Recent research has begun to investigate the impact of different formats for rational numbers on the processes by which people make relational judgments about quantitative relations. DeWolf, Bassok, and Holyoak (Journal of Experimental Psychology: General, 144(1), 127–150, 2015) found that accuracy on a relation identification task was highest when fractions were presented with countable sets, whereas accuracy was relatively low for all conditions where decimals were presented. However, it is unclear what processing strategies underlie these disparities in accuracy. We report an experiment that used eye-tracking methods to externalize the strategies that are evoked by different types of rational numbers for different types of quantities (discrete vs. continuous). Results showed that eye-movement behavior during the task was jointly determined by image and number format. Discrete images elicited a counting strategy for both fractions and decimals, but this strategy led to higher accuracy only for fractions. Continuous images encouraged magnitude estimation and comparison, but to a greater degree for decimals than fractions. This strategy led to decreased accuracy for both number formats. By analyzing participants’ eye movements when they viewed a relational context and made decisions, we were able to obtain an externalized representation of the strategic choices evoked by different ontological types of entities and different types of rational numbers. Our findings using eye-tracking measures enable us to go beyond previous studies based on accuracy data alone, demonstrating that quantitative properties of images and the different formats for rational numbers jointly influence strategies that generate eye-movement behavior.  相似文献

Despite frequent informal or anecdotal acknowledgement of the usefulness of neuropsychological services within various settings, including mental health settings, few studies have formally investigated the satisfaction, perceived utility, or outcomes associated with such a service. This survey‐based study evaluated referring clinicians’ (n = 35) perceptions of the usefulness and outcomes associated with the provision of clinical neuropsychological assessment and feedback within an adolescent and young adult public mental health service in Melbourne, Australia. The results suggest that referrers perceive the neuropsychological service, including formal neuropsychological assessment report and verbal and written feedbacks, as a highly useful adjunct to their clinical practice. In addition, referrers frequently reported clinically meaningful outcomes in association with the neuropsychological service, including diagnostic changes or additions (11% of clients referred), changes to approaches in treatment (52% of clients referred), and increased or appropriate access to services, education, or work (33% of clients referred). Referrers also reported that almost 60% of neuropsychological assessment reports were forwarded to other services or clinicians involved in the client's care. The findings suggest that mental health settings are likely to benefit from routine inclusion of specialist neuropsychology services. However, future research should also examine client and family perceptions regarding the satisfaction and usefulness of neuropsychological services.  相似文献

Diminished positive experiences and events might be part of the phenomenology of social anxiety; however, much of this research is cross-sectional by design, limiting our understanding of the everyday lives of socially anxious people. Sexuality is a primary source of positive experiences. We theorized that people with elevated social anxiety would have relatively less satisfying sexual experiences compared to those who were not anxious. For 21 days, 150 college students described their daily sexual episodes. Social anxiety was negatively related to the pleasure and feelings of connectedness experienced when sexually intimate. The relationship between social anxiety and the amount of sexual contact differed between men and women—it was negative for women and negligible for men. Being in a close, intimate relationship enhanced the feelings of connectedness during sexual episodes for only individuals low in social anxiety. Depressive symptoms were negatively related to the amount of sexual contact, and the pleasure and feelings of connectedness experienced when sexually intimate. Controlling for depressive symptoms did not meaningfully change the social anxiety effects on daily sexuality. Our findings suggest that fulfilling sexual activity is often compromised by social anxiety.  相似文献

Long hours of paid employment during high school have been linked to a variety of problem behaviors, but questions remain about whether and to what extent work intensity makes any causal contribution. This study addresses those questions by focusing on how 12th-grade work intensity is associated with substance use and educational attainment in the years following high school. It uses 2 nationally representative longitudinal data sets from the Monitoring the Future project, spanning a total of 3 decades. One data set tracks 8th graders for 8 years (modal ages 14-22) and provides extensive controls for possible prior causes; the second, larger data set tracks 12th graders for up to 12 years (to modal ages 29-30) and permits assessment of possible short-term and longer term consequences. Findings based on propensity score matching and multivariate regression analyses are highly consistent across the 2 sets of data. All findings show that more fundamental prior problems, including low academic performance and aspirations, make substantial contributions to substance use and long-term academic attainment (selection effects), but the findings also suggest that high work intensity during high school has long-term costs in terms of college completion and perhaps cigarette use.  相似文献

Prior research has demonstrated deficits in defensive reactivity (indexed by potentiation of the startle blink reflex) in psychopathic individuals. However, the basis of this association remains unclear, as diagnostic criteria for psychopathy encompass two distinct phenotypic components that may reflect differing neurobiological mechanisms-an affective-interpersonal component and an antisocial deviance component. Likewise, the role of defensive response deficits in antisocial personality disorder (APD), a related but distinct syndrome, remains to be clarified. In the current study, the authors examined affective priming deficits in relation to factors of psychopathy and symptoms of APD using startle reflex methods in 108 adult male prisoners. Deficits in blink reflex potentiation during aversive picture viewing were found in relation to the affective-interpersonal (Factor 1) component of psychopathy, and to a lesser extent in relation to the antisocial deviance (Factor 2) component of psychopathy and symptoms of APD-but only as a function of their overlap with affective-interpersonal features of psychopathy. These findings provide clear evidence that deficits in defensive reactivity are linked specifically to the affective-interpersonal features of psychopathy and not to the antisocial deviance features represented most strongly in APD.  相似文献

This study systematically replicated and extended previous research on response interruption and redirection (RIRD) by assessing instructed responses of a different topography than the target behavior, percentage of session spent in treatment, generalization of behavior reduction, and social validity of the intervention. Results showed that RIRD produced substantial decreases in vocal stereotypy. Limitations of this study were that behavior reduction did not generalize to novel settings or with novel instructors and that appropriate vocalizations did not improve.  相似文献

Curious people seek knowledge and new experiences. In 3 studies, we examined whether, when, and how curiosity contributes to positive social outcomes between unacquainted strangers. Study 1 (98 college students) showed that curious people expect to generate closeness during intimate conversations but not during small talk; less curious people anticipated poor outcomes in both situations. We hypothesized that curious people underestimate their ability to bond with unacquainted strangers during mundane conversations. Studies 2 (90 college students) and 3 (106 college students) showed that curious people felt close to partners during intimate and small-talk conversations; less curious people only felt close when the situation offered relationship-building exercises. Surprise at the pleasure felt during this novel, uncertain situation partially mediated the benefits linked to curiosity. We found evidence of slight asymmetry between self and partner reactions. Results could not be attributed to physical attraction or positive affect. Collectively, results suggest that positive social interactions benefit from an open and curious mind-set.  相似文献

This study explores the effects of disclosing a history of childhood sexual abuse on empathy for Roman Catholic priests. The research design randomly selected priests in good standing in the Roman Catholic Church from 10 locations in the United States. Three groups of priests were identified based on self-report: (a) priests who report sexual abuse and no disclosure, (b) priests who report sexual abuse and disclosure, and (c) priests who report no sexual abuse. The three groups were compared using the Interpersonal Reactivity Index dimensions of perspective-taking, empathic concern, and personal distress as the dependent variable. The data was analyzed using hierarchical multiple regression to examine the incremental contributions for the different sets of independent variables. Results indicate that empathy was not exclusively associated with disclosing sexual abuse. The need for earlier intervention, education, and assistance for priests in disclosing childhood sexual abuse is discussed.  相似文献
