cognitive Flashcards
What are the key assumptions/ points?
- behaviour is influenced by both conscious and unconscious thoughts
- Internal Mental Processes mediate between stimulus and response
- Humans are information processors that can be compared to computers
What is a schema?
-a cognitive framework of beliefs and expectations
-developed from experience that helps us organize and interpret information in the brain
-used as a reference to help us behave appropriately
What are the advantages of a schema?
-Help us process lots of information quickly
-Stops us from being overwhelmed by environmental stimuli
What are the disadvantages of a schema?
-May develop stereotypes that are difficult to disconfirm
-can distort our interpretations of sensory information leading to perceptual errors
What are theoretical/ computer models?
Simplified, usually pictorial representation of a particular mental process
Based on available evidence
Similarities between humans and computers?
-Both recall and process information
-take data from the outside word and transform it
Differences between humans and computers?
Computers have no emotion
Computers may misinterpret instructions/ have processing errors
Humans have selective memory/ attention
What is cognitive neuroscience?
-scientific study of biological structures that underpin cognitive processes
-interested in which brain regions are involved when we interact, human cognition, attention, how impairments in brain regions may characterise different psych conditions etc
Strengths?
-Has many applications- has been able to explain dysfunctional behaviour
-Scientific- use of models
Weaknesses?
Computer models- important differences between them and humans
Ignores important factors- tells us how processes take place not why
Applications of the approach?
-models of memory have helped us understand how memory works, which has been applied to police interviewing witnesses
- NHS uses Cognitive Behavioral Therapy aiming to restructure faulty thinking and perceptions in depression, following Ellis’ belief that mental disorders develop because of irrational thoughts
-cognitive neuroscience
