Older adolescent females' knowledge of child development norms

This study, the first of three designed to investigate different age groups' knowledge of developmental norms of children, focused on older adolescent female university students. Data were collected from 280 midwestern university students through a questionnaire consisting of 16 items focusing on physical and social development of children from birth to three years of age. Results showed that knowledge of normal development was both over- and underestimated regardless of age of student or year in school. These findings are discussed within the context of the importance of knowledge of developmental norms for future parents.     

Some comments on Shettel-Neuber and O'Reilly's "handedness and career choice: another look at supposed left/right differences" (1983)

A property of attitudes, namely, the fact that attitudes select facts, is used to comment upon a paper on handedness and career choice.     

The role of phonemes and syllables in the perceived similarity of speech sounds for children

In two experiments, we investigated the factors that influence the perceived similarity of speech sounds at two developmental levels. Kindergartners and second graders were asked to classify nonsense words, which were related by syllable and phoneme correspondences. The results support the existence of a developmental trend toward increased attention to individual phonemic segments. Moreover, one significant factor in determining the perceived similarity of speech sounds appears to be the position of the component correspondences; attention to the beginning of utterances may have developmental priority. An unexpected finding was that the linguistic status of the unit involved in a correspondence (whether it was a syllable or a phoneme) did not seem particularly important. Apparently, the factors which contribute to the perceived similarity of speech sounds in the classification task are not identical to those which underlie performance in explicit segmentation and manipulation tasks, since in the latter sort of task, syllables are more accessible than phonemes for young children. The present task may tap a level of processing that is closer to the one entailed in word recognition and lexical access.     

Children and cigarettes: The effect of a model who quits

Twenty-six previous studies were reviewed which demonstrated a consistent link between children's smoking uptake and exposure at home to an actively smoking older family member. The present study included another variable: the family model of smoking cessation. The smoking practices, intentions, and attitudes of 344 children aged 10–14 in Western Australia were anonymously assessed. Those with ex-smokers but no active smokers at home resembled children who had never been exposed to a smoking family model in being less likely to smoke now or intend to in the future, having fewer smoking chums, and believing that cigarettes had more personal and social disadvantages than their peers who shared households with active smokers. This suggested that any pro-smoking modeling while the ex-smoker was active had been counteracted by modeling of quitting. Implications for intervention were discussed.     

Reinforcer pathology,probabilistic choice,and medication adherence in patients with multiple sclerosis

The reinforcer pathology model posits that core behavioral economic mechanisms, including delay discounting and behavioral economic demand, underlie adverse health decisions and related clinical disorders. Extensions beyond substance use disorder and obesity, however, are limited. Using a reinforcer pathology framework, this study evaluates medical adherence decisions in patients with multiple sclerosis. Participants completed behavioral economic measures, including delay discounting, probability discounting, and a medication purchase task. A medical decision-making task was also used to evaluate how sensitivity to mild side effect risk and efficacy contributed to the likelihood of taking a hypothetical disease-modifying therapy. Less steep delay discounting and more intense (greater) medication demand were independently associated with greater adherence to the medication decision-making procedure. More generally, the pattern of interrelations between the medication-specific and general behavioral economic metrics was consistent with and contributes to the reinforcer pathology model. Additional research is warranted to expand these models to different populations and health behaviors, including those of a positive health orientation (i.e., medication adherence).     

A review on equivalence-based procedures to teach food-portion estimation skills

This review involved a systematic analysis of equivalence-based instruction (EBI) that aimed to improve food-size interventions in diverse populations. Systematic searches identified seven studies published since 2010 that met inclusion criteria. These studies were analyzed according to their participants, design, setting, content taught, training structures, training protocol, testing format, treatment integrity, and outcomes. Results showed EBI procedures for teaching food estimation skills have been mostly implemented with adults. The type of content taught in the identified studies included carbohydrate ranges, portion size with food and non-food items, measuring cups and nutritional content of calories. Majority of included studies used one-to-many training structure and simultaneous protocols for teaching stimulus relations. Five studies completed a generalization probe and three studies reported treatment integrity data. Overall, all participants demonstrated skill acquisition of novel relations between food and portion measurement aides. Recommendations for future research and clinical applications of EBI in teaching food portion estimation are presented.
