An empirical evaluation of the SYNWORK1 multiple-task work environment

SYNWORK1 is a multiple-task work environment that allows up to four tasks (memory search, arithmetic, visual monitoring, and auditory monitoring) to be performed concurrently. Experiments were conducted to evaluate performance and subjective workload for each individual task and all combinations of tasks at two presentation rates. At the slower default rates, the three experiment-paced tasks were not very demanding, and improvements with practice were due primarily to the subject-paced arithmetic task. Doubling the presentation rates made the demands of all tasks more comparable and decreased the influence of arithmetic performance. SYNWORK1 is useful for comparisons between populations of individuals and evaluations of arousal-related variables, and, with modification, could provide a tool for assessing basic issues in multiple-task performance.     

The Development and Validation of the Memory Support Treatment Provider Checklist

Patient memory for the contents of treatment is staggeringly poor, and poor memory for treatment is associated with worse treatment outcome. Accordingly, the Memory Support Intervention was developed to improve patient memory for treatment as an adjunct to treatment as usual. As plans to disseminate the Memory Support Intervention are developed, it is important to have efficient, accurate methods of measuring fidelity to the intervention. However, the existing method of assessing fidelity to the Memory Support Intervention, the Memory Support Rating Scale (MSRS), is burdensome and requires trained independent-raters to spend multiple hours reviewing session recordings, which is not feasible in many routine mental health care settings. Hence, a provider-rated measure of fidelity to the MSI has been developed. The goal of this study is to examine the reliability and validity of scores on this measure—the Memory Support Treatment Provider Checklist. A sample of Memory Support Treatment Provider Checklists (N = 319) were completed by providers (N = 8) treating adults with depression (N = 84). Three metrics of the Memory Support Treatment Provider Checklist were evaluated: (a) the internal consistency and structural validity using confirmatory factor analysis based on prior research on the MSRS and the Memory Support Intervention, (b) construct validity, and (c) predictive validity. Results indicate that the Memory Support Treatment Provider Checklist yields reliable and valid scores of fidelity to the Memory Support Intervention. Overall, this checklist offers a viable, brief method of evaluating fidelity to the Memory Support Intervention.     

Age differences in facial trustworthiness judgement based on multiple facial cues

Multiple facial cues such as facial expression and face gender simultaneously influence facial trustworthiness judgement in adults. The current work was to examine the effect of multiple facial cues on trustworthiness judgement across age groups. Eight-, 10-year-olds, and adults detect trustworthiness from happy and neutral adult faces (female and male faces) in Experiment 1. Experiment 2 included both adult and child faces wearing happy, angry, and neutral expressions. Nine-, 11-, 13-year-olds, and adults had to rate facial trustworthiness with a 7-point Likert scale. The results of Experiments 1 and 2 revealed that facial expression and face gender independently affected facial trustworthiness judgement in children aged 10 and below but simultaneously affected judgement in children aged 11 and above, adolescents, and adults. There was no own-age bias in children and adults. The results showed that children younger than 10 could not process multiple facial cues in the same manner as in older children and adults when judging trustworthiness. The current findings provide evidence for the stable-feature account, but not for the own-age bias account or the expertise account.     

Egocentric Distance Perception Disorder in Amblyopia

Egocentric distance perception is a psychological process in which observers use various depth cues to estimate the distance between a target and themselves. The impairment of basic visual function and treatment of amblyopia have been well documented. However, the disorder of egocentric distance perception of amblyopes is poorly understood. In this review, we describe the cognitive mechanism of egocentric distance perception, and then, we focus on empirical evidence for disorders in egocentric distance perception for amblyopes in the whole visual space. In the personal space (within 2 m), it is difficult for amblyopes to show normal hand-eye coordination; in the action space (within 2 m~30 m), amblyopes cannot accurately judge the distance of a target suspended in the air. Few studies have focused on the performance of amblyopes in the vista space (more than 30 m). Finally, five critical topics for future research are discussed: 1) it is necessary to systematically explore the mechanism of egocentric distance perception in all three spaces; 2) the laws of egocentric distance perception in moving objects for amblyopes should be explored; and 3) the comparison of three subtypes of amblyopia is still insufficient; 4) study the perception of distance under another theoretical framework; 5) explore the mechanisms of amblyopia by Virtual Reality.     

Culture in the Mediation of International Disputes

Unlike most treatments of culture in international diplomacy, this article suggests that culture can play a positive role in the mediation of international disputes. Cultural ties between the mediator and one or both of the disputants can facilitate mediation by, among other things, enhancing the mediator's acceptability to the parties, and enhancing the belief that the mediator can deliver concessions and agreements. Moreover, a mediator who is closer to one side than the other can be effective in mediation, especially when the mediator acts in an even‐handed manner. Data from laboratory research on mediation, as well as anecdotal evidence, support this view.     

A test of theory of planned behavior in Korea: participation in alcohol-related social gatherings

Two studies are reported using the theory of planned behavior (TPB) to predict and explain joining and not joining alcohol-related social gatherings among Korean undergraduates in various engineering majors. Specifically, considering that the attitudinal component of TPB is behavioral-outcome-based, the current study investigated whether the outcomes of engaging in a behavior and of not engaging in a behavior would similarly predict intentions to engage in a behavior and intentions to not engage in a behavior. The current study also examined whether intentions to engage and intentions to not engage would be significantly related to self-reported behavior a week later. Participants in Study 1 reported TPB components (attitudes toward behavior, subjective norms, perceived behavioral control, and behavioral intentions) concerning joining alcohol-related social gatherings. Participants in Study 2 reported TPB components concerning not joining alcohol-related social gatherings. Additionally, a week later, the participants in both studies reported their participation in alcohol-related social gatherings from the past week. Generally, the results showed that the TPB components were significantly associated with undergraduates' intentions to join and intentions to not join. Specifically, conversation-related attitudes and senior-junior relationship-related attitudes were significantly related to intentions to join, and only group-related attitudes were significantly related to intentions to not join. Intentions to join and intentions to not join were not significantly related to self-reported behavior of joining alcohol-related social gatherings a week later. The findings from the current research provide some evidence that joining or not joining alcohol-related social gatherings may not be mere behavioral opposites, predictable by the presence or absence of the same behavioral outcomes. These two aspects of the behavior may require assessment of different behavioral outcomes or different assessments of the same behavioral outcomes.     

What can I gain as a mentor? The effect of mentoring on the job performance and social status of mentors in China

In this study, we examine how mentoring benefits mentors as well as how team cohesiveness affects mentoring relationships and resulting benefits. We followed 512 formal mentors in a Chinese manufacturing firm for six months and collected data in three phases and from three sources. The findings reveal that the amount of mentoring provided is positively related to mentors' in‐role job performance and social status. These relationships were fully mediated by mentors' personal learning and social interaction quality, respectively. Team cohesiveness, however, did not moderate these relationships. Our empirical findings have implications for understanding how mentors' careers can benefit from being a mentor.

Effect of Heel Heights on Female Postural Control During Standing on a Dynamic Support Surface With Sinusoidal Oscillations

The authors aimed to investigate female balance or stability control with comparative analysis of the center of pressure trajectory and plantar pressure distribution with different high-heeled shoes while standing on a dynamic surface with multidirectional perturbations. College females with at least 2 years' history of wearing high-heel shoes voluntarily participated in the test with a Novel Pedar insole (Novel, GmBH, Munich, Germany. With heels height increasing, the pressure time integral obviously transfer to the medial forefoot region, with center of pressure trajectory medially deviated significantly, either under anteroposterior or mediolateral perturbations. The passive plantarflexion position of ankle incurred by high heel increased the range of motion in the frontal plane but decreased ankle stability, thus increasing the challenge of body balance maintenance.
