Clinical interventions in parent-infant groups around issues related to separation-individuation

Parent-child groups as an educational method in a general hospital setting provide support for parents and an environment in which they can discuss their questions about their child's development. This paper illustrates the clinical use of parent-child groups as a means of early intervention in problems that become apparent during the Separation-Individuation stages of development. We present two case studies of mother-child pairs, who have been members of the group for 2 years. The first case is a bi-racial child whose mother is struggling to deal with the child's rapprochement stage behavior. Through the oral and anal stages, conflict has grown in their relationship due to the mother's way of viewing her child, as well as her own unresolved adolescent separation difficulties. The second case is an overprotective mother whose own pathology prevented her daughter from resolving her rapprochement crisis. Interventions by the leaders as well as the group's educational method help both mother-child pairs to resolve interpersonal conflict and to continue their essentially normal development.     

Morphological errors in acquired dyslexia: A case of mistaken identity

Morphological errors in oral reading have been used to support theories of lexical access in which root morphemes and affixes are independently represented in the orthographic lexicon. No support for such theories was found in this study, which examined the morphological errors made by two patients with different patterns of acquired dyslexia. Instead, it was shown that the probability of making a morphological error depended upon the absolute levels of imageability and word frequency of the affixed word and the relative levels of its root morpheme. These properties also affected the oral reading of words without affixes. It was concluded that so-called “morphological” errors reflect the properties of the reading system which influence lexical orthographic access for both affixed and unaffixed words and further reflect the functional level of the lexical pathways available to the patient.     

Shared structure need not be shared set-structure

Recent semantic approaches to scientific structuralism, aiming to make precise the concept of shared structure between models, formally frame a model as a type of set-structure. This framework is then used to provide a semantic account of (a) the structure of a scientific theory, (b) the applicability of a mathematical theory to a physical theory, and (c) the structural realist’s appeal to the structural continuity between successive physical theories. In this paper, I challenge the idea that, to be so used, the concept of a model and so the concept of shared structure between models must be formally framed within a single unified framework, set-theoretic or other. I first investigate the Bourbaki-inspired assumption that structures are types of set-structured systems and next consider the extent to which this problematic assumption underpins both Suppes’ and recent semantic views of the structure of a scientific theory. I then use this investigation to show that, when it comes to using the concept of shared structure, there is no need to agree with French that “without a formal framework for explicating this concept of ‘structure-similarity’ it remains vague, just as Giere’s concept of similarity between models does ...” (French, 2000, Synthese, 125, pp. 103–120, p. 114). Neither concept is vague; either can be made precise by appealing to the concept of a morphism, but it is the context (and not any set-theoretic type) that determines the appropriate kind of morphism. I make use of French’s (1999, From physics to philosophy (pp. 187–207). Cambridge: Cambridge University Press) own example from the development of quantum theory to show that, for both Weyl and Wigner’s programmes, it was the context of considering the ‘relevant symmetries’ that determined that the appropriate kind of morphism was the one that preserved the shared Lie-group structure of both the theoretical and phenomenological models.

Self-generated attitude change: A person by situation analysis of attitude polarization and attenuation

The potential moderating effects of differences in the need for cognition on the attitude polarization process were explored. Based on putative schematabased differences in information processing, it was predicted that an increased opportunity for thought would result in (a) more attitude polarization for low need for cognition persons than for high need for cognition persons and (b) more attitude attenuation for high need for cognition persons than for low need for cognition persons. Participants completed the Need for Cognition scale and were given either little or ample time to think about issues toward which they previously held moderate attitudes. Attitudes were reassessed following thought about the issues. The results were consistent with the predicted moderating effects of individual differences in the need for cognition on thought-induced attitude polarization. Implications of and alternative explanations for the findings are discussed.     

Using group therapy to foster the psychosexual development of patients with eating disorders

When eating-disordered patients participate in long-term eating-dis-order groups, they move through phases of group development that parallel phases of psychosexual development. In the trust (oral) phase, members have an opportunity to experience a positive symbiosis, a suitable holding environment, and optimal frustration. In the control (anal) phase, members learn to identify and express anger constructively. In the intimacy (oedipal) phase, members learn to compete and be intimate. Individual and group movement is facilitated by the group leader being able to identify stages of group development and being able to utilize phase-related techniques.Many thanks to Anne Alonso, Ph.D., Robert Dies, Ph.D., and Geraldine Alpert, Ph.D., for their critiques of the first draft of this paper.     

Negative priming depends on prime-probe similarity: Evidence for episodic retrieval

It is well established that requiring a person to respond to a recently ignored object in a visual selection task leads to slower responding (i.e., negative priming). In the present experiment, subjects identified target letters flanked by incompatible distractor letters on prime and probe displays. Prime display distractors appeared as the target letter on one third of subsequent probe displays. We manipulated stimulus strength by means of intensity contrast between letter displays and their background. Displays were presented with either high contrast (white against a black background) or low contrast (dark gray against a black background). The important finding was that negative priming was maximal when prime and probe displays shared the same intensity contrast. These results suggest that greater similarity between prime and probe displays results in improved retrieval of prime display information. The results provide strong support for an episodic retrieval account of negative priming.     

Keeping a group psychotherapy program alive and well within a psychiatric residency

A mandatory year of outpatient group therapy training is an accepted part of residency training in psychiatry. Residents need stable groups to lead in order to have a satisfactory training experience. A solid group program is integrated and cohesive. A group therapy coordinator has to consider the following factors in developing and maintaining the optimum program: sanction from the department of psychiatry; integration of the program into the system; transfer of groups from one class to another; personal screening and followup of all referrals; availability to professionals in the community; coordinator participation in relevant group therapy classes; a vehicle for supervisors to collaborate with each other and administrator; and a format for all members of the group program community to interact.This paper is an elaboration of a symposium presentation, Training in Group Psychotherapy: The Quest for a Viable Model, AGPA Annual meeting, 1990.
