The face of fluency: Semantic coherence automatically elicits a specific pattern of facial muscle reactions

This study shows that high conceptual fluency induced by hidden semantic coherence automatically triggers a specific pattern of facial expressions. In the present study, word triads that either had or had not a common remote associate were read by individuals while automatic facial responses were recorded. Although participants were ignorant about the underlying semantic structure, participants’ faces showed an activation of the smiling muscle zygomaticus major (indicating increased positive affect), a relaxation of the frowning muscle corrugator supercilii (indicating decreased negative affect and mental effort), and a relaxation of the forehead muscle frontalis (indicating increased familiarity) after reading coherent compared to incoherent word triads. Implications for intuitive judgements of semantic coherence are discussed.     

The Experiences of Self-Injury Amongst Adolescents and Young Adults within a South African Context

The aim of the study was to explore the experiences of self-injury among adolescents and young adults within the South African context. The participants were twelve university students who had self-injured in their adolescence (females = 92%). The data were collected through interviews, personal writings and collages and analysed using phenomenological data analysis. The findings indicate that self-injury is a strategy used to alleviate intense intrapersonal and interpersonal distress. To understand the complexity of self-injury, an integrative theoretical approach, encompassing a developmental and biopsychosocial perspective was used.     

Evaluation of fixed momentary dro schedules under signaled and unsignaled arrangements

Fixed momentary schedules of differential reinforcement of other behavior (FM DRO) generally have been ineffective as treatment for problem behavior. Because most early research on FM DRO included presentation of a signal at the end of the DRO interval, it is unclear whether the limited effects of FM DRO were due to (a) the momentary response requirement of the schedule per se or (b) discrimination of the contingency made more salient by the signal. To separate these two potential influences, we compared the effects of signaled versus unsignaled FM DRO with 4 individuals with developmental disabilities whose problem behavior was maintained by social-positive reinforcement. During signaled FM DRO, the experimenter presented a visual stimulus 3 s prior to the end of the DRO interval and delivered reinforcement contingent on the absence of problem behavior at the second the interval elapsed. Unsignaled DRO was identical except that interval termination was not signaled. Results indicated that signaled FM DRO was effective in decreasing 2 subjects' problem behavior, whereas an unsignaled schedule was required for the remaining 2 subjects. These results suggest that the response requirement per se of FM DRO may not be problematic if it is not easily discriminated.     

Identifying Cheating on Unproctored Internet Tests: The Z‐test and the likelihood ratio test

Unproctored Internet testing (UIT) is becoming more popular in employment settings due to its cost effectiveness and efficiency. However, one of the major concerns with UIT is the possibility of cheating behaviors: a more capable conspirator can sit beside the real applicant and answer test items, or the applicant may use unauthorized materials. The present study examined the effectiveness of using a proctored verification test following the UIT to identify cheating in UIT, where 2 test statistics, a Z‐test and a likelihood ratio (LR) test, compare the consistency of test performance across the testing conditions. A simulation study was conducted to test the effectiveness of the two test statistics for a computerized adaptive test format. Results indicate that both test statistics have high power to detect dishonest job applicants at low Type I error rates. Compared with the LR test, the Z‐test was more efficient and effective and is therefore recommended for practical applications. The theoretical and practical implications are discussed.     

Job stressors, emotional exhaustion, and need for recovery: A multi-source study on the benefits of psychological detachment

This paper examines psychological detachment (i.e., mentally “switching off”) from work during non-work time as a partial mediator between job stressors and low work-home boundaries on the one hand and strain reactions (emotional exhaustion, need for recovery) on the other hand. Survey data were collected from a sample of protestant pastors (N = 136) and their spouses (N = 97). Analyses showed that high workload, emotional dissonance, and low spatial work-home boundaries were related to poor psychological detachment from work during non-work time. Poor psychological detachment in turn predicted high levels of emotional exhaustion and need for recovery. Psychological detachment was a partial mediator between job stressors and strain reactions. This study avoids same-source bias and demonstrates the importance of psychological detachment in the stressor–strain relationship.     

Effects of number and location of bins on plastic recycling at a university

The proportion of plastic bottles that consumers placed in appropriate recycling receptacles rather than trash bins was examined across 3 buildings on a university campus. We extended previous research on interventions to increase recycling by controlling the number of recycling receptacles across conditions and by examining receptacle location without the use of posted signs. Manipulating the appearance or number of recycling bins in common areas did not increase recycling. Consumers recycled substantially more plastic bottles when the recycling bins were located in classrooms.     

Culture,essentialism, and agency: are individuals universally believed to be more real entities than groups?

Are human individuals universally seen to be more real entities (or more entitative, to use Campbell's, 1958, term) than social groups? Although the individual may be seen to be more entitative than social groups in the West, it is unclear whether this is the case in other cultures, especially in East Asia. Two aspects of perceived entitativity are distinguished: psychological essentialism (belief in the presence of essence‐like unchangeable properties) and agency (perception that a social entity is an agent), and examined for four social targets (individual, family, friendship group, and society) in three English‐speaking cultures (Australia, UK, and USA), three East Asian cultures (Hong Kong, Japan, and Korea), and two continental European cultures (Belgium and Germany). In all cultures, the individual person was seen to possess essence‐like unchangeable characteristics more than social groups (i.e. essentialized). As for agency, the individual person was seen to be more agentic than groups in Western cultures, but both individuals and groups were conferred an equal level of agency in East Asia. Individuals may be universally more essentialized than friendship groups and societies, but not always seen to be more agentic, than social groups. Implications of the results for conceptions of individualism and collectivism are discussed. Copyright © 2004 John Wiley & Sons, Ltd.     

Diaphragmatic breathing as treatment for escape‐maintained aggression

Coping skills, such as diaphragmatic breathing, are commonly recommended to help individuals work through challenging situations. We evaluated diaphragmatic breathing as treatment for aggression of three individuals diagnosed with autism spectrum disorder or Angelman syndrome. Functional analysis results demonstrated that each participant engaged in aggression maintained by social‐negative reinforcement. Diaphragmatic breathing treatment without extinction was conducted in a work context and involved prompting diaphragmatic breathing contingent on precursors to aggression; treatment was effective in reducing the rate of aggression for one of three participants. For the two other participants, other reinforcement‐based interventions (differential reinforcement of other behavior or functional communication training with extinction) were necessary to decrease aggression.     

Movement direction or change in distance? Self- and object-related approach-avoidance motions

Based on the conceptualization of approach as a decrease in distance and avoidance as an increase in distance, we predicted that stimuli with positive valence facilitate behavior for either approaching the stimulus (object as reference point) or for bringing the stimulus closer (self as reference point) and that stimuli with negative valence facilitate behavior for withdrawing from the stimulus or for pushing the stimulus away. In Study 1, we found that motions to and from a computer screen where positive and negative words were presented lead to compatibility effects indicative of an object-related frame of reference. In Study 2, we replicated this finding using social stimuli with different evaluative associations (young vs. old persons). Finally, we present evidence that self vs. object reference points can be induced through instruction and thus lead to opposite compatibility effects even when participants make the same objective motion (Study 3).
