Drivers’ attitudes toward imperfect distraction mitigation strategies

Studies were conducted to assess driver acceptance of and trust in distraction mitigation strategies. Previous studies have shown that in-vehicle tasks undermine driver safety, and that there is a need for strategies to reduce the effects of in-vehicle distractions. Trust and acceptance of such strategies strongly influence their effectiveness. Different strategies intended to reduce distraction were categorized in a taxonomy. Focus groups were conducted to help refine this taxonomy and explore driver acceptance issues related to these strategies. A driving simulator experiment was then conducted using two of the strategies: an advising strategy that warns drivers of potential dangers and a locking strategy that prevents the driver from continuing a distracting task. These strategies were presented to 16 middle-aged and 12 older drivers in two modes (auditory, visual) with two levels of adaptation (true, false). Older drivers accepted and trusted the strategies more than middle-aged drivers. Regardless of age, all drivers preferred strategies that provided alerts in a visual mode rather than an auditory mode. When the system falsely adapted to the road situation, trust in the strategies declined. The findings show that display modality has a strong effect on driver acceptance and trust, and that older drivers are more trusting and accepting of distraction mitigation technology even when it operates imperfectly.     

The Cultural Adaptation of the Youth Quality of Life Instrument-Research Version for Latino Children and Adolescents

We reviewed the Spanish translation of the Youth Quality of Life Instrument-Research Version (YQOL-R) and culturally adapted the measure with Puerto Rican and Mexican American children and adolescents. The YQOL-R is a self-reported measure that includes four domains: Sense of Self, Social Relationships, Environment, and General Quality of Life. A total of 10 focus groups were conducted with children aged 9 to 11, adolescents aged 12 to 17, their parents, and mental health providers. Five focus groups were conducted in San Diego, California and five in San Juan, Puerto Rico. Eligible participants were recruited from children’s outpatient psychiatry clinics. We followed an iterative and recursive process in reviewing changes and modifications to the instrument using a bilingual committee and a Multi National Bilingual Committee. Greater semantic, content, and technical equivalence of the Spanish and English versions for the YQOL-R was achieved for the two largest U.S. Latino subgroups: Mexican Americans and Puerto Ricans. The cultural adaptation process revealed several important issues regarding the measurement of quality of life in different age groups. Additional items for school, relationships (both family and friends) and spare time suggested the need for a future children’s version of the instrument. For the adolescents, additional items were suggested in the areas of sexuality, intergenerational conflict and acculturative stress.

THE INTERTWINED ROLES OF GENES AND CULTURE IN HUMAN EVOLUTION

This essay critiques dual-inheritance theory as presented in Peter Richerson and Robert Boyd's book Not by Genes Alone: How Culture Transformed Human Evolution (2005). The theory states that culture became prominent in human evolution because it allowed relatively rapid adaptation to changing environments by means of imitation. Imitating the behavior of other members of one's community produces adaptive behaviors more readily than either genetic evolution or individual learning. Imitation follows a number of patterns: imitating high-status individuals, imitating the most common forms of behavior, imitating behaviors perceived to be the most effective solutions to various problems relevant to survival. This process combined with occasional innovations in behavior lead to a process of cultural evolution involving populations of cultural variants. Different local human populations were associated with different local populations of cultural variants, and both the human and the cultural populations evolved over time. Human evolution cannot be understood without taking into account these parallel processes of genetic and cultural evolution. Not by Genes Alone traces the implication of dual-inheritance theory for understanding human evolution and refers to various bodies of evidence relevant to the theory.     

Phonetic recalibration only occurs in speech mode

Upon hearing an ambiguous speech sound dubbed onto lipread speech, listeners adjust their phonetic categories in accordance with the lipread information (recalibration) that tells what the phoneme should be. Here we used sine wave speech (SWS) to show that this tuning effect occurs if the SWS sounds are perceived as speech, but not if the sounds are perceived as non-speech. In contrast, selective speech adaptation occurred irrespective of whether listeners were in speech or non-speech mode. These results provide new evidence for the distinction between a speech and non-speech processing mode, and they demonstrate that different mechanisms underlie recalibration and selective speech adaptation.

Three dimensions of coping and a look at their evolutionary origin

Serious problems persist concerning the conceptualization and measurement of the coping construct. This study examines the properties and factor structure of the COPE questionnaire, one of the most widely used instruments to measure coping, in a sample of 471 patients. A series of exploratory factor procedures are applied at the item- and scale-level, and the resulting solutions are tested both by their congruence with previously published structures and by confirmatory techniques. Our finding of three robust, generalizable, and parsimonious second-order dimensions—Engagement, Disengagement, and Help-Seeking—challenges the original structure. The results are discussed from an evolutionary perspective, on the assumption that the recognition of coping as the activation of vestigial defenses may make a substantial contribution to clarifying its functions and organization.     

初一学生人格特征、学习适应性与学习成绩关系的研究

以《中学生个性测验量表》和《学习适应性测验量表》为研究工具,以320名初一学生为被试,探讨初一学生个性因素、学习适应性与学习成绩的关系。结果发现,初一学生的个性特征、学习适应性与学习成绩都存在一定的相关关系;初一学生的个性因素中自控及情绪性因素和智力性因素对其学习成绩具有更好的预测作用,学习适应性因素中学习期望和家庭环境对其学习成绩具有较好的预测作用;研究同时认为,个性特征与学习适应性对初一学生学习成绩的影响可能是非常有限的。     

The Coming-Out Process and Its Adaptational and Health-Related Associations Among Gay, Lesbian, and Bisexual Youths: Stipulation and Exploration of a Model

A model is proposed and explored that links the coming-out process to the psychological functioning (i.e., self-esteem and distress) and sexual behaviors of gay, lesbian, and bisexual youths recruited from gay-focused community-based and college organizations in New York City. The coming-out process is multidimensional, consisting, as defined here, of involvement in gay/lesbian activities, attitudes toward homosexuality, comfort with homosexuality, self-disclosure of sexual identity to others, and sexual identity. The coming-out dimensions were related to self-esteem, distress, and unprotected sexual behaviors. In addition, the relations between the coming-out dimensions and unprotected sexual behaviors were explained by psychological functioning. In particular, limited involvement in gay/lesbian activities was associated with more unprotected sex. Negative attitudes toward homosexuality were related directly to more unprotected sex, and they were related indirectly to more unprotected sex by means of increasing emotional distress. These and other findings have implications for designing preventive interventions to increase the youths' psychological functioning and reduce their unprotected sexual behaviors.     

Mechanisms of long-term dark adaptation

It has previously been suggested that long-term dark adaptation is controlled by bleaching signals that regulate the activity of an allosteric, positively cooperative protein (Stabell et al., 1986a, b). Recent biochemical evidence strongly supports this assumption, indicating that the primary regulator of the light-sensitive channels in the plasma membrane of the outer segments of the photoreceptors is a homo-oligomeric, allosteric, positively cooperative protein. In this report, we discuss the possibility that signals from bleached photopigments may control the dark-adaptation process through the allosteric protein of the plasma membrane. It is suggested that the concentrations of the bleached photopigment and of the allosteric effector are reciprocal quantities.
