1. Started at critical periods 1. Critical period: a specific window of time during which an event must occur where imprinting occurs 1. Lorenz’s goslings critical period was about 36 hours 1. If goslings didn’t see mother until after that window closed, never imprinted to her 1. After critical period passes, difficult for goslings to establish bonds with their mother or other attachment figures 2. Sensitive period: developmental windows in creatures with more malleable ranges of behaviors 3. Contact comfort (420): positive emotions afforded by touch. Helps us understand why humans find simple touch reassuring 4. The Strange Situation : examined 1-yr olds reactions to separation from mothers 1. Infants behaviors when mother leaves/returns the room 1. Secure attachment (60%): when mom leaves, infants upset. Greets mom’s return with joy. 1. Secure base: uses mom as a rock-solid source of support to which to turn in times of trouble 2. Insecure-avoidant attachment (15-20%): reacts to mom’s departure with indifference and shows little reaction on her return 3. Insecure-anxious attachment (15-20%): reacts to mom’s departure with panic. When mom returns, shows a mixed emotional reaction; try to reach for her yet squirm to get away after she picks him up. “Anxious- ambivalent” 4. Disorganized attachment (5-10%): react to mom’s departure and return with inconsistent and confused set of responses. May appear dazed when reunited. Added later by Mary Main. 5. Mono-operation bias (421): drawing conclusions on the basis of only a single measure 1. Mistake from The Strange Situation : only one indicator of attachment 2. Infants’ attachment styles are attributable largely to their parents’ responsiveness to them 2. Temperament (421): basic emotional style that appears early in development and is largely genetic in origin 1. Types of temperament 1. Sanguine—optimistic 2. Phlegmatic—mellow 3. Choleric—hot-tempered 4. Melancholic—sad 5. Alexander Thomas and Stella Chess 1. Easy infants: 40% babies are adaptable and relaxed 2. Difficult infants: 10% are fussy and easily frustrated
