Redundancy: a similar principle in independent adaptation techniques

The present study examined the similarities between four auditory adaptation techniques to determine whether the effects were correlated. The four adaptation techniques compared were: Simultaneous Dichotic Loudness Balance technique (SDLB; Hood, 1950), Magnitude Estimated Binaural technique (MEB; Botté, Canévet, & Scharf, 1982), Magnitude Estimated Monaural technique, (MEM; Weiler, Sandman, & Pederson, 1981), and the Monaural Reaction Time technique (RT; Davis & Weiler, 1976). Results did not show significant correlations between the four techniques, except (r = 0.39) between MEB and MEM procedures. This correlation was much less than the reliability of the measures would allow (r = 0.98 and r = 0.99, respectively). Thus, it appears that the different methods either produced different adaptation effects or measured different aspects of auditory adaptation. The normal ear apparently shows several forms of adaptation, which reduces the perceptual strength of a continuing stimulus, in favor of an intermittent, less redundant one.     

Perceptual learning of a non-focal color discrimination between ages three and six

A match-to-sample task and a preference-ranking procedure were used to provide predifferentiation experiences on a color discrimination of 3-, 4-, 5-, and 6-year-old children. Chronological age was the best predictor of task success. Six-year-olds averaged twice as many correct matches as 3-year-olds. Gender and predifferentiation experience were not significant as main effects or in interactions affecting test performance. There was no difference between scores of untrained and trained children. The predifferentiation experiences had no effect. The data suggest that the years between 3 and 6 may be an important period in the development of the perceptual abilities needed to discriminate among subtle differences in one hue. Boys' and girls' abilities seem to develop at the same rate during this age span.     

Family Characteristics and Posttraumatic Stress Disorder: A Follow-Up of Israeli Combat Stress Reaction Casualties

This study assessed the role of family status and family relationships in the course of combat-related posttraumatic stress disorder (PTSD). The sample consisted of 382 Israeli soldiers who suffered a combat stress reaction episode during the 1982 Lebanon War. Results showed that one year after the war married soldiers had higher rates of PTSD than did unmarried soldiers. Furthermore, higher rates of PTSD were associated with low expressiveness, low cohesiveness, and high conflict in the casualties' families. Theoretical, methodological, and clinical implications are discussed.     

Chronic Illness and the Life Cycle:A Conceptual Framework

This article provides a conceptual framework for thinking about the system created at the interface of chronic illness with the family life cycle. First, a psychosocial typology and time phases of illness schema is described as a necessary, preliminary step to create a common language that bridges the worlds of illness, individual, and family development. This schema organizes similarities and differences between diseases in a manner useful to psychosocial-developmental rather than biomedical inquiry. Then, drawing on several major life-cycle theories in the literature, key concepts (periods of transition, life-structure building and maintaining, centripetality, and centrifugality) are used in a complementary fashion to link these three lines of development. Equipped with these psychosocial languages, consideration is given to transgenerational aspects of illness, loss, and crisis, and the interwoven threads of illness, family, and individual development. Clinical vignettes are provided to highlight this conceptual framework.     

Toward a generative theory of the therapeutic field

In the various models of family therapy, family systems are described as being patterned and programmed in their operations and development. The regularities and patterns found in family life are believed to be the expression of a program that determines the behavior of the family system and each of its members. Therapists holding this view will use "programming methods" in order to map family phenomena, and therapeutic work will consist of disrupting the problematic sequences in a deterministic way. However, if we take into consideration the impossibility of always linking inputs and outputs and the inability to evaluate consistently the behaviors in a system, problems associated with indeterminancy appear. Under such conditions, it may be impossible for therapists to formulate programs of family functioning. Therefore, we have operationalized a set of methodological principles that can be applied in such conditions. In this article we present the theoretical and practical implications for the field of therapy of "nonprogramming methods." A videotaped session is analyzed in order to show the application of the nonprogramming methods in clinical practice.     

Interventive Interviewing: Part I. Strategizing as a Fourth Guideline for the Therapist

A clinical interview affords far more opportunities to act therapeutically than most therapists realize. Because so many of these opportunities remain outside the therapist's conscious awareness, it is useful to elaborate guidelines that orient his or her general activity in directions that are liable to be therapeutic. The Milan associates defined three such basic guidelines: hypothesizing, circularity, and neutrality. Hypothesizing is clear and easy to accept. The notions of circularity and neutrality have aroused considerable interest but are not as readily understood. These guidelines may be clarified and operationalized when reformulated as conceptual postures. This process is enhanced by differentiating a fourth guideline, strategizing, which entails the therapist's decision making, including decisions about how to employ these postures. This paper, the first in a series of three, explores these four interviewing guidelines. The other papers will appear in a subsequent issue. Part II will focus on reflexive questioning, a mode of inquiry oriented toward mobilizing the family's own healing capacity. Part III will provide a scheme for analyzing and choosing among four major types of questions: linear questions, circular questions, reflexive questions, and strategic questions.     

Stability and Change in Type A Components and Cardiovascular Reactivity in Medical Students During Periods of Academic Stress1

This study examined the effects of academic stress upon components of Type A behavior and cardiovascular reactivity. In a longitudinal design, heart rate and blood pressure responses to the Type A Structured Interview (SI) and additional laboratory challenges were measured in medical students at three points during an academic semester. Sessions 1 and 3 were scheduled during vacation periods; Session 2 took place during an intensive examination week. Results indicated that three “stylistic” components of Pattern A derived from the SI—loud and explosive speech, short response latency, and potential for hostility—increased significantly during the exam period. Similar increases achieved marginal significance for another stylistic component, rapid and accelerated speech. By contrast, global Type A assessments did not increase with academic demands. Cardiovascular reactivity was significantly but only moderately stable across the three sessions, showing less consistency than has been reported in previous research. In addition, there was little evidence in this study that cardiovascular reactivity was potentiated by academic stress or by Type A behavior. These results demonstrate the influence of naturalistic environmental factors on overt behavioral components that have recently been suggested as coronary risk factors. Therefore, it is advisable for future experimental and epidemiological research to examine the social and environmental context in which these behaviors occur.     

The evolution of a therapy group for vietnam veterans on a general psychiatry unit

The evolution of a therapy group for hospitalized Vietnam veterans with post-traumatic stress disorder (PTSD) and related symptomatology is described. The literature on group treatment for this population is briefly reviewed and discussed in relation to an inpatient psychiatry setting. The prevailing conditions at the time of group inception are recalled along with the initial goals of the therapeutic intervention. Problems encountered are also discussed, along with the changes made in response to these identified difficulties. The results of three and one-half years of experience with this group are described in detail.The authors would like to thank Cynthia Sturm, Ph.D. for her helpful editorial assistance.     

Necessary factors in psychotherapy: A model for understanding iatrogenic disturbances

Psychotherapy is conceptualized within a phenomenoiogical framework as a relationship with a focus. Both these factors, the relationship and the focus, are examined as necessary factors for the creation of the therapeutic alliance which is seen as a sufficient condition for intrapsychic change. The proper balancing of the two necessary factors is seen as essential for a therapeutic alliance to evolve. The relationship factor is described in existential terms as a special form of the I-Thou encounter, while the focus factor is examined as part of the diagnostic aspect of psychotherapy. Iatrogenic distortions in psychotherapy are discussed in terms of distortions in the necessary factors-the focus and relationship. Four types of iatrogenic distortions are described: (1) overemphasis of the relationship and focus, (2) underemphasis of the relationship and focus, (3) overemphasis of the relationship and underemphasis of the focus and (4) underemphasis of the relationship and overemphasis of the focus.
