Sex differences in IQ
For overall IQ score, only very small, inconsistent differences between men and women
But for parts of IQ tests, some bigger differences:
o W> M on perceptual speed, word fluency
o M > W on spatial visualization, math reasoning
Wider variation in IQ scores
Almost 60% of the top 1% scores were boys, but almost 60% of the bottom 1 % were also boys,
Slightly more girls were in the average range
“Emotional Intelligence (EI)”
Means one of two different things
o Ability to recognize others’ emotions:
Measured by ability tests; moderate rs with IQ
Some prediction of life outcomes
o Tendency to regulate one’s emotions
Measured by self-report; weak rs with IQ
Basically same as personality traits (e.g. impulse control, empathy, persistence,
self-awareness, self-motivation, social skill)
Predict some life outcomes (as personality does)
What are main ways that people differ in sexuality?
How do these relate to personality?
Why do people differ in sexuality variables?
Schmitt & Buss (2000) did lexical study of sexuality traits factor analyzed peoples self-reports
on sexuality-related adjectives
Found 7 correlated factors, which can produce 3 broader factors:
o Sexual arousal (seductive vs. abstinent)
o Sexual commitment (devotes, monogamous vs. promiscuous, unfaithful)
o Sexual orientation (Heterosexual vs. gay/lesbian)
Relations of sexuality factors with personality characteristics (from Schmitt & Buss, 2000 et al):
o Sexual arousal: Extraversion (++)
o Sexual commitment: Honestly-Humility, Conscientiousness, Agreeableness, Emotionality
(all +)
o Sexual orientation: Openness (+), emotionality (gay +, Lesbian -)
Gangestad & Simpson (1990): “Sociosexual orientation” (SO)
