Trajectories and predictors of indirect aggression: results from a nationally representative longitudinal study of Canadian children aged 2-10

The purposes of this study were to model the development of indirect aggression among a nationally representative sample of 1,401 Canadian children aged 4 at T2, 6 at T3, 8 at T4 and 10 at T5, and to examine predictors of trajectory group membership from T1 (age 2) child, familial, and parenting variables. Using a semi-parametric group-based modeling approach, two distinct trajectories were identified: "increasing users" comprising of 35% of the sample and "stable low users" comprising of 65% of the sample. Using logistic regression analyses to distinguish these two groups, we found that for girls, more frequent, increasing use of indirect aggression was associated with prior prosocial and physically aggressive behavior, low SES and low parental social support at age 2. For boys, increasing use of indirect aggression was associated with prior parenting issues at age 2-inconsistency and less positive parent-child interactions. Although this study provides unique information regarding the early development of indirect aggression and its predictors, more longitudinal research is needed to fully understand its development.     

Spatial navigation: Cognitive variables involved in route retracing among an elderly population

The cognitive processes involved in route retracing are not well known. This study aims to highlight them in an elderly population in which contradictory results have been obtained, certain studies showing specific difficulties for route retracing, others not. Thirty-nine elderly subjects performed a route-learning task (forward-backward) in a garden, then completed spatial knowledge tasks and standardised cognitive tests. Results show four factors that were predictive of route retracing performance: route repetition, the pointing task, and two standardised cognitive tests, one assessing spatial working memory, and another global cognitive efficiency. According to these results, route retracing involves route and survey knowledge (i.e., egocentric and allocentric strategy), and the integration of forward-backward perspectives is underpinned by the spatial working memory. Moreover, the subjects did not make more errors in route retracing than in the route repetition task, suggesting that a real environment could compensate for a failing allocentric strategy.     

What some effects might not be: The time to verify membership in 'well-defined' categories

Armstrong, Gleitman, and Gleitman (1983) reported shorter categorization times for members of well-defined categories judged more typical. They concluded that these effects could not originate in a graded, similarity-based category representation and consequently that the typicality effects obtained with natural categories might not be indicative of such a structure either. In this article, we re-examine this conclusion, focusing first on the performance obtained with well-defined categories of different sizes. Only the larger categories used showed variations in typicality ratings and produced typicality effects on categorization times. However,multiple regression analyses showed the effects on categorization times to be better explained by a measure of associative strength, called category dominance. The range of various predictor variables was equated in a follow-up experiment involving large, natural, and well-defined categories. Results obtained with well-defined categories showed pronounced dominance effects when typicality was controlled, but no reliable typicality effect when category dominance and instance familiarity were controlled. Results were opposite for natural categories. By showing that well-defined categories fail to produce unbiased typicality effects, our results bring added support to the hypothesis that the effects obtained with natural categories originate in a graded, similarity-based category structure.     

Situational consistency in behavioral patterns of aggressive boys: Methodological considerations on observational measures

The issue of situational consistency is of great interest for early intervention with aggressive boys, but efforts to show behavior stability across settings have been unsuccessful to date, due principally to methodological problems. It is argued here that a more appropriate matching of response form, interaction partner, and situations should increase the situation consistency of observed behavior. The results support this proposition in that, more crosssetting behavior consistency was found in the pairing of situations where aggressive boys (age 6–7 years) were interacting with an adult female (mother/child versus baby-sitter/child) than in the pairing of situations where the boys were interacting with an adult male (mother/child versus father/child) or with the teacher in a nondyadic situation (classroom). The implications of using an extreme group are also discussed.This research program was funded by Le Conseil Québécois de la Recherche Sociale, the Quebec Government's FCAR research program, the Social Sciences and Humanities Research Council of Canada, the Canadian Ministry of Employment and Immigration, and the University of Montreal FDR program.     

Gender-related effects in the perception of anger expression

The purpose of the study was to investigate the influence of sex of stimulus person, sex type of subject, and sex of subject on the social perception of anger expression. One hundred and sixty-six female and 100 male subjects completed a questionnaire that consisted of 10 vignettes depicting the expression of anger by either a female or a male stimulus person. For each vignette, subjects rated the psychological balance, expected frequency of behavior, perceived degree of anger, and appropriateness of behavior. Overall, female stimulus persons were rated higher on all dependent measures, but only male raters significantly differentiated between male and female stimulus persons. Generally, female subjects gave higher ratings, but viewed angry behavior as less appropriate than did male subjects. Ratings were also found to be related to subjects' scores on Extended Personal Attributes Questionnaire scales that involved socially undesirable traits. Post hoc analysis indicated that the type of anger response (“aggressive” or “nonaggressive”) was also an important variable, especially for the female subjects.     

Explicit syllable and phoneme segmentation in the young child

To write a language, one must first abstract the unit to be used from the acoustic stream of speech. Writing systems based on the meaningless units, syllables and phonemes, were late developments in the history of written language. The alphabetic system, which requires abstraction of the phonemic unit of speech, was the last to appear, evolved from a syllabary and, unlike the other systems, was apparently invented only once. It might therefore be supposed that phoneme segmentation is particularly difficult and more difficult, indeed, than syllable segmentation. Speech research suggests reasons why this may be so. The present study provides direct evidence of a similar developmental ordering of syllable and phoneme segmentation abilities in the young child. By means of a task which required preschool, kindergarten, and first-grade children to tap out the number of segments in spoken utterances, it was found that, though ability in both syllable and phoneme segmentation increased with grade level, analysis into phonemes was significantly harder and perfected later than analysis into syllables. The relative difficulties of the different units of segmentation are discussed in relation to reading acquisition.     

��Is Getting Well Ever An Art?��: Psychopharmacology and Madness in Robert Lowell��s Day by Day

On the publication of Robert Lowell's Life Studies in 1959, some critics were shocked by the poet's use of seemingly frank autobiographical material, in particular the portrayal of his hospitalizations for bipolar disorder. During the late fifties and throughout the sixties, a rich vein, influenced by Lowell, developed in American poetry. Also during this time, the nascent science of psychopharmacology competed with and complemented the more established somatic treatments, such as psychosurgery, shock treatments, and psychoanalytical therapies. The development of Thorazine was a remarkable breakthrough allowing patients previously thought incurable to leave hospital. In 1955, the release of Miltown, the first 'minor' tranquilizer, was heralded with a media fanfare promising a new dawn of psychological cure-all. These two events blurred the boundary between 'normality' and madness by making treatment in the community more widely possible and by medicalizing more commonplace distress. Lowell's early depictions of madness situate it as emblematic of the cultural malaise of 'the tranquilized fifties.' By his final collection, Day by Day (1977), mental illness had lost its symbolic power. These late poems explore the power of art as a way of representing and remedying suffering in a culture where psychopharmacology has normalized madness.     

Strategy selection and aging: impact of item concreteness in paired-associate task

The aim of this study was to examine the effect of aging on strategy selection in a paired-associate word task. Twenty-eight younger adults (mean age = 20.68 years) and 28 older adults (mean age = 68.46 years) studied 39 pairs of concrete, middle and abstract words. The concreteness level was manipulated in order to modify the benefit of imagery and sentence strategies in relation to task characteristics. The results showed an age difference in strategy selection in relation to concreteness level. Older adults showed less adaptive strategy selection for the imagery strategy but not for the sentence strategy. Change in strategy selection did not seem to be explained by better efficiency of sentence than imagery, so this study suggests a partial reduction of strategy adaptivity during aging.
