TOWARD A FUNCTIONAL ANALYSIS OF SELF-INJURY

This study describes the use of an operant methodology to assess functional relationships between self-injury and specific environmental events. The self-injurious behaviors of nine developmentally disabled subjects were observed during periods of brief, repeated exposure to a series of analogue conditions. Each condition differed along one or more of the following dimensions: (1) play materials (present vs absent), (2) experimenter demands (high vs low), and (3) social attention (absent vs noncontingent vs contingent). Results showed a great deal of both between and within-subject variability. However, in six of the nine subjects, higher levels of self-injury were consistently associated with a specific stimulus condition, suggesting that within-subject variability was a function of distinct features of the social and/or physical environment. These data are discussed in light of previously suggested hypotheses for the motivation of self-injury, with particular emphasis on their implications for the selection of suitable treatments.     

REEMERGENCE AND EXTINCTION OF SELF-INJURIOUS ESCAPE BEHAVIOR DURING STIMULUS (INSTRUCTIONAL) FADING

Based on results of a functional analysis indicating that the self-injurious behavior (SIB) of 3 individuals was maintained by negative reinforcement (escape from instructional situations), the effects of stimulus (instructional) fading were evaluated in a multiple baseline design across subjects. The rate of instructions was reduced to zero at the beginning of treatment and was gradually increased (faded in) across sessions as long as SIB remained low. However, if SIB remained high for 10 consecutive sessions, extinction was implemented until SIB decreased, at which point extinction was withdrawn and fading was resumed. Treatment was completed when the rate of instructions was the same as in baseline (two per minute), and SIB remained below 0.5 responses per minute for two consecutive sessions. Results showed that instructional fading (without extinction) virtually eliminated SIB initially, but these effects were not maintained. All 3 subjects required multiple exposures to extinction and over 150 treatment sessions in order to meet the end-of-treatment criteria. Advantages and limitations of fading procedures without an extinction component, as well as extensions of both interventions to other clinical problems, are discussed.     

Modal logics with the Macintosh rule

Conclusion Having gained some idea of what MacIntosh logics there are, we conclude this paper with a remark about the totality of them. Let theterritory of a rule or condition be the class of all modal logics that have the rule or satisfy the condition. What is MacIntosh territory, the class of all normal logics with the MacIntosh rule, like? What is its structure?We are especially indebted to Max Cresswell, Rob Goldblatt, Steve Kuhn, Jack MacIntosh, Tamara Ollenberg, and Tim Williamson for very helpful contributions along the way to the present version of this essay. Elements of it were presented by Chellas at a miniconference on Issues in Philosophical and Mathematical Logic, in Devonport, New Zealand, 11–12 May 1991, at a South West Logic Workshop in Seattle, Washington, 20 July 1991, and at a meeting of the Florida Philosophical Association in Boca Raton, Florida, 8 November 1991. We wish to thank all who offered comments at those gatherings. An earlier version of the paper appeared in the Auckland Philosophy Papers series of the Department of Philosophy, University of Auckland, in May 1991.     

Structural family therapy with Mexican-American family systems

Characteristics of traditional Mexican-American families with consequent family rules that affect these family systems are discussed along with selected clinical cases. The specific cases discussed involve: (1) interactions with family of origin in intercultural marriages, (2) intracultural differences in levels of acculturation and traditional family rules, and (3) extended family impact in response to severe life crisis. The development of therapeutic processes from structural and strategic family therapy approaches, which reflect appreciation for cultural differences and strengths, is suggested.This material was presented at the annual meeting of the Texas Association for Marriage and Family Therapy, January, 1994, San Antonio, TX.     

Shattering the illusion of control: Multi-shot versus single-shot gambles

The illusion of control refers to a phenomenon whereby people believe their chances of success at a task are greater than would be warranted by objective analysis. This article raises two questions. First, how robust is the illusion of control? Second, how might the illusion be ‘shattered?’ Previous experimental demonstrations involved situations that can be likened to unique or single-shot gambles. If, however, the phenomenon is robust, it should occur in repeated or multi-shot gambles in which the outcome depends on a series of gambles involving the same underlying random process. It should also appear in single-shot gambles that are framed so as to superficially resemble multi-shot gambles. We label this the strong illusion of control hypothesis. On the other hand, because people have a better appreciation of probabilistic concepts in tasks they are able to represent as relative frequencies, the introduction of a multi-shot or ‘pseudo-multi-shot’ context might cue people to the random nature of the task, thereby shattering the illusion. The weak illusion of control hypothesis holds that the illusion of control will occur in single-shot but not in multi-shot or pseudo-multi-shot gambles. Two studies are reported that support the weak hypothesis. Alternative explanations are considered and implications are discussed.     

Training the supervisor: Integrating a family of origin approach

The replication of intergenerational patterns is considered here within the supervisor-family therapist-and family system, and the proposal of integrating a family of origin approach into the training of supervisors is presented. To become aware of the relation of one's own family of origin issues and their potential impact within the supervision and treatment can effectively improve intervention approaches, benefitting the supervisor, the therapist and the family in treatment. Being considerate of the training needs and levels of supervisors is an important component when integrating family of origin work into the training.     

“Operationalism” in psychotherapy: A possible means of putting a sorry state of theory in better order?

It will be shown in this paper that the study of the actual conduct of psychotherapy, at least in its classical form with a patient speaking his or her mind in any way the patient desires and a therapist helping the patient pursue those thoughts and wishes and conflicts and hopes for better luck in real life than before, is more conducive to agreement among rather different therapists, to clearer reasoning over psychotherapeutic interventions, and to more promising theoretical articulations than anything available in the theoretical texts of psychotherapy.     

The relation of family cohesion to marital adjustment

The purpose of this study was to investigate the relationship between family cohesion and marital adjustment. The sample consisted of 70 married graduate students from the State University of New York at Buffalo. The Family Adaptability and Cohesion Evaluation Scale was used to measure family cohesion. The Dyadic Adjustment Scale was used to measure marital adjustment. The Demographic Data Sheet was used for demographic characteristics. Overall, the result of ANOVA with planned comparison revealed that high marital adjustment was not only associated with a moderate level of family cohesion but also associated with a high level of family cohesion.This article is based on the first author's doctoral dissertation at State University of New York at Buffalo.     

Prism adaptation while tracking and saccading

It is known that positional discordance between the spatial senses is a sufficient condition for prism adaptation of registered eye-in-head position. In this experiment adaptation was carried out under conditions in which Ss viewed their feet while making extensive tracking or saccading movements of their eyes. It has been claimed that tracking makes available less precise position information than saccading (Festinger and Canon 1965), but it is found that both modes are equally successful in causing this form of adaptation. It is concluded that either tracking and saccading yield equally valid estimates of eye-in-head position, or that the normal straight ahead position of the eye is a unique reference position.
