduralised, can also be performed automatically; performed without conscious attention. Automatic tasks do not†¦show more content†¦The distinction between these two modes of cognitive processing, however, is not that clear cut. For instance, tasks are not usually totally automatic nor totally attentional; when automatically swimming up and down a pool, we may be focusing our attention on a piece of music, but we are also aware of o ther swimmers and we usually pay enough attention to avoid swimming in to them. Neither is processing usually exclusively top-down or bottom-up, most tasks involve both types of processing in combination. Except maybe, when asleep, we are constantly receiving bottom-up data through our 5 senses. We are also constantly reacting to these stimuli by applying top-down interpretations from our stored general knowledge representations. On the face of it, perception would seem to depend heavily on bottom-up processing (receiving data from stimuli) and memory on top-down, conceptually-driven processing, as remembering depends on retrieval of stored information. But in fact, perception can be affected by the perceivers expectations or by general principles such as size constancy, and remembering is performed in context, taking account of environmental cues. Gregory (1973) made use of visual illusions, such as the Ponzo perspective illusion to show how top-down processes affect perception. His view was that perceptionsShow MoreRelatedCooperation Is At The Heart Of Human Social Life Essay1301 Words   |  6 Pagesrequire cognitive resources: „We fully expect that social mindfulness [†¦] will be undermined by competing sources of attention (cognitive load), time pressure, or alternative sources of distraction that conflict with executive functioning that enables people ’to see‘ the consequences of one‘s actions for othersâ€Å" (p. 21). This suggests that social mindfulness should be increased in situations triggering a deliberate processing mode which is, in turn, characterized by sufficient cognitive resourcesRead MoreLink Between Spatial Attention And Social Anxiety1480 Words   |  6 Pagesattention to social anxiety. Over the past two decades there has been seen an exponential popularity in pinpointing the exact attentional mechanisms which underlie such selective processing in models of anxiety(Clarke et al 2013). There are several different models of anxiety processing, however in this paper only the cognitive model of anxiety will be used. This model will be used because it uses both automatic and controlled processes that disrupts the cognitive economy to induces a state of anxietyRead MoreWhat is an Attitude?

He defines attitudes based on more contemporary ideas and research by saying, ‘†¦we define an attitude as an overall evaluation of an object that is based on cognitive, affective and behavioural information’ (p.4). There seems to be much conflict of ideas, between theorists as to which component (cognition, affect or behaviour) holds more salience in the formation and change of attitudes. As the emphasis of attitudesRead MoreStudy Program Essay690 Words   |  3 Pagestestimony, and less influenced by more scientific actuarial expert testimony. By applying cognitive-experiential self-theory (CEST) to juror decision-making, the present study was undertaken in an attempt to offer a theoretical rationale for the findings (Krauss, Liberman, Olson, 2004). Based on past CEST research, 163 mock jurors were either directed into a rational mode or experiential mode of processing (Krauss, Liberman, Olson, 2004). According to this article, consistent with CEST and inconsistentRead MoreThe Theory Of The And Social Theory1468 Words   |  6 Pagesaccording to an informal survey (Nichols Mallon, 2006). Greene dual moral processes For a long time, theories of moral psychology largely ignored the role of cognitive reasoning in reference to moral judgment; instead the research focused predominantly on the role of emotion and affective intuition in moral judgments. Typically, two research questions are the focus in moral psychology: â€Å"Why do we care about what others do even if what they do does not affect us?† and â€Å"How can we decide whetherRead MoreFacial Recognition1170 Words   |  5 PagesCognitive processes involved with face recognition To human beings, facial recognition is not only essential for identification of persons in the social context, but also a vital social tool. There are various reasons why facial recognition process is a vital to human beings. Facial recognition serves an essential purpose of identifying members within our society; as a result, we are able to select those that we can socialize with that aid our survival in society. For instance, the males areRead MoreThe Intensity Of Ventral And Dorsal Streams921 Words   |  4 Pagesvision. Since the attention binds all features of a specific object, it needs longer latencies for this process by using recurrent connections (Lamme Roelfsema, 2000). Furthermore, there are two ways to utilize sensory information, reactive mode (feedback) and predictive mode (feedforward). In reactive mode, we do not know about the sensory input until we get it. Thus, our system reacts and uses the information as feedback. As we become better, less feedback is us ed, and the brain works in a predictiveRead MoreThe s Knowledge Conversion Theory1199 Words   |  5 Pagesinformation processing; input-process-output. One significant shortcoming of this paradigm is the fact that it demonstrates a passive and static view of organizations. Processing of information in this case focus on solving problems by prioritizing incoming information with total disregard for what the organization itself creates. An organization that truly believes in adapting to changes within the environment should emphasize knowledge creation as opposed to only aiming at efficient processing of informationRead MorePsychoanalytical Approach And Cognitive Approach1434 Words   |  6 Pagesperspectives however two of them are going to be discussed. The two perspectives which will be mentioned are Psychoanalytical Approach and Cognitive Approach. Firstly there will be and introduction of each perspective, its strengths and weakness. Secondly an evaluation of how key theorists have applied these two perspectives. Also include the contemporary issues in which these perspectives have been applied. Lastly an analysis of the similarities and differences between the two perspectives. PsychoanalysisRead MoreLearning Styles As A Student s Learning1454 Words   |  6 Pageshemispheres. There is a right hemisphere and a left hemisphere. Each of those hemispheres has its own strategies and specific functions when receiving new information, in terms of cognitive, affective, and physical actions and activities (Duman). The right hemisphere is in charge of spatial reasoning and visuospatial processing, whereas the left hemisphere is in charge of language function, which is incorporated in nearly everything a person learns (Cuevas). Spatial reasoning is the capacity to understand
