Cognitive Approach Flashcards
Define information processing
What the cognitive approach is about, including input, processing and output, and how these work
What are the 3 stages in the Multi store model
Sensory register
Short term store
Long term memory
Define memory
Encoding, storage and retrieval, explained in different ways by different theories
Define forgetting
Not remembering, which has more than one explanation
Define storage
How info is retained in the brain ready for retrieval
Define retrieval
Getting stored info out of memory
Explain info processing
The cognitive approach assumes that info is processed in the brain. Processing is considered to be linear ( info flows though the brain in a way that seems logical). Info is taken in by senses before being processed. Then, when being remembered info is encoded in brain and stored. When remembered it’s retrieved from storage. This is a linear logical process.
What is the cognitive approach
About how info is processed in brain. When info taken into brain through senses it’s recorded, processed, output. This approach examines how this occurs
How do brains work like computers
A computer has input, processing and output. It receives input via a keyboard or a voice recognition device. Unlike a computer, the human brain receives info from senses. Input into computer is more limited compared to brain which receives masses of info all the time. The computer ‘perceives’ all the input whereas brain only perceives small part of info. Once data has been input, computer processes data like the brain. Computer doesn’t make mistakes-brain does. Computer will repeat processing, human brain may not. Output- computer in form of printout or screen display. Brain uses language or written word, body language, emotions SO MORE COMPLEX THAN COMPUTERS
Why is it useful to compare ideas about the brain and a computer
Helps to explain human processing as brain is not well understood
Useful to clarify how brain processes info
One aspect that is controlled in experiments is…..
The info given to the participants is standardised instructions so each ps has same info
What are experimenter effects
They come from cues or signals from an experimenter that can affect the ps response
Cues might be tone of voice or non verbal cues such as gestures or facial expression
What is the double blind technique
Ps not aware which group they are in or what the study is about. Study carried out by someone other than the person who knows who is doing what. Neither ps or person running study know what is expected
What is the single blind technique
Ps are not aware of what is expected but person carrying out study is. This technique stops ps expectations from affecting the results but doesn’t stop the experimenter effects
Which is a better technique …..single blind or double blind
Double blind
