Classical geometrical illusions strengthened or weakened under certain colour combinations.
Subjective curvature of visual space and some other geometrical characteristics depend not only
on visual form but also on colour. The hypothesis of colour generated visual geometry and its
measurable invariants will be discussed.
1063.63 Effect of distractors on the auditory attentional blink, Dawei Shen, Todd Mondor, the
Uiversity of Manitoba, Canada
Three experiments were conducted to determine whether the placement of distractors in a rapid
sequence of sounds has any influence on the auditory attentional blink. In these three experiments,
listeners were presented on each trial with a sequence of a variable number of tones that might
include a pre-defined target, a pre-defined probe, or both. Experiment 1 indicated that distractors
in the auditory stream were necessary to produce the auditory blink. Experiments 2 and 3 showed
that backward masking of the probe was the major factor in causing the auditory blink.

Gaps were introduced at some location during a target interval to be reproduced using a
peak-interval procedure. In this PI/GAP task, the interval, gap location and gap duration varied
from trial to trial (Experiments 1 and 2), and there were no gaps in 20% of trials in Experiment 2.
In both experiments, peak times were shorter when the gap occurred later during the target interval
presentation, and shortest peak times were obtained in trials with no gaps in Experiment 2. These
results demonstrate that the PI/GAP task may reveal effects attributable to expectation and
attentional time-sharing during timing.
1063.65 A test on cognitive fluctuation of timing estimation, Jinghong Le, Ningning Cao,
Minjing Jia, East China Normal University, China
32 subjects are required to estimate a duration in the form of same separations (estimate durations:
2500, 3000, 4000, 5000, 6000ms) continuously, the data are automatically recorded by the
computer. The test show there are some regular fluctuations in timing cognition. Under the
condition of non-reflex, the estimated error amplifies adhering to the trials increasing(duration
lasting); by one warning of correction, the estimation error reduces by the trials
increasing(duration lasting); in the level of 5s, the divergence seems to be significant,
demonstrating the fluctuation of the temporal estimation is roared by the increment of loading.
1063.66 The uses of music in everyday life, Adrian North, David Hargreaves, Lorraine
Sheridan, University of Leicester, UK
346 people were sent one text message per day over 14 days to their mobile phone, cueing them to
complete a questionnaire about any music they could hear. Most musical episodes occurred while
participants were alone; liking for the music depended on who the participant was with, where
they were, and whether they had chosen to hear music; music was usually experienced during the
course of some other main activity; exposure to music peaked at evening and the weekend; and the
functions of music varied according to temporal factors, location, and the presence of other
people.
