Intact Procedural Knowledge in Patients with Alzheimer's Disease: Evidence from Golf Putting

Can Alzheimer's disease (AD) patients efficiently learn to perform a complex motor skill when relying on procedural knowledge? To address this question, the authors compared the golf-putting performance of AD patients, older adults, and younger adults in 2 different learning situations: one that promotes high error rates (thus increasing the reliance on declarative knowledge) or one that promotes low error rates (thus increasing the reliance on procedural knowledge). Motor performance was poorer overall for AD patients and older adults relative to younger adults in the high-error condition but equivalent between similar groups in the low-error condition. Also, AD patients in the low-error condition had better performance at the final putting distance relative to those in the high-error condition. This performance facilitation for AD patients likely stems from intact procedural knowledge.     

Feedback influences children's reasoning about math equivalence: A meta-analytic review

ABSTRACT

Decades of research have focused on children's reasoning about math equivalence problems for both practical and theoretical insights. Not only are math equivalence problems foundational in arithmetic and algebra, they also represent a class of problems on which children's thinking is resistant to change. Feedback is one instructional tool that can serve as a key trigger of cognitive change. In this paper, we review all experimental studies (N = 8) on the effects of feedback on children's (ages 6–11) understanding of math equivalence. Meta-analytic results indicate that feedback has positive effects for low-knowledge learners and negative effects for high-knowledge learners, and these effects are stronger for procedural outcomes than conceptual outcomes. Findings highlight the variable influences of feedback on math equivalence understanding and suggest that models of thinking and reasoning need to consider learner characteristics, learning outcomes, and learning materials, as well as the dynamic interactions among them.     

How does supervisor-focused procedural justice explain the effects of person-focused leadership? The moderating role of leader-referenced relational-self

This study examines how the supervisor-focused procedural justice (SPJ) mediates the effect of benevolent paternalistic leadership on supervisor-directed organizational citizenship behaviour (OCBS) across employees with different types of leader-referenced relational-self. We use leader identification and traditionality to operationalize the concept of leader-referenced relational-self. Significant three-way interaction effects in both the leadership-SPJ and the SPJ–OCBS relationships are found. The SPJ-mediated effect of benevolent paternalistic leadership on OCBS is significant among employees whose leader identification and traditionality range from average to high levels. The findings suggest that leader-referenced relational-self is more complex than leader identification. Limitations, the implications for theory, research, and practice are discussed.     

The role of inhibition and speed of processing in mathematics

The current study highlights the importance of inhibitory ability in facilitating performance in mathematics. To understand the role of inhibition in mathematical knowledge, this study tested 102 college students on a series of standardized complex math exercises. Inhibition tasks varied by task and stimuli (letters, numbers, and arrows). The result showed stronger associations between math abilities and strength of inhibition with more inhibition found for the flanker task (involving inhibition of peripheral stimuli) than for the Navon task (requiring inhibition of a potential response). The results supported the view that Inhibition in general (which is not unique to numerical stimuli) is associated with math abilities. General, rather than specific inhibition was associated with math abilities and finally, speed of processing masked the relationship between math and inhibition. These results confirm the assumption that the relation between inhibition and math performance is modulated by the task that measures the inhibition, and by additional predictors such as processing speed.     

社会公平感、机构信任度与公共合作意向

社会公平从古至今都是人类追求的崇高社会理想。对社会公平的感知即社会公平感直接决定着个体的机构信任,并影响其公共合作参与。本研究将社会公平感分为分配公平和程序公平,将机构信任度分为工具信任和动机信任,采用实验室情境设计的方法,引入最后通牒博弈和免责博弈范式,通过2个实验系统探讨"公正无私,一言而万民齐"的因果机制。研究发现分配公平与程序公平正作用于个体的公共合作态度与意向,在此基础上建立起公共合作的双路径模型:外部路径由分配公平产生工具信任和动机信任,进而触发公共合作;内部路径由程序公平产生动机信任和工具信任,进而触发公共合作;二者结合构成个体参与公共合作的双动力系统。双路径模型的适用性在组织情境和社会情境下均得到了支持。     

程序公正、不确定性对公共政策可接受性的影响:情感信任、认知信任的中介作用

为了研究程序公正、不确定性与公共政策可接受性之间的关系,并进一步考察情感信任和认知信任在其中的中介效应,本研究选取公共政策领域,通过问卷调查的方法随机选取510名北京市民进行研究。研究发现,程序公正与公共政策可接受性正相关,不确定性与公共政策可接受性负相关,情感信任中介程序公正与公共政策可接受性,并对不确定性与公共政策可接受性之间有遮掩效应,而认知信任不存在显著的中介作用。     

The role of behavioral mind‐sets in goal‐directed activity: Conceptual underpinnings and empirical evidence

The cognitive and motor behavior that people perform in the course of pursuing a goal can induce a mind-set that persists to influence the strategy they use to attain very different goals in unrelated situations. Although the strategies governed by a mind-set are typically applied consciously and deliberately, they are performed without awareness of the reasons for their selection. Research in both social psychology and consumer behavior exemplifies the impact of mind-sets on comprehension, judgments, and decision making, thus providing evidence of the scope and diversity of their effects.     

程序公正的测量及研究操纵

程序公正是指处理管理事务所依据的原则是否公正。普遍认可的程序公正原则包括一致性、避免偏见、准确性、可修正、代表性、道德与伦理原则。程序公正研究主要有测量和实验操纵两种研究范式。对程序公正的测量主要以单维为主,亦有少数多维测量量表;对程序公正的实验操纵主要以发言权为主,有少数研究对准确性、无偏性或综合几项原则进行操纵。未来研究应考虑程序公正的结构问题,对程序公正的操纵范围进行扩展、操纵方法考虑情景性,还需关注程序公正与程序不公正的差异。     

Whose memories are they and where do they go? Problems surrounding internalization in children on the autistic spectrum

Recent work in neuroscience has highlighted the contrast between 'procedural' memory for bodily experiences and skills, which is unconscious though unrepressed, and verbalizable, 'declarative' memory, which includes autobiographical memory. Autobiographical memory is weak in people with autistic spectrum disorder, who frequently turn to self-generated sensations for reassurance that they continue to exist. The author suggests that, instead of internalizing shared experiences leading to growth, children with autism can feel that they add to themselves by taking over the qualities of others through the 'annexation' of physical properties that leads to a damaged object and can trigger a particular sort of negative therapeutic reaction. Clinical illustrations drawn from the treatment of two children on the autistic spectrum illustrate some ramifications of these processes in relation to the sense of a separate identity and the capacity to access memories.     

Procedural Text Structure and Reader Perceptions and Performance

This research tested the relationship between text structural variables (on vs. off the causal chain, active vs. static information, and hierarchical structure) and reader perceptions, reading time, and true-false performance for procedural texts. Twenty-four college-age participants each read 3 procedural texts. As predicted, sentences that were (a) on the causal chain, (b) active, and (c) associated with task steps were read more slowly and judged to be more important (p < .05). The results were similar to those previously found with narratives, except for the hierarchical structure variable. Also as predicted, text differences were found such that as the variation in the type of information contained in the text increased, relationships with the structural variables increased.
