The immediate and sustained effects of acute exercise on planning aspect of executive function

ObjectiveThe purpose of this study was to clarify the immediate and sustained effects of an acute bout of exercise on the planning aspects of executive function.DesignThis study used a 2 × 4 true experimental design.MethodForty participants were randomly assigned to either the exercise or control groups and completed the Tower of London task prior to, immediately following, 30 min after, and 60 min after cessation of a 30 min, moderate intensity cycling exercise.ResultsAcute exercise positively impacted the total move score, which reflects planning efficiency, immediately after the cessation of exercise. Acute exercise also led to longer total initiation times, which were linked to better response inhibition of planning at 30 and 60 min after the cessation of exercise.ConclusionAcute exercise benefits planning, and the types of planning and the time points at which they were assessed modulate the relationship between acute exercise and executive function. Exercise-induced physiological and biological fluctuations have been proposed to explain the effects present immediately after exercise, and the mechanisms of such effects warrant further exploration.     

Structure of a cubic phase related to Cd?Mg?rare-earth quasicrystals

The structure of a Cd₆₈Mg₁₂Dy₂₀ crystalline phase denoted as the φ-phase, which has a composition close to that of the Cd₆₆Mg₂₁Dy₁₃ icosahedral quasicrystalline phase, has been investigated by electron diffraction and scanning transmission electron microscopy (STEM). The φ phase has a fcc lattice with a = 21.6Å. High-angle annular dark-field STEM with Z contrast confirms that the phase has the Cd₄₅Sm₁₁-type structure. The atomic cluster in the structure is shown to be characterized by a Friauf polyhedron with tetrahedral symmetry.     

When does feeling of fluency matter?: how abstract and concrete thinking influence fluency effects

It has been widely documented that fluency (ease of information processing) increases positive evaluation. We proposed and demonstrated in three studies that this was not the case when people construed objects abstractly rather than concretely. Specifically, we found that priming people to think abstractly mitigated the effect of fluency on subsequent evaluative judgments (Studies 1 and 2). However, when feelings such as fluency were understood to be signals of value, fluency increased liking in people primed to think abstractly (Study 3). These results suggest that abstract thinking helps distinguish central decision inputs from less important incidental inputs, whereas concrete thinking does not make such a distinction. Thus, abstract thinking can augment or attenuate fluency effects, depending on whether fluency is considered important or incidental information, respectively.     

Taiwanese members' report of verbal interactions and their relations to demographic variables in the group counseling process

The purpose was to examine differences in verbal interactions during the group counseling process and the relationship between perceived verbal interactions and members' demographic variables. 42 participants were recruited and randomly assigned to one of four counseling groups. Based on the Hill Interaction Matrix, Quadrant 4 verbal interactions, consisting of Speculative and Confrontative verbal behaviors in Personal and Relationship levels, were perceived significantly more often at the closing stage than at the initial stage. Furthermore, the perceived verbal interactions were related to the demographic variables of sex, educational level, and group experience, but not acquaintanceship. The findings suggested that the higher ratings of perceived Speculative and Confrontative verbal behaviors and the lower ratings of Assertive and Silence verbal interactions must be interpreted cautiously from a cross-cultural perspective, especially in Asian cultures.     

The GROOP effect: groups mimic group actions

Research on perception–action links has focused on an interpersonal level, demonstrating effects of observing individual actions on performance. The present study investigated perception–action matching at an inter-group level. Pairs of participants responded to hand movements that were performed by two individuals who used one hand each or they responded to hand movements performed by an individual who used both hands. Apart from the difference in the number of observed agents, the observed hand movements were identical. If co-actors form action plans that specify the actions to be performed jointly, then participants should have a stronger tendency to mimic group actions than individual actions. Confirming this prediction, the results showed larger mimicry effects when groups responded to group actions than when groups responded to otherwise identical individual actions. This suggests that representations of joint tasks modulate automatic perception–action links and facilitate mimicry at an inter-group level.     

Advisory working alliance, perceived English proficiency, and acculturative stress

The aim of this study was to examine the moderators of (a) general or cross-cultural advisory working alliances and (b) perceived English proficiency on the association between acculturative stress and psychological distress. A total of 143 East Asian international students completed an online survey. Results from a hierarchical regression indicated significant three-way interactions of (a) General Advisory Working Alliances × Perceived English Proficiency × Acculturative Stress on Psychological Distress and (b) Cross-Cultural Advisory Working Alliances × Perceived English Proficiency × Acculturative Stress on Psychological Distress. Specifically, the present results indicated that acculturative stress was significantly associated with psychological distress only when students perceived lower English proficiency and had a stronger general or cross-cultural advisory working alliance. However, acculturative stress was not significantly related to psychological distress when these students perceived lower English proficiency and had a weaker advisory working alliance (i.e., general or cross-cultural). In addition, acculturative stress was also not significantly related to psychological distress when these students perceived higher English proficiency and had a stronger or weaker advisory working alliance (i.e., general or cross-cultural).     

Overpredicting and Underprofiting in Pricing Decisions

This research examines sellers' price‐setting behavior and discovers a naturally occurring mismatch between sellers and buyers: Sellers who make a price decision often consider alternative prices and engage in the joint evaluation mode, whereas buyers who make a purchase decision see only the finally set price and are in the single evaluation mode. This mismatch in evaluation modes leads sellers to overpredict buyers' price sensitivity and underprice their products. However, these effects apply only to products unfamiliar to buyers and without salient reference prices and can be alleviated if sellers are encouraged to mimic single evaluation when making pricing decisions. These propositions are empirically tested and verified. Copyright © 2011 John Wiley & Sons, Ltd.     

The Joint Moderating Effects of Activated Negative Moods and Group Voice Climate on the Relationship between Power Distance Orientation and Employee Voice Behavior

Employees inherently have concerns about the consequences of speaking up, and this is particularly notable for employees with high power distance orientation (PDO). Drawing on ideas from the dual‐pathway model of mood and social information processing theory, we propose that activated negative mood and group voice climate can synergistically facilitate high‐PDO employees' voice behaviors. Using a sample from 305 real‐estate sales agents in 66 work groups in Taiwan, we examined the joint moderating effects of activated negative mood and group voice climate on employees' two forms of voice behavior. Our results show that PDO had a negative relationship with promotive voice but did not have a significant relationship with prohibitive voice. Nevertheless, our results show that in the situation where both activated negative mood and group voice climate were high, PDO no longer had a negative relationship with promotive voice, and even had a positive relationship with prohibitive voice. The findings of this study provide theoretical insights for the voice literature and offer practical suggestions for facilitating opinion expression in organisations.
