“…The present study was designed to examine infants' memory for feature relations as a function of retention interval and the possibility of dissociations in memory between features and feature relations. Although a number of researchers have reported that infants can perceive relations among object features very early in life (Bumham, Vignes, & Ihsen, 1988;Bushnell & Roder, 1985;Dannemiller & Braun, 1988;Fagan, 1977;Johnson & Schroeder, 1991;Slater, Mattock, Brown, Bumham, & Young, 1991), the novelty-preference paradigms used in these studies cannot be used to investigate the long-term retention of feature relations because they typically yield no evidence of retention longer than a few minutes at most (e.g., Roberts, 1988;Sherman, 1985). However, the mobile conjugate reinforcement paradigm used in our original study of infants' perception of correlated attributes indicated that infants as young as 3 months can remember feature correlations for at least 24 hours (Bhatt & Rovee-Collier, 1994a).…”
