This study investigated daily states and time use patterns associated with depression. Four hundred eighty-three 5th to 9th graders reported on their experience when signalled by pagers at random times. Depressed youth reported more negative affect and social emotions, lower psychological investment, lower energy, and greater variability in affect. These differences were weaker for 5th and 6th graders, suggesting that self-reported feeling states are a poor indicator of depression prior to adolescence. No differences were found in the daily activities of depressed youths nor in the amount of time spent alone, but depressed youths experienced other people as less friendly and more often reported wanting to be alone, especially when with their families. They also spent less time in public places and more time in their bedrooms. Finally, depressed boys, but not girls, spent much less time with friends, particularly of the same sex, suggesting that social isolation is more strongly associated with depression for boys.  相似文献

The essay examines the argument advanced by E.D. Hirsch, Jr., for instituting ‘cultural literacy’ as a fundamental priority of schools. A number of confusions and equivocations in Hirsch's reasoning are identified, and the propensity of his project to indoctrinate is exposed. Among the features of Hirsch's argument shown to be troubling are his shifting construal of ‘language’, his inconsistency about the requirements of cultural literacy, and his uncritical relation to traditional images of the American past and present. The upshot is to raise the question why Hirsch's project has elicited wide support and praise.  相似文献

The response of lay persons to pseudostuttering in approximately 200 spontaneous communication situations were reported and evaluated by 24 graduate students in an advanced class in fluency disorders. The students each spent a day as a “stutterer” in all speech contacts. They summarized their pseudostuttering efforts, the perceived auditor reactions, and their own feelings, in each situation. Results indicated that most lay reactions to any stuttering behavior were, at best, neutral or characterized by obvious changes in behavior. Many reactions were overtly and strongly negative. Student reactions were consistently ones of anxiety, fear, the desire to avoid, frustration, and irritation. Feelings of anger and humiliation were common. Discussion of results points out the value of pseudostuttering experience in clinician training, the possible importance of attitude and adjustment consideration in management of clients who stutter, and the apparent failure of (and need for) our profession to educate the lay public about communicative disorders.  相似文献

How can we explain that an assertion on something perceived can be understood in the same manner by somebody who cannot perceive that scene? This problem bases the interest in computational linguistics in how listener modeling could possibly be harmonized with reference semantics. Mental images substituting real perception appear as a way out. The architecture of the listener model has to be adapted to the creation and use of such pictorial data structures. Furthermore, the relation between the latter and a verbal (i. e., propositional) representation must be understood. The resulting architecture of a listener model with reference semantics can be employed to solve communicational problems from three general classes in a better way, as is demonstrated by an example implementation.  相似文献
