Chapter 1 Flashcards
What is mind?
Private inner experience of perception
thoughts
memories
feelings
What is behavior?
Observable actions of human beings
What is cognition?
All mental processes that lead to:
thoughts
knowledge
awareness
What are the cognitive processes?
Mechanisms that underly cognition (thoughts
knowledge
awareness)
Give a few examples of cognitive functions.
(Cognitive functions are the ‘building blocks’ of all complex
behavior)
attention
memory
learning
decision-making
language
perception
motor-skills
imagination
Cognitive neuroscience attempts to understand the
____________ foundations of cognition
Biological
A technique of establishing a causal relationship
between variables
Experiment
Continental rationalism argued that:
Knowledge is innate.
Innate - present from birth, native.
René Descartes
Benedict de Spinoza
Gottfried Leibniz
British Empiricism argued that:
All knowledge is obtained through experience.
John Locke
George Berkeley
David Hume
Dualism concept:
Mind and body are two distinct entities (systems) that interact.
What is JND - just noticeable difference?
(Fechner)
The minimum difference in stimulation that a person can detect 50% of the time
Mental Chronometry is the study of:
cognitive processing speed
1) Simple reaction time: press a button whenever you hear a syllable (RT = 198 ms). → DETECTION RT
(2) Differential/choice reaction time: press ‘k’ when you hear ‘ka’, press ‘t’ when you hear ‘ta’, press ‘p’
when you hear ‘pa’ (RT = 278 ms). → DETECTION RT + DISCRIMINATION RT + DECISION RT
(3) Go/No go reaction time: press ‘k’ when you hear ‘ka’, but do nothing when you hear ‘ta’ or ‘pa’ (RT =
269 ms). → DETECTION RT + DISCRIMINATION RT
The time you need for stimulus
discrimination = (3) – (1) = 71 ms,
and the time you need only for decision making = (2) – (3) = 9 ms.
Time you need to make a decision that includes discrimination = (2) – (1) = 80 ms.
Structuralism is:
Can be achieved by:
(Wundt)
The analysis of the basic elements that constitute the mind.
Achieved by breaking down consciousness into sensations
and feelings via analytical introspection
Behaviourism advocates that:
(Watson)
Advocates that psychologists should restrict themselves to the scientific study of objectively observable
behaviour - what people do.
Logical positivism movement claims:
(Logical empiricism)
Only statements verifiable through direct observation or logical proof are meaningful
Operational definition is
A description of an abstract property in terms of a concrete condition that can be measured.
ex:
Age - years
Height - meters
What happens in classical conditioning
(Pavlolv)
A person or animal learns to associate a neutral stimulus (CS) with a stimulus (US) that naturally produces a behaviour (UR). As a result of this association, the previously neutral stimulus comes to elicit the same response (CR).
CS - conditioned stimulus
US - unconditioned stimulus
UR - unconditioned response
CR - conditioned response
Operant conditioning
(Skinner)
Learning occurs through reinforcement and punishment,
that can both be positive (something is added) or negative
(something is removed)
Gestalt psychology
Phi phenomenon
Cognitive revolution
Empiricism
Scientific method
Falsifiability
Deduction
Induction
Weber’s Law says this about JND:
The just noticeable difference of a stimulus is a constant proportion despite variations in intensity.
