Neuropsychological Performance Of Sexual Assaulters And Pedophiles, Monte L. Scott, James K. Cole, Stephen E. Mckay, Charles J. Golden, Kenneth R. Liggett Jan 1984

Neuropsychological Performance Of Sexual Assaulters And Pedophiles, Monte L. Scott, James K. Cole, Stephen E. Mckay, Charles J. Golden, Kenneth R. Liggett

Department of Psychology: Faculty Publications

Persons who had been arrested for sexual assault were administered the Luria- Nebraska Neuropsychological Battery and the results compared to a group of normal controls. The sexual assaulters performed significantly worse on 7 of the 14 scales of the battery. The data were then broken down into three groups: (1) those who had forcibly assaulted postpubescent victims, (2) those subjects who had sexually molested a prepubeseent child, and (3) normal controls. A discriminant analysis correctly classified 68% of the subjects on the basis of their neuropsychological performance alone.

Optimal Foraging Theory And The Psychology Of Learning, Alan Kamil Jan 1983

Optimal Foraging Theory And The Psychology Of Learning, Alan Kamil

Avian Cognition Papers

The development of optimization theory has made important contributions to the study of animal behavior. But the optimization approach needs to be integrated with other methods of ethology and psychology. For example, the ability to learn is an important component of efficient foraging behavior in many species, and the psychology of animal learning could contribute substantially to testing and extending the predictions of optimal foraging theory.

Spatial Learning As An Adaptation In Hummingbirds, Susan Cole, F. Reed Hainsworth, Alan Kamil, Terre Mercier, Larry L. Wolf Jan 1982

Spatial Learning As An Adaptation In Hummingbirds, Susan Cole, F. Reed Hainsworth, Alan Kamil, Terre Mercier, Larry L. Wolf

Avian Cognition Papers

An ecological approach based on food distribution suggests that hummingbirds should more easily learn to visit a flower in a new location than to learn to return to a flower in a position just visited, for a food reward. Experimental results support this hypothesis as well as the general view that differences in learning within and among species represent adaptations.

Young Children's Age Group Conceptions Of Social Relations: Social Functions And Social Objects, Carolyn P. Edwards, Michael Lewis Jan 1979

Young Children's Age Group Conceptions Of Social Relations: Social Functions And Social Objects, Carolyn P. Edwards, Michael Lewis

Department of Psychology: Faculty Publications

Previous research has shown that by age 3-4, children classify the human world into age groups: babies, “little kids,” “big kids,” young adults (“mommies and daddies”), and old adults (“grandmothers and grandfathers”) (Edwards, 1984).. This study investigates young children’s concepts of age roles, that is, their expectations about what behavior makes most sense or is most appropriate for each age group. Study 1 was conducted at two daycare centers in the greater Princeton area, with 24 African-American and 24 European-American children aged 3.6 to 5.9 years. Each child was told a series of stories involving a set of doll-house …

Visual Detection Of Cryptic Prey By Blue Jays (Cyanocitta Cristata), Alexandra T. Pietrewicz, Alan Kamil Jan 1977

Visual Detection Of Cryptic Prey By Blue Jays (Cyanocitta Cristata), Alexandra T. Pietrewicz, Alan Kamil

Avian Cognition Papers

Blue jays learned to respond differentially to the presence or absence of Catocala moths in slides. This detection of the moths by the jays was affected by the background upon which the moth was placed and its body orientation, thus providing an objective measure of crypticity. These procedures are useful for the study of visual detection of prey.

Societal Complexity And Moral Development: A Kenyan Study., Carolyn P. Edwards Jan 1975

Societal Complexity And Moral Development: A Kenyan Study., Carolyn P. Edwards

Department of Psychology: Faculty Publications

This study examines the moral judgment levels (as measured by Kohlberg’s 6-stage moral judgment interview) for two Kenyan samples. The first sample includes a culturally and racially group of 35 young men and 17 women studying at the University of Nairobi, while the second sample consists of 44 males and 14 females living in seven communities in the Central and Western Provinces of Kenya who were interviewed by a cadre of trained University students on their school vacation. The moral judgment interview included four hypothetical moral dilemmas and a standard set of probing questions. Three of the dilemmas were standard …

The Role Of Adventitious Reinforcement In Operant Discrimination, Alan Kamil, John W. Davenport Jan 1968

The Role Of Adventitious Reinforcement In Operant Discrimination, Alan Kamil, John W. Davenport

Avian Cognition Papers

Rats were trained in 2 SD-SΔ discrimination experiments in which the effects of an SD-postponement contingency during SΔ and temporal regularity of SΔ duration were assessed. Experiment I showed that discrimination is markedly facilitated by the presence of an SD-postponement contingency of either fixed or variable duration. Experiment II showed that variable-duration SΔ periods in a noncontingent schedule can also greatly enhance formation of an operant discrimination. These effects were attributed to differences in the probability of adventitious reinforcement of SΔ behavior by SD events.
