The purpose of this study was to examine the self-concept and perceived athletic competence of Turkish early adolescents in relation to physical activity level and gender. Self-concept was assessed using the Piers-Harris Children's Self-Concept Scale, and perceived athletic competence was assessed by means of the Athletic Competence subscale of Harter's Self-Perception Profile for Children. In addition, the Weekly Activity Checklist was used for assessing physical activity level. Males and females were assigned to low and high physical activity level groups based on their mean scores. Multivariate analysis of variance revealed significant main effects for gender and physical activity level, but there was no significant gender by physical activity interaction. Univariate analysis demonstrated a significant main effect for physical activity level on perceived athletic competence but not global self-concept. In addition, univariate analysis did not reveal a significant difference in either global self-concept or perceived athletic competence with respect to gender. 相似文献

Both the acquisition and the extinction of memories leave short- and long-term mnemonic traces. Here, we show that in male Wistar rats, the short-term memory for a step-down inhibitory avoidance task (IA) is resistant to extinction, and that its expression does not influence retrieval or extinction of long-term memory. It has been known for some time that short- and long-term inhibitory avoidance memory involve separate and parallel processes. Here we show that, instead, short-term extinction of IA long-term memory is the first step towards its long-term extinction, and that this link requires functional NMDA receptors and protein synthesis in the CA1 region of the dorsal hippocampus at the time of the first CS-no US presentation. 相似文献

Unique temporal change is the key to attentional capture 总被引:2,自引:0,他引:2
Abstract— Attentional capture refers to the observation that some events break through and attract one's attention even when one is engaged in a task for which these events are irrelevant. Previous research, focusing primarily on spatial factors, has shown that a new object is more salient in this regard than an abrupt change in an object's features. Here we show that feature changes can be as effective as new objects in capturing attention, provided that they occur during a period of temporal calm. Conversely, both feature changes and new objects are far less effective in capturing attention when they occur simultaneously with other display changes, such as coincident with the initial onset of the display or with small visual transients that occur during a display transition. These results highlight the importance of considering both space and time in studies of attentional capture; the most effective stimulus is unique in both dimensions. 相似文献

Many memory theorists have assumed that forced-choice recognition tests can rely more on familiarity, whereas item (yes-no)
tests must rely more on recollection. In actuality, several studies have found no differences in the contributions of recollection
and familiarity underlying the two different test formats. Using word frequency to manipulate stimulus characteristics, the
present study demonstrated that the contributions of recollection to item versus forced-choice tests is variable. Low word
frequency resulted in significantly more recollection in an item test than did a forced-choice procedure, but high word frequency
produced the opposite result. These results clearly constrain any uniform claim about the degree to which recollection supports
responding in item versus forced-choice tests. 相似文献

In ‘Freedom and Resentment’ P. F. Strawson argues that reactive attitudes like resentment and indignation cannot be eliminated altogether, because doing so would involve exiting interpersonal relationships altogether. I describe an alternative to resentment: a form of moral sadness about wrongdoing that, I argue, preserves our participation in interpersonal relationships. Substituting this moral sadness for resentment and indignation would amount to a deep and far‐reaching change in the way we relate to each other – while keeping in place the interpersonal relationships, which, Strawson rightfully believes, cannot be eliminated. 相似文献

The prevalence of suicidal ideation/behavior in 1983 or 1987 and its association with future mental health in 2001 were evaluated in a provincially representative sample of Canadian adolescents (n = 1,248) aged 12 to 16 years. Approximately 13.3% (95% CI = 11.5–15.3) of adolescents self‐reported suicidal ideation/behavior. Adolescent agreement with parent (κ = .07) and teacher (κ = .05) reports at baseline was low because adults identified so few subjects. In adulthood, the associations between adolescent self‐reports of suicidal behavior/ideation and major depression and other mental health indicators were explained by respondent sex and adolescent emotional problems reported in 1983/1987. Adolescents with suicidal behavior/ideation often are not recognized by their parents and teachers and may be at risk for persistent psychiatric problems attributable to coexisting mental health problems early‐on. 相似文献
