Autonomous forms of motivation underpinning injury prevention and rehabilitation among police officers: An application of the trans-contextual model

The present study applied the trans-contextual model (TCM) to understand the motivational processes underpinning workers?? injury prevention and rehabilitation intentions and behavior. Full-time police officers (N?=?207; M age?=?37.24, SD?=?9.93) completed questionnaire measures of the TCM variables. Covariance-based SEM for the full sample revealed that the effect of autonomy support from supervisor on autonomous motivation for injury prevention (M-injury) was fully mediated by autonomous work motivation (M-work), and the effect of M-injury on intention was fully mediated by attitude and subjective norm. Variance-based SEM for the 87 participants who had recent occupational injury showed that the effect of autonomy support from supervisor on autonomous treatment motivation (M-treatment) was partially mediated by M-work, and the effect of perceived autonomy support from physician on treatment adherence was fully mediated by M-treatment. There was no effect of treatment adherence on recovery length. Findings support the motivational sequence of the TCM in an occupational context.     

Juvenile homosexual homicide

Limited information exists on juvenile homosexual homicide (JHH), that is, youths who perpetrate sexual homicides against same-sex victims. Only a handful of cases from the United States and internationally have been described in the literature. This study, the first of its kind, examines the epidemiology, victimology, victim-offender relationship, and weapon-use patterns in JHH offenders using a large U.S. database on homicide spanning three decades. The data for this study were derived from the Federal Bureau of Investigation's Supplementary Homicide Reports (SHRs) for the years 1976 through 2005. A total of 93 cases of JHH were identified. On average, three of these crimes occurred annually in the U.S., and there was a marked decline in its incidence over the study period. Ninety-five percent were male offender-male victim cases and 5% were female offender-female victim cases. JHH offenders were over-represented amongst all juvenile sexual murderers, similar to their adult counterparts. The majority of these boys were aged 16 or 17 and killed adult victims. They were significantly more likely to kill adult victims than other age groups, to be friends or acquaintances of the victims, and to use contact/edged weapons or firearms. Most offenders killed same-race victims, although Black offenders were significantly more likely than White offenders to kill interracially. A case report is provided to illustrate JHH. Further research is needed to promote our understanding of the pathogenesis, etiology, and associated risk factors for this aberrant form of murder by children.     

The impact of an 8-day intensive treatment for adolescent panic disorder and agoraphobia on comorbid diagnoses

Previous research findings have shown positive effects of cognitive-behavioral therapy for primary anxiety disorders as well as for nonprimary, co-occurring anxiety disorders. In this study, we analyzed data from an existing randomized controlled trial of intensive treatment for panic disorder with or without agoraphobia (PDA) to examine the effects of the treatment on comorbid psychiatric diagnoses. The overall frequency and severity of aggregated comorbid diagnoses decreased in a group of adolescents who received an 8-day treatment for PDA. Results suggest that an 8-day treatment for PDA can alleviate the symptoms of some specific comorbid clinical diagnoses; in particular specific phobias, generalized anxiety disorder, and social phobia. These findings suggest that an intensive treatment for PDA is associated with reductions in comorbid symptoms even though disorders other than PDA are not specific treatment targets.     

Enacting modesty in Chinese culture: The joint contribution of personal characteristics and contextual features

This research revealed the joint impact of personality traits, social axioms, role relationships and the privacy of social situations on the enactment of three types of modesty, namely, avoiding attention, self‐effacement, and enhancement of others, among Hong Kong Chinese teenage females. The modest personality trait was found to relate positively to these modest behaviours. An individual's belief in reward for application significantly predicted self‐effacement, and the belief in social cynicism significantly predicted avoiding attention and enhancement of others. Contextual variables as measured by the role relationships and the privacy of the social setting also significantly affected the levels of these modest behaviours.     

Does substance abuse contribute to further risk of falls in dementia

This study aimed to predict the risk of falls by focusing on substance abuse in the elderly with dementia. Our national cross-sectional survey included 1210 elderly Malaysian demented subjects. The study identified the effects of age, ethnicity, sex differences, marital status, educational level, and substance abuse on the likelihood of falls in the elderly with dementia. The multivariate logistic regression model was used to analyze data collected from samples. The prevalence of falls was about 17% among subjects and significantly increased with age (p = .006). Furthermore, the results showed that age (OR = 1.03), ethnicity (OR = 1.69), substance abuse (OR = 1.68), and female sex (OR = 1.45) significantly enhanced the risk of falls in respondents (p < .05). Educational level and marital status had no significant effects on the likelihood of falls (p > .05). However, the findings provided evidence of an additional effect of substance abuse on further risk of falls in older adults with dementia.     

Generality of a congruity effect in judgements of relative order

The judgement of relative order (JOR) procedure is used to investigate serial-order memory. Measuring response times, the wording of the instructions (whether the earlier or the later item was designated as the target) reversed the direction of search in subspan lists (Chan, Ross, Earle, & Caplan Psychonomic Bulletin & Review, 16(5), 945–951, 2009). If a similar congruity effect applied to above-span lists and, furthermore, with error rate as the measure, this could suggest how to model order memory across scales. Participants performed JORs on lists of nouns (Experiment 1: list lengths = 4, 6, 8, 10) or consonants (Experiment 2: list lengths = 4, 8). In addition to the usual distance, primacy, and recency effects, instructions interacted with serial position of the later probe in both experiments, not only in response time, but also in error rate, suggesting that availability, not just accessibility, is affected by instructions. The congruity effect challenges current memory models. We fitted Hacker’s (Journal of Experimental Psychology: Human Learning and Memory, 6(6), 651–675, 1980) self-terminating search model to our data and found that a switch in search direction could explain the congruity effect for short lists, but not longer lists. This suggests that JORs may need to be understood via direct-access models, adapted to produce a congruity effect, or a mix of mechanisms.     

Positive and negative emotions modulate attention allocation in color-flanker task processing: Evidence from event related potentials

The purpose of this study was to explore the effects of emotions in conflict processing. Behavioral and event related potential (ERP) data were acquired from twenty participants while they were performing a color-flanker task, in which the stimuli were emotional and neutral words. Through temporal principal component analysis (PCA) of ERP, three PCA components were extracted with their time windows mapped to three ERP components: N1, N2 and P3. Further analysis revealed, when the stimuli were the positive words, N1 was marginally greater for the congruent condition than for the incongruent condition (p = .06); while the stimuli were the negative words, N1 was greater for the incongruent condition than for the congruent condition (p = .02); however, no significant interaction effect involving the valence of words (positive vs. negative) and the color congruency (congruent vs. incongruent) was found on N2, P3 and the behavior data. The result suggested that negative emotion might lead to more attention allocation in the incongruent processing, while positive emotion might lead to more attention allocation in the congruent processing. Furthermore, ERP source analysis in the present study confirmed anterior cingulate cortex was involved in the conflict monitoring mechanism.     

Differential Roles of Physical Attractiveness and Earning Capability in Explaining Sense of Power among Dating Individuals in China: A Gender Comparison

This cross-sectional study examined how self-assessed physical attractiveness and earning capability were associated with individuals’ sense of power through self-perceived mating success and investment size in romantic relationships among 196 young adults (88 men, 98 women) from Nanjing, China. Using path analysis, we tested the following hypotheses: self-assessed physical attractiveness would be more strongly associated with self-perceived mating success among women than men, whereas self-assessed earning capability would be more strongly linked to self-perceived mating success among men than women (H1); relative physical attractiveness, as compared to their partners’, would be more strongly associated with men’s rather than women’s self-perceived investment size, whereas relative earning capability would be more strongly related to women’s rather than men’s investment size (H2); for both men and women, self-perceived mating success would be positively associated with sense of power, whereas self-perceived investment size would be negatively associated with sense of power (H3). Results indicated that self-perceived physical attractiveness and earning capability were associated with self-perceived mating success similarly for both men and women, failing to support H1. Whereas relative physical attractiveness was negatively associated with investment in the relationship similarly for two genders, the negative association between relative earning capacity and investment size was only significant for women. H2 was partially supported. Finally, self-perceived mating success and investment size were significantly associated with sense of power in the expected directions for both genders, lending support to our H3. Results are discussed in light of gender differences in mate preferences and the investment theory.     

Chinese teachers’ use of humour in coping with stress

The purpose of this study was to examine the mentality of Chinese teachers regarding their use of humour in coping with stress. Specifically, the study investigated their frequency of use of humour in coping with stress as compared to other coping styles and their perceptions about the relationship of humour with other coping styles. Data were collected from a sample of 789 Chinese teachers holding teaching posts at local Hong Kong secondary schools. Based on responses made to the COPE questionnaire, there was evidence that Chinese teachers had a lower frequency of use of humour as compared to other coping styles. As suggested by the results of a factor analysis, there was a perception among Chinese teachers that the use of humour was related more closely to escaping and/or avoidance as coping strategies, but more differentiable from problem‐focused/task‐oriented and emotional/social coping. It is interesting to find that the results of our study echoed those of a previous crosscultural comparison between Chinese and Canadian university students, in which the Chinese university students reported less use of humour in coping with stress than did their Canadian counterparts. These results have provided some empirical support for the notion that “humor has been traditionally given little respect in Chinese culture mainly due to the Confucian emphasis on keeping proper manners in social interactions” (Yue, 2010, p. 403). As teachers in Chinese societies are regarded as persons who are full of wisdom and capable of problem‐solving, it is expected that they should act as role models to their students. These social expectations on Chinese teachers could further mould their perceptions on the use of humour in coping with stress.     

Regulatory focus influences perseveration and distractibility in task switching

In two experiments, we investigated the effect of regulatory focus (Higgins, Am Psychol, 52, 1280–1300, 1997) on people’s maintenance and switching behavior. In the experimental tasks, participants were asked to react selectively to one category of stimuli while ignoring the other. After several practice trials, participants had to switch either to new stimuli which were paired with former target stimuli (i.e., in the perseveration condition), or switch to former distracter stimuli which were paired with new stimuli (i.e., in the learned irrelevance condition). Results from both experiments indicated that a promotion focus promoted switching to new stimuli in the perseveration condition, at the cost of poorer performance on switching to former distracters in the learned irrelevance condition. This pattern of results applied to both chronic individual differences in regulatory focus (Experiment 1), and regulatory focus temporarily manipulated in the laboratory (Experiment 2). It suggests that whereas a promotion focus indeed promotes cognitive flexibility, it also incurs a cost in terms of increased likelihood of being distracted.
