Psychiatric patients (n = 107) and normal subjects (n = 100) were exposed to seven newly composed pieces of music orchestrated for a small symphony orchestra. The patients were divided into seven subgroups: schizophrenic, depressive and manic psychosis; obsessive, depressive, anxiety and hysterical neurosis. All subjects rated the music on semantic differential scales describing three factors of emotional experience: tension-relaxation, gaiety-gloom and attraction-repulsion. The ratings by patients in the different groups were compared with those by the normal subjects. Expressiveness in music was found to be communicated to patients in the same relative way as to normals. However, in the various diagnostic groups, several marked differences in experience were demonstrated. The main findings were that schizophrenic psychotics experienced the music as more attractive, while depressive and anxiety neurotics experienced it as less attractive, than normals. Depressive and manic psychotics experienced the music as less gay. Obsessive neurotics seem to be more sensitive to tension than normals.

Amphetamine added to maintenance therapy with neuroleptic drugs was accompanied by relief of complaints in 32 of 48 chronic schizophrenic patients with a long-standing incapacity for work. In 22 cases this relief was followed by increased work efficiency. These gains were lost at experimental withdrawal of amphetamine. The response to amphetamine varied with type of schizophrenic symptomatology. All current regressive symptoms meant worsening in spite of concomitant neuroleptic treatment, in accordance with the dopamine hypothesis. Non-regressive subjects displaying florid symptoms, however, benefited. Worsening, in a few cases, occurred only in the absence of neuroleptics. A few subjects with negative symptoms only, seemed totally unresponsive. These findings point at variations in sensitivity to dopaminergic stimulation in schizophrenic subjects. Worsening and improvement with amphetamine were each clearly connected with type of symptomatology only when current psychotic or florid non-regressive symptoms were exhibited. In cases with negative symptoms only, the type of response could not be reliably based on clinical data. Studies of autonomic functioning and attention were therefore performed in a sub-sample. Skin conductance level, reactivity and habituation rate were found to be lower in positive responders before amphetamine. After amphetamine there were no such differences. Attention tests showed no initial differences between groups but the performance of positive responders improved with amphetamine.
