A systematic evaluation of food textures to decrease packing and increase oral intake in children with pediatric feeding disorders

This study examined packing (pocketing or holding accepted food in the mouth) in 3 children who were failing to thrive or had inadequate weight gain due to insufficient caloric intake. The results of an analysis of texture indicated that total grams consumed were higher when lower textured foods were presented than when higher textured foods were presented. The gram intake was related directly to levels of packing. That is, high levels of packing were associated with higher textured foods and low gram intake, and low levels of packing were associated with lower textured foods and high gram intake. All participants gained weight when texture of foods was decreased. Packing remained low during follow-up for 2 participants even when the texture of food was increased gradually over time. These data are discussed in relation to avoidance, response effort, and skill deficit.     

Beyond Cinderella: relevant reading for young adolescents about stepfamilies

With the number of stepchildren increasing, it is important that books about stepchildren and stepfamilies be available in schools and other settings. Juvenile fiction is a good medium for exposing children to the complexities of stepfamily living, for reducing stereotypes, and for providing role models. This article examines and reviews adolescent fiction with step themes. By providing titles of recommended stepfamily literature, the teacher or helping professional can facilitate an adolescent's adjustment to stepfamily life and not leave him feeling that being in a stepfamily means living like either Cinderella or the Brady Bunch. A list of recommended books is included.     

Talking to children, foreigners, and retarded adults

Speech addressed to different categories of listeners was examined in a study in which undergraduate women taught a block design task to either a 6-year-old child, a retarded adult, a peer who spoke English as a second language (foreigner), or a peer who was an unimpaired native speaker of English. The speech addressed to children differed from the speech addressed to native adults along every major dimension that emerged in this study: It was clearer, simpler, and more attention maintaining, and it included longer pauses. Speech addressed to retarded adults was similar in numerous ways to the speech addressed to 6-year-olds; in some ways (e.g., repetitiveness), it was even more babyish. However, speech to the retarded adults did differ in timing from the other styles of speaking in that it included fewer and somewhat shorter pauses. Speech addressed to foreigners was more repetitive than speech addressed to native speakers, but in all other ways it was very similar. There was some evidence that speakers fine-tuned their communications to the level of cognitive and linguistic sophistication of their particular listener; for example, speakers addressing the more sophisticated foreigners (relative to those addressing the less sophisticated foreigners) used speech that included fewer devices for clarifying, simplifying, and maintaining the listeners' attention. We discuss the hypothesis that baby talk (the speech addressed to children) is a prototypical special speech register from which other special registers are derived.     

Reactions to Interpersonal Evaluative Feedback1

Self-enhancement approaches to self-concept provide a perspective for identifying motivational factors likely to be affected by interpersonal evaluative feedback. The main hypothesies were that in contrast to positive feedback, negative feedback would lead to higher self-esteem, lower perceptions of task importance, and lower perceptions of control over an evaluator's reactions. Students received a lesson on solving analogies from a teacher (confederate), and then took a test on analogies. After reviewing the student's test, the teacher conveyed either positive feedback, negative feedback, or no feedback. Consistent with a self-enhancement perspective, recipients of negative feedback increased their global self-esteem, placed less importance on succeeding at the task, and felt less control over the teachers' reactions. Implications for understanding the role of interpersonal evaluative feedback in motivation and self-esteem, and self-enhancing responses to threats more generally are discussed.     

Family structure and dating behavior of adolescents

This study investigated the effect of family structure on previous dating behavior of older adolescents, and examined the relationship of family structure, family relationship variables, and personal attributes to previous dating behaviors. Data were obtained from 96 males and 81 females enrolled in human development courses at two midwestern universities; 122 were from intact, nuclear families and 55 were from nonintact families. The Dating and Courtship Behavior Questionnaire, adapted from questionnaires by Winch (1949a) and Landis (1963), was administered to subjects during regular class periods. Family structure did not have an effect on number of partners or steadies, but adolescents from nonintact households began dating at younger ages than those from intact households. Personal attributes were more often related to dating behaviors than family structure or family relationship variables. Little support was found for the proposition that dating behaviors were affected by family structure.     

Self and Identity in Advanced Old Age: Validation of Theory Through Longitudinal Case Analysis

Case studies drawn from a 20-year longitudinal study of aging were examined for the support they provide to two theoretical viewpoints on the self in later life: one focusing on management of self-esteem, the other on development of identity as story. The five cases selected for scrutiny represented diverse trajectories of self-esteem. They furnished ample illustrations of certain key aspects of both theories, including assimilative processes of coping, depression related to absence of accommodation, maintenance of life story themes, and life review processes. They did not, however, give strong support to the dichotomy, drawn within both theoretical models, between younger and older old age. Examples of accommodation, disengagement, and self-transcendence, hypothesized to typify advanced old age, were relatively few in number and emerged only toward the very end of life. It is argued that examination of prototypical cases provides a useful approach to validating and developing theory. A conclusion drawn from this study is that more analysis should be carried out on the lives of persons who exemplify the theoretically ideal characteristics of advanced old age.     

Characteristics of the System of Production of History-of-Psychology Literature, 1975–1986

We used Psychological Abstracts to identify a large international sample of history-of-psychology literature that was published from 1975 through 1986. Information was obtained on such producer characteristics as: The language in which each publication was written; the country (or American state) from which it originated; and authorship gender and number. Differences in productivity were examined as a function of these variables and their combinations; comparisons were made with a random sample of psychological literature and with previously published findings regarding publication in psychology. Conclusions were drawn regarding the history of psychology considered as a literature-producing enterprise.     

Effects of partial reinforcement on conditioning,conditional probabilities,asymptotic performance,and extinction of the rabbit’s nictitating membrane response

Classical conditioning and extinction of the rabbit nictitating membrane response was investigated under 100 per cent, and two 50 per cent reinforcement conditions (50% equated total trials, and 50% equated reinforced trials) at average intertriai intervals (ITIs) of 30 and 60 sec. It was found that: (1) partial reinforcement reduced the rate of conditioning, but all groups eventually attained asymptomatic performance levels near 100 per cent; (2) first-order and second-order conditional probabilities following reinforced and nonreinforced trials were virtually identical; and (3) no partial reinforcement extinction effect (PREE) was observed.
