Life Satisfaction and Self-Assessed Health Among Adolescents in Hong Kong

Self-assessed health in four items of the Health Related Quality of Life Scale, overall health, physical health, mental health, and activity limitation, and perceived life satisfaction in six domains of the Brief Multidimensional Students’ Life Satisfaction Scale, overall life, family life, friendships, school experience, myself, and where I live were examined among 4,502 Chinese adolescent secondary school students in Hong Kong. Relative to the US adolescents in Youth Risk Behavior Survey the Hong Kong adolescents had very low levels of self-assessed health and life satisfaction. Among the different domains, family and school life were associated with the lowest satisfaction level. There were strong male advantages in self-assessed health and migrant disadvantages in life satisfaction. Age was negatively related to both health and life satisfaction. Two-parent family was a positive factor for adolescents’ quality of life but economic well-being was not a relevant factor.     

Minority Influence, Divergent Thinking and Detection of Correct Solutions

In many applied settings involving influence processes in small groups, the interest is in how such processes aid or hinder effective decision making and problem solving. In a recent formulation, Nemeth (1986) argued that exposure to opposing views emanating from a minority leads to divergent thinking, a process that involves a consideration of the problem from varying viewpoints. On balance, such influence would aid performance. Exposure to opposing majority viewpoints leads to convergent thought where S s presumably concentrate on the proposed viewpoint to the exclusion of other considerations. On balance, this form of influence tends not to aid performance and may prove to be an impediment. In the present study, these hypotheses were tested in the context of anagram solutions. Results showed that subjects exposed to the minority viewpoint found more correct words and they achieved this superior performance by a usage of all possible strategies. Subjects exposed to the majority viewpoint initially used the strategy suggested by the majority to the detriment of other strategies and, in general, performed at the level of control subjects. These results are discussed in terms of potential contributions made by exposure to dissenting minority viewpoints in small group decision-making settings such as trial by jury and in society at large.     

Do people agree about the causes of behavior? A social relations analysis of behavior ratings and causal attributions

Two studies examined consistency and agreement in behavior ratings and causal attributions. In Study 1, participants (N = 280) engaged in a series of getting-acquainted conversations in one of 3 communication media (face-to-face, telephone, computer mediated); in Study 2, participants (N = 120) engaged in a competitive group task. In both studies, participants rated themselves and their interaction partners on a set of behaviors and then made attributions about the causes of those behaviors. The major findings were that (a) participants consistently favored some causal factors over others in explaining both their own and their partners' behavior, supporting the existence of generalized attributional styles; and (b) participants showed moderate self-partner and partner-partner agreement about behavior but virtually no agreement about the causes of behavior. Thus, in brief interactions people tend to see themselves and others through the lens of their stable patterns of perceiving and interpreting behavior.     

Spatial representation of pitch height: the SMARC effect

Through the preferential pairing of response positions to pitch, here we show that the internal representation of pitch height is spatial in nature and affects performance, especially in musically trained participants, when response alternatives are either vertically or horizontally aligned. The finding that our cognitive system maps pitch height onto an internal representation of space, which in turn affects motor performance even when this perceptual attribute is irrelevant to the task, extends previous studies on auditory perception and suggests an interesting analogy between music perception and mathematical cognition. Both the basic elements of mathematical cognition (i.e. numbers) and the basic elements of musical cognition (i.e. pitches), appear to be mapped onto a mental spatial representation in a way that affects motor performance.     

Hiding and finding: The relationship between visual concealment and visual search

As an initial step toward developing a theory of visual concealment, we assessed whether people would use factors known to influence visual search difficulty when the degree of concealment of objects among distractors was varied. In Experiment 1, participants arranged search objects (shapes, emotional faces, and graphemes) to create displays in which the targets were in plain sight but were either easy or hard to find. Analyses of easy and hard displays created during Experiment 1 revealed that the participants reliably used factors known to influence search difficulty (e.g., eccentricity, target—distractor similarity, presence/absence of a feature) to vary the difficulty of search across displays. In Experiment 2, a new participant group searched for the targets in the displays created by the participants in Experiment 1. Results indicated that search was more difficult in the hard than in the easy condition. In Experiments 3 and 4, participants used presence versus absence of a feature to vary search difficulty with several novel stimulus sets. Taken together, the results reveal a close link between the factors that govern concealment and the factors known to influence search difficulty, suggesting that a visual search theory can be extended to form the basis of a theory of visual concealment.     

Vaginal scent marking: effects on ultrasonic calling and attraction of male golden hamsters

Male hamsters were tested for their responses to areas that had been scent marked by intact or vaginectomized females to determine the effects of naturally deposited vaginal secretions on male behavior. In the first experiment males produced more ultrasonic courtship calls when investigating areas marked by intact females than areas scented by vaginectomized females, demonstrating that vaginal marks facilitate such calling. In a wind-tunnel preference test situation in which scent-marked alleys and clean alleys served as sources of odor, males approached the scented alley first if it had been freshly marked by intact females but not if it had been scented by vaginectomized females or other males. Thus, the odors of vaginal marks are sufficient to attract males over short distances. After males entered these alleys they showed a preference for odors of both intact and vaginectomized females over no odors, but still spent significantly more time investigating the odors of intact females than those of vaginectomized females. These experiments indicate that vaginal secretions are one of the primary cues that elicit male courtship calling, and the small quantities of vaginal secretions deposited by females in vaginal marks are sufficient to elicit ultrasonic calling and attract males over short distances. Thus it is likely that vaginal scent marking and ultrasonic calling by females interact to facilitate attraction and location of mates during courtship.     

Clinical Efficacy of Ritual Healing and Pastoral Ministry

This article seeks to explain the relationship between religion and healing with special reference to the phenomenon of ritual healing. Relying on diverse research findings that articulate the relationship between ritual and healing, this article contends that the clinical efficacy of ritual is sustainable by invoking the concepts of self-healing and placebo effect, and that its efficacy lies in its performance, not in its meaning being either decodable by the ritual performers or theologically encodable by professional thinkers. This, I contend, has practical implications for pastoral care and counseling ministry.

Calcium channel antagonists enhance retention of passive avoidance and maze learning in mice

Although a number of studies have shown that treatment with calcium channel antagonists (CCAs) can ameliorate impairments in learning and memory in aged animals, evidence for a general nootropic effect of CCAs in neurologically normal young adult animals is ambiguous. This study attempts to resolve some of this ambiguity by comparing the effects of several CCAs on retention of passive avoidance learning and acquisition and retention of appetitively motivated spatial discrimination learning in young adult mice. Animals were trained in a step through passive avoidance apparatus and, immediately after training, injected subcutaneously with different doses of nimodipine, nifedipine, amlodipine, flunarazine, diltiazem, or verapamil. Retention was tested 24 h after training. In the maze-learning task mice were treated with the same doses of the aforementioned CCAs immediately after a brief training session in a linear maze and retention was tested 24 h after training. The most effective dose of each agent in the maze-retention experiment was administered to additional groups of animals 1 h prior to training to determine the effects of CCAs on acquisition processes. The effects of central administration of CCAs were examined by intracerebroventricular injection of different doses of amlodipine immediately after passive avoidance training. Results showed (1) all peripherally administered drugs except verapamil facilitated retention of passive avoidance training in a dose-dependent manner, (2) all drugs dose dependently facilitated retention of linear maze learning, (3) all doses of the drugs (except verapamil) which facilitated maze retention also facilitated maze learning, and (4) central administration of the dihydropyridine amlodipine produced a dose-dependent facilitation of the retention of passive avoidance learning. These data indicate that drugs which block calcium channels can enhance retention of two different types of learning in mice.
