Development and Assessment of Short and Very Short Forms of the Infant Behavior Questionnaire–Revised

Using data from parents of 761 infants from 6 independent samples, short (91 items, 14 scales) and very short (37 items, 3 broad scales) forms of the Infant Behavior Questionnaire–Revised (IBQ–R), a well-established caregiver report measure of temperament for infants aged 3 to 12 months, were developed. The forms were subsequently evaluated with data from 1,619 participants from 11 samples. Over 90% of Cronbach's alphas and part–whole correlations calculated for the short and very short form scales were greater than.70. Interparent agreement was nearly identical to that obtained with standard IBQ–R scales, averaging.41 and ranging from.06 to.76. Longitudinal stability over multiple time spans, and estimated retest reliability of the short form scales, were highly similar to those of standard forms, with estimated retest reliability averaging.72 and ranging from.54 to.93. Convergent and predictive validity of select short form scales were comparable to, but slightly lower, than those observed for standard IBQ–R scales. Recommendations for the use of the standard, short, and very short scales are discussed.     

Normal Functioning and the Treatment/Enhancement Distinction: An Opportunity Based Assessment

As genome mapping technology uncovers the roots of pathologic and physiologic human functioning, important questions are brought to the fore concerning our conceptualization of ideas such as disease, treatment, and enhancement. In 1985, Norman Daniels proposed a normal-functioning model that expands John Rawls’ theory of justice to obligate the provision of health care based on the constraints disease places on individual opportunity, but also limits the commitment of the medical establishment by focusing on states that represent deviations from normal human function. While some argue that the boundaries of medical institutions’ commitment to provide services within a normal-functioning model are arbitrary, the degree to which these concerns truly threaten the framework is often exaggerated in special cases put forward in the literature. Furthermore, the normal-functioning model provides a comprehensive basis for agreement in discussions of medicine’s commitment to the demands of social justice where resources are limited and avoids the dangerous overextension of the healthcare system and medicalization to which more expansive models are exposed.     

Between-list lag effects in recall depend on retention interval

Although the benefits of spaced retrieval for long-term retention are well established, the majority of this work has involved spacing over relatively short intervals (on the order of seconds or minutes). In the present experiments, we evaluated the effectiveness of spaced retrieval across relatively short intervals (within a single session), as compared to longer intervals (between sessions spaced a day apart), for long-term retention (i.e., one day or one week). Across a series of seven experiments, participants (N = 536) learned paired associates to a criterion of 70 % accuracy and then received one test–feedback trial for each item. The test–feedback trial occurred within 10 min of reaching criterion (short lag) or one day later (long lag). Then, a final test occurred one day (Exps. 1–3) or one week (Exps. 4 and 5) after the test–feedback trial. Across the different materials and methods in Experiments 1–3, we found little benefit for the long-lag relative to the short-lag schedule in final recall performance—that is, no lag effect—but large effects on the retention of information from the test–feedback to the final test phase. The results from the experiments with the one-week retention interval (Exps. 4 and 5) indicated a benefit of the long-lag schedule on final recall performance (a lag effect), as well as on retention. This research shows that even when the benefits of lag are eliminated at a (relatively long) one-day retention interval, the lag effect reemerges after a one-week retention interval. The results are interpreted within an extension of the bifurcation model to the spacing effect.     

Progress Toward Understanding the Structure and Determinants of Job Performance: A focus on task and citizenship performance

Job performance criterion models have become more popular and more often investigated. The current research adds to this literature by testing performance models focusing on ability and personality predictors of task and citizenship job performance. Air traffic controllers (N = 928) completed cognitive ability and personality predictor measures, were administered a performance test assessing two possible mediators, and were evaluated using supervisor and peer ratings of two task performance, one citizenship performance, and an overall performance dimension. Path analyses largely confirmed that ability predicts primarily task performance and personality predicts primarily citizenship performance. The mediation related to task knowledge and skill on the task performance side was confirmed, and the overall fit of the performance models was quite good. Discussion focuses on how the present research furthers progress toward mapping relations among individual differences and individual performance constructs, beyond using overall performance as the endogenous performance variable.     

Why Should Nanoscience Students be Taught to be Ethically Competent?

During the education of scientists at the university level the students become more and more specialized. The specialization of the students is a consequence of the scientific research becoming specialized as well. In the interdisciplinary field of nanoscience the importance of specialization is also emphasized throughout the education. Being an interdisciplinary field of study the specialization in this area is not focused on scientific disciplines, but on the different branches of the research. Historically ethics has not been a priority in science education, however, in recent years the importance of such teachings has been highly recognize especially in medicine, biotechnology and engineering. The rapid development, the many new and unknown areas and the highly specialized focus of nanotechnology suggest the importance of having ethically competent researchers. In this article the importance of ethical competence in nanoscience research is argued for by an example of a dilemma that could occur in a research project. The dilemma is analyzed using two different ethical views, generating two different choices for action. It is seen that the dilemma can have more than one solution and that ethical competence can help in justifying the choice of solution in a specific situation. Furthermore it is suggested that a way to reach this competence is through education in ethics incorporated into the nanoscience education curriculum.     

Display-wide influences on figure–ground perception: The case of symmetry

Past research has demonstrated that convex regions are increasingly likely to be perceived as figures as the number of alternating convex and concave regions in test displays increases. This region-number effect depends on both a small preexisting preference for convex over concave objects and the presence of scene characteristics (i.e., uniform fill) that allow the integration of the concave regions into a background object/surface. These factors work together to enable the percept of convex objects in front of a background. We investigated whether region-number effects generalize to another property, symmetry, whose effectiveness as a figure property has been debated. Observers reported which regions they perceived as figures in black-and-white displays with alternating symmetric/asymmetric regions. In Experiments 1 and 2, the displays had articulated outer borders that preserved the symmetry/asymmetry of the outermost regions. Region-number effects were not observed, although symmetric regions were perceived as figures more often than chance. We hypothesized that the articulated outer borders prevented fitting a background interpretation to the asymmetric regions. In Experiment 3, we used straight-edge framelike outer borders and observed region-number effects for symmetry equivalent to those observed for convexity. These results (1) show that display-wide information affects figure assignment at a border, (2) extend the evidence indicating that the ability to fit background as well as foreground interpretations is critical in figure assignment, (3) reveal that symmetry and convexity are equally effective figure cues and, (4) demonstrate that symmetry serves as a figural property only when it is close to fixation.     

Learning Disabilities and Delinquent Behaviors among Adolescents: A Comparison of Those with and without Comorbidity

Research is inconclusive on whether adolescents with learning disabilities (LD) engage in more delinquency than adolescents without such deficits. Mixed results may result from a failure to account for the effects of co-occurring disabilities. Using the National Longitudinal Study of Adolescent Health, this study examines delinquency among adolescents without disabilities to youth with LD, Attention Disorder Symptoms (ADS), and comorbid LD/ADS. Results indicate no significant differences in property offenses, or alcohol, tobacco, and marijuana use; however, youth with LD reported significantly more violence than non-disabled youth. Findings illustrate the heterogeneous effects various disabilities have on delinquent behavior. Future research and policy implications will be discussed.     

The Role of Positive Emotions in Reducing Depressive Symptoms Among Army Wives

The homecoming period following combat deployment can be as stressful to military spouses as the deployment itself. This study used the broaden-and-build theory of positive emotions to examine whether personal resources (adaptive coping, maladaptive coping, and resilience) mediate the relationship between positive emotions and depressive symptoms in Army wives (N = 252) following the homecoming of a deployed active-duty service member. Using path analysis, after controlling for demographic variables and marital satisfaction, positive emotions were related to all 3 personal resources (positively to adaptive coping and resilience, negatively to maladaptive coping). In turn, adaptive coping and resilience were related to fewer depressive symptoms and maladaptive coping to greater depressive symptoms. The direct path between positive emotions and depressive symptoms was nonsignificant, suggesting complete mediation. The final model accounted for 54% of the total variance in depressive symptoms. Results support the important role that positive emotions play in decreasing depressive symptoms in this high-risk population.
