学习策略在思维风格与数学学业成就关系中的中介效应研究

以227名大学二年级理科生为被试,采用问卷调查法,探讨了学习策略在思维风格与数学学业成就关系中的作用。结果表明：（1）认知策略、元认知策略在等级制风格与数学学业成就关系中起完全中介的作用,而资源管理策略在等级制风格与数学学业成就间的中介效应不显著。（2）认知策略、元认知策略在整体性风格与数学学业成就关系中起部分中介的作用,而资源管理策略在整体性风格与数学学业成就间的中介效应不显著。（3）认知策略、元认知策略和资源管理策略在开放性风格与数学学业成就关系中起部分中介的作用。（4）元认知策略在等级制风格与数学学业成就间的中介作用以及在开放性风格与数学学业成就间的中介作用都是相对较大的。     

学优儿童学习适应性、学习习惯和应试技能及其关系

采用《儿童学习适应性调查表（I）、（II）》和《学习习惯与应试技能自我测查表》对231名学优儿童的学习适应性及其相关因素进行调查。结果表明：（1）学优儿童和学习不良儿童的学习适应性、学习习惯和应试技能存在显著性差异;（2）城市学优儿童的学习生活、学习习惯、学习方法、阅读习惯和技能明显优于农村学优儿童;（3）学优女生在学习适应性明显好于男生,但女生有独立性差、情绪障碍等症状,而学优男生则在学习习惯方面不如女生。在学习习惯与应试技能方面则不存在显著的性别差异;（4）除了对学校的态度因子外,学优儿童学习适应性与其学习习惯和学习方法、阅读习惯和技能、准备与应试等有显著性相关。     

On Learnability of Restricted Classes of Categorial Grammars

In this paper we present learning algorithms for classes of categorial grammars restricted by negative constraints. We modify learning functions of Kanazawa [10] and apply them to these classes of grammars. We also prove the learnability of intersection of the class of minimal grammars with the class of k-valued grammars. Presented by Wojciech Buszkowski     

Learning from Spiritual Models and Meditation: A Randomized Evaluation of a College Course

Effects of two meditation and mindfulness-based spiritual interventions were examined in college undergraduates (N=44). Compared to a control group, both interventions decreased negative religious coping (d=−0.80, p<.01) and images of God as mainly controlling (d=−.73, p<.01). One intervention provided more training in tools for learning from community and tradition-based spiritual exemplars. It produced gains in famous or traditional spiritual exemplars’ perceived influence (d=+.81, p<.05) and availability (d=+.66, p<.10), in self-efficacy for learning from spiritual exemplars (d=+.92, p<.05), and in nonmaterialistic aspirations (d=+0.65, p<.05).     

Cognitive imitation in typically-developing 3- and 4-year olds and individuals with autism

Individuals diagnosed with autism suffer from numerous social, affective and linguistic impairments. It has also been suggested that they have a global imitation deficit. That hypothesis, however, is compromised by the fact that individuals with autism suffer from various motor impairments. Here we describe an experiment on cognitive imitation, a type of imitation that doesn’t require motor learning. Nine male autistic subjects and 20 typically-developing 3- and 4-year olds were trained to respond, in a prescribed order, to different lists of photographs that were displayed simultaneously on a touch-sensitive monitor. Because the position of the photographs varied randomly from trial to trial, sequences could not be learned by motor imitation. In three different imitation treatments, including a ghost control, autistic subjects learned new sequences more rapidly after observing a model execute those sequences than when they had to learn new sequences entirely by trial and error. Moreover, the performance of autistic subjects did not significantly differ from the performance of typically-developing controls. The result of this and other studies suggests that individuals with autism suffer from a specific novel motor imitation deficit.     

Beyond stop consonants: Consonantal specificity in early lexical acquisition

Previous research has shown that 20-month-old infants can simultaneously learn two words that only differ by one of their consonants, but fail to do so when the words differ only by one of their vowels. This asymmetry was interpreted as developmental evidence for the proposal that consonants play a more important role than vowels in lexical specification. However, the consonant/vowel distinction was confounded with another distinction, that of the continuous status of the phonemes used (discontinuous stop consonants versus continuous vowels). The present study investigated 20-month-olds’ use of phonetic specificity while simultaneously learning two words that differ by a continuous consonant. The results obtained parallel those previously found for stop consonants, confirming the original claim of an asymmetry between the roles of consonants and vowels at the lexical level.     

Auditory-Processing Malleability: Focus on Language and Music

ABSTRACT— Auditory processing forms the basis of humans' ability to engage in complex behaviors such as understanding spoken language or playing a musical instrument. Auditory processing is not a rigid, encapsulated process; rather, it interacts intimately with other neural systems and is affected by experience, environmental influences, and active training. Auditory processing is related to language and cognitive function, and impaired auditory processing negatively affects the quality of life of many people. Recent studies suggest that the malleability of the auditory system may be used to study the interaction between sensory and cognitive processes and to enhance human well-being.     

Increasing Retention Without Increasing Study Time

ABSTRACT— Because people forget much of what they learn, students could benefit from learning strategies that yield long-lasting knowledge. Yet surprisingly little is known about how long-term retention is most efficiently achieved. Here we examine how retention is affected by two variables: the duration of a study session and the temporal distribution of study time across multiple sessions. Our results suggest that a single session devoted to the study of some material should continue long enough to ensure that mastery is achieved but that immediate further study of the same material is an inefficient use of time. Our data also show that the benefit of distributing a fixed amount of study time across two study sessions—the spacing effect —depends jointly on the interval between study sessions and the interval between study and test. We discuss the practical implications of both findings, especially in regard to mathematics learning.     

学习能力、知识经验对儿童问题解决的影响

采用问题解决类比任务范式,考察了学习能力、知识经验对90名小学4年级儿童在问题解决过程中类比问题解决及策略运用的影响。结果发现:(1)在问题解决的质量上,学习能力具有显著制约作用,学习能力越高,问题解决成绩越好,而知识经验作用不显著;在问题解决速度上,学习能力和知识经验作用均不显著。(2)学习能力对问题解决策略运用的总体分布、高级类比和非类比策略运用具有显著性作用。(3)不同知识经验对策略运用总体分布及高级类比策略有显著性作用。
