Reliability: how consistent the result is & validity coefficient: how accurate the result is: desiderata for a scientific personality theory. Lecture 2: human evolution: the evolutionary process. Personality as a product of the evolutionary process. From an evolutionary perspective, the human mind can be seen as a set of psychological adaptations inherited form our pleistocene ancestors who confronted the problem of living in small group as hunter-gatherers: the attachment system: An evolved, goal directed behavior system that promoted proximity-seeking to caregivers when the infant feels threatened and secure-base behavior (exploration) when the infants feels safe. Quality of mother-infant interaction predicts differences across infants in their response to the strange situation, where three patterns of attachment were observed; secure, resistant, avoidant.
