Perceptual learning is an improvement in one's sensory abilities after training and is thought to help us to better adapt to the sensory environment. Here, we show that perceptual learning also can lead to misperceptions, such that subjects actually perceive stimuli when none are physically presented. After learning, subjects not only showed enhanced(More)
Studies of psychopharmacology often use the test of the critical flicker fusion (CFF) threshold as a measure of total information processing. It is true that studies of practice effects have shown that CFF thresholds are remarkably stable within and across multiple days of testing. This study confirms that subjects who undergo CFF testing on sequential days(More)
The growing ethnic and racial diversity of the United States is evident at all spatial scales. One of the striking features of this new mixture of peoples, however, is that this new diversity often occurs in tandem with racial concentration. This article surveys these new geographies from four points of view: the nation as a whole, states, large(More)
This study explored the relation between visual processing and word-decoding ability in a normal reading population. Forty participants were recruited at Arizona State University. Flicker fusion thresholds were assessed with an optical chopper using the method of limits by a 1-deg diameter green (543 nm) test field. Word decoding was measured using(More)
Critical flicker fusion thresholds (CFFTs) describe when quick amplitude modulations of a light source become undetectable as the frequency of the modulation increases and are thought to underlie a number of visual processing skills, including reading. Here, we compare the impact of two vision-training approaches, one involving contrast sensitivity training(More)
This study examines foraging strategy in the ecologically-valid, real-world setting of a competitive Easter Egg Hunt. Foraging studies often test marginal value theorem (MVT), an optimality model that describes ideal foraging behavior in patchy environments with diminishing returns. A typical setting for studying MVT is picking in an apple orchard. Here, a(More)
Research suggests that the key to optimal student learning, regardless of class size, is engaging students in active learning. It is my contention that to truly understand neural processing, one must not only understand the activities of the neuron as a living cell, but also how that cell works within the context of a neural network. The demonstration(More)
