The conceptual structure of aphasic and schizophrenic patients in a nonverbal sorting task

Hierarchical and overlapping cluster methods were applied to the sortings of aphasic, nonaphasic brain-damaged, schizophrenic, and normal subjects presented with 30 pictures of animals. The hierarchical structure solutions were most diffuse for the groups of the schizophrenics and the fluent aphasics. The structure for the nonfluent aphasics showed more clarity, but was also deviant from the structures of the normals and the brain-damaged without aphasia. Fluent aphasics but not nonfluent aphasics tended to sort pictures which they could not name into smaller groups. For the nonfluent aphasics, there was a significant correlation between the commonality of the sortings and the severity of aphasic disturbances as measured by the Token Test. The relationship between conceptual disorganization and language impairment seems to be functionally different for fluent and nonfluent aphasics.This research was supported by a research grant from the Deutsche Forschungsgemeinschaft.     

Affective modulation of recognition bias

A correspondence of processing on the familiarity-novelty and positive-negative dimensions, particularly in the earliest processing stages, is proposed. Familiarity manipulations should, therefore, not only influence affective evaluations (e.g., the mere exposure effect), but affective manipulations should also bias familiarity judgments (e.g., in recognition). In Experiment 1, both previously presented and new recognition test words were primed by matching, nonmatching, positive, or negative context words. In Experiment 2, more diffuse affective states were induced during recognition test trials by contracting facial muscles that corresponded to positive and negative expressions. Particularly when participants were less aware of the familiarity and affective manipulations, corresponding effects were found. Positive affect led to a more liberal recognition bias, and negative affect led to more cautious tendencies.     

Perceived stress,life events,dysfunctional attitudes,and depression in adolescent psychiatric inpatients

Hewitt, Flett, and Mosher (1992) examined the factor structure of the Perceived Stress Scale (PSS) and its relation to depression in adult psychiatric patients. This study sought to replicate and extend their findings, using a sample of 203 adolescent psychiatric inpatients. All patients admitted to the adolescent unit in a psychiatric hospital over a 3-year period were administered the PSS, as well as measures of depression, life events, dysfunctional attitudes, and intellectual abilities. Consistent with Hewittet al., two factors were found in the PSS, reflecting perceived distress and perceived coping ability. Regression analyses indicated that, for males, both factors account for independent variance in depression, whereas for females, only the distress factor is related to depression. In addition, for both male and female, dysfunctional attitudes account for significant variance in depression in addition to PSS, but negative life events do not. None of the variables were related to intellectual abilities. Implications for clinical assessment and intervention are discussed.     

Learning climate scale: Construction,reliability and initial validity evidence

The current study developed an instrument for measuring learning climate in organizations. A review of the organizational learning and facilitation of workplace learning literature resulted in three theoretically relevant dimensions referring to facilitation, appreciation, and error avoidance. The 3-dimensional learning climate scale (LCS) was tested in a heterogeneous sample of Dutch wage earners (N = 1013). Confirmatory factor analysis and analysis of measurement invariance were conducted to establish the factorial structure of the measure. Also, convergent, divergent, and construct validity of the LCS were investigated. The findings showed that the newly developed instrument for learning climate has good psychometric properties: the three-factor structure was supported and the sub-scales were reliable. Furthermore, the LCS showed good convergent and divergent validity.     

Play,Dreams and Imitation in Childhood by Jean Piaget

Variously described as enhancing sentience, supporting professional identity, providing insight and introducing the resident to covert group processes, the experiential group has been a part of residency education for over 25 years. This article specifically focuses on and identifies the potential areas for learning about group process in such an experience. These areas are organized around the contribution of individual psychological, social-psychological, and group-as-a-whole issues in the group. Actualization of the learning depends on the psychological state and level of emotional preparedness of the individual member, the consultant's orientation and style, the composition and development of the group, and its relationship to the organization in which it takes place. An example is provided to highlight the areas of potential learning, and there is a discussion of some applications to the patient role and the practice of group psychotherapy.     

Bounded Revision: Two-Dimensional Belief Change Between Conservative and Moderate Revision

This paper presents the model of ‘bounded revision’ that is based on two-dimensional revision functions taking as arguments pairs consisting of an input sentence and a reference sentence. The key idea is that the input sentence is accepted as far as (and just a little further than) the reference sentence is ‘cotenable’ with it. Bounded revision satisfies the AGM axioms as well as the Same Beliefs Condition (SBC) saying that the set of beliefs accepted after the revision does not depend on the reference sentence (although the posterior belief state does depend on it). Bounded revision satisfies the Darwiche–Pearl (DP) axioms for iterated belief change. If the reference sentence is fixed to be a tautology or a contradiction, two well-known one-dimensional revision operations result. Bounded revision thus naturally fills the space between conservative revision (also known as natural revision) and moderate revision (also known as lexicographic revision). I compare this approach to the two-dimensional model of ‘revision by comparison’ investigated by Fermé and Rott (Artif Intell 157:5–47, 2004) that satisfies neither the SBC nor the DP axioms. I conclude that two-dimensional revision operations add substantially to the expressive power of qualitative approaches that do not make use of numbers as measures of degrees of belief.     

A Negotiation Approach to Intake and Treatment Choice

Treatment choice is the decision process whereby the psychotherapeutic methods and the psychotherapist are determined when psychotherapy is recommended for a specific client. In this article the problem of treatment choice is situated within an integrative view of psychotherapy. A review of the literature confirms the usefulness of the following concepts for treatment choice: client preferences, client control of the situation of choice, and the mutual acceptability of differing views of therapists and clients. These research findings reveal the importance of four elements in the psychotherapeutic intake strategy: exploration of the client's perspective, informing the client, negotiation as a process of confrontation between the client's and the clinician's perspective, and the client's ultimate choice between alternative treatment proposals.     

The legal basis for the Danish committee on scientific dishonesty

The author, a High Court Judge, has chaired the Danish Committee on Scientific Dishonesty (DCSD) since its establishment in 1992. The Committee has worked in the health sector, but from 1999 the scope has been broadened to cover all fields of science. The article describes how the work is organised and the experiences gained. It is stressed, that the difficulty in connection with scientific dishonesty is, first and foremost, to organise a system suitable for investigating cases effectively, professionally, and with proper respect to the fundamental legal rights of the parties involved. The Committee has also spent much effort in determining what can be termed scientific dishonesty and what falls outside this category but which may, nevertheless, be characterised as breaching of good scientific practice. It is emphasised that these rules are not arbitrarily established by the Committee, but formulated in accordance with norms general accepted by opinion leaders in the scientific community. An carlier version of this paper was presented at a symposium, Scientific Misconduct. An International Perspective, organised by The Medical University of Warsaw, 16 November, 1998. The article is based on more comprehensive articles by the same author in DCSD’s Annual Reports for 1993 and 1995.
