Cross-cultural effects on detecting multiple sources of driving hazard: Evidence from the deceleration detection flicker test

Collision rates in Malaysia are much higher than the UK; do these reflect poorer hazard perception skill or does exposure to hazardous events improve hazard detection ability? The deceleration detection flicker test (DDFT) was used to investigate the effect of experience and cross-cultural differences between Malaysian and UK drivers in their ability to detect the deceleration of a lead vehicle while simultaneously identifying any secondary hazards in side roads. Matched groups of participants with lower or higher levels of experience were recruited from the University of Nottingham in the UK and Malaysia. Malaysian drivers were significantly less accurate than UK drivers in detecting the deceleration of lead vehicles on urban roads, and significantly less accurate in detecting the presence of secondary hazards across all road types. Experienced drivers were significantly faster than novices in detecting decelerations of the lead vehicle, and were significantly more accurate in detecting the presence of secondary hazards. The study concludes that high exposure to hazardous events on the road in Malaysia does not yield expertise in this hazard perception task, although the DDFT does differentiate experience cross-culturally.     

登楼试验在低肺功能食管癌患者术前心肺功能评估中的作用研究

对需行食管癌手术的418例患者行术前静态肺功能检查后,按第一秒用力呼气量占预计值百分比（FEV1％）分为两组：肺功能正常组（NPF）和低肺功能组（LPF）。NPF组直接手术治疗,LPF组补充登楼试验,选择部分患者经术前功能锻炼后手术治疗,观察两组的临床情况。静态肺功能测定结果较差而进行登楼试验筛选后的部分患者可以通过功能锻炼提高心肺功能储备,从而能够接受手术治疗。     

Creating distinct implicit and explicit attitudes with an illusory correlation paradigm

Two studies used an illusory correlation procedure to test whether distinct implicit and explicit evaluations can result from the same learning episode. All participants learned twice as much about the qualities of one group (majority) than another (minority). In one condition, the ratio of positive to negative information was equal between groups. In other conditions, the majority group showed proportionally more positive qualities than the minority group, or vice versa. Participants in the pro-majority and pro-minority conditions formed both implicit and explicit attitudes consistent with the attitude induction. Participants in the illusory correlation condition showed the expected preference for the majority group (the illusory bias), but showed no implicit preference, suggesting distinct influences on implicit and explicit attitude formation. The effects are consistent with dual-process models in which implicit attitudes reflect accounting of covariation and explicit attitudes reflect interpretative judgments of that covariation.     

Defense Mechanism Test (DMT) and Kernberg's theory of personality organization related to adolescents in psychiatric care

75 adolescent psychiatric patients were diagnosed with the perceptual projective test the Defense Mechanism Test (DMT) and also according to Kernberg's theory of personality organization (PO). The test protocols were scored in respect of 130DMT variables and analyzed by means of partial least squares (PLS) discriminant analysis. The objective was to try to separate the three types of PO, psychotic (PPO), borderline (BPO) and neurotic (NPO) by means of the DMT and also to compare the results with a similar study on adult psychiatric patients. The results showed that it is possible to separate significantly the three groups of PO. The BPO group seemed to be heterogeneous. The results were fairly similar to those obtained with adult psychiatric patients. The overall results supported the concurrent validity of Kernberg's theory of PO and for the DMT as well. The DMT seems to be a useful diagnostic method in respect of adolescent psychiatric patients.     

一般能力倾向成套测验简介及其中国试用常模的修订

本文对一般能力倾向成套测验作了简要的介绍。为了试用,对它进行了修订。版本是以日本劳动省１９８３年修订版为蓝本的。日本的版本是来自美国。为了适合国情,对该测验在三个方面作了微小的变动。修订工作自１９８９—１９９２年初。标准化样组是由全国１７个中等以上城市初二至高三学生２１４８名构成的。男女学生的比例为１：１。该测验在结构效度上有很好的证据,稳定信度分数相当好。     

Describing the elephant: Structure and function in multivariate data

There is a unity underlying the diversity of models for the analysis of multivariate data. Essentially, they constitute a family models, most generally nonlinear, for structural/functional relations between variables drawn from a behavior domain.

Implicit health associations across the adult lifespan

Objective: Explicit reports of one’s health self-concept (e.g. rate your overall health) are commonly used in research and clinical practice. These measures predict important health outcomes, but rely on conscious introspection so may not fully capture the different components of the health self-concept (e.g. more automatic components) that relate to actual health. This study examined the health-implicit association test (health-IAT), and how it may add to our prediction of health from self-reports.

Design: 1004 participants (ages 18–85) completed this web-based study with the health-IAT (assessing self-healthy implicit associations) and explicit assessments of health.

Main outcome measures: Self-reported measures of physical functioning.

Results: The health-IAT was valid and reliable. Older age was correlated with stronger self-healthy implicit associations. Although the health-IAT did not incrementally predict self-reported markers of physical functioning when only controlling for explicit health self-concept, it was an incremental predictor once age was entered for all four models tested.

Conclusions: The health-IAT appears to be a valid and reliable new measure that assesses implicit self-concept relating to physical health. Results reveal the potential value of assessing implicit health self-concept in both research and practice, especially when taking into account age.     

Social desirability in personality inventories: Symptoms,diagnosis and prescribed cure

An analysis of social desirability in personality assessment is presented. Starting with the symptoms, Study 1 showed that mean ratings of graded personality items are moderately to strongly linearly related to social desirability (Self Deception, Impression formation, and the first Principal Component), suggesting that item popularity may be a useful heuristic tool for identifying items which elicit socially desirable responding. We diagnose the cause of socially desirable responding as an interaction between the evaluative content of the item and enhancement motivation in the rater. Study 2 introduced a possible cure; evaluative neutralization of items. To test the feasibility of the method lay psychometricians (undergraduates) reformulated existing personality test items according to written instructions. The new items were indeed lower in social desirability while essentially retaining the five factor structure and reliability of the inventory. We conclude that although neutralization is no miracle cure, it is simple and has beneficial effects.     

Effects of an 8-week meditation program on the implicit and explicit attitudes toward religious/spiritual self-representations

Explicit self-representations often conflict with implicit and intuitive self-representations, with such discrepancies being seen as a source of psychological tension. Most of previous research on the psychological effects of mindfulness-meditation has assessed people’s self-attitudes at an explicit level, leaving unknown whether mindfulness-meditation promotes changes on implicit self-representations. Here, we assessed the changes in implicit and explicit self-related religious/spiritual (RS) representations in healthy participants following an 8-week mindfulness-oriented meditation (MOM) program. Before and after meditation, participants were administered implicit (implicit association test) and explicit (self-reported questionnaires) RS measures. Relative to control condition, MOM led to increases of implicit RS in individuals whit low pre-existing implicit RS and to more widespread increases in explicit RS. On the assumption that MOM practice may enhance the clarity of one’s transcendental thoughts and feelings, we argued that MOM allows people to transform their intuitive feelings of implicit RS as well as their explicit RS attitudes.
