Is cleanliness next to abstinence? The effect of cleanliness priming on attitudes towards harm reduction strategies for people with substance use disorders

Can exposure to a cleanliness prime affect moral judgements towards harm reduction strategies (HRS) for individuals with substance use disorders? Our research examined (a) the effect of a cleanliness prime on attitudes towards HRS and (b) whether this effect would be attenuated by a brief educational presentation. Participants were randomly assigned to a priming condition and an educational presentation condition. Results demonstrated that (a) the cleanliness prime did not shift attitudes towards HRS, however, (b) the educational presentations significantly shifted attitudes to be more positive after the Harm Reduction presentation and more negative after the Healthy Living presentation. The literature on priming is mixed and our results support a growing body of research challenging the robustness of cleanliness priming and also demonstrates that brief presentations can change attitudes. Our research has implications for education on the benefits of HRS in reducing disease transmission, refuse in the community, and overdose deaths.     

Priming effects of arithmetic signs in 10- to 15-year-old children

In this research, 10- to 12- and 13- to 15-year-old children were presented with very simple addition and multiplication problems involving operands from 1 to 4. Critically, the arithmetic sign was presented before the operands in half of the trials, whereas it was presented at the same time as the operands in the other half. Our results indicate that presenting the ‘x’ sign before the operands of a multiplication problem does not speed up the solving process, irrespective of the age of children. In contrast, presenting the ‘+’ sign before the operands of an addition problem facilitates the solving process, but only in 13 to 15-year-old children. Such priming effects of the arithmetic sign have been previously interpreted as the result of a pre-activation of an automated counting procedure, which can be applied as soon as the operands are presented. Therefore, our results echo previous conclusions of the literature that simple additions but not multiplications can be solved by fast counting procedures. More importantly, we show here that these procedures are possibly convoked automatically by children after the age of 13 years. At a more theoretical level, our results do not support the theory that simple additions are solved through retrieval of the answers from long-term memory by experts. Rather, the development of expertise for mental addition would consist in an acceleration of procedures until automatization.     

Multiple factors of cognitive failure and their relationships with stress vulnerability

Use of the Cognitive Failures Questionnaire (CFQ) in clinical research assumes that the questionnaire measures a single factor. A factor analysis of the CFQ was performed, on a sample of 475 students, using accurate procedures for determining the number of factors. These procedures gave mutually inconsistent results: at least two alternative factor structures can be extracted from the CFQ. An interpretable seven factor solution was found, but the CFQ probably has insufficient items to measure more than two strongly defined factors. The capacity of CFQ multiple factors to predict measures related to stress vulnerability was tested in a further study (N=57). Correlations between CFQ total score and neuroticism and use of coping strategies appeared to depend mainly on a single CFQ multiple factor, related to failures of concentration. Some of the other CFQ factors predicted other criteria. Further research on multiple factors of cognitive failure might improve the validity of the CFQ as a predictor of stress vulnerability and of cognitive performance.     

情绪劳动策略对主动破坏行为的影响

如何开展员工情绪劳动管理,避免负面行为结果,是服务行业面对的重要问题。以788名呼叫中心员工为研究对象,本文获得的结果表明:1)表层动作显著促进主动破坏行为,而深层动作的影响不显著。2)政策强度感知显著调节表层动作与主动破坏行为间关系;当政策强度感知较低时,表层动作对主动破坏行为的正向影响更为显著。3)情感社会分享显著调节深层动作与主动破坏行为间关系;当情感社会分享水平较高时,深层动作对主动破坏行为的负向影响更为显著。本研究从资源保存视角提出工作场所开展情绪劳动管理的有效策略。

Representation and Reasoning about Evolutions of the World in the Context of Reasoning about Actions

The first step in reasoning about actions and change involves reasoning about how the world would evolve if a certain action is executed in a certain state. Most research on this assumes the evolution to be only a single step and focus on formulating the transition function that defines changes between states due to actions. In this paper we consider cases where the evolution is more than just a single change between one state and another. This is manifested when the execution of an action may trigger execution of other actions, or when multiple agents act on the environment following certain strategies.     

Social support,coping, and psychological adjustment among caregivers of head-injured patients

Abstract

The purpose of this study was to test a mediational model of risk and protective factors associated with the psychological adjustment of caregivers of head-injured patients. Forty-three caregivers of patients who had suffered a head injury participated in the study. Findings strongly supported hypotheses. Caregiver burden was associated with poorer psychological adjustment. Social support and a higher percentage of approach coping strategies relative to overall coping strategies were associated with better psychological adjustment. As predicted, caregiver burden showed a direct relationship to psychological adjustment, while social support showed an indirect relationship to adjustment mediated by percentage approach coping.     

Spreading the words: A spacing effect in vocabulary learning

The spacing effect refers to the frequently observed finding that distributing learning across time leads to better retention than massing it into one single study session. In the present study, we examined whether the spacing effect generalises to primary school vocabulary learning. To this aim, children from Grade 3 were taught the meaning of 15 new words using a massed procedure and 15 other new words using a spaced procedure. The 15 words in the massed condition were divided into three sets of five words, and each set was taught three times in one of three learning sessions. In the spaced condition, learning was distributed across the three sessions: All 15 words were practised once in each of the three learning sessions. At the retention tests after 1 week and after 5 weeks we observed that the meaning of spaced words was remembered better than the meaning of massed words.
