Empathy as a buffer: How empathy moderates the emotional effects on Preschoolers’ sharing

This study experimentally investigated how empathy moderated the influence of external emotional stimuli on preschoolers’ subsequent sharing behaviour. Children aged 4–6 (N = 218) were randomly presented with one of the video clips that elicited sad, happy, or neutral emotion, and were then asked to play a dictator game with puppet partners. Results revealed that compared to the neutral condition, children with higher empathy increased sharing after induced happiness but did not change sharing after induced sadness; by contrast, children with lower empathy decreased sharing after induced sadness. It appears that empathy may enhance the positive effect of happiness while reducing the negative effect of sadness on sharing behaviour. These findings provide experimental evidence in early childhood to support approaches that emphasize the role of immediate emotions in moral decision-making; critically, such emotional effects vary with individual differences in dispositional empathy.     

From teachers’ implicit theories of intelligence to job stress: The mediating role of teachers’ causal attribution of students’ academic achievement

To better understand the cognitive antecedents of teachers’ stress in the school setting, the effects of teachers’ beliefs regarding intelligence and their causal attributions of students’ academic performance on teachers’ job stress were examined in the current study. We recruited 271 teachers who voluntarily filled out an anonymous questionnaire. Findings demonstrated that teachers who endorsed the entity theory of intelligence tended to attribute students’ poor performance to students’ inability but not lack of effort. Results showed a positive relationship between teachers’ fixed view of intelligence and job stress, and this relationship was mediated by teachers’ attributing students’ poor performance to students’ lack of ability, even after controlling for teacher efficacy. We suggest to promote the psychological health of teachers by incorporating intelligence mindset and attribution training programs in preservice teacher education, professional development, and cognitive behavioral stress intervention for in-service teachers.     

Inserting mastered targets during error correction when teaching skills to children with autism

Research has identified a variety of effective approaches for responding to errors during discrete‐trial training. In one commonly used method, the therapist delivers a prompt contingent on the occurrence of an incorrect response and then re‐presents the trial so that the learner has an opportunity to perform the correct response independently. Some authors recommend inserting trials with previously mastered targets between the prompted response and opportunities to respond independently, but no studies have directly examined the benefits of this approach. In this study, we manipulated the placement of trials with mastered targets during discrete‐trial training to compare the effectiveness of error correction with and without this recommended insertion procedure. Four children with autism participated, and each was taught 18 targets across 3 target sets. Results indicated that embedding trials with mastered targets into error correction may not confer benefits for most children and that doing so may lead to less efficient instruction.     

Depletion from Self‐Regulation: A Resource‐based Account of the Effect of Value Incongruence

Value incongruence between employees and organizations has been identified as a negative work condition. An attitude‐based account suggests that value incongruence gives rise to negative attitudes toward organizations and thus causes low performance. To complement this mechanism, we propose a resource‐based account based on ego‐depletion theory, which suggests that value incongruence consumes an individual's regulatory resources and leads to low work performance. In support of this view, results from 2 survey studies and a vignette experiment reveal that value incongruence is positively associated with ego depletion, which in turn is negatively related to work performance. The mediation effect of ego depletion is independent of the attitude‐based mechanism as represented by job satisfaction and affective commitment. Consistent with the affective consistency perspective, the relationship between value incongruence and ego depletion is stronger among employees high in positive affectivity and weaker among employees high in negative affectivity. The corresponding moderated mediation analysis shows that the indirect effects of value incongruence on work performance through ego depletion vary as a function of positive and negative affectivity. This investigation unravels the self‐regulatory consequence of value incongruence and shows that the resource‐based mechanism of value incongruence operates differentially as a function of dispositional affectivity.     

The Invisible Hand: Toddlers Connect Probabilistic Events With Agentive Causes

Children posit unobserved causes when events appear to occur spontaneously (e.g., Gelman & Gottfried, 1996). What about when events appear to occur probabilistically? Here toddlers (M = 20.1 months) saw arbitrary causal relationships (Cause A generated Effect A; Cause B generated Effect B) in a fixed, alternating order. The relationships were then changed in one of two ways. In the Deterministic condition, the event order changed (Event B preceded Event A); in the Probabilistic condition, the causal relationships changed (Cause A generated Effect B; Cause B generated Effect A). As intended, toddlers looked equally long at both changes (Experiment 1). We then introduced a previously unseen candidate cause. Toddlers looked longer at the appearance of a hand (Experiment 2) and novel agent (Experiment 3) in the Deterministic than the Probabilistic conditions, but looked equally long at novel non‐agents (Experiment 4), suggesting that by 2 years of age, toddlers connect probabilistic events with unobserved agents.     

Fitting the Reduced RUM with Mplus: A Tutorial

The Reduced Reparameterized Unified Model (Reduced RUM) is a diagnostic classification model for educational assessment that has received considerable attention among psychometricians. However, the computational options for researchers and practitioners who wish to use the Reduced RUM in their work, but do not feel comfortable writing their own code, are still rather limited. One option is to use a commercial software package that offers an implementation of the expectation maximization (EM) algorithm for fitting (constrained) latent class models like Latent GOLD or Mplus. But using a latent class analysis routine as a vehicle for fitting the Reduced RUM requires that it be re-expressed as a logit model, with constraints imposed on the parameters of the logistic function. This tutorial demonstrates how to implement marginal maximum likelihood estimation using the EM algorithm in Mplus for fitting the Reduced RUM.

Perceptual simulation in conceptual combination: Evidence from property generation

In three experiments, participants received nouns or noun phrases for objects and verbally generated their properties (“feature listing”). Several sources of evidence indicated that participants constructed perceptual simulations to generate properties for the noun phrases during conceptual combination. First, the production of object properties for noun phrases depended on occlusion, with unoccluded properties being generated more often than occluded properties. Because a perceptual variable affected conceptual combination, perceptual simulations appeared central to combining the concepts for modifiers and head nouns. Second, neutral participants produced the same distributions of properties as participants instructed to describe images, suggesting that the conceptual representations used by neutral participants were similar to the mental images used by imagery participants. Furthermore, the property distributions for neutral and imagery participants differed from those for participants instructed to produce word associations. Third, participants produced large amounts of information about background situations associated with the object cues, suggesting that the simulations used to generate properties were situated. The experiments ruled out alternative explanations that simulation effects occur only for familiar noun phrases associated with perceptual memories and that rules associated with modifiers produce occlusion effects. A process model of the property generation task grounded in simulation mechanisms is presented. The possibility of integrating the simulation account of conceptual combination with traditional accounts and well-established findings is explored.
