Revisiting the learning-without-awareness question in human pavlovian autonomic conditioning: Focus on extinction in a dichotic listening paradigm

Numerous studies have indicated that, consistent with current “cognitive” accounts of information processing, human Pavlovian autonomic discrimination acquisition cannot occur without awareness of the CS-US relationship. However, extinction studies have suggested that awareness is not necessary, findings that, in information-processing terms, have been explained by assuming that the processing by the extinction stage is parallel (automatic) rather than serial (controlled). This explanation was tested in an 80-subject study. The first, acquisition phase was a standard semantic differential conditioning arrangement with a 96-db white noise as US, and a “long” CS-US interval of 8 s, with ten trials each of CS+ (paired with US) and CS− (unpaired) trials. In extinction (USs omitted), in order to obtain non-autonomic indices of processing and thereby test the information-processing account of “unaware” autonomic conditioning during extinction, a dichotic listening task was implemented, with the CSs presented in the unattended channel (ear), while the subject had to perform a semantic differential reaction task in an attended-to channel (other ear). In early extinction, the electrodermal response occurring at an interval of 9–15 s after CS onset (i.e., following placement of the US during acquisition) and the finger-pulse-volume response occurring at an interval of 4–11 s after CS onset both showed reliable conditioning, but reaction-time and subjective-report data for the recognized critical words indicated serial rather than parallel processing of the CSs during extinction.     

Dreaming under fire: the psyche in times of continuous stress

Continuous stress and trauma are manifested in dreams, the study of which can expand our knowledge concerning unconscious reactions to trauma and efforts of coping with continuous traumatic situations. In our research we asked people living under continuous threat of rocket attacks to record their dreams and their associations to them during four consecutive weeks. We collected 609 dreams from 44 women and 18 men (age range 14-62). The dreams submitted were analysed according to the Jungian approach in the light of the information and associations presented by the subjects. Full dream series of dreamers from each group were analysed in an attempt to capture the depth-psychological experience of living and dreaming under fire. The most frequent themes found were: ‘concrete vs. symbolic', ‘togetherness', ‘active ego', ‘fear and anxiety', ‘shadow' and ‘personal issue'. The subjects were divided into three age groups. Differences between the occurrences of themes were examined. On the unconscious level our results showed that the adolescents group seemed to be the most vulnerable to the stress situation (preponderance of concrete dreams), the mature adults group was the least influenced by it (preponderance of symbolic dreams and of the ‘personal issue' theme) and the young adults group made the greatest psychological efforts for coping (preponderance of ‘active ego' theme). We noted few anima figures appearing in the men's dreams, while animus figures appeared in the women's dreams. In another study undertaken immediately after one of the recent wars in Gaza we collected dreams of Israelis living in the south of Israel who were under heavy daily rocket attacks, and dreams of Palestinians living in the West Bank. The most significant difference we found between the groups was a preponderance of symbolic dreams among the Palestinians, as opposed to a preponderance of concrete trauma dreams among the Israeli group living on the Gaza border. In both groups we found archetypal symbols of evil. In conclusion, dreams can help us detect emotional distress, even when subjects seem ‘ok'. Early detection and working with dreams can help prevent the severity of delayed PTSD.     

Too great to act in solidarity: The negative relationship between collective narcissism and solidarity-based collective action

Three studies examined the association between narcissistic identification with one’s advantaged in-group and engagement in solidarity-based collective action. Drawing on theory and past research, a negative effect of collective narcissism on solidarity-based collective action was expected. A two-wave longitudinal study (N = 162) found that Polish participants’ narcissistic, but not secure, national identification decreased their willingness to engage in collective action in solidarity with refugees over time. A field study (N = 258) performed during a mass protest against a proposed abortion ban showed that men’s gender-based collective narcissism was a negative predictor of solidarity-based engagement (operationalized as protest behavior and collective action intentions) and this effect was mediated by lowered empathy for women. Finally, a web-based survey (N = 1,992) revealed that heterosexual/cisgender individuals’ collective narcissism was negatively associated with collective action intentions in support of LGBT rights and that this effect was sequentially mediated by increased intergroup anxiety and decreased empathy for LGBT people. Theoretical implications of the present findings, research limitations, and future directions are discussed.     

内群体偏爱与儿童基于贡献的分配公平性:心理理论的调节作用

本研究考察了贡献和内群体偏爱两种分配动机对儿童分配公平性的影响,并探讨了心理理论在其中的作用。通过比较63名6~8岁儿童在不同群体条件下对贡献不同的接受者的分配结果和分配策略的差异,结果发现：（1）在所有群体条件下,儿童都会分配给贡献多的接受者更多的资源,但当外群体成员贡献多且内群体成员贡献少时,儿童也会分配给贡献多的接受者相比于其他群体条件更少的资源,并更多的采用群体关系策略对这一行为作出解释;（2）心理理论能力越高的儿童分配给贡献多的接受者的资源数量受群体关系的影响越小,且使用贡献策略的频率越高,使用群体关系策略的频率越低。这些结果表明6~8岁儿童在资源分配过程中会优先考虑公平动机,且心理理论能力强的儿童更少表现出内群体偏爱。     

Eyewitness identification in simultaneous and sequential lineups: an investigation of position effects using receiver operating characteristics

For decades, sequential lineups have been considered superior to simultaneous lineups in the context of eyewitness identification. However, most of the research leading to this conclusion was based on the analysis of diagnosticity ratios that do not control for the respondent’s response criterion. Recent research based on the analysis of ROC curves has found either equal discriminability for sequential and simultaneous lineups, or higher discriminability for simultaneous lineups. Some evidence for potential position effects and for criterion shifts in sequential lineups has also been reported. Using ROC curve analysis, we investigated the effects of the suspect’s position on discriminability and response criteria in both simultaneous and sequential lineups. We found that sequential lineups suffered from an unwanted position effect. Respondents employed a strict criterion for the earliest lineup positions, and shifted to a more liberal criterion for later positions. No position effects and no criterion shifts were observed in simultaneous lineups. This result suggests that sequential lineups are not superior to simultaneous lineups, and may give rise to unwanted position effects that have to be considered when conducting police lineups.     

歧视知觉对城市流动儿童幸福感的影响：中介机制及归属需要的调节作用

采用整群取样法对选自北京市的1551名流动儿童进行测查, 探讨歧视知觉对城市流动儿童的个体和群体幸福感的影响机制, 即内群体认同和群体地位感在其中的中介作用, 以及不同归属需要下内群体认同和群体地位感的中介作用差异。结果表明：(1)公立学校小学流动儿童的个体和群体幸福感相对较高; 流动男生比流动女生具有较高的生活满意度, 流动女生比流动男生具有较高的群体幸福感。(2)歧视知觉对城市流动儿童的个体和群体幸福感存在直接显著的负向预测作用, 并通过内群体情感认同和群体地位感的中介作用负向预测群体幸福感。(3)不同归属需要下歧视知觉对个体和群体幸福感的作用机制存在差异。在高归属需要组, 歧视知觉对个体幸福感存在直接显著的负向预测作用, 并通过群体地位感和群体幸福感的双重中介消极地影响个体幸福感; 歧视知觉完全通过群体地位感的中介消极地影响群体幸福感。在低归属需要组, 歧视知觉对个体幸福感既存在直接的负向预测作用, 也通过内群体情感认同和群体地位感的中介发挥间接性的积极作用; 歧视知觉对群体幸福感只存在间接的消极影响, 内群体情感认同和群体地位感在其中发挥完全中介作用。这表明, 内群体情感认同和群体地位感在流动儿童歧视知觉与幸福感之间的中介效应受到归属需要的调节影响。     

好人也会做坏事:有限道德视角下的不道德行为

有限道德是指个体在道德判断中固有的局限性,表现在人们外在行为与内在道德观的悖离,它导致无意识的道德偏差.有限道德弥补了理性道德模型在不道德行为解释力上的缺陷.该视角下的不道德行为主要包括:内隐偏见、内群体互惠、沽名钓誉、利益冲突和漠视未来.关于有限道德存有4种理论解释:自利性动机、双重自我、道德褪色和框架效应.未来有关道德决策和不道德行为的研究,需要延伸到有限理性与无意识层面.     

Attribution style and post-traumatic stress severity in the Central Region of Kenya: Influences of dwelling location

This study investigated the influence of attribution styles as predictors of post-traumatic stress severity (PTSS) by dwelling in Kenya. A non-clinical convenience sample of 354 rural (n = 178) and urban (n = 176) Kenyans from the Central Region of Kenya were participants. They responded to a post-traumatic stress screener, attribution style questionnaire and post-traumatic disorder (PTSD) checklist. A regression analysis showed that the urban dweller (UD) sample was significantly more likely to attribute negative events to internal, specific causes than the rural dweller (RD) sample. Findings suggest social support protections in RD to buffer them from negative self-attributions for PTSS among this Kenyan sample.     

大学生的观点采择与助人行为:群体关系与共情反应的不同作用

以56名大学生为被试,采用被试内设计先后在群体内外两种条件下完成观点采择、共情反应与助人行为实验,探讨大学生观点采择在影响其助人行为的过程中,群体关系与共情反应的不同作用。结果表明:(1)在内外群体关系中,大学生观点采择对助人行为的影响均需要借助于共情反应的中介而发挥作用;(2)群体关系在观点采择对助人行为的作用中发挥了一定的调节作用。在内群体关系中,大学生观点采择对助人行为的影响不仅需要借助于共情反应的部分中介效应而发挥作用,同时也存在一定的直接效应;在外群体关系中,大学生观点采择则完全借助于共情反应的中介效应而发挥作用,不存在显著的直接效应。     

Relations of Self-Esteem Concerns,Group Identification,and Self-Stereotyping to In-Group Favoritism

Abstract

In 2 studies, the author examined the effect of collective self-esteem (CSE; J. Crocker & R. Luhtanen, 1993) on people's willingness to display in-group favoritism. To test that self-esteem hypothesis, he measured public CSE, rather than private CSE, because the former parallels a threat to social identity, a state believed to motivate in-group favoritism. Furthermore, the author explored whether group identification and self-stereotyping moderated the effect of public CSE on in-group favoritism. The participants were 92 British and Dutch university employees. As expected, participants high in public CSE displayed more in-group favoritism than did those low in public CSE. Moreover, group identification and self-stereotyping appeared to moderate the effect of CSE.
