Infant Object Recognition: Two- And Three-Dimensional Visual Processing, Alexandra Chelsea Romano
Infant Object Recognition: Two- And Three-Dimensional Visual Processing, Alexandra Chelsea Romano
Masters Theses
Visual attention and recognition memory in infancy are highly dependent on the type of stimulus the infant is familiarized to and the conditions of familiarization. For example, in studies that initially exposed infants to test stimuli in laboratory settings (e.g., Courchesne, Ganz, & Norcia, 1981; Reynolds & Richards, 2005), the Negative Central (Nc) event-related potential (ERP) component associated with infant visual attention has shown greater amplitude for novel compared to familiar stimuli. Conversely, when initial stimulus exposure occured outside of the laboratory and the stimulus was highly familiar, studies have shown greater amplitude Nc to familiar compared to novel stimuli …
The Modulating Role Of Motor Action Anticipation In Relation To Visual Attention To A Scene, Rebecca Faith Wiener
The Modulating Role Of Motor Action Anticipation In Relation To Visual Attention To A Scene, Rebecca Faith Wiener
Masters Theses
This study investigates how visual attention to a scene is modified when the actor has a reaching goal or not. Thirty-six 7-month-olds were recruited, with 18 in a reaching group and 18 in a non-reaching group. Infants in both groups were presented with objects out of their reaching space until they accumulated approximately six seconds of active looking as measured by an eye-tracker. For the infants in the non-reaching group, the trial ended after the six seconds. For the reaching group, the object was then moved into the infants’ reaching space where they could reach for it. We were interested …
The Effect Of Local Element Density On Processing Of Visual Hierarchical Patterns: An Infant Erp Study, Sara M. Mosteller
The Effect Of Local Element Density On Processing Of Visual Hierarchical Patterns: An Infant Erp Study, Sara M. Mosteller
Masters Theses
Previous research with infants, children, and adults has shown that global, or configural, information is processed before local, or featural, information in high density visual hierarchical patterns (Freeseman, Colombo, & Coldren, 1993; Ghim & Eimas, 1988; Kimchi, 1988; Navon, 1981; Navon, 1977). The current study used event-related potential to determine if a well documented bias toward global processing in infancy can be disrupted when the number and density of local elements is reduced through increasing the distance between elements. Infant responses were compared between high and low density conditions to global and local novel patterns and to familiar patterns. A …
Revisiting The Causal Link Between Finite Cognitive Capacity And Perseveration: A Dynamic Systems Account, Benjamin Craddock
Revisiting The Causal Link Between Finite Cognitive Capacity And Perseveration: A Dynamic Systems Account, Benjamin Craddock
Masters Theses
The current study revisits the causal link between finite cognitive capacity and infant perseveration originally put forth by Berger (2004) wherein perseverative errors resulted from a limited amount of cognitive resources. A dynamic systems perspective was used to test the interaction of a limited cognitive capacity and task difficulty by manipulating the contextual layout of Berger’s stair A-not-B paradigm (i.e. from 90-degrees to 180-degrees). Two groups of infants, differing in walking experience but not in biological age, were presented the task of descending A-side 5 consecutive times and to B-side on the 6th trial. Perseveration was not seen in either …
