IntroductionThis article exposes a brief history of information search models, from general and behavioural models to cognitive ones and presents recent theoretical advances in this research field.Literature findingsSince the beginning of 1990s, many theoretical models have tried to describe and predict the human behaviours involved in the information search tasks, and specifically when this activity is performed in computer systems. Some of these models elaborated by psychologists have attempted to infer the cognitive processes involved.DiscussionInformation search can be considered as a complex cognitive activity that involves various individual (cognitive, affective), contextual and social factors.ConclusionWe also suggest research issues to be developed in order to increase our knowledge in this area and we plead for further research on specific concepts depending on future and/or recent areas of interest.  相似文献

Background: Systematic reviews now routinely assess methodological quality to gauge the validity of the included studies and of the synthesis as a whole. Although trends from higher quality studies should be clearer, it is uncertain how often meta-analyses incorporate methodological quality in models of study results either as predictors, or, more interestingly, in interactions with theoretical moderators.

Objective and methods: We survey 200 meta-analyses in three health promotion domains to examine when and how meta-analyses incorporate methodological quality.

Results: Although methodological quality assessments commonly appear in contemporary meta-analyses (usually as scales), they are rarely incorporated in analyses, and still more rarely analysed in interaction with theoretical determinants of the success of health promotions. The few meta-analyses (2.5%) that did include such an interaction analysis showed that moderator results remained significant in higher quality studies or were present only among higher quality studies. We describe how to model quality interactively with theoretically derived moderators and discuss strengths and weaknesses of this approach and in relation to current meta-analytic practice.

Conclusions: In large literatures exhibiting heterogeneous effects, meta-analyses can incorporate methodological quality and generate conclusions that enable greater confidence not only about the substantive phenomenon but also about the role that methodological quality itself plays.  相似文献

IntroductionThe compliance literature describes multiple techniques of social influence. Some of them have proven effective at inducing compliance in the charity domain. One such technique is referred to as legitimizing a paltry contribution (LPC). There are theoretical grounds on which it can be assumed that this technique will be particularly effective in conditions in which a person feels relief from fear.ObjectiveThe aim of the study was to examine whether people who experience fear-relief sequences are more susceptible to the LPC technique than those in a neutral emotional state.MethodIn two field studies, some people experienced relief from fear, while others remained in a neutral emotional state. The participants were then asked to donate to a worthy cause. A request was formulated either in a standard way, or with the phrase “even a penny will help”.ResultsThe two experiments yielded consistent results. It turned out that the LPC technique was particularly effective when participants had experienced relief from fear.ConclusionsThe aforementioned pattern of results is important for the development of theoretical knowledge about techniques of social influence, and has direct practical implications.  相似文献

ObjectiveQuestionnaires are often applied in sports psychology to measure a person's trait or state. However, the extent to which the questionnaire captures differences because of trait or state influences is often unclear. The latent state–trait (LST) theory offers the opportunity to separate both variance sources. This separation allows estimating specific reliability coefficients.DesignThe present paper gives a theoretical introduction to LST and its basic ideas. Using a real data set with N = 156 athletes we exemplify the steps necessary to derive the LST coefficients. All athletes filled out a comprehensive inventory assessing competitive anxiety on two occasions.MethodThe data are analysed with structural equation models based on LST principles.ResultsThe results confirm the questionnaire's trait saturation.ConclusionFinally, results are discussed in light of practical and theoretical implications.  相似文献

IntroductionDefense mechanism and early maladaptive schemas are two concepts distorting the perception of reality.ObjectiveThe aim of this study was to explore the link between two reality-distorting concepts from two theoretical models: early maladaptive schemas from the cognitive and behavioral model and defense mechanisms based on the psychoanalytic model.MethodTwo hundred thirty-two non-clinical participants completed the Defense Style Questionnaire and the Young Schema Questionnaire (short version). Then a Bravais Pearson correlation analysis connecting these two concepts, and a multiple regressions analysis using early maladaptive schemas as predictors for defense style mechanisms levels were conducted.ResultsThe results indicate that 2 early maladaptive schema domains (i.e. other-directedness as well as over-vigilance and inhibition) predict the frequency of use of the neurotic defense mechanism, and 3 schema domains (i.e. disconnection and rejection, impaired autonomy and performances as well as impaired limits) predict the frequency of use of the immature defense mechanism.ConclusionTo conclude, two psychological concepts based on two different theoretical models (psychoanalytic and cognitive and behavioral therapy) seem to share an important link justifying the use of integrative therapies such as schema therapy.  相似文献

ProblemThere has been a recent upsurge of research interest in cognitive sport psychology or the scientific study of mental processes (e.g., mental imagery) in athletes. Despite this interest, an important question has been neglected. Specifically, is research on cognitive processes in athletes influential outside sport psychology, in the “parent” field of cognitive psychology or in the newer discipline of cognitive neuroscience?ObjectivesThe purpose of this paper is to explore the theoretical significance of research on expertise, attention and mental imagery in athletes from the perspective of cognitive psychology and cognitive neuroscience.MethodFollowing analysis of recent paradigm shifts in cognitive psychology and cognitive neuroscience, a narrative review is provided of key studies on expertise, attention and mental imagery in athletes.Results and conclusionsThis paper shows that cognitive sport psychology has contributed significantly to theoretical understanding of certain mental processes studied in cognitive psychology and cognitive neuroscience. It also shows that neuroscientific research on motor imagery can benefit from increased collaboration with cognitive sport psychology. Overall, I conclude that the domain of sport offers cognitive researchers a rich and dynamic natural laboratory in which to study how the mind works.  相似文献

Abstract

We offer a theoretical framework for treating Internet infidelity that employs concepts from postmodernism and transgenerational therapy. With this framework, clinicians will better understand some of the definitional issues and system dynamics involved, which should support more informed, coherent treatment of Internet affairs.  相似文献

IntroductionAcademic failure and dropout are pervasive challenges at all levels of the education system. Research so far pointed out different aspects of this large phenomenon. On the one hand, some scholars have argued that social support is a key factor to foster learning and persistence. On the other hand, some other scholars have rather highlighted the role of student motivation and engagement itself in improving performance on academic tasks. In this article, we tested theoretical models that combine the two approaches in a whole process.AimsWe aimed at clarifying (1) the specific contribution of several sources of perceived social support to academic performance, and (2) the mediation role of motivation and engagement in the relationships between perceived social support and performance.MethodThe sample consisted of 226 last year university students. Structural equation modeling analyses were used to test the hypothesized associations.ResultsStructural equation modeling analysis revealed that institutional and supervisor support were associated with motivation, which in turn predicted greater behavioral, cognitive and emotional engagement. Further, behavioral engagement was the unique contributor of academic performance at the master's thesis.ConclusionThe results clarify the specific contribution of different sources of perceived social support and underline the importance of the supervisor and the institution. They also underline the importance of considering different sources of perceived social support at the same time. Finally, theoretical assumptions concerning the mediational role of motivation were confirmed.  相似文献

Objective: Behaviour change interventions are effective in supporting individuals to achieve clinically significant weight loss, but weight loss maintenance (WLM) is less often attained. This study examined predictive variables associated with WLM.

Design: N-of-1 study with daily ecological momentary assessment combined with objective measurement of weight and physical activity, collected with wireless devices (Fitbit?) for six months. Eight previously obese adults who had lost over 5% of their body weight in the past year took part. Data were analysed using time series methods.

Main outcomes measures: Predictor variables were based on five theoretical themes: maintenance motives, self-regulation, personal resources, habits, and environmental influences. Dependent variables were: objectively estimated step count and weight, and self-reported WLM plan adherence.

Results: For all participants, daily fluctuations in self-reported adherence to their WLM plan were significantly associated with most of the explanatory variables, including maintenance motivation and satisfaction with outcomes, self-regulation, habit, and stable environment. Personal resources were not a consistent predictor of plan adherence.

Conclusion: This is the first study to assess theoretical predictions of WLM within individuals. WLM is a dynamic process including the interplay of motivation, self-regulation, habit, resources, and perceptions of environmental context. Individuals maintaining their weight have unique psychological profiles which could be accounted for in interventions.  相似文献

IntroductionFirst studied in adults, the concept of burnout was recently extended to adolescents in order to evaluate the impact of school requirements on their health.ObjectiveThis study aim at assessing construct validity, reliability and concurrent validity of a French version of the School Burnout Inventory (Salmela-Aro, Kiuru, Leskinen, & Nurmi, 2009) that characterize school burnout by exhaustion linked to school demands, cynicism toward school and feelings of inadequacy as a student.MethodThree hundred and eighty-seven adolescents have filled the translated questionnaire and a confirmatory factor analysis was performed on the data.ResultsThe analysis confirmed the tridimensional structure of the scale and mainly show satisfactory psychometric qualities.ConclusionThis measurement scale should provide clinicians with a rapid and simple assessment of school burnout in adolescents. Researchers could also benefit from it in order to extend theoretical knowledge about this trouble.  相似文献

Abstract

This paper is a response to Eiser's (1996) call for a unifying theoretical perspective that would bridge the gap between 'individualistic and ‘social’ approaches to studying human social behaviour in general, and health behaviour in particular. While agreeing with Eiser's premise that it makes no sense to study cognition, affect, and behaviour independently of social context, the present paper takes issue with certain features of his argument that a connectionist approach provides the needed unifying theoretical framework. It is suggested that if connectionism can describe the psychological processes underlying social behavior better than non-connectionist theories, this would provide more compelling evidence of its value than claims that it affords new theoretical insights.  相似文献

ABSTRACT

In this short contribution, I reflect on three domains I think are important to advance emotion research. The first concerns theoretical progress, which I hope will occur in the form of theoretical unification that will allow for a consensual definition and understanding of its main object of study. The second concerns measurement where in parallel to technological advances to measure behaviour and biology, particularly the measurement of experience deserves more attention. The third concerns reality, where I advocate the need to study real-world phenomena.  相似文献

ObjectivesAlthough the effect of exercise on cognitive functioning has received considerable empirical and theoretical attention, the influence of concurrent exercise on complex cognitive function remains poorly understood. Our research was designed to investigate working memory during a bout of dynamic exercise.DesignAn experimental design was used.MethodsIn two experiments, we examined the impact of moderate intensity exercise on performance of a paced auditory serial addition task (Experiment 1, N = 24) and a Sternberg task (Experiment 2, N = 120). The tasks were performed at rest and while cycling at different power outputs.ResultsWe found that moderate intensity exercise increased the number of correct responses at medium-to-fast stimulus presentation rates during the paced auditory serial addition task and lowered the response latency slopes during the Sternberg task.ConclusionsOur findings show that working memory is improved by dynamic exercise at moderate intensities and short duration.  相似文献

ObjectiveActivating negative age stereotypes has been consistently shown to impair cognitive performance in older adults, but not motor performance, especially on mobility tasks. We tested the hypothesis that older adults may still experience stereotype threat, even if mobility performance is not affected. To do so, we examined whether inducing negative stereotypes may increase cognitive load during a walking task.MethodThis question was investigated in a dual-task paradigm: older adults performed simultaneously a walking task and a Stroop task, in stereotype and control conditions.ResultsResults showed that the stereotype induction did not affect walking parameters but decreased performance on the Stroop task, indicating that this induction increased cognitive load during walking.DiscussionThese results suggest that negative age stereotypes may be damaging even if walking parameters are not affected, by altering older adults' attention to their walking environment. We conclude by highlighting theoretical and practical implications.  相似文献

ObjectivesIt has been suggested that the lack of knowledge regarding the mechanisms responsible for behavior change may be responsible for the low levels of effectiveness in physical activity interventions among youth. While it is common for physical activity interventions to cite a theoretical framework, few test the validity of their constructs using an established mediation analysis technique. The purpose of this study was to identify mediators of physical activity behavior change in two tailored interventions for adolescent girls.DesignThis study involved an experimental design.MethodsParticipants (N=161) were randomly allocated to a control (CON) group, an intervention based on the Health Promotion (HP) Model or an intervention developed from the HP Model that included two processes from the Transtheoretical Model (THP). Both interventions included school-based education sessions, individual counseling sessions, and two physical activity sessions completed with the participants' mothers. Measures were assessed prior to the intervention, at post-intervention and at a 6-month follow-up. The following constructs were included in the mediation analyses: perceived benefits, perceived barriers, self-efficacy, exposure to models, social support, interpersonal norms, planning, stimulus control, and counterconditioning.ResultsPerceived benefits, perceived barriers, self-efficacy, and commitment to planning satisfied the criteria for mediation in the THP intervention. Self-efficacy and commitment to planning were identified as mediators in the HP intervention.ConclusionThe results of this study provide evidence that both interventions were successful in increasing physical activity through changes in the theoretical constructs.  相似文献

Abstract

This article reviews psychodynamic theoretical claims linking childhood losses to depression later in life and explores contemporary empirical studies that are congruent with those claims. Biologically mediated responses to grief, empirically supported pathways that link loss to depression, and factors that distinguish normal from pathological grief are identified. Trajectories that may lead to the development of psychotic-like, instead of neurotic-like, symptoms of depression are also explored, and empirically supported internal and external vulnerability factors that may lead to depression are reported. Several clinical vignettes are included to exemplify theoretical claims. Implications for assessment and treatment are discussed in light of these findings.  相似文献

IntroductionThe low-ball (Cialdini et al., 1978)1 is a compliance-gaining technique consisting of making an attractive initial offer to get a person to agree to the request and then making the terms less favorable (target request).Objective and methodsThe effectiveness of this technique was evaluated in a meta-analysis using 17 references, 23 studies, 44 subgroups and a combined sample size of 4733.ResultsAnalysis reported a weighted mean correlation coefficient of r = .16 and a weighted mean odds ratio of OR = 2.47. Moderator analysis reported that the low-ball was more efficient with a high cost request in terms of effort for the participant and when the solicitation of the target request is deferred.ConclusionThese findings appeared congruent with commitment theoretical explanation of the low-ball.  相似文献

ObjectivesThe purpose of this paper is to provide a critical introduction on Second-Generation Mindfulness-Based Interventions (SG-MBIs) to sport and performance psychology scholars and practitioners.MethodThis essay is written as a commentary on Roychowdhury et al.’s, (2021, this issue) article in this issue. Specifically, I apply theoretical insights from Roychowdhury et al., (2021, this issue) to the practical model of SG-MBIs.ResultsI find that SG-MBIs attempt to respond to ethical concerns with the ways that mindfulness has been commodified, secularized, and universalized through appeals to cultural authenticity.DiscussionWhile acknowledging the cultural contexts from which practices like mindfulness have been taken is important, appeals to cultural authenticity often reproduce fixed and essentializing constructions of culture and are easily coopted by neoliberal multiculturalism.ConclusionAs sport and performance psychology professionals reflect on the next generation of mindfulness-based interventions, it will be important to attend to the contextual flexibility of neoliberalism to universalize and essentialize.  相似文献

IntroductionAchievement goals and attribution theory are theoretically and empirically linked, but existing literature lacks to explore the link between achievement goals and attributional retraining (AR), a motivational intervention based on the causal attribution theory.Objective(s)The aims of this field study were to determine the effectiveness of an AR treatment aimed to restructure college students’ dysfunctional causal explanations of poor performance and to explore whether achievement goals are predictive of the use of adaptive causal attributions.MethodsStudents’ achievement goals orientation and causal attributions were assessed and AR treatment was provided to a sample of second-year college students with maladaptive attributional schemas.ResultsFindings confirmed the effectiveness of AR treatment in restructuring self-defeating stable attributional explanations and suggested that achievement goals are implicated in the adoption of adaptive causal dimensions.ConclusionThe importance of integrating the two discussed theoretical models in order to provide efficacious AR interventions with students at risk is discussed.  相似文献

Abstract

Objective: Because the working memory (WM) has a limited capacity, the cognitive reactions towards persuasive information in the WM might be disturbed by taxing it by other means, in this study, by inducing voluntary eye movements (EMi). This is expected to influence persuasion.

Methods: Participants (N?=?127) listened to an auditory persuasive message on fruit and vegetable consumption, that was either framed positively or negatively. Half of them was asked to keep following a regularly moving dot on their screen with their eyes. At pretest, cognitive self-affirmation inclination (CSAI) was assessed as individual difference to test possible moderation effects.

Results: The EMi significantly lowered the quality of the mental images that participants reported to have of the persuasive outcomes. With regard to self-reported fruit and vegetable consumption after two weeks, EMi significantly lowered consumption when CSAI was high but it significantly increased consumption when CSAI was low.

Conclusions: The results verify our earlier findings that induced EM can influence persuasion. Although it remains unclear whether the effects of EMi were caused by disturbing mental images of persuasive outcomes or self-regulative reactions to these images, or both, the WM account may provide new theoretical as well as practical angles on persuasion.  相似文献
