New evidence-based physical activity (PA) guidelines and recommendations for constructing messages supplementing the guidelines have been put forth. As well, recent reviews have identified theoretical constructs that hold promise as targets for intervention: self-regulation, outcome expectancies and self-efficacy. The purpose of this study was to examine the integration of messages targeting self-regulation, self-efficacy and outcome expectancies in existing physical activity brochures. Twenty-two PA brochures from Canadian and American National Health Organizations were assessed for their use self-efficacy, self-regulatory processes and outcome expectancies. Brochures were analyzed line-by-line using a modified version of the validated Content Analysis Approach to Theory-Specified Persuasive Educational Communication (CAATSPEC; Abraham, Southby, Quandte, Krahé, & van der Sluijs, 2007). Two independent raters coded a third of the brochures (n = 7). Inter-rater reliability was acceptable for 17 of the 20 categories (rs > .79). Discrepancies in all categories were discussed and agreement was reached. The remaining brochures were coded by one of the two raters. Usage of the three key theoretical constructs accounted for only 36.43% of brochure content (20.23% self-efficacy, 10.40% outcome expectancies, 5.80% self-regulation). Brochures lacked the use of a variety of theoretical strategies, specifically goal-setting, planning and verbal persuasion and rarely highlighted the affective benefits of physical activity. In the future brochures should aim to place increased emphasis on self-regulation, self-efficacy, and affective outcome expectancies.  相似文献

With growing recognition that there are universal sex differences in cognition and behavior, four theories have been proposed to account for these differences: the founder effect theory, the social structuralist theory, the evolutionary theory, and the evolutionary neuroandrogenic (ENA) theory. The latter of these theories is described in considerable detail as offering an explanation for most of 65 recently identified apparent universal sex differences (AUSDs) in cognition and behavior. Regarding “ultimate causes” (why), ENA theory asserts that (a) evolutionary-genetic factors incline females to bias their mate choices toward males who are loyal and competent provisioners of resources and (b) males are merely a genetic variant on the female sex selected for responding to female mating biases. In terms of “proximate causes” (how), the theory maintains that high exposure to androgens has evolved to alter the male brain functioning in two specific ways relative to most female brains: (a) suboptimal arousal and (b) a rightward shift in neocortical functioning. These two functional patterns are described and hypothesized to incline males and females to learn differently in many respects. The most fundamental differences involve males learning ways of either complying with or circumventing female mate preferences. Numerous universal sex differences in cognition and behavior are hypothesized to result from these evolved neurohormonal factors, including most of the 65 AUSDs herein summarized in seven categorical tables.  相似文献

Teachers and students in 39 1st, 3rd and 5th grade classrooms participated in a study of teaching practices and classroom peer networks. Teachers reported on their attitudes towards aggression and withdrawal, provided rationales for their seating arrangements, and were observed on patterns of emotional and instructional support and classroom organization. Students were surveyed or interviewed for peer nominations of friendship, popularity, being cool, and aggressive and prosocial behavior, and from these nominations classroom-level indices were derived concerning the richness of positive and negative social ties among children, the egalitarian or hierarchical nature of social status hierarchies, and classroom norms for aggressive and prosocial behavior. Preliminary results suggest that teachers' attitudes towards social behavior are associated with the degree of liking and disliking their students express; teachers' grouping patterns are associated with numerous features of classroom social networks; and teachers' observed emotional support was associated with higher rates of friendship reciprocation.  相似文献

What is behavior? And so what?   总被引:1,自引:0,他引:1  
This article addresses a longstanding problem in the field of psychology, that of lacking an adequate explication of what is arguably our central concept as a “science of behavior,” the concept of “behavior” itself. The three sections comprising the paper are devoted, respectively, to (a) presenting a conceptual formulation of behavior; (b) discussing this formulation by, among other things, addressing objections to it and noting its advantages over psychology’s currently preferred definition of behavior as observable activity; and (c) relating why having such a formulation is important. The final section includes several uses to which the present formulation has already been and can in future be put, including a sketch of how it may be used to integrate the various subfields of our currently fragmented science of behavior.  相似文献

The Theory of Planned Behavior (TPB) offers a parsimonious explanation of purposive behavior, but in the study of healthy and risk behaviors its sufficiency may be questioned. Working with binge-drinking, a very common risk behavior in Spanish undergraduate students, we used two strategies for improving predictions from TPB: using behavioral intention (BI) and behavioral expectation (BE) as proximal antecedents of behaviors and adding as new predictors two future-oriented emotions (anticipated and anticipatory). Hierarchical regression analyses show that while anticipated emotions improved TPB explanations of BI, anticipatory emotions improved the explanations of BE. The present results show the influence of future emotions in the prediction of behavioral intention and behavioral expectation.  相似文献

Although maternal sensitivity is widely understood as having a direct impact on the quality of the mother–child relationship, empirical evidence supporting this has been inconsistent, possibly because of varied definitions of the construct and limitations of measurements. The Maternal Behavior Q‐Set (MBQS) appears to be a promising measure of sensitivity, showing associations with attachment security (r = .60) higher than those reported (r = .24) in a highly‐regarded meta‐analysis of other sensitivity measures. The present study aimed to further establish the validity and utility of the MBQS by exploring its consistency with a contingency‐based measure of sensitivity, while also seeking evidence of stability across contexts and times. Seventy‐two mothers and their 10‐month‐olds participated in a procedure that included two episodes of Floor Play and Reunions following maternal differential treatment. Mothers were scored on contingent responsivity and warmth. At 12 months, the dyads underwent the Strange Situation Procedure where sensitivity was assessed using a 72‐item version of the MBQS. The findings revealed the stability of maternal sensitivity across times, contexts, and measures. However, linkages applied only to 10‐month scores from reunion, not play, episodes, supporting Pederson and Moran's (1995) assertion that high‐demand circumstances reveal more meaningful differences in maternal sensitivity.

Psychologists have placed an increased emphasis on identifying psychological strengths that foster healthy development. Hope, as operationalized in Snyder's hope theory Snyder, C. R., Hoza, B., Pelham, W. E., Rapoff, M., Ware, L., & Danovsky, M., et al. (1997). The development and validation of the children’s hope scale. Journal of Pediatric Psychology, 22, 399-421], is one such cognitive-motivational construct that has received recent attention as a potential psychological strength that may serve as a protective factor for adolescents in the face of adverse life events. This longitudinal study, involving middle and high school students, provided evidence of (1) stability of hope reports of adolescents over a 1-year period, (2) predictive validity of adolescent hope reports, and (3) hope's functional role as a moderator in the relationship between stressful life events and adolescent well-being. Taken together, the results provide support for consideration of hope as a key psychological strength in youth. The findings are consistent with theories of motivation in which individual differences in hopeful thinking are conceptualized to play a functional role in linking life events and psychological well being.  相似文献

This study investigated the relationships among school satisfaction, social support, and problem behaviors in adolescents. Modest associations were found between school satisfaction and the demographic variables of gender, race, age, and grade level. Support from teachers, parents, and classmates contributed unique variance to ratings of school satisfaction; with teacher support contributing the most unique variance. School satisfaction mediated the relationship between social support and internalizing and externalizing behaviors. School satisfaction did not moderate the relationship between social support and problem behavior; however, it did serve as a protective factor across all levels of social support. Implications are discussed, including suggestions for developing interventions that focus on increasing support for adolescents in efforts to improve school satisfaction and reduce problem behaviors.  相似文献

In a series of three experiments, prediction of exam performance from information about motivation and ability of students was studied. The factorial plot of the Motivation × Ability effect on predicted performance always yielded the parallelism pattern with subjects from both the student and nonstudent populations. Results agreed with the hypothesis of cultural difference between America and India. Manipulation of difficulty of exam did not alter the parallelism pattern, contrary to the specification of the hypothesis of task difficulty. Difficulty of exam affected only the origin of the response scale. Implications of results were discussed for the two tested hypotheses as well as for a new hypothesis of nature of task.  相似文献

A group of very low birthweight preterm infants (mean WEIGHT = 1193.6 g; mean gestational AGE = 31.1 weeks) were examined with the PREMIE. The PREMIE is a modification of the scoring system of the full term Brazelton Neonatal Behavioral Assessment (BNBAS) examination for use with preterm infants. Infants were assessed during the acute phase of cardio-respiratory illness (mean AGE = 7 days) and during the recovery phase (mean AGE = 22 days). Many modifications in procedure were required. Several analyses were performed to assess the redundancy and the comparative validity of the scoring systems of the PREMIE, the BNBAS, and the BNBAS + (the BNBAS plus a set of five additional preterm items). Results indicated that the three scoring systems were highly redundant, that they were equally related to physiologic and clinical variables, and that they were similar in their sensitivity to behavioral change and stability. Overall the results offered little in the way of differentiating among these three scoring systems with this group of infants, raising doubts about the need to use the PREMIE or other scoring systems like it for many research purposes.  相似文献
