Objective: to study the influence of factors of acute cerebrovascular accident or chronic cerebral ischemia on the processes of consolidation and reconsolidation of visual-image and auditory-speech memory. The project included was 108 people, the average age—65.6 ± 3.5 years; 3 samples were involved: with a diagnosis of I69.3—“Consequences of a brain infarction”—with left-sided and right-sided localization of the lesion and I67.8—“Other specified lesions of the cerebral vessels” (according to ICD-10).
The samples were gender-balanced. The reconstruction of F. Bartlett’s experiment was carried out.
In chronic cerebral ischemia, the instability of memory traces leads to a reduction and partial loss of visual-figurative and auditory-speech content. At the same time, in the process of reconsolidation of information, its concretization and simplification occurs. With left-sided localization of the focus of ischemic stroke, perception is characterized by a violation of the sequence of information processing. There is a holistic transfer with the loss of specific details. These features are caused by a hemispheric violation of successivity. Right-sided localization leads to the fact that while preserving information, its holistic perception is difficult—multiple details are transmitted, the general symbolism of the image and text is lost.
