Older adults represent a rapidly growing segment of the driving population. Although most older drivers are safe, research has shown that this group has more crashes per mile driven than most other age groups. The purpose of the present investigation was to examine the utility of a set of commonly used neuropsychological/cognitive tests in comparison to a newer measure of visual attention (Useful Field of View; UFOV®) in predicting state-recorded, at-fault crashes over the previous five years in a group of older adult drivers. Participants (N = 239) completed tests of mental status, visual attention, memory, and UFOV®. Results show that among all cognitive tests administered, UFOV® was most strongly related to crash involvement, with high levels of sensitivity (86.3%) and specificity (84.3%) at the standard cutoff score of 40% reduction. Practical implications for the assessment of crash risk are discussed. 相似文献

Measures of self-efficacy to use condoms can clarify the barriers to condom use Latinos encounter. A 20-item scale, that differed slightly for men and women, and was based on extensive elicitation interviews, was used in a random digit dial household survey of 1,600 unmarried Latino adults in 10 states with large Latino populations. Self-efficacy was related to condom use for both men and women. Factor analyses revealed five correlated factors: Regular Partner, Impulse Control, Partner Resistance, STD Thoughts, and Condom Discussion. Both men and women reported lowest self-efficacy for impulse control and using condoms with a regular partner. Less-educated men and women had lower self-efficacy to discuss condoms, to manage partner resistance, to use condoms with a regular partner, and to control impulses, but there were few other demographic differences in self-efficacy. The scale can be helpful in the design and evaluation of HIV prevention. 相似文献

Two concentrations each of sodium chloride and sucrose solutions were used as stimuli in a study examining taste adaptation. Twenty subjects were presented a 3-min continuous flow of each taste stimulus over the anterior dorsal tongue surface, and periodically gave magnitude estimates of its intensity. The degree of adaptation was greater for the less concentrated solutions than for the more concentrated ones, but the majority of subjects did not adapt completely to any of the stimuli. This result, which is consistent with other reports from this laboratory, is discussed in terms of individual differences among subjects and in relation to recent taste research based on completely adapted subjects. 相似文献

The present study investigated burst cue discrimination in 3- to 4-month-old infants with the natural speech stimuli [bu] and [gu]. The experimental stimuli consisted of either a [bu] or a [gu] burst attached to the formants of the [bu], such that the sole difference between the two stimuli was the initial burst cue. Infants were tested using a cardiac orienting response (OR) paradigm which consisted of 20 tokens of one stimulus (e.g. [bu]) followed by 20 tokens of the second syllable (20/20 paradigm). An OR to the stimulus change revealed that young infants can discriminate burst cue differences in speech stimuli. Discussion of the results focused on asymmetries observed in the data and the relationship of these findings to our previous failure to demonstrate burst discrimination using the habituation/dishabituation cardiac measure generally employed with older infants. 相似文献

The purpose of this research was to investigate differences in the perception of speakers as a function of their language and sex. Forty-two Italo-Australian and 56 Greek-Australian young people listened to male and female speakers in each of their two languages, using Lambert et al's. (1960) guise method. Results indicated few differences in Italo-Australian subjects' ratings of speakers as a function of language, while Greek-Australian subjects, in general, rated Greek guises more positively than English guises. In addition, Italo-Australian subjects rated female subjects more positively than male speakers irrespective of language, but Greek-Australian subjects reversed this pattern. 相似文献

A model is presented for upgrading school psychology practice in an entire state by raising the level of entry for school psychology certification. A central feature of the plan is that it permits those who currently do not meet the revised standards to participate in a field-based program. This allows them to increase their knowledge and skills so that they may continue to hold positions, but at a higher level of competence. The development of the program, its implementation, and an evaluation of its efforts over a five-year period are presented. 相似文献

A questionnaire about the frequency and effects of different thoughts during heterosexual activity was returned by 66 females and 75 males in a random sample of college undergraduates and graduate students. A high response rate (91%) was obtained, and the male and female respondents were shown to be generally similar in sexual experience. Frequency data confirmed an earlier study of the same population in finding that, during sexual activity, males think more about past sexual experiences and ongoing behavior, while females think more about imaginary experiences. Effects data indicated that these frequency differences occur because females use fantasy more than males to increase arousal, to decrease anxiety about sexual activity, to compensate for less-than-ideal sexual experience, and to enhance even a satisfactory experience. Males, in contrast, use thoughts of real experience more often than females to increase arousal and to control and direct sexual activity. 相似文献

Participants' representations of the concept human were examined to differentiate three types of associations between concepts and their component attributes: the capacity of concepts to cue attributes (attribute accessibility), the capacity of attributes to cue concepts (instance accessibility), and the extent to which attributes are thought of as central to concepts (attribute centrality). The findings provide information about the concept human itself and, more generally, about the functionally distinct roles those different attribute-concept associations play in guiding imaginative thought. College students listed attributes that differentiate humans from other animals, rated the centrality of those attributes, and listed animals that possess those attributes. Other students drew and described extraterrestrials that possessed some of the attributes that were found to vary across those listing and rating tasks. Rated centrality was the most important determinant of an attribute's impact on imaginative generation. When the imagined extraterrestrials were supposed to possess attributes that had been rated as central to humans (intelligence, emotional complexity, or opposable thumbs), participants projected more aspects of human form onto them than when the creatures were supposed to possess less central attributes or when attributes were unspecified. 相似文献

Cued recall of categorized lists was used to examine effects of category structure on the creation of false memories. In three experiments, category members that had not been presented on studied categorized lists were nonetheless recalled by participants. Delaying the category cued recall test (Experiment 1) and priming category members that had been omitted from target lists (Experiment 3) increased the frequency of false recall. All three experiments showed that nonpresented category members that were higher in output dominance were more frequent intrusions. The typicality of category members, however, did not uniquely contribute to the predictability of false recall (or accurate recall) once the contribution of output dominance was taken into account, suggesting that item accessibility (related to output dominance) may be more instrumental than item distinctiveness (related to typicality) in causing certain types of false recall. The results show that created memories in category cued recall are strongly biased by prior category knowledge and can be predicted by the graded structure of categories, particularly in terms of the output dominance of category instances. 相似文献
