Palatability of food as a factor influencing obese and normal-weight children''s eating habits

The type and amount of food leftover from school lunches by normal-weight and obese elementary school children was examined for its similarity to the pattern reported by Krassner et al. (1979) in a study of normal-weight and obese college students. In this study 102 observations of children between the ages of 9–11, were taken over eight lunch periods in their school cafeteria. Overall, the normal-weight children left only slightly more food uneaten than did the obese children. However, when food palatability was examined, it was found that normal-weight children left over twice as much palatable food as did obese children. Children did not differ on the amount of unpalatable food left uneaten.

These results suggest that Krassner et al.'s observation that obese adults leave less food on their plates may be extended to children and, further, that like obese adults, obese children may be more influenced by the palatability of food than their normal-weight peers.     

Temperament, distraction, and learning in toddlerhood

The word- and nonword-learning abilities of toddlers were tested under various conditions of environmental distraction, and evaluated with respect to children's temperamental attentional focus. Thirty-nine children and their mothers visited the lab at child age 21-months, where children were exposed to fast-mapping word-learning trials and nonlinguistic sequential learning trials. It was found that both word- and nonword-learning were adversely affected by the presentation of environmental distractions. But it was also found that the effect of the distractions sometimes depended on children's level of attentional focus. Specifically, children high in attentional focus were less affected by environmental distractions than children low in attentional focus when attempting to learn from a model, whereas children low in attentional focus demonstrated little learning from the model. Translationally, these results may be of use to child health-care providers investigating possible sources of cognitive and language delay.     

Attitudes Toward Affirmative Action in the United States and Canada

Attitudes toward affirmative action programs were investigated using a U.S. sample, an English speaking Canadian sample, and a French speaking Canadian sample. Results indicate that cultural influences in the form of individualism-collectivism were small but that ethnic and linguistic memberships were major influences on attitudes toward those programs.     

How Antisocial and Prosocial Coping Influence the Support Process Among Men and Women in the U.S. Postal Service

The influence of antisocial and prosocial copingon the acquisition of social support and on subsequentpsychological distress among 67 male and 47 femalepostal employees was examined allowing genderdifferences in coping to be studied in a single worksetting. Seventy seven percent of the respondents wereEuropean American, 18% were African American, and theremaining 5% were of varying ethnicities including:Asian American and Latin American. Employingstructural equation modeling, women were found to useprosocial coping as a coping response significantly morethan men, and men were found to use antisocial coping as a coping response significantly more thanwomen. Prosocial strategies were related to increasedworkplace social support in both the short-term andlong-term. Antisocial coping strategies were related to less support from co-workers in theshort-term. Contrary to predictions, antisocial copingstrategies were not related to decreased support acrosstime. Finally, increased social support was related to less psychological distress within eachassessment period.     

The development of English speech patterns of a 7-year-old Polish-speaking child

The silent period hypothesis was investigated by examining the speech development of AO, a Polish-speaking child, who emigrated to the U.S. at age 7 years, 5 months, and placed in the second grade of a rural Missouri school district in which there was no instruction of English as a second-language. AO was observed for 6 years, 8 months, in order to study the development of his English speech patterns. During this interval, recordings were made of five sentences produced by AO at five different age points and with recordings from a control group of native and nonnative speakers were rated by native American speakers. AO's accent showed a gradual decline during the first year of residence, receiving a rating of near-native speech. By age 14 years, 6 months, he was rated as having native speech performance. Observations of his language, social, and school development indicated that AO remained essentially silent during the first 6 months, using two- and three-word sentences only when necessary, that his social development was normal, and that his school achievement was not impeded by his placement in the grade level appropriate for his age. The conclusion was reached that AO's silent period experience contributed significantly to his development of English speech patterns.     

The influence of gender role typing on the expression of depressive symptoms

This study investigated the influence of gender role typing on the expression of depressive symptoms. Previous research (Padesky & Hammen, 1981) has found that men and women differ in their expression of depressive symptoms and has proposed gender role expectations as a possible explanation. This study considered gender role typing as a possible moderating factor of depressive symptoms. Undergraduates (99 men, 360 women) were divided into masculine and feminine groups according to the Bem Sex Role Inventory. Depressive symptoms were measured by the Beck Depression Inventory (BDI). Gender role typing differences emerged on the BDI with feminine subjects reporting more emotional symptoms than masculine subjects (p<.05) and masculine subjects reporting more withdrawal and somatic symptoms than feminine subjects (p<.05). The results are consistent with the hypothesis that depressive symptoms are influenced by societal expectations. Future research should consider the influence of gender role typing on the expression of depressive symptoms.     

Predicting Participation in Cancer Screening: The Role of Perceived Behavioral Control1

We examined the role played by perceived behavioral control in predicting participation in colorectal cancer screening among individuals recently informed that they were at high risk for this type of cancer. A telephone interview based primarily on the theory of reasoned action was administered to 96 high-risk individuals and 144 average-risk individuals. All participants then were sent materials needed to complete the screening test. In both groups, perceived behavioral control enhanced prediction of intention to complete the test over and above the contributions of attitude and subjective norm. In addition, perceived behavioral control had a direct effect on behavior but only in the high-risk group. Further, for high-risk subjects, knowledge about test procedures moderated the relationship of perceived behavioral control and intention to behavior, but in ways only partially consistent with theory. Finally, the model was better at predicting behavior in the average than in the high-risk group. We conclude that perceived behavioral control plays an important role in the prediction of screening behavior. Perceived behavioral control's motivational role manifests itself unambiguously through its influence on intention. The role of perceived behavioral control above and beyond its influence on intention, however, needs further study and clarification.     

Testing the assumptions and interpreting the results of the Rasch model using log-linear procedures in SPSS

This paper shows how to use the log-linear subroutine of SPSS to fit the Rasch model. It also shows how to fit less restrictive models obtained by relaxing specific assumptions of the Rasch model. Conditional maximum likelihood estimation was achieved by including dummy variables for the total scores as covariates in the models. This approach greatly simplifies the specification of the Rasch models. We illustrate these procedures in an analysis of four items selected from the Reiss Premarital Sexual Permissiveness Scale. We found that a modified version of the Rasch model with item dependencies fits the data significantly better than the simple Rasch model. We also found that the item difficulties are the same for men and women, but that the item dependencies are significantly greater for men. Apart from any substantive issues these results raise, the value of this exercise lies in its demonstration of how researchers can use the procedures of popular, accessible software packages to study an increasingly important set of measurement models.
