USE OF TEXTURE FADING IN THE TREATMENT OF FOOD SELECTIVITY

Children with feeding disorders often display severe food selectivity. For many of these children, consuming highly textured foods may be aversive or potentially dangerous because of frequent gagging. The purpose of this study was to demonstrate the efficacy of texture fading in the treatment of food selectivity displayed by 4 children. Treatment involved the gradual addition of higher textures based on the results of periodic probes. In addition, food acceptance and swallowing were reinforced, while food refusal and food expulsion were placed on extinction. Results showed that all participants successfully advanced to consumption of age-appropriate texture and volume. The results suggest that texture fading with intermittent probes at higher textures may be an effective method for the treatment of food selectivity by texture.     

Postpartum Depression: An Overview

Occurring in about 12% of postpartum women, postpartum depression has been the focus of considerable research. Variables that have been correlated with postpartum depression range from biological causes, to lack of social support, to relationship with husband, to attributional styles, to psychodynamic explanations. There is a need for a more circumscribed operational definition of the syndrome and norming of depression measures. It is also important to assess each person individually and to design interventions that focus on particular contributive factors.     

Another Round for the Brewers: Television Ads and Children's Alcohol Expectancies1

In an experimental study of how beer commercials affect alcohol expectancies, 92 fifth graders watched 40 television ads that included either five beer commercials, five soft-drink commercials, or five beer commercials plus two antidrinking messages. Afterwards, as an unrelated task, they completed the Alcohol Expectancy Questionnaire-Adolescent Form (AEQ-A; Christiansen, Goldman, & Inn, 1982). Exposure to different commercials produced no differences in drinking expectancies. The experiment was repeated on 74 eighth graders with similar null results; however, eighth-grade girls more strongly believed (p <.02) that alcohol leads to deteriorated cognitive and behavioral function. In a comparison of fifth and eighth graders from the same school, eighth graders had significantly more positive scores on three AEQ-A scales that tapped social/emotional expectancies. The failure of beer commercials to create positive alcohol expectancies is consistent with limited and null findings of previous investigations. Research to date does not support a ban on alcohol advertising.     

Navigation,browsing, and understanding in an anatomical “hypermedia” environment

A variety of theories of how spatial information is represented in cognitive models have been proposed and numerous strategies (e.g., fish-eye views and nested boxes) have been devised to assist users in browsing and navigation within hypertext and “hypermedia” information systems. These methods of spatial information representation, as well as hypermedia browsing and navigation strategies, are discussed in relation to human anatomy, and a model graphics-based browsing tool, which makes use of the classical regional (spatial) and systematic (functional) arrangement of the human body, is illustrated. This browsing scheme is described in relation to human anatomy, but could be used with other complex spatially organized systems (e.g., in engineering). The integration of this graphics-based browsing tool with other established textually-based strategies is discussed.     

Lexical integration: Sequential effects of syntactic and semantic information

Both semantic and syntactic context constraints can influence word processing at the level of lexical integration. In event-related brain potentials (ERPs), semantic integration is reflected by a negativity around 400 msec (N400), whereas phrase structure assignment and syntactic integration are assumed to be reflected by an early left anterior negativity and a late positivity (P600), respectively. An ERP study is presented in which participants read different types of sentences whose terminal verb was either congruent with the preceding context or incongruent due to a phrase structure violation, a semantic violation, or both. The main finding was that only the pure semantic violation condition, but not the combined semantic and syntactic violation condition, elicited a large N400. The two conditions containing phrase structure violations were predominantly characterized by a P600. Both semantic violation conditions, moreover, displayed a late negativity around 700 msec that overlapped with the P600 in the double violation condition. The absence of an N400 effect for elements that are syntactically as well as semantically incongruent with prior context suggests an early influence of phrase structure information on processes of lexical-semantic integration. The present data are discussed in comparison to previous ERP findings, and a new view of lexical integration processes is proposed.     

Familiarity and recollection in item and associative recognition

Recognition memory for item information (single words) and associative information (word pairs) was tested immediately and after retention intervals of 30 min and 1 day (Experiment 1) and 2 days and 7 days (Experiment 2) using Tulving's (1985) remember/know response procedure. Associative recognition decisions were accompanied by more "remember" responses and less "know" responses than item recognition decisions. Overall recognition performance and the proportion of remember responses declined at similar rates for item and associative information. The pattern of results for item recognition was consistent with Donaldson's (1996) single-factor signal detection model of remember/know responses, as comparisons based on A' between overall item recognition and remember item recognition showed no significant differences. For associative recognition, however, A' for remember responses was reliably greater than for overall recognition. The results show that recollection plays a significant role in associative recognition.     

Applications of social cognitive theory to the career development of women of color

This article provides a review of the literature on the educational and career development of women of color within the context of social cognitive career theory (Lent, et al, 1994 and Lent, et al, 1996). Specifically, possible gender, ethnic, racial, and cultural influences on career self-efficacy and outcome expectations are explored to delinate the potential mechanisms whereby ethnicity, culture, and ethnic and racial identity development, in interaction with gender, affect career choice and adjustment. Suggestions for future research on social cognitive career theory and the career development of women of color are presented.     

Processing Grammatical Gender During Language Comprehension

The paper reviews empirical evidence on the processing of grammatical gender during language comprehension, mainly focusing on gender priming. Evidence comes from behavioral experiments investigating gender priming and from behavioral as well as neurophysiological experiments evaluating the interaction of gender priming with semantic information. While the behavioral data do not provide a completely unambiguous picture, the neurophysiological data and the most reliable behavioral effects are more in line with a modular than with an interactive view of lexical access.     

An Initial Look at Sibling Reports on Children's Behavior: Comparisons with Children's Self-Reports and Relations with Siblings' Self-Reports and Sibling Relationships

The authors examined siblings' reports of children's depression, anxiety, and aggression, and their reports of the sibling relationship, and compared them with children's self-reports. In two samples, including 169 sibling pairs (age M = 9.98 years, SD = 1.51), no significant differences emerged in the levels of depression and anxiety found in siblings' reports of children's behavior and children's self-reports, although siblings reported children to have significantly higher levels of aggression than the children self-reported. Age, the difference in ages between siblings, sex, and sibling sex were not related to siblings' reports of children's behavior. The relations between children's and siblings' reports of children's behavior were significant, yet moderate (average r = .22). Both siblings' self-reports of internalizing behavior and their perceptions of aspects of the sibling relationship (affection, rivalry, hostility, and satisfaction with the sibling relationship) explained significant, and unique, variance in siblings' reports of children's internalizing behavior. The findings for aggressive behavior were similar, although siblings' perceptions of affection in the sibling relationship were not significantly related to their reports of children's aggression. The potential uses and benefits of sibling reports of children's behavior, and sibling and family relationships, are discussed.
