There is much debate as to the extent and nature of functional specialization within the different subregions of the prefrontal cortex. The current study was undertaken to investigate the effect of damage to medial prefrontal cortex subregions in the rat. Rats were trained on two biconditional discrimination tasks, one auditory and one visual, in…

This article extends Simpson's (2003) research on sex differences in social dilemmas. To test the hypotheses that men defect in response to greed and women to fear, Simpson created Fear and Greed Dilemmas, but experiments using these games supported the greed hypothesis only. In this article I focus on why the fear hypothesis failed and suggest…

The colourful, vigorous territorial display behaviour of the Siamese fighting fish, "Betta splendens", has great appeal for both pet enthusiasts and animal behaviourists. Their beauty, longevity, easy maintenance and rearing make them a popular pet and an ideal science laboratory specimen. This investigation utilises "B. splendens" to test for the…

Studies have suggested attention-free semantic processing of natural scenes in which concurrent tasks leave category detection unimpaired (e.g., F. Li, R. VanRullen, C. Koch, & P. Perona, 2002). Could this ability reflect detection of disjunctive feature sets rather than high-level binding? Participants detected an animal target in a rapid serial…

In recent years, several investigators have examined trends in the antecedent research literature through discussion of key conceptual models considered to guide this research (Conroy & Stichter, 2003; Smith & Iwata, 1997; Smith, Iwata, & Michael, 2000) as well as related trends in measurement (Mahon, Shores, & Buske, 1999). Despite varied points…

The use of mathematical models in the experimental analysis of behavior has increased over the years, and they offer several advantages. Mathematical models require theorists to be precise and unambiguous, often allowing comparisons of competing theories that sound similar when stated in words. Sometimes different mathematical models may make…

Citation analyses were carried out on master's theses in three disciplines: forensic psychology, forensic science, and criminal justice, completed and deposited in the John Jay College Library from 1991 to 2004. The aim was to determine the effect of availability of electronic journals on students' choice of references. The number of journal…

Teaching social skills to students with emotional and behavioral disorders (EBD) has become an accepted practice. Literally hundreds of social skills training (SST) efficacy studies for students with EBD appear in the literature. As a result, many authors have published both narrative and meta-analytic reviews of the literature. Reviews have…

This paper reviews a number of studies that have tested Fiedler's (1964) Contingency Model and Least Preferred Co-Worker Scale of leadership style and effectiveness, focusing on studies that have examined the characteristics and stability of this scale across age, ethnicity, and gender. The Contingency Model is based on three determinants of…

Data gleaned from the 1982, 1985, and 1992 Surveys of Public Participation in the Arts (SPPAs) were used in this analysis of participation in opera and musical theater/operetta. Findings indicate that opera is the least popular of the fine arts, being the least frequented and the least selected as an activity respondents would like to attend more…

This paper is intended to assist people who work with persons having mental retardation to better understand what life is like for these individuals. The recommended training program is based on a case study approach, with guided experiences in small study groups led by trained leaders. Principles of training for group leaders are identified,…

The four studies presented show how expertise, from the cultural-historical theory of activity, is constructed interactively in everyday problem situations. They also demonstrate that purely situational analyses of discourse are insufficient as attempts to explain expertise. The four studies are presented as individual chapters: (1) Expertise as…

A study investigated the cognitive and grammatical activities carried out during writing by 22 incoming freshmen and 20 upperclass college students. It was hypothesized that the upperclassmen's compositions would be judged better in quality than those of the freshmen, and that the upperclassmen would show fewer pauses in which they were…

An approach to classifying the subject matter of higher education is discussed. It is suggested that higher education is primarily a behavioral phenomenon, although it contains nonbehavioral elements, and it should be studied by other disciplines in addition to the behavioral sciences. To study higher education is to study behavioral patterns such…

Methodologies for life course analyses must explain complex biological, psychosocial, and social factors which result in various patterns of life trajectories. Four problems are characteristic of current research: a seemingly endless list of potentially significant variables; a dearth of life course theory beyond childhood to assist in targeting…
