This narrative review analyzes the visual and auditory advantages that autistic people with speech divergence (A-SD) may have compared with autistic people without speech divergence (A-NoSD) or non-autistic people. Importantly, A-SDs' intelligence and communication skills are often underestimated in research and practice. Further, this paper…

Purpose: The contributions from the central auditory and cognitive systems play a major role in communication. Understanding the relationship between auditory and cognitive abilities has implications for auditory rehabilitation for clinical patients. The purpose of this systematic review is to address the question, "In adults, what is the…

The report is organized into two sections: the first summarizes and evaluates research that has tried to uncover basic information processing skills that account for individual differences in intelligence;…

Studies reporting predictions from assessments of infant recognition memory to later developmental performance and IQ are critiqued. Inelegancies in design, procedure, and analyses are noted.

This booklet addresses the following key findings in intelligence research: intelligence is not fixed or…
