Short-term memory scanning viewed as exemplar-based categorization

Exemplar-similarity models such as the exemplar-based random walk (EBRW) model (Nosofsky & Palmeri, 1997b) were designed to provide a formal account of multidimensional classification choice probabilities and response times (RTs). At the same time, a recurring theme has been to use exemplar models to account for old-new item recognition and to explain relations between classification and recognition. However, a major gap in research is that the models have not been tested on their ability to provide a theoretical account of RTs and other aspects of performance in the classic Sternberg (1966) short-term memory-scanning paradigm, perhaps the most venerable of all recognition-RT tasks. The present research fills that gap by demonstrating that the EBRW model accounts in natural fashion for a wide variety of phenomena involving diverse forms of short-term memory scanning. The upshot is that similar cognitive operating principles may underlie the domains of multidimensional classification and short-term old-new recognition.     

Mesomorphy correlates with experiential cognitive style

The purpose of this study was to test for a relationship between mesomorphy and experiential cognitive style (S. Epstein, 1994) in a sample of university students (30 women and 24 men). Anthropometric somatotypes were obtained using the Heath-Carter procedure (J. E. L. Carter, 2002). Experiential cognitive style was operationalized as scores on the experiential scale of the Rational Experiential Inventory for Adolescents (A. D. Marks, D. W. Hine, R. L. Blore, & W. J. Phillips, 2008). Nonparametric bootstrap correlations were calculated using 80% confidence intervals. There were significant correlations between mesomorphy and experiential cognitive style for men (r(s) = .33) and women (r(s) = .25). For men, experiential cognitive style was also correlated with endomorphy (r(s) = .39) and ectomorphy (rs = -.48).     

The costs and benefits of testing text materials

Tests have been shown to improve the later recall of tested information, a result known as the testing effect. Tests, however, can also impair the later recall of related information, an effect known as retrieval-induced forgetting. Although retrieval-induced forgetting has been demonstrated using a wide variety of materials, recent work suggests that learning information in the context of a coherent text passage may afford protection from retrieval-induced forgetting. In four experiments we explored the conditions under which retrieval-induced forgetting does and does not occur with such materials. We found that two factors-the coherence of the to-be-learned material and the competitiveness of retrieval practice-are important in determining whether retrieval-induced forgetting does or does not occur. Furthermore, even if retrieval-induced forgetting does occur, having the opportunity to restudy the forgotten information can prevent that forgetting from persisting. Taken together, these findings provide greater understanding of the costs and benefits of testing text materials, with possible implications for the optimisation of testing as a tool for learning in educational contexts.     

Integrating social knowledge and physical cues when judging the attractiveness of potential mates

Although many women find masculine men physically attractive, the perception that such men are prone to infidelity may limit their appeal as romantic partners. To explore this issue, we first investigated the interplay between the effects of men's face shape (masculinity versus femininity) and social knowledge of men's behavior in previous romantic relationships (faithful versus unfaithful) on women's judgments of men's attractiveness. Analyses suggested that the extent to which women rated masculine men to be more attractive than feminine men was significantly greater when judging men labeled as faithful than when judging men labeled as unfaithful. In a second experiment, we obtained similar results when the women in our study were instructed to imagine they were on a date with each of the men and that, while on the date, they observed him either flirting or not flirting with another woman. These interactions suggest that social knowledge about men's behavior in romantic relationships can offset one of the costs that women associate with choosing a masculine mate, increasing the appeal of masculine men. More fundamentally, these findings suggest integration of social knowledge and information from facial cues in women's attractiveness judgments.     

Effects of moral reconation therapy upon moral reasoning, life purpose, and recidivism among drug and alcohol offenders

40 incarcerated DWI offenders and 62 drug offenders who were treated with Moral Reconation Therapy were assessed with respect to levels of moral reasoning, their perceived purpose in life, and subsequent recidivism. Analysis showed that, as clients progress in the program, levels of moral reasoning and purpose in life increase significantly. Level of moral reasoning appears to increase with clients' completion of therapeutic steps. Preliminary recidivism data on 103 male and female inmate-clients who have participated in an aftercare program using the therapy appear encouraging.     

Evaluation of subclinical depression in children using self-, peer-, and teacher-report measures

This study reports on several classification issues utilizing the Children's Depression Inventory (CDI), the Child Behavior Checklist-Teacher Form (CBCL-T), and the Peer Nomination Inventory of Depression (PNID). The first sample contained 752 public school children in grades 5, 6, and 9. A second sample of 142 fifth-graders was included to have an additional PNID comparison group. Results revealed moderate correlations between the CDI and the CBCL-T and PNID. Use of multiple criteria for selecting children as depressed was discussed, and selection rates using multiple measures with either strict or lenient cutoff scores were given. Normative data on the PNID were evaluated, and it was suggested that norms for the PNID may not be generalizable to other samples. Finally, race and gender analyses showed that CDI scores for females were significantly higher than for males, whereas CDI scores for Hispanics were significantly higher than for non-Hispanic whites. However, Omega-squared analyses for these two variables showed this to be of little practical significance.     

Inclusion: Considerations from social validity and Functional Outcome Analysis

Inclusion and particularly full inclusion has become a hotly debated topic. While proponents of inclusion believe that social, behavioral, academic, and developmental benefits occur for children with disabilities as well as for other, nondisabled, children in the classroom, research into inclusion provides equivocal results. This paper (a) describes inclusion, highlighting the inconsistencies in definitions and research; (b) discusses the importance of social validity in making inclusion decisions; and (c) presents an approach to inclusion using Functional Outcome Analysis (Noell & Gresham, 1993). While inclusion may be philosophically desirable, the research does not support its application as an all-inclusive approach. Inclusion decisions must be made on a case-by-case basis after a functional analysis of the student's behavior has been conducted.     

Procreative liberty, biological connections, and motherhood.

Given the complex and dramatic array of issues currently facing us in reproductive ethics, bioethicists working on the topic might be forgiven feelings of trepidation when they cast their minds toward the next century. Currently, technologies such as artificial insemination by donor (AID), once the source of intense controversy, are used on a routine basis; mainstream newspapers carry advertisements offering "excellent compensation" to ova "donors;" courts are arguing whether women who serve as gestational or "surrogate" mothers have any parental rights; and proposals resurface to jail pregnant women who take street drugs. Sorting out which developments are to be welcomed and which are to be resisted -- and why -- will require us not only to clarify some of our most basic value commitments, but also to reflect on our understanding of concepts, such as motherhood, that we previously had the luxury of thinking obvious. Let me highlight two issues I think we will be forced to confront as we try to navigate the ethics of reproduction into the twenty-first century -- namely, the value of biological connection and the meaning of motherhood.
