When two targets (T1 and T2) are embedded in rapid serial visual presentation (RSVP), T2 is often missed (attentional blink, AB) if T2 follows T1 by less than 500 ms. Some have proposed that inhibition of a distractor following T1 contributes to the AB, but no direct evidence supports this proposal. This study examined distractor inhibition by assessing a(More)
The mere exposure effect refers to the phenomenon where previous exposures to stimuli increase participants' subsequent affective preference for those stimuli. This study explored the effect of selective attention on the mere exposure effect. The experiments manipulated the to-be-attended drawings in the exposure period (either red or green polygons in(More)
Scrolling text presentation refers to a medium where multiple sentences can be presented in a limited space by drifting text from either right to left or bottom to top. In this study we explored the properties of reading scrolling text. First, looking at the actual scrolling devices in daily life, we surveyed the relationship between the scrolling speed and(More)
People do not accurately recognize the relative order of a letter sequence displayed in a rapid serial visual presentation when the letter sequence is presented repeatedly and the exposure of the letters is very brief in the first half of the presentation. This phenomenon is known as midstream order deficit (MOD), and is considered to reflect the limitation(More)
A sense of direction is said to depend on at least two factors, awareness of orientation and memory for spatial behavior. This study investigated whether these two factors could predict navigational performance in the actual world. Takeuchi's Sense of Direction Questionnaire (SDQ) was administered to 233 students, and two factors were identified: awareness(More)
We examined the effect of surrounding information on reading text that was scrolling from right to left inside a fixed window. In Experiment 1, participants adjusted the scrolling rate so that they could comfortably read the text scrolling in the window. Above or below the window, a character was flashed with a random stimulus onset asynchrony (SOA). The(More)
Attentional-load theory (Lavie, 1995) states that task load determines whether task-irrelevant stimuli are processed semantically. In three experiments students were asked to perform a Stroop-like task. They named a centrally fixated target color, while ignoring the task-irrelevant stimulus, which was an incompatible, compatible or non-color word. When(More)
As an evaluation of treatment for anterior crossbite (Class I Malocclusion) in the mixed dentition, relationships were examined between the results of cluster analysis on the measured values before treatment and those on the changes caused by treatment. The following were the results of the present investigation. 1. The results of cluster analysis on the(More)
