This paper reviews studies explicitly applying the Theory of Planned Behaviour (TPB) to behaviour change interventions. A systematic and multiple search strategy identified 30 papers, describing 24 distinct interventions. Studies were rarely explicit about use of the TPB. The TPB was mainly used to measure process and outcome variables and to predict intention and behaviour, and less commonly to develop the intervention. Behaviour change methods were mostly persuasion and information, with increasing skills, goal setting, and rehearsal of skills used less often. When reported, half of the interventions were effective in changing intention, and two-thirds in changing behaviour, with generally small effect sizes, where calculable. Effectiveness was unrelated to use of the theory to develop interventions. Evidence about mediation of effects by TPB components was sparse. The TPB may have potential for developing behaviour change interventions, but more comprehensive studies are needed that compare the utility of the TPB with other social cognition models and behavioural techniques. 相似文献

In Stages of Change studies on dietary fat, standard algorithms allocate many respondents to the maintenance stage and their stage allocations are not always supported by objective criteria. In defining the preparation stage standard instruments emphasise inactivity allied to confident intention to change. In contrast Lamb and Joshi's (1996) staging instrument emphasises inconsistent effort, and thereby allocates inconsistently active respondents to preparation when a standard instrument might place them in action or maintenance. In the current cross-sectional study 375 respondents completed a standard algorithm, the Lamb and Joshi instrument and a 24-hour recall food diary. They also gave judgements of their current weight and diet. Unlike the standard instrument, the Lamb and Joshi instrument: (a) allocated fewer respondents to action/maintenance, (b) discriminated key behavioural stages by percent fat in diet, and (c) captured non-linear discontinuities in the respondents’ weight and diet self-perceptions. Such discontinuities in the psychosocial processes are predicted by the transtheoretical model, and support the claim that its stages are categorically distinct rather than artificially isolated points on a continuum. Distinguishing between respondents who describe themselves as consistently active and those who describe themselves as inconsistently active may help to overcome some apparent problems in the application of the transtheoretical model to behavioural change. 相似文献

This project explores the impact of Barack Obama’s presidential campaign and the resulting high levels of exposure to a positive, counter-stereotypic Black exemplar, on prejudice and stereotyping among non-Black participants. We found dramatically decreased levels of implicit anti-Black prejudice and stereotyping as compared with bias observed previously at the same institutions and in the literature. Providing some insight why the bias was reduced, Study 1 demonstrated that participants had positive Black exemplars come to mind or anticipated that other people have positive exemplars come to mind when they thought of Black people and this was associated with low levels of racial prejudice. Our second study revealed that participants who had qualities strongly associated with Obama as a political figure (e.g., president) activated when they were primed with “Black” had lower levels of implicit prejudice. These findings indicate that the extensive exposure to Obama resulted in a drop in implicit bias. 相似文献

The purpose of this study was to examine non-suicidal self-injury (NSSI) recovery through the lens of the transtheoretical model of stages of change. To do this, a content analysis of online posts about NSSI from 73 participants (Mage = 19.4; SDage = 5.49) with a history or NSSI was performed. Specifically, two rubrics were used. The first examined stages of change and the other positive and negative views toward NSSI recovery. Results indicated that a preponderance of posts was in the precontemplation (39.7%) and contemplation (52.1%) stages. Individuals in the contemplation stage mentioned significantly more disadvantages than advantages to change compared to those in the precontemplation stage. Overall, the current study provides preliminary evidence for the utility of stages of change when conceptualizing NSSI recovery. Implications for research and practice are addressed. 相似文献

Problem: The aim of this article was to demonstrate the influence of “Core Self-Evaluations” (CSEs) on the perception which drivers have of the occurrence of a “traffic accident”, in particular the evaluation of its likelihood, of the personal control exercised and its undesirability (attitude). More generally, this article introduces the concept of CSE in the field of driver psychology and discusses its relevance. Method: 201 French drivers replied to a questionnaire measuring CSEs, the perceived likelihood of having an accident, attitude and perceived personal control. Results and discussion: The more positively drivers evaluated themselves, the more they judged that they were in control and that accidents were unlikely. Drivers with a negative self-evaluation had an attitude more negative than drivers with positive CSEs solely when they judged the accident as unlikely. This positive correlation between attitude and perceived likelihood for drivers with negative CSEs could be viewed as the result of “wishful thinking” or “rationalisation” modes of reasoning. For these drivers a positive relationship was also observed between driving experience and perceived personal control, the latter thus cancelling out the effect of CSEs. This result suggest that with experience self-evaluation as a driver becomes positive and compensates for the effect of a negative general self-evaluation on perceived personal control and perceived likelihood. Practical implications: Using and adapting the Experience-Based Analysis technique for each group of drivers (positive or negative CSEs) is recommended, as well as implementing interventions that triggers drivers’ awareness of CSEs influence and that promote their self-regulating skills. 相似文献

Variable speed limits (VSL) are used more commonly around the globe lately. Although on a macroscopic level positive effects of VSLs have been reported, the caveat is that the impact of VSLs is very sensitive to the level of driver compliance. Thus far it is unknown whether all individual drivers are actually able to notice when a speed limit changes into another speed limit; a prerequisite for purposeful speed limit compliance in the first place. To simulate regular driving conditions, twenty-four participants were familiarised with a particular route by driving the same route in a driving simulator nineteen times on five separate days. Part of the route consisted of a motorway where VSL signs were regularly displayed above every driving lane. At drive nineteen, speed limits changed from 80 km/h to 100 km/h on four out of eight consecutive signs. After passing all signs, one expects 6.25% of the participants still to be unaware that the speed limit had increased (based on chance), while the results showed most participants had failed to notice the speed limit change (58.3%). Instead, they saw what they expected to see: a speed limit of 80 km/h. If the speed change had been vice versa, in other words from 100 km/h to 80 km/h, this would immediately result in speed offences, though not deliberately at all. 相似文献

Recent studies speculated that two types of change detection exist, one involving the experience of seeing dynamic change (change over brief interval), the other involving detecting a completed change (change over long interval), with only the former requiring sustained attention. To examine this supposition, a flicker change detection task was conducted in which the spatial location of objects was manipulated (shift, no-shift). In shift conditions, changed image display appeared in different locations than they did in the original display. The time interval separating images was manipulated (200 or 1000 ms). Results showed that a shift led to poor change detection only in the short interval condition. The performance decline by the image shift was not attenuated even when participants knew beforehand whether or not a shift would occur. Results indicate that sustained attention, which is sustained for a brief time, is related to the experience of seeing dynamic change. 相似文献

Visual working memory (VWM) has been found to support a very limited representation of visual information and yet relatively little is known about the mechanisms that underlie this important cognitive construct. Prior investigations have revealed that VWM performance can be affected by relatively minor changes in the test method as well as the method of encoding. In the present two experiments, we separately investigated these two factors. The results suggest that sequential object displays can improve VWM performance significantly but that a lack of context relatedness between encoding and retrieval impairs performance. This impairment seems to be caused by a mismatch in the spatiotemporal configuration of the memory and test displays, and, importantly, cannot be compensated by selective attention. These findings suggest that spatiotemporal configuration information may be a fundamental component of the information that is stored in VWM as suggested by a number of influential theories. 相似文献

Tracking of multiple moving objects is commonly assumed to be carried out by a fixed-capacity parallel mechanism. The present study proposes a serial model (MOMIT) to explain performance accuracy in the maintenance of multiple moving objects with distinct identities. A serial refresh mechanism is postulated, which makes recourse to continuous attention switching, a capacity-limited episodic buffer for identity-location bindings, indexed location information stored in the visuospatial short-term memory, and an active role of long-term memory. As identity-location bindings are refreshed serially, a location error is inherent for all other targets except the focally attended one. The magnitude of this location error is a key factor in predicting tracking accuracy. MOMIT’s predictions were supported by the data of five experiments: performance accuracy decreased as a function of target set-size, speed, and familiarity. A mathematical version of MOMIT fitted nicely to the observed data with plausible parameter estimates for the binding capacity and refresh time. 相似文献
