Two experiments investigated the interpretation of anaphoric noun phrases, and in particular those thatcould only be linked to their antecedents via knowledge-based inferences. The first experiment showed that much of the inferential processing was carried out as the anaphoric noun phrase was read, although there was some indication that inferential processing continued to the end of the clause. The second experiment attempted to establish why anaphoric noun phrases that are more specific than their antecedents cause problems. It showed that the difficulty did not lie in adding the extra information carried by the anaphor to the representation of the referent. Rather, we suggest, putting extra information in the anaphoric noun phrase disrupts the process of linking that noun phrase to its antecedent.  相似文献

The heterosexual nature of the HIV epidemic in Lothian is such that a number (50 to date) of babies have been born to women who have HIV. Some have needed social work services such as Children Centre placement, foster parents or adopters. Since this work began in 1986, our understanding of the transmission and manifestation of HIV infection in children has grown. However, it is still not possible until children reach the age of two to be certain whether or not they have been infected, or what the outlook is for them. Even then there are some further areas of uncertainty. We have developed a programme of preparation, training and support which has enabled a number of families to live with this uncertainly in offering placements to children at risk of HIV infection.  相似文献

Residents in juvenile residential treatment facilities (JRTFs) often display various emotional, behavioral, and educational needs. Researchers have recently developed behavioral interventions to increase residents' appropriate behavior such as cooperation with facility staff instructions, accepting feedback from facility staff, and tolerating unpleasant events. However, there is not a generally accepted tool for assessing the operant function of residents' problem behavior in JRTFs. For various logistical reasons, indirect functional assessments may be more appropriate in a JRTF than manipulating either antecedent or consequent events. This study obtained scores on the Questions About Behavior Function (QABF) assessment for 17 residents from two dormitory staff members for each resident. To increase the number of respondents, each resident completed a QABF for their own behavior. Results revealed moderate to high correspondence (i.e., agreement) for highest and lowest potential operant function of problem behavior between combinations of JRTF staff and residents. These preliminary findings suggest additional research with the QABF in JRTFs is warranted.  相似文献

Interruption and redirection (IR) procedures involve systematically disrupting an undesirable behavior and prompting an individual to engage in an alternative behavior. These procedures have been frequently assessed for reducing repetitive behaviors for autistic individuals. The primary purpose of this review was to assess IR interventions to determine whether outcomes vary according to intervention characteristics, dependent variable types, design quality, or publication status. A secondary purpose was to assess the extent to which generalization and maintenance outcomes were measured and whether characteristics of these conditions were related to outcomes. IR interventions were moderately successful for reducing repetitive behaviors but less effective for improving corollary variables such as appropriate vocalizations and functional engagement. Generalization and maintenance outcomes, when measured, were poor. Results indicate the need for alternative or augmentative procedures that focus on engagement in meaningful interactions and activities.  相似文献

A laboratory experiment by U.S. public health researchers Hall et al. claimed to demonstrate that a graphic picture-and-text warning label placed on so-called sugary drinks would substantially reduce parents' purchase of them for their children. Hall et al., however, misclassified the alleged “sugary drinks,” omitting those containing natural but equally harmful sugars such as fructose in fruit juice and lactose in milk. They also implied that artificially sweetened “non-sugary” drinks are harmless when available research indicates otherwise. The experiment was further invalidated by the fact that warning labels are illegal in the U.S., and those that Hall et al. used would not be permitted in any case because they partially obscured the manufacturer's brand label. There were many other methodological problems with Hall et al.'s experiment, among them the failure to do what any competent consumer researcher would do—namely ask the parents afterwards why they made the choices that they did.  相似文献

A content analysis of the fiction stories in seven national women's magazines revealed that the primary problem for most of the main characters is romantic. Most of the characters are atractive, single, white Americans younger than 45. They live in the city, have zero to two children, are middle class, and college educated, and they have careers or jobs. Less than half of them are able to solve their own problems, and occupations are assigned sterotypically by gender. The conclusion drawn is that the fiction in these magazines is, in many ways, as traditional as has been found in the past.  相似文献
