Light deprivation related changes of strategy selection in the radial maze
During the early postnatal age environmental signals underlie development of sensory systems. The visual system is considered as an appropriate system for evaluation of the role of sensory experience in postnatal development of sensory systems. In this study we evaluated the effect of visual deprivation on the usage of visuospatial cues in navigation of radial arm maze. Light (LR) and dark rear...

متن کاملEvidence for a link between changes to gaze behaviour and risk of falling in older adults during adaptive locomotion.
There is increasing evidence that gaze stabilization with respect to footfall targets plays a crucial role in the control of visually guided stepping and that there are significant changes to gaze behaviour as we age. However, past research has not measured if age-related changes in gaze behaviour are associated with changes to stepping performance. This paper aims to identify differences in ga...
متن کاملInfluences of state anxiety on gaze behavior and stepping accuracy in older adults during adaptive locomotion.
OBJECTIVES Older adults deemed to be at a high risk of falling transfer their gaze from a stepping target earlier than their low-risk counterparts. The extent of premature gaze transfer increases with task complexity and is associated with a decline in stepping accuracy. This study tests the hypothesis that increased anxiety about upcoming obstacles is associated with (a) premature transfers of...
متن کاملGazing into Thin Air: The Dual-Task Costs of Movement Planning and Execution during Adaptive Gait
We examined the effect of increased cognitive load on visual search behavior and measures of gait performance during locomotion. Also, we investigated how personality traits, specifically the propensity to consciously control or monitor movements (trait movement 'reinvestment'), impacted the ability to maintain effective gaze under conditions of cognitive load. Healthy young adults traversed a ...
