Maternal directiveness, assessed by the mother's use of prescriptives, is correlated with slow vocabulary development. As prescriptives are most often used to redirect a child's attention to a different object or activity, it is hypothesized that attentional regulation underlies this negative relationship. In the present study, twelve mothers were(More)
20 3-month-old infants participated in a nonsocial contingency task immediately following a social interaction with their mothers. A measure of the time the dyads spent in a state of vocal turn-taking predicted individual differences in the infants' subsequent performance on the contingency task. These results parallel the social transfer effects we(More)
Two-, 3-, and 4-year-old children viewed 10 stimulus sets. Each set contained a sample picture (e.g., a dog), a basic-level taxonomic match (e.g., another dog), a thematic match (e.g., a bone), and an irrelevant match (e.g., a pen). The children were asked to choose a match that "goes with" each sample. Sample pictures were either animate entities or(More)
The hypertrophic aspect of tissue after endoscopic papillotomy may suggest the diagnosis of a small periampullary tumor. In our experience of 55 periampullary carcinomas, the diagnosis was confirmed histologically in 50% of the cases before endoscopic papillotomy and in 100% of the cases when the biopsies were performed immediately after papillotomy. With(More)
Ten patients with unresectable esophageal malignant tumor have been managed by Nd-YAG laser palliative therapy. Esophageal obstruction, and dysphagia, the most frequent symptoms, were relieved in all cases after periods ranging from 5 to 14 days. The mean total energy required was 26.121 watts sec-1. No serious immediate or late complication was(More)
The interest of morphologic investigations in the diagnosis, the prognosis and the treatment of acute pancreatitis was analyzed in a series of 120 patients. The systematic endoscopy of the biliary tract yields a distinction between the biliary and the non-biliary sources of pancreatitis and can be followed immediately by an endoscopic sphincterotomy. Th(More)
Percutaneous cholecystostomy is an expanding technique since the use of ultrasonography permits a precise puncture of the gall bladder. Cholecystitis is a classical complication of endoscopic maneuvers in the biliary tract or can be associated with obstructive jaundice. Following their results the authors conclude on the usefulness of percutaneous(More)
3 experiments with 3-month-old infants compared the effects of contingent and noncontingent adult-infant social interactions on subsequent infant-controlled habituation and choice tasks. Infants who experienced a prior noncontingent social interaction tended to adopt response strategies that reduced the density of stimulation during these subsequent(More)
