Hierarchical Regulation of Involuntary Memory: Invo lvement into Activity, Lop Effects, and the Fate of Background Stimuli

Background. Activity psychology as a metatheory competes with cognitive in the explorative and predictive power. Phenotypical similarity of results obtained by these two approaches research on involuntary memory requires special analysis, which can be carried out testing applicability conceptual apparatus both theories (with highest relevance level processing framework) multifactorial studies. Objective. The study was aimed at direct experimental examination severity memorization an outcome performing tasks different requirements to processing: perceptual, semantic, self-referential. Sample. Eight hundred twenty-five volunteer students participated study, 598 females (72.5%) 227 males (27.5%). Methods. A set 15 visually overlapping dyads “picture-numeral” presented. Each participant randomly assigned perform one six either focusing pictures or numerals, requiring self-referential targets. At test, participants attempted recall all presented stimuli. Results. P.I. Zinchenko’s thesis that activity determines encoding way target stimuli are remembered much better than material perceived peripheral context empirically replicated. revealed inversion typical LOP effect for consisting decrease subsequent condition deeper processing. However, there standard background pictorial numeral-targeted tasks. To examine tendency conjunct numerals into entire objects during task performance, we inspected pairing recall. index predicted stimuli, increasing percentage explained dispersion from shadow deep In case control this index, sum remembering returned back LOP-effect. Conclusion. major contribution statistically confirmed. We observed LOP-effect targeted numerical terms A.N.
