MCMI characteristics of DSM-III posttraumatic stress disorder in Vietnam veterans

Compared the MCMI profiles of 25 veterans with a diagnosis of Posttraumatic Stress Disorder (PTSD) with those of 25 veterans carrying psychiatric disorders which typically cause problems in the differential diagnosis of PTSD. The PTSD group had higher elevations on nine of the 20 MCMI scales (all ps less than .05). Profiles were also significantly different in shape and scatter. A discriminant analysis accounted for 100% of the variance and correctly classified 88% of the patients. Resulting MCMI profiles appear to be consistent with DSM-III criteria for PTSD.     

Focal changes in cerebral blood flow produced by monetary incentive during a mental mathematics task in normal and depressed subjects

The purpose of this experiment was to determine the effect of incentive-induced arousal on the diffuse and regional cerebral blood flow (rCBF) response during cognitive activation for normal and depressed groups. Two normal rest CBF measurements were followed by two mental mathematics activation CBF measurements. For the first activation measurement, half the subjects in each group were offered monetary incentive for correct performance and half the subjects received no monetary incentive. All subjects were offered monetary incentive on the final activation run. The effect of monetary incentive on the first activation run was to increase CBF activation at four detectors in the left hemisphere. Incentive did not affect the CBF activation response when introduced following practice on the activation task (on the final run). Depressed groups had lower resting blood flow than normals, but the distribution of flow and the CBF response to incentive were almost identical in the two groups.     

Category similarity effects in children's semantic memory retrieval

Fourth-, sixth-, and eighth-grade students were required to indicate whether or not a stimulus word belonged in either of two semantic categories that were held in memory. Each category pair was either semantically similar or semantically dissimilar. The results indicated that even for the youngest children, similar categories required less search time than dissimilar categories. It was suggested that while dissimilar categories had to be accessed successively prior to search, subjects were able to consolidate similar categories into a superordinate group which eliminated the time to shift from one category to another during search. The results were contrasted with clustering studies which have demonstrated a minimal amount of memory facilitation in children for conceptually related items over unrelated items.     

An Institution for Change: Developing a Family Day Unit

This paper describes the theory and structure of a day unit designed to intervene in the systems of families who present with severe or multiple problems to agencies attempting to help them, but who are difficult to engage in a therapeutic pact and unresponsive to attempts at outpatient therapy. An analysis of these families is offered in terms of the relations between internal and external boundaries and difficulties in making transitions in the daily contexts of life. The principles of the unit are described in terms of the creation of an artificial extended family, the intensification of sequence and patterns of interaction, and the making and traversing of boundaries. Particular attention is paid to the function of agency interventions in family patterns and to redefining the relationship between family and agencies.     

Developmental aspects of the generation effect

Children from Grades 2, 3, 5, and 7 (7.6, 9, 11, and 13 years of age, respectively) were required to generate or study exemplars of semantic categories (semantic orientation) or rhymes to stimulus words (phonetic orientation). Each child then participated in one of three retention tests: free recall, standard recognition, and rhyme recognition. The results indicated that the developmental emergence of the “generation effect” (C. E. McFarland, Jr., T. J. Frey, & D. D. Rhodes, Journal of Verbal Learning and Verbal Behavior, 1980, 19, 210–225; N. J. Slamecka & P. Graf, Journal of Experimental Psychology: Human Learning and Memory, 1978, 4, 592–604) was dependent on both encoding orientation and the type of retention task employed. A substantial generation effect first emerged (7-year-olds) for standard recognition in the semantic condition. A similar effect for recall was evident for 9-year olds, but not for younger children. Internal stimulus generation became a strong memory facilitator for phonetically encoded items at age 11 for standard recognition, but not until age 13 for recall. The results of the rhyme recognition test indicated that internal generation facilitated “transfer-appropriate processing” (C. D. Morris, J. D. Bransford, & J. J. Franks, Journal of Verbal Learning and Verbal Behavior, 1977, 16, 519–533) only for seventh graders (age 13). The processes underlying this developmental pattern were discussed.     

The self in transformation: the passage from a two- to a three-dimensional internal world

This paper seeks to describe some of the steps in the process of transformation from a two-dimensional to a three-dimensional inner world as experienced by a patient who had essentially used up her remaining vital resources. An important hurdle had first to be crossed when the analyst was required to demonstrate her capacity to survive with her in a two-dimensional claustrum, in a solitary confinement. Here, an oppositional defensive system had been created in which positive and negative personifications of vital but withdrawn energies ensured that she was locked within an interior world that sought to bar entry to anyone else, and where the possibility of the transformation of her self was disallowed. The patient had to accept the risk of breaching the system of self-defence before the analyst was allowed a mutual position within her interior world. A series of dreams tracks this transformation internally and in relation to the analyst.     

Defining motivation and cognition in animals

Motivation in an automaton, whether it be artificial or animate, is simply that aspect of the total state that determines the behaviour. In an autonomous agent, which has a degree of self‐control, the motivational state includes a cognitive evaluation of the likely consequences of possible future behaviour. Such evaluation implies optimization with respect to some motivational criterion.     

An administrative model for close monitoring and managing high risk individuals.

The public expects central government to have immediate knowledge of the condition and circumstances of certain vulnerable or dangerous individuals such as insanity acquittees, and to take action in individual cases to protect the individual and the public. Therefore, such persons conditionally released to community settings require an unusual degree of close monitoring and management. Being immediately aware of the condition and circumstances of its assignees, together with other duties of a board or commission responsible for that monitoring and management, is largely an information management function. The Psychiatric Security Review Board in Oregon is used to illustrate this unique mission, operations, and information management. In this paper, the Psychiatric Security Review Board is described in terms of its core and secondary businesses, together with a model information system that is based on information and information management processes actually employed by the Board.
