Overview of the consequences of cognitive neuropsychology

It was this last requirement, fundamental to cognitive psychology, that was one of behaviorism's undoings.

Brain injury

For example, lack of understanding of overview of the consequences of cognitive neuropsychology internal mental processes led to no distinction between memory and performance and failed to account for complex learning Tinklepaugh, 1928; Chomsky, 1959. Cognitive psychology became predominant in the 1960s Tulving, 1962; Sperling, 1960.

Since 1970, more than sixty universities in North America and Europe have established cognitive psychology programs. Assumptions Cognitive psychology is based on two assumptions: There has been much recent debate on these assumptions Costall and Still, 1987; Dreyfus, 1979; Searle, 1990. Often, the predictions of the models are directly compared to human behaviour.

With the ease of access and wide use of brain imaging techniques, cognitive psychology has seen increasing influence of cognitive neuroscience over the past decade. There are currently three main approaches in cognitive psychology: Experimental cognitive psychology treats cognitive psychology as one of the natural sciences and applies experimental methods to investigate human cognition.

Psychophysical responses, response time, and eye tracking are often measured in experimental cognitive psychology. Computational cognitive psychology develops formal mathematical and computational models of human cognition based on symbolic and subsymbolic representations, and dynamical systems. Neural cognitive psychology uses brain imaging e. The three approaches are often inter-linked and provide both independent and complementary insights in every sub-domain of cognitive psychology.

Sub-domains of Cognitive Psychology Traditionally, cognitive psychology includes human perceptionattentionlearningmemoryconcept formationreasoningjudgment and decision-makingproblem solvingand language processing. For some, social and cultural factors, emotionconsciousnessanimal cognitionevolutionary approaches have also become part of cognitive psychology. Those studying perception seek to understand how we construct subjective interpretations of proximal information from the environment.

  • The theoretical analysis of attention has taken several major approaches to identify the mechanisms of attention;
  • The consequence includes memory loss, behavioral and personality change, headache and pain etc;
  • The structural imaging deals with the structure of the nervous system and the functional imaging used to diagnose metabolic diseases and lesions on a finer scale.

Perceptual systems are composed of separate senses e. Current research also focuses on how these separate representations and modules interact and are integrated into coherent percepts. Cognitive psychologists have studied these properties empirically with psychophysical methods and brain imaging. Attention solves the problem of information overload overview of the consequences of cognitive neuropsychology cognitive processing systems by selecting some information for further processing, or by managing resources applied to several sources of information simultaneously Broadbent, 1957; Posner, 1980; Treisman, 1969.

The theoretical analysis of attention has taken several major approaches to identify the mechanisms of attention: Learning improves the response of the organism to the environment. Cognitive psychologists study which new information is acquired and the conditions under which it is acquired. The study of learning begins with an analysis of learning phenomena in animals i.

Cognitive studies of implicit learning emphasize the largely automatic influence of prior experience on performance, and the nature of procedural knowledge Roediger, 1990.

Studies of conceptual learning emphasize the nature of the processing of incoming information, the role of elaboration, and the nature of the encoded representation Craik, 2002. Those using lesion and imaging studies investigate the role of specific brain systems e. The study of the capacity and fragility of human memory is one of the most developed aspects of cognitive psychology. Memory study focuses on how memories are acquired, stored, and retrieved. Memory domains have been functionally divided into memory for facts, for procedures or skills, and working and short-term memory capacity.

The experimental approaches have identified dissociable memory types e. Brain imaging and lesion studies identify separable brain regions active during storage or retrieval from distinct processing systems Gabrieli, 1998.

Concept or category formation refers to the ability to organize the perception and classification of experiences by the construction of functionally relevant categories. The response to a specific stimulus i. The ability to learn concepts has been shown to depend upon the complexity of the category in representational space, and by the relationship of variations among exemplars of concepts to fundamental and accessible dimensions of representation Ashby, 2000.

Certain concepts largely reflect similarity structures, but others may reflect function, or conceptual theories of use Medin, 1989. Computational models have been developed based on aggregation of instance representations, similarity structures and general recognition models, and by conceptual theories Barsalou, 2003. Cognitive neuroscience has identified important brain structures for aspects or distinct forms of category formation Ashby, Alfonso-Reese, Turken, and Waldron, 1998.

Human judgment and decision making is ubiquitous — voluntary behavior implicitly or explicitly requires judgment and choice. The study of decision making has become an active topic in cognitive neuroscience Bechara, Damasio and Damasio, 2000.

Original investigations of reasoning focused on the extent to which humans correctly applied the philosophically derived rules of inference in deduction i. These were extended to limitations in reasoning with syllogisms or quantifiers Johnson-Laird, Byne and Schaeken, 1992; Rips and Marcus, 1977.

Inductive reasoning, in contrast, develops a hypothesis consistent with a set of observations or reasons by analogy Holyoak and Thagard, 1995. Often reasoning is affected by heuristic judgments, fallacies, and the representativeness of evidence, and other framing phenomena Kahneman, Slovic, Tversky, 1982. Computational models have been developed for inference making and analogy Holyoak and Thagard, 1995logical reasoning Rips and Marcus, 1977and Bayesian reasoning Sanjana and Tenenbaum, 2003.

The cognitive psychology of problem solving is the study of how humans pursue goal directed behavior. The computational state-space analysis and computer simulation of problem solving of Newell and Simon 1972 and the empirical and heuristic analysis of Wickelgren 1974 together have set the cognitive psychological approach to problem solving.

Solving a problem is conceived as finding operations to move from the initial state to a goal state in a problem space using either algorithmic or heuristic solutions.

The problem representation is critical in finding solutions Zhang, 1997. Expertise in knowledge rich domains i. Problem solving may engage perception, memory, attention, and executive function, and so many brain areas may be engaged in problem solving tasks, with an emphasis on pre-frontal executive functions. While linguistic approaches focus on the formal structures of languages and language use Chomsky, 1965cognitive overview of the consequences of cognitive neuropsychology has focused on language acquisition, language comprehension, language production, and the psychology of reading Kintsch 1974; Pinker, 1994; Levelt, 1989.

Psycholinguistics has studied encoding and lexical access of words, sentence level processes of parsing and representation, and general representations of concepts, gist, inference, and semantic assumptions. The neuroscience of language has a long history in the analysis of lesions Wernicke, 1874; Broca, 1861and has also been extensively studied with cognitive imaging Posner et al, 1988.
