individual diiferences l5-9 Flashcards
sex vs gender definitions
sex = the biological and physiological characteristics that define male, female and intersex people.
gender = the socially constructed roles, behaviours, attributes and activitities that a given society considers appropriate for men, women and non-binary people.
why do sex differences matter?
- women are less likely to major in stem subjects
- 75% undergraduate psych women, only 18% APA journal editors are women.
- women are more likely to leave faculty jobs and less likely to be promoted at every age and stage of work.
sex differences in general intelligence
- most studies show no difference in IQ levels
- difficult to measure as tests are designed to be gender neutral
- males better at some factors and females at others, no difference overall.
sex differences in spatial ability
-tasks include: spatial perception, mental rotation, spatial visualisation, spatio-temporal ability
generation and maintenance of a spatial image.
- males have larger advantage on all tasks except spatial visualisation across infants and older adults. (ability to mentally manipulate 2d and 3d figures)
- women are more likely to use landmarks and relative directions, where men are more likely to use cardinal directions (N, E,S, W)
- when only one solution was given, there was no difference
sex differences in verbal abilities
- women do better than men in verbal reasoning and writing ability
- young girls are more proficient in language skills than boys
- effect sizes can be small but robust female advantage and across lifespan
sex differences in memory and attention
- some evidence to suggest women are more sensitive to some attentional cues and distraction than men
- large female advantage in episodic memory, but depends on nature of the task.
object/person orientation
reasons for sex differences
- studies suggest men are on average biologically prediposed to systematize, and women are prediposed to empathize, communicate and care for others -> lack of replication and not alot of evidence to back it up
- studies on infant perception show no sex differences
extreme male variability
reasons for sex differences
= males generally display greater variability in traits than females do.
- girls grades are more consistent overall, with more males at both ends of the tails
- more males in the STEM subjects pool
hemispheric asymmetry
reasons for sex differences
= functional differences between the left and right side of the brain
- Levy proposed that males have greater asymmetric brain organisation, with the left specializing in verbal processing and the right for spatial processing.
- male brain siperior in spaitial skills, female for verbal skills.
- no evidence that this drives differences in cognitive function.
stereotype threat and role models
reasons for sex differences
- negative stereotypes affect female mathematical performance
- women more strongly affected by stereotypes than men
- Cognitive performance of people with disabilities higher when experimenter refers to having a disability
social explanations of sex differences
- stem differences result from stereotypes that women are less able than men
- environmental factors (gendered toys from a young age)
types of personality stability
- measurement (reliability)
- homotypic
- heterotypic
- mean level
- rank order
- by nature, personality traits should be stable across the lifespan
homotypic vs heterotypic stability
homotypic = the degree to which people express the same thoughts, feelings and behaviours across time.
heterotypic = consistency of underlying personality traits
- different observable manifestations at different ages
- for example a five year old may cry and hide behind their parents, but an adult would not do this
rank order vs mean level stability
rank order = whether a persons ranking relative to their cohort remains the same ( correlation of a specific personality traits assessed at two moments in time, at different ages.)
mean level = whether the absolute scores on each factor are stable (whether the rank order of individuals in a certain trait is maintained over time)
Rank-order stability is about how people’s positions relative to each other stay the same over time.
Mean-level stability is about whether the average level of a trait stays the same or changes over time.
rank order and mean level stability in context for understanding
if a study on extraversion shows that the ranking of individuals on extraversion remains fairly consistent between adolescence and adulthood (i.e., the person who was most extroverted as a teenager is still among the most extroverted as an adult), the study demonstrates rank-order stability. However, if the average level of extraversion in the entire group decreases with age (i.e., as people mature, the group becomes less extraverted), the study demonstrates mean-level stability.
how is personality stability studied
cross sectional -> can study mean level stability, confounded by cohort effects
longitudinal -> can study rank order and mean level stability, based on a single cohort questions generalisability,
social vitality
= defined in terms of traits such as socialability, high energy levels, positive affect, associate with others that are similar to self.
- increases at college age
- decreases from 22-30, then from 60-70
- is otherwise stable
- decreases with age?
social dominance
= is defined in terms of domiance, independence and self-confidence in social contexts
- consistent pattern of increase until age 40, there fore after consider extraversion is decreasing?
age related changes across the big 5 personality traits
agreeableness:
- overall pattern of increase, inconsistent results in older age
- study found increase in 50-60 age range, others found an increase in young adulthood but a slight decrease in older adulthood.
concientiousness:
- small increases in adolescents and college age
- main increase from 20-50, then 60-70
- differences found between samples, one study found decrease in older adults
neuroticism:
- lower neuroticism and increased emotional stability across the lifespan
openess:
- increased at college age
- flat/ decreases therefore after
cumulative continuity principle
= the idea that early behavioral patterns and experiences can shape and influence an individual’s future behavior over time.
- personality traits increase in rank order consistency across lifespan
-Increasing stability with age although much slower increase after age 25 - little difference between traits, more variability in A and O
why do we change across the lifespan
- genetic predisposition
- largely genetic in childhood but only plays small role in adulthood
- life experiences (education, career, children)- closely associated with age
- changes seen cross culturally
- environment can change personality with reward/punishment (military)
- different transitions and turning points one experiences in life at different times
