视觉空间指令条件下SOAs变化对数字-空间联结编码的影响:来自ERP的证据

采用数字奇偶判断任务,以数字1-9(5除外)及汉字标签(左、右)作为实验材料,在视觉空间任务指令下探讨系统改变SOAs对数字-空间联结编码方式的影响。行为结果发现,SNARC效应以视觉空间编码方式为主,SOA为0ms并未出现SNARC效应; ERP结果发现,物理一致性在早期成分N1上的主效应显著。表明任务指导语影响SNARC效应的编码方式,其本质受词语信息标签加工程度的影响,且对SNARC效应的编码出现早期感觉阶段,SOAs与目标数字的特性影响SNARC效应的产生。     

ERP responses to images of abstract artworks,photographs of natural scenes,and artificially created uncomfortable images

The idea of efficient coding in the visual brain allows for predictions for the processing of various types of images, including certain artworks, natural images and uncomfortable images. Efficient processing is thought to result in lower responses compared to less efficient processing. The efficiency of the processing is suggested to depend on the architecture of the visual system and the properties of the input image. In this study, neural responses were estimated using EEG across the categories of a set of five images of abstract artworks, a set of five photographs of natural images and a set of five computer-generated uncomfortable images. EEG responses to contrast-matched images were found to be lower for the set of five abstract artworks used in the study compared to the set of photographs of natural images, lending preliminary support for the idea that certain abstract artworks, for example the work of Pollock, may be processed efficiently.     

Centrality ratings,forensic relevance,and production frequency: Which one best identifies central and peripheral items?

Production frequency has often been used to identify central and peripheral information, under the assumption that high frequency implies that the item is central. However, no research to date has tested the relationship between centrality and frequency. Participants watched a video of a bank robbery and completed a free recall test, from which frequency for recalled items was computed. Two groups then watched the same video and rated centrality and forensic relevance for each item. Results showed that most, but not all, items with high frequency were rated as central and forensically relevant but that low frequency items were not diagnostic of either item centrality or forensic relevance. Forensic relevance was a better indicator of item centrality than frequency. We concluded that frequency measures should be avoided to determine centrality. Also, if centrality ratings cannot be collected, forensic relevance ratings may be more appropriate for this purpose.     

Good writers,bad Jews: the “Jewish Question” among Hungarian Jewish intellectuals of the interwar period

This paper investigates the perceived place of the Jewish writer in interwar Hungarian Jewish literature. Post-World War I Hungary suffered from the effects of a short-lived communist regime, and the Trianon Treaty by losing two-thirds of its territories and more than half of its population. Though previously Jewish communities had thrived in the country, these events caused resentment that manifested itself in the creation of anti-Semitic laws in 1920. Within this new context, assimilated liberal young Jewish writers posed the question of “what is a Jew,” reflecting on their Jewishness and Hungarianness at the same time and pondering about the value of each. They answered the question in their creative works, where they indirectly explored issues such as whether Jews are able to write Hungarian novels or whether only a Hungarian can do so; whether Jewish Hungarians could write Hungarian Jewish novels; whether Hungarianness and Jewishness are compatible or whether writing literature is preconditioned on identity. Through the lens of Aladár Komlós, this paper examines the way in which liberal and assimilated young Hungarian Jewish writers interpreted their place in Hungarian culture and society within the framework of these questions.     

Meta-analytic evidence for higher implicit affiliation and intimacy motivation scores in women,compared to men

We used meta-analysis to test for gender differences in implicit needs for affiliation/intimacy, assessed via story-coding methods. We included thirty-three effect sizes from 26 publications and 2 unpublished studies, covering a total of 5962 research participants (58% female). Across studies, women scored higher than men in measures of implicit affiliation motivation (d¹ = 0.45, 95%CI = [0.37; 0.53]). This finding was not moderated by the coding system used, gender congruence of the picture cues presented, or correction for protocol length. Men and women did not differ in their implicit needs for power (N = 2493, k = 15, d¹ = −0.19, 95%CI = [−0.44; 0.05]) or achievement (N = 2235, k = 13, d¹ = 0.14, 95%CI = [−0.03; 0.30]).     

双重作业的颜色编码方式对作业绩效的影响

研究探讨了不同颜色编码方式对双重任务操作绩效的影响。实验结果证明：若采用同类颜色编码方式,同时操作的两种作业就会产生结构限制,降低双重任务操作绩效;相反,若采用异常颜色编码方式,将有效地减少双重任务操作的结构限制,使双重任务的操作绩效得到提高。     

Asymptotic learning of alphanumeric coding in autobiographical memory

Studies of autobiographical memory have shown that observed levels of incidental learning are often relatively low. Do low levels of retention result simply from a low learning rate, or is learning also asymptotic? To address this question, it is necessary to trace performance over a large number of learning opportunities, and this was carried out in the context of the recent development of widespread texting behaviour. It was found that memory for the alphanumeric layout of a phone improved as a function of sending approximately the first 500 texts, but then the improvement stopped. The incidence of memory error was incompatible with a simple power-law relation but was modelled closely by an asymptotic relation. It is suggested that this pattern reflects a movement towards automaticity in the primary task which progressively closes down the possibility that incidental learning can occur.     

Efficacy of standard deviational ellipses in the application of criminal geographic profiling

The premise for this study is that the physical and cultural landscape has a deterministic effect on the location and distribution of serial crime. As a consequence, the distribution of linked crime scenes should exhibit a shape and orientation that is consistent with the underlying landscape. Geographic Profiling models that are able to account for these effects will provide more accurate results than those models that do not. Utilizing basic geographic principles of central tendency and spatial diffusion, this research first analyzed the output of circular and elliptical profile models generated for 30 serial burglaries (n = 164) and 67 serial robberies (n = 370) in Baltimore, Maryland between 1994 and 1997. A comparative analysis of the model output reveals that the Standard Deviational Ellipse is significantly (p = 0.000) better able to predict the home location of a serial offender than profiles generated from circles. Next, the relationship between the orientation of elliptical profiles and the mean linear orientation of the corresponding landscape was assessed to reveal a moderate but significant correlation (r = 0.511, p < 0.001). Together, these findings demonstrate that landscape does impact the locations of crime, and is a measurable parameter that can improve the efficacy of geographic profiling.

工作记忆在简单指数乘法等式判断中的作用

选择大学二年级数学系的学生作为被试,要求他们完成控制条件、语音任务、手动任务和随机间隔决策任务条件下的简单指数乘法等式判断任务,实验结果表明：（1）三种次级任务在真假等式判断的反应时上的干扰效应非常显著;（2）三种次级任务显著增加了假等式判断的错误率,但没有显著增加真等式判断的错误率。这说明,语音环路、视空间模板和反应选择成分参与简单指数乘法等式判断,而且真假等式判断具有不同的注意资源需求。
