Effect of goal difficulty and feedback seeking on goal attainment and learning1

Abstract: This field study investigated the effect of goal difficulty and feedback seeking on goal attainment and learning in Management by Objectives (MBO) programs. Participants (n = 105) described the degree of their goal difficulty. After 6 months, they answered a questionnaire that inquired about the frequency of the feedback‐seeking and the degree of learning during the 6‐month period. Data about the extent of goal attainment were obtained from the participants’ immediate supervisors. The results indicated that goal difficulty and the frequency of feedback seeking were positively related to the degree of goal attainment and learning.     

工作记忆训练及对数学能力的迁移作用

工作记忆缺陷会影响个体数学能力发展。通过记忆策略、广度、刷新、转换等功能的工作记忆训练,可以改善个体认知功能。然而,工作记忆训练对个体的阅读、数学、流体智力等方面的远迁移效果并不一致。研究表明,工作记忆训练可以改善数感、视觉空间能力、推理能力等数学一般技能;也会通过改善语音工作记忆以及空间能力促进数学计算能力,或者通过改善中央执行系统,提升数学问题表征、模式识别、解题迁移、策略选择等复杂的过程,从而促进数学问题解决能力。因此,区分不同数学任务的认知过程,可以获得工作记忆训练对数学能力迁移效果的进一步证据。今后,神经影像学的证据或许也是未来工作记忆训练对数学能力提高的又一佐证。     

中国心理健康服务从业者的职业压力现状及影响因素

本研究目的是考察心理健康从业者的压力现状及其影响因素。769名来自全国20个省份的心理健康从业者填写了研究者自编的有93个多项选择题和填空题的问卷,其中2个从本问卷中抽取的5点量表具有可接受的心理测量学指标。主因素分析表明,心理健康从业者的职业压力可分为三类:专业能力不足、缺乏单位支持、工作负担过重。回归分析表明:影响职业压力的非专业因素有:年龄,性别,教育水平,全职或兼职,场所是否专用,以及每周咨询的小时数。在专业因素中,督导和培训能显著地缓解心理健康从业者的职业压力。治疗中的困难情况会显著地引发心理健康从业者的职业压力。     

数学学习困难儿童的编码加工特点:基于PASS理论的研究

同时加工和继时加工是PASS模型中的两类编码加工,二者在数学学习中发挥重要作用。使用基于PASS理论的认知评估系统（DN：CAS）单纯型数学困难、混合型数学困难和正常小学生进行两类编码加工的测评,比较研究发现,两类困难学生的两类编码加工水平均显著低于正常儿童,两类困难学生间的同时加工差异不显著,而混合型困难学生的继时加工水平显著低于单纯型困难学生。较低的同时加工水平似乎是两类数学困难的共同特征,继时加工水平的差异则似可作为单纯型与混合型困难的区分指标之一。     

学困生关于材料特征的元认知知识与应用的实验研究

本研究以62名学习困难学生(以下简称差生或学困生)和63名优生为被试,采用三因素混合实验设计,对优差生的阅读元认知知识及其应用特点进行了研究。结果表明：(1)优生对材料组织特征的元认知知识水平显著高于对词汇难度特征的元认知知识水平,而差生不存在显著差异;(2)九年级学生对材料组织特征的元认知知识水平显著高于词汇难度特征的元认知知识水平;其他年级之间没有显著差异;(3)在实际的阅读过程中,优生进行时间分配的人数显著多于学困生;学习困难学生的元认知知识与元认知控制的联系显著弱于优生。     

Multiple paths to transfer and constraint relaxation in insight problem solving

In two experiments participants received various training methods designed to relax constraints present in the Four-Tree problem (deBono, 1967 deBono, E. 1967. The use of lateral thinking, London: Jonathan Cape.  [Google Scholar]), a difficult insight problem. Geometry misconceptions were corrected via direct instruction. Participants’ difficulty with developing three-dimensional representations was addressed via spontaneous analogical transfer (Experiment 1) or via cued analogical transfer (Experiment 2). We found that, while both training methods were effective, alleviating multiple constraints was more effective than the alleviation of single constraints via training programmes (c.f.

Effects of Item Difficulty on the Retrieval of Solutions during Cognitive Skill Acquisition: Age Differences

ABSTRACT

In cognitive skill learning, shifts to better strategies for obtaining solutions often occur while associations between problems and solutions are being strengthened. In two skill learning experiments, we examined the effects of item difficulty on the retrieval of solutions and the learning of problem–solution associations in younger and older adults. The results of both experiments demonstrated an ‘easy effect’ in both younger and older adults, such that the retrieval of solutions as well recognition memory for problems was best for the easier items. In addition, a ‘hard effect’ was found in younger adults, but not in older adults, whereby the retrieval of solutions as well as recognition memory for problems was better for harder items than for medium-difficulty items. The finding that increased computational demands at the item level delayed item memorization and the retrieval of solutions in older adults but not younger adults is consistent with a general-resources account of age-related differences in skill learning.     

Predictors of student burnout and engagement among university students

This study investigated influences of core self-evaluation traits, career decision-making difficulties and social support on student burnout and engagement. A cross-sectional design was used with a non-probability quota sample. In the multiple regression analyses, self-efficacy, inconsistent information due to internal conflict and (lack of) parental support were significant predictors of exhaustion, cynicism, vigour and dedication. Self-esteem was also a significant predictor for the two engagement dimensions. In addition, lack of information about the self, lack of information about the occupations and inconsistent information due to external conflict predicted cynicism.     

Different routes to metacognitive judgments: The role of accuracy motivation

The current research proposes that metacognitive difficulty affects product evaluation through two different routes—the feelings of ease-of-retrieval heuristic and the self-validation process. The findings across four laboratory experiments show that metacognitive difficulty can undermine product evaluation through the feelings of ease-of-retrieval heuristic among low-accuracy individuals, regardless of a perceived fit between expected and experienced difficulty. In contrast, the findings indicate that metacognitive difficulty can enhance (vs. undermine) product evaluation among high-accuracy individuals through the self-validation process when there is a perceived fit (vs. misfit) between expected and experienced difficulty. We suggest that individuals under high accuracy motivation are more likely than those under low accuracy motivation to draw less determined and more flexible interpretation of metacognitive difficulty in making their product evaluation.
