Temporal focus is the attention individuals devote to thinking about the past, present, and future, and the concept is important because it affects how people incorporate perceptions about past experiences, current situations, and future expectations into their attitudes, cognitions, and behavior. However, temporal focus has not been clearly defined nor situated in a nomological network of constructs. In addition, existing measures of temporal focus suffer from various shortcomings. In this paper, we advance the concept of temporal focus by critically examining its conceptualization, developing a new measure of temporal focus (Temporal Focus Scale; TFS), and evaluating the validity (i.e., construct, convergent, discriminant, nomological, and predictive validity) of the TFS across four studies. We conclude that understanding how individuals focus their attention toward the past, present, and future clarifies their responses to explicit and implicit temporal information, which suggests that a variety of research streams would benefit from incorporating the concept of temporal focus.  相似文献

Forty-one mothers and their 12-month-old infants participated in a study of the effects of maternal control style on infant mastery motivation. Three scales were designed to assess maternal control style during a mother-infant play session. Mastery motivation was assessed in an experimenter-administered structured toy play procedure. Three components, persistence, competence, and affect, comprised the measure of mastery motivation. Mothers also completed questionnaires on child-rearing attitudes, infant temperament, and control style. Results showed that maternal attitudes and behavior were correlated with infant mastery motivation. More specifically: autonomy-oriented control behavior, sensitive care and knowledge of child-rearing were positively related to infant mastery motivation. The results provide converging evidence regarding the multiple aspects of maternal behavior which affect infant motivation.  相似文献

Feature discrimination performance within an attended object and interference from irrelevant, multi-dimensional objects (distractors) were examined in a two-choice, response compatibility paradigm. Results showed that the amount of interference by multi-dimensional distractors was dependent on three factors: (1) the discriminability of the incompatible, task-relevant distractor features; (2) the number of incompatible, task-relevant distractor features; and (3) whether the task-relevant, incompatible features matched the task goals. The most interesting finding was that additive priming effects were found for multiple, task-relevant features that matched the task goals, whether these features were present in the attended object or in the ignored object. Models that assume that each task-relevant feature primes its corresponding decision/response asynchronously and that this priming is combined to meet a decision/response criterion (at least when attended) can account for distractor interference during conjunction discriminations. Implications of these findings for feature integration models, template models, and a response selection model are discussed.  相似文献

This paper reports the results of a study examining issues of group gender composition in a meeting setting employing group support systems (GSS). Research examining the effects of numerical proportions on group behavior has traditionally been conducted in settings where use of technology by groups is minimal. This research, however, examines the impact of varying group gender composition on brainstorming, social interaction patterns, and attitudes when technology is employed to facilitate and structure group process. In this setting, we find no gender-related differences in computer-based brainstorming. In the accompanying oral discussions, however, males display a higher proportion of task-related answers than females and uniform groups express more maintenance behavior than groups consisting of mixed genders. Our findings also show that uniform gender groups perceive greater participation in the decision process than skewed groups. Despite these gender-related differences, we found relatively little support for Kanter's Numerical Proportions Model in a GSS setting, given the range of measures explored in this study.  相似文献

It is generally believed that prior to the middle to late elementary school years children's reports of anxious symptoms represent nothing more than transient developmental phenomena. In light of the limited empirical study of this issue and its import to the allocation of mental health resources, the present study seeks to provide empirical evidence of the significance of anxious symptoms in children younger than 7. Specifically, utilizing an epidemiologically defined population of 1197 first-grade children, followed longitudinally from the fall to spring of first grade, we examine the stability, prevalence and caseness of children's self-reports of anxious symptoms. Self-reported anxious symptoms proved relatively stable over 4-month test-retest interval. In addition, they appeared to have a significant impact on academic functioning in terms of reading achievement. These findings on stability, caseness, and prevalence suggest children's self-reported anxious symptoms in the early elementary school years may have clinical significance. However, further study is necessary before firm conclusions can be drawn.  相似文献

The purpose of this study was to evaluate the effects of a Spanish mental health video, “Cuida Su Salud Mental”, on the relationship attitudes and social skills knowledge of a Mexican immigrant sample. Subjects consisted of 72 Spanish speaking English as a second language (ESL) students recruited from the Paramount Adult School, in the county of Los Angeles. The Solomon (1949) Four Group Design was used. Half of the subjects were pretested on knowledge and attitudes about effective communication skills and relationships, respectively. All subjects view either the mental health video or a control video, and then were posttested on knowledge and attitudes. Results indicated that the mental healthy video (MHV) group exhibited more knowledge, F(1, 62) = 10.61, p= 0.002, and less risky attitudes, F(1, 62) = 4.29, p= 0.043, than the control video group. The MHV group also showed an increase in knowledge from the pretest to the posttest, F(1, 35) = 7.36, p= 0.01. Finally, both video groups reported a decrease in risky attitudes from pretest to posttest, F(1, 34) = 18.21, p= 0.001. These results support the use of “Cuida Su Salud Mental” as a productive and cost-effective mental health intervention that can be used to reach a large segment of the Spanish speaking community.  相似文献

Prevention of depressive symptoms in school children   总被引:9,自引:0,他引:9  
This paper describes the development and preliminary efficacy of a program designed to prevent depressive symptoms in at-risk 10–13 year-olds, and relates the findings to the current understanding of childhood depression. The treatment targets depressive symptoms and related difficulties such as conduct problems, low academic achievement, low social competence, and poor peer relations, by proactively teaching cognitive techniques. Children were identified as ‘at-risk’ based on depressive symptoms and their reports of parental conflict. Sixty-nine children participated in treatment groups and were compared to 73 children in control groups. Depressive symptoms were significantly reduced and classroom behavior was significantly improved in the treatment group as compared to controls at post-test. Six-month follow-up showed continued reduction in depressive symptoms, as well as significantly fewer externalizing conduct problems, as compared to controls. The reduction in symptoms was most pronounced in the children who were most at risk.  相似文献
