Summary: The Project involves research of cognitive mechanisms in: visual perception, two aspects of memory (metamemory and action memory), and reading. In the visual perception study, our research of effect of stimuli orientation showed identification superiority of vertical and horizontal compared with oblique stimuli. On the basis of our research results dealing with perception accuracy of curved stimuli, the hypothesis about two means of curvature perception was proposed. The hypothesis assumes two means of curvature perception, depending on stimuli curvature degree. A slight curvature could be based upon integration of information about tangents on the arch of the curve. A high curvature could be based on the direct curve grasping. The study of action memory after encoding on different levels, demonstrated the level of processing effect. However, this level of processing effect is lower compared to the control verbal condition. It is considered that the reduction of level of processing effect indicates that action encoding per se provokes deep semantic processing. The action memory peculiarity is also revealed in the absence of the feeling of knowing effect for performed action as to-be-remembered items. In a standard verbal condition, feeling of knowing for unrecalled items is predictive for recognition memory performance. In the action performed condition there is no predictive power of feeling of knowing for subsequent recognition performance. The study of reading skill includes cognitive and motivational factors. For poor readers, decoding is relevant for the reading comprehension. Decoding is affected by visual-motor maturity and short-term memory, but the most important factor is phonemic awareness. Among motivational factors, only test anxiety influences reading directly.

Keywords: visual form perception, action memory, feeling-of-knowing, reading skill

Research goals: The aim of the proposed research is to find the basic characteristics of: - the cognitive processes, which are essence of the specific stimulus situations perception; - two aspects of memory; - reading. The aim of research of perception is to investigate some basic visual perception principles taking into account existance of specific perceptive (feature) detectors. The aim of research of curvature perception is to find out whether curvature is perceived "directly" (meaning that there are specific curvature detectors) or based upon integration of information about tangents on the curve's arch. The main expected contribution of this research concerns the new knowledge of basic perception processes principles. In memory research the first aim is to find out the way of functioning of memory monitoring with specific to-be-remembered information (actions). The second aim is to discover in what respect action memory is a specific kind of memory. The main expected contribution of this memory research is to add information that can give more light to the questions about memory of action. The aim of reading skill research is to find out relative importance of cognitive and cognitive-motivational factors. Expected contribution is collecting basic information about reading skill and application of acquired knowledge for developing efficient reading training programs and for treatments of reading difficulties.
