直升机教养的内涵、影响和后效

直升机教养是父母对始成年期青少年普遍采用的一种教养方式,它是指父母给孩子过度的支持,较多地控制其行为,并不能给予孩子适合其年龄的自主权的教养方式。本文从直升机教养的概念辨析、影响因素和作用后效方面进行了系统梳理和整合分析,未来研究需要扩展研究对象和内容、精细探讨直升机教养的作用机制、重视我国始成年人的直升机教养,深入考察直升机教养与健康成长的因果关系。     

消极元刻板印象激活对老年人认知表现的影响

本研究以59名老年人为研究对象,采用N-back认知任务探讨在不同难度的认知负荷任务中老年人消极元刻板印象激活的认知效应。结果发现：1、消极元刻板印象激活组的正确率显著低于未激活组;高认知负荷任务组的正确率显著低于低认知负荷任务组。2、消极元刻板印象激活组的反应时显著长于未激活组;高认知负荷任务组的反应时显著长于低认知负荷任务组;组别与任务难度之间交互作用达到边缘显著,在低认知负荷任务中,消极元刻板印象激活组和未激活组的反应时差异不显著,在高认知负荷任务中,消极元刻板印象激活组的反应时显著长于未激活组。上述结果表明,老年人消极元刻板印象的激活导致了负面的认知效应。     

编码意识对注意促进效应的影响——基于R/K范式的研究

注意促进效应指学习阶段采用目标探测性质的二级任务,不仅不会降低同时呈现的背景信息的编码加工,反而会促进其记忆。为进一步探究对背景信息的编码意识是否会影响该效应,本研究设置了有意与无意两种编码条件,并引入“记得/知道”判断进一步将再认区分为回想和熟悉性。结果表明,无意编码下也会产生ABE,但不同的编码条件下,目标探测所促进的背景信息的编码加工存在差异。有意编码条件下,目标探测促进的更多是对背景信息的精细加工,而无意编码条件下,目标探测促进的更多是对背景信息的知觉加工。     

基于双眼视差探讨深度知觉信息对背景线索效应的影响

背景线索效应是由重复场景导致搜索效率提高的现象。以往研究发现三维场景下能获得背景线索效应,但对三维场景下深度知觉线索信息如何影响空间场景提供有效线索引导注意仍缺乏实证研究。本研究以矩阵刺激为材料,通过设置不同的刺激项目水平数探讨深度知觉线索对背景线索效应的影响模式。结果发现:(1)在场景布局由较少项目构成时,深度知觉线索提供目标与刺激项目的有效联结,获得背景线索效应;(2)当刺激项目水平达到一定程度时,深度知觉线索增加了背景线索任务的搜索难度,干扰了重复场景中的背景信息对注意的指导性加工,背景线索效应消失。研究结果为三维场景下深度信息对空间场景中注意引导加工的影响提供了证据。     

Halo effects from agency behaviors and communion behaviors depend on social context: Why technicians benefit more from showing tidiness than nurses do

We investigate halo effects from agency behaviors and communion behaviors in different social contexts. According to the salient dimension model, attributes elicit halo effects on the ratings of other, unrelated attributes when they are relevant in a situation. Given that communion behaviors are more relevant in social and care‐related jobs, they should elicit stronger halo effects than agency behaviors in this context. In the context of scientific and technical jobs, this difference should be weakened or even reversed. Three experiments support the predicted interaction of context and behavior on halo effects. This interaction was stronger for negative than for positive behaviors. These results have implications for understanding the basic processes of halo effects as well as their real‐world effects in job‐related contexts.     

Supporting Mentoring Relationships of Youth in Foster Care: Do Program Practices Predict Match Length?

Implementation of research‐ and safety‐based program practices enhance the longevity of mentoring relationships, in general; however, little is known about how mentoring programs might support the relationships of mentees in foster care. Benchmark program practices and Standards in the Elements of Effective Practice for Mentoring, 3rd Edition (MENTOR, 2009) were assessed in the current study as predictors of match longevity. Secondary data analyses were conducted on a national agency information management database from 216 Big Brothers Big Sisters agencies serving 641 youth in foster care and 70,067 youth not in care from across the United States (Mean = 11.59 years old at the beginning of their matches) in one‐to‐one, community‐based (55.06%) and school‐ or site‐based (44.94%) matches. Mentees in foster care had shorter matches and matches that were more likely to close prematurely than mentees who were not in foster care. Agency leaders from 32 programs completed a web‐based survey describing their policies and practices. The sum total numbers of Benchmark program practices and Standards were associated with match length for 208 mentees in foster care; however, neither predicted premature match closure. Results are discussed in terms of how mentoring programs and their staff can support the mentoring relationships of high‐risk youth in foster care.     

The effect of layout and pacing on learning from diagrams with unnecessary text

Although the presentation of extraneous (i.e., irrelevant or unnecessary) information hinders learning, it is unclear whether and how layout and pacing influence this effect. In two experiments, participants learned how the heart functions using four different layouts: a diagram presented without unnecessary text (diagram only), with unnecessary text separated from the diagram (separated) or integrated into the diagram (integrated), or with separated unnecessary text and the instruction to integrate (integration instruction). In Experiment 1, study time was self‐paced for half of the participants and system paced for the other half. There were no effects of layout and of pacing on learning, although system pacing was more effortful than self‐pacing. In Experiment 2, which was system paced and employed eye tracking, the integrated condition showed worse learning outcomes than the separated condition. Moreover, in the integrated condition, participants made more integration attempts between the unnecessary text and the diagram than in the separated condition.     

Test-potentiated learning: three independent replications,a disconfirmed hypothesis,and an unexpected boundary condition

Arnold and McDermott [(2013). Test-potentiated learning: Distinguishing between direct and indirect effects of testing. Journal of Experimental Psychology: Learning, Memory, and Cognition, 39, 940–945] isolated the indirect effects of testing and concluded that encoding is enhanced to a greater extent following more versus fewer practice tests, referred to as test-potentiated learning. The current research provided further evidence for test-potentiated learning and evaluated the covert retrieval hypothesis as an alternative explanation for the observed effect. Learners initially studied foreign language word pairs and then completed either one or five practice tests before restudy occurred. Results of greatest interest concern performance on test trials following restudy for items that were not correctly recalled on the test trials that preceded restudy. Results replicate Arnold and McDermott (2013) by demonstrating that more versus fewer tests potentiate learning when trial time is limited. Results also provide strong evidence against the covert retrieval hypothesis concerning why the effect occurs (i.e., it does not reflect differential covert retrieval during pre-restudy trials). In addition, outcomes indicate that the magnitude of the test-potentiated learning effect decreases as trial length increases, revealing an unexpected boundary condition to test-potentiated learning.     

Working memory capacity and the spacing effect in cued recall

Spacing repetitions typically improves memory (the spacing effect). In three cued recall experiments, we explored the relationship between working memory capacity and the spacing effect. People with higher working memory capacity are more accurate on memory tasks that require retrieval relative to people with lower working memory capacity. The experiments used different retention intervals and lags between repetitions, but were otherwise similar. Working memory capacity and spacing of repetitions both improved memory in most of conditions, but they did not interact, suggesting additive effects. The results are consistent with the ACT-R model’s predictions, and with a study-phase recognition process underpinning the spacing effect in cued recall.
