引入眼动注视点的联合-交叉负载多模态认知诊断建模

多模态数据为实现对认知结构的精准诊断及其他认知特征(如, 认知风格)的全面反馈提供了可能性。为实现对题目作答精度、作答时间(RT)和视觉注视点数(FC)的联合分析, 本文基于联合-交叉负载建模法提出3个多模态认知诊断模型。实证研究及模拟研究结果表明: (1)联合分析比分离分析更适用于多模态数据; (2)新模型可直接利用RT和FC中信息提高潜在能力或潜在属性的估计准确性; (3)新模型的参数估计返真性较好; (4)忽略交叉负载所导致的负面结果比冗余考虑交叉负载所导致的更严重。     

整合对联结再认和项目再认的促进作用：“只有收益”观点

研究旨在探讨整合如何影响联结再认和项目再认及其加工过程。编码阶段要求被试学习复合词和非复合词, 提取阶段完成联结再认和项目再认测验。结果显示, 复合词比非复合词有更好的联结再认表现, 但在项目再认表现上两者之间没有显著的差异。ERP结果显示, 在联结再认上, 复合词诱发显著的FN400效应(与熟悉性加工有关)和LPC效应(与回想加工有关), 非复合词只诱发显著的LPC效应, 且复合词比非复合词有更大的LPC效应。在项目再认上, 复合词比非复合词诱发更大的FN400效应。总而言之, 整合在促进联结再认的同时并不会损害项目再认的表现, 支持了“只有收益”观点。     

Disruptive effects of contingent food on high-probability behavior

The delivery of food contingent on 10 s of consecutive toy engagement resulted in a decrease in engagement and a corresponding increase in other responses that had been previously reinforced with food. Similar effects were not observed when tokens exchangeable for the same food were delivered, suggesting that engagement was disrupted by the contingent provision of the food, which may have functioned as a discriminative stimulus that occasioned competing responses.     

Group status is related to group prototypicality in the absence of social identity concerns

Based on self-categorization theory, group status should be positively related to group prototypicality when the relevant superordinate category is positively valued. In this case, high-status groups should be perceived to be more prototypical than low-status groups even in the absence of concerns about maintaining a positive social identity. To test this hypothesis, a minimal group study was conducted in which participants (N = 139) did not belong to any of the groups involved. Consistent with predictions, participants perceived high-status groups to be significantly more prototypical than low-status groups. Consistent with self-categorization theory's cognitive analysis, these results demonstrate that the relation between group status and group prototypicality is a relatively basic and pervasive effect that does not depend on social identity motives.     

Response strength in extreme multiple schedules

Four pigeons were trained in a series of two-component multiple schedules. Reinforcers were scheduled with random-interval schedules. The ratio of arranged reinforcer rates in the two components was varied over 4 log units, a much wider range than previously studied. When performance appeared stable, prefeeding tests were conducted to assess resistance to change. Contrary to the generalized matching law, logarithms of response ratios in the two components were not a linear function of log reinforcer ratios, implying a failure of parameter invariance. Over a 2 log unit range, the function appeared linear and indicated undermatching, but in conditions with more extreme reinforcer ratios, approximate matching was observed. A model suggested by McLean (1991), originally for local contrast, predicts these changes in sensitivity to reinforcer ratios somewhat better than models by Herrnstein (1970) and by Williams and Wixted (1986). Prefeeding tests of resistance to change were conducted at each reinforcer ratio, and relative resistance to change was also a nonlinear function of log reinforcer ratios, again contrary to conclusions from previous work. Instead, the function suggests that resistance to change in a component may be determined partly by the rate of reinforcement and partly by the ratio of reinforcers to responses.     

Assessing the Robustness of Mixture Models to Measurement Noninvariance

Abstract

Recent work reframes direct effects of covariates on items in mixture models as differential item functioning (DIF) and shows that, when present in the data but omitted from the fitted latent class model, DIF can lead to overextraction of classes. However, less is known about the effects of DIF on model performance—including parameter bias, classification accuracy, and distortion of class-specific response profiles—once the correct number of classes is chosen. First, we replicate and extend prior findings relating DIF to class enumeration using a comprehensive simulation study. In a second simulation study using the same parameters, we show that, while the performance of LCA is robust to the misspecification of DIF effects, it is degraded when DIF is omitted entirely. Moreover, the robustness of LCA to omitted DIF differs widely based on the degree of class separation. Finally, simulation results are contextualized by an empirical example.     

Ready, Willing, and Able: Developing a Support System to Promote Implementation of School-Based Prevention Programs

While the number and scope of evidence‐based health, education, and mental health services continues to grow, the movement of these practices into schools and other practice settings remains a complex and haphazard process. The purpose of this paper is to describe and present initial support for a prevention support system designed to promote high‐quality implementation of whole school prevention initiatives in elementary and middle schools. The function and strategies of a school‐based prevention support system are discussed, including key structures and activities undertaken to identify, select, and provide technical assistance to school personnel. Data collected over a 5 year period are presented, including evidence of successful implementation support for 5 different evidence‐based programs implemented with fidelity at 12 schools and preliminary evidence of goal attainment. Findings suggest the ongoing collection of information related to organizational readiness assists in the adoption and implementation of effective practices and initiatives and provide valuable insight into the development of results‐oriented approaches to prevention service delivery. Problems, progress, and lessons learned through this process are discussed to frame future research and action steps for this school‐based prevention support system.

“Hit Me, Maybe, One More Time”: Brief measures of impulsivity and sensation seeking and their prediction of blackjack bets and sexual promiscuity

We sought to construct an efficient, reliable, and valid self-report measure of impulsivity and sensation-seeking. We used item response theory to identify the 8 best items (ImpSS-8) from the 19-item Impulsivity and Sensation-Seeking Scale (Zuckerman, Kuhlman, Joireman, Teta, & Kraft, 1993; Study 1). The ImpSS-8 interacted with a manipulated ego threat to predict blackjack bets: in a weak situation (no ego threat), individual differences were strong (a positive ImpSS-8-bets relationship); in a strong situation (ego threat), individual differences were weak (no relationship; Study 2). The ImpSS-8’s 4-item impulsivity and sensation-seeking subscales related differentially to the Balloon Analogue Risk Task (Study 2) as well as trait measures of openness and conscientiousness, hostility and physical aggression, and sexually promiscuous attitudes and timing (Study 3).     

Reconsidering the ‘heresy’ of using treatment manuals

Some argue that the medical model and the experimental design that underlies the use of treatment manuals to prove the efficacy of a psychotherapeutic treatment clashes with the theoretical basis of family therapy. From the point of view of the empirically supported treatments (ESTs) movement, treatment manuals are the operationalization of the independent variable in a clinical trial; the therapist is only part of the procedure and the therapeutic relationship is a confounding variable. Applying that logic to the practice of family therapy might be considered a heresy. This article argues that paradoxically, this heresy has a lot to offer the practice of family therapy. Research is the best way to answer questions like ‘how does family therapy work?’ ‘What makes ‘good therapy’ good?’ ‘Do therapists do what they say they do'? This article recommends an alternative framework for integrating ESTs into practice by proposing empirically informed guides to practice which, being less formulaic, encourage process‐outcome research, are coherent with the systemic model and do not constrain the therapist's creativity. Such guidelines allow therapists to use manuals flexibly so that they deepen the understanding of the process of therapy. We encourage you to listen to the JFT Editor, Mark Rivett, as he interviews the author on Manuals in the Practice and Research of Family Therapy.

Reflection and reasoning in moral judgment

While there is much evidence for the influence of automatic emotional responses on moral judgment, the roles of reflection and reasoning remain uncertain. In Experiment 1, we induced subjects to be more reflective by completing the Cognitive Reflection Test (CRT) prior to responding to moral dilemmas. This manipulation increased utilitarian responding, as individuals who reflected more on the CRT made more utilitarian judgments. A follow-up study suggested that trait reflectiveness is also associated with increased utilitarian judgment. In Experiment 2, subjects considered a scenario involving incest between consenting adult siblings, a scenario known for eliciting emotionally driven condemnation that resists reasoned persuasion. Here, we manipulated two factors related to moral reasoning: argument strength and deliberation time. These factors interacted in a manner consistent with moral reasoning: A strong argument defending the incestuous behavior was more persuasive than a weak argument, but only when increased deliberation time encouraged subjects to reflect.
