ABSTRACT: A 12-month study was completed in London, Ontario, Canada, of physician contacts with 232 patients with nonhospitalized self-injuries. Of 254 physicians contacted, 17 percent accounted for the reports of the 232 patients—83 percent of the physicians reporting zero cases. Reasons for underreporting by physicians of nonhospitalized self-injuries, as well as reasons for cases of self-injury being differentially distributed among different kinds of physicians, are explored. The notion of “self-injury” is examined, and some practical implications are discussed. 相似文献

It is suggested that the dominance of observational methods in child language research with very young children has limited progress in understanding the language acquisition process. Evidence is presented that, contrary to popular belief, naturalistic methods do not guarantee ecological validity, nor are they free of task biases. Furthermore, observational studies do not necessarily provide better measures of linguistic competence than do more structured methods. Instead, it is argued that new insights from cognitive developmental research are applicable in studying language production in children younger than 3 years. A number of structured techniques are reviewed that have been used or could be used to study language production. It is concluded that a combination of methods is necessary in order to disentangle and control the many variables that enter into the language acquisition process. 相似文献
