2 studies are presented that document the spontaneous development by normal infants of nonverbal gestures to symbolically represent objects, needs, states, and qualities. These symbolic gestures are shown to be a typical rather than rare phenomenon of early development and to function in ways similar to early verbal symbols. Indeed, the case is made that(More)
Researchers have hypothesized in the past that children learning sign languages develop signs at an earlier age than is typically expected for vocal words. This assumption, however, has recently been questioned on the grounds that researchers have not always guaranteed that words and gestures are being used in a comparable fashion. The present study was(More)
Impact of Symbolic Gesturing on Early Language Development Susan W. Goodwyn, Linda P. Acredolo and Catherine A. Brown California State University, Stanislaus University of California, Davis San Diego State University (2000) Journal of Nonverbal Behavior, 24, 81-103. The purpose of the present study was to evaluate the effect on verbal language development(More)
In two longitudinal studies, infants were trained at 12 and 18 months to find an object hidden in one of two identical wells in a Plexiglas box. On the test trial, normal access was blocked and infants were either guided by their mother or allowed to move on their own to another opening on the opposite side. In Experiment 1 significantly more correct(More)
BLUESTEIN, NEIL, and ACREDOLO, LINDA. Developmental Changes in Map-reading Skills. CHILD DEVELOPMENT, 1979, 50, 691-697. The ability of 3-, 4-, and 5-year-old children to infer the position of an object in a room from information contained on a map was assessed under 5 conditions: (a) map aligned inside the room (the pretest); (b) map aligned outside the(More)
The effect of active exploration upon memory for spatial location of an event was assessed for children at 2 age levels. Each child took a walk through the same unfamiliar hallway in search of a hidden object which he was later asked to relocate. Half the children were accompanied by an adult holding their hand (passive condition), while the other half(More)
The impact of the hierarchical organization of a space on judgments of direction and distance was assessed in two studies using two-dimensional models analogous to those used by A. Stevens and P. Coupe (1978, Cognitive Psychology, 10, 422-437). In each study the models contained two stars and were divided into two parts by a curved boundary line. In the(More)
