“…For example, some studies have found inappropriate and negative interpersonal styles to be characteristic of LD children (Bruininks, 1978;Bryan et al, 19761, whereas others have been unable to attribute disruptive classroom behavior to them (Bryan, 1974a;Bryan & Wheeler, 1972). It has been suggested by some that the social communication difficulties experienced by LDs are more related to nonassertive and passive behaviors rather than to provocative or negative interactions (Bryan, Bryan, & Sonnefeld, 1982;Bryan, Donahue, Pearl, & Strum, 1981). Considering the previous research that has consistently found inappropriate, negative, and aversive social behaviors to be characteristic of hyperactive children (e.g., Campbell, Endman, & Bernfeld, 1977;King & Young, 1981;Klein & Young, 1979;Pelham & Bender, 1982), the results of the present investigation stimulate concern that past LD research has been confounded by the unexplained contribution of hyperactivity.…”
