Approximately 30% of individuals diagnosed with autism spectrum disorder (ASD) fail to develop vocal communication and, therefore, use some form of augmentative or alternative communication system. The current study replicates and extends previous research on teaching “Who?” and “Which?” mands for information to 3 young children diagnosed with ASD using a speech generating device. Procedures were evaluated using a multiple baseline across participants design. All participants learned to mand for information and, subsequently, used the information to access preferred items. 相似文献

Previous research varying the trustworthiness of appearance has demonstrated that facial characteristics contribute to source memory. Two studies extended this work by investigating the contribution to source memory of babyfaceness, a facial quality known to elicit strong spontaneous trait inferences. Young adult participants viewed younger and older babyfaced and mature-faced individuals paired with sentences that were either congruent or incongruent with the target??s facial characteristics. Identifying a source as dominant or submissive was least accurate when participants chose between a target whose behavior was incongruent with facial characteristics and a lure whose face mismatched the target in appearance but matched the source memory question. In Experiment 1, this effect held true when older sources were identified, but not own-age, younger sources. When task difficulty was increased in Experiment 2, the relationship between face?Cbehavior congruence and lure facial characteristics persisted, but it was not moderated by target age even though participants continued to correctly identify fewer older than younger sources. Taken together, these results indicate that trait expectations associated with variations in facial maturity can bias source memory for both own- and other-age faces, although own-age faces are less vulnerable to this bias, as is shown in the moderation by task difficulty. 相似文献

The goal of the present study was to determine whether a web-based medium is an effective tool for supporting knowledge, attitude, and behavior change in teachers of elementary school children with attention-deficit/hyperactivity disorder (ADHD). Nineteen teachers from Nova Scotia, Canada completed a 7-week intervention that consisted of presentations, web links, and discussion board activities related to different aspects of ADHD. Teachers' knowledge positively changed from pre- to post-intervention (p = .03), as did teachers' attitudes related to perceived control in their classrooms (p = .001) and competence in teaching (p < .0001). The study demonstrated that a web-based medium is a useful tool for knowledge creation and translation and has potential as a means of providing professional development to teachers about ADHD. 相似文献

The status of women in the United States varied considerably during the 20th century, with increases 1900–1945, decreases 1946–1967, and considerable increases after 1968. We examined whether changes in written language, especially the ratio of male to female pronouns, reflected these trends in status in the full text of nearly 1.2?million U.S. books 1900–2008 from the Google Books database. Male pronouns included he, him, his, himself and female pronouns included she, her, hers, and herself. Between 1900 and 1945, 3.5 male pronouns appeared for every female pronoun, increasing to 4.5 male pronouns during the postwar era of the 1950s and early 1960s. After 1968, the ratio dropped precipitously, reaching 2 male pronouns per female pronoun by the 2000s. From 1968 to 2008, the use of male pronouns decreased as female pronouns increased. The gender pronoun ratio was significantly correlated with indicators of U.S. women’s status such as educational attainment, labor force participation, and age at first marriage as well as women’s assertiveness, a personality trait linked to status. Books used relatively more female pronouns when women’s status was high and fewer when it was low. The results suggest that cultural products such as books mirror U.S. women’s status and changing trends in gender equality over the generations. 相似文献

Although the law assumes a close relation between the probability that a defendant committed the act in question and the ensuing verdict of the jurors, prior research has shown this assumption to be often violated. We present five experiments designed to show that factors that influence probability also influence verdict, but other factors are capable of directly producing changes in verdict without affecting probability. In Experiment 1, we replicated the Wells Effect; scenarios generating the same probability that the Blue Bus Company was to blame for the same accident, nevertheless, generated significantly different likelihoods of finding the defendant liable. In Experiment 2, we showed that equally diagnostic affirmative and negative evidence had differential effects on mock jurors' probability estimates and verdicts. In Experiment 3, we showed that a completely nondiagnostic witness, who either implicates the same bus company or a different bus company as did a diagnostic witness, significantly influenced mock jurors' verdicts. However, the nondiagnostic witness did not change the probability that the Blue Bus Company was responsible for the accident. In Experiment 4, we demonstrated that base rate and witness reliability information resulted in very similar probability estimates but radically different verdicts. In Experiment 5, we showed that a change in the diagnosticity of the evidence influenced both probability and verdict with the former mediating differences in the later. Because probability is only one of the several determinants of the verdict, the two dependent variables are not as closely related as the law presumes. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

Prevailing theories of judgmental contrasts propose mechanisms ranging from relatively low versus high degrees of thought. The present research tests the hypothesis that the degree of thought involved in producing judgmental contrast has important implications. In three experiments, participants' ability or motivation to engage in effortful thinking was manipulated. In Experiment 1, varying personal relevance produced equivalent contrast effects, but these judgments differed in certainty. In two additional studies, despite equivalent amounts of contrast, a manipulation of the order of the standards and target of comparison led to differences in certainty (Experiment 2) and attitude–behavioral intention correspondence (Experiment 3). This is the first research to show that amount of thinking has implications for the strength and consequences of the judgment. 相似文献

To date, research investigating the similarity among lineup members has focused on adult eyewitnesses. In the present research, children made identifications from lineups containing members of lower or higher similarity to a target person. In Experiment 1, following a live interaction, children's (6–14 years) correct identification rate was reduced in higher‐similarity relative to lower‐similarity lineups. In Experiment 2, children (6–12 years) and adults watched a video containing a target person. Again, higher‐similarity lineup members reduced children's correct identifications; however, similarity had no effect on adults' correct identification rate. Although children benefited from lower‐similarity lineups when the target was present, lower‐similarity lineups generally increased misidentifications of an innocent suspect when the target was absent. Thus, increasing similarity in lineups for children had a cost on target‐present lineups and a benefit on target‐absent lineups. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献
