Objective: Planning can bridge the gap between intentions and action, but what bridges the gap between planning and action? This study helps to answer the question by disentangling the interrelationships between self-efficacy, planning and preparatory behaviours in predicting physical activity. Preparatory behaviours are tested as a working mechanism of planning. Moreover, it is tested whether the utility of preparatory behaviours depends on an individual’s level of self-efficacy.Methods: A survey assessed planning, self-efficacy and preparatory behaviours for physical activity. Adults (N = 166) provided data at two measurement points. In a longitudinal model, preparatory behaviours were specified as a mediator between planning and physical activity. Self-efficacy was specified as a possible moderator at two points in the model.Results: Preparatory behaviours mediated the relationship between planning and physical activity. An interaction between self-efficacy and preparatory behaviours on physical activity was found, indicating that individuals with low self-efficacy beliefs were more active if they engaged more frequently in preparatory behaviours.Conclusion: Planning seems to stimulate preparatory behaviours, which in turn make future physical activity more likely. Furthermore, as performing preparatory behaviours represent a step forward towards the enactment of behavioural goals, preparatory behaviours may be particular beneficial for individuals afflicted by self-doubts regarding physical activity. 相似文献

Bicycle/pedestrian shared paths are an increasingly popular solution to providing cycling infrastructure, despite evidence suggesting safety issues. Improved design and management of shared paths should be informed by understanding of bicyclist and pedestrian behaviour on shared paths, and of relevant safety initiatives (e.g. centreline marking). However, relevant research is lacking. Bicyclist/pedestrian passing events (n = 407) were observed on three relatively busy shared paths in Sydney, Australia – one of them without centreline marking. User characteristics, relevant behaviours and incidents (aggression, near-misses, crashes) were recorded. A tendency toward left-hand travel, as on Australian roads, was stronger for cyclists than for pedestrians, and where centreline was present. Cyclists were often estimated to travel above 10 km/h, a speed limit that has been suggested based on pedestrian safety considerations, but that would be unacceptable for long stretches of commuter cycling. Centreline was associated with lower estimated speeds. Cyclists typically adhered to their responsibility of giving way to pedestrians, but often passed on the left, passed too close, passed without slowing, or passed without warning (e.g. with a bell). Use of mobile telephones and mp3 players is common, particularly amongst pedestrians. Five near collisions were observed, and 53 survey participants reported 2 collisions and 13 near misses. Contributing factors appear to include path users using potentially distracting devices, or straying from the rules of thumb to keep to the left, and to overtake on the right.A survey of cyclists and pedestrians suggested that there are issues with perceptions of space ownership. These results represent an important contribution to the evidence-base for initiatives to improve the safety of shared paths. 相似文献

Although the potential usefulness of the offence action–offender characteristic (A–C) relationships is widely accepted and operational ‘offender profiling’ units now exist around the world, few such relationships have been empirically established. To explore this, the offending action patterns within 111 sexual assault cases from South Korea were coded in terms of 16 distinctive, objective crime scene criteria and subjected to an agglomerative hierarchical cluster analysis. Background psychiatric and general characteristics, Personality Assessment Inventory (PAI) scale scores, and criminal histories were described for each cluster. The cluster analysis drew attention to six clusters or behavioural profiles within the sexual assaults. Cluster 1 included serial offenders who aggressively raped and robbed adult women, with some pseudo‐intimate sexual behaviour, in their homes. Two thirds of these offenders had histories of sexual assault. Cluster 2 included offenders who again targeted adults in their homes, but without pseudo‐intimate sexual behaviour. Cluster 3 included offenders who targeted adults outdoors at night. These offenders showed high antisocial personality PAI scores and psychiatric histories of sexual sadism. Cluster 4 included unarmed offenders who targeted adults in their homes without robbery. These offenders often had psychiatric histories of depression. Cluster 5 included offenders who targeted adults outdoors with a blitz‐style attack, and Cluster 6 included offenders who targeted minors outdoors, without weapons, using a confidence‐trick style of approach. Paedophilia and histories of psychiatric treatment were prominent amongst these offenders. The results indicate therefore some of the key empirical relationships that future research may develop as the basis for sexual assault ‘profiles’. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献

The present research intends to shed light on the processes enabling political minorities to transition into normatively acceptable groups, by investigating how a previously marginalised far‐right movement (the French National Front) is progressively becoming mainstream. Drawing on the social representations approach, we argue that perceived social norms play a pivotal role in this process. Using a longitudinal and experimental design, the study (N = 233) was implemented in the ecological context of the 2012 French presidential election at a Parisian university campus, a traditional anti‐far‐right bastion. We tested whether the electoral campaign altered the perceptions of social norms, whether the perceived social norms were easily malleable in this specific context and, most important, whether they influenced people's willingness to speak out in public against the far‐right movement. The findings support affirmative answers to all three questions. We conclude that, in periods of collective uncertainty, changing perceptions of social norms might play an important role in the weakening of public opposition to far‐right movements. This, in turn, helps to explain the recent transition to mainstream recognition of a number of previously marginalised political movements in Europe and around the globe. 相似文献

视频游戏对青少年行为影响的研究焦点主要集中在暴力视频游戏带来的消极影响上。随着研究的深入以及积极心理学的兴起,研究者开始关注亲社会视频游戏对青少年行为的积极影响,并进行了相关的研究,研究大多以一般学习模型为理论框架。一般学习模型认为亲社会视频游戏通过影响与亲社会相关的认知、情感和生理唤醒而对亲社会行为产生作用。已有研究显示,亲社会视频游戏会促进青少年的亲社会行为,同时减少青少年的攻击性行为。研究者们采用多种方法探索亲社会视频游戏影响青少年行为的心理机制,证明了一般学习模型的理论构想。未来研究需要进一步研究性别、人格、文化等因素的影响,并开展相关的认知神经机制研究。 相似文献

The remarkable cognitive abilities of bats indicate that they may recognise particular conspecifics. Because of their highly developed auditory system, it is obvious that vocalisations of bats may give information about the individual emitting them. In a field study of the social behaviour in the Indian false vampire bat (Megaderma lyra), two different types of vocalisation were recorded and analysed. The bats emitted these vocalisations only while aggregating with conspecifics inside the day roost. The “landing strophe” consisted of a number of brief multiharmonic downward frequency-modulated (FMdown) sounds which levelled off as a constant frequency (CF), and the “clatter strophe” was composed of a number of multiharmonic FMdown sounds which became shallow at the end as a short CF. The sounds of the landing strophe and the ¶clatter strophe differed in repetition rate, duration, harmonic components and frequency. Time pattern and peak frequency of the two sound types differed highly significantly between single, unidentified bats. The sounds were inter-individually distinct when the three parameters were combined as an acoustical space. Therefore, these vocalisations might be used for individual recognition in adult bats. 相似文献

Objective: The aim of the present study was to explore whether constructs within the Prototype Willingness Model (PWM) predicted risky drinking as measured by AUDIT-C, drinking harms and unplanned drunkenness in a sample of UK young adults. Previous studies exploring the PWM often do not use validated measures of alcohol consumption, and the outcomes of risky drinking are underexplored. Design: An online prospective study design with 4 week follow-up was employed and 385 young adults completed the study (M age?=?21.76, SD?=?3.39, 69.6% female; 85.2% students). Main outcome measures: Intentions to get drunk, AUDIT-C, drinking harms experienced in the last 4 weeks, and unplanned drunkenness in the last 4 weeks. Results: Heavy and non-drinker prototype similarity predicted AUDIT-C, drinking harms and unplanned drunkenness when controlling for past behaviour and reasoned action pathway constructs. Intentions and willingness both mediated the relationship between prototype perceptions and AUDIT-C. Conclusion: This study supports the use of the PWM in the prediction of AUDIT-C, drinking harms and unplanned drinking in a UK sample. Prototype perceptions influenced behaviour via both reasoned and reactive cognitions. Targeting similarity to heavy and non-drinker prototypes should be the focus of future interventions in this population. 相似文献

The thousands of deaths and disabilities due to workplace accidents and injuries each year emphasize the importance of safety research. Despite occupational safety research that has contributed to identifying antecedents of safety, little is known about why and how safety knowledge leads to safety behaviours and how personal and situational factors interact to promote occupational safety. Using a multilevel, multisource, and time-lagged research design, the present study investigates whether safety knowledge affects safety behaviours through safety attitudes and further tests whether supervisory safety attitudes can impact the strength of these relationships and play a role as moderators of the proposed mediated relationship. Data were collected from workers (N = 177) and supervisors (N = 42) in a construction company in the energy industry at two time points. Results indicate full support for the moderated mediation model, demonstrating that worker safety attitudes partially mediate the relationship between safety knowledge and safety behaviours. Moreover, when supervisors had positive attitudes towards safety, both the direct relationship between worker safety attitudes and safety behaviours and the indirect relationship between safety knowledge and safety behaviours were more positive compared to when supervisors had negative safety attitudes. Theoretical and practical implications for occupational safety are discussed. 相似文献
