The role of attitudes towards the targets of behaviour in predicting and informing prenatal testing choices

Research considering the role of attitudes in prenatal testing choices has commonly focused on the relationship between the attitude towards undergoing testing and actual testing behaviour. In contrast, this study focused on the relationship between testing behaviour and attitudes towards the targets of the behaviour (in this case people with Down syndrome (DS) and having a baby with DS). A cross-sectional, prospective survey of 197 pregnant women measured attitudes towards the targets of prenatal testing along with intentions to use screening and diagnostic testing, and the termination of an affected pregnancy. Screening uptake was established via patient records. Although attitudes towards DS and having a baby with DS were significantly associated with screening uptake and testing and termination intentions, unfavourable attitudes were better than favourable ones at predicting these outcomes. For example, in the quartile of women with the ‘most favourable’ attitude towards people with DS 67% used screening although only 8% said they would terminate an affected pregnancy. Qualitative data suggested that not all women considered personal attitudes towards DS to be relevant to their screening decisions. This finding has implications for the way in which informed choice is currently understood and measured in the prenatal testing context.     

Forgiveness is an emotion-focused coping strategy that can reduce health risks and promote health resilience: theory,review, and hypotheses

Experimental evidence suggests that when people are transgressed against interpersonally, they often react by experiencing unforgiveness. Unforgiveness is conceptualized as a stress reaction. Forgiveness is one (of many) ways people reduce unforgiveness. Forgiveness is conceptualized as an emotional juxtaposition of positive emotions (i.e., empathy, sympathy, compassion, or love) against the negative emotions of unforgiveness. Forgiveness can thus be used as an emotion-focused coping strategy to reduce a stressful reaction to a transgression. Direct empirical research suggests that forgiveness is related to health outcomes and to mediating physiological processes in such a way as to support the conceptualization that forgiveness is an emotion-focused coping strategy. Indirect mechanisms might also affect the forgiveness-health relationship. Namely, forgiveness might affect health by working through social support, relationship quality, and religion.

协作抑制的认知机制

协作抑制是指当人们在一个记忆小组中一起提取信息的时候,小组提取的信息总量比等量个体提取的信息总量要少.心理学研究者致力于从认知角度对该现象进行解释,主要的理论解释有提取策略破坏假说和提取抑制假说.前者认为小组成员的提取结果对组内其他成员的信息组织策略产生了干扰,导致小组的提取成绩低.而后者认为小组内成员的提取结果会抑制其他成员对非提取项目的表征,降低小组协作提取能力,出现协作抑制.本文对两种理论假说的提出背景,基本观点,证据支持及现有争论进行了介绍,同时指出了未来的研究应关注于对两种机制的关键矛盾点进行区别性检验、对不同认知机制在不同条件下成立可靠性的检验以及通过对编码阶段进行操控来进一步考察协作抑制的认知机制.     

Failure to exploit learned spatial value information during visual search

ABSTRACT

In recent years there has been rapid proliferation of studies demonstrating how reward learning guides visual search. However, most of these studies have focused on feature-based reward, and there has been scant evidence supporting the learning of space-based reward. We raise the possibility that the visual search apparatus is impenetrable to spatial value contingencies, even when such contingencies are learned and represented online in a separate knowledge domain. In three experiments, we interleaved a visual choice task with a visual search task in which one display quadrant produced greater monetary rewards than the remaining quadrants. We found that participants consistently exploited this spatial value contingency during the choice task but not during the search task – even when these tasks were interleaved within the same trials and when rewards were contingent on response speed. These results suggest that the expression of spatial value information is task specific and that the visual search apparatus could be impenetrable to spatial reward information. Such findings are consistent with an evolutionary framework in which the search apparatus has little to gain from spatial value information in most real world situations.     

Adult age differences in subjective and objective measures of strategy use on a sequentially cued prediction task

Differences in strategy use are thought to underlie age-related performance deficits on many learning and decision-making tasks. Recently, age-related differences in learning to make predictions were reported on the Triplets Prediction Task (TPT). Notably, deficits appeared early in training and continued with experience. To assess if age differences were due to early strategy use, neural networks were used to objectively assess the strategies implemented by participants during Session 1. Then, the relationship between these strategies and performance was examined. Results revealed that older adults were more likely to implement a disadvantageous strategy early in learning, and this led to poorer task performance. Importantly, the relationship between age and task performance was partially mediated by early strategy use, suggesting that early strategy selection played a role in the lower quality of predictions in older adults.     

Ageing and attentional control

The research examines the structural bottleneck account and the resource account of the substantial dual-task deficits among older adults. Procedures from two common dual-task methodologies—the psychological refractory period and the relative-priority manipulation—were used to encourage maximization of the joint performance. Performance and time-sharing strategies from subjects between the ages of 20 and 70 years were examined. Age-related declines in time-sharing efficiency and in the precision of the executive control process were observed. The age-related effect was larger when two manual responses were required than when one manual and one vocal response were required, but no evidence for obligatory sequential processing was found. Except for the most demanding conditions, comparable practice effects were observed between the younger and older subjects, suggesting considerable cognitive plasticity in the older subjects. Implications for the two attentional accounts were discussed.     

进化心理学视角下母亲教养行为的代际传承性研究

采用问卷法,从生命史理论的角度探讨母亲教养行为的代价传递性。研究问题一显示,童年期家庭环境的艰苦性和不可预测性不能预测个体成年后的生命史策略,原生家庭母亲的专制型教养方式通过焦虑型依恋行为的中介作用可以间接地负向预测成年女儿的生命史慢策略,原生家庭母亲的民主型教养方式可以直接预测成年女儿的生命史慢策略;研究问题二显示,生命史慢策略在原生家庭母亲的民主型教养行为和成年女儿的合作型协同教养行为之间起着完全中介作用。
