Does making a conversation asynchronous reduce the negative impact of phone call on driving?

Mobile phone use at the wheel has a proven negative impact on driving. This paper aims to assess whether using an answerphone instead of a normal phone reduces this negative impact. The answerphone makes communication asynchronous and splits it into three disconnected and successive phases: interaction with the voice interface, listening to the message and answering, which have been evaluated separately.The experiment was conducted on a fixed base simulator, with 30 participants (half male and female, aged from 18 to 50 years, driving at least 5000 km per year).The results show better scores for correct responses to stimuli for answerphone communications than for phone communications, although response times were higher in both communication conditions than in the driving alone condition. When the three phases of answerphone use were compared, interacting with the answerphone and listening to the message were found to be significantly less disturbing than answering, in terms of correct responses and response times.By making the conversation asynchronous, the answerphone avoids direct interaction between driver and caller. The fact that communication is under the driver’s control allows him/her to pace the interaction better. Lastly, splitting up the conversation into different phases decreases the overall task difficulty.     

Why not find out whether religious beliefs predict surgical outcomes? If they do, why not find out why? Reply to Freedland (2004).

In this reply to K. E. Freedland's (see record 2004-13299-002) comments on R. J. Contrada et al. (see record 2004-13299-001), it is shown that the statistical issues he raised, and his preferred interpretation of the findings, were adequately addressed in the original article. It is argued that methodological limitations also were fully characterized and do not differ in kind from those of biomedical studies. Other issues discussed include the merits of focusing on distal versus proximal causation, plausibility of explanatory mechanisms for health effects of religious involvement, and potential practical applications that do not require manipulation of religious involvement. The article is concluded by commenting on subtle aspects of discourse that may unnecessarily polarize discussions of possible physical health effects of religious involvement.     

Ethnic culture,religion, and the mental health of Slavic-American women

Findings of a comparative research study of women of different ethnic back-grounds suggest that the Slavic religioethnic culture acts to promote successful aging and stable mental health among women of Slavic heritage. Home and family structure, deep religiosity, and participation in church and community affiars provide function and meaningful purpose to life that tends to mitigate the losses inherent in the aging process.     

Bias and Accuracy of Children's Perceptions of Peer Acceptance: Prospective Associations with Depressive Symptoms

Are depressive symptoms in middle childhood associated with more or less realistic social self-perceptions? At the beginning and end of the school year, children in grades 3 through 5 (n=667) rated how much they liked their classmates, predicted the acceptance ratings they would receive from each of their classmates, and completed self-report measures of perceived acceptance and depressive symptoms. Accuracy of perceived acceptance was indexed by the mean difference between pairs of predicted and received ratings (absolute values). Standardized residual scores created by regressing self-reported perceived acceptance (either predicted ratings or children's responses to a questionnaire measure of perceived peer acceptance) onto peer acceptance ratings formed two measures of bias. Bi-directional associations were found for accuracy of perceived acceptance and depressive symptoms; inaccurate perceptions predicted increases in depressive symptoms and depressive symptoms predicted decreased accuracy. Neither measure of bias predicted changes in depressive symptoms. Depressive symptoms predicted increases in negatively biased perceptions as assessed via questionnaire.     

Sex differences in children's discrepant perceptions of peer acceptance

Sex differences in children's play patterns during middle childhood are thought to promote greater awareness of social acceptance among girls compared with boys. The present study posited that girls are more discerning of peer acceptance than are boys; however, these sex differences were predicted to vary depending on how discrepant perceptions were assessed (i.e., inaccuracy versus bias). Additional differences were expected if children perceived acceptance by same- versus opposite-sex peers. Participants were 912 third through fifth graders (420 girls and 492 boys). Consistent with predictions, boys were more inaccurate than girls, but only for perceived acceptance by same-sex peers. As expected, girls were more negatively biased than boys, but only for perceived acceptance by opposite-sex peers. Results did not support the hypothesis that boys have more positively biased perceptions of peer acceptance than girls. Overall, these findings raise important issues regarding the evaluation of children's discrepant self-perceptions of peer acceptance.     

Mothers of transgender youth experience stigma-by-association

The current research investigated whether mothers of transgender youth experience stigma-by-association. Mturk participants (N = 489) were randomly assigned to read a vignette about a family in which the social identity (transgender, gay/lesbian, cisgender/heterosexual control) and gender (girl, boy) of a child was manipulated, while all other information was held constant. Results revealed stigma targeting mothers as a function of children's social identity (but not gender), such that mothers of transgender girls and boys were viewed substantially more negatively than identical mothers of cisgender/heterosexual youth. Moreover, this stigma was particularly robust among politically conservative participants. In contrast, mothers of gay/lesbian youth did not encounter systematic stigma, though they were sometimes perceived more negatively than mothers of cisgender/heterosexual youth. Results provide novel experimental evidence of stigma-by-association targeting mothers of transgender youth and raise serious concerns about the treatment of parents who seek to affirm their transgender children.     

Enhancing spatial skills of preschoolers from under-resourced backgrounds: A comparison of digital app vs. concrete materials

Spatial skills support STEM learning and achievement. However, children from low-socioeconomic (SES) backgrounds typically lag behind their middle- and high-SES peers. We asked whether a digital educational app—designed to mirror an already successful, spatial assembly training program using concrete materials—would be as effective for facilitating spatial skills in under-resourced preschoolers as the concrete materials. Three-year-olds (N = 61) from under-resourced backgrounds were randomly assigned to a business-as-usual control group or to receive 5 weeks of spatial training using either concrete, tangible materials or a digital app on a tablet. The spatial puzzles used were an extension of items from the Test of Spatial Assembly (TOSA). Preschoolers were pretested and posttested on new two-dimensional (2D) TOSA trials. Results indicate that both concrete and digital spatial training increased performance on the 2D-TOSA compared to the control group. The two trainings did not statistically differ from one another suggesting that educational spatial apps may be one route to providing early foundational skills to children from under-resourced backgrounds.     

Relative performance and implicit incentives in the intergroup prisoner’s dilemma

This paper illustrates how the payoff matrices of the single group Prisoner’s Dilemma (PD) and the Intergroup Prisoner’s Dilemma (IPD) differentially reinforce cooperation when participants care about relative performance. Examples of particular payoff patterns and thought experiments using a computational simulation demonstrate that withholding cooperation is not always the dominant strategy in the IPD. In the intergroup structure, three conditions differentially reinforce cooperation. When competing groups have equal numbers of cooperators, withholding cooperation is always the dominant strategy just as in the single group structure. In contrast, when one group has more cooperators than the other group, cooperation by its members can dominate withholding cooperation by members of the other group. Thus, the relative advantage of one group over another increases the payoff for cooperation in some configurations of the IPD over the payoff in the PD. Relative payoff is thus an untheorized variable motivating cooperation in the IPD.
