In translesion synthesis (TLS), specialized DNA polymerases (pols) facilitate progression of replication forks stalled by DNA damage. Although multiple TLS pols have been identified in eukaryotes, little is known about endogenous TLS pols and their relative contributions to TLS in vivo because of their low cellular abundance. Taking advantage of Xenopus(More)
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)
REV3 is the catalytic subunit of DNA polymerase zeta (pol zeta), which is responsible for the damage-induced mutagenesis that arises during error-prone translesion synthesis in eukaryotes. The related REV3L genes in human and mouse encode proteins of approximately 350kDa, twice as large as yeast REV3, but full-length REV3L has not been identified in any(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)
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)
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)
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)
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)
