In 1974 and 1976, Luria presented successively his two-volume research study titled "The Neuropsychology of Memory". The first volume was titled "Memory Dysfunctions Caused by Local Brain Damage" and the second "Memory Dysfunctions Caused by Damage to Deep Cerebral Structures". Luria's book written in the 1960s titled "Basic Problems of Neurolinguistics" was finally published in 1975, and was matched by his last book, "Language and Cognition", published posthumously in 1980. Luria's last co-edited book, with Homskaya, was titled "Problems of Neuropsychology" and appeared in 1977. In it, Luria was critical of simplistic models of behaviorism and indicated his preference for the position of "Anokhin's concept of 'functional systems,' in which the reflex arc is substituted by the notion of a 'reflex ring' with a feedback loop." In this approach, the classical physiology of reflexes was to be downplayed while the "physiology of activity" as described by Bernshtein was to be emphasized concerning the active character of human active functioning.
