Phonological memory and vocabulary learning in children with focal lesions

Eleven children with early focal lesions were compared with 70 age-matched controls to assess their performance in repeating non-words, in learning new words, and in immediate serial recall, a triad of abilities that are believed to share a dependence on serial ordering mechanisms (e.g.,; ). Results for the experimental group were also compared with other assessments previously reported for the same children by. The children with brain injury showed substantial impairment relative to controls in the experimental tasks, in contrast with relatively unimpaired performance on measures of vocabulary and non-verbal intelligence. The relationships between word learning, non-word repetition, and immediate serial recall were similar to those observed in several other populations. These results support previous reports that there are persistent processing impairments following early brain injury, despite developmental plasticity. They also suggest that word learning, non-word repetition, and immediate serial recall may be relatively demanding tasks, and that their relationship is a fundamental aspect of the cognitive system.     

Women's Reactions to Rape Victims: Motivational Processes Associated With Blame and Social Support1

A study was conducted with 128 female college students to test the hypothesis that when observers feel vulnerable to rape, they are more likely to blame a rape victim³ and are less willing to offer social support. Similarity and empathy were expected to moderate the effects of perceived vulnerability on blame and predict greater social support. Assumptions about the world were predicted to be associated with greater blame. A multivariate model was tested with structural equation modeling techniques. Perceived vulnerability did not directly or indirectly predict blame. However, similarity directly predicted less blame and indirectly predicted greater social support through associations with blame, perceived vulnerability, and empathy. World assumptions directly predicted greater blame and indirectly predicted less social support through blame. These findings suggest that blame and social support are interrelated processes which are associated with social observers' perceptions of the victim and their basic assumptions about the world.     

Age Expectations of Behavioural Autonomy in Hong Kong,Australian and American Youth: The Influence of Family Variables and Adolescents' Values

Tenth and 11th grade students from Hong Kong (N = 141), Australia (N = 155), and the United States (N = 155) completed questionnaires about the age at which they expected to achieve behavioural autonomy and about their family environments and values. In general, Hong Kong youth had later expectations for autonomy; described their families as less accepting-engaged and less structured; placed less value on individualism, outward success, and individual competence, and more value on tradition, prosocial, and well socialised outcomes. However, in all three cultures, age expectations for behavioural autonomy showed similar patterns of association with family environments and values as revealed by parallelism of regression planes. Expectations for later autonomy were associated with perceptions of parental monitoring, a demanding family environment, low levels of autocratic parenting, and with youths' de-emphasis of individualism, individual competence and outward success. In regression analyses the family environment and values scores reduced by 62% the influence attributed to culture.     

Traditionality of children's interests as related to their parents' gender stereotypes and traditionality of occupations

This study tested the common hypothesis that parents' gender stereotypes, maternal employment status, and the traditionality of parents' occupations, are associated with the traditionality of children's vocational interests. The traditionality of preschool children's (n=113) interests was examined by an instrument developed for the current study. Parents were administered the Attitudes toward Women Scale, and traditionality of their occupations was assessed. Only the traditionality of the mothers' occupations significantly correlated with the traditionality of the interests of both boys and girls. Other variables tested, as well as their interactions, were not found to show such relationships. The results were discussed in terms of the function of the role model in gender identity development and vocational schema modification.We thank Rachel Karniol for her helpful comments on an earlier draft of this article.     

Determination of visual figure and ground in dynamically deforming shapes

Figure/ground assignment - determining which part of the visual image is foreground and which background - is a critical step in early visual analysis, upon which much later processing depends. Previous research on the assignment of figure and ground to opposing sides of a contour has almost exclusively involved static geometric factors - such as convexity, symmetry, and size - in non-moving images. Here, we introduce a new class of cue to figural assignment based on the motion of dynamically deforming contours. Subjects viewing an animated, deforming shape tended to assign figure and ground so that articulating curvature extrema - i.e., "hinging" vertices - had negative (concave) contour curvature. This articulating-concavity bias is present when all known static cues to figure/ground are absent or neutral in each of the individual frames of the animation, and even seems to override a number of well-known static cues when they are in opposition to the motion cue. We propose that the phenomenon reflects the visual system's inbuilt expectations about the way shapes will deform - specifically, that deformations tend to involve rigid parts articulating at concavities.     

Does prime modality influence morphological processing?

Facilitation among morphologically related words generally is impervious to the prefixed or suffixed structure of primes and targets. A notable exception arises, however, when both primes and targets are suffixed. More specifically, when primes are auditory and targets are visual, facilitation for a suffixed target (e.g., payment) is absent when it follows a prime (e.g., payable) that is morphologically related and suffixed (Marslen-Wilson, Tyler, Waksler, & Older, 1994). To account for null facilitation (viz., the "suffix-suffix" effect), Marslen-Wilson and his colleagues posit inhibitory links between suffixes of morphological relatives. The present study assesses the generality of the "suffix-suffix" effect. When morphological facilitation is assessed relative to an orthographically related baseline, suffixed primes facilitate derivationally as well as inflectionally related morphological targets when primes are visual as well as auditory in both the lexical decision and naming tasks. The present findings call into question lexical models that posit inhibitory links between suffixes of morphological relatives.     

The processing and representation of Dutch and English compounds: peripheral morphological and central orthographic effects

In this study, we use the association between various measures of the morphological family and decision latencies to reveal the way in which the components of Dutch and English compounds are processed. The results show that for constituents of concatenated compounds in both languages, a position-related token count of the morphological family plays a role, whereas English open compounds show an effect of a type count, similar to the effect of family size for simplex words. When Dutch compounds are written with an artificial space, they reveal no effect of type count, which shows that the differential effect for the English open compounds is not superficial. The final experiment provides converging evidence for the lexical consequences of the space in English compounds. Decision latencies for English simplex words are better predicted from counts of the morphological family that include concatenated and hyphenated but not open family members.
