Can blindsight be superior to 'sighted-sight'?

DB, the first blindsight case to be tested extensively (Weiskrantz, 1986) has demonstrated the ability to detect and discriminate a range of visual stimuli presented within his perimetrically blind visual field defect. In a temporal two alternative forced choice (2AFC) detection experiment we have investigated the limits of DB's detection ability within his field defect. Blind field performance was compared to his sighted field performance and to an age-matched control group (n=6). DB reliably detected the presence of a small (2 degrees ), low contrast (7%), 4.6c/ degrees Gabor patch with the same space-averaged luminance as the background presented within his blind field but performed at chance levels at the same eccentricity (11.3 degrees ) within his sighted field. Investigation of detection as a function of stimulus contrast revealed DB's ability to detect the presence of an 8% contrast stimulus within his blind field, compared to 12% in his sighted field. No significant difference in detection performance between DB's sighted field and the performance of six age-matched control participants suggests poor sighted field performance does not account for the results. Monocular testing also rules out differences between the eyes as an explanation, suggesting that DB demonstrates superior detection for certain stimuli within his visual field defect compared to normal vision.

On the alleged memory-undermining effects of daydreaming

In three experiments, we examined the memory-undermining effects of daydreaming for (un)related stimuli. In Experiments 1 and 2, we tested whether daydreaming fosters forgetting of semantically interrelated material and hence, catalyzes false memory production. In Experiment 3, we examined the memory effects of different daydreaming instructions. In Experiment 1, daydreaming did not undermine correct recall of semantically interrelated words, nor did it affect false memories. In Experiment 2, we again failed to find that daydreaming exerted memory-undermining effects a. In Experiment 3, no memory effects were obtained using different daydreaming instructions. Together, our studies fail to show appreciable memory-undermining effects of daydreaming.     

适用于多维迫选测验的IRT计分模型

迫选(forced-choice,FC)测验由于可以控制传统李克特方法带来的反应偏差,被广泛应用于非认知测验中,而迫选测验的传统计分方式会产生自模式数据,这种数据由于不适合于个体间的比较,一直备受批评。近年来,多种迫选IRT模型的发展使研究者能够从迫选测验中获得接近常模性的数据,再次引起了研究者与实践人员对迫选IRT模型的兴趣。首先,依据所采纳的决策模型和题目反应模型对6种较为主流的迫选IRT模型进行分类和介绍。然后,从模型构建思路、参数估计方法两个角度对各模型进行比较与总结。其次,从参数不变性检验、计算机化自适应测验(computerized adaptive testing, CAT)和效度研究3个应用研究方面进行述评。最后提出未来研究可以在模型拓展、参数不变性检验、迫选CAT测验和效度研究4个方向深入。     

False recognition in women with a history of childhood emotional neglect and diagnose of recurrent major depression

While previous research has suggested that adults with a history of childhood sexual abuse may be more prone to produce false memories, little is known about the consequences of childhood neglect on basic memory processes. For this reason, the authors investigated how a group of women with a history of childhood emotional neglect (CEN) and diagnosed with recurrent Major Depressive Disorder (MDD) performed on the Deese–Roediger–McDermott paradigm in comparison to control groups. The results indicated that women with MDD and CEN were actually less prone to produce false memories relative to both women with MDD but no CEN and healthy women without MDD and any form of childhood maltreatment. These findings were explained in terms of the inability to extract/retrieve gist memories that support false recognition of critical lures, an explanation that seems to fit well with emerging MRI findings linking childhood neglect to reduced volume of brain regions associated to memory function.     

The Five Factor Model (FFM) among four groups of male and female professionals

The present study examined the differences in personality traits among groups of seasoned professionals A Hebrew shortened version of Costa and McCrae’s [Costa, P. T., Jr., & McCrae, R. R. (1992). NEO-PI-R: Professional manual odessa. Florida: Psychological Assessment Resources] NEO-FFI questionnaire was administered to 236 Israeli male and female doctors, lawyers, clinical psychologists, and artists (mean age = 31.19). Artists were found to be significantly more neurotic than members of the other three professional groups and significantly more open to experience than doctors. Women were significantly more neurotic and extravert than men, regardless of their occupational affiliation.     

Concurrent and incremental validity of three trait emotional intelligence measures

This study explored concurrent and incremental validity of three trait emotional intelligence measures: the Schutte Emotional Intelligence Scale, Multidimensional Emotional Intelligence Assessment, and Trait Emotional Intelligence Questionnaire. A total of 307 participants were drawn predominantly from community and student populations. Concurrent criterion validity of the measures varied depending on whether emotional intelligence (EI) was assessed as a lower, middle or higher level construct, with validity coefficients being larger for the former. In all cases, the Trait Emotional Intelligence Questionnaire was the superior predictor of multiple psychological criteria. At the higher level of assessment, incremental validity beyond (a) age, gender and the Big Five, and (b) the remaining two EI measures, was also superior.
