Behavioral treatment of thunder and lightning phobias.

The use of four different behavioral techniques in the treatment of six female clients with thunder and lightning phobia is described. The techniques (Systematic desensitization. Covert reinforcement. Stress inoculation training, and Self administered desensitization with tape recorder) were evaluated in single-case experimental designs, using both self-report, behavioral, and physiological data.The immediate and follow-up results showed that five of the clients were completely recovered and the sixth markedly improved after their respective treatment (10–14 session). These results and the questions concerning continuous assessment in single-case design and external validity of laboratory assessment in phobic conditions are discussed.     

Effect of thought-stopping on thoughts,mood and corrugator EMG in depressed patients

The immediate effects of thought-stopping applied to depressive thoughts were compared to those of a control procedure in a group of depressed psychiatric day-patients. Thought-stopping had only a weak effect on average in reducing the frequency of depressive thoughts, and no significant effects on depressed mood or corrugator EMG. A small significant effect on anxious mood appeared related to non-specific factors. The results raise the possibility that thought-stopping may have little specific effect in reducing the frequency of unwanted thoughts. Corrugator EMG was significantly related to the frequency of spontaneously occurring depressive thoughts both between and within subjects.     

Traits attributed to stuttering and nonstuttering children by their mothers

Traits attributed to 34 stuttering and 34 nonstuttering male children by their mothers using an adjective checklist were studied. Mothers of school-aged male stutterers were found to perceive their children as being more insecure, sensitive, anxious, withdrawn, fearful, and introverted than did mothers of nonstutterers. It was concluded that although research has not demonstrated a characteristic stuttering personality, stutterers continue to be perceived as having characteristic personality patterns.     

Aphasia type and aging

We analyzed the relationship between age and clinical type of aphasia in 167 right-handed men who had suffered cerebrovascular accidents. Patients with unequivocal diagnoses as Broca's, Wernicke's, anomic, conduction, and global aphasics were considered. The median age of the Broca's group (51 years old) was significantly lower than that of the total group (55.8 years old), while the median age of the Wernicke's group was significantly higher (63 years old). Moreover the incidence of Wernicke's aphasia increased steadily with age, while incidence of the other types of aphasia peaked in the sixth decade and then diminished with increasing age.     

Stuttering following brain damage

This paper describes the neurological, language, and speech status of seven brain-damaged patients with symptoms of cortical stuttering. We compare data from our seven patients to data presented on other brain-damaged stutterers, review theories of cortical stuttering's etiology, advance alternative hypotheses about mechanisms underlying such dy sfluencies, and compare cortical stuttering to stuttering in childhood.     

Cerebral asymmetry in infants.

This paper examines the intercorrelation matrix of the subtests of the Porch Index of Communication Ability using a variety of factor analytic and rotational procedures. In addition to a general factor reflecting overall language dysfunction, verbal, graphic, and gestural factors were also found which accounted for 83% of the total variance. These factors were related to Schuell's Howes', and Wepman's models of aphasia. The impact of factor analytic methodology on the conclusions drawn from the same data was also examined and suggestions for clinical use of this battery were discussed.     

Computer tomographic localization, lesion size, and prognosis in aphasia and nonverbal impairment.

Computerized tomography scans (80) were used to localize infarcts in 70 patients. Twenty-three aphasics were scanned within 35 days from onset, 39 beyond a year, and 18 were nondominant cases. Aphasics were also grouped according to test scores obtained within 35 days of scan. Chronic global aphasics have larger lesions than persisting Broca's aphasics. The area of persisting Broca's aphasia is similarly anterior but larger than that of recovered motor aphasia. Anomic aphasics evolve from Broca's and Wernicke's types with differing localization. Lesion size correlated with severity and recovery, and comprehension among the subtests.     

Shift of visual field preference for English words in native Hebrew speakers.

Lateralization for visual verbal material was tested with Hebrew and English stimuli presented to Israeli adolescents in their second, fourth, and sixth years of study of English as a second language. Seventy-two children, 12 male and 12 female subjects in each class, were tested by means of a target-word recognition task. Laterality scores derived from reaction-time measures resulted in: (1) a left visual field preference for the English stimuli in the youngest group which decreased with increasing age, becoming a right visual field preference in the oldest group, and (2) a significant and equal right visual field preference for Hebrew stimuli for all groups. The data suggest right hemisphere involvement in acquiring the reading skills of a new language.     

A study of spelling in aphasia

To secure systematic information on spelling abilities following damage to the dominant hemisphere, a test probing performance in three modalities of response was administered to a group of aphasic patients. Except for a predictable deficit among anterior aphasics in oral spelling, anterior and posterior aphasics exhibited comparable performances on the measures of spelling. However, anterior and posterior aphasics differed from one another on the kinds of words they most accurately spelled, the errors they were prone to make, and certain strategies which they characteristically adopted. These results suggest two alternative approaches to spelling: one approach, common in posterior aphasics, entails choosing letter combinations on the basis of their customary sounds; a second approach, common among anterior aphasics, appears to rely on a partially preserved image of the word's appearance.
