72 college students learned 3 motor tasks under a blocked (low interference) or random (high interference) sequence of presentation. Retention was measured after a 10-min or 10-day delay under blocked and random sequences of presentation. Subsequent transfer to a task of either the same complexity or greater complexity than the originally learned tasks was also investigated. Results showed that retention was greater following random acquisition than under changed contextual interference conditions. Likewise, transfer was greater for random acquisition groups than for blocked acquisition groups. This effect was most notable when transfer was measured for the transfer task of greatest complexity. Results are considered as support for W. F. Battig's (1978) conceptualization of contextual interference effects on retention and transfer.
