visuospatial-domain working memory, Jiecai Lin, Zhicheng Jin, Weijun Fang, South China
Normal University, China
Most researchers have only explored the information of working memory in the verbal domain.
Oberauer established a concentric model distinguishing 3 states of information representations: the
activated part of long-term memory, the region of direct access, and the focus of attention. While
large numbers of behavioral and neurophysiological evidences prove the separability of the
verbal-domain working memory and the visuospatial-domain working memory. Based on the
concentric model, we explore the information representations in the visuospatial-domain working
memory by extending the memory-updating paradigm, then compare the information
representations in the visuospatial-domain working memory with those in the verbal-domain
working memory.
1063.138 Rehearsal of a spatial location, Bocheng Kuo, Yeiyu Yeh, National Taiwan University,
Taipei, China
The present study verified a hypothesis that selective attention is a rehearsal mechanism for spatial
working memory (Awh, Jonides & Reuter-Lorenz, 1998) or resource capacity may be the latent
factor that underlies the function of attentional-rehearsal. The results of Experiment 1 replicated
those of Awh et al. (1998) by showing that attentional shift influenced spatial working memory.
The results of Experiment 2 showed that spatial working memory was not impaired when
participants were asked to remember the temporal order of one or four colored circles during
retention interval. In Experiment 3, spatial judgment of orientation was performed during
retention.
1063.139 Activation and strategical coding in working memory scanning, Agata Blaut, Boryslaw
Paulewicz, Zbigniew Stettner, Jagiellonian University, Cracow, Poland
Two experiments were run in order to test the two-phase working memory scanning model. In the
first experiment classical Sternberg STM-search paradigm was modified to assess the amount of
resources taken up by the memory task. The second tracking task was added as a measure of
strategical coding of presented stimuli. The aim of the second experiment was to unconfound the
effect of mnemotechniques / strategical coding from stimulus driven activation. This was done by
controlling exposition time independently from ISI. The presently analysed results seem
promising.
1063.140Activation and inhibition in the preparation and execution processes in working memory,
Cuiju Bao, Zhicheng Jin, South China Normal University, China
The authors dissociated processes of preparation and execution in memory-updating task. In
experiment 1, increasing latencies with decreasing probabilities of stimuli showed that participants
can adjust their expectancies and activation on stimuli during the preparatory process. In
experiment 2, the author found that old men are slower in adjusting their expectancies than young
men. Experiment 3 showed the evidence that preparation involves activation of the expected
stimulus and inhibition of distracting stimuli, which supported interference theory. In experiment 4
the author found that there is backward inhibition in the processes of execution in
memory-updating task.
