A computer interview was developed to collect information about drug use/abuse from high school students. Responses to this interview were compared with those obtained from an identical paper-and-pencil questionnaire given to the same students, in counterbalanced order. Results were comparable for the two methods, but missing data and logically inconsistent answers obtained with the paper-and-pencil questionnaire were not possible with the computer interview. The overwhelming majority of respondents preferred the computer interview as a means of data collection. 相似文献

Abstract. This paper states the author's understanding of the doctrines of the Christian faith in the light of her scientific background and her interpretation of current evolutionary, neuropsychologi–cal, and other scientific theories. It contains the actual ordination vows and her response to them, based upon an outline of questions suggested by the United Church of Christ. 相似文献

Safety belt use on a university campus was substantially increased by offering faculty/ staff and students who signed and returned “buckle up” pledge cards the opportunity to win prizes donated by community merchants. The 28,000 pledge cards, committing signers to buckle up for an academic quarter, were distributed during the spring and fall of 1985. One portion of the card was designed to be hung from a vehicle's rearview mirror as a reminder of the pledge to buckle up. The other portion served as a sweepstakes ticket and was deposited in boxes located throughout the campus community. Each quarter, winners were drawn from the returned pledge cards during three consecutive weeks. Although a relatively small proportion of the pledge cards were signed and turned in (i.e., 11.9% during spring and 9.4% during fall), those who signed and returned a pledge card (n = 3117) increased their safety belt use significantly. Across both quarters, faculty/ staff pledgers went from a high pre-pledge belt use level of 32.2% to a post-pledge level of 46.7%, and students increased their belt use from a pre-pledge use of 21.4% to a post-pledge level of 36.6%. 相似文献

Three experiments were conducted to explore the “automatic” encoding of information about presentation modality and the use of such information during word retrieval. Children (Grades 2, 3, and 6) and adults (college students) were asked to attend to a mixed-modality (auditory and visual) list of nouns, then to recall the target words, and finally to identify the presentation modality of each word on a recognition list. Instructions (incidental vs. intentional), list length, and list organization (unrelated words vs. words from taxonomic categories) were varied across the experiments. Although these manipulations affected the recall of target words, they did not change the amount of modality information retained, which was clearly above chance in all three experiments. As predicted by the Hasher and Zacks (1979) model for automatic processing, there were no developmental changes on memory for modality, instructions to remember modality information had no effect on modality identification, and a tradeoff between word recall and modality identification rarely occurred. 相似文献

Autistic children often do not transfer from extra-stimulus prompts, and thus do not utilize a frequent learning aid. It has been hypothesized that this is due to stimulus overselectivity; a failure to respond to simultaneous multiple cues. This study was designed to determine if autistic children who initially respond only to single cues can be taught a set to respond to two cues and subsequently utilize an extra-stimulus (pointing) prompt. Four autistic children were pretested to determine if they could learn a complex visual discrimination by either trial and error or an extra-stimulus prompt fading procedure. Since they did not, the children were then taught to respond to two cues through a multiple-cue training procedure and subsequently tested to determine if they could now utilize a pointing prompt. Results indicated that while all four children initially did not transfer from an extra-stimulus (pointing) prompt, they did so subsequent to multiple-cue training. The results are discussed in terms of implications for treatment (remediating overselectivity) and in relation to normal child development. 相似文献

The ‘watched pot’ phenomenon — the lengthening of duration experience when one is attentively and perhaps impatiently waiting for some event to occur — was studied in three experiments. In them, each observer attended for a duration of 270 sec to a liquid-containing beaker on an electrical burner. Observers who were told that the experiment concerned time perception (prospective paradigm) reproduced the duration as longer than those told that it concerned visual perception (retrospective paradigm). In the prospective paradigm, reproductions were longer if the liquid did not boil than if it did, and an interruption (task-unrelated questioning) shortened reproductions if the liquid did not boil but had no effect if it did. In the retrospective paradigm, if there was boiling or questioning or both, reproductions were longer than if there was neither. Results have implications for hypotheses about duration experience. 相似文献

Three experiments used a flavor-aversion preparation to demonstrate the occurrence of within-compound associations in various conditioning procedures. In Experiment 1 rats first received two separate two-flavor compounds, each followed by a mild US. They then received one element from one compound paired with a strong US and one element from the other compound nonreinforced. A subsequent choice test of the other two flavors from the compounds revealed that the consumption of each test flavor reflected the conditioning history of the element with which it had been paired. Rats drank less of the flavor whose associate had been paired with the strong US than of the flavor whose associate had been nonreinforced. In Experiment 2 within-compound associations were observed using a similar design in a blocking procedure in which one element from each of the two compounds was conditioned previously. Experiment 3 identified within-compound associations in a procedure where reinforced single element presentations were intermixed with nonreinforced compound presentations, as in a conditioned inhibition paradigm. These results suggest that within-compound associations occur in several important conditioning procedures which use multiple CS presentations. 相似文献

In a study of motor conflict resolution, 20 Ss in each of two groups, designated as high drive (HD) and low drive (LD) according to scores on the Taylor Manifest Anxiety Scale, had to resolve approach-approach (AP-AP), avoidance-avoidance (AV-AV), and double approach-avoidance (DAP-AV) conflicts. The HD group took significantly longer to resolve all three conflicts than did the LD group; however, resolution time for both drive groups did not differ for the AV-AV and DAP-AV conflicts, but was significantly faster for the AP-AP conflict. It was concluded that manifest anxiety was inversely related to performance in complex conflict situations, and several areas of follow up research were indicated. 相似文献
