Post-error slowing: An orienting account

It is generally assumed that slowing after errors is a cognitive control effect reflecting more careful response strategies after errors. However, clinical data are not compatible with this explanation. We therefore consider two alternative explanations, one referring to the possibility of a persisting underlying problem and one on the basis of the low frequency of errors (orienting account). This latter hypothesis argues that infrequent events orient attention away from the task. Support for the orienting account was obtained in two experiments. Using a new experimental procedure, Experiment 1 demonstrated post-error slowing after infrequent errors and post-correct slowing after infrequent correct trials. In Experiment 2, slowing was observed following infrequent irrelevant tones replacing the feedback signals.     

A comparison of the accuracy and reactivity of methods of monitoring male sexual behavior

Two self-report methods of monitoring male sexuality have been compared—an ongoing method in the form of a diary card and one eliciting retrospective reports in the form of a monthly sexuality interview. Male volunteers were assigned at random to three testing conditions: (a) diary card and monthly interview for 3 months (N=29); (b) three monthly interviews (N=18); and (c) pre- and postinterview only, separated by 2 months (N=21). The correspondence among frequency reports, quality ratings, and number of sexual problems as obtained in diary card and interview measures was examined for respondents in the first condition, revealing that coital frequency and quality ratings were generally quite similar in the two modes of assessment. Interview responses for all subjects were examined for the existence of differential reactive effects according to the frequency of the assessment regimen. No differences emerged among conditions, although a trend for all groups over time was identified. Implications of the results are considered for clinical trials monitoring the effects of new contraceptive methods on sexual functioning.This study was supported by the World Health Organization's Special Programme of Research Development and Research Training in Human Reproduction (Project Nos. 76297 and 79003) and was conducted at King's College Hospital, London.     

积极情绪加速心血管反应恢复的自主神经活动机制

通过对不同情绪唤醒状态下的心率变异性（HRV）和呼吸性窦性心率不齐（RSA）分析,探讨了积极情绪加速高唤醒消极情绪引起的心血管反应向基线恢复的自主神经活动机制。实验表明：与在观看高唤醒恐惧影片结束后观看悲伤影片和中性视频比较,观看高唤醒恐惧影片结束后观看快乐影片加速了高唤醒恐惧影片引起的心率、指脉等心血管反应向基线的恢复;与在观看高唤醒恐惧影片结束后观看悲伤视频和中性视频材料比较,观看高唤醒恐惧影片结束观看快乐影片后的恢复期,被试的迷走神经激活水平迅速增强,迷走神经激活水平甚至超过基线期。因此,积极情绪加速高唤醒消极情绪刺激引起的心血管反应向基线恢复,其自主神经活动机制是在积极情绪状态下个体有更强的迷走神经激活。     

试论《医林改错》中的实物观

清代医家王清任的《医林改错》自1830年刊行之时起即引起广泛关注, 究其原因不仅在于该书改正古人所记脏腑之错误, 关键在于其看待人体的视角及实践方法与传统中医不同——采用了实物观看待人体, 并且实施解剖观察实践, 这种革新举动挑战了传统中医的方法论。与西方近代科学相比较, 发现《医林改错》的思想萌芽和实践方法与之有相似处。结合医学史研习该著作, 看到中医学的方法论与历史环境不可分离, 随时代有所改变。《医林改错》的独特思维能够启发人们对中医方法论的认知。     

Mother–infant interaction and maternal postnatal psychological distress are associated with negative emotional reactivity among infants and toddlers— A FinnBrain Birth Cohort study

Studies have reported mixed findings regarding the effects of mother-infant interaction and maternal distress on children’s negative emotional reactivity. In the current study (N = 134 and 107), we examined the effects of maternal Emotional Availability (sensitivity, structuring, non-intrusiveness and non-hostility) and maternal psychological distress on negative reactivity among children in the FinnBrain birth cohort study. In addition, the possible moderating effect of mother-infant interaction on the associations between maternal psychological distress and children's negative reactivity was examined. We used questionnaires to asses maternal psychological distress, observations of mother-infant interaction and observations as well maternal reports of child temperament to overcome the key limitations of many studies relying on single-method assessments. Our results showed that higher maternal sensitivity and structuring at 8 months of child’s age were associated with lower mother-reported negative reactivity among children at 24 months. Higher maternal postnatal distress associated with higher parent-reported negative reactivity in children at 12 and 24 months of age when the effects of prenatal distress and the quality of mother-infant interaction were controlled for. Mother-infant interaction and maternal psychological distress did not associate with observations of child negative reactivity. We found no moderation effects of mother-infant interaction regarding the associations between maternal distress and children’s negative emotional reactivity. Our findings reflect the importance of developing interventions to reduce the maternal distress symptoms while enhancing maternal sensitivity and structuring to prevent the possible harmful effects of these on child negative reactivity.     

Do maternal power assertive discipline and warmth interact to influence toddlers' emotional reactivity and noncompliance?

Emotional and behavioural self-regulation emerges during infancy and toddlerhood and is heavily influenced by parenting. Parents facilitate toddlers' behavioural regulation (e.g., compliance) by using appropriate control with warmth and managing children's emotional reactivity during situational demands. In contrast, power assertive discipline may strain children's regulatory skills, for example by evoking toddlers' negative affect. However, we have more to learn about how discipline relates to toddlers' self-regulation in the moment and whether concurrent displays of parental warmth may moderate these relations. Mother–toddler dyads (N = 74, M_age = 13.30 months) from low-to-middle income Turkish families participated in a 3-min laboratory task, in which toddlers needed to delay playing with an attractive toy. Maternal discipline, warmth, toddler's emotional reactivity, and noncompliance were coded from observations. Results showed that higher power assertive discipline was associated with more frequent emotional reactivity in toddlers whose mothers' showed warmth during the <84% of the task duration. Maternal warmth was negatively associated with child noncompliance, but warmth did not interact with power assertive discipline in relation to noncompliance. Results suggest that observed power assertive discipline is meaningfully related to toddlers' emotional reactivity and higher levels of expressed maternal warmth attenuates these relations.
