Acquired aphasia with convulsive disorders in children: a case study with a seven-year follow-up.

In a 7-year follow-up a case of the “syndrome of acquired aphasia with convulsive disorder” is described. In particular, attention is paid to EEG patterns and linguistic analysis. Although seizures have been controlled medically and EEG abnormalities have tended to improve, no close parallel improvement has been observed in the patient's language disorders.     

Extraversion and the orienting reaction habituation rate to visual stimuli

Eysenck's (1967) proposal that introversion is characterized by increased levels of activity in the cortico-reticular loop was treated in a series of experiments which compared high, middle, and low extraversion groups on the basis of OR habituation rate to visual stimulation. Generally, introverts were observed to have longer OR habituation rates to chromatic and word stimulation than extraverts as evidenced by cardiac, electrodermal, and vasomotor indices of habituation rate, a result which endorses Eysenck's hypothesis. Results are also discussed from the standpoint of individual differences in autonomic response.     

The effects of didactic classroom instruction versus field exposure on career maturity

This study tested two types of career training (field exposure and didactic classroom) to determine which is more effective in bringing about the development of career maturity. Forty-six first-year Upward Bound students were assigned to either a field exposure or a didactic group by the use of a stratified random assignment technique. A pretest/post-test design was utilized with the Career Maturity Inventory as the data-collecting instrument. The data were analyzed by analysis of covariance. The results of the study indicate that field exposure career training is an effective method to increase career maturity.     

A shortened version of the Southern Illinois university speech situation checklist for the identification of speech-related anxiety

This study investigated the ability of the 51-item Southern Illinois University Speech Situation Checklist (SSC) to differentiate stutterers known to have high levels of speech-related anxiety from nonstutterers with normal levels of speech- related anxiety. Checklist responses of 65 randomly selected subjects (33 stutterers and 32 nonstutterers) were subjected to a stepwise discriminant analysis. The analysis identified a combination of 21 SSC items that had significant discriminative power. Subsequently, the derived discriminant equation achieved 93% accuracy in correctly classifying a hold-out sample of 29 subjects (14 stutterers and 15 nonstutterers). These results strongly suggest that the 21 items of the SSC identified by discriminant analysis may provide an effective screening device for identifying disfluent speakers who experience an abnormal amount of speech-related anxiety.     

Alexia and agraphia with spared spelling and letter recognition abilities

A patient with alexia and agraphia had intact spelling and comprehension of spelled words and used a letter-naming strategy to read and write. We propose that there is a graphemic area important for distinguishing graphemic features and for programming movements used in writing. In this patient this area was not functioning or did not have access to the area of visual word imagés. Therefore, he used an ideographic letter-naming strategy to verbally circumvent his disability and gain access to the area of visual word images.     

A prospective naturalistic study of the impact of an intensive medical treatment on the social behavior of child and adolescent cancer patients

The impact of intensive chemotherapy and prolonged hospitalization on the social behavior of child and adolescent cancer patients was assessed. Twenty-three patients, aged 18 months to 21 years, were observed while they received chemotherapy in a protected environment or in a regular hospital room. Single-subject analyses were used to examine changes on six behaviors in relation to changes in physiological status. Fourteen patients showed significant change in the frequency of at least one behavior. Play and sleep were the behaviors most likely to change. The changes began to occur as patients experienced the systemic toxic effects of the drugs, although a dissipation of drug toxicity generally was not accompanied by a corresponding behavior change. The findings are discussed in relation to age-developmental and interindividual heterogeneity in response to treatment.     

Operant baseline procedures suppress infant social behavior

Two groups of six 3-month-old infants participated in a study which contained four consecutive 2-min periods. During Periods 2 and 4 both groups received adult social stimulation on the same prearranged schedule. The treatments during Periods 1 and 3 differed between the two groups; no adult was present for the A-S group, while the B-S group received the typical operant baseline (unresponsive adult treatment) for these two periods. Social stimulation caused a significant increase in vocal rate from the preceding control period for both groups. Infants in the A-S group vocalized at the same rate during the two periods in which the adult was absent and at similar rates during the two stimulation periods. For infants in the B-S group, baseline procedures suppressed vocal rates and did not provide a neutral or operant level of responding with which the effects of social conditioning could be compared.     

Ear asymmetries on a selective attentional task

To ascertain whether there are ear-hemisphere asymmetries of selective attention, signal stimuli (tonal sequences) were presented monaurally with and without complex maskers (music and speech). The right ear-left hemisphere was more disrupted by language maskers; the left ear-right hemisphere was more disrupted by music maskers. These results suggest that there are hemispheric asymmetries of selective attention and that the ear hemisphere that usually processes a class of stimuli has greater difficulty filtering out those stimuli than does the nonspecialized hemisphere.
