Religiousness,religious coping methods,and cognitive test anxiety among African-American college students

This study explored the roles of religiousness and religious coping methods in predicting cognitive test anxiety. A convenience sample of 121 African-American students (97 females and 24 males) ranging in age from 18 to 39 (M_age?=?20.16), attending a historically Black university completed an online questionnaire assessing demographic information, religiousness, religious coping methods, and cognitive test anxiety. Results showed that negative religious coping methods were significant factors in predicting cognitive test anxiety. These relationships may be pertinent for understanding salient factors that influence cognitive test anxiety in African-American college students.     

An investigation of cognitive test performance across conditions of silence,background noise and music as a function of neuroticism

The present study investigates the role of trait neuroticism on cognitive performance under distraction. Seventy participants were given a personality test and then undertook a number of different cognitive tasks in silence, in the presence of popular music and in background noise. It was predicted that performance on a general intelligence test, a test of abstract reasoning, and a mental arithmetic task would be adversely affected by background sounds. It was predicted that neuroticism would be negatively correlated with performance on the mental arithmetic task but only when the individuals were working in the presence of background sound. Stable vs. unstable participant's performance on a mental arithmetic task during noise was significantly higher as predicted. The results provided partial support for the hypotheses and are discussed with respect to previous findings in the literature on personality (particularly introversion–extraversion) and distraction on cognitive task performance. Limitations are noted.     

TDQ-60 – a color picture-naming test for adults and elderly people: validation and normalization data

Word-finding difficulties are usually assessed with picture-naming tests. In this article, we present the TDQ-60, a new test designed to assess acquired lexical access deficits, taking into account semantics and psycholinguistic variables. The article includes three studies. Study 1 describes the development phase of the TDQ-60. In study 2, healthy control participants and individuals with a diagnosis of the semantic variant of primary progressive aphasia were assessed to establish the convergent and discriminant validity of the TDQ-60. Finally, in Study 3, a group of 305 young and elderly French-speaking adults from Quebec were assessed in order to provide normative data. The results demonstrate that the TDQ-60 has good convergent validity and good discriminant validity. This study also provides normative data in which were considered the effect of age and education.The TDQ-60 is a new valid picture-naming test, controlled for psycholinguistic variables and designed to identify the influence of semantics on lexical access in spoken production.     

Dissecting the expanded cognitive reflection test: an item response theory analysis

This study presents a psychometric evaluation of the Expanded Cognitive Reflection Test (CRT7) based on item response theory. The participants (N?=?1204) completed the CRT7 and provided self-reported information about their cognitive styles through the Preference for Intuition and Deliberation Scale (PID). A two-parameter logistic model was fitted to the data to obtain the item difficulty and discrimination parameters of the CRT7. The results showed that the items had good discriminatory power (αs?=?.80 ? 2.92), but the range of difficulty was restricted (βs ranged from ?.60 to .32). Moreover, the CRT7 showed a pattern of correlations with the PID which was similar to that of the original CRT. When taken together, these results are evidence of the adequacy of the CRT7 as an expanded tool for measuring cognitive reflection; however, one of the newer items (the pig item) was consistently problematic across analyses, and so it is recommended that in future studies it should be removed from the CRT7.     

Effects of blood alcohol testing programmes on drinking behaviour among driving crash patients in emergency departments: A cluster quasi-experimental study

This study aimed to evaluate the effectiveness of blood alcohol testing in decreasing the prevalence of current one-month drinkers among road traffic crash patients within emergency departments at one, two, and three months after a crash. A cluster quasi-experimental study was conducted on 600 crash patients who visited one of the emergency departments at 21 hospitals in Udon Thani province, Thailand. The hospitals were categorised into a (i) high-adherence hospital group (≥70% of all patients) and (ii) low-adherence hospital group (<70% of all patients) according to the compliance of blood alcohol testing in their emergency departments. The data were collected by a trained nurse using a structured questionnaire. The primary outcome was the prevalence of one-month current drinkers. We included 600 patients: 291 from six hospitals in the high-adherence group and 309 from 15 hospitals in the low-adherence group. The prevalence of one-month current drinkers significantly decreased in both the high-adherence and low-adherence groups. However, the prevalence of current drinkers at two and three months after a crash was not statistically significant compared to that one month prior to a crash (48.0% to 19.3% and 31.7% to 13.8% in the high- and low-adherence hospital groups, respectively; p < 0.05 from McNemar’s test). The effectiveness of blood alcohol testing in decreasing the prevalence of one-month current drinkers among traffic crash patients within emergency departments was observed to be statistically significant only at one month after a crash, and not at two and three months.

观点采择对内隐刻板印象的影响研究

该研究对大学生在观点采择和控制两种条件下,性别-职业刻板印象的内隐联想测验结果的对比进行实验。研究表明：观点采择策略的干预效果明显,刻板印象的内隐效应在明显地减弱;在性别-职业刻板印象上存在内隐效应,而且没有性别差异,无论在正常情况下还是受到观点采择策略的干预,男女被试均表现出同等的情形,说明内隐刻板印象具有一定的适应性,在内隐的和无意识的水平上观点采择无法完全消除刻板印象;实验证明研究设计的性别-职业刻板印象的IAT纸笔测验版本是可行的。
