By synthesizing existing behavioural studies through a meta-analytic approach, the current study compared the performances of Autism spectrum disorder (ASD) and typically developing groups in audiovisual speech integration and investigated potential moderators that might contribute to the heterogeneity of the existing findings. In total, nine…

Purpose: Pitch plays an important role in auditory perception of music and language. This study provides a systematic review with meta-analysis to investigate whether individuals with autism spectrum disorder (ASD) have enhanced pitch processing ability and to identify the potential factors associated with processing differences between ASD and…

Purpose: Approximately 30% of adults over the age of 50 years present with altered vocal function. Our understanding of how these changes manifest acoustically and perceptually is derived from relatively modest-sized studies using a diversity of tools. Voice changes can arise from the onset of disease or disorder, but also age-related…

Purpose: The current meta-analysis provides a quantitative overview of published and unpublished studies on statistical learning in the auditory verbal domain in people with and without specific language impairment (SLI). The database used for the meta-analysis is accessible online and open to updates (Community-Augmented Meta-Analysis), which…

Prior studies have found that youth reporting a general sense that "I have a purpose" also describe having social supports that enhance thriving. This study links "specific" social supports to "specific" purposes described by youth. We examined whether developmental level, social-structural supports of gender and…

Although spoken language is communicated via a rapidly varying signal, human listeners recognize spoken words both quickly and accurately. Nonetheless, variability in speech does have implications for both the processes and representations involved in spoken language perception. Moreover, variability effects have been observed across the lifespan,…

Literature on children's drawing was reviewed for the purpose of illuminating issues of developmental stages, differences in development, perceptual problems, and instructional methods that influence learning in children's drawings. A glossary of terms used in the literature was compiled. Conclusions were drawn from the studies reviewed with a…

This paper reviews the research on speech perception and reassesses the contribution of innate capacities versus external stimulation in conjunction with age in first- and second-language acquisition. A developmental model of speech perception is then discussed in relation to neonatal auditory perception. (Contains 86 references.) (MDM)

In recent research, two qualitatively different classes of mental operations have been identified. The performance of one type of cognitive task requires attention, in the sense of mental effort, for its execution, while the second type can be performed automatically, independent of attentional control. Further research has shown that automatic…

Some recent research is examined on childrens' perception of pictures. Implications are drawn for those who create and use illustrated childrens' books. (SJL)

Recognizing that children today will spend almost half of their lives as grandparents, this paper examines grandparenthood and the grandparent-grandchild relationship. The paper focuses on the grandparent role, discussing styles and dimensions of grandparenting. A number of variables are discussed directly affecting grandparenting: (1) age of…

Business firms are an integral part of the age stratification structure of society. Although the age structures of people and roles within the organization are dynamic, these structures yield a fairly stable strata in which norms exist to suggest the various roles expected of certain persons. Those in roles with greater financial rewards, power,…
