Skin conductance,reaction time,and observational ratings in learning-disabled children

Rates of GSR habituation, reactiontime responses, and observational ratings in normal and learningdisabled children were evaluated. Compared to normals, children with learning disabilities demonstrated faster rates of GSR habituation in a task involving active attention, slower reactiontime responses, and more characteristics of “minimal brain dysfunction” on a rating scale. Within the learningdisability group those subjects with a family history of reading problems showed fewer GSR, reactiontime, and rating responses characteristic of “minimal brain dysfunction.”     

Seeds of discontent: Expert opinion, mass media messages, and the public image of agricultural biotechnology

Survey data are presented on opinions about agricultural biotechnology and its applications held by agricultural science faculty at highly ranked programs in the United States with and without personal involvement in biotechnology-oriented research. Respondents believed biotech holds much promise, but policy positions vary. These results underscore the relationship between opinion and stakeholder interests in this research, even among scientific experts. Media accounts are often seen as causes, rather than artifacts, of the existence of public controversy; European and now U.S. opposition to food biotechnology is often explained away in terms of such a relationship. The authors argue that where even experts are divided, public opposition cannot reasonably be attributed to poor public understanding or sensationalistic media accounts. Ethical implications for communicating science are explored.     

A prospective study of the distribution of illness within the menstrual cycle

The cyclic physiological variations during the menstrual cycle are thought to be associated with change in emotional state, in susceptibility to illness, and in frequency of illness-related behavior. Variations in frequency of illness with the phases of the menstrual cycle were examined using data from a 3-year prospective study of social and psychological antecedents of viral illness in 94 student nurses. Reported illnesses, accidents, medical consultations, and hospital admissions were randomly distributed throughout the menstrual cycle. Subjects took more medication on the 1st day of menses than on any other day of the cycle; howeverreported menstrual symptoms were infrequent, with only 4% of the population reporting two or more such episodes. It was concluded that there was an increase in discomfort on the data of onset of menses which was self-medicated but not defined as illness. There was no discernible relationship of illness or disability to any phase of the cycle.This work was supported in part by Center for Oral Health Research (COHR) grant DEO 2116, and Oral Medicine Training Grant ST01-DE-77. The authors wish to recognize the contribution of Carol Ram, R. N., who was the administrator of this study and responsible for the collection and organization of the large bank of information from which the material for this paper was abstracted. Without her care, diligence, and intelligent management, this study could not have been completed. We also wish to acknowledge the consultive advice of Dr. Larry Laster, Director, Division of Biometrics, School of Dental Medicine, in choice of analytic techniques, and the help of Dr. Arthur Segal in the early stages of data analysis.     

To be and not to be: Dialectical tense logic

The paper concerns time, change and contradiction, and is in three parts. The first is an analysis of the problem of the instant of change. It is argued that some changes are such that at the instant of change the system is in both the prior and the posterior state. In particular there are some changes from p being true to p being true where a contradiction is realized. The second part of the paper specifies a formal logic which accommodates this possibility. It is a tense logic based on an underlying paraconsistent prepositional logic, the logic of paradox. (See the author's article of the same name Journal of Philosophical Logic 8 (1979).) Soundness and completeness are established, the latter by the canonical model construction, and extensions of the basic system briefly considered. The final part of the paper discusses Leibniz's principle of continuity: Whatever holds up to the limit holds at the limit. It argues that in the context of physical changes this is a very plausible principle. When it is built into the logic of the previous part, it allows a rigorous proof that change entails contradictions. Finally the relation of this to remarks on dialectics by Hegel and Engels is briefly discussed.     

Insight-oriented group psychotherapy of latency-age children in an acute care setting

Traditional approaches to group therapy with latency-age children have stressed activity and nonverbal therapeutic interventions. These approaches originated in the 1940s with Slavson's activity aroup therapy. A review of the literature of the past 25 years reveals that many clinicians have increasingly employed verbal techniques with latencyage groups. Most such reports describe groups for latency-age out-patients. In this paper, a verbal, interpretive technique for group therapy with latency-age inpatients is described. Clinical vignettes are included to illustrate this technique. Our experience suggests that such a technique can become an integral part of the inpatient treatment program for the latency-age child.     

Theories of family pathology: In what direction

Although specific typologies, classifications, or taxonomies of family pathology have been demonstrated to have research merit, it is clear that their practical or clinical application has been at best marginal. The general theories in family therapy have not yet led to the development of viable typologies.I believe there are three general theories which perhaps converge only in their acceptance of a process of victimization in families that may lead to the outbreak of psychiatric symptoms in members: the intergenerational, the communicational, and scapegoat theory. The paper describes these theories and suggests their strengths and limitations. The dominant family therapies that have arisen in the late 1970s are short-term approaches. These are especially favorable to the development of scapegoat theory, fit reasonably well with communicational theory, but are inconsistent with intergenerational theory.An invited lecture at the 11th International Congress of Psychotherapy in Amsterdam, August 28, 1979.     

Early declarative memory for location

The abilities of 7.5-month-old infants to recall the location of hidden objects after delays averaging 90 seconds were investigated in three experiments. Various kinds of events were introduced during the delays in order to examine the stability of early location memory. Recall, as shown by reaching towards the correct location, was most clearly found when the infants were allowed either to remain seated facing the hiding locations (Expt 1) or were turned around and immediately re-seated (Expt 2) during the delays. In both experiments, the infants’ attention was diverted from the hiding places, but during all or most of the delay the infants were facing the locations. Recall was dampened when infants were removed from the immediate location of the hiding and engaged in other activities such as looking at a picture during the delay (Expt 3). Further analyses indicated an effect for age that coincides with other research on location memory: evidence for recall was more clearly found for the older, but not the younger, 7-month-olds.
