Reading :: Human Brain and Psychological Processes

Human Brain and Psychological Processes
By A.R. Luria


I just reviewed Luria's Higher Cortical Functions in Man, and if you read that review, this book will sound familiar. Luria published this present book in Russian in 1963, the year after Higher Cortical Functions; both books were published in English in 1966. We see many of the same themes, and Luria notes that the present book was also based on his work from 1938-1963.

In the introduction, Luria notes that interrupted higher mental functions such as writing, reading, and speech can be reconstructed along different paths (p.16). Drawing on Anoshkin, he uses the word "function" to "denote a complex adaptive activity of a whole system, and sometimes of a whole organism" (p.17). Again, he credits Vygotsky and Leontiev for their insights into the social-historical origin of human mental activity (p.21). He argues that an animal's behavior is a result of (a) inborn tendencies and (b) direct, individual experience; but humans can also tap into (c) the experience of mankind in general (p.21). This general experience is incorporated into activity, language, work products, and forms of social life. In fact, mediation—and Luria once again uses the example of the knot in the handkerchief—involves changing one's environment to control one's behavior from the outside, deliberately and socially. "All complex forms of voluntary attention and logical memory, conceptual perception and abstract intellectual activity are the result of the assimilation of socially-formulated activity and have a similar, complex structure. ... all these processes must be interpreted as products of social life, passing through a complex period of historical evolution, organized at different levels and carried out by means of highly involved forms of reflex activity, and all established through the conditions of existence of human society" (p.22).

Indeed, he quotes Vygotsky's Development of the Higher Mental Functions to argue that a function, initially social and shared by two people, gradually crystallizes to become a way to organize the individual's mental life (p.23). "The social-historical conditions of life do not abrogate the laws of reflex processes" developed during biological evolution, "but enrich and reorganize these processes, converting them into more complex functional systems, formed under the influence of objective activity, and with the close participation of language" (p.24).

A bit later in the book, Luria discusses functional location, drawing on Vygotsky, Leontiev, and Zaporozhets to argue "that individual behavioral processes are consistently interconnected during development and that in the process of ontogenesis, not only the structure of individual mental processes, but also their relationship to each other may change" (p.56). Interestingly, here he evokes the idea of "the concrete reflection of the outside world," arguing that this "reflection" "serves as the basis for the construction of new and more complex behavioral processes" (p.56). This interests me in that Soviet psychologists incorporated Lenin's theory of reflection, but understood it differently; Luria is using the term "reflection" here to denote senses, but keeping it separate from the construction of higher mental functions. See also p.3, in which Luria seems to say that direct senses are not psychological processes.

In discussing voluntary memory, Luria cites Vygotsky and Leontiev, noting that memory is compensated by the organizational role of the intellect (p.58).

And that's it for this review. The book becomes more complex here and delves into specific disturbances in thinking, which are fascinating but a bit far afield for my purposes. Like Higher Cortical Functions of Man, this book provides us with a good sense of how Luria applied Vygotsky's insights in his development of a new field, and for that reason, I recommend it.
