1063.15 The interference effect of different scale on visual spatial attention, Weiqun Song,
Yuejia Luo, Institute of Psychology, Chinese Academy of Sciences, Beijing, China
The dynamic brain mechanisms on the visual spatial attention affected by different scale
interference were investigated by with “precue-target” visual search paradigm of event-related
potentials (ERPs) in normal youth subjects. The results showed that the posterior P1 amplitude
evoked by target stimuli was larger when distractors were inside the cue range. However, the
posterior N1 and anterior N1 were smaller than that the distractors out of the cue range. These
indicated that the distribution of visual spatial attention not only increased the capacity of attentive
range but also weakened the interference out of the attentive rang.
1063.16 Attentional characteristics for moving stimulus in an orderly manner, Tomoki Ohashi,
Miyagi Gakuin Women's University, Japan
For investigating the characteristics of the attentional spotlight moving, most of the studies
concerned to examine how the attentional spotlight moves between two locations. In this study, we
conducted three examinations for investigating how the attentional spotlight allocates for the
moving stimulus in an orderly manner. For this purpose, we developed a new experimental
procedure that a pre-cue was moved regularly on a virtual circle as apparent motion stimulus.
Simple-RT and discrimination-RT were measured for detecting/discriminating a target presented
after the movement of the pre-cue. Results indicated the saliency of the stimulus was calculated
based on the movement direction.
1063.17 The meanings of Chinese characters affect the illusory conjunction under different task
conditions, Juan Liang, Zhicheng Jin, Wencun Wu, South China Normal University
This article is to investigate the effect of different kinds of Chinese characters on the illusory
conjunction. There’re two types of task conditions: single-task, dual-task; and two kinds of
characters: color-word, location-word; and three sorts of probe words: identical, feature and
conjunction. The findings indicate illusory conjunctions can occur under both task conditions. The
ICs are less when the meanings of the characters are identical to the written forms than when they
are different. So ICs are also affected by advanced factors such as meanings and propositions
except perceptual factors.
1063.18 Can the blink be blanked: Attenuating AB with a blank Frame, Wah Pheow Tan, Fook
Kee Chua, National Univeristy of Singapore, Singapore
In a set of two-target RSVP experiments, ISI was systematically manipulated between T1 and the
trailing distractor (D1). In some trials, (a) a blank, or (b) a letter identical to T1, was inserted
following T1. The two-stage (Chun & Potter, 1995) and interference (Shapiro et al., 1994) models
predict comparable AB modulation by the identical letter and the blank condition. Results showed:
(a) the T1-D1 ISI modulated AB; (b) the blank modulated but failed to eliminate AB; (c)
difference in effect between identical distractor and blank. Results are explained in terms of both
low-level and high-level masking by trailing distractor.
