Abstract

Working memory, attention and executive control functions are central areas of neuropsychological research in schizophrenia. These concepts implicitly refer to the basic temporal structure of mental life as an integration of past, present and future. From a phenomenological point of view, they may be paralleled to the structure of internal time consciousness as analyzed by Husserl, consisting of a retentional, presentational and protentional function. These synthetic functions, operating at the most basic layer of consciousness, are capable of integrating the sequence of single moments into an ‘intentional arc’, enabling us to direct ourselves towards objects and goals in a meaningful way. On this background, basic symptoms of schizophrenia such as formal thought disorder, loss of automatic performances and disturbances of self-awareness may be conceived as caused by a weakening and dissolution of the intentional arc. A failure of the continuous intertwining of succeeding moments, and especially of the protentional function, leads to a loss of the tacit or operative intentionality that carries the acts of perceiving, thinking and acting. The loss of tacit, implicit functions undermines the common-sensical understanding of reality and has to be compensated by the deliberate, hyperreflexive reconstruction of everyday performances. Phenomenological analyses may thus establish a link between experimental research on single mental dysfunctions on the one hand and the higher level of the patient’s subjective experience on the other.
