年老过程认知作业完成量与作业速度相互关系的研究

本工作应用自行设计的计算机逐级限速程序,研究了年老过程四项认知作业完成量与作业速度的相互关系。被试350人,46—75岁。研究结果表明:1、随着计算机所限时间的缩短,各项作业完成量均随年老下降迅速,作业完成量对于作业速度的依存关系随年老表现极为明显;2、在逐级限速条件下,四项认知作业完成量的年老敏感性顺序与作业速度的年老敏感性顺序基本相同,即是:符号数字、心算、计数和数字鉴别。     

Performance of children under a multiple random-ratio random-interval schedule of reinforcement

Three children, aged 1.5, 2.5, and 4.5 years, pressed telegraph keys under a two-component multiple random-ratio random-interval schedule of reinforcement. In the first condition, responses on the left key were reinforced under a random-interval schedule and responses on the right key were reinforced under a random-ratio schedule. In the second condition, the schedule components were reversed. In the third condition, the original arrangement was reinstated. For all subjects, rates of responding were higher in the random-ratio component despite higher rates of reinforcement in the random-interval component. The average interreinforcement interval of the random-interval component was increased in the fourth condition, resulting in more similar rates of reinforcement for both schedule components, and then returned to its original value in the fifth condition. In both conditions, all subjects continued to exhibit higher rates of responding in the ratio component than in the interval component. Although these observations are consistent with results from studies with pigeons, it is argued that the response-rate differences between the interval and ratio schedule components are sufficient to demonstrate schedule sensitivity.     

Humans' sensitivity to variation in reinforcer amount: Effects of the method of reinforcer delivery

Two experiments examined human subjects' sensitivity to variation in reinforcer amount under different methods of reinforcer delivery. Subjects chose between schedules varying in terms of amount and/or delay of reinforcement, the reinforcer being points exchangeable for money. In Experiment 1, reinforcer amount was manipulated by varying the monetary value of the points across conditions while the number of seconds of access to a consummatory response remained constant. Choice was strongly sensitive to reinforcer amount and indicative of self-control, as in previous experiments. In Experiment 2, reinforcer amount was manipulated by automatically delivering different numbers of points during the amount period, and the consummatory response was eliminated. Sensitivity to variation in reinforcer amount was significantly lower than in Experiment 1. Furthermore, the subjects in Experiment 2 exhibited significantly less self-control than did the subjects in Experiment 1. Humans' sensitivity to variation in reinforcer amount appears to be affected by factors that enhance the discrimi-nability of the consequences of responding.     

The impact of the “Attachment and Biobehavioural Catch-Up” program on attachment related parent behavior—A systematic review

“Attachment and Biobehavioural Catch-Up” (ABC) is a 10 session home visiting program, grounded in attachment theory. It aims to improve child emotion regulation, attachment and behavioral outcomes through changing caregivers’ attachment related behaviors. There is increasing evidence with respect to the effectiveness of ABC in producing positive child outcomes, but the intervention's direct effect on parent outcomes remains unclear. This review examined the association of ABC with attachment related parent outcomes. The PubMed, EMBASE, PyschINFO and SCOPUS databases were searched for relevant studies in August 2021, and again in April 2022. The eligibility criteria for included studies were (1) infants aged 0–27 months at time of the ABC intervention, (2) “at risk” parents, (3) controlled trials published in peer-reviewed journals and (4) utilized a measure of attachment related parent outcomes. Eleven eligible studies were included. The findings showed ABC had a significant small to medium effect on a variety of attachment related parent outcomes among parents presenting with multiple psychosocial risk factors. “Sensitivity” was measured most frequently, with small to medium main effect sizes recorded at follow-up, compared to controls. Implications for the clinical effectiveness of the ABC program in community settings are discussed. Future research should clarify who ABC is most effective for and how it compares to similar interventions.     

Changes in patterns of Early Mother-Child Interaction: A longitudinal study of the first 18 months of life

ObjectiveThe main objective of the present longitudinal study is to describe the progression of early adult-child interactions between the first and second years of life. Changes identified in interactions are described, focusing on both the qualitative aspects of maternal responses, as well as maternal response latency to the child's behavior using a microanalytical methodology that collected data on maternal and child behavior in real-time without losing sight of the temporal dimension.ParticipantsThis study examined 52 mother-child dyads from intact families that presented no psychological, social, or biological risk factors at 6, 12 and 18 months of age.InstrumentCITMI-R (early mother-child interaction coding system, revised edition) was used to assess early mother-infant interactions during free play sessions between mother and child the.ResultsThe results indicate that some components of maternal sensitivity improve as children progress towards the second year of life, detecting an increase in sensitive maternal behavior and a decrease in intrusive behavior in the evolutive observed period; moreover, regarding latency of maternal response, we observed that mothers of older children give more time for their children to explore, which stimulates autonomy. Finally, the implication of these results for intervention directed to optimizing early adult-child interactions are addressed.     

Questionnaire de sensibilité au rejet : qualités psychométriques de la traduction française de l’Adult Rejection Sensitivity Questionnaire (ARSQ)

IntroductionExacerbated rejection sensitivity is a psychological process strongly present in certain personality disorders. Berenson et al. (2013) developed the Adult Rejection Sensitivity Questionnaire (A-RSQ), which evaluates the anxious expectation of perceived rejection by people close to them.ObjectiveThe purpose of our study was to investigate the psychometric qualities of a French version of the A-RSQ.MethodThis study was conducted with 140 French participants. The participants completed online our French translation of the A-RSQ and the Borderline Symptoms List (BSL-23), the Experiences in Close Relationships-Revised Questionnaire (ECR-R) and the Liebowitz Social Anxiety Scale Self-reported (LSAS-SR).ResultsThe internal validity of the A-RSQ is acceptable. The A-RSQ is positively and significantly correlated with the three reference scales: BSL-23, LSAS-SR and ECR-R. Factor analysis suggests a three-factor structure.ConclusionThis French version of the A-RSQ presents psychometric qualities comparable to its original version. This tool may be useful to researchers and clinicians interested in relationship problems, particularly in the context of borderline personality disorder where rejection sensitivity is a central process.     

心理干预的优先获益者——来自发展可塑性的研究证据

近些年, 发展可塑性领域出现两个新模型--差别易感性模型和优势敏感性模型, 两个模型均表明个体从积极环境中的获益具有差异性。而心理干预作为一种特殊的积极环境被引入到该领域的研究中。已有的研究已经发现一些证据表明, 具备某些特征的当事人从心理干预中获益更多。这些特征包括人格和气质类、遗传类和生理类。本质上, 这些研究在处理“什么对谁最有效”的问题, 但现有研究仅能部分回答这个问题。因此, 心理干预的效果差异有多少可归于这些易感特征, 是有待继续回答的问题。     

2~3岁儿童在分配情境下的公平敏感性

公平敏感性是指个体对感知到的公平和不公平的稳定而个性化的反应, 其表现为个体对公平的不同偏好。本研究旨在考察2~3岁儿童公平敏感性发展特点, 并进一步探究分配情境、分配数量和分配结果等因素对儿童公平敏感性的影响。实验1采用VOE范式, 在第三方任务情境下, 考察130名2~3岁儿童公平敏感性的发展特点, 结果发现在VOE范式下, 2~3岁儿童公平敏感性随着年龄增长而上升, 3岁~3岁3个月儿童的公平敏感性发展最明显。实验2, 选取60名处于公平敏感性发展最明显的3岁~3岁3个月的儿童比较其在不同分配情境、分配数量以及分配结果下的注视时间差异。结果表明, 在有接受者情境下儿童公平敏感性显著高于无接受者情境下的公平敏感性, 并且公平敏感性受分配数量的影响。     

从母亲的敏感性到学步儿的依恋安全性：内部工作模式的桥梁作用

采用视觉习惯化实验程序、陌生情境技术及母亲行为Q分类方法对41名14个月的学步儿及其母亲进行了学步儿内部工作模式、学步儿在陌生情境中的依恋类型以及母亲在母婴互动中的敏感性的评估。结果发现：(1)不安全型的学步儿预期看护者对他们痛苦的信号是无回应的。(2)以自身为中心的母亲的学步儿预期看护者是无回应的。(3)潜类别分析的结果发现母亲敏感性影响学步儿依恋行为的2种关系模式：类别1, 以孩子为中心的母亲的学步儿更容易形成看护者是有回应的预期, 持这种预期的学步儿在陌生情境程序中表现出安全依恋行为; 类别2, 以自身为中心的母亲养育出的学步儿更容易对看护者形成无回应的预期, 并在陌生情境中表现出不安全依恋行为。研究表明：内部工作模式在母亲的敏感性和学步儿的依恋安全性之间起着重要的内部机制作用—— 母亲的敏感性行为的累积促进了学步儿内部工作模式关于母亲的预期, 这种预期又进一步引导着学步儿的依恋行为。     

低家庭社会阶层大学生为何更容易社交焦虑？——心理社会资源和拒绝敏感性的多重中介作用

在阶层的社会认知理论和备用容量模型框架下,探讨心理社会资源、拒绝敏感性在家庭社会阶层与大学生社交焦虑间的多重中介作用。选取1400名在校大学生为被试,采用与积极心理变量结果相关度最高的乐观、控制感、自尊和外向性四种人格特质问卷作为心理社会资源的测量工具,同时施测了MacArthur主观社会阶层量表、拒绝敏感性问卷、Liebowitz社交焦虑量表,还收集了被试的父母亲职业、受教育程度及月收入水平等客观家庭社会阶层指标。Bootstrap中介效应检验结果表明,家庭社会阶层显著负向预测大学生社交焦虑,心理社会资源水平、拒绝敏感性在二者间起到中介作用,同时家庭社会阶层还顺序性地通过先影响心理社会资源、再影响拒绝敏感性这一链式路径对社交焦虑产生影响。因此为了预防和干预低阶层大学生社交焦虑,未来可以考虑提升心理社会资源水平和降低拒绝威胁敏感性两种途径。
