[Neurophysiology and neuropsychology of recognition confabulation in hospitalized schizophrenic patients]. / Neuropsicología y neurofisiología de la confabulación de reconocimiento en pacientes esquizofrénicos hospitalizados.

Recognition confabulation was studied in 16 schizoprhenic patients and 16 normal controls. Half of the schizophrenics presented recognition confabulation, while the remaining 8 and 16 controls did not. This type of confabulation was associated to attentional deficiency, difficulties in perceptual follow-up and perceptive changes. These test satisfactorily discriminated confabulating schizoprhenics and both ill and healthy non-confabulating subjects. The possible mechanisms underlying this type of confabulation are discussed, in relation to the deficiences observed.
