Aging and the structure and long-term stability of the internalizing spectrum of personality and psychopathology

Structural psychopathology research has identified two broad factors--internalizing and externalizing--that account for comorbidity among many common mental disorders. Evaluating the utility of these factors for nosology, research, and treatment entails expanding beyond a cross-sectional understanding to how these factors evolve over time. We tested factorial invariance of internalizing in three age cohort groups--35 years and under (n = 1,729), 36-50 years (n = 2,719), and over 50 years (n = 2,601)--as well as the long-term stability of internalizing within individuals. Internalizing showed a notable degree of invariance between cohorts and within cohorts over time; long-term internalizing stability was equivalently moderate-to-high in each cohort.     

Methods of Cheating and Deterrents to Classroom Cheating: An International Study

This study examines the methods students use to cheat on class examinations and suggests ways of deterring using an international sample from Australia, China, Ireland, and the United States. We also examine the level of cheating and reasons for cheating that prior research has highlighted as a method of demonstrating that our sample is equivalent to those in prior studies. Our results confirm the results of prior research that primarily employs students from the United States. The data indicate that actions such as having multiple versions of the examination and scrambling the questions on these versions would deter cheating. In addition, given the increased level of cheating and students' increased perception of the social acceptability of cheating in college, the data provided by our international sample also suggest that some relatively simple precautions by instructors could dramatically reduce the level of cheating on in-class examinations.     

The Application of Biological, Evolutionary, and Sociocultural Frameworks to Issues of Gender in Introductory Psychology Textbooks

The purpose of this paper is to explore the application of biological, evolutionary, and sociocultural frameworks to issues of gender in the 10 most popular introductory psychology textbooks in the U.S. The use of these metatheories is of interest to feminist scholars because they have implications for the extent to which students learn that gender and gender differences are fixed and innate or socially constructed. If gender and gender differences are seen as malleable, then efforts at social change to improve women’s status or men’s and women’s abilities or opportunities can be understood as promising endeavors. The relative use of these three frameworks differed dramatically across books, affording all scholars the opportunity to actively select those texts whose prominent frameworks best align with their course goals. The paper concludes with suggestions for which books offer the most thorough coverage of sociocultural frameworks.     

The mediating role of perceptual validation in the repentance-forgiveness process

This research focuses on one potential mechanism by which repentance leads to forgiveness. Two studies demonstrate that repentance leads to increased perceptual validation (social verification that one is correct about one's interpretation of an event) and, ultimately, more forgiveness. Participants reported more perceptual validation when they received repentance than when they did not (Studies 1 and 2), particularly repentance that included an acknowledgement of the transgression and the harm done (Study 2). In addition, in Study 2, acknowledgement of the transgression by a third party also had a positive effect on forgiveness. There was evidence that perceptual validation mediated the repentance-forgiveness relationship. These findings suggest that repentance facilitates forgiveness, at least in part, because it makes victims feel validated.     

A fully automated two-way locomotor training apparatus

A fully automated two-way locomotor training apparatus is described. The device employs two bilevel chambers that are separated by a length of straight alley. The rat is dropped from the distinctively cued upper level of one chamber onto the grid floor of its lower level. To escape shock, the rat must leave this lower level, traverse the alley segment, and jump into the upper level of the opposite compartment. Although the animal is required to traverse the same alley in two directions, its terminal response always carries it into a distinctive goal region where shock never occurs. A brief experiment is described that was designed to assess the effectiveness of this device in the acquisition and extinction of a locomotor escape response with rats.
