Older (but not younger) preschoolers understand that knowledge differs between people and across time

We examined 3‐ to 5‐year‐olds' understanding of general knowledge (e.g., knowing that clocks tell time) by investigating whether (1) they recognize that their own general knowledge has changed over time (i.e., they knew less as babies than they know now), and (2) such intraindividual knowledge differences are easier/harder to understand than interindividual differences (i.e., Do preschoolers understand that a baby knows less than they do?). Forty‐eight 3‐ to 5‐year‐olds answered questions about their current general knowledge (‘self‐now’), the general knowledge of a 6‐month‐old (‘baby‐now’), and their own general knowledge at 6 months (‘self‐past’). All age groups were significantly above chance on the self‐now questions, but only 5‐year‐olds were significantly above chance on the self‐past and baby‐now questions. Moreover, children's performance on the baby‐now and self‐past questions did not differ. Our findings suggest that younger preschoolers do not fully appreciate that their past knowledge differs from their current knowledge, and that others may have less knowledge than they do. We situate these findings within the research on knowledge understanding, more specifically, and cognitive development, more broadly.     

Examining profiles of the big five and sensation seeking among competitive climbers

The present study sought to identify distinct personality profiles in competitive climbers (N = 331, Mean age = 29.85, SD = 10.92), and also sought to explore whether these climbers differed in their sensation seeking tendencies based on these personality profiles. Employing a cross-sectional design, participants completed measures of the big five personality dimensions (agreeableness; conscientiousness; extraversion; neuroticism; openness to experience) and sensation seeking (boredom susceptibility; experience seeking; disinhibition; thrill and adventure seeking). Latent profile analysis identified four distinct big five personality profiles (Curious and Impulsive; Emotionally Unstable; Healthy; and Measured and Compliant). MANCOVA and follow-up ANCOVAs demonstrated significant differences between the four personality profiles in relation to thrill and adventure seeking, experience seeking, and disinhibition. The findings suggest that the identification of distinct personality profiles using a person-centred approach is a useful way of distinguishing and optimizing typical behaviors and preferences in adventure sports in the future.     

Taking a naïve other's perspective to debias the hindsight bias: Did it backfire?

Hindsight bias is a phenomenon that occurs when outcome knowledge interferes with the ability to accurately recall judgments made in a previous, naïve state. Also known as the “knew it all along” bias, we aimed to diminish the bias by having individuals take the perspective of a naïve other, as a way of encouraging acceptance that they had, in fact, not known it all along. Adult participants were given blurry-to-clear images incrementally until they were able to identify the object and were then re-presented with the same sequence of images and asked to make a judgment about when they had identified the item correctly the first time. They were also asked to judge when they thought a naïve peer (Experiments 1 and 2), or a naïve child (Experiment 2) could identify the objects. Results showed a robust hindsight bias in all perspectives, and sporadic success at eliminating the bias. When taking the perspective of a naïve peer, there were failures and successes; when taking the perspective of a naïve child, there was an ultra-debiasing, or a reverse hindsight bias. However, did the manipulation backfire? We conclude that while the manipulation of thinking like a naïve child may have eliminated the bias, participants seemed to use an “adults know best” rule rather than accepting past naivete for themselves.     

建议距离和线索丰富性对建议采纳的影响

基于社会判断理论,研究以80名大学生为被试,通过JAS范式考察了建议距离对建议采纳和自信心变化的影响以及线索丰富性在这一过程中的作用。结果发现随着建议距离的增加,建议权重仅在线索信息较丰富的情况下呈先增后减的倒U型趋势,而绝对观点转变和自信心变化均不受线索丰富性的影响,分别呈递增和递减趋势。即建议距离对不同建议采纳指标有不同影响,建议距离与建议权重之间存在倒U曲线关系且线索丰富性起到了调节作用。     

Empowering public service workers to face bystander conflict: Enhancing resources through a training intervention

Public service employees work in occupations that are accompanied with high psychosocial risks. Police, firefighters, and paramedics are increasingly being confronted with argumentative, conflicting bystanders that frustrate them in executing their task. We developed a resource‐enhancement intervention and tested its usefulness for securing employees’ effective functioning and well‐being in bystander conflict. In a simulation‐based pre‐test post‐test control group design, paramedics in the intervention condition received training about how to increase their resources in terms of conflict management efficacy, perspective taking, task support, and emotional support. For those in the control condition, no such training was provided. Comparing pre‐ and post‐test measures (n = 81) of the participants in the intervention and control groups, we found evidence that the intervention successfully increased employees’ resources over time. Moreover, we found considerable support for a positive link between these resources and employees’ affective well‐being and job dedication. Thus, our study suggests that a resource‐enhancing intervention can serve as an important means to protect public service employees against the deleterious effects of bystander conflict.

Practitioner points

• A resource‐enhancing intervention can protect public service employees against the deleterious effects of bystander conflict.
• Resources related to dealing with a hindering bystander, as well as resources facilitating the continuation of the primary task, are positively associated with employees’ affective well‐being, job dedication, and job performance.

     

The Power of a “Maverick” in Collaborative Problem Solving: An Experimental Investigation of Individual Perspective‐Taking Within a Group

Integrating different perspectives is a sophisticated strategy for developing constructive interactions in collaborative problem solving. However, cognitive aspects such as individuals’ knowledge and bias often obscure group consensus and produce conflict. This study investigated collaborative problem solving, focusing on a group member interacting with another member having a different perspective (a “maverick”). It was predicted that mavericks might mitigate disadvantages and facilitate perspective taking during problem solving. Thus, 344 university students participated in two laboratory‐based experiments by engaging in a simple rule‐discovery task that raised conflicts among perspectives. They interacted with virtual partners whose conversations were controlled by multiple conversational agents. Results show that when participants interacted with a maverick during the task, they were able to take others’ perspectives and integrate different perspectives to solve the problem. Moreover, when participants interacted in groups with a positive mood, groups with a maverick outperformed groups having several perspectives.     

Emotion regulation and risk taking: Predicting risky choice in deliberative decision making

Only very recently has research demonstrated that experimentally induced emotion regulation strategies (cognitive reappraisal and expressive suppression) affect risky choice (e.g., Heilman et al., 2010). However, it is unknown whether this effect also operates via habitual use of emotion regulation strategies in risky choice involving deliberative decision making. We investigated the role of habitual use of emotion regulation strategies in risky choice using the “cold” deliberative version of the Columbia Card Task (CCT; Figner et al., 2009). Fifty-three participants completed the Emotion Regulation Questionnaire (ERQ; Gross & John, 2003) and—one month later—the CCT and the PANAS. Greater habitual cognitive reappraisal use was related to increased risk taking, accompanied by decreased sensitivity to changes in probability and loss amount. Greater habitual expressive suppression use was related to decreased risk taking. The results show that habitual use of reappraisal and suppression strategies predict risk taking when decisions involve predominantly cognitive-deliberative processes.     

Possible Insomnia Predicts Some Risky Behaviors Among Adolescents When Controlling for Depressive Symptoms

Attachment theory asserts that secure attachment representations are developed through sensitive and consistent caregiving. If sensitive caregiving is a constant characteristic of the parent, then siblings should have concordant attachment classifications. The authors explored maternal attachment quality assessed by the Attachment Q-Set, maternal sensitivity, and specific mother–child interactions between siblings. Hour-long observations took place in the homes of 9 preschool sibling pairs and their immediate caregivers. The interactions were analyzed using a modified version of Bales’ Small Group Analysis. The results reveal attachment discordance in a third of sibling pairs. While maternal sensitivity was higher with older siblings and mothers displayed more positive emotions when interacting with their younger siblings, attachment quality was not associated with birth order. Therefore, a shift toward a more contextual, family-based perspective of attachment is recommended to further understand how attachment strategies are created and maintained within the child's everyday context.     

Life Events and Prosocial Behaviors Among Young Adults: Considering the Roles of Perspective Taking and Empathic Concern

The authors examined the altruism born of suffering model in a culturally diverse sample of young adults. They hypothesized that major life events would interact with perspective taking to predict empathic concern, which would predict multiple types of prosocial behaviors among young adults. The sample included 202 young adults (M age = 20.94?years; 76.5% girls; 36.5% White, 50.5% Latino) who reported on their exposure to major life events, perspective taking and empathic responding, and tendency to engage in six forms of prosocial behaviors. Life events indirectly, positively predicted prosocial behaviors via empathic concern. Empathic concern and perspective taking also interacted to predict empathic responding. The results demonstrated links that support the altruism born of suffering model, suggesting that life stressors might not always be negative and might promote resilience and social connection among young adults under specific conditions.
