视觉负后像对视觉搜索效率的干扰效应

为了探究视觉负后像对视觉搜索效率是否会通过颜色这一特征产生干扰,结合Van Lier后像和视觉搜索范式,通过两个实验考察了负后像对视觉搜索效率的干扰效应,并对负后像填充区域和原始发生区域进行了对比。实验结果表明,在有负后像的情况下,视觉搜索效率明显降低,但是不同颜色之间的差异并不显著;而负后像填充区域的干扰效应要弱于原始发生区域。研究结论对于进一步提高视觉搜索效率的颜色设计以及视觉负后像的新研究方法具有重要的参考意义。     

Suicide Signs on the Rorschach

This paper reviews the literature concerning the assessment of suicide using the Rorschach and updates the important developments since Goldfried, Stricker, and Weiner's comprehensive review of the literature in 1971. Special attention is given to those indicators which show the most support in the literature and are most efficient to use. The presence or absence of any of these signs in a patient's record should not be taken to signify the presence or absence of suicidal ideation. However, the presence of even one of these indicators does provide a warning to the clinician, indicating that further exploration in this area may be warranted. Knowledge of the many suicidal indicators on projective tests places the clinician in a better position to predict such destructive behavior and intervene appropriately.     

Being white,being Jungian: implications of Jung’s encounter with the ‘non-European’ other1

This personal account charts the changing relationship to a Jungian identity arising from the interrelated processes of understanding the roots of the colonial and racial ideologies that underpin Jung’s thinking, and a developing awareness of what it means to be a white person in a system of racism that maintains white supremacy. This is illustrated with reference to the image of a black man appearing in the dream of the white author and with use of post-Jungian thinking to critique the notion of an objective, non-racial psyche.     

Applications of social cognitive theory to the career development of women of color

This article provides a review of the literature on the educational and career development of women of color within the context of social cognitive career theory (Lent, et al, 1994 and Lent, et al, 1996). Specifically, possible gender, ethnic, racial, and cultural influences on career self-efficacy and outcome expectations are explored to delinate the potential mechanisms whereby ethnicity, culture, and ethnic and racial identity development, in interaction with gender, affect career choice and adjustment. Suggestions for future research on social cognitive career theory and the career development of women of color are presented.     

The Influence of Color on Brand Extension: Mediation Role of Processing Style

Color carries distinct psychological meanings and thus it may induce a different cognitive processing style. Adopting this conceptual framework, the current research investigated the influence of color on brand extension evaluation. For color manipulation, participants were given the picture of a brand extension product (e.g., notebook) on a blue versus red background on a sheet of paper. Then participants evaluated the brand extension product. The finding revealed that participants in the blue-background condition evaluated the extension product more favorably than those in the red-background condition. This research further demonstrated that processing style mediated the effect of color on the evaluation of the brand extension product by using a visual matching task. In addition, this research showed the moderating effect of brand slogan on brand extension evaluation. Participants in the blue-background condition evaluated the extension product (i.e., digital camera) more favorably when they were exposed to the abstract brand slogan, whereas participants in the red-background condition evaluated the extension product more favorably when they were exposed to the concrete brand slogan.     

Association between synesthetic colors and sensitivity to physical colors changed by type of synesthetic experience in grapheme-color synesthesia

Grapheme-color synesthesia is a condition in which visual perception of letters induces simultaneous perception of a specific color. Previous studies indicate that grapheme-color synesthetes are more sensitive to physical colors than non-synesthetes. Synesthetic colors are found to be concentrated in multiple regions of the color space, forming “synesthetic color clusters”. The present study investigated whether color sensitivity corresponding to synesthetic color clusters (clustered colors) is higher than color sensitivity that does not correspond to synesthetic color clusters (non-clustered colors). However, we found no difference in the color sensitivity for clustered and non-clustered colors. We also investigated whether the color sensitivity is dependent on the synesthetic experience (associators and projectors). We found that the greater the tendency toward associator characteristics, the greater the sensitivity for clustered colors compared to that for non-clustered colors. Our findings suggest an association between synesthetic colors and physical color sensitivity that is modulated by synesthetic experience.     

非目标工作记忆表征下颜色关联和抽象关联的注意捕获和抑制

采用工作记忆—视觉搜索双任务范式,探讨在非目标工作记忆表征下,颜色关联和抽象关联干扰子的注意捕获和抑制现象。实验1结果发现,颜色关联干扰子在快速反应阶段捕获注意,随后被成功抑制;抽象关联干扰子仍能捕获注意。实验2消除知觉凸显后,结果发现颜色关联条件的抑制消失,干扰子重新捕获注意。结果表明,有效抑制策略受不同关联干扰子加工先后顺序的影响,选择性抑制颜色关联干扰子,而颜色特征的凸显有助于抑制策略形成。     

Number perseveration in healthy subjects: Does prolonged stimulus exposure influence performance on a serial addition task?

Perseverative behavior characterizes mainly patients with severe psychopathology, but it can also be observed in healthy individuals. The aim of the reported experiment was to investigate a serial addition task that elicits strong perseverative behavior in normal subjects by examining the significance of perseveration in the final step of this addition task (Gardner, 1971) as a function of time availability. The classical serial addition task, which was used in the experiment, consisted of 4 consecutive digit decreases in the added numbers following a constant digit (1,000 + 40 + 1,000 + 30 + 1,000 + 20 + 1,000 + 10) and required an additive calculation. The main questions were how and if color and time variations could influence perseverative responses in this task and whether memory performance and relevant mathematical knowledge of the participants could have an effect on responses. The sample of subjects participating in the experiment consisted of 300 healthy university students (112 male, 188 female) ranging from 17 to 40 years of age. They were divided in 5 groups of 60 subjects each. A memory digit span and spatial test were administered and relevant scores were taken for each subject of the 5 groups. Obtained results suggest the presence of a strong perseverative error in the final step of the presentation of digits for the large majority of subjects and for all 5 conditions. It seems that time and color changes and the memory span of the participants have no detectable effect on performance on this specific serial addition task.     

Japanese north–south gradient in IQ predicts differences in stature,skin color,income, and homicide rate

Regional differences in IQ are estimated for 47 prefectures of Japan. IQ scores obtained from official achievement tests show a gradient from north to south. Latitudes correlate with height, IQ, and skin color at r = 0.70, 0.44, 0.47, respectively. IQ also correlates with height (0.52), skin color (0.42), income (0.51) after correction, less homicide rate (− 0.60), and less divorce (− 0.69) but not with fertility infant mortali'ty. The lower IQ in southern Japanese islands could be attributable to warmer climates with less cognitive demand for more than fifteen hundred years.     

Defect formation in Nd2Fe14B grains caused by Zn diffusion

Defect formation in Nd₂Fe₁₄B grains, caused by a low-pressure-pack-sublimation Zn coating process, has been investigated. The results indicate that, in the Zn-affected region, low-angle boundaries decorated with precipitates form within the Nd2Fe14B grains. Zn, which is almost insoluble in Nd₂Fe₁₄
