Extended visual fixation and distractibility in children from six to twenty-four months of ageJ E Richards
Department of Psychology, University of South Carolina, Columbia 29208, USA
Child Dev 72:963-72. 2001..This pattern of distractibility suggests attention increases over the course of a look toward the television, and that heart rate changes reflect this increase in attention...
Effects of attention on infants' preference for briefly exposed visual stimuli in the paired-comparison recognition-memory paradigmJ E Richards
Department of Psychology, University of South Carolina, Columbia 29208, USA
Dev Psychol 33:22-31. 1997..Thus, processing of briefly presented visual stimuli differs depending on the type of attention in which the infant is currently engaged...
Recovering dipole sources from scalp-recorded event-related-potentials using component analysis: principal component analysis and independent component analysisJohn E Richards
Department of Psychology, University of South Carolina, Columbia, SC 29208, USA
Int J Psychophysiol 54:201-20. 2004....
Cortical sources of event-related potentials in the prosaccade and antisaccade taskJohn E Richards
Department of Psychology, University of South Carolina, Columbia, South Carolina 29208, USA
Psychophysiology 40:878-94. 2003..The temporal proximity of this cortical activity and its relation to movement cueing suggests it reflects eye movement planning processes...
Extended visual fixation in the early preschool years: look duration, heart rate changes, and attentional inertiaJ E Richards
Department of Psychology, University of South Carolina, Columbia 29208, USA
Child Dev 71:602-20. 2000..Fixation patterns of children in this age range suggest attention increases over the course of a look, and parameters consistent with attentional inertia theory differentially develop in this age range...
Development of multimodal attention in young infants: modification of the startle reflex by attentionJ E Richards
Department of Psychology, University of South Carolina, Columbia 29208, USA
Psychophysiology 37:65-75. 2000..In contrast to selective modality enhancement for single-modality foreground stimuli, these results show that these multimodal stimuli engage both visual and auditory attention systems in this age range...
Localizing the development of covert attention in infants with scalp event-related potentialsJ E Richards
Department of Psychology, University of South Carolina, Columbia 29208, USA
Dev Psychol 36:91-108. 2000..These results suggest that cortical development parallels the development of covert orienting of attention and saccade planning in infants in this age range...
Infant attention and the development of smooth pursuit trackingJ E Richards
Department of Psychology, University of South Carolina, 29208, USA
Dev Psychol 35:856-67. 1999..This study shows that the development of smooth pursuit and targeted saccadic eye movements is closely related to the development of sustained attention in this age range...
Peripheral stimulus localization by infants with eye and head movements during visual attentionJ E Richards
Department of Psychology, University of South Carolina, Columbia 29208, USA
Vision Res 37:3021-35. 1997..These data also support the hypothesis that eye and head movement systems are relatively independent in the infant, and that eye-head relations during infant attention may be different from during inattention...
Extended visual fixation in young infants: look distributions, heart rate changes, and attentionJ E Richards
Department of Psychology, University of South Carolina, Columbia 29208, USA
Child Dev 68:1041-56. 1997..Infant fixation has characteristics similar to fixation in children and adults, and attention appears to increase over the course of a look in young infants...
Peripheral stimulus localization by infants: attention, age, and individual differences in heart rate variabilityJ E Richards
Department of Psychology, University of South Carolina, Columbia 29208, USA
J Exp Psychol Hum Percept Perform 23:667-80. 1997..These data suggest that infant attention affects decision processes for continuing focal stimulus fixation rather than peripheral stimulus discriminability...
Localizing cortical sources of event-related potentials in infants' covert orientingJohn E Richards
Department of Psychology, University of South Carolina, Columbia, SC 29208, USA
Dev Sci 8:255-78. 2005..Increases from 14 to 20 weeks in amplitude of the P1 validity effect and the presaccadic ERP could be modeled by an increase in activation in the corresponding cortical areas...
Infant attention and visual preferences: converging evidence from behavior, event-related potentials, and cortical source localizationGreg D Reynolds
Department of Psychology, University of Tennessee, Knoxville, TN 37996, USA
Dev Psychol 46:886-904. 2010..Visual preference also interacted with attention and stimulus type. The cortical sources of infant visual preferences were localized to inferior and superior prefrontal cortex and to the anterior cingulate cortex...
Cortical source localization of infant cognitionGreg D Reynolds
Department of Psychology, University of Tennessee, Knoxville, Tennessee 37996, USA
Dev Neuropsychol 34:312-29. 2009..We also describe the application of "realistic head modeling" to address some of the current limitations of infant cortical source localization...
Video comprehensibility and attention in very young childrenTiffany A Pempek
Department of Psychology, University of Massachusetts, Amherst, MA, USA
Dev Psychol 46:1283-93. 2010..The results suggest that it may not be until the middle of the second year that children demonstrate the earliest beginnings of comprehension of video as it is currently produced...
Familiarization, attention, and recognition memory in infancy: an event-related potential and cortical source localization studyGreg D Reynolds
Department of Psychology, University of South Carolina, Columbia, SC 29208, USA
Dev Psychol 41:598-615. 2005..The cortical source of Nc was located in areas of prefrontal cortex and anterior cingulate cortex...
Attentional inertia in children's extended looking at televisionJohn E Richards
Department of Psychology, University of South Carolina, Columbia, SC 29208, USA
Adv Child Dev Behav 32:163-212. 2004
Testing neural models of the development of infant visual attentionJohn E Richards
Department of Psychology, University of South Carolina, Columbia, SC 29208, USA
Dev Psychobiol 40:226-36. 2002..We concentrate on the effect of attention on eye movement control and show how animal-based models, indirect measurement in human infants, and direct measurement of brain activity inform this model...
Infants' attention to patterned stimuli: developmental change from 3 to 12 months of ageMary L Courage
Department of Psychology, Memorial University, Canada
Child Dev 77:680-95. 2006..Measures of heart rate change during sustained attention and the proportion of time spent in each phase of attention confirmed infants' greater engagement with the more complex stimuli...
