Bars and lines: A study of graphic communication

Interpretations of graphs seem to be rooted in principles of cognitive naturalness and information processing rather than arbitrary correspondences. These predict that people should more readily associate bars with discrete comparisons between data points because bars are discrete entities and facilitate point estimates. They should more readily associate lines with trends because lines connect discrete entities and directly represent slope. The predictions were supported in three experiments--two examining comprehension and one production. The correspondence does not seem to depend on explicit knowledge of rules. Instead, it may reflect the influence of the communicative situation as well as the perceptual properties of graphs.     

An informal online learning community for student mental health at university: a preliminary investigation

As a potential solution to increasing demands on mental health services at universities, this project seeks to develop an informal online learning community for mental health support and education. Students' use of the Internet and Information and Communication Technologies (ICT), especially to access health information, provides a supporting rationale for this project. The design for this study is grounded in the pedagogical principles of informal learning and the practices for building successful online communities. The student online mental health community has been implemented at the authors' university (University of Dublin, Trinity College) for one academic term and the initial analysis of its usage is positive. Features that are being positively evaluated are the role of the reader participant, disinhibition that arises from anonymity, online provision acting as a gateway to further support, and online provision reaching an audience who ordinarily do not use face-to-face services. At the same time, difficulties specific to this type of community have surfaced, including technical issues, implications of anonymity and user safety.     

Childhood anxiety and attention to emotion faces in a modified stroop task

This study used an emotional face stroop task to investigate the effects of self‐report trait anxiety, social concern (SC), and chronological age (CA) on reaction time to match coloured outlines of angry, happy, and neutral faces (and control faces with scrambled features) with coloured buttons in a community sample of 74 children aged 6 –12 years. The results showed an interference of colour matching for angry (relative to neutral) faces in children with elevated SC. The same effect was not found for happy or control faces. In addition, the results suggest that selective attention to angry faces in children with social concern (SC) was not significantly moderated by age.     

Mizuko kuyō in the abortion cultural wars: The rhetorical appropriation of Japanese Buddhism by non-Buddhist Americans

Mizuko kuyō, the popular Japanese Buddhist memorial service for aborted fetuses, has been increasingly appropriated by both sides of the contentious American abortion debate. In the wake of exposure to the idea of mizuko kuyō, both pro-life and pro-choice Buddhist appropriators resort to discussions of the ritual because they feel it helps them strengthen the weaknesses of their own sides and undermine the positions of their opponents. Pro-life Americans use mizuko kuyō to prove that they care about women, not just fetuses, and that their convictions do not arise simply out of private religious feelings but objective psychological and medical facts. Pro-choice Americans, on the other hand, use mizuko kuyō to demonstrate that they care about families and children, not just women, and that they are sensitive not only to the secular but also the religious aspects of life and abortion. In the process, pro-life Christians, who seem to be primarily motivated by their exclusivist and authoritarian Biblical convictions, turn for support to a non-theistic religion they otherwise oppose; pro-choice feminists, who seem to have chiefly secular reasons for supporting abortion rights, turn for support to a supernatural entity and his retinue of angry fetal ghosts.     

Reconsidering the “aspiration–expectation gap” and assumed gender differences among urban youth

The present study investigated the relevance of the “aspiration–expectation gap” and traditional gender differences among urban youth in middle school and high school (N = 294). Results failed to indicate a significant difference between the occupational prestige levels of aspired and expected careers, but did indicate a significant difference between aspired and expected levels of education. In general, the proportion of girls significantly outweighed the proportion of boys in traditionally “masculine” occupations with high levels of prestige; girls also had higher levels of occupational prestige than boys in terms of careers they hoped and expected to obtain. Black and bi/multi-racial youth expected to have higher levels of education than White youth.     

Driver responses to motorcycle and lead vehicle braking events: The effects of motorcycling experience and novice versus experienced drivers

In many countries, motorcyclists are over-represented in traffic collision fatalities and injuries compared to vehicle registrations. Why drivers may violate the right-of-way of motorcyclists traveling as lead vehicles in front of drivers is empirically examined in two studies that were conducted with a moderate-fidelity driving simulator. The purpose of the first study was to determine if drivers, who also held a motorcycle license (N = 16), drove cars differently than regular drivers (N = 16) around motorcycles. The two groups did not differ on responses to motorcycling braking events, which was consistent with previous research on car following. The second study compared the driving performance of sixteen novice teenage drivers (M = 16.2 years of age) to 15 experienced drivers (M = 32.9) over the span of six monthly simulator sessions. Novice drivers’ perception response times (PRT) to the braking events were significantly longer than those of the experienced drivers. PRTs to motorcycle and lead vehicle braking events decreased over sessions. For all participants, PRTs to the motorcycle events were longer than to the car events. The implications of these results for motorcyclists and drivers with different levels of experience are discussed.     

Do positive children become positive adults? Evidence from a longitudinal birth cohort study

BACKGROUND: Little is known about the long-term consequences of positive wellbeing in childhood in the general population. We used the MRC National Survey of Health and Development (the British 1946 birth cohort) to test associations between adolescent positive wellbeing and social functioning in midlife. METHOD: Temperament and behaviour at ages 13 and 15 years were rated by school teachers on a range of criteria. These mostly referred to absence or presence of conduct and emotional problems, but four items allowed positive ratings: 'very popular with other children', 'unusually happy and contented', 'makes friends extremely easily' and 'extremely energetic, never tired'. In addition, at age 16 years survey members self-completed the Maudsley Personality Inventory, from which a summary measure of extraversion was derived, as this was previously found to be associated with midlife positive wellbeing in this cohort. RESULTS: Being a happy child, defined as receiving at least two of the above teacher ratings, was positively associated with midlife functioning and wellbeing, specifically a low probability of lifetime emotional problems, a high frequency of contact with friends or relatives, engagement in social activities, and to a lesser extent feeling satisfied with accomplishments in working life. These associations were independent of father's social class, childhood cognition, educational attainment, and midlife occupational social class. There were no independent associations between being a happy child and educational or occupational attainment, being married, engagement in prosocial activities, taking leadership in community activities, and with life satisfaction in general or with family life. Extraversion was associated with a low probability of lifetime emotional problems, high engagement in social activities, being married, general midlife life satisfaction, and satisfaction with family life, but not with social contact, prosocial activity, leadership activity, or work satisfaction. While childhood conduct and emotional problems were associated with few of the social and life satisfaction outcomes, the former were negatively associated with educational and occupational attainment, and positively with divorce, whereas the latter were negatively associated with being married. CONCLUSIONS: Prospectively rated childhood wellbeing has long-term beneficial links to adult functioning; our results also support the view that positive wellbeing has a unique impact on these outcomes, and does not merely represent the absence of mental ill-health.     

Talking and driving: applications of crossmodal action reveal a special role for spatial language

Talking reduces attention resulting in real-world crash risks to drivers that talk on a phone and drive. Driving is a behavior that is very demanding on spatial attention, suggesting potentially large interference by spatial codes in language. The current study investigated how different types of verbal codes influence visual attention during dual-task performance. In two experiments, participants performed a spatial or non-spatial verbal task while simultaneously performing a visual attention task. The results showed a larger decrement to visual attention performance when participants were concurrently engaged in a spatial verbal task. The results of the second experiment isolated this effect to the right cerebral hemisphere, consistent with a role for shared right parietal resources. These results are consistent with the idea that processing codes are an important component of coordinating talking and driving but generally inconsistent with a broad class of bottleneck approaches that describes dual-task decrements but treats component tasks as cognitively equivalent.
