Selection of high vs low valued letters from a briefly presented visual array was investigated. An indicator specifying the value of letters occurred before or after the array. Selection could occur during input to memory or during output from memory in the before condition, but only at output in the after condition. Previous research using an alphabetic instruction, which required letter identification prior to selection, attributed selection to output. A color instruction in the -present experiment, not requiring letter identification, showed the locus of selection to be at input. Experiment 2 replicated these findings and used an interference technique to add further support. In addition, contrary to previous findings, these results indicated that the selection process caused no deficit in overall recall. 相似文献

Patterns of agreement between parent and child ratings of psychosocial functioning and fatigue in children with obesity were examined. Analyses demonstrated moderate agreement for social anxiety in elementary children and small agreement for social anxiety in adolescents. Results of analyses of overall quality of life revealed small agreement in children under the age of 8, large agreement in children ages 8–12, and moderate agreement in adolescents ages 13–18. Overall ratings of fatigue demonstrated moderate agreement both in elementary children and in adolescents. A meaningful relationship was found between each factor measured by a parent and a child. Patterns which were unexpected given the existing literature were found; possible hypotheses explaining these patterns are presented; and the need for further research is highlighted. 相似文献

Using thematic analysis of interview data, the present study assessed teen girls’ and young adult women’s attitudes toward posting sexualized profile photos on Facebook. In addition, sexualization behaviors depicted in participants’ profile photos were examined. Participants overwhelmingly disapproved (either in a reluctant or a clear manner) of posting a profile photo of oneself in underwear on social media. A somewhat different pattern emerged in attitudes about posting a swimsuit photo in which specific conditions were laid out determining whether swimsuit photos were acceptable or not. Sexualization cues in profile photos were generally low. Findings suggest that posting a sexualized photo on social media comes with relational costs for girls and women. Strategies for educating young people about new media use and sexualization are discussed. 相似文献

Individuals with autism spectrum disorder (ASD) often exhibit noncompliance during medical exams. One intervention used to address this concern is differential reinforcement. Although differential reinforcement includes extinction, it may not be feasible or safe to implement extinction during medical exams. In the current study, we evaluated differential reinforcement without extinction and differential reinforcement without extinction plus stimulus fading, for increasing compliance during routine medical exams exhibited by 4 individuals with ASD. An indirect assessment identified problematic medical procedures, and a functional analysis showed that participants' disruptive behavior was maintained by escape from medical tasks. Differential reinforcement without extinction was insufficient in increasing medical compliance with 3 of 4 participants. The addition of a modified stimulus fading procedure that involved gradually introducing smaller components of problematic exam steps was effective in increasing medical compliance with all exam steps. 相似文献

ABSTRACT We examined personality predictors of different attitude strength-related dimensions across objects. Participants responded to questions regarding 11 attitude objects that assessed the overall evaluation of the object and the strength-related dimensions of importance, certainty, and relevance. Confirmatory factor analyses supported a 4-factor solution underlying the self-report and extremity dimensions across the 11 attitude objects, with importance and relevance and certainty and extremity loading on 2 second-order factors. The need to evaluate, need for affect, sense of coherence, dogmatism, and personal fear of invalidity were all related at the bivariate level to at least one strength-related dimension. The need to evaluate and the need for affect independently predicted variance in certainty/extremity across the attitude objects and sense of coherence and dogmatism predicted unique variance in importance/relevance across objects. Discussion focuses on the possible processes by which personality variables predict strength-related dimensions across objects. 相似文献

Utility of a CPT in diagnosing ADHD among a representative sample of high-risk children: a cautionary study. 总被引:1,自引:0,他引:1
Continuous performance tests (CPTs) are widely used in the assessment and study of attention deficit hyperactivity disorder (ADHD). Although CPTs have reliably found differences between children with ADHD and normal controls, discriminating between children with ADHD and children with subclinical levels of behavioral or cognitive problems is a more clinically relevant and difficult endeavor. Additionally, most studies use convenience samples from clinical care settings that may not represent the ADHD population as a whole. The current study assessed the utility of a clinically used CPT, the Test of Variables of Attention (TOVA), in distinguishing between children with ADHD and children with subclinical levels of attention/behavior problems. Participants constituted a representative sample of elementary school students at high risk for ADHD, including 116 children with ADHD and 51 subclinical controls. Results found no significant differences between the ADHD and subclinical group on CPT variables, and CPT performance did not reliably predict group membership. Implications of the findings are discussed. 相似文献

This article describes how to collect responses from experimental participants using drag and drop on a Web page. In particular, we describe how drag and drop can be used in a text search task in which participants read a text and then locate and categorize certain elements of the text (e.g., to identify the main claim of a persuasive paragraph). Using this technique, participants respond by clicking on a text segment and dragging it to a screen field or icon. We have successfully used this technique in both the argument element identification experiment that we describe here and a tutoring system that we created to teach students to identify source characteristics while reading historical texts (Britt, Perfetti, Van Dyke, & Gabrys, 2000). The implementation described here exploits the capability of recent versions of Microsoft's Internet Explorer Web browser to handle embedded XML documents and drag and drop events. 相似文献

When a location is cued, targets appearing at that location are detected more quickly. When a target feature is cued, targets bearing that feature are detected more quickly. These attentional cueing effects are only superficially similar. More detailed analyses find distinct temporal and accuracy profiles for the two different types of cues. This pattern parallels work with probability manipulations, where both feature and spatial probability are known to affect detection accuracy and reaction times. However, little has been done by way of comparing these effects. Are probability manipulations on space and features distinct? In a series of five experiments, we systematically varied spatial probability and feature probability along two dimensions (orientation or color). In addition, we decomposed response times into initiation and movement components. Targets appearing at the probable location were reported more quickly and more accurately regardless of whether the report was based on orientation or color. On the other hand, when either color probability or orientation probability was manipulated, response time and accuracy improvements were specific for that probable feature dimension. Decomposition of the response time benefits demonstrated that spatial probability only affected initiation times, whereas manipulations of feature probability affected both initiation and movement times. As detection was made more difficult, the two effects further diverged, with spatial probability disproportionally affecting initiation times and feature probability disproportionately affecting accuracy. In conclusion, all manipulations of probability, whether spatial or featural, affect detection. However, only feature probability affects perceptual precision, and precision effects are specific to the probable attribute. 相似文献

Given the accumulating evidence for a role of anxiety sensitivity in the etiology of panic, it is important to understand the developmental origins of anxiety sensitivity. To this end, this study examined the relation between attachment beliefs and anxiety sensitivity in a sample of high school students (n = 203; mean age 15.7 years) and university students (n = 324; mean age 21.7 years). The Experiences in Close Relationships (ECR; K. Brennan, C. Clark, &; P. Shaver, 1998) was used to assess attachment beliefs and to classify participants into attachment groups. The Anxiety Sensitivity Index (ASI; R. A. Peterson &; S. Reiss, 1987) was used to assess participants' levels of anxiety sensitivity. Results supported the hypothesis that individuals with insecure attachment, specifically those classified as preoccupied and fearful (i.e., those with a negative model of self), had significantly higher anxiety sensitivity scores than securely attached individuals in both the high school and college samples. 相似文献
