Gusev A.N., Mikhaylova O.A., Kremlev À.E.(2015).Attention and memory as determinants of change blindness . Moscow University Psychology Bulletin. Series 14.Psychology,1,20-41

The article presents the results of experimental study that found the effects of attention and working memory on the change blindness phenomenon manifestation. In “flicker” paradigm 93 participants solved the task of change detection in two consistently presenting images. The participants was divided into several groups by the magnitudes of concentration and allocation of attention, estimated using Bourdon’s correction test, as well as on the accuracy and time of identification of the target stimulus in the DMS working memory test. Found a positive influence of the concentration and allocation of attention on the search changes duration. The effects of working memory indexes were different: improving the accuracy of identification of the target stimulus was associated with an increase in the search time but in contrast the speed of identification positive effects on the search changes duration. The results allow to suppose that the specific role of attention and memory resources in the change blindness.

Korneev A.A., Kurgansky A.V.(2014). Change in order of movements constituting in series set by visual template. The Moscow University Herald. Series 14. Psychology, 2, 61-74

Whenever the reverse order of delayed execution of sequence of movements set by a visual template is required, the question arises as to how the sequence representation is stored in working memory (WM). One option is to first reverse the order of movements and then retain the result in WM. The other option is to retain the original order of elements and change it immediately before or during the sequence execution. In order to verify which of the two options takes place we conducted an experiment in which 14 adult (20—30 years old) subjects were asked to memorize the route of visual cursor moving along the invisible polygonal chains and after a given delay to reproduce the motion with a graphical tablet in either direct or reverse order. The analyses of latency and timing for the sequences produced in either direct or reverse order showed that the order reversal does not affect the latency but results in some increase of the time spent (pause) in the vertices of piecewise trajectories. It also shown that the order reversal effect neither spatial characteristics of the reproduced sequences nor the frequency of the erroneous reproduction. The reported results suggest that the reversal of the order of elements in a sequence of movements occurs during the sequence execution

The contribution of gamma and beta-rhythms in working (WM), dynamics of retaining traces of memory on a delay interval and definition of brain structures involved in processes of (WM) was studied by the new method of the micro structural analysis for event=related oscillatory brain activity. Research is carried out on 8 subjects who has to retain four different double-digit in five seconds delay for the subsequent comparison with target and no=target stimuli and the performing of motor reaction. Retaining traces of memory has intermittent character and on a delay interval is presented by periodic flashes in activity of frequency=selective gamma and beta generators in prefrontal, associative, visual cortex and cerebellum with the leading role of prefrontal cortex. Joint activity of local brain structures is provided with the frequency-selective generators working both on different frequencies, and on the common frequency.
