System‐perpetuating asymmetries between explicit and implicit intergroup attitudes among indigenous and non‐indigenous Chileans

The present research demonstrates a dissociation between explicit and implicit intergroup evaluation in the reciprocal attitudes between indigenous (Mapuche) and non‐indigenous Chileans. In both social groups, the explicit measures of attitudes towards the respective in‐group and out‐group were compared with the Implicit Association Test scores. The results indicate that the members of the low‐status minority might explicitly express a moderate evaluative preference for their in‐group but might implicitly devalue it. Conversely, the members of the high‐status majority might implicitly devalue their out‐group but might explicitly express no bias. These results are theoretically framed in terms of system justification, conventional stereotypes and motivated correction processes.     

“Math is Hard!” The effect of gender priming on women’s attitudes

In three studies, we examined the effect of a self-relevant category prime on women’s attitudes towards the gender-stereotyped domains of arts (positively stereotyped) and mathematics (negatively stereotyped). In Study 1, women who were subtly reminded of the category female (Study 1a) or their gender identity (Study 1b) expressed more stereotype consistent attitudes towards the academic domains of mathematics and the arts than participants in control conditions. In Study 2, women who were reminded of their female identity similarly demonstrated a stereotype-consistent shift in their implicit attitudes towards these domains relative to women in a control condition. The potential role of the working self-concept in mediating social category priming effects as well as the practical implications of these findings are discussed.     

言语产生老化中的抑制损伤:来自不同任务的证据

通过3个实验,探讨干扰抑制在言语产生老化中的作用。实验1采用经典Stroop任务,发现老年人在高水平的、自动的语义激活时产生了更大的抑制困难。实验2操纵潜在竞争词的语义激活水平,发现在潜在竞争词处于低水平的语义激活时,老年人的抑制能力与年轻人相当;在潜在竞争词处于高水平的语义激活时,老年人表现出抑制能力的劣势。实验3采用造句任务,发现老年人在抑制角色冲突时存在着较大的困难,老年人在顺序不一致的条件下的造句成绩显著差于年轻人。整个研究表明,老年人在言语产生中的抑制能力差于年轻人,但抑制老化效应受潜在干扰刺激的激活水平影响。     

Anxiety between personality and cognition: The gray zone

The aim of the study was to explore relations between Gray’s revised Reinforcement Sensitivity Theory (rRST) systems (Behavior Inhibition, Behavior Activation and Fight/Flight/Freeze System – BIS, BAS and FFFS) and two cognitive vulnerabilities to anxiety disorders (Intolerance of Uncertainty – IU and Anxiety Sensitivity – AS). The sample comprised 223 participants. The results suggested that BIS was a significant predictor of all components of the anxiety vulnerability measures. However, Freeze and Flight had also significant contributions, particularly in explaining vulnerabilities to physical and social threats as well as inhibitory behaviours while facing uncertainty. The findings provide insights into the nature of AS and IU which is in accordance with the rRST.     

Priming involuntary autobiographical memories in the lab

Involuntary autobiographical memories (IAMs) are recollections of personal past that frequently and spontaneously occur in daily life. Initial studies by Mace (2005) showed that deliberately reminiscing about a certain lifetime period (e.g., high school) significantly increased the number of different IAMs from the same period in subsequent days, suggesting that priming may play a significant role in the retrieval of IAMs in everyday life. In the present study, we used a modified experimental paradigm, originally used by Schlagman and Kvavilashvili (2008), to study IAMs under well-controlled laboratory conditions. Participants completed a monotonous vigilance task twice and reported the occurrence of any spontaneous thoughts that were later classed as IAMs or other thoughts. Priming was manipulated by having experimental participants reminiscing about high school period between the two vigilance tasks and control participants playing simple games. Results showed that participants in the experimental group reported IAMs relating to high school period more frequently during the second vigilance task than those in the control group. In the experimental group, the number of high school memories was marginally higher in the second vigilance task compared to the first vigilance task with the medium effect size, but this within subjects effect was not significant in the control group. Finally, priming also enhanced the retrieval of more remote IAMs in the experimental group compared to the control group. These results suggest that priming may play a significant role in the activation and recall of IAMs and open up interesting avenues for future research.     

Simple Co‐Occurrence Statistics Reproducibly Predict Association Ratings

What determines human ratings of association? We planned this paper as a test for association strength (AS) that is derived from the log likelihood that two words co‐occur significantly more often together in sentences than is expected from their single word frequencies. We also investigated the moderately correlated interactions of word frequency, emotional valence, arousal, and imageability of both words (r's ≤ .3). In three studies, linear mixed effects models revealed that AS and valence reproducibly account for variance in the human ratings. To understand further correlated predictors, we conducted a hierarchical cluster analysis and examined the predictors of four clusters in competitive analyses: Only AS and word2vec skip‐gram cosine distances reproducibly accounted for variance in all three studies. The other predictors of the first cluster (number of common associates, (positive) point‐wise mutual information, and word2vec CBOW cosine) did not reproducibly explain further variance. The same was true for the second cluster (word frequency and arousal); the third cluster (emotional valence and imageability); and the fourth cluster (consisting of joint frequency only). Finally, we discuss emotional valence as an important dimension of semantic space. Our results suggest that a simple definition of syntagmatic word contiguity (AS) and a paradigmatic measure of semantic similarity (skip‐gram cosine) provide the most general performance‐independent explanation of association ratings.     

“Do More,Feel Better”: Pilot RCT of Lay-Delivered Behavioral Activation for Depressed Senior Center Clients

This pilot randomized control trial (RCT) tested “Do More, Feel Better” (DMFB), a lay-delivered Behavioral Activation intervention for depressed senior center clients. The study examined: (1) the feasibility of training older lay volunteers to fidelity; and (2) the acceptability, safety, and impact of the intervention. Twenty-one lay volunteers at four senior centers were trained in DMFB. Fifty-six depressed clients were randomized to receive 9 sessions of DMFB or Behavioral Activation delivered by social workers (MSW BA). Research assessments of overall client activity level (BADS) and depression severity (HAM-D) were conducted at baseline and Weeks 3, 6, and 9. Eighty-one percent of lay volunteers who underwent training were formally certified in DMFB. Depressed clients receiving each intervention reported high levels of satisfaction and showed large and clinically significant changes in 9-week activity level (d ≥ 1.35) and depression severity (d ≥ 3.34). Differences between treatment groups were very small for both activity level (d_MSW = 0.16; 95% CI, -0.70 to 1.02) and depression (d_MSW = 0.14; 95% CI, -0.63 to 0.91). Increases in activity level were associated with decreases in depression (β = -0.42; 95% CI, -0.55 to -0.30). Both interventions appeared to work as intended by increasing activity level and reducing depression severity. “Do More, Feel Better” shows the potential of evidence-based behavioral interventions delivered by supervised lay volunteers, and can help address the insufficient workforce available to meet the mental health needs of community-dwelling older adults.     

Telephone-Based Behavioral Activation for Improving Sleep Quality in Family Caregivers of People With Dementia: A Pilot Randomized Controlled Trial

Sleep disturbances are common among family caregivers of people with dementia (PWD). Although behavioral activation (BA) shows the potential to improve sleep quality, to date, evidence for this treatment’s feasibility and efficacy for family caregivers of PWD is limited. Therefore, this study pilot tested an evidence-based BA protocol for improving sleep quality in Chinese family caregivers of PWD. The BA intervention involved eight weekly individual telephone-based sessions designed to teach caregivers specific BA techniques. Sleep quality and depression were measured using the Chinese versions of the Pittsburgh Sleep Quality Index (PSQI) and Center for Epidemiologic Studies Depression (CES-D) Scale, respectively. This study also measured leisure activity, positive aspect of caregiving, caregiving burden, health status, and relationship satisfaction. All participants were asked to complete the assessments on paper at baseline and immediately after the intervention. After completing the pilot randomized controlled trial, semistructured interviews were conducted to explore participants’ experiences participating in the BA intervention. A total of 71 family caregivers of PWD (35 in the intervention group and 36 in the control group) were recruited. The majority of participants were female (n = 53, 74.65%), and their mean age was 54.07 years (SD = 10.95). Compared with controls, caregivers in the intervention group displayed significantly greater improvement in sleep quality, as well as perceptions of positive aspects of caregiving and reduction of depression. Most participants were very satisfied with the intervention. These findings suggest that individual telephone-based BA interventions are feasible, acceptable, and effective in improving sleep quality and psychological health in family caregivers of PWD. These results contribute to the literature by providing evidence for developing effective, accessible, and sustainable BA interventions for family caregivers of PWD.     

Development and Preliminary Feasibility Study of a Brief Behavioral Activation Mobile Application (Behavioral Apptivation) to Be Used in Conjunction With Ongoing Therapy

Depressive symptoms are the most frequently treated psychiatric condition in the United States. Brief behavioral activation treatment for depression (BATD) is a popular, evidence-based psychotherapy with strong research support for the treatment of depression. In this paper, we describe the development and initial pilot feasibility testing of a BATD mobile application (Behavioral Apptivation) to be used by patients and therapists in conjunction with BATD therapy. We present information regarding the app development process as well as results from a small open-label feasibility trial of the app utilized in conjunction with individual BATD. We include a case series from the open-label trial highlighting how Behavioral Apptivation can be utilized in clinical practice.     

知识经验与顿悟：来自认知神经科学的证据

知识经验对于顿悟问题解决是一把双刃剑,强势知识会阻碍顿悟问题解决,弱势知识才是顿悟问题解决的关键。强势知识引导的组块效应、约束效应和固着效应等心理定势现象,“帮助”问题解决者以惯用方案来理解、思考和解决问题。之所以会这样,可能是因为大脑内存在一套具有优先级差的层级加工系统,赋予惯用方案的优先级最高。不过,惯用方案不仅不能够解决顿悟问题,而且还会通过注意竞争和注意失灵方式来阻碍新异方案的探索和执行,所以,问题解决者往往都会进入思维僵局。僵局的打破和顿悟的实现,需要抑制住强势知识及其相关的惯用方案、激活弱势知识和新异方案,这违反了大脑的认知加工惯性,是很难以自发发生的。但是,可以通过激活扩散来增强弱势知识的激活水平,或者是拓宽注意范围、提高注意灵活性来增加弱势知识激活的可能性,从而促进顿悟问题解决。
