Research on joint attention and language learning has focused primarily on cues requiring visual access. However, this narrow focus cannot account for the emergence of language among some congenitally blind children who develop language on the same developmental timescale as their sighted peers. Findings from this longitudinal, retrospective study…

This article describes the physiological mechanisms involved in three-dimensional depth perception and presents a variety of distance and depth cues and strategies for detecting and estimating curbs and steps for individuals with impaired vision. (Author/DB)

Sighted (n=37), partially sighted (n=20), and blind (n=17) participants answered questions about their expression and interpretation of verbal and nonverbal cues during telephone conversations, face-to-face encounters, and dating. The groups used an equal number of cues. Results have implications for developing specific communication skills of…
