For any of us, problem solving is a daily event. For some, it is a major task. This historical book puts to use neuropsychological methods to analyze the process of problem solving. Experience shows that the process is psychologically so complicated that standard methods established in pedagogy and psychology are insufficient to precisely determine individual factors hindering effective problem solving. The authors present techniques for rehabilitation training which could compensate for the impairments observed in individual cases. Luria's work has transformed rehabilitation training, enabling the evaluation of rehabilitation principles and methods. Luria's thinking and conceptual style reflect his genius and rich understanding of brain-behavior relationships. As those who have read it agree, Luria demonstrates remarkable insight with his complex analysis and his qualitative analysis is "breathtaking."
