Consistent and variable practice conditions: effects on relative and absolute timing

The authors conducted the present experiments to resolve the discrepancy between studies in which relative-timing learning has been found to be enhanced by consistent practice conditions and contextual interference experiments in which relative-timing learning has been found to be enhanced more by random practice than by blocked practice. There were 40 participants in Experiment 1 and 48 in Experiment 2. The results of Experiment 1 extended previous findings: The learning of the relative-timing pattern was systematically enhanced by the degree to which the practice conditions promoted movement consistency (constant > blocked > serial > random). Experiment 2 provided evidence that the discrepancy between the relative-timing effects in the 2 groups of studies was a product of the way in which relative-timing goals and feedback were presented. When the feedback was presented as segment times, random practice resulted in generally more stable relative-timing patterns during acquisition than blocked practice did. Thus, in both experiments, the learning of the relative-timing pattern was enhanced by more stable relative-timing conditions during acquisition. Absolute-timing learning, as indexed by the transfer tests, was enhanced by serial or random practice as compared with constant or blocked practice, and was relatively unaffected by feedback conditions directed at the relative-timing pattern. In terms of motor programming theory, those findings are taken as additional evidence for the disassociation of memories supporting generalized motor program (GMP) performance, as indexed by relative timing, and parameter performance, as indexed by absolute timing.

The Significance of Family Structure in Internalizing (Anxious/Depressed) and Externalizing (Aggressive/Delinquent) Problems among Chinese Adolescents

The present pioneering study investigated the differences across various types of family structure among Chinese adolescents with proactive and reactive aggression. It aimed at providing frontline social workers and family therapists with inspirations for designing suitable interventions for adolescents with specific subtypes of aggressive behavior from different family structure backgrounds. After completing an online survey including the Reactive and Proactive Aggression Questionnaire (RPQ) and the subscales of the Child Behavior Checklist – Youth Self-report (CBCL-YSR) on aggressive behavior, delinquent behavior, and anxious/depressed symptom, 520 out of 13,338 Chinese adolescents aged 11 to 18 were randomly selected and stratified based on the types of family structure (intact family, single father family, single mother family, stepfather family, and stepmother family). Expectedly, boys elicited more proactive aggression, delinquent behaviors, and aggressive behaviors than girls. Besides, significant cross-structural differences were found between children from stepmother family, who showed more proactive aggression, anxious/depressed symptoms, aggressive behaviors, and delinquent behaviors, and those from intact family regardless of gender. The interaction effects between gender and family structure were significant for reactive aggression, anxious/depressed behavior, and aggressive behavior. An interaction effect showed boys from stepmother families were more reactively aggressive than those from intact families. In addition, more anxious/depressed symptoms were found in boys from stepmother family than those from intact and single mother families. In conclusion, the impacts of family structure on proactive aggression and delinquent behavior are not gender specific, but the impacts on reactive aggression and anxious/depressed behavior are only specific to boys.

     

Asymmetric goal contagion: Social power attenuates goal contagion among strangers

Goal contagion is an important interpersonal process. As people spontaneously infer and adopt others' goals, goals can be said to “flow” among individuals. We find that possessing power attenuates goal contagion, especially for high perspective takers. In a pilot study (N = 157), we first affirmed the interpersonal nature of goal contagion by establishing that high (vs. low) perspective takers were more likely to engage in goal contagion. We then tested the moderating role of power in two studies. In both neutral (Study 1, N = 179) and low power (Study 2, N = 304) conditions, we replicated the pattern in the pilot study. In the high power conditions, however, neither low nor high perspective takers engaged in goal contagion. Our findings suggest that goals flow asymmetrically from the powerful to the powerless, which may constitute an important means through which power hierarchy and group cohesion are maintained.     

How Do Coworkers “Make the Place”? Examining Coworker Conflict and the Value of Harmony in China and the United States

The goal of this study was to test cross‐cultural/cross‐national differences in the association between coworker interpersonal justice and coworker conflict and the implications of such differences for employee effectiveness. Harmony is a central value in China but is less important in the United States, and the individual value of harmony may influence Chinese and US employees differently in their response to low levels of coworker interpersonal justice. We collected data from employees and their coworkers in China (214 dyads) and the US (301 dyads). There were three major findings. First, coworker interpersonal justice was negatively related to coworker conflict. Second, coworker conflict significantly mediated coworker interpersonal justice in relation to the employee effectiveness variables of task performance, organisational citizenship behaviours, and counterproductive work behaviours. Finally, in the Chinese sample, harmony significantly buffered the indirect effect of coworker interpersonal justice on employee effectiveness via coworker conflict, whereas in the US sample, harmony significantly intensified the indirect effect of coworker interpersonal justice on employee effectiveness via coworker conflict.     

Gender and neural substrates subserving implicit processing of death-related linguistic cues

Our recent functional magnetic resonance imaging study revealed decreased activities in the anterior cingulate cortex (ACC) and bilateral insula for women during the implicit processing of death-related linguistic cues. Current work tested whether aforementioned activities are common for women and men and explored potential gender differences. We scanned twenty males while they performed a color-naming task on death-related, negative-valence, and neutral-valence words. Whole-brain analysis showed increased left frontal activity and decreased activities in the ACC and bilateral insula to death-related versus negative-valence words for both men and women. However, relative to women, men showed greater increased activity in the left middle frontal cortex and decreased activity in the right cerebellum to death-related versus negative-valence words. The results suggest, while implicit processing of death-related words is characterized with weakened sense of oneself for both women and men, men may recruit stronger cognitive regulation of emotion than women.     

Effects of perceptual and conceptual similarities on consumers' evaluations of copycat brand names

Copycats often choose brand names that mimic perceptual, conceptual, or both elements of leading brand names. Yet little is known about how perceptual and conceptual similarities of a copycat interact to affect consumers' evaluations, especially in logographic language systems (e.g., Chinese). Three laboratory experiments demonstrate that perceptual similarity alone leads to negative evaluations of copycat brand names; this negative effect, however, can be mitigated when conceptual similarity is added. The underlying mechanism for this effect can be traced to consumers' persuasion knowledge. Perceptual (vs. conceptual) similarity activates consumers' persuasion knowledge about the insincere motives of the copycat brand, which in turn shapes their brand evaluations. However, this effect can become less prominent when conceptual similarity is added because it alleviates use of persuasion knowledge, or when a consumer is in a happy mood because it neutralizes persuasion knowledge. These findings shed light on how different types of copycat strategies interact to affect copycat brand name evaluations and offer important implications for marketing practice.
