The Big-Five, sense of control, mental health and fear of crime as contributory factors to attitudes towards punishment

Low sense of control (SoC), mental health problems and fear of crime (FoC) have separately and previously been linked to the Big-Five personality dimensions, but no study to date has sought to integrate these constructs simultaneously in relation to overall punitiveness. These constructs were assessed in 232 participants using an online survey to examine hypothesised relations between FoC and SoC, poorer mental health, Neuroticism (N), Extraversion (E) and Conscientiousness (C), and any resultant punitiveness. Measures were highly correlated, and an exploratory factor analysis summarised these as ‘instability’ and ‘crime attitude’ dimensions. A structural equation model found that high levels of N and poor mental health, as well as low levels of C, E and SoC were related to a latent variable of ‘distress’, which fed into heightened FoC. High levels of C further influenced FoC, which subsequently had an effect on individuals’ greater punitiveness. The current study supports the previous literature regarding variables that influence FoC and attitudes to punishment, and establishes novel associations involving personality.     

Impact of motivation on cognitive control in the context of vigilance lowering: an ERP study

We assessed the effects of time-on-task on cognitive control expressed by the CRN/Nc and the extent to which motivation modulates this relationship. We utilized two groups of participants, who were told that their performance would (evaluation condition) or would not (control condition) be evaluated online. Both groups performed a version of the Eriksen Flanker Task for 60 min. We observed classical vigilance lowering, manifested by a progressive performance decline with time-on-task, in the control, but not in the evaluation, condition. In the latter, performance remained stable throughout the task. ERP analysis indicated the same interaction in our main component of interest, the CRN/Nc, whose amplitude decreased from the first to the last period in the control condition but remained stable over time in the evaluation condition. To our knowledge, this study is the first to demonstrate the impact of motivation on monitoring processes as indexed by the correct response negativity, in the context of a prolonged task. Vigilance lowering caused by a repetitive and prolonged flanker task, results in compromised response control and compromised control of correct responses. Our results suggest that alterations in ACC functioning may underlie vigilance decline and can be viewed as evidence that the action monitoring functions of the ACC can be positively affected by motivation.     

影响控制感剥夺的因素及其后果

控制感是指人们相信自己的选择和行为与相应的结果存在一致性的一种认知状态,对人的身心健康都有重要影响。控制感剥夺之后,人会产生不适症状（如习得性无助和抑郁）。例如,长期剥夺控制感会引起习得性无助,甚至导致抑郁。影响控制感的因素包括社会环境、个性气质、生理基础,甚至可能受到基因的调控作用。深入理解控制感剥夺背后的心理机制能增进对人们自身心理特点的了解,有助于预防或干预一些心理疾病的产生。     

The effect of food toppings on calorie estimation and consumption

In this research we examine the effect of adding a food topping to the base food on consumers' calorie estimation and consumption of the augmented food (base food plus topping). We show that consumers underestimate the calorie content of augmented food with an unhealthy base, especially when the topping is healthy. However, consumers are less likely to underestimate the calorie content of augmented food with a healthy base, regardless of whether the topping is healthy or unhealthy. Further, we show that adding a healthy topping to an unhealthy base makes consumers not only underestimate the calorie content but also eat more of the augmented food.     

Type of physical exercise and inhibitory function in older adults: An event-related potential study

ObjectivesThe present study was to examine the relationship between exercise type and inhibitory function in older adults using neuroelectric indices.DesignA cross-sectional design was employed in the present study.MethodSixty adults (M = 69.42 years) were categorized into open-skill, closed-skill, and irregular exercise groups according to their history of exercise participation. The participants conducted a flanker task while their behavioral performance and event-related brain potentials were assessed.ResultsThe results indicated that regular exercisers, regardless of exercise type, exhibited a faster reaction time across conditions of the flanker task compared to irregular exercisers. For the P300 amplitude of the open-skill exerciser group, the peak amplitude was larger at the vertex site compared to the frontal site, whereas no site differences were observed in the closed-skill and irregular exerciser groups.ConclusionsThese findings extend current knowledge by suggesting that, for older adults, participation in physical exercise involving increased cognitive demand is associated with better neural efficiency in resource allocation for tasks that require interference control.     

不稳定控制感剥夺损害工作记忆刷新功能

控制感剥夺会阻碍工作记忆中的转换功能,但对工作记忆中刷新功能的影响机制尚不清楚。据此,本文通过两个实验来探究控制感剥夺对工作记忆刷新功能的影响。结果发现,相较于基线水平,无论是通过行为无助任务（实验1）还是通过信息无助任务（实验2）操纵的稳定控制感剥夺均未阻碍随后的刷新任务;但在不稳定控制感剥夺的条件下（实验2）,刷新任务的成绩显著降低。这表明,控制感剥夺对工作记忆刷新功能的影响依赖于对其操纵的稳定性。     

Age-related qualitative differences in post-error cognitive control adjustments

Detecting an error signals the need for increased cognitive control and behavioural adjustments. Considerable development in performance monitoring and cognitive control is evidenced by lower error rates and faster response times in multi-trial executive function tasks with age. Besides these quantitative changes, we were interested in whether qualitative changes in balancing accuracy and speed contribute to developmental progression during elementary school years. We conducted two studies investigating the temporal and developmental trajectories of post-error slowing in three prominent cognitive conflict tasks (Stroop, Simon, and flanker). We instructed children (8-, 10-, and 12-year-old) and adults to respond as fast and as accurately as possible and measured their response times on four trials after correct and incorrect responses to a cognitive conflict. Results revealed that all age groups had longer response times on post-error versus post-correct trials, reflecting post-error slowing. Critically, slowing on the first post-error trial declined with age, suggesting an age-related reduction in the orienting response towards errors. This age effect diminished on subsequent trials, suggesting more fine-tuned cognitive control adjustments with age. Overall, the consistent pattern across tasks suggests an age-related change from a relatively strong orienting response to more balanced cognitive control adaptations.     

父母心理控制对流动儿童道德推脱的影响:学校道德氛围感知的中介作用和性别的调节作用

以345名12～17岁初中阶段流动儿童为被试,采用问卷法考察学校道德氛围感知在流动儿童父母心理控制与道德推脱关系中的中介作用,以及性别的调节作用。结果表明:(1)父母心理控制正向预测流动儿童道德推脱;(2)学校道德氛围感知在父母心理控制和流动儿童道德推脱之间起到部分中介作用。(3)性别在父母心理控制与学校道德氛围感知间起调节作用,性别调节了中介模型的前半路径,具体而言,与男孩相较,女孩的学校道德氛围感知受到父母心理控制的影响作用更加显著。
