As a counterpart to research showing relationships between parental behaviors and attitudes and children's divergent thinking, this study investigated mothers’ teaching techniques and preschool children's ideational fluency, one aspect of creativity. Twenty mother‐child dyads were videotaped interacting in both a warm‐up and structured teaching session. Mothers’ teaching behaviors were assessed with the Maternal Teaching Observation Technique (MTOT) and children's ideational fluency was measured with the Multidimensional Stimulus Fluency Measure (MSFM). Correlational analyses indicated relationships between children's divergent thinking and mothers’ use of verbal negative feedback (r = .51), physical control (r = ‐.40), and visual cues (r = ‐.44).  相似文献

Orientation toward one's surroundings is necessary for prospective control of action, and constraints on orienting activity have consequences for animal survival. Physically coupled load is a constraint for humans wearing protective equipment (firefighters, soldiers, etc.). The consequences of load on postural affordances while transitioning to upright stance was used to quantify the impact of different soldier configurations. Eight participants established upright posture in 4 relevant load configurations (5.0 to 79.2 lb). Load affected the accessibility of optical information at a distance as evidenced by increasing downward head angles and reductions in postural coordination. Reductions in the variability of time to establish upright stance with load suggests a loss of functional adaptability. Load asymmetries played a significant role as the most asymmetric configuration (not the heaviest) had the most detrimental effect on postural affordances. Center of Pressure (CoP) dynamics reflected the consequences of asymmetric loading on postural regulation as greater power and fluctuations across frequencies were observed. Physically coupled load induces significant constraints on orienting activity, and load asymmetry contributes significantly to the detrimental effects of protective equipment on action-perception coupling during whole-body movements.  相似文献

A general theory of locomotor behavior in relation to physical objects is presented. Since the controlling stimulation for such behavior is mainly optical, this involves novel assumptions about object perception and about what is called visual kinaesthesis. Evidence for these assumptions is cited. On the basis of this theory it is possible to suppose that animals are visually oriented to the surfaces of their environment, not merely to light as such. In short, it is possible to explain why they seem to have space perception. Implications of this approach for maze-learning are pointed out.  相似文献

Traditional theories of psychology define the cognitive system as composed of insular, encapsulated components, controlled by a central executive. An alternative hypothesis suggests that cognitive control arises from the complex interaction among temporal scales of activity within the system. We examined the hand motions of preschool-age participants gathered during an executive-function task, card sorting, for evidence of multiplicative interactions across temporal scales. The time series of hand motions were submitted to iterated amplitude adjusted Fourier transformation (IAAFT), a surrogate data analysis technique that removes nonlinear, multiscale dependencies while preserving the linear structure of the time series. We found that removing multiscale effects via IAAFT led to a significant change in the width of the multifractal spectrum, an indicator of multiplicative interactions. The results suggest that cognitive control may arise from the interactions among temporal scales of activity within the system rather than as the result of a central executive.  相似文献

Abstract

The present paper provides a conceptual basis for the examination of mood in sport. The nature of the mood construct is discussed with reference to related constructs. A conceptual model is presented which proposes that certain mood dimensions interact to influence behavior. Depression is proposed to be the most important mood dimension, influencing the intensity of mood responses, the interrelationships among other mood dimensions, and moderating mood and performance relationships for anger and tension. It is hoped that the conceptual model will help guide applied interventions and will act as a catalyst for future research.  相似文献

In this study, self-determination theory was used as a guiding framework to understand the putative role of relatedness support for retention in golf among young females. Data were collected using semi-structured interviews with 10 female participants (Mage = 21.40, SD = 3.13). Content analyses revealed 5 distinct factors that contributed to the provision of relatedness support: Parents, Peers, Coaches, Golf Club, and Institutional and Societal Support. Findings highlighted that retention of female golfers may be facilitated through promoting valued relationships with parents, peers, coaches, and golf clubs. Policies that decrease the perceived marginalization of female participants may also be perceived as a form of relatedness support and may promote retention within this cohort. This study underscores the importance of relatedness support for young women and identifies strategies that may help to improve female retention in sport.  相似文献

Abstract

This article reviews the major social cognitive models of adherence or compliance in health and exercise behavior and attempts to show that these models are more similar to each other than different from each other. Self-efficacy theory and the theory of reasoned action/planned behavior have guided most of the theory-based research on exercise behavior. Two other models, protection motivation theory and the health belief model, have guided much research on the role of social cognitive factors in other health behaviors. These models are comprised largely of the same basic set of social cognitive variables: self-efficacy expectancy, outcome expectancy, outcome value, and intention. Two other factors, situational cues and habits, although not common to all the models, round out the theoretical picture by explaining how the relationship between the major social cognitive variables and behavior may change with repeated performance of a behavior over time.An integration of these models is offered using the theory of planned behavior as a foundation. It is suggested that research on health and exercise behavior that pits one model against another to determine which one is the better predictor of behavior is likely to be unproductive due to the striking similarities of the models. It is suggested instead that theorists and researchers focus their efforts on integration of the major social cognitive models and on determining the relative predictive utility of the various social cognitive factors with various health behaviors and in various contexts.  相似文献

This author argues that therapeutic action in child psychoanalytic psychotherapy rests with the creation and transformation of fantasy through play, which in turn shifts psychic structure. The paper details the treatment of an eight-year-old girl whose mother's inability to playfully participate in the inner world of her child interfered with the child's development of a fantasy life. The author suggests that the introduction of objective reality (i.e., interpretations that link the child's play with the real world) potentially impinges on and interferes with the transformational processes of fantasy. Developing the capacity to distinguish reality from fantasy does not take place through a forced accommodation to reality, but rather through the expansion of fantasy and a widening of the realm of the imagination. The elaboration of fantasy in concert with a parent or analyst is what builds the child's capacity to differentiate reality from fantasy.  相似文献
