Time perception and time perspective differences between adolescents and adults

The present experiment aimed to investigate the differences in time perception and time perspective between subjects representing two developmental stages, namely adolescence and middle adulthood. Twenty Chinese adolescents aged 15–25 and twenty Chinese adults aged 35–55 participated in the study. A time discrimination task and a time reproduction task were implemented to measure the accuracy of their time perception. The Zimbardo Time Perspective Inventory (Short-Form) was adopted to assess their time orientation. It was found that adolescents performed better than adults in both the time discrimination task and the time reproduction task. Adolescents were able to differentiate different time intervals with greater accuracy and reproduce the target duration more precisely. For the time reproduction task, it was also found that adults tended to overestimate the duration of the target stimuli while adolescents were more likely to underestimate it. As regards time perspective, adults were more future-oriented than adolescents, whereas adolescents were more present-oriented than adults. No significant relationship was found between time perspective and time perception.     

Three-Mode Factor Analysis by Means of Candecomp/Parafac

A three-mode covariance matrix contains covariances of N observations (e.g., subject scores) on J variables for K different occasions or conditions. We model such an JK×JK covariance matrix as the sum of a (common) covariance matrix having Candecomp/Parafac form, and a diagonal matrix of unique variances. The Candecomp/Parafac form is a generalization of the two-mode case under the assumption of parallel factors. We estimate the unique variances by Minimum Rank Factor Analysis. The factors can be chosen oblique or orthogonal. Our approach yields a model that is easy to estimate and easy to interpret. Moreover, the unique variances, the factor covariance matrix, and the communalities are guaranteed to be proper, a percentage of explained common variance can be obtained for each variable-condition combination, and the estimated model is rotationally unique under mild conditions. We apply our model to several datasets in the literature, and demonstrate our estimation procedure in a simulation study.     

School-Based Cognitive Mindfulness Intervention for Internalizing Problems: Pilot Study with Hong Kong Elementary Students

Childhood internalizing problems such as anxiety and depression can have serious personal, familial and societal repercussions, including drug and alcohol abuse, delinquency, unplanned pregnancy, and even suicide. There is little research on mindfulness interventions for children with clinical levels of internalizing problems, and school-based mindfulness research with children has focused on non-clinical groups. We employed a two-stage screening and intervention procedure to evaluate an in-school mindfulness-based cognitive intervention for Hong Kong children with subclinical internalizing difficulties. Ninety-three fourth to sixth graders were screened, and twenty students (age 9–13, median age 10) highest among their peers on internalizing problems, but lowest on externalizing problems, participated in a 9-week group mindfulness-based intervention. We employed a two-phase open trial design, with random assignment to an immediate intervention group or wait-list control group. In single-trial analysis, one-tailed dependent sample t-tests showed significant decreases in both worry and in symptoms of panic disorder, obsessive compulsive disorder, generalized anxiety and overall internalizing problems. In a randomized controlled trial analysis, the immediate intervention group evidenced larger but nonsignificant reductions on almost all measures. Eighty-five percent of the participants rated the program as helpful, and 65–80 % reported improvement in handling emotions and interpersonal relationships at post-treatment, with some treatment gains maintained at 3-month follow-up. These preliminary findings have encouraging implications for implementing time-limited school-based mindfulness interventions targeting elevated childhood internalizing difficulties.     

Mental health of Chinese primary care patients with lower urinary tract symptoms

The aim of this study was to evaluate the mental health of Chinese primary care patients with lower urinary tract symptoms (LUTS). This was a cross-sectional observational study. Five hundred and nineteen subjects with LUTS completed a structured questionnaire containing the Depression, Anxiety, and Stress Scale-Short Form, the International Prostate Symptom Score, the adapted International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form and questions about socio-demographics. Overall, 17.7% of subjects reported depressive symptoms, 24.3% anxiety symptoms and 9.6% stress symptoms. In males, demographic factors associated with poorer mental health included being not married; clinical factors included higher LUTS severity, weak stream, straining and mixed urinary incontinence. In females, demographic factors associated with poorer mental health included being younger, not married and lower household income; clinical factors included higher LUTS severity, incomplete bladder emptying, urgency and weak stream. Chinese primary care patients with LUTS appear to be an at-risk group for poorer mental health with increased prevalence of anxiety and depressive symptoms and may require routine screening to identify those who may require more tailored interventions to address both their urinary symptoms and psychological distress.     

Sibling relationships and civic engagement: A longitudinal study of Chinese young adults

This study examined the longitudinal associations of sibling intimacy and conflict with civic attitudes and behaviours among Chinese young adults. At two time points separated by about 12 months, questionnaire data were collected from 272 Chinese college students (mean age at Time 1 = 19.68 years; 69% female), students who studied in Hong Kong and had at least one sibling. Students rated their intimacy and conflict with their siblings and their parents at Time 1, and their civic attitudes and behaviours at both time points. Hierarchical regression revealed that, controlling for demographic characteristics and parent–child intimacy and conflict, sibling intimacy predicted increases in both civic attitudes and behaviours. Sibling conflict was a non-significant predictor, however. Findings highlighted the roles of siblings in understanding civic development in young adulthood and the utility of targeting sibling intimacy as means to foster young adults' positive attitudes to and active participation in civic activities.     

Relationship between the Delay Task and Rating Scale measures of Inattention and Hyperactivity

A group of 187 elementary school children were administered a microcomputer version of the Delay Task (Gordon, 1979) in which responses were reinforced only when they followed the preceding response by at least 6 seconds. They were also rated on the Conners Teacher Rating Scale (CTRS) by their classroom teacher. Performance on the Delay Task was not correlated with any of the CTRS subscales for the overall sample. Sex differences were found in the Conduct, Inattention, and Hyperactivity factors of the CTRS. No sex difference was found for performance on the Delay Task. When performance on the Delay Task was correlated with the four CTRS factors by sex, correlations between the Delay Task and the inattention subscale and hyperactive subscale were significant only for the male subsample. Implications of the findings for assessment of hyperactivity are discussed.The research was supported by an equipment grant from the University of Auckland Research Committee.

Journalism as Model for Civic and Information Literacies

Journalism can serve as a generative disciplinary context for developing civic and information literacies needed to meaningfully participate in an increasingly networked and mediated public sphere. Using interviews with journalists, we developed a cognitive task analysis model, identifying an iterative sequence of production and domain-specific cognitive constructs of journalism expertise. We diagnose common discrepancies between professional practices and typical youth journalism pedagogies, and offer suggestions for teaching participatory politics and civic literacies through journalism.     

Perspectives on prediction: Does third-person imagery improve task completion estimates?

People typically underestimate the time necessary to complete their tasks. According to the planning fallacy model of optimistic time predictions, this underestimation occurs because people focus on developing a specific plan for the current task and neglect the implications of past failures to meet similar deadlines. We extend the classic planning fallacy model by proposing that a phenomenal quality of mental imagery – the visual perspective that is adopted – may moderate the optimistic prediction bias. Consistent with this proposal, participants in four studies predicted longer completion times, and thus were less prone to bias, when they imagined an upcoming task from the third-person rather than first-person perspective. Third-person imagery reduced people’s focus on optimistic plans, increased their focus on potential obstacles, and decreased the impact of task-relevant motives on prediction. The findings suggest that third-person imagery helps individuals generate more realistic predictions by reducing cognitive and motivational processes that typically contribute to bias.     

THE EFFECTS OF FUNCTIONAL ANALYSIS TEST SESSIONS ON SUBSEQUENT RATES OF PROBLEM BEHAVIOR IN THE NATURAL ENVIRONMENT

The present study was conducted to determine whether elevated response rates that occurred in an experimental functional analysis were correlated with higher post‐session response rates in the natural environment. Functional analyses indicated that the problem behavior of four children with developmental disabilities was maintained by common sources of reinforcement. Observational assessment in the natural environment showed no differences in post‐session rates compared with pre‐session rates for three participants, and the data for the fourth participant were equivocal. Overall, no convincing evidence was found to suggest that functional analyses might worsen post‐session problem behavior in the natural environment. Copyright © 2012 John Wiley & Sons, Ltd.     

Predictors and Outcomes of Experiences Deemed Religious: A Longitudinal Investigation

The two studies reported here revised Hunt's (1972) LAM (Literal, Anti-Literal, Mythological) Scale to include a Metaphorical dimension. The first study investigated the relationship between preference for literal versus metaphorical interpretations of religious language and structural levels of religious thinking. As predicted, participants who preferred a literal interpretation of religious statements gave evidence of a low developed structure of religious judgment. The predicted relationship between preference for metaphorical interpretations and style of religious thinking was not found. The second study compared samples of participants scoring highest on the Literal and the Metaphorical subscales. Literal participants scored lower on imaginative thinking and made greater use of religious language in an objectifying manner than did metaphorical participants. The meaning of these data for mature religious thinking is considered.
