Toward a theory of hypnotic behavior: Effects on suggestibility of defining the situation as hypnosis and defining response to suggestions as easy.

96 Ss participated in a 2 X 2 factorial experiment which was designed to assess the effects on suggestibility of: defining the situation as hypnosis or as control, and defining response to suggestions as easy or as difficult. The dependent variables consisted of responses to 8 standardized test suggestions (Barber Suggestibility Scale). Ss told "You are in the hypnosis group" were more responsive to suggestions than Ss told "You are in the control group." Ss told that it was easy to respond to test suggestions were more suggestible than Ss told that it was difficult. The suggestibility-enhancing effects of the independent variables were additive: the level of suggestibility was highest when the situation was defined as hypnosis and the test suggestions as easy; next highest when either the situation was defined as hypnosis or the suggestions as easy; and lowest when the situation was defined as control and the suggestions as difficult.

The role of the psychologist in the disability evaluation of emotional and intellectual impairments under the social security act.

"Psychological examinations are frequently required for the evaluation of emotional and intellectual impairments in order to establish the degree of loss of function in workers who apply for disability benefits as well as in adults who are disabled in childhood… . The presence of severe and persistent illness should be associated with objective evidences of regression substantial enough to preclude vocational activity… . Psychological evaluations serve to pinpoint the specific functional capacities of the applicant so as to serve as a basis for the evaluation as well as for rehabilitation."

Bully Busters abbreviated: Evaluation of a group-based bully intervention and prevention program.

The present study sought to examine the efficacy of an abbreviated version of the Bully Busters program, a psychoeducationally based group intervention and prevention program designed to increase teacher's knowledge and use of bullying intervention skills, as well as teacher self-efficacy in intervening with bullying so as to subsequently effect change in the school climate. Teacher-participants attended seven group sessions designed to provide them with exposure to the didactics of the model, as well as to engage them in active learning, role-playing, and cognitive and emotional processing of their experiences of the impact of bullying behaviors on their teaching efficacy as well as the school climate. Materials and experiences from these groups were then taken to the classroom and implemented with the student-participants vis-à-vis classroom exercises. The findings suggest that an abbreviated group-based version of the Bully Busters program can have positive effect on teacher reports of efficacy in intervening with bullying behaviors.

Freud's relevance for contemporary psychoanalytic technique.

It is argued that Freud's influence on contemporary technique is best seen by separating Freud as a hermeneuticist from Freud as a natural scientist. Freud's hermeneutic work is elucidated by a depiction of his earliest model of technique and its application in The Interpretation of Dreams. The division of the latter work into the first 6 chapters as a hermeneutic and the last chapter as a metapsychology is used to show not only the split but the conflict in Freud between his hermeneutic of the mind and his attempt to found psychoanalysis as a natural science. It is shown that the shift in analytic thinking from the primacy of drives to the growth and transformation of the self has maintained interpretation as a necessary, although insufficient, condition for the therapeutic action of psychoanalysis and that interpretation continues to bear the stamp of Freud's hermeneutic of the mind.

Review of Brief psychotherapies: Principles and practices.

Reviews the book, Brief psychotherapies: Principles and practices by Michael F. Hoyt (2009). Despite the evident desire of many clients to address their issues in as time-efficient manner as possible (even one session), most therapists are trained to deliver psychotherapy via longer-term models of practice. Although more graduate programs than in the past are beginning to offer training in brief therapy, in many instances this is a one course elective without related practical experience. Hoyt’s book provides a wide-angle overview of the field of brief therapy, as well as an up close look at one of its most prominent models (Solution-Focused Therapy). In doing so, it could serve as a centerpiece for courses in brief psychotherapy. Time sensitive therapy fits in a time sensitive world—a world in which both the clients and funders of services want problems to be addressed in as focused a way as possible. This book teaches therapists a great deal about how to navigate in that world. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
