Human d-amphetamine drug discrimination: methamphetamine and hydromorphone.

Standard measures of subjective and discriminative effects of drugs were compared in 5 human volunteers. Subjects responded on a second-order color-tracking procedure, where 30 mg of d-amphetamine served as a discriminative stimulus for one response and its absence as the discriminative stimulus for another response. Self-reported subjective effects were assessed concurrently using the single-dose questionnaire, subscales of the Addiction Research Center Inventory, and several analogue rating scales. On different days following discrimination acquisition, varying doses of d-amphetamine, methamphetamine, and hydromorphone were administered. In these test sessions, either response was reinforced. Methamphetamine and d-amphetamine occasioned dose-related increases in d-amphetamine appropriate responding; hydromorphone did not. Methamphetamine and d-amphetamine occasioned dose-related increases in reports of the drug received being most like "speed"; hydromorphone occasioned dose-related increases in reports of the drug received being most like "dope." All three drugs occasioned dose-related increases in reports of drug liking, and increases in the morphine-benzedrine group, amphetamine, and benzedrine group scales of the Addiction Research Center Inventory. This experiment demonstrated that although explicit discriminative control of behavior by a drug may covary with drug identification, it does not necessarily covary with other self-reported subjective effects. Thus, the complementary nature of the data provided by drug discrimination and standard subjective-effects measures provides quantitative and qualitative data useful in studying both relatively novel compounds and the behavioral biology of psychoactive drugs in general.     

Temporal discrimination learning of operant feeding in goldfish (Carassius auratus)

Operant temporal discrimination learning was investigated in goldfish. In the first experiment, there was a fixed daily change in illumination. Eight subjects were trained to operate a lever that reinforced each press with food. The period during which responses were reinforced was then progressively reduced until it was 1 hr in every 24. The final 1-hr feeding schedule was maintained over 4 weeks. The feeding period commenced at the same time each day throughout. The food dispensers were then made inactive, and a period of extinction ensued for 6 days. The pattern of responding suggested that the fish were able to exhibit temporal discrimination in anticipation of feeding time. This pattern of responding persisted for a limited number of days during the extinction procedure. The second experiment produced evidence that operant temporal discrimination could develop under continuous illumination.     

Taking an individualized approach to the assessment of self-efficacy and the prediction of alcoholic relapse

The present study reports on a clinical instrument designed for assessing self-efficacy in alcoholics. In contrast to studies that construct general measures, it was proposed that taking an individualized approach to assessment might offer an effective methodology. Thirty-four alcoholics in an outpatient, behaviorally oriented treatment program participated as subjects. During therapy, an Individualized Self-Efficacy Survey (ISS) was developed for each subject. The ISS was developed by (a) administering the Drinking Patterns Questionnaire (DPQ) to identify important problem areas (e.g., work, children, marital) and specific drinking antecedents and (b) constructing a 15-item scale using each drinker's most important cues. The utility of having clients choose their own items was supported by finding a significant relationship between problem areas identified as important on the DPQ and the areas reported as surrounding relapse. ISS ratings were reflective of efficacy changes during treatment, while posttreatment ISS scores were predictive of subsequent relapse. Situation-specific prediction of relapse was not found. The advantages of this methodology for clinical use are discussed, while general directions for future research are suggested.     

Families and family therapy in Germany

The author describes some of the effects of decades of life under a dictatorship for East Germans and the effects on family life and family therapy of changes following the recent reunification of Germany. A case example illustrates some intergenerational family problems associated with the changes. Contrasts are drawn between East and West Germany and family therapy's present stage of development is depicted in both parts of the reunified country. Germany has approximately 10,000 trained family therapists, a minority of whom work in private practice. The largest amount of family and couples therapy is performed in agencies.Portions of this material were first presented in a poster session at the American Association for Marriage and Family Therapy annual conference in Miami Beach, 1992.     

The holocaust of first nation people: Residual effects on parenting and treatment implications

The residential school experience was devastating for many First Nation (Indian) people. The lingering effects of this era have been far reaching and remain painfully evident throughout Native communities. One of the more obvious areas directly affected has been parenting. This paper discusses current parenting difficulties of Native clients who were formerly in residential schools. A connection is made between the abuse experienced by these individuals and their parental struggles. Along with addressing various sociopolitical issues, a number of clinical interventions designed to promote the healing process of these victims and their families are provided and discussed.     

Health and behavior: The coming together of science and practice in psychology and medicine after a century of benign neglect

For thousands of years, physicians had available only a few drugs with which to minister to patients and the practice of psychology was an integral and therapeutically powerful component in the practice of medicine. Thus, good bedside medicine consisting of empathy, compassion, and a nurturant attitude toward the ill individual was a major component of the physician's armamentarium until relatively recently. However, the explosion in scientific knowledge in biology, physiology, chemistry, and microbiology which began a century ago and has continued through the twentieth century helped produce several generations of physician specialists and subspecialists with little knowledge of the powerful role psychological factors play in health and illness. As a result, practitioners of medicine and practitioners of psychology have had little or no contact during most of this century. However, as advances in microbiology, public health, and nutrition have eradicated many of the infectious diseases, infirmities associated with one's lifestyle have replaced the latter as the major causes of death today. One offshoot of this shift is that after a century of benign neglect, physicians and psychologists have rediscovered a common ground in the arena labeled health and behavior. Some factors responsible for these recent developments are highlighted.This article was an invited address delivered to a group of Japanese health psychologists as part of a Health Sciences Seminar in Tokyo on July 24, 1993.
