Is the word-length Effect linked to subvocal rehearsal?
Cortex, 2011Co-Authors: Charlotte Jacquemot, Emmanuel Dupoux, Anne-catherine Bachoud-léviAbstract:Phonological short-term memory Subvocal rehearsal Word-length Effect Articulatory suppression Conduction aphasia a b s t r a c t Models of phonological short-term memory (pSTM) generally distinguish between two components: a phonological buffer and a subvocal rehearsal. Evidence for these two components comes, respectively, from the phonological Similarity Effect and the word-length Effect which disappears under articulatory suppression. But alternative theories posit that subvocal rehearsal is only an optional component of the pSTM. According to them, the depletion of the length Effect under articulatory suppression results from the interference of the self-produced speech rather than the disruption of subvocal rehearsal. In order to disentangle these two theories, we tested two patients with a short-term memory deficit. FA, who presents a pseudoword repetition deficit, and FL, who does not. FA's deficit allowed for the observance of an ecological case of subvocal rehearsal disruption without any articulatory suppression task. FA's performance in pSTM tasks reveals as controls a phonological Similarity Effect, and contrary to controls no word-length Effect. In contrast, the second patient, FL, exhibits the same Effects as control subjects. This result is in accordance with models of pSTM in which the word-length Effect emerges from subvocal rehearsal and disappears when this latter is disrupted.

The Effect of viewpoint on visual stimuli: a study of episodic memory in schizophrenia.
Psychiatry Research-neuroimaging, 2010Co-Authors: Mathieu B. Brodeur, Marc Pelletier, Michael Bodnar, Lisa Buchy, Martin LepageAbstract:article In everyday life, objects are rarely perceived in the exact same position as they were the first time. This change of position alters the perceptual viewpoint influencing the likelihood of recognizing the object — the Similarity Effect. Moreover, this Effect may be a contributing factor to the overall episodic memory deficits that are apparent in people with schizophrenia. The present study investigated the influence of viewpoint on memory recognition in 43 schizophrenia and 23 healthy comparison participants. Photos of target objects were presented during the encoding phase alone and then during the recognition phase (as an old object) along with never-before presented objects. The old objects, however, now appeared either from the same viewpoint (unaltered condition) or from a different viewpoint (altered condition). Participants performed an old/new discrimination task during the recognition phase. Results, for both groups, revealed better recognition performance when the viewpoint was unaltered; that is, memory recognition was sensitive to viewpoint manipulation. There was no significant interaction however, between this Similarity Effect and

There was no significant interaction however, between this Similarity Effect and group. Thus, visual functions solicited by changing the viewpoint, as well as the influence on the encoding and the subsequent memory retrieval, are likely intact in people with schizophrenia.

ICONIP (3) - Word frequency Effect and word Similarity Effect in korean lexical decision task and their computational model
Neural Information Processing, 2006Co-Authors: Youan Kwon, Kinam Park, Soon Young JungAbstract:In this paper, we investigate whether the word frequency Effect and the word Similarity Effect could be applied to Korean lexical decision task (henceforth, LDT). Also we propose a computational model of Korean LDT and present comparison results between human and computational model on Korean LDT. We found that the word frequency Effect and the Similarity Effect in Korean LDT were language general phenomena in both the behavioral experiment and the proposed computational simulation.
