Avoidance of 20% carbon dioxide-enriched air with humans.

Four college students were exposed to a Sidman avoidance procedure to determine if an avoidance contingency involving 20% carbon dioxide-enriched air (CO2) would produce and maintain responding. In Phase 1, two conditions (contingent and noncontingent) were conducted each day. These conditions were distinguished by the presence or absence of a blue or green box on a computer screen. In the contingent condition, CO2 presentation were delivered every 3 s unless a subject pulled a plunger. Each plunger pull postponed CO2 presentations for 10 s. In the noncontingent condition, CO2 presentations occurred on the average of every 5 min independent of responding. Following stable responding in Phase 1, condition-correlated stimuli were reversed. In both conditions, plunger response rate was high during the contingent condition and low or zero during the noncontingent condition. Furthermore, subjects avoided most CO2 presentations. However, CO2 presentations did not increase verbal reports of fear. Overall, the results from the present study suggest that CO2 can be used effectively in basic studies of aversive control and in laboratory analogues of response patterns commonly referred to as anxiety.     

Power,Conflict, and Community: How Gendered Views of Political Power Influence Women's Political Ambition

We provide a novel approach to understanding the political ambition gap between men and women by examining perceptions of the role of politician. Across three studies, we find that political careers are viewed as fulfilling power‐related goals, such as self‐promotion and competition. We connect these goals to a tolerance for interpersonal conflict and both of these factors to political ambition. Women's lack of interest in conflict and power‐related activities mediates the relationship between gender and political ambition. In an experiment, we show that framing a political career as fulfilling communal goals—and not power‐related goals—reduces the ambition gap.     

Cortisol response and psychological distress predict susceptibility to false memories for a trauma film

For eyewitness testimony to be considered reliable, it is important to ensure memory remains accurate following the event. As many testimonies involve traumatic, as opposed to neutral, events, it is important to consider the role of distress in susceptibility to false memories. The aim of this study was to investigate whether cortisol response following a stressor would be associated with susceptibility to false memories. Psychological distress responses were also investigated, specifically, dissociation, intrusions, and avoidance. Participants were allocated to one of three conditions: those who viewed a neutral film (N?=?35), those who viewed a real trauma film (N?=?35), and a trauma “reappraisal” group where participants were told the film was not real (N?=?35). All received misinformation about the film in the form of a narrative. Participants provided saliva samples (to assess cortisol) and completed distress and memory questionnaires. Cortisol response was a significant predictor of the misinformation effect. Dissociation and avoidance were related to confabulations. In conclusion, following a stressor an individual may differ with regard to their psychological response to the event, and also whether they experience a cortisol increase. This may affect whether they are more distressed later on, and also whether they remember the event accurately.     

The Role of Avoidance in Complicated Grief: A Detailed Examination of the Grief-Related Avoidance Questionnaire (GRAQ) in a Large Sample of Individuals with Complicated Grief

Grief-related avoidance is a significant component of complicated grief, yet has rarely been formally measured in a validated fashion. Further, more work is needed to understand the impact of grief-related avoidance on symptom severity and functional impairment among individuals with complicated grief (CG). The Grief-Related Avoidance Questionnaire (GRAQ; Shear, Monk et al. 2007) was created to assess grief-related avoidance and the present analysis aimed to further develop this measure and construct by confirming the GRAQ’s psychometric properties and examining loss-related predictors of avoidance. In a sample of 393 adults with CG, we found the GRAQ had high internal consistency, with a Cronbach’s alpha of 0.89 and good convergent validity. While the EFA results suggest that the GRAQ may be unidimensional, a 3-factor model generally corresponded with the findings by (Shear, Monk et al. 2007), which suggested the presence of 3 subscales. Loss-related variables age, relationship to the deceased, and cause of death were all significant predictors of GRAQ scores. Our findings support that among individuals with complicated grief, avoidance is common, measurable and an important contributor to impairment.     

Does avoidance‐attachment style attenuate the benefits of being listened to?

We tested both Rogers's hypothesis that listening enables speakers to experience psychological safety and our hypothesis that the benefit of listening for psychological safety is attenuated by avoidance‐attachment style. We tested these hypotheses in six laboratory experiments, a field correlational study, and a scenario experiment. We meta‐analyzed the results of the laboratory experiments and found that listening increased psychological safety on average but that the variance between the experiments was also significant. The between experiment variance in the effect of listening manipulation on psychological safety exposes a methodological challenge in choosing a research paradigm of good‐versus‐normal listening, as opposed to normal‐versus‐poor listening. More importantly, we found, as expected and across all designs, that the higher the avoidance‐attachment style was, the lower the effect of listening on psychological safety. This finding has implications both for practice and for placing a theoretical boundary on Rogers's theory.     

认知抑制与人际宽恕:特质宽恕的调节作用

采用《特质宽恕量表》测量了102名大学生的特质宽恕能力,并通过Flanker任务和情景回忆法评估了被试的认知抑制和人际宽恕水平,目的是探讨特质宽恕、认知抑制与人际宽恕三者之间的关系。结果发现:(1)认知抑制、特质宽恕与人际宽恕各维度之间存在两两显著相关(除认知抑制与仁慈动机之外);(2)特质宽恕对回避、报复和仁慈动机均具有预测作用,而认知抑制则只对报复动机具有预测作用;(3)特质宽恕与认知抑制对回避动机具有负向的调节作用,对仁慈动机具有正向的调节作用。

为探讨自我同情对拖延的影响及其作用机制,采用自我同情量表、大学生拖延量表、大学生羞耻量表和接纳与行动量表对795名大学生进行调查,结果发现：(1)自我同情对大学生拖延行为具有负向预测作用;(2)羞耻在自我同情与大学生拖延行为的负向效应中起到中介作用;(3)经验回避、羞耻在自我同情和大学生拖延行为之间起链式中介作用。     

Intrahippocampal insulin improves memory in a passive-avoidance task in male wistar rats

The main impacts of insulin favor the peripheral organs. Although it functions as a neuropeptide, insulin possesses also some central effects. The aim of this study was to determine the effect of intrahippocampal infusion of insulin on passive avoidance learning in healthy male rats. Thirty male wistar rats were divided into three groups (n=10 each). The experimental group had posttraining insulin infusion into the CA1 region of dorsal hippocampus, after which they were compared with sham (saline) and control (intact) groups. Insulin treated animals had greater latency to enter the dark compartment in compare with saline treated (p=0.023) or control groups (p=0.017). Upon our results, we concluded that intrahippocampal injections of insulin may enhance memory for a simple learning task which supports the concept that insulin possibly plays an endogenous role in memory formation.     

Are members of low status groups perceived as bad, or badly off? Egalitarian negative associations and automatic prejudice

Three studies explored the hypothesis that implicit measures of prejudice can tap negative, yet egalitarian associations. In Study 1, automatically associating African Americans with oppression predicted greater automatic prejudice. In Studies 2 and 3, classically conditioning associations between the novel group Noffians and words like oppressed, maltreated, and victimized led to greater automatic prejudice against Noffians. Results suggest that White Americans’ negative automatic associations with African Americans may partly result from associating members of low status groups with unfair circumstances. Because automatic associations predict prejudiced behaviors, the burden of proof is on those wishing to argue that egalitarian negative associations complicate the assessment of automatic attitudes rather than contribute to prejudiced responses. Discussion focuses on the implications of egalitarian negative associations for the theory and measurement of automatic prejudice.
