Connectionist Models of Language Production: Lexical Access and Grammatical Encoding

Theories of language production have long been expressed as connectionist models. We outline the issues and challenges that must be addressed by connectionist models of lexical access and grammatical encoding, and review three recent models. The models illustrate the value of an interactive activation approach to lexical access in production, the need for sequential output in both phonological and grammatical encoding, and the potential for accounting for structural effects on errors and structural priming from learning.     

Social cognitive predictors of prosocial behavior toward same and alternate race children among white pre-schoolers

Social cognitive predictors of 36 White preschoolers' (18 boys, 18 girls) tendencies to say they would act prosocially toward White and African-American children were examined. White preschoolers completed measures of their tendency to engage in prosocial behaviors directed toward White and African-American children, positive racial beliefs about White and African-American persons, and race schematicity. Consistent with previous research examining prosocial behavior in preschoolers, girls were more likely than boys to say they would act prosocially. White preschoolers' age in months did not correlate significantly with their tendencies to engage in prosocial behaviors toward White children. However, age in months was negatively correlated with White preschoolers' inclinations to direct prosocial behaviors toward African-American children. Consistent with an emerging literature concerning the role of social cognitive factors in young children's race schema development, White preschoolers' race schematicity was significantly predictive of their tendencies to say they would engage in prosocial behaviors toward African-American children. Patterns of results partially replicate previous prosocial behavior research, and demonstrate the importance of social cognitive variables on young children's prosocial behaviors. This research was undertaken as part of a graduate program in psychology at the University of Wyoming by the first author under the direction of the second author. The authors express gratitude to Karen Bartsch, Ph.D., and Bernita Quoss, Ph.D., and Jesse Barber, Sylvia Jones, and Nicole Martin of the University of Wyoming and to Nancy Eisenberg, Ph.D., of Arizona State University.     

Ethnicity-Related Sources of Stress and Their Effects on Well-Being

Early research on ethnicity focused on the stereotyped thinking, prejudiced attitudes, and discriminatory actions of Euro-Americans. Minority-group members were viewed largely as passive targets of these negative reactions, with low self-esteem studied as the main psychological outcome. By contrast, recent research has increasingly made explicit use of stress theory in emphasizing the perspectives and experiences of minority-group members. Several ethnicity-related stressors have been identified, and it has been found that individuals cope with these threats in an active, purposeful manner. In this article, we focus on ethnicity-related stress stemming from discrimination, from stereotypes, and from conformity pressure arising from one's own ethnic group. We discuss theory and review research in which examination of ethnicity-related outcomes has extended beyond self-esteem to include psychological and physical well-being.     

Pabiku and Ga Ti Ga: Two Mechanisms Infants Use to Learn About the World

Some of the things that adults learn about language, and about the world, are very specific, whereas others are more abstract or rulelike. This article reviews evidence showing that infants, too, can very rapidly acquire both specific and abstract information, and considers the mechanisms that infants might use in doing so.     

Gender-Based Effects of Frames on Bullying Outcomes

The study extends research on the effect of frames. It is the first study to examine how framing affects the impact of being bullied. College students were randomly assigned to one of two groups: one framing bullying in terms of resilience and the other framing bullying with negative psychosocial consequences. Participants were asked to engage in a brief writing task aimed to actively create a frame and then completed both implicit and explicit measures. There was a significant main effect by gender and several significant interaction effects between frame and gender. These results suggest that framing impacts an individual’s conceptualization of emotionally salient personal memories and should be considered when developing bullying interventions. The impact of framing bullying may vary by gender.     

Improving visual spatial working memory in younger and older adults: effects of cross-modal cues

Spatially informative auditory and vibrotactile (cross-modal) cues can facilitate attention but little is known about how similar cues influence visual spatial working memory (WM) across the adult lifespan. We investigated the effects of cues (spatially informative or alerting pre-cues vs. no cues), cue modality (auditory vs. vibrotactile vs. visual), memory array size (four vs. six items), and maintenance delay (900 vs. 1800 ms) on visual spatial location WM recognition accuracy in younger adults (YA) and older adults (OA). We observed a significant interaction between spatially informative pre-cue type, array size, and delay. OA and YA benefitted equally from spatially informative pre-cues, suggesting that attentional orienting prior to WM encoding, regardless of cue modality, is preserved with age. Contrary to predictions, alerting pre-cues generally impaired performance in both age groups, suggesting that maintaining a vigilant state of arousal by facilitating the alerting attention system does not help visual spatial location WM.     

Reading Anxiety: An Early Affective Impediment to Children’s Success in Reading

Learning to read is a critical but often challenging academic task for young children. In the current study, we explore the relation between children’s reading affect-–particularly anxiety-–and reading achievement in the early years of reading acquisition. We hypothesized that reading anxiety would relate to reading achievement across the school year and that boys and girls might show differential patterns in the relation between reading anxiety and achievement due to the common stereotype that boys underperform in reading. A sample of first and second grade students completed measures of reading anxiety, positive reading affect, math achievement, and reading achievement in the fall and spring. Results show that reading anxiety and reading achievement share a bi-directional relation in which fall reading anxiety predicts spring reading achievement and vice versa. Furthermore, the pattern of relation between reading anxiety and achievement differs by gender: boys appear more susceptible to the reciprocal damaging effects of reading anxiety on reading achievement across the school year. Finally, reading achievement shares a stronger relation with reading anxiety than with positive reading affect, perhaps because of the phenomenon in which negative relative to positive experiences have a greater psychological impact.     

The paradox of the universal triangle: Concepts,language, and prototypes

For over 300 years, the humble triangle has served as the paradigmatic example of the problem of abstraction. How can we have the idea of a general triangle even though every experience with triangles is with specific ones? Classical cognitive science seemed to provide an answer in symbolic representation. With its easily enumerated necessary and sufficient conditions, the triangle would appear to be an ideal candidate for being represented in a symbolic form. I show that it is not. Across a variety of tasks—drawing, speeded recognition, unspeeded visual judgments, and inference—representations of triangles appear to be graded and context dependent. I show that using the category name “triangle” activates a more prototypical representation than using an arguably coextensive cue, “three-sided polygon”. For example, when asked to draw “triangles” people draw more typical triangles than when asked to draw “three-sided polygons”. Altogether, the results support the view that (even formal) concepts have a graded and flexible structure, which takes on a more prototypical and stable form when activated by category labels.
