Patterning, partial reinforcement, and N-length effects at spaced trials as a function of reinstatement of retrieval cues

摘要: Abstract Four experiments are reported which demonstrate the importance of reinstatement retrieval cues in partial-reinforcement using spaced trials. Reinstatement occurs when goalbox and startbox same brightness (gray). Nonreinstatement different brightnesses (black-and-white striped vs gray). Under conditions, both a effect (PRE) N-length effects were observed whether small reward or large was used. nonreinstatement PRE used but not used; either with reward. Finally, 24-hr intertrial interval, single alternation patterning found only group receiving reward, long nonreward confinement duration, reinstatement. These results consistent notion that massed trials governed by separate mechanisms, support an explanation based on E. J. Capaldi's sequential theory.
