Adolescent school absenteeism is associated with negative outcomes such as conduct disorders, substance abuse, and dropping out of school. Mental health factors, such as depression and anxiety, have been found to be associated with increased absenteeism from school. Sexual minority youth (youth who are attracted to the same sex or endorse a gay, lesbian, or bisexual identity) are a group at risk for increased absenteeism due to fear, avoidance, and higher rates of depression and anxiety than their heterosexual peers. The present study used longitudinal data to compare sexual minority youth and heterosexual youth on excused and unexcused absences from school and to evaluate differences in the relations between depression and anxiety symptoms and school absences among sexual minority youth and heterosexual youth. A total of 108 14- to 19-years-old adolescents (71% female and 26% sexual minority) completed self-report measures of excused and unexcused absences and depression and anxiety symptoms. Compared to heterosexual youth, sexual minority youth reported more excused and unexcused absences and more depression and anxiety symptoms. Sexual minority status significantly moderated the effects of depression and anxiety symptoms on unexcused absences such that depression and anxiety symptoms were stronger predictors of unexcused absences for sexual minority youth than for heterosexual youth. The results demonstrate that sexual minority status and mental health are important factors to consider when assessing school absenteeism and when developing interventions to prevent or reduce school absenteeism among adolescents. 相似文献

In an essay recently published in this journal (“Is Safety in Danger?”), Fernando Broncano-Berrocal defends the safety condition on knowledge from a counterexample proposed by Tomas Bogardus (Philosophy and Phenomenological Research, 2012). In this paper, we will define the safety condition, briefly explain the proposed counterexample, and outline Broncano-Berrocal’s defense of the safety condition. We will then raise four objections to Broncano-Berrocal’s defense, four implausible implications of his central claim. In the end, we conclude that Broncano-Berrocal’s defense of the safety condition is unsuccessful, and that the safety condition on knowledge should be rejected. 相似文献

The purpose of the current study was to investigate the fit of a bifactor model of the Anxiety Sensitivity Index-3 (ASI-3; Taylor et al. Psychological Assessment, 19, 176–188, 2007) as well as to examine measurement invariance of the ASI-3 across gender. Participants were undergraduate students from the University of Cincinnati (n?=?954; 63 % female). Results indicated that the bifactor model was the best fit to the data, and that this model of AS is fully invariant in terms of gender. The current findings suggest that anxiety sensitivity consists of a general factor and three independent group factors (rather than a higher-order factor with three correlated lower-order factors). The ASI-3 subscales from the bifactor model however did not provide incremental predictive utility above and beyond the general AS factor with respect to an external anxiety criterion. Related research and clinical implications are discussed. 相似文献

The increasing demand for highly automated and flexible tasks capable of assessing visual learning and memory in nonhuman animals has led to the exciting development of a wide array of prefabricated touchscreen-equipped systems. However, the high cost of these prefabricated systems has led many researchers to develop or modify their own preexisting equipment. We developed a freely downloadable App, the Touchscreeen Behavioral Evaluation System (TBES) for use in conjunction with an iPad (Apple, Cupertino, California) as an alternative to prefabricated touchscreen systems. TBES allows for stimulus presentation and data collection on an iPad. The touchscreen technology offered by the iPad is attractive to researchers due to its affordability, reliability, and resistance to false inputs. We highlight these, as well as the feasibility and procedural flexibility of TBES, in an effort to promote our system as a competitive alternative to those currently available. 相似文献

The belief-bias effect is one of the most-studied biases in reasoning. A recent study of the phenomenon using the signal detection theory (SDT) model called into question all theoretical accounts of belief bias by demonstrating that belief-based differences in the ability to discriminate between valid and invalid syllogisms may be an artifact stemming from the use of inappropriate linear measurement models such as analysis of variance (Dube et al., Psychological Review, 117(3), 831–863, 2010). The discrepancy between Dube et al.’s, Psychological Review, 117(3), 831–863 (2010) results and the previous three decades of work, together with former’s methodological criticisms suggests the need to revisit earlier results, this time collecting confidence-rating responses. Using a hierarchical Bayesian meta-analysis, we reanalyzed a corpus of 22 confidence-rating studies (N =?993). The results indicated that extensive replications using confidence-rating data are unnecessary as the observed receiver operating characteristic functions are not systematically asymmetric. These results were subsequently corroborated by a novel experimental design based on SDT’s generalized area theorem. Although the meta-analysis confirms that believability does not influence discriminability unconditionally, it also confirmed previous results that factors such as individual differences mediate the effect. The main point is that data from previous and future studies can be safely analyzed using appropriate hierarchical methods that do not require confidence ratings. More generally, our results set a new standard for analyzing data and evaluating theories in reasoning. Important methodological and theoretical considerations for future work on belief bias and related domains are discussed. 相似文献

The special composition question is the question, ‘When do some things compose something?’ The answers to this question in the literature have largely been at odds with common sense, either by allowing that any two things (no matter how apparently unrelated) compose something, or by denying the existence of most ordinary composite objects. I propose a new ‘series-style’ answer to the special composition question that accords much more closely with common sense, and I defend this answer from van Inwagen's objections. Specifically, I will argue (among other things) that the proposed answer entails the transitivity of parthood, that it is non-circular, and that it casts some light on the ancient puzzle about the Ship of Theseus. 相似文献

The effectiveness of a fixed‐ratio (FR) escalation procedure, developed by Pinkston and Branch (2004) and based on interresponse times (IRTs), was assessed during lever‐press acquisition. Forty‐nine experimentally naïve adult male Long Evans rats were deprived of food for 24 hr prior to an extended acquisition session. Before the start of the session, three food pellets were placed in the magazine. Otherwise, no magazine training, shaping, nor autoshaping procedure was employed. The first 20 presses each resulted in the delivery of a 45‐mg food pellet. Then, the FR increased (2, 4, 8, 11, 16, 20, 25, 30) when each IRT in the ratio was less than 2 s during three consecutive ratios. Sessions lasted 13 hr or until 500 pellets were earned. On average, rats reached a terminal ratio of 11 (mean) or 16 (median) during the first session. Seven rats reached the maximum value of FR 30 and only one rat did not acquire the response. In most rats, a break‐and‐run pattern of responding characteristic of FR schedules began to develop in this acquisition session. Subsequently, the ratio‐escalation procedure continued during daily 2‐hr sessions. In these sessions, the starting ratio requirement was set at the terminal ratio reached in the previous session. Using this procedure, over half (26) of the rats reached the FR 30 requirement by the fourth session. These data demonstrate that a ratio‐escalation procedure based on IRTs provides a time‐efficient way of establishing ratio responding. 相似文献

In 2 experiments, the authors studied the effectiveness of physical and observational practice on learning and the effect on learning of combining physical practice and observation, as compared with providing physical practice alone. In Experiment 1, retention and transfer performance of 30 university students after physical, observational, or no practice were contrasted. Consistent with findings from other studies, the retention results indicated that observational practice is inferior to physical practice. The transfer data indicated no differences between observation and physical practice groups. In Experiment 2, retention and transfer performance of 30 participants in physical and combined (alternating physical and observational) practice groups were contrasted. The retention results showed no differences between the combined and physical practice groups, but the combined group performed significantly better than the physical practice group on the transfer test. Those findings suggest that a combination of observation and physical practice permits unique opportunities for learning beyond those available via either practice regimen alone. 相似文献
