o Early infant/caregiver relationship has major impact on future social
Infant attachment is:
o Secure
Responsive caregivers; become psych healthy adults good relationships,
empathize with others, good self-regulation
o Insecure: anxious/ambivalent not much exploration to new environment
Overbearing and inconsistent parents
As adults desire close relationships but worry
o Insecure: avoidant fear of loss can result in violent actions diminished
capacity for their victims or relationships
Distant parents rarely cry during separation or reunion with parents,
infants never know when and how parents will respond to their needs
Difficulty forming intimate relationships as adults want to have close
relationships but worry about the relationships returning the affection
become more obsessive and preoccupied with relationships especially
spouse or partner
Lack of Empathy characteristic of aggressive and antisocial individuals, predispose to be
more aggressive and violent to others
Affective empathy: e.g., psychopath has cognitive empathy but cannot get affective
o Concern for others; desire to alleviate (make less severe) distress
o Experience aother’s eotios
Cognitive empathy:
o Ailit to uderstad fro aother’s poit of ie
o Understand aother’s eotios

Many argue IQ tests are culturally & socially biased
IQ scores strongly predictive of school performance
IQ is not equivalent to intelligence
o Intelligence = broad, all-encompassing ability, different definition to another
