Perceptual Load and Color Singletons 1 Running head: PERCEPTUAL LOAD AND COLOR SINGLETONS Does Low Perceptual Load Enable Capture by Color Singletons?
There is considerable debate as to whether color singletons can capture attention in a stimulus-driven manner. In this study, we explore one potential capture enabling condition – low perceptual load. To test this hypothesis, we manipulated perceptual load in a flanker task in which flanking letters sometimes were color singletons. If low load enhances capture by color singletons, then color si...

بررسی رابطه دانش همنشینی لغات و مهارت نوشتاری در زبان انگلیسی چکیده این پژوهش درصدد آن است تا سه مسئله زیر را مورد بررسی قرار دهد: الف) وجود یا عدم وجود رابطه بین دانش زبان آموزان در حوزه همنشینی لغات با یکدیگر و دانش آنها در مهارت نوشتاری زبان انگلیسی؛ ب) یافتن پاسخی به این سوال که آیا تمامی انواع همنشینی های لغوی زبان انگلیسی به یک میزان برای زبان آموزان دشوارند یا خیر؛ پ) مقایسه زبان آمو...
15 صفحه اولCortical Synchronization and Perceptual Salience
We present a striate-cortical model which proposes a direct relationship between cellular synchronization and perceptual salience. The model focuses on the role of the longrange horizontal connections between oriented simple cells in striate cortex and is able to account for current physiological and psychophysical results on contour salience. We demonstrate that horizontal connections between ...
متن کاملAnxiety overrides the blocking effects of high perceptual load on amygdala reactivity to threat-related distractors.
Amygdala reactivity to threat-related distractor stimuli can be abolished in perceptually demanding contexts. Premised on the biological imperative to respond swiftly to threat, we demonstrate, however, that when participants are threatened by shock, greater amygdala responses to fearful compared to neutral distractor faces is preserved under conditions of high attentional demand. Lateral prefr...
متن کاملThe Rapid Perceptual Impact of Emotional Distractors
The brief presentation of an emotional distractor can temporarily impair perception of a subsequent, rapidly presented target, an effect known as emotion-induced blindness (EIB). How rapidly does this impairment unfold? To probe this question, we examined EIB for targets that immediately succeeded ("lag-1") emotional distractors in a rapid stream of items relative to EIB for targets at later se...
