Recent research demonstrated that when autistic children are presented a discrimination task with multiple cues, they typically respond to an abnormally limited number, usually one, of the available cues. This phenomenon, termed "stimulus overselectivity," has been implicated as a possible basis for many of the behavioral deficits characteristic of autism. The present investigation was conducted to systemically analyze the effects of changing the schedules of reinforcement during discrimination training on subsequent stimulus overselectivity. Twelve autistic children were taught a discrimination involving multiple visual cues, with a CRF schedule of reinforcement. The children were then overtrained on either the same (CRF) schedule or on a partial (VR:3) reinforcement schedule. Subsequent overselectivity on single-cue test trials was then assessed. Results suggested that significantly less overselectivity occurred when the children were presented with the VR:3 reinforcement schedule during overtraining. These results are discussed in terms of variables influencing overselectivity and in terms of implications for designing treatment procedures for autistic children.

Food satiation and oral hygiene punishment were used to treat the non-life-threatening rumination of two institutionalized profoundly retarded persons. Satiation consisted of allowing the clients to eat until a satiation criterion of food refusal was achieved or until two full meal portions were consumed. The oral hygiene procedure consisted of cleansing the clients' teeth and gums with Listerine for 2 minutes following each instance of rumination. In the formal study, three conditions--baseline, satiation, and satiation plus oral hygiene--were used following the lunch meal in a multiple-baseline across-subjects design. One client's rumination decreased from an average of 89.5% during baseline to 48.8% during the satiation condition and to 3% during satiation plus oral hygiene. The second client's rumination decreased from a baseline average of 49.9% to 7.9% during satiation and to 1.4% during satiation plus oral hygiene. Generalization probes taken following the breakfast and dinner meals showed a systematic decline in rumination as the various conditions were implemented following the lung meal. In the 16-week follow-up, rumination was treated following all meals with oral hygiene, and satiation was used at one of the daily meals for 1 week on a rotating basis. Rumination remained at a near-zero level following all meals throughout the follow-up. Thereafter, a maintenance program was conducted by the ward staff. The satiation plus oral hygiene punishment treatment program appears to be an immediate, effective, enduring, and humane method of treating the non-life-threatening rumination of retarded individuals.

The literature on various aspects of learning and performance in autistic children is reviewed and interpreted as indicating very little that is specific to autism. Inadequate and inconsistent methodology precludes generalizations concerning the nature of the disorder. It is suggested that future research should be particularly concerned with controlling for developmental influences on performance, and with investigation of the higher functioning autistic children who are less governed by retardation factors. The current evidence is considered to support a hypothesis concerning abnormal hemisphere functioning in this group of children.

Lauretta Bender, internationally known as one of the pioneers in the field of child psychiatry, has written extensively on autism and other forms of childhood disturbance. This paper reviews and analyzes the development of her theories on autism, especially as it relates to childhood schizophrenia. Bender believes that the condition is one of the manifestations of schizophrenia occurring in earliest childhood. This review traces, through her writings and through personal contact, the development and elaboration of this view, and discusses influences on her work of Schilder, Gesell and others.

This paper presents a well-documented case of monozygotic male twins concordant for infantile autism, with a twelve-year follow-up. Assessments include birth records, laboratory studies, physical measurements, psychometrics and quantifiable behavioural ratings by independent raters using multiple scales. Possible aetiological factors of infantile autism, as well as outcome are discussed.

The following case study reports the differential development of autistic symptoms over a 9-year period in a pair of fraternal twins. Neither of the twins developed normally. Evaluations revealed that although the older (male) twin showed some early signs of pathology and suffered from frequent illnesses, he ultimately has developed more normally than his sister, who likely sustained brain damage as a result of perinatal anoxia. Significant improvements has occurred in both cases. Diagnostic, etiological, and treatment implications are discussed.

The problem of differential diagnosis of childhood schizophrenia versus gross brain pathology is a difficult one. The clinical picture, for instance, of dementia infantalis (Heller's Disease) is indistinguishable from that of schizophrenia (Shaw & Lucas, 1970). The same is true of some major metabolic disorders (Bray,1970). Coexisting neurological and EEG findings for seizures are not helpful since these are often seen in schizophrenia (Bender, 1947; Fish, 1977). Mental retardation may coexist with schizophrenia or any of the other disorders. The following is an unusual case illustration of a child presenting symptoms of schizophrenia, seizures, and retardation without neurological abnormalities. Until his gross anatomical brain pathology was found by neurologic evaluation, he was subjected to the inappropriate treatment of psychotherapy.

A pair of monozygotic twins were born 3 weeks prematurely. They were concordant for early infantile autism (EIA) and developed at a similar rate until the age of 4 years, when one of them spontaneously improved. The other twin, who has suffered infrequent epileptic seizures since the age of 6 days, is still grossly autistic. The results of neurological examination and the electro-encephalograms of both are within normal limits. The role of genetic factors in the aetiology of autism is stressed, although these factors were not all important in the further development of these twins.
