The integration of semantic attribute and stimulus colour in a colour defined search space was
examined using the RSVP task. Participants were required to identify a target word defined by
colour from 9 distractor words one semantically associated with the target colour, the remaining
unassociated. Frequent errors were observed with the word immediately succeeding the target
misidentified as the target. However when the colour associated distractor appeared within two
words of the target it was misidentified as the target. The result suggests an influence of semantic
context on feature integration.
1063.20 Does empathy give insight in person perception? Billy Lee 1 , Tsuneo Kito 2 , 1 University
of Edinburgh, UK; 2 Kurume University, Japan
Is empathy blind or does it confer insight into another person? We assessed 138 observers using a
video test of veracity detection and felt empathy. There was no correlation between empathy level
and accuracy of detection. However, low empathic participants performed better than high
empathic on accuracy of veracity detection. Women received more empathy than men but men and
women empathised to the same degree. There was an interaction between observer and actor
gender. Number of siblings had no effect. The results suggest that in some cases self reported
empathy may hinder accurate person perception.

We investigated whether words embedded in longer words (e.g. car in careful) are activated when
processing the carrier word. Participants performed a Stroop task on primes and a lexical decision
task on targets. Primes were carrier words (e.g. redemption) with the letters comprising the color
word written in an incongruent color. Targets were (e.g. confession or were not (e.g. production
related to the meaning of the carrier word. Both a Stroop and a priming effect emerged. The results
show that focusing on task-relevant part of the stimuli allows semantic processing of both the
carrier and the embedded word.
1063.22 A study on the pattern of feature search under dual-task condition, Mowei Shen, Tao
Gao, Rende Shui, Haijie Ding, Zhejiang University, China
This research investigated the effects of set-size, top-down activation and first task on feature
search under dual-task condition. In Exp1 and Exp2, task one (T1) was to identify the unique letter
among Arabic numerals, task two (T2) was to detect a red dot. Distractors were grey dots in Exp1,
and dots with multiple colors in Exp2. In Exp3 and Exp4, T1 was to report the shape of a hexagon.
In Exp3, T2 was identical to that in Exp2; in Exp4, T2 was to detect “+” among “L”. The results
revealed the pattern of feature search was not changed by task switch.
1063.23 Effect of feature-changing on multiple-object-tracking, Rende Shui, Mowei Shen,
Zhejiang University, China
Many multiple-object-tracking (MOT) studies showed that people can track about four objects
simultaneously. Pylyshyn developed Visual Index hypothesis to explain it. Scholl and Pylyshyn’s
(1999) studies showed subjects could not detect the change of color or shape of the items in MOT
tasks; Dennis, John & Pylyshyn, Zenon's(2002) study showed that objects with different features
