ObjectivesTwo studies were conducted to evaluate the reliability and predictive validity of measures of intrinsic and extrinsic motivation for exercise, and to examine differences in motivation as a function of stage of motivational readiness for exercise.DesignA cross-sectional design was employed in study one, and a longitudinal design was used in study two.MethodsIn study one, 184 healthy college students completed instruments to measure motivation and exercise stage. Intrinsic and extrinsic motivations were factor analyzed into subscales and validated in study two on a second sample of college students (n=220) by analyzing shifts in endorsement of motivation subscales from the beginning to end of the academic term.ResultsIn both samples, intrinsic motivation for exercise was most highly endorsed in maintenance and lowest in contemplation stage. All extrinsic motivation subscales except tangible rewards were also most highly endorsed in maintenance compared to other stages. In study two, students in activity classes (n=72) endorsed both intrinsic and extrinsic motivation more than those in lecture classes (n=70). Relative to patterns of physical activity, intrinsic motivation was greater than extrinsic motivation for the continually active group, and decreased for the continually inactive group. Exercise maintenance was fostered by greater intrinsic relative to extrinsic motivation.ConclusionIntrinsic and extrinsic motivation can be decomposed into meaningful subfactors that are differentially related to exercise adoption and maintenance.  相似文献

Evaluation of acceptability and preliminary efficacy of an Internet and short message service (SMS) intervention for promoting physical activity (PA) in Hong Kong Chinese school children. An 8-week quasi-experimental study non-randomly assigned 78 school children (mean age=12.8 years) to (a) an intervention group that received a stage-matched, Internet PA program two times a week and tailored SMS messages daily; or (b) a no-treatment control. Data were collected from September 2008 until June 2009. Acceptability measures included exposure rate and participant's satisfaction. Efficacy measures were changes in stage of motivational readiness (SMR) and self-reported PA level. Intervention participants demonstrated significant pre-post increments in SMR (Z=-2.558, p=0.011) and self-reported PA level [F(1, 76)=4.50, p=0.04]. There was a non-significant trend between groups in both SMR (p=0.24) and PA (p=0.13). Despite the similar ratings of satisfaction between Internet (M=3.12±0.74) and SMS (M=3.12±0.84), participants displayed distinct patterns of exposure with 66% exhibiting a weekly login rate of 0.5 times/person and an average of 3.75 minutes/visit/person. In contrast, 79% of participants read an average of 1.3 SMS/person/week and 47% voluntarily replied to ~3.8 SMS/person. These findings demonstrate the acceptability and preliminary efficacy of an Internet-SMS-based intervention for promoting PA in Hong Kong school children. The divergent exposure rates between the Internet and SMS may be a unique pattern for adolescents in early SMR. Future research should be cognizant of the importance of SMR since it may influence utilization and/or adherence.  相似文献

Previous research indicates that attitudes can form via the implicit (unconscious) detection of covariations between attitude objects and other valenced stimuli (Olson & Fazio, 2001, 2002). We posit that due to the lack of awareness of their origins, attitudes resulting from implicit evaluative conditioning are more affective in nature and resemble gut intuitions more than rational beliefs. This suggests that circumstances exist when individuals will be more likely to express implicitly-formed attitudes, and across a correlational study and 2 experiments, the present research demonstrates factors that increase conditioning-consistent decision-making. Specifically, we demonstrate that feelings of intuitiveness and expertise, both of which can foster a sense that one can “trust one's gut,” lead one to express attitudes recently formed through an implicit evaluative conditioning procedure. We conclude that while implicit attitude formation may be a pervasive phenomenon, implicitly formed attitudes may be expressed only under certain conditions.  相似文献

People routinely engage in dishonest acts without feeling guilty about their behavior. When and why does this occur? Across four studies, people justified their dishonest deeds through moral disengagement and exhibited motivated forgetting of information that might otherwise limit their dishonesty. Using hypothetical scenarios (Studies 1 and 2) and real tasks involving the opportunity to cheat (Studies 3 and 4), the authors find that one's own dishonest behavior increased moral disengagement and motivated forgetting of moral rules. Such changes did not occur in the case of honest behavior or consideration of the dishonest behavior of others. In addition, increasing moral saliency by having participants read or sign an honor code significantly reduced unethical behavior and prevented subsequent moral disengagement. Although dishonest behavior motivated moral leniency and led to forgetting of moral rules, honest behavior motivated moral stringency and diligent recollection of moral rules.  相似文献

Reinforcement learning approaches to cognitive modeling represent task acquisition as learning to choose the sequence of steps that accomplishes the task while maximizing a reward. However, an apparently unrecognized problem for modelers is choosing when, what, and how much to reward; that is, when (the moment: end of trial, subtask, or some other interval of task performance), what (the objective function: e.g., performance time or performance accuracy), and how much (the magnitude: with binary, categorical, or continuous values). In this article, we explore the problem space of these three parameters in the context of a task whose completion entails some combination of 36 state-action pairs, where all intermediate states (i.e., after the initial state and prior to the end state) represent progressive but partial completion of the task. Different choices produce profoundly different learning paths and outcomes, with the strongest effect for moment. Unfortunately, there is little discussion in the literature of the effect of such choices. This absence is disappointing, as the choice of when, what, and how much needs to be made by a modeler for every learning model.  相似文献

Objective: This study investigated the role of coping plans and the use of selection, optimisation and compensation (SOC) strategies within an experimental evaluation of a 26-week physical exercise intervention.

Methods: Older women (N?=?86, M age?=?73.7 years) were randomly assigned to a telephone-assisted or a self-administered coping planning intervention after 6 weeks’ participation in an exercise programme. The number of different coping plans formulated, exercise-specific SOC strategy use and their interaction were used to predict objectively measured long-term adherence to the intervention.

Results: The number of coping plans formulated (β?=?0.28) and goal-pursuit strategies reported (sum score of optimisation and compensation strategies, β?=?0.39) predicted adherence to the exercise programme over 20 weeks. The predictive strength of coping plans increased with decreasing numbers of goal-pursuit strategies (β?=??0.21). Women supported via telephone reported significantly more coping plans than did women in the self-administered coping planning group, F(1,80)?=?9.47, p?=?0.003.

Conclusion: Coping plans have a buffering effect on adherence levels when use of SOC strategies is low. Older women's adherence to physical activities may be improved if they are given direct support in generating coping plans involving strategies of selection, optimisation and compensation.  相似文献

Physical activity is associated with many benefits, but persons with multiple sclerosis (MS) are less physically active than the general population. There is a critical need for research on methods of increasing and sustaining the physical activity levels of this population. This randomized controlled trial examined the efficacy of an Internet-delivered and theory-based behavioral intervention that was supplemented with video coaching for increasing and sustaining physical activity over time in persons with MS. Physically inactive, ambulatory persons with MS (N?=?45) were randomly assigned to intervention (n?=?22) or control (n?=?23) conditions and completed a battery of questionnaires before, after, and three months after a 12-week intervention period. Data analyses were conducted in PASW 18.0. Partial eta squared ([Formula: see text]) effect size indicated that there was a large, statistically significant condition-by-time interaction on physical activity ([Formula: see text]). Cohen's d effect sizes indicated that the intervention group had a large increase in physical activity after the 12-week trial (d?=?.98) that was sustained over a three-month follow-up (d?=?.79). The current study supports the efficacy of a behavioral intervention for increasing and sustaining physical activity in a sample of persons with MS.  相似文献

Transference has generally been discussed in terms of its operating to distort the way in which a current relationship is dealt with and experienced because of one's past. In the present paper, emphasis is placed on that aspect of transference which operates as a defense, and which is called into play in response to signal anxiety associated with a "pathogenic complex" and is based on (1) a traumatic experience of stimulus overload or (2) an intrapsychic conflict stemming from instinctual drive pressure which in turn threatens a repetition of the traumatic experience. Clinical illustrations are presented in which both traumatic experience and drive-conflict forces are prominent, leading to a discussion of the here-and-now versus reconstruction of the past, as well as affective/cognitive and interpersonal/intrapsychic factors.  相似文献

This study explored how causality orientations, individual differences in imagery, and reward contingency are related to performance and intrinsic motivation. Cognitive evaluation theory, as applied to both causality orientation and reward contingency, was used to make predictions about the effects of internal or external events perceived as being autonomy supportive or controlling. In the light of the fact that task-contingent rewards must be salient to undermine intrinsic motivation and performance, one can suppose that high imagery may increase the controlling aspects of task-contingent rewards. Moreover, research now indicates that vegetative activation correlates with levels of imagined effort, and that high imagery capabilities enhance performance in motor skills. The main purpose of this study was to contribute some arguments for imagery and reward interaction effects on intrinsic motivation and performance. As predicted, autonomy-oriented subjects reported more interest and intrinsic motivation, and exhibited better performance than did control-oriented individuals. Similar differences were observed in favour of high-imagery individuals. Moreover, the effects of imagery were not only subject to an interaction between imagery and causality orientation, but also between imagery and reward contingency. The links between these variables are discussed in the framework of both Carver and Scheier's (1981) motivational control theory, and Deci and Ryan's (1985a) cognitive evaluation theory. © 1998 John Wiley & Sons, Ltd.  相似文献

Responses to projective material by neurotically and psychotically depressed patients were scored for fluency, movement, and primary process during light physical activity and inactivity. A depression measure was also obtained. Significant positive correlations were found between fluency, movement, and primary process. Movement scores did not increase significantly during physical activity for either group. No significant correlations were found between level of depression and production of movement and primary process. However, primary process, controlled for fluency, increased significantly during physical activity for neurotic, but not for psychotic depressives.  相似文献

ObjectivesThe role of physical activity (PA) in the promotion of mental wellbeing and prevention of psychological disorders in population groups at increased risk for mental health conditions, such as migrant populations, has never been systematically investigated.MethodsWe conducted a systematic review and meta-analysis according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), Pubmed, Web of Science, SportDiscus. We included randomized (RCTs), controlled clinical trials (CCT), and pre-post intervention studies, that assessed the efficacy of PA interventions in migrants, compared with any types of controls.ResultsWe included 27 studies (4166 participants) (16 RCTs; 2 CCTs; 9 pre-post design) between 1997 and 2020. Meta-analysis showed a significant beneficial effect of PA over control conditions for general functioning (SMD -0.35, 95% CI -0.83 to −0.16; 400 participants), outcome expectancies (SMD -0.78, 95% CI -1.17 to −0.40; 118 participants), self-efficacy/coping (SMD -0.28, 95% CI -0.52 to −0.03; 269 participants), and psychological symptoms (SMD -0.48, 95% CI -0.88 to −0.08; 6 RCTs; 597 participants). Similar findings were produced by pre-post intervention studies (SMD -0.35, 95% CI -0.60 to −0.10; 7 studies; 302 participants).ConclusionsMigrant populations may benefit from PA interventions to improve psychological outcomes. Uncertainty remains about the best approach to promote PA in this population, and future research should consider the complex factors that characterize the migration experience.  相似文献

Objectives

This intervention study evaluated the effects of exercise in old age on views on one’s own aging and on direct approach motivation for physical activity. It further examined the mechanism between these variables.

Design

Two hundred forty-seven healthy women aged 70−93 years were randomized to an exercise course (n = 86), an active (n = 85), or a passive control group (n = 76) for a 6-month participation in Berlin, Germany. Activity interventions (3 × 1.5 h/wk) were conducted using standardized manuals.

Method

Group differences in changes of views on aging and direct approach were evaluated by analyses of covariance adjusted for baseline. A mediating effect of direct approach between exercise participation and views on aging was tested with percentile-based bootstrapping.

Results

In contrast to both the active and the passive control groups, higher direct approach, F(2, 226) = 6.97, p = .001, and less aging dissatisfaction, F(2, 225) = 5.39, p = .005, were observed in the exercise group after 6 months. Exercise had an indirect beneficial effect on aging dissatisfaction through direct approach, B = −0.31, 95% CI = −0.68 to −0.05.

Conclusion

In women above 70 years, exercise participation increases direct approach motivation which in turn leads to lower aging dissatisfaction. This shows that exercise holds the potential to overcome subjective ageist bias.  相似文献

We studied visual perspective of three autobiographical memories and three projected future events (i.e. whether the events were experienced from a first-person or third-person perspective, or in between) in 117 undergraduate students. Perspective proved to be a reliable individual-differences variable. The majority of narratives trended toward the first-person perspective, with memories more likely to yield first-person perspective than future events. Perspective was predicted by detail (higher level of participant-reported visual detail was more likely to elicit first-person perspective), and temporal distance (events reported as being further away in time were more likely to elicit third-person perspective). Detail, in turn, was explained (among others) by the individual-differences variable of depression/social uncertainty (a factor-derived scale consisting of rumination scales, the inverse of the Sense Of Self Scale, the Social Phobia Scale, and, to a lesser extent, the Social Interaction Anxiety Scale). Generally, predictors for memories and future events overlapped. The results underscore the need for including individual-differences variables in research on the determinants of memory perspective.  相似文献

Mental illness is associated to both metabolic and cognitive deficits. The idea here is to use adapted physical activity (APA) to help both aspects of pathology within a personal-targeted cognitive intervention program in order to enhance self-efficacy and intrinsic motivation. Using a multi-experience neuropsychological tool set (comprising touch pad exercises, wood puzzles and one-on-one semi-structured interviews), the different domains of action, timing, executive functions and social cognition were evaluated in a short 30-minute session. These computerized neuropsychological data were then used to adapt the difficulty of the proposed physical activity. Results obtained in a small group of ten patients revealed that the battery was well accepted. Both quantitative and qualitative results were collected and suggested that after 4 sessions of 2 h activity, the scores were improved for motor planning, motivation and the subjective report of quality of life. These preliminary data are important as they show that new technology can now be used to adapt automatically physical activities to the motor, cognitive and emotional capacities of the targeted individuals. Touch pads may also afford an innovating way to evaluate efficiently cognitive abilities while preserving the pleasure of the moment.  相似文献

The current paper describes the results of an experiment in which 200 students who varied in levels of trait perfectionism performed a laboratory task of varying levels of difficulty. Participants received either negative or positive performance feedback, independent of their actual level of performance. Analyses of pre-task and post-task measures of negative and positive affect showed that individuals with high self-oriented perfectionism experienced a general increase in negative affect after performing the task, and self-oriented perfectionists who received negative performance feedback were especially likely to report decreases in positive affect. Additional analyses showed that self-oriented perfectionists who received negative feedback responded with a cognitive orientation characterized by performance dissatisfaction, cognitive rumination, and irrational task importance. In contrast, there were relatively few significant differences involving other-oriented and socially prescribed perfectionism. Collectively, our findings support the view that self-oriented perfectionism is a vulnerability factor involving negative cognitive and affective reactions following failure experiences that reflect poorly on the self.  相似文献

Research indicates that death‐relevant thoughts (mortality salience) have a nuanced effect on judgments of life's meaningfulness. Thoughts of death diminish meaning in life only among people who lack or do not readily engage psychological structures that confer meaning. Building on this past research, the current research examined how an important source of meaning, long‐term goal progress, affects the ways that death‐relevant cognitions impact judgments of life's meaning. In Study 1 (N = 118), mortality salience decreased perceptions of meaning in life only among participants who were induced to feel closer to (vs. farther from) completing a long‐term goal. Study 2 (N = 259) extended these findings by demonstrating the moderating influence of individual differences in locomotion. Mortality salience again decreased perceptions of meaning in life among participants who felt closer to accomplishing a long‐term goal, but it only did so among people who do not quickly adopt new goals to pursue (i.e., those low in locomotion). The implications of these findings for better understanding how people maintain meaning in the face of existential concerns and how aspects of goal pursuit affect these processes are discussed.  相似文献

This study explored male adolescents' reasons for participating in moderate and vigorous physical activity, perceived barriers to moderate and vigorous physical activity, and suggestions as to what can be done to increase participation in physical activity. A total of 26 male 15- and 16-year-old adolescents participated in focus group sessions, which were audiotaped and transcribed verbatim; qualitative software facilitated data analysis. A constant comparison approach was used to inductively develop themes. It was found that participants engaged in physical activity for both intrinsic and extrinsic reasons. Their perceived barriers to physical activity included both internal factors (individual characteristics, lower priority for physical activity, and involvement in technology-related activities) and external factors (the influence of peers and family, lack of time, and inaccessibility and cost of facilities). Participants suggested that physical activity be promoted more in the community and that an environment more supportive of physical activity be developed. Results suggest that a variety of strategies should be used to help male adolescents maintain or increase participation in moderate and vigorous physical activity.  相似文献

Using data from a 2-year longitudinal study of 200 Black and White adolescent girls (mean age was 13.8 years at study entry), the authors investigated the implications of differences in body fat for dating and sexual activity and the implications of heterosexual activity for dieting and weight concerns. Among White girls, and Black girls with college-educated mothers, more body fat was associated with a lower probability of dating, even among nonobese girls. However, dating and sexual experience were unrelated to subsequent dieting and weight concerns. For both Blacks and Whites, body fat was the key determinant of dieting, weight dissatisfaction, and eating concerns. These findings indicate that adolescent girls' concerns about weight have a basis in real experiential differences, and efforts to promote healthy attitudes and eating habits may be more effective if the experiential implications of weight differences are taken into account.  相似文献
