Validity and reliability of a Cantonese-translated rating of perceived exertion scale among Hong Kong adults

This study assessed the validity and reliability of the Cantonese-translated version of the Borg 6-20 Rating of Perceived Exertion (RPE) scale during continuous incremental cycle ergometry by Hong Kong adults. A total of 54 participants (25 males and 29 females), ages 22.2 +/- 4.7 yr., volunteered to participate. They performed two trials of identical continuous incremental cycling exercise 1 wk. apart for the reliability test. The objective measures of exercise intensity (heart rate, power output, and oxygen consumption) and the subjective measure of effort (RPE) were obtained during the incremental exercise. Significant (p < .01) Pearson correlations were found when RPE values were correlated with heart rate (rs > or = .73), power output (rs > or = .69), and oxygen consumption (rs > or = .68). The overall test-retest intraclass correlation (R = .92) indicated that the scale was reliable. In conclusion, this Cantonese scale for rating of perceived exertion appears to be a valid and reliable psychophysiological tool to measure perceptions of exertion during controlled cycle ergometer exercise by Hong Kong adults.     

Active navigation and orientation-free spatial representations

In this study, we examined the orientation dependency of spatial representations following various learning conditions. We assessed the spatial representations of human participants after they had learned a complex spatial layout via map learning, via navigating within a real environment, or via navigating through a virtual simulation of that environment. Performances were compared between conditions involving (1) multiple- versus single-body orientation, (2) active versus passive learning, and (3) high versus low levels of proprioceptive information. Following learning, the participants were required to produce directional judgments to target landmarks. Results showed that the participants developed orientation-specific spatial representations following map learning and passive learning, as indicated by better performance when tested from the initial learning orientation. These results suggest that neither the number of vantage points nor the level of proprioceptive information experienced are determining factors; rather, it is the active aspect of direct navigation that leads to the development of orientation-free representations.     

A genetic association with the development of alcohol and other substance use behavior in Asian Americans

Studies of Asian adults have found that alcohol use and alcohol dependence are related to variation in the aldehyde dehydrogenase (ALDH2) gene. To investigate the association of ALDH2 with the development of drug involvement, the authors analyzed retrospective information about the onset and regular use of alcohol and other substances as reported by 180 Asian American college students. Possession of an ALDH2*2 allele was not related to initiation of alcohol use or having ever been intoxicated, but individuals with ALDH2*2 alleles were less likely to be regular drinkers, were less likely to have engaged in a binge-drinking episode, reported a lower number of maximum drinks consumed in a 24-hr period, and were less likely to have used tobacco regularly than those without this genetic variant. These findings suggest that ALDH2 is associated with the development of not only alcohol-related behavior but other substance use behavior as well.     

Conflict resolution strategies of Hong Kong aggressive youth

Employing the Hong Kong Teenage Nonviolence Test, this study investigated 120 Hong Kong adolescents’ endorsement of various conflict resolution strategies as a function of gender and type of aggression. Results revealed all participants endorsed a moderately high level of using Empathy and Satyagraha (insistence on the truth) when faced with conflict. Moreover, the reactive-proactive aggressive youth reported a moderate degree of utilizing Physical-Psychological Violence to resolve conflict, while reactive aggressors and non-aggressors revealed a minimal amount of using this strategy. Additional studies are needed to further explore the relationship between aggression and various conflict resolution strategies. The findings can inform mental health professionals interested in designing programs to promote or reinforce protective or buffering factors (e.g., conflict resolution strategies) linked with proactive and reactive aggression.

When is search for meaning in life beneficial for well-being? A cross-national study

Previous research has found cross-national variations in the association between search for meaning in life (SMIL) and well-being (i.e. SMIL–WB link). This study extended and tested a “self-improvement hypothesis” that accounts for such cross-national variations based on an international database—the sixth wave of World Values Survey. SMIL represents a self-improvement effort which is more demanded in contexts with stronger external constraints. Thus, we expected a stronger positive SMIL–WB link in such contexts. A series of multilevel analyses was used to verify this hypothesis. The results showed that the SMIL–WB link varied across different societies, with well-being indexed by happiness, life satisfaction and subjective health. Moreover, external constraints from cultural, social-institutional, economic and ecological contexts (collectivism, peace threats, economic scarcity and environmental threats) moderated the SMIL–WB links. We thus call for advancing SMIL theory by considering person–context interaction.     

Finding meaning in us: The role of meaning in life in romantic relationships

The present research tested a model of relationship functioning that incorporates meaning in life (MIL), proposing that MIL plays an important role in individuals’ motivations and perceived quality of romantic relationships. Study 1 employed a weekly diary methodology (N = 121 individuals in romantic relationships) and found that both within- and between-person relationship MIL are associated with internalized motivational states (i.e. intrinsic motivation, harmonious passion) and relationship quality (i.e. satisfaction, commitment). Study 2 was a dyadic study that examined both members of romantic couples (N = 238 dyads). Results found that both one’s own and one’s partner’s MIL predict motivation and relationship quality. Further, we also found evidence of a hierarchical model of MIL, such that relationship-specific experiences of MIL mediate associations between general MIL and relationship motivation and quality. Taken together, this research provides consistent and compelling evidence regarding the importance of MIL in romantic relationships.     

Probabilistic versus “Pure” Volitional Orienting: a Monocular Difference

Human volitional orienting is typically assessed using Posner’s endogenous cuing task. As a volitional process, the literature has long emphasized the role of neocortical structures in this higher cognitive function. Based on recent data, we explored the possibility that subcortical channels may have a functional role in volitional orienting as measured by a Posner cuing task in which a nonspatial feature of a centrally presented cue is predictively related to the location of the target. In addition, we have compared this typical cuing task to a "purer" version, which does not involve the probability manipulation. A sensitive behavioral method was used to probe the contribution of monocular channels (mostly subcortical) in the two types of endogenous orienting tasks. In both tasks, a spatially informative cue and its ensuing target were presented to the same or different eyes at varying cue-target intervals. In the typically used endogenous task, the onset of facilitation was apparent earlier when the cue and target were presented to the same eye. In contrast, in the "pure" task no difference was found between the two eye-of-origin conditions. These data support the notion that endogenous facilitation, as measured in the typical Posner cuing task, involves lower monocular regions. Hence, in the typical endogenous task, which was developed to explore "volitional" orienting, a simple associative learning mechanism might elicit monocular, rapid orienting responses. Notably, the typical volitional orienting paradigm might be contaminated by simple contingency benefits and thus may not provide a pure measure of volitional processes.
