Memory for Objects and Positions: Delayed Non-matching-to-sample in Storing and Non-storing Tits

An operant delayed-non-matching-to-sample task using computer-presented images was used to test memory for position and object (shape and colour) cues in four species of tit (Parus), two food-storing species (P. palustris and P. ater) and two non-storing species (P. major and P. caeruleus). Both storers and non-storers performed successfully at retention intervals as long as 100 sec on all trial types, and there were no significant differences in performance between the two groups on any of the trial types. Performance by both groups was highest on trials in which both object and position cues were available and poorest on trials when object cues only were relevant. These data do not provide support for the hypothesis that food storers have a better memory for spatial cues than do non-storers.     

A content analysis of the conversational behavior of accepted and rejected children

The present study was designed to assess whether the conversational behavior of children separated into accepted, rejected, and mixed-status dyads differed along the dimensions of listening to, paying attention to, and indicating interest in their dyadic partner. Conversations of 40 third-grade dyads were analyzed as they occurred in a 2- min waiting period and a 4- min conversation period. Seventeen categories of verbal behaviors that indexed these dimensions were used as content codes. Multivariate analyses of variance performed on the observational data yielded significant main effects for status, sex, and experimental condition. Results are interpreted in terms of previous social skills research, and suggestions for future research are offered.     

Consumer credit card use: the roles of creditor disclosure and anticipated emotion

In response to federal legislative reform aimed, in part, at reducing consumer bankruptcy filings, the authors conducted 2 experiments examining the role of affect in purchasing behavior. In Experiment 1, they examined consumer debtors, and in Experiment 2, they examined nondebtors. In both experiments, they investigated purchasing decisions made during a simulated online shopping trip, with some participants receiving standard disclosures of interest rates and money owed and with other participants receiving information under the new enhanced disclosure regulations. Results demonstrated support for the influence of anticipated affect in credit card use among both debtors and nondebtors and indicated that anticipated emotion may moderate the impact of the enhanced disclosure regulations.     

An integrative typology of personality assessment for aggression: implications for predicting counterproductive workplace behavior

This study presents an integrative typology of personality assessment for aggression. In this typology, self-report and conditional reasoning (L. R. James, 1998) methodologies are used to assess 2 separate, yet often congruent, components of aggressive personalities. Specifically, self-report is used to assess explicit components of aggressive tendencies, such as self-perceived aggression, whereas conditional reasoning is used to assess implicit components, in particular, the unconscious biases in reasoning that are used to justify aggressive acts. These 2 separate components are then integrated to form a new theoretical typology of personality assessment for aggression. Empirical tests of the typology were subsequently conducted using data gathered across 3 samples in laboratory and field settings and reveal that explicit and implicit components of aggression can interact in the prediction of counterproductive, deviant, and prosocial behaviors. These empirical tests also reveal that when either the self-report or conditional reasoning methodology is used in isolation, the resulting assessment of aggression may be incomplete. Implications for personnel selection, team composition, and executive coaching are discussed.     

Talking to primary care patients about weight: a study of GPs and practice nurses in the UK

Evidence-based guidance recommends that primary care health practitioners should deliver brief interventions to their patients to change behaviours to reduce overweight and obesity. This cross-sectional study investigates UK general practitioners' (GPs) and practice nurses' communication about overweight with their overweight and obese patients. Forty general practitioners and 47 practice nurses in two inner-London primary care organizations completed a questionnaire about past practice and concerns. When there was no identified medical problem, 38% of GPs and 14% of practice nurses reported raising the issue on less than 50% of occasions. Practice nurses were more likely than GPs to raise the issue of weight, both when there was no medical problem and when there was a medical problem. When they did raise the issue of overweight, only 9% did so in the context of presenting possible solutions to weight loss or in discussions about health promotion. Fifty two per cent of GPs and 28% of practice nurses had concerns about raising the issue of overweight; the most common being that patients would react emotionally to the message. These results suggest that there is considerable room for improvement in the frequency with which primary care practitioners address the questions of weight in their overweight patients, especially amongst doctors. Training to increase skills and confidence in communicating about weight is recommended.     

Determining risk in pediatric research with no prospect of direct benefit: time for a national consensus on the interpretation of federal regulations

United States federal regulations for pediatric research with no prospect of direct benefit restrict institutional review board (IRB) approval to procedures presenting: 1) no more than "minimal risk" ( section sign 45CFR46.404); or 2) no more than a "minor increase over minimal risk" if the research is commensurate with the subjects' previous or expected experiences and intended to gain vitally important information about the child's disorder or condition ( section sign 45CFR46.406) (DHHS 2001). During the 25 years since their adoption, these regulations have helped IRBs balance subject protections with the pursuit of scientific knowledge to advance children's welfare. At the same time, inconsistency in IRB application of these regulations to pediatric protocols has been widespread, in part because of the ambiguity of the regulatory language. During the past decade, three federally-charged committees have addressed these ambiguities: 1) the National Human Research Protections Advisory Committee (NHRPAC) (Washington, DC), 2) the Institute of Medicine (IOM) Committee on the Ethical Conduct of Clinical Research Involving Children (Washington, DC); and 3) the United States Department of Health and Human Services Secretary's Advisory Committee for Human Research Protections (SACHRP) (Washington, DC). The committees have reached similar conclusions on interpretation of language within regulations section sign section sign 45CFR46.404 and 406; these conclusions are remarkably consistent with recent international recommendations and those of the original National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research (1977) report from which current regulations are based. Drawing on the committees' public reports, this article identifies the ethical issues posed by ambiguities in regulatory language, summarizes the committees' deliberations, and calls for a national consensus on recommended criteria.     

Tactual and visual alphanumeric suffix effects

Two experiments tested the effects of suffixes on the recall of tactual and visual sequences of alphabetic characters presented at 19 letters per min. Scoring techniques allowed for the differentiation of losses of item and order information. In Experiment I performance decrements were found for both modalities, which were mainly caused by item loss at the more recent part of the serial position curve in the suffix conditions. In Experiment II, these effects were replicated and a non-alphabetic suffix led to greater decrements for both modalities than an alphabetical suffix. While a suffix effect based on the loss of item information is consistent with a sensory trace interpretation of the suffix effect, the presence of a visual suffix effect with slow stimulus presentation is not. Additionally, the greater effect of the non-alphanumeric suffix challenges attentional interpretations. Some possible explanations are proposed.
