A failure to train the "same-different" differentiation of photic stimuli in dogs.

Dogs were unable to learn "same-different" differentiation of pairs of photic stimuli when continuous light (CL) and pulsing light (PL) were presented in four combinations: CL-PL and PL-CL served as S(D) (positive instrumental conditioned stimulus), whereas CL-CL PL-PL were S delta (inhibitory stimulus). Also the dogs which have learned this task with tones were unable to transfer to photic stimuli. Differentiation of the single stimuli (CL and PL) as S(D) and S(delta) was quite easy and showed that the stimuli were readily discriminable.

Transfer of the "same-different' differentiation task in dogs.

Four dogs, previously trained to perform on the "same-different" differentiation with tones transfered readily to the same task with new stimuli of the same (auditory) modality. The data are interpreted as an support for the "matching" hypothesis and a disproof of the notion of "conditioned switching".

[Follow-up studies of psychotic patients receiving inpatient treatment or alternative forms of psychiatric care].

An analysis of populations treated in the III Department of Psychiatry indicates that 12 years since the transformation of the organizational model of care for patients from sub-regionalized catchment area, inpatient treatment continues to be of major importance, as it was provided to over half of all referrals. Intermediate forms of care, replacing a half of the former number of psychiatric beds, were offered mainly to schizophrenic patients, with the exclusion of those with a marked agitation, psychomotor retardation, or aggressive, presenting imminent danger to self or others. At one-year follow-up J.E. Overall's scale was used to examine 39 schizophrenic patients treated at the inpatient ward, day hospital, or by a community treatment team. Patients treated at the day hospital providing an intense therapeutic program manifested a significantly more marked improvement in respect of 6 symptoms: autism, affective bluntness, guilt feelings, tension, suspiciousness, and bizarre thoughts. No significant differences were found between the compared forms of care as regards the degree of other symptoms amelioration. Thus, the day hospital turned out to be a more effective form of care in case of schizophrenic patients manifesting the cluster of symptoms listed above.

[Family burden of patients receiving inpatient treatment or alternative forms of psychiatric care].

Professionals working with chronic patients are usually aware of vast deficitis in what is called in the literature "natural support networks". The deficits generally increase over time, as is the case with broadly defined social skills. Although the efficacy of biological treatment was similar in all the three forms of care, nevertheless, patients and their families, when left without psychotherapeutic support provided to them by the day hospital or community treatment team, at one-year follow-up indicated lack of any satisfactory improvement in many dimensions of their functioning, and in some aspects-even a progressive deterioration.
