Male goalkeepers of intermediate skill level attempted to stop penalty kicks executed with the instep and inside foot, in
situ. A mobile eye tracker and an external camera were used to collect the gaze and motor behaviors of the goalkeepers, as
well as the penalty takers’ motor behaviors and flight of the ball. Percent saves was greater during instep (28%) than inside
foot kicks (12%), but we detected few differences in fixation frequency, location, duration, or transitions that could be
attributed to the type of kick used. Fixation transitions (or the frequency of gaze shifts between locations) were significantly
higher on goals than on saves. During the final phase of the kicking action, the quiet eye was located on the visual pivot
and was longer during saves than goals. Furthermore, when the final fixation on the ball exceeded approximately 1,100 ms,
then the likelihood of goals increased. The results are discussed in light of past studies in goaltending and the dual demands
of motor tasks that require information be fixated both early and late at spatial locations that exceed the limits of focal
vision. 相似文献

The empirical finding that school-aged children could suffer clinical depression refuted the widely held assumption that this age group would be too developmentally immature to experience depressive symptoms. Currently childhood depression is a well-recognized and widely treated clinical disorder. Following more recent developmental findings emphasizing the emotional sophistication of very young children, scientific studies have demonstrated that depression can arise early in life, during the preschool period of development. Preschool depression is characterized by typical symptoms of depression such as anhedonia; changes in sleep, appetite, and activity level; and excessive guilt. Further, longitudinal continuity of preschool depression into school age has been established, suggesting that preschool depression is an early manifestation of the later childhood disorder. Based on the known efficacy of early developmental intervention in a number of domains and disorders related to the greater neuroplasticity of the brain earlier rather than later in childhood, it is important to identify depression at the earliest possible point. Early intervention strategies for preschool depression that focus on enhancing emotional development are currently being tested. 相似文献

Temporal binding via 40-Hz synchronization of neuronal discharges in sensory cortices has been hypothesized to be a necessary condition for the rapid selection of perceptually relevant information for further processing in working memory. Binocular rivalry experiments have shown that late stage visual processing associated with the recognition of a stimulus object is highly correlated with discharge rates in inferotemporal cortex. The hippocampus is the primary recipient of inferotemporal outputs and is known to be the substrate for the consolidation of working memories to long-term, episodic memories. The prefrontal cortex, on the other hand, is widely thought to mediate working memory processes, per se. This article reviews accumulated evidence for the role of a subcortical matrix in linking frontal and hippocampal systems to select and "stream" conscious episodes across time (hundreds of milliseconds to several seconds). "Streaming" is hypothesized to be mediated by the selective gating of reentrant flows of information between these cortical systems and the subcortical matrix. The physiological mechanism proposed for this temporally extended form of binding is synchronous oscillations in the slower EEG spectrum (< 8 Hz). 相似文献

The assessment of the presence and intensity of psychosocial risks is constant in research into Work Psychopathology. Many questionnaires and diagnosis systems are partial or else there is no standardization process or reliability and validity study. The main purpose of this work is to present the psychometric data of a multidimensional system to assess psychosocial risks, elaborated conjointly by the Universitat of Barcelona and the MC Mutual. This battery assesses companies, using information from the prevention technicians, the directive staff and the workers. With the diverse types of information, a triangulation proposal is established to offer a psychosocial risk profile linked to the evaluation needs. 相似文献

Two studies of college students in the US utilized a new methodological approach in which participants arranged their multiple family members (i.e. parents, siblings, aunts, and uncles) within a series of relationship network grids. These grids measured participants’ own feelings of communal responsiveness toward and perceived feelings of communal responsiveness from each family member relative to one another. The results of Study 1 (N = 86) and Study 2 (N = 111) supported the hypotheses that (1) people perceive more responsiveness from female family members than from male family members and (2) people feel more responsive toward female than toward male family members. Study 2 provided evidence that these associations were mediated by felt and perceived intimacy, dependence, and obligation, but not liking. 相似文献

2007 PRESIDENTIAL ADDRESS: FEAR OF LOSING CONTROL: POWER, PERFECTIONISM, AND THE PSYCHOLOGY OF WOMEN
Joan C. Chrisler 《Psychology of women quarterly》2008,32(1):1-12
Anecdotal evidence and popular culture suggest that fear of losing control of oneself is common among North American women, yet there is little in the way of data or theory to show why so many women fear loss of control or how to help them to leave that fear behind. In this article a commonly accepted definition of self-regulation is examined through a feminist lens to see how gender-role socialization might affect women's sense of whether and when they can regulate (or control) themselves. Particular attention is paid to eating behavior, body image, and reproductive phases (e.g., premenstrual syndrome) as areas where fears of loss of control are often expressed. Intervention points suggested here are women's standards for body and behavior; the extent of the areas that doing femininity requires them to control; and their beliefs, not only about what they can control, but what they are allowed to do. 相似文献

The currency of our visual experience consists not only of visual features such as color and motion, but also seemingly higher-level features such as causality--as when we see two billiard balls collide, with one causing the other to move. One of the most important and controversial questions about causal perception involves its origin: do we learn to see causality, or does this ability derive in part from innately specified aspects of our cognitive architecture? Such questions are difficult to answer, but can be indirectly addressed via experiments with infants. Here we explore causal perception in 7-month-old infants, using a different approach from previous work. Recent work in adult visual cognition has demonstrated a postdictive aspect to causal perception: in certain situations, we can perceive a collision between two objects in an ambiguous display even after the moment of potential 'impact' has already passed. This illustrates one way in which our conscious perception of the world is not an instantaneous moment-by-moment construction, but rather is formed by integrating information over short temporal windows. Here we demonstrate analogous postdictive processing in infants' causal perception. This result demonstrates that even infants' visual systems process information in temporally extended chunks. Moreover, this work provides a new way of demonstrating causal perception in infants that differs from previous strategies, and is immune to some previous types of critiques. 相似文献

In this longitudinal study, we compared family stories told by 32 Canadian adolescents at ages 16 and 20 about how parents and grandparents had taught them values. Relations to parents' and children's levels of generativity were also examined. Adolescents' stories of grandparent value teaching were less readily recalled and less interactive in their content compared with stories about parents. Stories of value teaching by more generative parents were more likely to involve specific episodes, to be more interactive, to be more likely to emphasize caring content, and to be less likely to have their message rejected by the teens. Similarly, when parents were more generative, adolescents' stories about grandparents' value teaching were also more likely to involve specific and interactive episodes. Finally, stories told about parents and grandparents that were more positive on these dimensions predicted higher generative concern scores for the adolescents themselves, measured subsequently at age 24. Adolescents' stories about parent and grandparent socialization in more generative family contexts thus have features that suggest a more compelling process of intergenerational value transmission. 相似文献

A number of recent studies have questioned the conventional view regarding the existence of income-related inequalities in
depression and have suggested that other factors have a more marked impact, most notably those socio-environmental effects
linked to professional status and educational attainment. This paper seeks to measure and decompose the degree of socio-economic
inequality in the factors underlying reported depression by drawing on data from Spain (Spanish National Health Survey, 2003),
a country in which mental care coverage is somewhat limited, but where a marked social transformation has been apparent in
recent decades. Contrary to recent evidence, our findings point towards the existence of significant income-related inequalities
in the prevalence of reported (diagnosed) depression. However, the results from our decomposition analysis are more mixed.
While a modest proportion of overall inequalities (6–13%) is accounted for by income alone, labour status, demographics and
education appear to be more relevant. However, when controlling for potential endogeneity between income and depression by
using instrumental variables (IV), income is found to account for more than 50% of overall inequality in reported depression.
