The purpose of this study was to examine the relationship between religious observance and tobacco use among a sample of Jordanian youth. Using multistage, random sampling, a cross-sectional survey of middle and high school students was conducted. Of the 950 Muslim students in the study, 32 % were daily tobacco users and 72 % prayed regularly. Frequency of praying was negatively associated with tobacco smoking. Religious observance was found to be strongly associated with tobacco smoking among Jordanian youth. Our results indicate that religion can be a culturally important tool in health professionals’ efforts for tobacco control.  相似文献

This study compares the tendency for numerals to elicit spontaneous perceptions of colour or taste (synaesthesia) with the tendency to visualise numbers as occupying particular visuo-spatial configurations (number forms). The prevalence of number forms was found to be significantly higher in synaesthetes experiencing colour compared both to synaesthetes experiencing taste and to control participants lacking any synaesthetic experience. This suggests that the presence of synaesthetic colour sensations enhances the tendency to explicitly represent numbers in a visuo-spatial format although the two symptoms may nevertheless be logically independent (i.e. it is possible to have number forms without colour, and coloured numbers without forms). Number forms are equally common in men and women, unlike previous reports of synaesthesia that have suggested a strong female bias. Individuals who possess a number form are also likely to possess visuo-spatial forms for other ordinal sequences (e.g. days, months, letters) which suggests that it is the ordinal nature of numbers rather than numerical quantity that gives rise to this particular mode of representation. Finally, we also describe some consequences of number forms for performance in a number comparison task.  相似文献

Factor analytic studies of the 24-item Personal Attributes Questionnaire (Spence & Helmreich, 1978) have reported inconsistent results, and a previous confirmatory factor analysis (CFA) indicated inadequate fit for factors corresponding to Masculinity, Femininity, and Masculinity-Femininity scales. In this research, we used CFA in a college sample (N = 382) to evaluate the 3-factor model, and we revised scales by eliminating 6 misspecified items. The revised model fit well in another college sample (N = 230). We renamed the revised scales Agency, Communion, and Emotional Vulnerability. In relation to Five-factor theory, Emotional Vulnerability and Communion correlated well with Neuroticism and Agreeableness, respectively, and Agency had moderate correlations with Neuroticism, Extraversion, and Conscientiousness. Psychometric results in the context of current theory suggest that Agency (Masculinity) may not be a fully adequate measure of the agency construct.  相似文献

In 3 experiments, participants saw lists of 16 words for free recall with or without a 6-digit immediate serial recall (ISR) task after each word. Free recall was performed under standard visual silent and spoken-aloud conditions (Experiment 1), overt rehearsal conditions (Experiment 2), and fixed rehearsal conditions (Experiment 3). The authors found that in each experiment, there was no effect of ISR on the magnitude of the recency effect, but interleaved ISR disrupted free recall of those words that would otherwise be rehearsed. The authors conclude that ISR and recency cannot both be outputs from a unitary limited-capacity short-term memory store and discuss the possibility that the process of rehearsal may be common to both tasks.  相似文献

Following a pretest, 8 participants who were unfamiliar with algebraic and trigonometric functions received a brief presentation on the rectangular coordinate system. Next, they participated in a computer-interactive matching-to-sample procedure that trained formula-to-formula and formula-to-graph relations. Then, they were exposed to 40 novel formula-to-graph tests and 10 novel graph-to-formula tests. Seven of the 8 participants showed substantial improvement in identifying formula-to-graph relations; however, in the test of novel graph-to-formula relations, participants tended to select equations in their factored form. Next, we manipulated contextual cues in the form of rules regarding mathematical preferences. First, we informed participants that standard forms of equations were preferred over factored forms. In a subsequent test of 10 additional novel graph-to-formula relations, participants shifted their selections to favor equations in their standard form. This preference reversed during 10 more tests when financial reward was made contingent on correct identification of formulas in factored form. Formula preferences and transformation of novel mathematical and stimulus functions are discussed.  相似文献

Tellegen et al. (2003) proposed fundamental changes in MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) scale development by discarding empirical scale development in favor of construct validation via Jackson's (1970) sequential system of scale development. As a result of their efforts, a general distress factor (Demoralization) was identified and 8 Restructured Clinical (RC) Scales were developed. Using 7,330 clinical cases from Caldwell's (1997) data set, in this study, we sought to cross-validate the MMPI-2 RC Scales. Scale homogeneity was confirmed with high alpha coefficients and interitem correlations in the expected range. We also achieved a major objective of reducing interscale correlations. In replicating Tellegen et al.'s principal components analysis, we achieved a high concordance for 6 of the 8 RC Scales. We critically examine these results in light of Jackson's construct validation. We discuss the clinical usefulness of the MMPI-2 RC Scales within the context of current and future research.  相似文献

The elopement of a child with Asperger syndrome was assessed using functional analyses and was treated in two school settings (classroom and resource room). Functional analyses indicated that elopement was maintained by access to attention in the resource room and obtaining a preferred activity in the classroom. Attention- and tangible-based interventions were compared in an alternating treatments design in both settings. Results validated the findings of the functional analyses. Implications for the assessment and treatment of elopement are discussed.  相似文献

Four experiments investigated item and order memory for sequences of seen unfamiliar faces and heard nonwords. Experiments 1 and 3 found bowed serial position curves using the serial reconstruction test of order with faces and nonwords, respectively. Experiments 2 and 4 found limited recency, no primacy, and above chance performance on all items using a two‐alternative forced choice (2AFC) test of item recognition, again with faces and nonwords. These results suggest that the different serial position curves typically found using traditional paradigms for exploring visual and verbal short‐term memory are due to differences in the methods used rather than modality‐specific mechanisms.  相似文献
