Paper presented at the Merrill-Palmer Conference on Research and Teaching of Infant Development, February 13-15, 1970. (JE)

We describe an integrated theory of individual differences that traces the behavioral development of life history from genes to brain to reproductive strategy. We provide evidence that a single common factor, the K-Factor, underpins a variety of life-history parameters, including an assortment of sexual, reproductive, parental, familial, and…

Biological contributions to cognitive development continue to be conceived predominantly along deterministic lines, with proponents of different positions arguing about the preponderance of gene-based versus experience-based influences that organize brain circuits irreversibly during prenatal or early postnatal life, and evolutionary influences…

This study aimed to investigate the relationships between abilities to initiate and respond to joint attention and symptoms of autism that have, and have not, been theoretically linked to joint attention. Participants were 51 boys and five girls with autistic disorder, aged between 2 years and 6 years 5 months. Measures of joint attention…

Examined four variables affecting children's resistance to deviation: (1) modeling resistance to deviation, (2) modeling alternative activity incompatible with deviation; (3) availability of alternative activity, and (4) attractiveness of alternative activity. It was concluded that the modeling of behavioral inhibition and incompatible responses…

Investigated the number and characteristics of adults experiencing different types of subjective deprivation, and evaluated Cantril's assertion that some of these types of deprivation are ontogenetic in nature. (DP)

The Brazelton Neonatal Behavioral Assessment Scale (BNBAS) was administered to a group of 73 premature infants at approximately 34, 36, and 40 weeks of gestational age. Six behavioral cluster scores and one reflex cluster score were computed for each examination. Repeated measures analyses of variance showed significant steady improvement on all…

This bibliography on approaches to behavior modification with juvenile delinquents lists programs in residential situations, intervention with families, basic education courses, and community-based projects. Virtually every facet of behavior control and modification is covered, including some which are controversial. Citations are not annotated.…

Assumptions that learning is basically concept development and that it is also a process of successive approximations of a terminal behavior lead the author to a definition of concept and a hierarchy of concept development. The nine-stage model of cognitive development is presented in a chart with sample items and instrumentation for each state.…

Analyzed parataxic distortion (low self esteem and attribution of low self-acceptance to the average person), by looking for key qualities of parenting associated with this type of distorted perception. (DP)
