Unemployed adolescents may be at substantial risk of the negative consequences of sexuality. This study investigated the sexual perceptions and practices of 125 unemployed adolescents. Gender, but not age, differences were found in sexual perceptions and practices. Overall, this sample was engaging in high levels of sexual activity with a low rate of condom use.  相似文献

Summary In a recent paper analysing the Simon effect, Hasbroucq and Guiard (1991) concluded that stimulus congruence, a correspondence relationship between stimulus components, accounts for the Simon effect and explains its reversal in the Hedge and Marsh experiment (1975). We contend that their definition of stimulus congruence is applied inconsistently, which invalidates their conclusion. It is argued here that the effect of display-control arrangement correspondence (Simon, Sly, & Vilapakkam, 1981) is an alternative account that fits the presented data better. In a second experiment, Hasbroucq and Guiard (1991) claimed to have invalidated the suggestion that display-control arrangement correspondence could be considered to be an alternative account of the findings in their Experiment 1. However, we assert that the type of display-control arrangement employed in their second experiment was so unpredictable that no effect of display-control arrangement correspondence could occur.  相似文献

This article argues that Weil's interest in occult and esoteric subjects such as Gnosticism and Egyptian mystery religion was not an eccentric sideline to an otherwise ‘Christian’ mysticism but emerged necessarily out of her philosophical method, which, quite independently of those texts where Weil deals with esoterica, displays that pathos of hiddenness so characteristic of occultism: the notion, expressed especially clearly in her late work, that philosophy is the search for a truth hidden from the eyes of ordinary persons and accessible only to those able to endure the ordeals required to gain access into its mysteries. In the second part of the argument, I show that Weil's ‘occultism’ was not an isolated phenomenon but symptomatic of broader trends among intellectuals at the time.  相似文献

A perceived event such as a visual stimulus in the external world and a to-be-produced event such as an intentional action are subserved by event representations. Event representations do not only contain information about present states but also about past and future states. Here we focus on the role of representing future states in event perception and generation (i.e., prospective coding). Relevant theoretical issues and paradigms are discussed. We suggest that the predictive power of the motor system may be exploited for prospective coding not only in producing but also in perceiving events. Predicting is more advantageous than simply reacting. Perceptual prediction allows us to select appropriate responses ahead of the realization of an (anticipated) event and therefore, it is indispensable to flexibly and timely adapt to new situations and thus, successfully interact with our physical and social environment.  相似文献

Generating creative ideas in a brainstorm session `is a crucial part of innovation. However, for actual implementation, the most creative ideas must be selected from a pool of ideas. To date, idea selection has remained relatively unexplored and validated instruments to measure idea selection performance are not systematically employed. This study aimed to improve creative idea selection performance in a field study. In this study, an idea pool of 18 ideas was used, and participants had to select the 5 most creative ideas from the idea pool. Right before participants performed the idea selection task, in the experimental condition, a promotion focus and positive affect was induced in combination with a self-affirmation task. Participants in the control condition performed corresponding filler tasks. The selection of the 5 most creative ideas from the idea pool of 18 ideas was performed individually. Participants in the experimental condition selected ideas that were more creative than did participants in the control condition. These findings provide first evidence that the selection of creative ideas can be enhanced through a combined induction of promotion-focus, positive mood and self-affirmation.  相似文献

The aim of the experiment was to investigate how bi-phasic hitting movements are organized to comply with both impact and temporal precision constraints. 'Bi-phasic' refers to a sequential movement with a preparatory movement away from the interception location followed by a strike phase. The interception location was fixed, as the motion of the hitting device was constrained to follow a straight path orthogonal to that of the approaching balls. We manipulated the required temporal precision by projecting balls with different constant approach speeds (1, 1.5, and 2m/s). Different impact constraints were imposed by instructing participants first to simply hit the ball and subsequently to hit the ball to a designated target area located either 55 or 105 cm away from the interception location. We determined several kinematic variables and used Principal Component Factor Analysis to classify these variables. The analysis revealed two independent factors: a 'velocity' factor (formed by impact velocity, peak velocity of the preparatory phase, peak velocity of the strike phase, and amplitude of the strike) and a 'timing' factor (formed by onset of the preparatory phase, moment of peak velocity of the preparatory phase, and onset of the strike phase). The 'velocity' factor scaled significantly with the required impact constraint and the 'timing' factor scaled significantly with ball speed.  相似文献

The effects of sentence context and grammatical gender on lexical access were investigated in Italian using a timed word-naming paradigm. Large main effects of both sentence context and the gender of the article were observed; the interaction between gender and semantics was significant over subjects. Strong facilitation by both gender and semantics was observed, relative to a neutral-control baseline condition. Results are compared with (1) a prior study with the same design, using a picture-naming paradigm, except that objects described by written words were replaced by pictures (Bentrovato, Devescovi, D'Amico, & Bates, 1999); (2) a separate norming study of timed word reading in a list format, using the same stimuli (D'Amico, Devescovi, & Bates, 2001); and (3) a prior study of German comparing word and picture naming in short, semantically neutral phrases (Jacobsen, 1999). Differences in methodology and in findings between the Italian word naming and the German word naming are compared and discussed. Findings of the present study are interpreted in support of interactive-activation models in which different sources of information are combined on-line to predict, anticipate, or preactivate lexical targets.  相似文献

Understanding the dropout rates of efficacious forms of psychotherapy for patients with binge eating disorder (BED) is an unsolved problem within this increasing population. Up until now the role of psychotherapy process characteristics as predictors of premature termination has not been investigated in the BED literature. Within a randomized controlled trial (N=78) we investigated the degree to which early psychological process characteristics, such as components of the therapeutic relationship and the experiences of mastery and motivational clarification, predicted premature termination of treatment. We statistically controlled for the influences of covariates such as rapid response of treatment, treatment group, body mass index, Axis II disorder, and patients' preexisting generalized self-efficacy at baseline. Patients' postsession reports from Sessions 1 to 5 indicated that low self-esteem in-session experiences was a stable predictor of premature termination. Its predictive value persisted after controlling for the above-mentioned covariates. Exploratory analyses further revealed low self-esteem experiences, low global alliance, and low mastery and clarification experiences as predictors in those patients who explicitly specified discontentment with therapy as reason for premature termination. These results indicate that patients' self-esteem experiences may not be an epiphenomenon of their specific psychopathology but may represent general mechanisms on which remaining or withdrawing from psychotherapeutic treatment depends. Early psychotherapy process characteristics should therefore be considered in training and evaluation of psychotherapists carrying through BED treatments.  相似文献

Although many interventions address children’s externalizing behavior problems, negative treatment outcomes remain common. Reasons for success or failure are frequently unclear, due in part to a lack of research identifying treatment change mechanisms. The current study evaluated differential attention as a mechanism of change in Parent–Child Interaction Therapy (PCIT), a treatment for children with externalizing problems. Using sequential coding and time-series analysis, we examined parent–child interactions across treatment for three families. Contrary to hypotheses, child prosocial behaviors and parent skill use held steady or decreased across coaching periods, with the exception of one family, where the parent’s skill use increased during coaching. Partial support was found for the hypothesis that parent differential attention would predict child prosocial behavior in the next minute. These results provide support for differential attention as a mechanism of change, but also demonstrate that this factor is not the only such mechanism.  相似文献
