The explicit learning of new names for known objects is improved by dexamphetamine

A randomised, double-blind, placebo-controlled, between subjects study design (N=37) was used to investigate the effects of dexamphetamine on explicit new name learning. Participants ingested 10mg of dexamphetamine or placebo daily over 5 consecutive mornings before learning new names for 50 familiar objects plus fillers. The dexamphetamine group recognised and recalled the new names more accurately than the placebo group over the 5 days and 1 month later. Word learning success was not associated with baseline neuropsychological performance, mood, cardiovascular arousal, or sustained attention. These results may have implications for the pharmacological treatment of acquired naming difficulties.     

Psychosocial factors and reading difficulties: students with reading difficulties drawn from a representative population sample

In a representative sample of 2,464 Norwegian adolescents, aged 12-15 years, 7.8% (n= 191) reported reading difficulties (RD). No gender difference was found. Adolescents with RD were compared to classmates on psychosocial variables. In univariate analysis, RD adolescents report higher levels of depressive symptoms, more school stress, worried more about going to school, had lower school grades and lower attachment to parents than those without RD. They also scored lower on Global Self-worth and on Social Acceptance scales. Further, they reported reduced levels of psycho-functioning during the previous year because of mental health problems, they had received more help and had used more medication for such problems. In a multivariate logistic regression analysis, receiving help for mental health problems and reduced psycho-functioning showed the strongest associations with student RD status. No gender interactions were found. The study demonstrated important differences between adolescents with and without RD.     

Elaborative processing in the Korsakoff syndrome: context versus habit

Using a procedure of Hay and Jacoby [Hay, J. F., & Jacoby, L. L. (1999). Separating habit and recollection in young and older adults: Effects of elaborative processing and distinctiveness. Psychology and Aging, 14, 122–134], Korsakoff patients’ capacity to encode and retrieve elaborative, semantic information was investigated. Habits were created during initial training, whereupon cued-recall memory performance was examined, with habit opposing as well as facilitating recollection of earlier studied words. A first group of patients was instructed and tested in the same way as healthy controls and showed poor test performance. Nevertheless, when given more processing and response time, additional explanation, and explicit encouragement, a second group of patients performed similarly to healthy controls. The results suggest that, when given adequate support, Korsakoff patients are able to encode and make use of semantic, contextual, and sequential information. Word distinctiveness, however, only influenced performance of controls.     

“民族认同，国家认同”与青少年自尊的关系

自尊被普遍认为是青少年的发展中的一个重要因素,已有研究发现它与心理幸福感呈显著的正相关,并与沮丧和绝望呈显著的负相关。就是由于自尊的心理上的重要性,所以有大量的研究来探讨它的影响因素。大多数对自尊的研究主要关注的是个体的能力和人际问的经历来作为自尊主要成分。尽管自尊的个人资源明显是很重要的,但是这样的关注忽略了自尊的群体成员方面的影响。本文就是探讨群体认同,尤其是考察民族认同和更广层面的国家认同.对少数民族青少年自尊的预测。     

低自尊个体对拒绝性信息的注意偏向

自尊是个体对自我的情感性评价, 影响着个体对周围环境的应对方式。低自尊个体由于容易知觉到外部的拒绝性信息, 也更倾向于将别人的行为知觉为拒绝, 因而存在对拒绝性信息的注意偏向。本文首先综述了低自尊个体的认知与行为特点, 其次简单介绍了低自尊个体注意偏向的常用研究范式(Stroop范式、点探测任务、空间线索任务、惊吓探测范式、注意监测任务、注意转移任务), 随后列举了解释低自尊个体注意偏向的理论(社会计量理论、关系图式理论、注意成分说、注意控制说), 最后总结了低自尊个体注意偏向的脑机制研究。未来的研究应更多关注自尊结构的复杂性, 注意偏向的信息加工阶段性及其脑机制, 注意训练的作用机制及低自尊个体注意偏向的本土研究等问题。     

内隐自尊和风险偏好对大学生职业决策的影响

为研究影响大学生职业决策的影响因素和决策有效性,实验一、二分别从决策者心理特征（内隐自尊与风险偏好）和职业方案特征（框架效应与风险水平）入手,考察二者对大学生职业决策行为的影响。结果发现：内隐自尊和风险偏好的高低显著影响大学生择业倾向性;大学生对风险水平不同的职业方案的选择倾向由低到高依次为冒险、折中、保守方案;职业决策存在明显的框架效应。研究表明,大多数大学生倾向于选择保守的职业方案;高风险偏好的大学生倾向于选择冒险的职业方案;高内隐自尊大学生倾向于主动择业;积极表述的职业方案更受大学生所青睐。     

大学新生的羞怯、自尊与网络依赖的关系：交叉滞后分析

对361名大一新生进行为期3个月的追踪测量,以考察羞怯、自尊与网络依赖的发展变化及相互关系。结果发现：（1）大一新生的羞怯、自尊和网络依赖的水平具有一定程度的横向稳定性。（2）羞怯与网络依赖正相关,自尊与网络依赖负相关。（3）T1的网络依赖正向预测T2的羞怯,T2的羞怯正向预测T3的网络依赖;T1和T2的网络依赖分别负向预测T2和T3的自尊。结论：羞怯与网络依赖之间存在恶性循环,并且网络依赖会导致自尊水平的下降。     

政治技能与自我效能感对职业适应能力的影响——自尊的中介作用

本研究采用问卷调查法, 以492名高校大学生为研究对象,探索政治技能和自我效能感对大学生职业适应能力的影响及自尊的中介作用。结果表明：（1）政治技能和自我效能感对个体的职业适应能力有积极影响。（2）自尊在政治技能和职业适应能力之间,自我效能感与职业适应能力之间起着双重中介作用。     

Not all positive categories are alike: Exploring the superiority of the self as a positive source for associative attitude change via intersecting regularities

In associative evaluative learning, attitudes can originate from intersecting regularities between a target and both positive- and self-related stimuli. Liking for a focal target is primarily driven by its reference to one source, but it might be qualified by the reference to a contrast target. This contribution focuses on how the nature of positive and contrast sources affects learning via intersecting regularities. In two studies (N = 199 and N = 185), the self and another positive category lead to increased implicit and explicit liking, regardless of the contrast source's valence. In Study 3 (N = 128), confronting the self and the positive category in the same paradigm yields only implicit preferences for self-related targets. Both implicitly and explicitly, this preference for self- over positive-related target was moderated by self-positivity. Our findings confirm the robustness of learning via intersecting regularities and suggest that the self is a special evaluative source.
