A developmental-genetic analysis of aggressive behavior in mice (Mus musculus): III. Behavioral mediation by heightened reactivity or immobility?

This research was designed to investigate development and behavioral mediation in lines of ICR mice that have been selectively bred for aggressive behavior. General behavioral reactivity and behavioral immobility have been implicated as potential mediators by prior analyses of preattack interactions. To evaluate the separate roles of these dispositions, the emergence of attacks in genetically selected lines was tracked for 11 years by three levels of analysis: over successive generations, over development, and over dyadic interactions. Convergent outcomes were observed in all three levels with respect to two findings: (a) Robust line differences were obtained in attack behaviors, and (b) strong associations were found between line differences in attacks and line differences in behavioral immobility. Conversely, all three levels of analysis indicated a weak and inconsistent association between line differences in attacks and measures of social and nonsocial reactivity.     

The Creative Identity: Creative Behavior From The Symbolic Interactionist Perspective

This paper outlines a framework for understanding the motivation of certain creative behaviors from the perspective of symbolic interactionism. The fundamental tenets of symbolic interactionism are described, followed by a discussion of the mechanics of symbolic interactionist-based role-identity theory, and how the theory can be applied to the motivation of creative behavior. The paper also addresses directions for practical application and future research in this area.     

Syntactic influences on stuttering in young child stutterers

This study examined the location and rate of stuttering in the spontaneous speech of nine young stutterers (4.0–6.6 yr) in relation to certain aspects of syntax. It was designed to answer the following questions: Is there more stuttering at clause onset (boundary) than at other points in the clause? Does the type of clause influence rate of stuttering? Is there more stuttering on complex than on simple sentences? The syntactic analysis defined 10 clause types (seven pertaining to complex sentences and three pertaining to simple sentences); clause boundaries (taking into account “filler” words occuring in such positions); and hierarchical constituent structure within sentences. Stuttering was found with significantly greater frequency at clause boundaries than at internal (nonboundary) positions of clauses. This was apparent for nine of the 10 clause types, the exception being complement clauses. The word “and” at the beginning of simple and complex sentences provoked a high rate of stuttering. The hierarchical structure within the clause did not influence the location of stuttering, and sentence complexity was not a factor in the rate of stuttering.     

Alternate forms of the matching familiar figures test: a critical note

Criticism is leveled at attempts to develop alternative forms of the Matching Familiar Figures test when the literature suggests that what is required is a more reliable test, not simply an alternate version.     

A developmental-genetic analysis of aggressive behavior in mice: I. Behavioral outcomes

In order to investigate the proposal that modifications in developmental rate may mediate differences in aggressive behavior, two series of selective breeding studies were completed. Stable lines of mice that differed in the frequency and latency of attacks were rapidly established in two series (by S1 in the first series and S3 or S4 in the second series). For evaluation of the developmental-genetic proposal, an analysis was made of the ontogeny of aggressive expression in male mice of the two series, with a detailed report provided of the S1 and S4 generations of the second breeding series. Comparisons between the results of a longitudinal design and the results of a new type of cross-sectional design (involving only siblings, or co-sibial) indicated (a) a reliable developmental course of attack expression, with a sharp rise in early maturity and a slow decline thereafter; (b) a convergence in later maturity of the behavior of lines selectively bred for high or low aggressive behavior, if the animals had been assigned to the longitudinal design; (c) a strong effect of repeated testing on attack latency and frequency, even though the dyadic tests were brief in duration and separated by long intervals. In addition, cross-generational comparisons suggested that the selective breeding differences came about primarily by changes in the behavior of the low aggressive lines, in that these animals failed to show in early maturity the sharp increases in attack occurrence that were observed in earlier generations. Certain implications of these findings for developmental and evolutionary concepts (e.g., neoteny, acceleration, heterochrony) are discussed.     

Concurrent validity of a children's version of the Stroop Color-Word Test: the Fruit Distraction Test

To assess the concurrent validity of the Fruit Distraction Test, the Stroop Color-Word Test and the Fruit Distraction Test were administered to two groups of boys aged 12 yr. (N = 63) and 8 yr. (N = 52). Partial correlations, with IQ controlled, based on time and error scores derived from both tests, provided no convincing evidence that the Fruit Distraction Test is a valid downward extension of the Stroop.     

In sickness and in health: An exploration of some of the unconscious processes involved in the decision by family caregivers to place a family member with dementia in residential care

This paper explores the feelings, conscious and unconscious, evoked by the difficult decision to place a family member with dementia into residential care. In an exploratory study I interviewed five people who had made this decision with a view to exploring some of the unconscious processes involved in their decision-making. The interviews were interpreted paying attention to my understanding of the transference and my countertransference feelings and as triangulated by a psychodynamic supervision group.

Intimate contact with ageing and death evokes fears about mortality and activates primitive anxieties. The progress of dementia may amplify primitive or psychotic states of functioning, particularly those involving evacuatory projection, and family carers may resort to splitting off unbearable feelings of anxiety which such projections can evoke and may contribute to their decision to look for residential care.

Once placed in residential care different dynamics evolve and further difficult questions arise: how often to visit; whether and when to dispose of the person's possessions and ultimately how to grieve. The focus of this paper is, as far as it is possible, on the partner without dementia as an individual and the impact of their relative's dementia on their lives.
