高创造力个体的群体差异性研究

高创造力群体的界定是创造力研究的重要前提,但迄今极少有研究关注以往研究中高创造力群体间的同质性问题。本研究以创造力问题提出能力测验调查了两所高校（一所地方高校和一所教育部直属高校）的975名大学生的创造力,通过极端组方法（extreme groups approach, EGA）为大学生创造力水平分组,考察不同创造力分组之间的差别。研究发现：地方高校和部属高校的高创造力大学生被试,在创造力的流畅性、变通性和独特性三个维度上,均存在显著差异。本研究结果提示,大学生高创造力组间可能存在质的差别,因此相关研究在外推结果时需要采取谨慎态度;研究者在实验过程中和讨论文献结果的可比性时一定要关注样本的同质性问题。     

Effects of minority status in the classroom on children's intergroup attitudes

Three studies examined the effects of relative group size on the development of children's intergroup attitudes. The studies employed a novel group paradigm in which elementary school children attending a summer school program were assigned to larger (i.e., majority) or smaller (i.e., minority) novel groups in their classroom (denoted by colored tee-shirts). In each study, relative group size was situated within a different classroom context. Study 1 examined the effects of relative group size when teachers made functional use of the novel groups and were themselves members of the novel groups. Study 2 examined the effects of relative group size in the absence of functional use. Study 3 examined the effects of relative group size when the classroom environment contained implicit messages about group status. In each study, children's intergroup attitudes (e.g., trait ratings, group evaluations) were assessed following several weeks in the classroom. The effect of relative group size on in-group bias was complex, varying as a function of (a) the relative size and salience of groups, (b) the measure used to assess intergroup attitudes, (c) group status (higher or lower), and (d) children's age.     

Factors contributing to the survival of self-help groups

Despite the growing utilization of self-help groups, there have been only a handful of studies that have examined the factors that contribute to their survival. The purpose of this study was to explore the factors that contribute to self-help group survival by examining their relationship with external sources (i.e., national and local self-help organizations, professionals) and group organizational characteristics (i.e., leadership diversification, recruitment, attendance at group meetings). Representatives from 245 active and 94 recently disbanded self-help groups were included in the analysis. Results indicated that the primary factors that discriminated between active and disbanded groups were the number of new people to attend a meeting, average group meeting attendance, length of existence, leadership diversification, outreach to potential group members, and support from national and local organizations. Results are discussed in terms of what national self-help organizations, self-help clearinghouses, and others who interact with self-help groups can do to empower and support them.     

Online group interaction and mental health: an analysis of three online discussion forums

The present study examined interactions on three Norwegian online discussion forums, and attempted to identify differences in interactions and plausible outcomes of thematically dissimilar forums. Four categories were applied to the forums in order to distinguish potentially constructive and destructive uses. Interaction along the constructive-destructive dimension was contingent upon the themes discussed, as well as the level and nature of professional involvement. Interaction adhering to a destructive dimension was identified only in relation to the forum for eating disorders. Discovering to what extent theme and professional involvement influence interactions in discussion forums might guide further professional involvement in online group settings and the design of appropriate online environments.     

Comprehension of reversible relative clauses in specifically language impaired and normally developing Greek children

This paper aims to investigate the syntactic comprehension of reversible relative clauses in a group of eight Greek children with specific language impairment (SLI) and two control groups of normally developing children matched on chronological and language age, respectively. An experiment using an acting out procedure was undertaken. Group analysis revealed that SLI children's performance is qualitatively different than that of both control groups. Interpreting the data, processes involved in syntactic comprehension are taken into consideration. It is claimed that processing demands impede SLI children's performance due to a deficit in their competence grammar.     

A controlled evaluation of group cognitive therapy in the treatment of irritable bowel syndrome

We randomized, at two sites, 210 patients with Rome II diagnosed irritable bowel syndrome (IBS), of at least moderate severity, to one of three conditions: group-based cognitive therapy (CT; n=120), psychoeducational support groups (n=46) as an active control, or intensive symptom and daily stress monitoring (n=44). One hundred eighty-eight participants completed the initial treatment. Those in symptom monitoring were then crossed over to CT. For an intent to treat analysis on a composite GI symptom measure derived from daily symptom diaries, both CT and the psychoeducational support groups were significantly more improved than those in the intensive symptom monitoring condition, but the CT and psychoeducational support group did not differ. Among treatment completers on the same composite measure of GI symptoms, again, both CT and psychoeducational support groups were statistically superior to symptom monitoring but did not differ on the symptom composite, or on any other measure. On individual IBS symptoms, both CT and psychoeducational support were statistically superior to symptom monitoring on reductions in abdominal pain and tenderness and for flatulence. Patient global ratings at the end of treatment showed the two active conditions statistically superior to symptom monitoring on change in Bowel Regularity, with CT superior to symptom monitoring on reduction in overall pain and in improvement in sense of well-being. Three-month follow-up data on 175 patients revealed maintenance of significant improvement or continued significant improvement on all IBS symptoms, including the McGill Pain Questionnaire. Group CT and psychoeducational support groups continued not to differ on any measure. We thus conclude that group CT is not superior to an attention placebo control condition.     

Learning from experience in case conference: A Bionian approach to teaching and consulting

In case conferences as well as didactic seminars, the power of the group can bring psychoanalytic education to life. However, primitive anxieties activated by group dynamics may also interfere with teaching and learning. The authors offer the example of a stalemated private practice case conference that had unconsciously organized against learning as the members began to read Bion's work. The case conference leader, an analyst, presented her case conference, which was mired in basic assumption dependency dynamics, to our peer consultation group. Drawing upon Bion's early contributions on groups, as well as his later ideas about thinking and mental growth, the peer group facilitated the case conference's return to work-group functioning and learning from experience. Activated in the peer group, commensal container↔contained processes gradually spread throughout the entire relational system of peer group, case-conference leader, case-conference members, and patients. This example underscores the importance of promoting within our institutes a culture in which faculty view themselves as part of an evolving intersubjective matrix that works to foster the containing capacities of candidates, patients, and faculty alike.     

Numerical representation and cross-cut role assignments: Majority members’ responses under cooperative interaction

This research investigates why cross-cutting role assignments, compared to those that converge, may worsen the intergroup attitudes of numerical majorities. Study 1 manipulated the numerical representation of groups and role assignments in a cooperative setting. As predicted, when the cross-cut role condition included the reintroduction of the numerical imbalance, the intergroup attitudes of majorities were more favorable than when the cross-cut condition did not reintroduce this discrepancy. Also, Study 1 showed that the intergroup attitudes of the majority were more positive when roles converged. Study 2 compared a convergent condition to one with converging roles that also reduced the salience of the majority’s numerical advantage. The results for this convergent-reduced-salience condition mimicked that of the cross-cut condition, revealing less positive majority attitudes. In both studies, results suggest that the processes of ingroup identification and relative ingroup homogeneity may mediate the effect of role assignments on ingroup bias. The findings are discussed in terms of the implications for cooperative interventions designed to improve intergroup attitudes.     

Relational semantics for full linear logic

Relational semantics, given by Kripke frames, play an essential role in the study of modal and intuitionistic logic. In [4] it is shown that the theory of relational semantics is also available in the more general setting of substructural logic, at least in an algebraic guise. Building on these ideas, in [5] a type of frames is described which generalise Kripke frames and provide semantics for substructural logics in a purely relational form.In this paper we study full linear logic from an algebraic point of view. The main additional hurdle is the exponential. We analyse this operation algebraically and use canonical extensions to obtain relational semantics. Thus, we extend the work in [4], [5] and use their approach to obtain relational semantics for full linear logic. Hereby we illustrate the strength of using canonical extension to retrieve relational semantics: it allows a modular and uniform treatment of additional operations and axioms.Traditionally, so-called phase semantics are used as models for (provability in) linear logic [8]. These have the drawback that, contrary to our approach, they do not allow a modular treatment of additional axioms. However, the two approaches are related, as we will explain.
