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.     

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.     

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.

Social Cynicism and Job Satisfaction: A Longitudinal Analysis

Social cynicism, a negative view about people and social institutions, was found to show a negative correlation with job satisfaction across societies. A preliminary study in Hong Kong showed that social cynicism and job satisfaction correlated negatively across individuals as well. To confirm the causal effect of social cynicism on job satisfaction, a longitudinal study in Shanghai, China, with three waves of surveys, was conducted. Results showed that social cynicism correlated negatively with job satisfaction measured concurrently, and was predictive of job satisfaction measured subsequently. Consistent with the buffering hypothesis, perceived well‐being was a significant moderator in that the negative relationship between social cynicism and job satisfaction was significant only when perceived well‐being was low. On s'est aperçu que le cynisme social (une vision négative des gens et des institutions sociales) entretenait une corrélation négative avec la satisfaction professionnelle quelle que soit la société. Une étude préliminaire à Hong‐Kong a montré que le cynisme social et la satisfaction professionnelle présentaient également une corrélation négative au niveau de l'individu. Dans le but de confirmer le statut causal du cynisme social sur la satisfaction professionnelle, on a mené une étude longitudinale en Chine, à Shanghai, avec trois enquêtes successives. Les résultats montrent que le cynisme social est négativement reliéà la satisfaction professionnelle mesurée au même moment et prédit la satisfaction professionnelle mesurée ultérieurement. En accord avec l'hypothèse portant sur la résistance aux aléas de l'existence, le bien‐être perçu est un modérateur actif dans la mesure où la relation négative entre le cynisme social et la satisfaction professionnelle n'est significative que lorsque le bien‐être perçu est médiocre.     

Effects of relative embodiment in lexical and semantic processing of verbs

Research examining semantic richness effects in visual word recognition has shown that multiple dimensions of meaning are activated in the process of word recognition (e.g., Yap et al., 2012). This research has, however, been limited to nouns. In the present research we extended the semantic richness approach to verb stimuli in order to investigate how verb meanings are represented. We characterized a dimension of relative embodiment for verbs, based on the bodily sense described by Borghi and Cimatti (2010), and collected ratings on that dimension for 687 English verbs. The relative embodiment ratings revealed that bodily experience was judged to be more important to the meanings of some verbs (e.g., dance, breathe) than to others (e.g., evaporate, expect). We then tested the effects of relative embodiment and imageability on verb processing in lexical decision (Experiment 1), action picture naming (Experiment 2), and syntactic classification (Experiment 3). In all three experiments results showed facilitatory effects of relative embodiment, but not imageability: latencies were faster for relatively more embodied verbs, even after several other lexical variables were controlled. The results suggest that relative embodiment is an important aspect of verb meaning, and that the semantic richness approach holds promise as a strategy for investigating other aspects of verb meaning.     

Religious education programme of the Catholic Church in Hong Kong: Challenges and responses since 1997

The Catholic Church, the largest school-sponsoring body in Hong Kong, is a major provider of religious schools and educational programmes. In 2006, the Catholic Diocese released its first centralised and comprehensive curricular document concerning religious and moral education (RME) in Catholic schools. Taking this programme as a reflection of the Church’s response to the challenges of a changing social milieu, severed church–state relations and shortcomings in Catholic education in post-1997 Hong Kong, this article reviews the framework and principles of the new curriculum. While retaining strong religious elements in its curriculum, the Catholic Church has widened and re-oriented its programme, and re-designed the contents and pedagogical methods. The new programme is characterised by adjustment and differentiation, upholding Christian faith, and selective absorption of Chinese culture. This article also discusses problems in the implementation of the new programme, including organisational compartmentalisation and an underdeveloped political dimension in the content.     

The Effects of a Female Role Model on Academic Performance and Persistence of Women in STEM Courses

Women are more likely to leave science, technology, engineering, and mathematics compared to men, in part because they lack similar role models such as peers, teaching assistants, and instructors. We examined the effect of a brief, scalable online intervention that consisted of a letter from a female role model who normalized concerns about belonging, presented time spent on academics as an investment, and exemplified overcoming challenges on academic performance and persistence. The intervention was implemented in introductory psychology (Study 1, N?=?258) and chemistry (Study 2, N?=?68) courses. Relative to the control group, the intervention group had higher grades and lower failing and withdrawal rates.     

No evidence of risk-taking or impulsive behaviour in a person with episodic amnesia: Implications for the role of the hippocampus in future-regarding decision-making

Does advantageous decision-making require one to explicitly remember the outcome of a series of past decisions or to imagine future personal consequences of one's choices? Findings that amnesic people with hippocampal damage cannot form a clear preference for advantageous decks over many learning trials on the Iowa Gambling Task (IGT) have been taken to suggest that complex decision-making on the IGT depends on declarative (episodic) memory and hippocampal integrity. Alternatively, impaired IGT performance in amnesic individuals could be secondary to risk-taking and/or impulsive behaviour resulting from impaired episodic future thinking (i.e. prospection) known to accompany amnesia. We tested this possibility in the amnesic individual K.C. using the IGT and the Toronto Gambling Task (TGT), a novel task that dissociates impulsivity from risk-taking without placing demands on declarative memory. K.C. did not develop a preference for advantageous over disadvantageous decks on the IGT and, instead, showed a slight preference for short-term gains and an inability to acquire a more adaptive appreciation of longer-term losses. He also did not display impulsive or risk-taking behaviour on the TGT, despite a profound inability to imagine personal future experiences. These findings suggest that impaired decision-making on the IGT in amnesia is unlikely to reflect a predilection to act in the moment or failure to take future consequences into account. Instead, some forms of future-regarding decision-making may be dissociable, with performance on tasks relying on declarative learning or on episodic-constructive processes more likely to be impaired.
