Chapter 1 pt.3 Flashcards
What is a Paradigm
A system of ideas that dominate science at a particular time
(scientific revolution is one paradigm to another)
The first digital computers developed in the late 40’s. IBM introduced a computer that was available to the public. What were computers used for then?
To analyze data and suggest a new way of thinking about the mind
what was it about computers that caught the eyes of psychologists
How they processed information in stages (input processor –> memory unit –> arethmih unit)
What is the “Information processing approach?”
the idea that our mind processes information through a sequence of stages
Researchers became interested in describing how well the mind can deal with incoming information.
What experiment did Colin Cherry do find out more information on this?
He presented participants with auditory messages, one to the left ear and one to the right, and told them to focus their attention on one of the messages (attended message) and to ignore the other one (unintended message).
He found that they could hear the sounds of the unattended message but were unaware of the contents of the message
Colin Cherrys experiment led Donald Broadbent to propose the first flow diagram of the mind, explain the diagram
Input —->Filter —>detector—> to memory
What are the 3 types of long term memory
Episodic (memory for events like what you did on the weekend)
Semantic (memory for facts)
Procedural (how to ride a bike)
What is Neuropsychology
the study of behaviour of people with brain damage
What is Electrophysiology
Measuring electrical responses of the nervous system
What procedure made it possible to see which areas of the human brain are activated during cognitive activity
Positron Emiision Tomography (PET)
The PET was replaced by the Functional Magnetic Resonance Imaging (FMRI), why?
because it didn’t involve radioactive tracers like the PET did
