The purpose of this study was to extend understanding of the effects of aging on the female voice by obtaining measures of both acoustic and respiratory-based performance in groups of 18-30, 40-49, 50-59, 60-69, and 70-79-year-old subjects. Acoustic measures of speaking fundamental frequency (SFF), pitch sigma, jitter, shimmer, and signal-to-noise…

Objective: To determine whether there is an age-specific incidence of hospitalized cases of Shaken Baby Syndrome (SBS) that has similar properties to the previously reported ''normal crying curve,'' as a form of indirect evidence that crying is an important stimulus for SBS. Design and setting: The study analyzed cases of Shaken Baby Syndrome by…

The aim of the present study is to examine the reciprocal relationship between parental attachment and adolescent internalizing and externalizing problem behaviour. In this longitudinal study, 288 adolescents (mean age 13.5 years) reported on their attachment relationships with their parents and on problem behaviour three times, with…

Using the 1995 new cohort of the National Survey of Adolescent Males, this paper examines the association between perceptions of child support and adolescent males' sexual activity. The results indicate that adolescent males who expect the chance of being required to pay child support is high if one becomes a non-resident father or who has a…

This study found significant relationships between first- and second-order cultivation measures and TV viewing, but found a relationship with video game play for only two variables in a sample of 322 Flemish 3rd and 6th year secondary school children. This suggests that the absence of a relationship with video game play is not the result of the…

The present meta-analysis of the predictive validity of visual habituation and visual dishabituation shows that the weighted and normalized average correlation between infant habituation/dishabituation and childhood cognitive performance is 0.37. In contrast to the findings of earlier reviews, for risk samples, dishabituation is apparently…

The aim of this study was to investigate the relationship of fluid intelligence (gf) with trait Openness and Conscientiousness. A total of 2658 participants completed the NEO PI-R [Costa Jr., P. T. & MCrae, R. (1985). Revised NEO Personality Inventory and Five-Factor Inventory Professional Manual. Odessa, FL: Psychological Assessment…

Computing-related programmes and modules have many problems, especially related to large class sizes, large-scale plagiarism, module franchising, and an increased requirement from students for increased amounts of hands-on, practical work. This paper presents a practical computer networks module which uses a mixture of online examinations and a…

The peer relationships of young children with mild developmental (cognitive) delays recruited at 4--6 years of age were examined in a longitudinal study across a 2-year period. Results revealed only modest increases in children's peer interactions, a high degree of intraindividual stability, and the existence of a poorly organized and…

In this article, we discuss two characteristics of the majority of current behaviour- and molecular-genetic studies of reading ability and disability, specifically, the ascertainment strategies and the populations from which samples are selected. In the context of this discussion, we present data that we collected on a sample of Swahili-speaking…

A survey of the literature reveals that there is conceptual confusion and inconsistent and sometimes inappropriate usage of the terms racial identity, ethnic identity, and Afrocentric values. This study explored the extent to which Black racial(ized) identity attitudes were related to ethnic identity and Afrocentric cultural values. Two hundred…

Seven approaches to averaging reliability coefficients are presented. Each approach starts with a unique definition of the concept of "average," and no approach is more correct than the others. Six of the approaches are applicable to internal consistency coefficients. The seventh approach is specific to alternate-forms coefficients. Although the…

This study was designed to differentiate between structural description and bias accounts of performance in the possible/impossible object-decision test. Two event-related potential (ERP) studies examined how the visual system processes structurally possible and impossible objects. Specifically, the authors investigated the effects of object…

The purposes of this study were to determine the relationships between: (a) measures of body size/composition and heat production/storage, and (b) heat production/storage and heart rate (HR) drift during running at 95 % of the velocity that elicited lactate threshold, which was determined for 20 healthy recreational male runners. Subsequently,…

Individuals with posttraumatic stress disorder (PTSD) are often said to experience strong feelings of revenge. However, there is a need for confirmatory empirical studies. Therefore, in a study of 174 victims of violent crimes, the relation between feelings of revenge and posttraumatic stress reactions was investigated. Feelings of revenge were…
