FISH: a commons dilemma simulation

A local-area-network-based commons dilemma (CD) simulation is described. The program usesfishing as its CD metaphor; research participants experience the metaphor through both graphics (fish may be seen in an ocean) and text (CD terms such as “resource regeneration” are translated to fishing terms such as “spawning”). Common CD parameters, such as the availability of the resource, payoff values, the number of harvesters, the rate of regeneration, knowledge about the state of the resource, and awareness of other harvesters’ actions may be varied Other CD parameters that are not yet widely studied may also be varied, such as variability in regeneration rate, uncertainty in the amount of the resource, operating costs necessary to harvest the resource, length of time for the resource to regenerate (spawn), and whether the resource is visible to harvesters. The program worked well in pilot testing and in a study in progress.     

Transformations from adjectives to Scales for the Adjective Check List (ACL): ACLTRANS FORTRAN IV program

The ACLTRANS ANSI FORTRAN IV program transforms the 300 adjectives on the Adjective Check List (Gough, 1950. 1960) into 37 raw and T-standard psychological scales. This program has three advantages over scoring based ob theAdjective Check List Manual (Gough & Heilbrun, 1965, 1980, 1983): ease and speed of computing the raw scale scores; exact partialing of number of adjectives checked from standardized scale scores; and choice of parameter norms for standardization. By using the ACLTRANS program, the researcher can be confident of quick and accurate scoring, as well as appropriate standardization.     

Case-like categories in children: The actor and some related categories

Case categories were investigated using a method in which pictures are presented accompanied by a sentence describing the scene: Preschool children learn to put tokens on the objects in the pictures according to the role each object plays in the scene as described. Generalization trials explore what the children include within the various roles. Children rapidly learn to associate tokens with case-like categories during the training phase, and readily transfer to new stimuli in generalization trials. The experiments demonstrate that children have a broad Actor category. The Actor “does” the action, and Actors are not necessarily animate. However, animacy is a class property of stimuli to which the children were very sensitive. There was evidence that User and Instrument are subcategories of Actor that are differentiated only when a sentence contains both. The data also suggest a Locative category, and Patient as a category of the grammatical object. Finally, the children appeared to treat subjects of predicate adjectives as a separate category, here called the Subject of Attribution, distinct from Actor, and functionally independent of objects of transitive verbs.     

Parent behavioral training: An analysis of the relationship among multiple outcome measures

The purpose of the present study was to examine the relationship among three types of outcome measures that have been employed to evaluate parent behavioral training: observational data collected by independent observers, parent-collected data, and parent-completed questionnaires. Previous research suggests that all three measures yield positive outcome data; however, a correlational analysis has not been performed to determine if the subjects who demonstrate the largest (smallest) change on one measure demonstrate the largest (smallest) change on the other measures. The present study undertook such a correlational analysis. Subjects were 20 young clinic-referred children and their mothers. Treatment consisted of a standardized parent training program to modifly child noncompliance. All three outcome measures (observational data, parent-collected data, and questionnaire data) indicated that therapy was effective. A correlational analysis performed on the outcome measures indicated a number of significant relationships for dependent variables withinthe observational data and withinthe questionnaire data; however, there were no significant relationships acrossthe three outcome measures. Although different outcome measures may yield similar conclusions about the effectiveness of parent behavioral training, the results suggest that any one subject, relative to other subjects, does not demonstrate uniform degrees of change across the three outcome measures. Explanations for the findings, as well as their implications, are discussed.This research was supported by NIMH grant MH-28859-01.     

Narcissistic characters with obsessive features: Diagnostic and treatment considerations

Conclusion In sum, in this article a mixed personality disorder is described that combines narcissistic and obsessive-compulsive features. These features include extreme perfectionism, narcissistic cathexis of the intellect, and obsessive-compulsive defenses against underlying narcissistic issues. In therapy, narcissistic characters with obsessive features frequently struggle between a need for engagement with and fear of engulfment by the therapist. Thus, while they may appear extroverted, they often remain aloof, and while they have a strong need to be understood, they frequently reject the therapist’s empathic statements. Therapy of the narcissistic character with obsessive features consists of two stages. In the first phase of treatment, the therapist addresses the patient’s narcissistic issues and provides an appropriate selfobject relationship. In the second phase of treatment (after greater self-development is established), the therapist begins to address the obsessive-compulsive issues of affective expression and control by assuming a more engaged, initiating, and personal stance with the client.     

Programming stimuli in matching to sample

In these investigations, a “teaching machine” was used to train pre-school and first-grade children in a series of progressively difficult discrimination tasks, leading up to matching to sample. Such training was much more efficient than training in the final discrimination alone. The errors the subjects made were found to be a functon both of the differences between consecutive discriminations (the “size of the steps” in the program) and the length of training on each discrimination. Theoretical and practical implications of these findings are discussed.     

The Two Worlds of Aggression for Men and Women

The purpose of this research was to assess differences in the nature of physical aggression experienced by men and women. Random digit dialing with Computer Assisted Telephone Interviewing was used to obtain a sample of 1,753 Ontario adults aged 18–60 (response rate of 67%). This method of sampling obtains respondents who reflect the ethnic and social diversity of Ontario. Respondents were asked to describe the most recent incident of physical aggression in which they had been personally involved during the past year. Most incidents reported by females were with a male opponent, usually a spouse, partner, or friend, did not involve alcohol consumption, resulted in high negative emotional impact, and pertained to jealousy. Incidents reported by males tended to be with other males, friends or strangers, in bars or public places, and involved four or more participants who had been drinking. Incidents involving only men had lower emotional impact on respondents and included more punching, threatening, and insulting behavior compared to incidents involving other gender combinations. These results are discussed in terms of the implications for violence generally and the importance of addressing male-to-male aggression and factors that foster this form of aggression.     

Experience and sentence processing: statistical learning and relative clause comprehension

Many explanations of the difficulties associated with interpreting object relative clauses appeal to the demands that object relatives make on working memory. MacDonald and Christiansen [MacDonald, M. C., & Christiansen, M. H. (2002). Reassessing working memory: Comment on Just and Carpenter (1992) and Waters and Caplan (1996). Psychological Review, 109, 35-54] pointed to variations in reading experience as a source of differences, arguing that the unique word order of object relatives makes their processing more difficult and more sensitive to the effects of previous experience than the processing of subject relatives. This hypothesis was tested in a large-scale study manipulating reading experiences of adults over several weeks. The group receiving relative clause experience increased reading speeds for object relatives more than for subject relatives, whereas a control experience group did not. The reading time data were compared to performance of a computational model given different amounts of experience. The results support claims for experience-based individual differences and an important role for statistical learning in sentence comprehension processes.
