Age differences in peripheral letter perception.

The capacities of 96 eight- and nine-year-old children and 96 adults to discriminate letters in the visual periphery were tested. Four-letter arrays were presented at the fixation point or centered 4 degrees to the left or right. Threshold exposure durations were estimated by a method of ascending limits. Analyses of a transformed threshold measure revealed that although children were less able than adults to discriminate letters in all positions, age differences were greatest for peripherally presented arrays. Development specific to the peripheral visual systems seems implicated.

Alveolar rhabdomyosarcoma associated with disseminated intravascular coagulation and a unique factor VIII antigen.

Disseminated intravascular coagulation (DIC) has been described in association with many tumors. We describe a patient with alveolar rhabdomyosarcoma in whom DIC developed with the initiation of chemotherapy. The patient achieved complete remission of his tumor for 14 months. An unusual factor VIII antigen was identified on crossed immunoelectrophoresis that was present at initial diagnosis, disappeared with remission, and returned with relapse of the tumor.

Bone marrow phagocytosis in sarcoidosis.

The phagocytic activity of the bone marrow monocytes and macrophages was studied in 22 patients with sarcoidosis, 28 patients with Hodgkin's and non-Hodgkin's malignant neoplasms, and 14 controls. Although phagocytosis of RBCs and WBCs and platelets were seen in all bone marrow specimens, the activity was considerably increased in some patients with stage I and stage II sarcoidosis. This observation may reflect the presence of an unusual host response to unknown antigens in patients with sarcoidosis.

Treatment experience with nonseminomatous testicular cancer in patients with stage II and stage III disease.

Thirty-eight patients with nonseminomatous testicular cancer were treated with cis-platinum, bleomycin, and vinblastine in combination without a prolonged maintenance phase. Twenty-Six patients with Stage III disease were treated. Seventy-six percent of those patients treated achieved complete remission. At a median survival time of 30 months, no patient who achieved a complete remission has relapsed. Twelve Stage II patients given adjuvant therapy remain free of disease at a median time of 23 months. Markedly elevated serum lactate dehydrogenase levels and massive disease were common findings in the patients who did not achieve complete remission. One drug death occurred secondary to sepsis. Symptoms of depression and anxiety were significant dose-limiting factors in this group of patients.

Natural regulation of rhesus monkey populations in Kathmandu, Nepal. Rhesus monkey groups near Kathmandu, Nepal, show demographic patterns of intrinsic population stability.

In Kathmandu valley, two populations of rhesus monkeys which are totally protected, have shown relatively stable numbers over a period of several years. Population stability within heterosexual troops appears to have been maintained through lower birth rates and slightly higher infant and adult mortality rates than in comparable rhesus populations in India which have been subject to trapping. Although the behavioral and physiological mechanisms by which these demographic changes occur are not known, behavioral observations on these populations suggest several possibilities. These data represent the first indication of possible mechanisms for population regulation in natural rhesus populations.

Left-hemisphere motor dominance in righthanders.

Left-hemisphere dominance for motor programming was tested in two experiments by measuring acquisition and cross-hand transfer of a complex key-pressing skill in righthanded adults. In the first experiment, visual feedback was excluded to insure unilaterality of motor control. Consistent with left-hemisphere motor dominance, males showed faster acquisition with righthand training than with lefthand training and greater transfer from left to right then vice versa; but females exhibited neither asymmetry. To investigate the possibility that females relied on verbal strategies to remember which keys to press and that this prevented them from showing the predicted asymmetries, the need for such strategies was reduced in a second experiment by allowing visual feedback. Although the provision of visual input may have mitigated against motor asymmetries by directly engaging both hemispheres in the task, results showed more rapid improvement in skills with the right hand than with the left for both sexes, extending evidence for left-hemisphere motor dominance to a population including females as well as males.
