Effects of absolute mask energy and mask energy range on metacontrast suppression

In an experiment similar to one by Bernstein, Fisicaro, and Fox (1976), subjects were asked to judge the brightness of test stimuli in a metacontrast display. The energies of the test and of the mask varied orthogonally. Various experimental conditions differed with respect to the range of mask energies. Individually, the mask energies were generally weaker than the test energies. The results replicated the main findings of Bernstein et al. (1976) in that judgments of the test were negatively correlated with mask energy at short stimulus onset asynchrony (SOA) but positively correlated at long SOA. These effects were more pronounced when the masks were similar in energy range and level to the tests than when they were wider in energy range and weaker. In general, there was no evidence for the effects of trial-to-trial variation described by Hake, Faust, McIntyre, and Murray     

The word superiority effect: Dependence on short-term memory factors

Two experiments were conducted to test whether the word superiority effect, that letters in words are perceived more accurately than letters in nonwords, could be attributed to short-term memory (STM) factors. One hypothesis attributed the word superiority effect to superior maintenance of words in STM. Another hypothesis was that letters in STM have considerable positional uncertainty which is overcome by the orthographic characteristics of the words. Both experiments utilized a simultaneous same-different task, where subjects compared two four-letter strings, one on top of the other, which were presented tachistoscopically. In Experiment I, the two presented strings were either both words or both nonwords and a word superiority effect was obtained. This result was interpreted as disconfirming the STM maintenance hypothesis. In Experiment II, letters were removed from one of the two letter strings, making the serial position of the comparison unambiguous. The word superiority effect disappeared. This result was interpreted as supporting the positional uncertainty hypothesis.     

Beating the memory drum: Rapid sequential visual presentation (RSVP) on a 4K PDP-8

A program for presenting alphanumeric strings in rapid succession on a Videoterminal is described. Rates of up to 30 items/sec can be obtained with relatively “slow” systems by creating a push-up stack in the terminal’s display memory and scrolling the items past a small display window during presentation. Advantages of such a program are discussed, and the system is compared to mechanical techniques of rapid sequential visual presentation.     

ABSTRACTS OF LITERATURE

This paper describes the family dynamics of the identified patient with manic-depressive illness. Method included chart review of 53 families in which the identified patient had bipolar, manic-depressive illness; of these 57, 43 were married. Of these 43, eight participated in two, sequential, post-hospital, psychotherapy groups. Clinical observations noted were: (a) the threat of recurring mania, (b) hostility between spouses, (c) massive denial, (d) symbiosis and dependency, (e) weak or absent father. Therapy implications were discussed.     

ABSTRACTS OF LITERATURE

This theoretical essay offers a critique of individual psychotherapy versus the advantages of family therapy. Theories of family pathology, models, techniques, and indications, are reviewed and the relationship of family therapy to behavior therapy, multiple-impact therapy, home visits, crisis therapy, network therapy, and multiple-family group therapy are discussed.     

ABSTRACTS OF LITERATURE

Fifteen are described and compared, training programs for family therapists, using a scale published by the Group for the Advancement of Psychiatry that identifies the theoretical spectrum of each of the centers. Results indicate that the centers vary from experiential to structural (with a few in the middle that combine both orientations). It was concluded that training programs as they now exist suffer from the absence of an adequate diagnostic nomenclature for family therapy and from an insufficiently designed conceptual framework.     

Maintaining disulfiram ingestion among outpatient alcoholics: a security-deposit contingency contracting procedure

Disulfiram is frequently prescribed to alcoholic patients as a deterrent to drinking. Although ingestion of ethanol by a disulfiram patient quickly results in an intense dysphonc reaction, the drug is not generally credited with significant value in alcoholism treatment (Mottin, 1973). It is suggested that most alcoholics simply stop taking the medication (Gerrein et al., 1973). and review articles conclude that motivation for abstinence is the crucial variable involved in successful disulfiram treatment (Ditman, 1966: Mottin, 1973).Motivation may be a characteristic of environmental contingencies rather than of individuals. If so, environmental contingencies should permit one to design into a disulfiram treatment progrim the requisite motivation to achieve therapeutic success. Contingency management procedures supporting disulfiram ingestion reported to date (Liebson et al., 1973: Haynes, 1973) have been of the sort to be imposed upon difficult populations rather than offered to general treatment applicants. Contingency contracting may represent a technique for supporting disulfiram ingestion appropriate to the broader general population of voluntary alcoholism treatment applicants. Contingency contract treatment (Homme, 1969; Stuart, 1971) is a procedure in which client and therapist mutually agree to establish an incentive for the client to achieve a behavioral goal. Contingency contracts can be viewed as a form of self-control therapy, and have been applied in a wide variety of problem areas, including school problems (Homme, 1969: Cantrell, et al., 1969). delinquency (Stuart, 1971),weight control (Mann, 1972). smoking reduction (Elliott and Tighe, 1968: Winett, 1973), drug abuse (Boudin, 1972), and alcoholism (Miller, 1972).Frequently contingency contracting involves the client's posting of a financial security deposit to serve as his incentive for achieving the agreed-upon therapeutic goal (Tighe and Elliot, 1968). This security deposit can be earned back consequent upon achieving specific goals, or sacrificed consequent upon failure. Controlled studies by Mann (1972) and by Winett (1973) have demonstrated this security-deposit procedure to be effective in enhancing weight loss and smoking reduction, respectively.We report here on our experience with application of the security deposit contracting procedure to maintaining routine disulfiram ingestion among outpatients in an alcoholism treatment program.     

ABSTRACTS OF LITERATURE

A discussion of family therapy emphasizing the indications for and the goals of this type of treatment. Differences between family and group therapy are presented with the suggestion that group treatments exists for individual improvement and growth and family treatment for improvement of relationships and growth of the family unit.     

Psychojargon in the psycholegal report: Ratings by judges,psychiatrists, and psychologists

Questionnaires designed to measure the perceived value of technical terminology for psycholegal reports were completed by 67 judges, 78 forensic psychiatrists, and 126 forensic psychologists. Judges were asked for ratings of the degree to which each term aids their understanding, and clinicians were asked for ratings of the likelihood that they would use each term in a report for the court. Rank-ordered ratings of the 45 terms were highly correlated among the three respondent groups, suggesting that forensic clinicians are generally aware of the problem of using incomprehensible psychojargon. Empirical ratings can be helpful in distinguishing between comprehensible and incomprehensible psychojargon for psycholegal use.     

Development and validation of the Illness Behavior Inventory

The development and validation of a measure of illness behavior are presented. From a large domain sample of illness-related behaviors, a 20-item self-report measure was developed, the Illness Behavior Inventory (IBI). Validation data are presented from a series of independent studies with healthy and chronically ill individuals. Results indicate that the IBI possesses acceptable levels of internal consistency, test-retest reliability, structural reliability, discriminant validity, concurrent validity, and predictive validity. The applicability of the IBI to various areas of inquiry in behavioral medicine research and practice is discussed and directions for future research are outlined.
