Intergroup helping behavior by high status group members typically functions to support and further entrench systems of social hierarchy (Nadler, 2002). This research examined whether the virtue of generosity could increase support for more egalitarian group relations, as indexed by reduced social dominance orientation (SDO; Pratto, Sidanius, Stallworth, & Malle, 1994). Pilot testing (N = 367) revealed a negative relationship between self-reported generosity and SDO. In Study 1, two long-term experimental manipulations of generosity in 110 college students reduced SDO. One manipulation involved a nine week community service learning project, and the other involved a five-part reflection paper assignment on generous individuals. In Study 2, a brief generosity prime in 58 college students reduced SDO scores. The potential benefits of targeting SDO directly, and the importance of examining the motives behind generosity are discussed.  相似文献

Previous research has shown that rats can learn matching-to-sample relations with olfactory stimuli; however, the specific characteristics of this relational control are unclear. In Experiment 1, 6 rats were trained to either match or nonmatch to sample in a modified operant chamber using common household spices as olfactory stimuli. After matching or nonmatching training with 10 exemplars, the contingencies were reversed with five new stimuli such that subjects trained on matching were shifted to nonmatching and vice versa. Following these reversed contingencies, the effects of the original training persisted for many trials with new exemplars. In Experiment 2, 9 rats were trained with matching procedures in an arena that provided for 18 different spatial locations for comparison stimuli. Five subjects were trained with differential reinforcement outcomes and 4 with only one type of reinforcer. Differential outcomes and multiple exemplars facilitated learning, and there was strong evidence for generalization to new stimuli for most rats that acquired several conditional discriminations. Performances with novel samples were generally above chance, but rarely reached the high levels obtained during baseline with well-trained stimulus relations. However, taken together, the data from the two experiments extend previous work, show that rats can learn both match and nonmatch relations with different experimental protocols, and demonstrate generalization to novel sample stimuli.  相似文献

Two studies were carried out in order to better understand the role of perceptual and visuo-motor skills in handwriting. Two training programs, visual-haptic (VH) and visual (V), were compared which differed in the way children explored the letters. The results revealed that improvements of VH training on letter recognition and handwriting quality were higher than improvements after V training. We suppose that VH training was more efficient because it improved both perceptual and visuo-motor skills. In the second experiment, in order to investigate the part of each component, we assessed the link between visuo-motor skills, perceptual skills and handwriting. The results showed that only the visuo-motor tasks predict handwriting copying performance. These results are discussed in relation to the respective roles of the perceptual and visuo-motor skills on letter shape learning and handwriting movement execution.  相似文献

The purpose of the present study was to predict and explain the academic cheating behaviors of elementary school students with learning disabilities (LD) by applying the cusp catastrophe model. Participants were 32 students with identified LD from state governmental agencies although all both them and the typical students participated in the experimental manipulation (N = 480). Academic cheating was assessed using an empirical paradigm where true achievement was subtracted from achievement in a test without proper invigilation. Data analysis supported the proposed cusp catastrophe models, where mastery-related motives acted as asymmetry and performance goals as bifurcation variables respectively. These findings were confirmed with application of the interactive goal hypothesis (Barron & Harackiewicz, 2001), where the interactive approach and avoidance performance goal term functioned as a splitting factor in the relationship between adaptive motivation and performance.  相似文献

IntroductionThe overall goal of the study was to draw, in French language, a complete picture of spelling abilities in young students with SLI, enrolling in ordinary classes.ObjectiveThe main aim was to show how the developmental trajectories of lexical spelling and the morphological spelling are different when a large age span is observed (7 to 18 years old).MethodsThe spelling abilities were evaluated through a narrative communicative. Two groups of students with SLI (7–11 years and 12–18 years) were compared with two groups of typical students matched on chronological age.ResultsThe lexical spelling was acquired before the morphological spelling for SLI and typical participants. At 12–18 of age, the SLI participants did not produce more lexical errors than the typical group. For the lexical spelling, at 7–11 years, the SLI participants had a specific difficulty with the segmentation of the words: they produced words that do not exist in the language and which by definition have no morphological markers.ConclusionThe SLI participants need more time to learn than the typical participants. At 7–11 years, before learning of morphology, they must be able to control segmentation the segmentation of words. The low number of morphological errors in the school SLI group of 7–11 years is not necessarily a sign of difficulty. The increase in the number of errors at 12–18 years is the sign that this problem has been exceeded and that the learning of the written morphological markers can really begin.  相似文献

The interest to research spirituality in the classroom has been constant over the last decade. However, empirical research into classroom pedagogy and the lived experience of religious education has been scarce. This study describes a small-scale intervention that aimed to promote students’ spiritual reflection in Finnish upper secondary school RE classes by using stimulating tasks. One class (N?=?23) of upper secondary school students (16–18?years of age) participated in the study. Analysis of students’ responses after the silent reflection moments suggested that the tasks were successful in eliciting some level of spiritual reflection for most of the students. In this article, we describe the experiment and the content and nature of this reflection, as well as discuss the advantages and challenges of spiritually sensitive teaching methods in a classroom of heterogeneous worldviews.  相似文献

采用累积生态风险问卷、消极自我图式问卷、网络成瘾问卷以及学习倦怠问卷对湖南省4所高职院校的664名高职生进行调查,考察累积生态风险与高职生学习倦怠的关系以及消极自我图式、网络成瘾的中介作用。结果发现:(1)高职生累积生态风险、消极自我图式、网络成瘾和学习倦怠均呈显著正相关;(2)高职生累积生态风险对学习倦怠的直接效应和间接效应均显著。间接效应包括了三条路径:通过消极自我图式的中介作用、通过网络成瘾的中介作用以及通过消极自我图式和网络成瘾的链式中介作用。这一结论有助于理解累积生态风险对学习倦怠的作用机制,为降低高职生的学习倦怠提供参考建议。  相似文献

教育心理学中的分段原则认为,将视频学习材料分割成几个小片段进行学习的效果更好。以往关于分段的研究通过两个角度的操纵考察了分段在学习中的作用,一方面是交互性角度,学习者自己控制的分段及系统分段;另一方面是结构性角度,分段是在任意时间点划分和有意义时间点上划分。通过对以往研究结果的整理发现,大部分研究证明分段学习相较于连续学习的成绩更好,并且能降低学习者在学习过程中的感知难度, 提高积极的情感状态,但是对心理努力的影响比较微弱。研究者们从事件分割理论和认知负荷理论的视角对分段的效果做出了解释。未来研究需要继续关注分段的边界条件、拓宽研究的范围、探究分段的认知神经基础等不断完善分段原则在教学中的应用。  相似文献

利用眼动分析技术,通过设置不同难度和分值的计算项目,探讨了在有时间压力下学习者的学习时间分配。结果发现:(1)在首次项目选择上,学习者优先选择学习率最高的项目;(2)在学习过程中,学习者的项目选择次序也是根据学习率由高到低。总之,在学习时间分配上,如果需要权衡难度与分值,学习者会考虑单位时间的获益,也就是以学习率为议程的主要依据。研究不仅利用眼动分析技术证实了基于议程的学习时间分配模型,而且进一步揭示了学习率是设置学习时间分配议程的重要依据。  相似文献

离线阶段发生的学习被称为离线巩固, 即在最初获得知识之后, 即使没有额外的练习, 其记忆痕迹也会保持稳定或提高。有研究初步探究了睡眠对知觉和动作序列内隐学习离线巩固的影响, 然而, 这些研究未能实现知觉序列与动作序列的完全分离, 序列类型是否调节睡眠对内隐序列学习离线巩固的影响仍需进一步探讨。此外, 既往外显学习的研究发现相对于简单的序列, 复杂的序列更容易从睡眠中获益, 表现出基于睡眠的离线巩固效应。睡眠对知觉序列与动作序列内隐学习离线巩固的影响是否会受到序列复杂程度的调节尚不明确。为此, 本研究在完全分离知觉序列和动作序列的情况下, 通过3个实验操纵序列的长度及结构, 设置3种不同复杂程度的序列规则, 考察了这一问题。结果发现, 对于动作序列, 序列规则复杂程度较低时, 无论是否经过睡眠都会发生离线巩固效应, 而当动作序列规则较为复杂时, 只有经历睡眠才会引起离线巩固效应; 对于知觉序列, 无论何种难易程度的规则, 均未发生离线巩固效应。上述结果表明内隐序列知识基于睡眠的离线巩固会受到序列类型及序列复杂程度的调节, 这为内隐学习的离线巩固争论提供了新的视角。  相似文献
