Effectively communicating environmental issues to motivate visitors' behavior is critical for zoos to accomplish their missions. We examined the relationship between zoo visitors' environmental concern and agreement with messages framed by environmental concern. Findings from two zoos (N = 298; N = 400), using two message formats, provided nearly…

Learning a new language involves substantial vocabulary acquisition. Learners can accelerate this process by relying on words with native-language overlap, such as cognates. For bilingual third language learners, it is necessary to determine how their two existing languages interact during novel language learning. A scaffolding account predicts…

Generativist models of grammatical development assume that children have adult-like grammatical categories from the earliest observable stages, whereas constructivist models assume that children's early categories are more limited in scope. In the present paper, we test these assumptions with respect to one particular syntactic category, the…

Purpose: To describe the development and preliminary evaluation of the Multicontext Sitting Time Questionnaire (MSTQ). Method: During development of the MSTQ, contexts and domains of sitting behavior were utilized as recall cues to improve the accuracy of sitting assessment. The terms "workday" and "nonworkday" were used to…

This article describes psychometric testing of an Icelandic adaptation of the "Adult Reading History Questionnaire" (ARHQ), designed to detect a history of reading difficulties indicative of dyslexia. Tested in a large and diverse sample of 2,187 adults, the Icelandic adaptation demonstrated internal consistency reliability (Cronbach's…

To date a significant share of the European population can be considered at risk of social exclusion. It has been argued that adult education programmes are a powerful tool to support vulnerable adults increasing their social inclusion. This study aims to answer the question if and which subgroups of vulnerable adults experience an increase in…

Purpose: Dog owners represent 40% of the population, a promising audience to increase population levels of physical activity. The purpose of this study was to develop and test the psychometric properties of a new instrument to assess social-cognitive theory constructs related to dog walking. Method: Dog owners ("N" = 431) completed the…

Studied the sample coefficient alpha for each of the five subscales of the Hopkins Symptom Checklist (HSL; L. Derogaitis and others, 1974) in a sample of 419 adults. Findings show that the normal-theory-based distribution has a systematic bias in describing the behavior of the sample coefficient alpha. (SLD)

This study presents detailed distributional analyses of voice onset times (VOTs) from seven 5-year-old children and 14 adults. Distributional non-normality was common in both data sets with children showing greater skew. Results suggest that theories of VOT development should not be based solely on means and standard deviations but need to address…

This study investigated the validity of Hayes's formula for converting rank-ordered Rokeach Values data to a normal distribution theoretically achieved through the use of rated data. Findings support the validity of Hayes's formula and expand the analytic possibilities of data collected on the Rokeach instrument. (Author/PN)

Distributions of psychiatric classifications among 42,479 persons with mental retardation were reviewed to determine relative rates of disorders for persons with both mental retardation and mental disorder. Analyses indicated that rates of reported schizophrenic and psychotic disorders were generally higher than expected relative to rates of other…

Reports conversational topics among same-sex adult friends, co-workers, siblings, parents and children. Confirms findings of previous researchers but also reveals insights concerning same-sex conversational interactions, especially the sex differences in talk about sports. Includes the self-report questionnaire and tables of reported frequency of…

A large-scale analysis was conducted of problem behavior by observing 20 individuals living in residential facilities. Data were converted into scatter plot formats. When the data were transformed into aggregate "control charts," 12 of 15 sets of data revealed 30-minute intervals during which problem behavior was more likely to occur.…

Determines the frequency distribution of Brainstem Auditory Evoked Potential variables (BAEP) for premature babies at different stages of development--normal newborns, infants, young children, and adults. The author concludes that the assumption of normality underlying most "standard" statistical analyses can be met for many BAEP…

A study involving 261 composers, 108 inventors, 392 NFL wide receivers, and 112 eminent inventors found that eminent individuals exhibit a greater rate of creative outputs and that the production of outputs deviates from randomness no more than would be expected from chance fluctuation alone, except for some eminent individuals. (Contains…
