Two studies with college student participants (n's=262, 239) examined the relation between perceptions of threat (i.e., perceptions of the probabilities and costs of future undesirable outcomes) and: (a) worry; and (b) hypothesized antecedents of perceived threat. In both studies, higher levels of worrying were associated with higher perceived probability and cost. In Study 2, the association between perceived threat and worrying remained even when taking into account maladaptive worry beliefs and the desire for predictability; in fact, the relation between worrying and worry beliefs and desire for predictability were moderated by perceptions of threat. Higher levels of perceived probability were associated with perceiving oneself and others less favorably, whereas higher levels of perceived cost were associated with higher standards.  相似文献

The authors investigated the idea that memory systems might have evolved to help us remember fitness-relevant information--specifically, information relevant to survival. In 4 incidental learning experiments, people were asked to rate common nouns for their survival relevance (e.g., in securing food, water, or protection from predators); in control conditions, the same words were rated for pleasantness, relevance to moving to a foreign land, or personal relevance. In surprise retention tests, participants consistently showed the best memory when words were rated for survival; the survival advantage held across recall, recognition, and for both within-subject and between-subjects designs. These findings suggest that memory systems are "tuned" to remember information that is processed for fitness, perhaps as a result of survival advantages accrued in the past.  相似文献

Using vision, humans can accurately judge distances to locations on the ground surface up to distances of at least 20 m. Most theories of depth perception assume that this ability is associated with the fact that we live in a terrestrial world in which locations of interest often appear on the ground and for which feedback about distance is often available from nonvisual sources such as walking. Much less is known about the ability of humans to judge absolute distances to locations other than on or supported by the ground plane beyond a few meters, at which point binocular stereo provides at best limited information about distance scaling. We show that one commonly used action measure for probing absolute distance perception exhibits accurate performance, even for targets located on the ceiling of a large room. We follow this with evidence that distance to ceiling locations is recovered with a mechanism that depends, at least in part, on the angle from the line of sight to the target location and a gravity-based frame of reference.  相似文献

We examined the effects of retention intervals on the recollection of the emotional content of events. Memory for personal events was tested for three retention intervals: 3 months, 1 year, and 4.5 years. Participants made pleasantness ratings both at the time of recording the event and during testing of the events. Analyses of the data show that judgments of pleasantness or unpleasantness of an event became less extreme as retention interval increased. This effect was larger for unpleasant events than for pleasant events. Subsequent memory ratings of pleasant and unpleasant events showed a modest effect of pleasantness with pleasant events remembered slightly better than unpleasant events. The theoretical implications of these data are discussed. © 1997 John Wiley & Sons, Ltd.  相似文献

Strain or problem-solving models posit that deviance persists because it enhances youths' psychosocial properties and is therefore functional for adolescents. However, empirical tests of this assumption have been limited to determining whether a moderately social activity like delinquency produces time-ordered changes in self-esteem. This research examines whether a highly social activity like alcohol use improves adolescents' relations with peers and self-esteem over time. The results of a four-year panel study show that the effects of early alcohol use are limited to enhancing peer relations only among adolescents who use alcohol in order to be part of the group. Early alcohol consumption also has a delayed effect on boosting self-esteem, but this effect is restricted to youths who equate drinking with sophistication. The lack of generality of these findings and how the psychological functions of drinking might cancel these effects are discussed.  相似文献

Pathological tongue thrust (reverse swallowing) has been associated with neuromuscular disorders and linked to dental malocclusion, articulation problems, difficulty in eating, and excessive drooling. In this study, observable tongue thrust in a 10-year-old retarded male was modified during mealtime using a procedure consisting of differential reinforcement (presentation of food contingent upon tongue in) and punishment (gently pushing the tongue back into the mouth with a spoon). Results of a reversal design showed substantial decreases in tongue thrust and food expulsion, and a large increase in observed chewing. These data compared favorably with data obtained for other retarded persons not judged to be tongue thrusters; in addition, the objective results of the treatment program were substantiated via pre-post evaluations done by occupational and physical therapists. These findings suggest that operant techniques may be an effective means of treating tongue thrust and its associated problems, and that further development and evaluation of behavioral interventions may provide a desirable alternative to more intrusive surgical or mechanical procedures.  相似文献

We investigated the relationship between gender and clinician diagnosis of a depressive disorder at intake on variables reflecting depression among adolescents in residential treatment. It was hypothesized that females diagnosed with a depressive disorder would have the highest scores on measures of suicide risk, the number of symptoms of a major depressive episode, suicidal behavior, and suicidal ideation. Results indicated partial support for the predicted comparisons. Females diagnosed with a depressive disorder scored significantly higher on measures of depressive symptom count and suicidal ideation. Surprisingly, females without a diagnosis of a depressive disorder had higher suicide risk scores than the remaining groups. The results of this study highlight the importance of assessment and treatment of internalizing disorders in youth entering residential programs, particularly female adolescents.  相似文献

If two subjects have phenomenally identical experiences, there is an important sense in which the way the world appears to them is precisely the same. But how are we to understand this notion of ‘ways of appearing’? Most philosophers who have acknowledged the existence of phenomenal content have held that the way something appears is simply a matter of the properties something appears to have. On this view, the way something appears is simply the way something appears to be. This identification supports a Russellian theory of phenomenal content, according to which phenomenal content is exhausted by facts about what specific properties are represented by an experience. The present paper motivates and develops an alternative Fregean theory of phenomenal colour content. According to Fregean theories, the phenomenal content that is shared by any two phenomenally identical experiences is a matter of how the world is represented, and need not involve sameness in what is represented. It is argued that ways of appearing are modes of presentations of external properties and objects, and a detailed theory is presented about the nature of the modes of presentation involved in colour experience.  相似文献

A meta-analysis was conducted to determine the relationship between appearance and weight-based teasing and three outcome measures: body dissatisfaction, restrictive eating, and bulimic behaviors. Four meta-analyses were conducted. Fifty effect sizes (N = 10,618) resulted in a moderate effect size of .39 for the relationship between weight teasing and body dissatisfaction; 24 effect sizes (N = 7190) resulted in an effect size of .32 for the relationship between appearance teasing and body dissatisfaction; 20 effect sizes (N = 4792) resulted in an effect size of .35 for the relationship between weight teasing and dietary restraint; and 22 effect sizes (N = 5091) resulted in an effect size of .36 for the relationship between weight teasing and bulimic behaviors. Significant moderators that emerged were teasing measure type, publication type, study type, age group, and gender. The findings offer further support for the inclusion of strategies in body image and eating disorders’ prevention and intervention programs that focus on handling negative, appearance-related commentary.  相似文献
