Biological theories Flashcards
The Big Five are in large part genetically inherited, true or false?
true
what is the Technique that looks for the location of specific bits of DNA on genes that might be associated with particular behaviours?
Quantitative trail loci (QTL) approach
what is known as the 3 factor model?
Eysenck
what is the gene Associated with novelty seeking/impulsivity?
Dopamine D4 receptor gene (DRD4)
The longer this gene sequence is, the more over-active the dopamine (reward) system is and the more “thrills” a person seeks out
Dopamine D4 receptor gene (DRD4)
Brains of extreme introverts are ____-aroused and seek to _____ stimulation
Brains of extreme extroverts are ____-aroused and seek to _____ stimulation
over, minimize. under, maximize
what is stability-instability (in relation to arousal)?
Suddenness in how quickly shifts in autonomic arousal occur
Eysenck’s Theory of Arousal proposes that
• Extroverts: ____ nervous system
• Introverts: ____ nervous system
strong, weak
what is the System in the brain responsible for motivating behaviours to achieve goals and positive emotions?
behavioural approach system (approach)
what is the System in the brain responsible for motivating behaviours to avoid potentially threatening situations
behavioural inhibition system (avoidance)
what part of the brain plays a key role in the behavioural inhibition system?
the amygdala
______ is an indirect measure of physiological arousal
salvation
what does the social cognitive theory propose?
A person’s behaviour changes in different situations, but may be stable within given situations
who proposes “If…then” behaviour consistencies?
Walter Mischel
are People’s personality traits consistent across all situations?
no
what is George Kelly’s theory of Fundamental postulate?
- A person’s processes are psychologically channelized by the ways in which s/he anticipates events
- A person is motivated to anticipate what will happen to him or her
High level self-monitoring people……. in a social situation
modify behaviour to match social situation
low level self-monitoring people……. in a social situation
act the same
what is Inter-rater reliability (a behavioural observation)?
Measure of how much agreement there is in rating when using two or more raters or coders to rate personalities or other behaviours
what kind of tests have Problems with inter-rater reliability?
projective tests (Rorschach inkblot test or Thematic Apperceptions Test (TAT))
what method of questionnaires Focuses on questions that characterize the group the questionnaire is intended to distinguish?
empirical
