Multimodal access to verbal name codes

Congruent information conveyed over different sensory modalities often facilitates a variety of cognitive processes, including speech perception (Sumby & Pollack, 1954). Since auditory processing is substantially faster than visual processing, auditory-visual integration can occur over a surprisingly wide temporal window (Stein, 1998). We investigated the processing architecture mediating the integration of acoustic digit names with corresponding symbolic visual forms. The digits "1" or "2" were presented in auditory, visual, or bimodal format at several stimulus onset asynchronies (SOAs; 0, 75, 150, and 225 msec). The reaction times (RTs) for echoing unimodal auditory stimuli were approximately 100 msec faster than the RTs for naming their visual forms. Correspondingly, bimodal facilitation violated race model predictions, but only at SOA values greater than 75 msec. These results indicate that the acoustic and visual information are pooled prior to verbal response programming. However, full expression of this bimodal summation is dependent on the central coincidence of the visual and auditory inputs. These results are considered in the context of studies demonstrating multimodal activation of regions involved in speech production.     

Cross-cultural validity of the developmental test of visual-motor integration

For 28 mildly handicapped Japanese students visual-motor integration scores were significantly correlated with both mathematics and reading scores, which substantiates the test's cross-cultural validity. Although slightly larger correlations with mathematics achievement than with reading achievement were noted in both cultures, the differences between reading and mathematics correlations were not significant for Japanese children. In contrast, in at least one American study the correlation between the visual-motor integration scores and mathematics achievement was significantly greater than that between the test and reading achievement. It is clear that further research with larger samples for both American and Japanese groups is essential.     

Physical cues of ovulatory status: A failure to replicate enhanced facial attractiveness and reduced waist-to-hip ratio at high fertility

We investigated women's facial attractiveness and body shape as a function of menstrual cycle phase, with the expectation from previous research that both would be enhanced during the high fertile phase. To control for the effects of women's daily behaviors on their appearance and waistline, we visited 37 normally cycling women twice in their dorm, where we photographed and measured them at low and high fertile days of their cycle immediately upon their waking. Seventy-four judges from a separate institution chose, for each woman, the picture they thought was more attractive. We analyzed a subset of 20 women who, by forward counting, had a High Fertility visit between Days 10-13 and a Low Fertility visit between Days 20-23; and we also analyzed a subsample of 17 women who, by reverse counting, had a High Fertility visit on the days leading to ovulation and a Low Fertility visit one week after ovulation. In neither set of analyses were women's waist- to-hip ratios lower nearer ovulation, and in neither set were women's high fertile pictures chosen at an above-chance rate by either male or female judges. We did not find evidence that facial attractiveness and waist-to-hip ratio are reliable physical cues of ovulatory status.     

Investigative psychology and law: towards collaboration by focusing on evidence and inferential reasoning

Introducing a special issue of this journal, Youngs discussed the desirability of, but problems in realising, greater collaboration between psychology and the criminal investigation and trial processes. This paper acknowledges the value of investigative psychology's potential contribution but argues that the alleged incompatibilities, between psychology and law, are based upon too narrow a conception of law and legal action. A direct approach, with considerable potential for productive, principled, and practical research, already exists. It involves focusing on the evidence, assessing it along each of its three credentials, and identifying the nature of the inferential reasoning involved. This paper identifies a number of ways in which practical, inter‐disciplinary and collaboration could and should be developed to ensure that the courts receive quality evidence. It also argues that more attention should be paid to abductive inferential reasoning, both by researchers and courts. Copyright © 2011 John Wiley & Sons, Ltd.     

Conceptualizing the Prospective Relationship Between Social Support,Stress, and Depressive Symptoms Among Adolescents

The goal of the current study is to examine the relationship amongst social support, stress, and depressive symptoms within a transactional and diathesis-stress framework using a multi-wave, longitudinal design. At the initial assessment, adolescents (n = 258) completed self-report measures assessing social support (peer, classmate, parent, and total), dependent interpersonal stress, anxious symptoms, and depressive symptoms. Additionally, participants reported stress and symptomology in each of the four waves spanning six months. Results of time-lagged, idiographic, multilevel modeling indicated that stress mediated the relationship between lower parental, classmate, and total social support and subsequent depressive, but not anxious, symptoms. In contrast, lower levels of peer support were not associated with higher levels of stress and subsequent depressive symptoms. Additionally, only classmate support deficits significantly moderated the relationship between stress and depressive symptoms. Overall, the results suggest that deficits in parental and classmate support may play a greater role in contributing to adolescent depression as compared to deficits in peer support.     

Do I want to know? How the motivation to acquire relationship-threatening information in groups contributes to paranoid thought,suspicion behavior,and social rejection

We investigated the psychological and social consequences associated with individuals’ motivation to search for information about whether they have been indirectly harmed by members of their group. Consistent with a motivated social cognition perspective, group members who were either chronically (Study 1a) or temporally (Study 1b) high in the motivation to acquire relationship-threatening information (MARTI) made more sinister attributions in ambiguous situations and entertained more paranoid cognitions about their coworkers. Moreover, paranoid cognitions about coworkers mediated the relationship between MARTI and suspicion behaviors toward coworkers (Study 2). Consistent with a social interactionist perspective, others chose to exclude prospective group members who were high in MARTI from joining the group and planned to reject them if they became group members (Study 3). Others’ social rejection of the focal group member was predicted by their anger toward group members who were high in MARTI (Study 4).     

Likening stairs in buildings to climbing a mountain: Self-reports of expected effects on stair climbing and objective measures of effectiveness

Objectives

Health promotion agencies advocate use of mountain climbing goals to encourage regular stair climbing, a current public health target. This paper tests effects of a mountain climbing campaign on objective measures of stair use for the first time.

Design

Field interview and quasi-experimental, interrupted time-series study.

Method

In field interviews, a convenience sample (n = 1350) responded to questions about different goals, i.e., heights of climb, to encourage stair use in buildings. Subsequently, a point-of-choice intervention with the main message ‘Take the stairs to the top of this building once a day and in a year, you would have climbed Mount Everest almost twice’ was tested in a 12-floor worksite. A no-message baseline was followed by installation of the intervention.

Results

Stair ascent (n = 62,716) and descent (n = 61,218) at the ground floor was measured with automated counters at baseline (11 days) and during the intervention (18 days). The majority of interviewees (60%) chose a message based on climbing Mt. Everest as the most motivating, with only 5% of interviewees not motivated by any climbing goal. Nonetheless, the subsequent intervention using the mountain climbing goal had no effect on stair climbing (OR = 0.96). As the campaign specifically targeted stair ascent, it failed to influence the behaviour with the greater public health dividend.

Conclusion

The discrepancy between pre-testing and the campaign may reflect the fact that performance goals can only be achieved at the end of the task and may not be continually rewarded during accumulation of behaviour towards the goal.
