Hiding in plain sight: Older U.S. purpose exemplars

ABSTRACT

Despite significant research on purpose in adolescence and early adulthood, little is known about purpose in older adults. This paper defines purpose as ongoing commitment to and sustained action toward goals that are meaningful to the self and aim to contribute beyond the self. This study of purpose in later life draws on interviews of 102 respondents drawn from a U.S. nationally representative sample of 1198 men and women aged 50–92. Eighteen interviewees are identified as exemplars of purpose beyond the self and are matched with a comparison group of non-purposeful peers. Interview coding revealed that, in contrast to the non-purposeful comparison group, the purpose exemplars describe their lives as including several interconnected sources of well-being: purpose beyond the self, positive relationships, positive life engagement, a sense of competence, and freedom balanced with the desire to contribute. Implications for practitioners and the public are discussed.     

The selective directed forgetting effect: Can people forget only part of a text?

Participants studied sentences describing two different characters and then were told to forget the sentences about only one of the characters. A second list contained sentences attributed to a third character. Subsequently, they received a recall test on the sentences about the original two characters. When the sentences could be thematically integrated, participants showed no directed forgetting relative to a control group that was never told to forget. However, with unrelated sentences, participants selectively forgot the target character's sentences without forgetting the other character's sentences. This selective directed forgetting effect is a novel empirical result. We interpret the results as consistent with Radvansky's (1999) ideas about inhibition with textual materials.     

初一学生英语单词记忆策略的训练研究

在初一学生英语单词学习中引入关键词和概念归类策略训练,探讨了记忆策略的训练效果和自我效能对英语单词记忆的影响。结果发现：两种策略训练都能显著提高初一学生英语单词扇一效果相近;关键词策略训练可显著提高低自我效能被试的自我效能感;记忆自我效能对英语单词记忆行为有显著影响,高自我效能被试在训练后英语单词记忆成绩更好。     

眼动分析法在学前儿童认知研究中的应用

眼动分析法是心理学研究的一种重要手段,它对于研究儿童的认知活动有着非常重要的意义。文章介绍了眼动记录的原理、眼动指标,并对该方法在研究学前儿童的图画观看、图文阅读、视觉搜索等领域的应用进行了评介。最后,对眼动分析法在学前儿童认知研究中的应用前景进行了展望。     

“位置法”记忆训练对改善儿童至老年时期的认知功能研究

本工作采用“位置法”对118例被试(包括儿童、少年、青年、中年和老年五个年龄组)进行记忆训练研究,分析不同年龄人记忆的发展变化和认知训练对改善记忆的作用,进而探讨发展的认知功能储备能量的年龄差异。结果表明:1.老年和儿童组各项成绩明显低于青、少年组;2.认知干预措施可在一定程度上改善老年人的记忆,再次证明老年智力和记忆有一定的可塑性。但在发展的储备能量和对图形的迁移效应中也存在与记忆相似的年龄差异。     

A latent class unfolding model for analyzing single stimulus preference ratings

A multidimensional unfolding model is developed that assumes that the subjects can be clustered into a small number of homogeneous groups or classes. The subjects that belong to the same group are represented by a single ideal point. Since it is not known in advance to which group of class a subject belongs, a mixture distribution model is formulated that can be considered as a latent class model for continuous single stimulus preference ratings. A GEM algorithm is described for estimating the parameters in the model. The M-step of the algorithm is based on a majorization procedure for updating the estimates of the spatial model parameters. A strategy for selecting the appropriate number of classes and the appropriate number of dimensions is proposed and fully illustrated on some artificial data. The latent class unfolding model is applied to political science data concerning party preferences from members of the Dutch Parliament. Finally, some possible extensions of the model are discussed.The first author is supported as Bevoegdverklaard Navorser of the Belgian Nationaal Fonds voor Wetenschappelijk Onderzoek. Part of this paper was presented at the Distancia meeting held in Rennes, France, June 1992.     

青少年父母监控现状研究

本研究从北京市两所普通中学的初一到高二年级中选取了1090名中学生为被试,采用问卷调查的方式,要求他们分别报告父亲和母亲的主、客观监控水平和监控手段(控制、沟通和搜寻),以探讨我国青少年父母监控的现状。经过(2)卡方检验、相关分析t、检验和方差分析,结果表明:(1)总体来讲,母亲在家庭里是青少年的主要监控者:母亲监控的客观水平高于父亲,并且母亲使用三种监控手段的情况均多于父亲;(2)女孩受到的父母监控超过男孩:母亲对女孩的客观监控水平高于男孩,并且母亲对女孩更多使用沟通手段;父母对女孩使用控制手段的情况超过男孩;(3)父母监控的年级差异并不明显,只有父母对初一学生会更多使用沟通手段;(4)父母对沟通手段和控制手段的使用都与客观监控水平呈正相关,但与主观监控水平呈负相关,而搜寻手段使用与监控水平之间的关系则跟沟通、控制手段相反;沟通手段对客观监控水平的正向预测力最强,搜寻手段对主观监控水平的正向预测力最强。     

Changing systems by changing individuals: the incubation approach to systems change

This article describes and evaluates the implementation of an innovative approach to systems change, the incubation approach, which was developed on a systems change project designed to increase the capacity of multiple systems (e.g., law enforcement, child protection, domestic violence, mental health, early education) to respond to children’s exposure to violence. The incubation approach encourages change agents to collaborate with project staff to gently nurture, or “incubate,” feasible and warranted change in target systems. Project staff gain concrete commitment from motivated and accessible change agents and collaborate with those agents to implement change actions. This approach works well with committed, executive-level change agents in target systems, with stable systems that have low turnover and well-integrated subsystems, and when seed funds are provided to key organizations.     

FINITE MODELS CONSTRUCTED FROM CANONICAL FORMULAS

This paper obtains the weak completeness and decidability results for standard systems of modal logic using models built from formulas themselves. This line of work began with Fine (Notre Dame J. Form. Log. 16:229–237, 1975). There are two ways in which our work advances on that paper: First, the definition of our models is mainly based on the relation Kozen and Parikh used in their proof of the completeness of PDL, see (Theor. Comp. Sci. 113–118, 1981). The point is to develop a general model-construction method based on this definition. We do this and thereby obtain the completeness of most of the standard modal systems, and in addition apply the method to some other systems of interest. None of the results use filtration, but in our final section we explore the connection.     

乳腺癌术式的演变及其最佳选择

乳腺癌作为女性常见的恶性肿瘤之一,一直是肿瘤学界研究的热点和焦点。手术作为其基本的治疗手段,术式几经改变。通过对乳腺癌术式演变的历史回顾,认为正是由于对乳腺癌生物学行为研究的不断深入,使得乳腺癌手术切除范围更趋于规范和科学。而由生物医学模式向生物—心理—社会医学模式的转变,以及循证医学(EBM)研究的开展,更促进了乳腺癌术式的不断改进,以最大程度减少并发症,获得更为满意的疗效。
