Abstract

IN ENGLISH: This study reports a replication and extension of Ulrich and Dietz (1985) on the possible role of the short-term storage (STS) as a buffer memory between long-term storage (LTS) and the motor system in free recall tasks. This STS buffer would allow for the parallel unfolding of the search of LTS and the motor output of responses by temporarily storing retrieved items until their final production. In the study, this view was examined against the alternative hypothesis whereby the fast initial production of items in free recall relies on a controlled or “strategic” search of LTS rather than on the accrual of retrieved items in STS. In two independent replications, 54 native German language speakers and 39 native Bosnian language speakers performed letter verbal fluency task under the manipulation of STS preload (no preload vs. preload) and delay interval (1 sec vs. 10 sec between the presentation of the target letter and the signal for the start of recall). Contrary to the assumption of STS as a buffer memory, the results revealed that STS preload did not cancel out the effect of the delay. Accordingly, the results were interpreted in the context of controlled LTS search models. --------------- IN CROATIAN: Istraživanje je replikacija i proširenje studije Ulricha i Dietza (1985) o mogućoj ulozi kratkoročnoga pamćenja (KP) kao međumemorije između dugoročnoga pamćenja (DP) i motoričkoga sustava u zadacima slobodnoga dosjećanja. Takva međumemorija omogućila bi paralelno odvijanje pretrage DP-a i motoričke produkcije odgovora privremenim pohranjivanjem pronađenih čestica do njihove verbalizacije. U studiji je to stajalište suprotstavljeno alternativnoj hipotezi prema kojoj se brza inicijalna produkcija odgovora u slobodnome dosjećanju temelji na kontroliranoj ili „strateškoj” pretrazi DP-a, a ne na akumulaciji odgovora u KP-u. U dvjema neovisnim replikacijama 54 izvorna govornika njemačkoga jezika i 39 izvornih govornika bosanskoga jezika izvršavali su zadatak fonemske verbalne fluentnosti u uvjetima manipulacije opterećenja KP-a (bez opterećenja naspram s opterećenjem) i intervala odgode (1 s naspram 10 s odgode između prezentacije ciljnoga slova i signala za početak produkcije odgovora). Suprotno pretpostavci o KP-u kao međumemoriji, rezultati nisu pokazali da je efekt odgode poništen opterećenjem KP-a. U skladu s time rezultati su interpretirani u kontekstu modela kontrolirane pretrage DP-a.
