The Modulating Role Of Motor Action Anticipation In Relation To Visual Attention To A Scene, Rebecca Faith Wiener May 2016

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 …


Revisiting The Causal Link Between Finite Cognitive Capacity And Perseveration: A Dynamic Systems Account, Benjamin Craddock May 2011

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 …
