Measuring socioeconomic status: reliability and preliminary validity for different approaches

This study investigated issues related to commonly used socioeconomic status (SES) measures in 140 participants from three cities (Atlanta, Boston, and Toronto) in two countries (United States and Canada). Measures of SES were two from the United States (four-factor Hollingshead scale, Nakao and Treas scale) and one from Canada (Blishen, Carroll, and Moore scale). Reliability was examined both within (interrater agreement) and across (intermeasure agreement) measures. Interrater reliability and classification agreement was high for the total sample (ranger = .86 to .91), as were intermeasure correlations and classification agreement (range r = .81 to .88). The weakest agreement across measures was found when families had one wage earner who was female. Validity data for these SES measures with academic and intellectual measures also were obtained. Some support for a simplified approach to measuring SES was found. Implications of these findings for the use of SES in social and behavioral science research are discussed.     

Development of Body Modification and Excessive Exercise Scales for adolescents

The present study was designed to develop a Body Modification Scale (BMS) to measure body change among adolescents and to modify an Excessive Exercise Scale (EES) into a shorter form for adolescents. Two hundred and twenty-one girls and 192 boys from Grades 7 to 10 completed the BMS and the EES. Factor analysis revealed three identical factors for the BMS for girls and boys: weight loss, weight gain, and muscle mass. Two identical factors for girls and boys were also revealed for the EES. Both factor structures were further validated on a separate sample of 286 adolescents (140 girls, 146 boys). The BMS and EES demonstrated excellent reliability (alpha > .86) and high test-retest reliability (alpha > .82) over 1 month. Good concurrent validity was also found for the weight loss factor of the BMS. These findings demonstrate the utility of these two scales for use with adolescents.     

Speaking for Ourselves: Feminist Methods and Community Psychology

Although feminist and community psychology share a number of epistemological and methodological perspectives that guide their respective theories and research practices, it has been argued that community psychology has not fully integrated a feminist perspective into the discipline. This paper examines how community psychology and feminist research methods might combine to help us better understand women's experiences without essentializing or universalizing those experiences. The authors offer a series of suggested directions for feminist research that may also prove promising for community psychology. Particular attention is paid to feminist social constructionist approaches insofar as they address the complex relationship between epistemology and methodology.     

Line spacing in Mondrian paintings and computer-generated modifications

Students compared computer-generated pictures of which 1 had line spacing and orientation proportional to that in a Mondrian picture (Mondrian-like), and 9 had divergent line spacing (divergently spaced). Preference was above average for the Mondrian-like picture compared with that for the divergently spaced pictures. However, participants did not prefer the Mondrian-like picture to divergently spaced pictures that were preselected as aesthetically pleasing by other participants. The results of the present experiments suggest that a computer algorithm can be developed to modify a picture in a way that is comparable with the way in which humans modify a picture to obtain a preferred picture. If aesthetic appeal is used in the storage and retrieval of visual information, then the algorithm could provide a better understanding of human perceptual processes. The results are related to consistency of aesthetic judgments across participants, levels of processing, and apparent contrast effects.     

Idiom comprehension deficits in relation to corpus callosum agenesis and hypoplasia in children with spina bifida meningomyelocele

Idioms are phrases with figurative meanings that are not directly derived from the literal meanings of the words in the phrase. Idiom comprehension varies with: literality, whether the idiom is literally plausible; compositionality, whether individual words contribute to a figurative meaning; and contextual bias. We studied idiom comprehension in children with spina bifida meningomyelocele (SBM), a neurodevelopmental disorder associated with problems in discourse comprehension and agenesis and hypoplasia of the corpus callosum. Compared to age peers, children with SBM understood decomposable idioms (which are processed more like literal language) but not non-decomposable idioms (which require contextual analyses for acquisition). The impairment in non-decomposable idioms was related to congenital agenesis of the corpus callosum, which suggests that the consequences of impaired interhemispheric communication, whether congenital or acquired in adulthood, are borne more by configurational than by compositional language.     

Victim and perpetrator accounts of interpersonal transgressions: self-serving or relationship-serving biases?

Two studies investigated perpetrator and victim biases in reported transgressions. Study 1 showed that in nonromantic relationships, perpetrators were more likely than victims to emphasize details that minimized their transgressions, whereas victims were more likely to exaggerate the severity of the event. Study 2 examined these perspective-related differences in romantic relationships and their relationship to forgiveness. Although victims were less likely than perpetrators to include features that minimized the event, they were no more likely to include features that magnified the event; individuals in highly satisfying relationships were less likely to exhibit self-serving biases than were individuals in less satisfying relationships. The data also were consistent with a causal sequence in which positive relationship quality led to more benign interpretations of a transgression, which in turn, promoted forgiveness.     

Punctuated Equilibrium,Moral Panics and the Ethics Review Process

A review of the literature and ethnographic data from Australia, Canada, New Zealand, the United States, and the United Kingdom on the research ethics review process suggest that moral panics can become triggers for punctuated equilibrium in the review process at both the macro and microlevel, albeit with significantly different levels of magnitude and impact. These data suggest that neither the development of the ethics review process nor the process itself proceeds gradually, but both are characterized by periodic major shifts evoked by particular events or situations that result in varying levels of moral panic. One way to deal with this moral panic is to increase the regulation of research and the depth or intensity of the scrutiny of applications under ethics review. Moral panics at the macrolevel influence those at the microlevel and, if the moral panic evoked at the local or microlevel is not satisfactorily resolved, it will evoke action at a higher level. Understanding the evolution of research ethics review processes from this perspective might help make actions by ethics committees and policy makers more understandable and help explain why attention to research ethics are heightened at particular points in time. It may also provide a basis for developing recommendations for adaptations to the ethics review process and policy at both the local and macrolevel.     

A prototype analysis of forgiveness

Many definitions of forgiveness currently exist in the literature. The current research adds to this discussion by utilizing a prototype approach to examine lay conceptions of forgiveness. A prototype approach involves categorizing objects or events in terms of their similarity to a good example, whereas a classical approach requires that there are essential elements that must be present. In Study 1, participants listed the features of forgiveness. Study 2 obtained centrality ratings for these features. In Studies 3 and 4, central features were found to be more salient in memory than peripheral features. Study 5 showed that feature centrality influenced participants' ratings of victims involved in hypothetical transgressions. Thus, the two criteria for demonstrating prototype structure (that participants find it meaningful to judge features in terms of their centrality and that centrality affects cognition) were met.
