Dichhaptic laterality and field dependence

Relationships among laterality, field dependence, and sex were investigated using right handed subjects. Dichhaptic measures of laterality showed a significant left-hand advantage for the discrimination of irregular shapes. No significant relationships were found between laterality and sex or sex role perceptions nor between laterality and field dependence. A modality of response effect on the laterality task was interpreted in terms of the functional cerebral space principle.     

Selective encoding in the interpretation of topographic maps

In two experiments, practised adult map users compared three-dimensional landsurface drawings against previously and separately studied contour maps. In the first experiment, adding extra contour levels, or marked drainage patterns, led to increased map study and decreased judgement times, whereas adding both led to no further increase or decrease respectively. In the second experiment, removing minor surface details from the drawings produced no overall variation in judgement times. These findings were taken as suggesting that map users selectively encode features from the map in task-determined fashion.
