“…Of those sharing studies cited in the literature, most could be clas sified as dealing with the learning of sharing through models (Harris, 1970;Rosenhan & White, 1967), rehearsal (Rosenhan & White, 1967), and reinforcement (Doland & Adelberg, 1967;Fischer, 1963;Harris, 1970;Midlarsky & Bryan, 1967); sharing as reciprocity (Harris, 1970;Staub & Sherk, 1970); the effects of dependency relationships on sharing , 1964Berkowitz, Klanderman, & Harris, 1964;; and the relationship of sharing to need for approval (Staub & Sherk, 1970), socio-economic status (Ugurel-Semin, 1952;Wasik, Senn, & Epanchin, 1969), and age, sex, and family size (Handlon & Gross, 1959;Ugurel-Semin, 1952). Thus it appears that there is a need for more research on the topic of sharing.…”
