工作记忆内容驱动完全无关刺激捕获注意

研究通过三个实验以检验工作记忆内容能否自动引导注意选择视场中与之匹配的任务完全无关刺激。实验一要求被试在工作记忆保持阶段完成一个视觉搜索任务，结果发现当搜索序列外的无关干扰刺激与工作记忆内容匹配时搜索绩效显著降低；实验二结果表明该干扰效应不能归因于自下而上的启动机制，因为对颜色刺激仅仅进行知觉辨认而没有工作记忆加工时并没有产生启动效应；实验三通过缩短搜索任务刺激的呈现时间以使得被试在完成搜索任务前没有足够时间眼跳至无关干扰刺激，结果发现了与实验一类似的干扰效应，说明在没有眼跳的情况下与工作记忆内容匹配的完全无关刺激可以捕获注意。这些结果表明保持在工作记忆中的信息表征可以自动引导注意选择视场中与之匹配的任务完全无关刺激，为基于工作记忆内容的注意捕获提供了新证据支持。     

Staying and Returning dynamics of young children's attention

In this paper, we decompose selective sustained attending behavior into components of continuous attention maintenance and attentional transitions and study how each of these components develops in young children. Our results in two experiments suggest that changes in children's ability to return attention to a target locus after distraction (“Returning”) play a crucial role in the development of selective sustained attention between the ages of 3.5–6 years, perhaps to a greater extent than changes in the ability to continuously maintain attention on the target (“Staying”). We further distinguish Returning from the behavior of transitioning attention away from task (i.e., becoming distracted) and investigate the relative contributions of bottom-up and top-down factors on these different types of attentional transitions. Overall, these results (a) suggest the importance of understanding the cognitive process of transitioning attention for understanding selective sustained attention and its development, (b) provide an empirical paradigm within which to study this process, and (c) begin to characterize basic features of this process, namely its development and its relative dependence on top-down and bottom-up influences on attention.

Research Highlights

• Young children exhibited an endogenously ability, Returning, to preferentially transition attention to task-relevant information over task-irrelevant information.
• Selective sustained attention and its development were decomposed into Returning and Staying, or task-selective attention maintenance, using novel eye-tracking-based measures.
• Returning improved between the ages of 3.5–6 years, to a greater extent than Staying.
• Improvements in Returning supported improvements in selective sustained attention between these ages.

Near-hand effects are robust: Three OSF pre-registered replications of visual biases in perihand space

ABSTRACT

Although previous work provides evidence that observers experience biases in visual processing when they view stimuli in perihand space, a few recent investigations have questioned the reliability of these near-hand effects. We addressed this controversy by running three pre-registered replication experiments. Experiment 1 was a replication of one of the initial studies on facilitated target detection near the hands in which participants performed an attentional cueing task while placing a single hand either near or far from the display. Experiment 2 tested the same paradigm while adopting the design of a recent experiment that called into question near-hand facilitation. Experiment 3 was a replication of a study in which hand proximity influenced working memory performance in a change detection paradigm. Across all three experiments, we found significant interactions between hand position and stimulus characteristics that indicated the hands’ presence altered visual processing, bolstering evidence favouring the robustness of near-hand effects.     

In the eyes of the beholder: Understanding subtypes of social withdrawal among young Chinese children

In this commentary on Ding et al. (Brit. J. Dev. Psychol., 2015; 33, 159–173), we focus on the following: (1) the authors’ use of vignettes portraying various prototypes of withdrawn children and (2) the cultural interpretation of their findings. We end with some suggestions for future research.     

Children's judgements of social withdrawal behaviours

Ding et al. (Brit. J. Dev. Psychol., 2015; 33, 159–173) demonstrated that Chinese children discriminate between the three subtypes of social withdrawal: Shyness, unsociability, and social avoidance. This commentary on the Ding et al.'s paper highlights the need to further explore the following: (1) children's understanding of the implications of being shy, unsociable, or socially avoidant, including assessing these which we know are associated with outcomes for socially withdrawn children; (2) what additional subtypes might exist naturally within the Chinese culture; and (3) consider the implications of social withdrawal on children's developing social skills.     

Young Chinese children's beliefs about the implications of subtypes of social withdrawal: A first look at social avoidance

The goal of this study was to examine young Chinese children's beliefs about the implications of different subtypes of social withdrawal (e.g., shyness, unsociability), including for the first time, social avoidance. Participants were 133 children in kindergarten (n = 58, M_age = 70.85 months) and grade 1 (n = 75, M_age = 83.49 months). Children were presented with vignettes describing hypothetical peers displaying shy, unsociable, avoidant, and socially competent behaviours and were then asked a series of questions to assess their beliefs about the implications of these different behaviours. Young children made distinctions between social withdrawal subtypes in terms of underlying motivations and emotions. Children also appeared to hold differential beliefs about the implications of different forms of social withdrawal: Of note, they anticipated that socially avoidant peers would experience the most negative outcomes. These findings provide some of the first evidence to suggest that social avoidance represents a distinct form of social withdrawal among young Chinese children. Results are discussed in terms of the importance of distinguishing between different subtypes of social withdrawal in Chinese culture.     

Smoking and social anxiety: the role of false safety behaviors

ABSTRACT

Despite the negative health consequences associated with smoking, most smokers find it difficult to quit. This is especially true for smokers with elevated social anxiety. One factor that may play a role in maintaining smoking with elevated anxiety is false safety behavior (FSB), behaviors geared toward decreasing anxiety short-term but that maintain or increase anxiety long-term. The present study tested whether FSB explained the relation of social anxiety severity with smoking among 71 current smokers. Avoidance-related FSB was the only type of FSB related to cigarettes smoked per day (CPD) and it was robustly related to more CPD. Further, social anxiety was related to CPD indirectly via FSB-Avoidance. Findings suggest that more frequent use of avoidance behaviors to manage anxiety may maintain smoking and may partially explain the high rates of smoking among those with elevated social anxiety. Thus, FSB may be a promising target in smoking cessation interventions, especially among those with elevated social anxiety.
