There are considered the results of empirical research of efficacy of dynamic object control using stereoscopic image of spatial relations formed by gaploscopic method. It was found that improvement in control quality (compared with flat image in display) was obtained in dynamic disparity of the forming image. Realization of potential advantages of stereoscopic representation of space is related to its characteristics that facilitate the correspondence of perception and visual images of the real space.

Key words: stereoscopic image, gaploscopic method, visual perception, object control.

ATTENTION AND SHORT-TERM MEMORY INTERACTION: THE MEMORY STROOP EFFECT (2nd article)

The mechanisms of the memory Stroop effect (MSE) and memory facilitation effect (MFE) described in previous article are discussed. Analysis of subjective reports and dynamics of short-term memory task performance on Stroop stimuli showed that cognitive strategies (strategies of memory and attention) are important factor underlying the mechanisms. Classification of revealed strategies is presented. The magnitude of the effects is determined by the strategy specificity: if besides usual memory strategies subjects use strategies of attentional ignoring then MSE is increasing, but MFE is decreasing. This dependence is discussed within the theory of attention as a limited resources and mental effort.

Key words: attention, memory, strategies, Stroop task.
