The equivalence of two methods of parameter estimation for the rasch model

Two methods of estimating parameters in the Rasch model are compared. It is shown that estimates for a certain loglinear model for the score × item × response table are equivalent to the unconditional maximum likelihood estimates for the Rasch model.     

Perturbation and Lethality as Precursors of Suicide in a Gifted Group

ABSTRACT: Thirty cases, for whom longitudinal personality data were available from 1921 to 1960, were analyzed. All the cases were Caucasian males with high I.Q.'s. Five individuals had committed suicide (all by gunshot), 10 (matched) individuals had died natural deaths from cancer or heart disease, and 15 were still living. A blind clinical analysis was conducted primarily in terms of two guiding concepts, perturbation and lethality, by means of a Meyerian “life chart” and a “psychological autopsy,” respectively. The results indicated that four of the five cases deemed to be most suicidal had, in fact, committed suicide—a chance probability of 1 out of 1,131. The prodromal clues—instability, trauma, and personality controls—are discussed. The role of the “significant other” and the “burning-out” of affect seem to be paramount. Suicide is seen as a discernible part of a life style and as a predictable outcome, in a person of 50, by the time that individual is 30 years old.     

The cultural ecosystem of human cognition

Everybody knows that humans are cultural animals. Although this fact is universally acknowledged, many opportunities to exploit it are overlooked. In this article, I propose shifting our attention from local examples of extended mind to the cultural-cognitive ecosystems within which human cognition is embedded. I conclude by offering a set of conjectures about the features of cultural-cognitive ecosystems.     

‘Make sure you keep our house safe!’ Thematic analysis of a children's psychotherapy group

This paper describes a systematic thematic analysis of one particular latency-aged children's group and includes a discussion about potentially helpful outcomes measures. The impetus for our small, practice-based qualitative research project came from the two papers by Reid (1999) and Canham (2002) about children's psychotherapy groups, particularly Canham's (2002) paper, ‘Group and gang states of mind’. Canham and Reid used Bion's theories of group functioning as the basis of their technique with children's groups. We felt that it would be an interesting follow-on from Reid and Canham's findings to explore in some detail the specific therapeutic factors involved in a shift from paranoid–schizoid to depressive functioning in group therapy. We hoped that this might give us some helpful clinical indications as to the circumstances in which group rather than individual psychotherapy and parallel parent work should be considered as the treatment of choice. The paper concentrates exclusively on group work with latency-aged children, therefore referring mainly to the limited number of papers published about psychoanalytic group therapy with this age group.

Exhibitionistic Human Movement Responses of Strippers: An Attempt to Validate the Rorschach M

A group of women employed as strippers produced significantly more exhibitionistic M on the Rorschach than three other matched control groups. Results were interpreted as supporting the position that the human movement response is related to actual behavioral tendencies.     

A Comparison of Rorschach Records of Three Multiple Personalities

Inter- and intra-protocol comparisons among the Rorschachs of three authenticated cases of multiple personality were presented. The original or primary personalities seemed reasonably complex but, as successive personalities emerged, a definite tendency toward simplification was noted. A theoretical explanation for this phenomenon was advanced.
