De Joux, Neil; Russell, Paul N.; Helton, William S. – Brain and Cognition, 2013
Despite a long history of vigilance research, the role of global and local feature discrimination in vigilance tasks has been relatively neglected. In this experiment participants performed a sustained attention task requiring either global or local shape stimuli discrimination. Reaction time to local feature discriminations was characterized by a…

Jeste, Shafali S.; Kirkham, Natasha; Senturk, Damla; Hasenstab, Kyle; Sugar, Catherine; Kupelian, Chloe; Baker, Elizabeth; Sanders, Andrew J.; Shimizu, Christina; Norona, Amanda; Paparella, Tanya; Freeman, Stephanny F. N.; Johnson, Scott P. – Developmental Science, 2015
Statistical learning is characterized by detection of regularities in one's environment without an awareness or intention to learn, and it may play a critical role in language and social behavior. Accordingly, in this study we investigated the electrophysiological correlates of visual statistical learning in young children with autism…

Sibuma, Bernadette – Journal of Interactive Learning Research, 2012
This study integrates agent research with a neurocognitive technique to study how character faces affect cognitive processing. The N170 event-related potential (ERP) was used to study face processing during simple decision-making tasks. Twenty-five adults responded to facial expressions (fear/neutral) presented in three designs…

Aman, Michael G.; Hollway, Jill A.; Leone, Sarah; Masty, Jessica; Lindsay, Ronald; Nash, Patricia; Arnold, L. Eugene – Research in Developmental Disabilities: A Multidisciplinary Journal, 2009
This study was designed to explore the placebo-controlled effects of risperidone on cognitive-motor processes, dyskinetic movements, and behavior in children receiving maintenance risperidone therapy. Sixteen children aged 4-14 years with disruptive behavior were randomly assigned to drug order in a crossover study of risperidone and placebo for 2…

Conner, J. D.; MacLeod, Donald I. A. – Science, 1977
Rod-isolation techniques show that light-adapted human rods detect flicker frequencies as high as 28 hertz, and that the function relating rod critical flicker frequency to stimulus intensity contains two distinct branches. (MLH)

Geisler, Wilson S. – Psychological Review, 1989
A new analysis, based on the concept of the ideal observer in signal detection theory, is described. It allows: tracing of the flow of discrimination information through the initial physiological stages of visual processing for arbitrary spatio-chromatic stimuli, and measurement of the information content of said visual stimuli.

Masland, Richard H. – Scientific American, 1986
Examines research related to the retina's coding of visual input with emphasis on the organization of two kinds of ganglion cell receptive fields. Reviews current techniques for examining the shapes and arrangement in the retina of entire populations of nerve cells. (ML)

Wolff, Peter – 1972
Several studies have indicated that children have difficulty differentiating mirror-image stimuli. In the present study adults were required to classify pairs of horseshoe stimuli as same or different. Response times were compared for stimulus pairs that varied in orientation (left-right vs up-down) and spatial plane of the pair (horizontal vs.…

Breitmeyer, Bruno G.; Ganz, Leo – Psychological Review, 1976
This paper reviewed briefly the major types of masking effects obtained with various methods and the major theories or models that have been proposed to account for these effects, and outlined a three-mechanism model of visual pattern masking based on psychophysical and neurophysiological properties of the visual system.

Ward, Ryan D.; Odum, Amy L. – Journal of the Experimental Analysis of Behavior, 2005
Discrepant effects of drugs on behavior maintained by temporal-discrimination procedures make conclusive statements about the neuropharmacological bases of timing difficult. The current experiment examined the possible contribution of a general, drug-induced disruption of stimulus control. Four pigeons responded on a three-component multiple…

Wisconsin Univ., Madison. ERIC Clearinghouse on Educational Facilities. – 1970
Many of the references in this bibliography are followed by a listing of ERIC descriptors to indicate the contents. The literature is pertinent to educational facilities design in providing for visual orientation, comprehension, and response to the physical environment. Listed items are presented in two sections: (1) human physiological,…

Haag, Brenda Bannan; Grabowski, Barbara L. – 1994
The purpose of this exploratory study was to examine the effectiveness of learner manipulation of visuals with and without organizing cues in computer-based instruction on adults' factual, conceptual, and problem-solving learning. An instructional unit involving the physiology and the anatomy of the heart was used. A post-test only control group…

Koester, Lynne S.; Farley, Frank H. – Education, 1980
A comparison of observed classroom behavior, tonic and phasic physiological arousal level, and task performance of 98 male and female first-grade children revealed sex differences in only 3 of 18 variables. Many assumed sex differences may be negligible and teachers' expectations may influence their perceptions. (SB)
