The Orthodontic Attitude Survey was designed to assess children's and their parents' attitudes toward malocclusion and orthodontic treatment. Five consistent clusters of attitudes had discriminant validity, and were significantly related to plans for orthodontic treatment and to objective and subjective indicators of the child's occlusal status and appearance.
A variation of concept-scale interaction in the semantic differential, labeled concept-component interaction, is discussed. A comparison is made of various methods of analyzing semantic differential data, and an alternative method is introduced which provides evidence of concept-component interaction. Implications for semantic differential measurement are discussed.
This research deals with the relationship between expectancy and attention. In two experiments, expectancy concerning the modality of a probe stimulus was manipulated. In Experiment 1, the frequencies of probes in auditory and visual modalities were varied. In Experiment 2, a cue prior to each trial indicated the relative probabilities of the two types of probes. In both experiments, expectancy effects were observed in a single-task condition during which the subject's only task was to respond to the probes and in a dual-task condition in which probes were inserted in the study phase of a pattern recognition task. If maintaining an expectancy requires attention, then diverting attention from the probe task to the pattern recognition task should have attentuated the effects of expectancy. In fact, the pattern recognition task did not alter frequency effects but did significantly reduce cueing effects. We conclude that expectancy as determined by frequency results from automatic activation, whereas expectancy as determined by cueing involves attention.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
