三种压力与创意自我效能感对创造力的影响

以216名初中二年级学生为被试,采用现场实验,探讨个体创意自我效能感在竞争、评价和时间三种压力情境下对创造力的影响。结果发现,三种压力对于总体创造力的影响不同;时间、评价压力分别提高了流畅性和新颖性,竞争压力既提高了流畅性又提高了新颖性,但三种压力情境都降低了变通性;创意自我效能感中间组的学生在压力情境下具有最好的变通表现,而效能感低分组表现最差。     

记叙文阅读中人物第一印象的即时更新

采用移动窗口技术探讨读者在记叙文阅读中是否对人物第一印象进行即时更新。实验1探讨读者在阅读过程中是否会根据第一印象建构人物特征情境模型。实验2探讨已经形成的人物特征情境模型是否会受最近印象的影响得以更新。实验3探讨在明确描述人物特征的情况下,读者是否仍然会更新人物特征情境模型。研究结果表明,记叙文阅读中,读者会对人物第一印象进行即时更新,表现出首因效应向近因效应的转化。     

背景音乐的节奏与歌词语言熟悉程度对驾驶行为和眼动的影响

摘要：采用3D模拟驾驶情景结合眼动技术探讨音乐节奏和歌词语言熟悉程度对驾驶行为和眼动规律的影响,研究结果表明：（1）驾驶经验对驾驶行为及眼动影响显著,新手与老手相比速度更慢、错误数更多;（2）音乐节奏对驾驶速度、眼跳和垂直搜索广度影响显著,快节奏与慢节奏相比,驾驶速度更快、平均眼跳距离更短、垂直搜索广度更短;（3）歌词语言熟悉程度对驾驶速度、错误数和平均注视时间影响显著,熟悉语言与陌生语言相比,驾驶速度更慢、错误数更多、平均注视时间新手更长,老手无影响。（4）节奏与语言共同影响驾驶过程中的水平搜索广度,陌生语言时快节奏的水平搜索广度高于慢节奏,熟悉语言时快节奏的水平搜索广度低于慢节奏。通过本实验,建议驾驶员在选择音乐时选择陌生语言歌词的音乐,音乐节奏则可视情况而定。

Negations in syllogistic reasoning: Evidence for a heuristic–analytic conflict

Research indicates that cognitive age differences can be influenced by metacognitive factors. This research has generally focused on simple memory tasks. Age differences in working memory (WM) performance are pronounced, but are typically attributed to basic cognitive deficits rather than metacognitive factors. However, WM performance can be influenced by strategic behaviour that might be driven by metacognitive monitoring. In the current project, we attempted to connect these lines of research by examining age differences in metacognitive WM monitoring and strategies. In Experiment 1, younger and older adult participants completed a computerized operation span task in conditions that either required or did not require monitoring reports. Participants in the monitoring condition predicted and postdicted global performance for each block and rated their responses following each trial within a block. In Experiment 2, participants also reported their trial-level strategic approach. In contrast to the age equivalence typically found for simple memory monitoring, results demonstrated age differences in WM monitoring accuracy. Overall age differences in strategy use were not found, but using effective strategies benefited older adults' performance more than younger adults'. Furthermore, age-related differences in the WM task appear to be mediated by the accuracy of performance monitoring.     

Context effects and selective response lengthening in a temporal serial reproduction task

Repeatedly performing a temporal reproduction task has been reported to increase reproduced durations. We report the novel finding that the second reproduction in a series is selectively enhanced relative to the first. This was true regardless of whether the responses were discrete (separate start and stop responses) or contiguous (stop response is the start of the next response). In a final experiment we test the hypothesis that the second reproduction is more influenced by the central tendency of previously experienced durations than is the first. These results are discussed in terms of two sources of performance uncertainty: temporal remoteness of the second and subsequent reproductions from the standard and trial-by-trial unpredictability of the standard in random but not blocked designs.     

Why it is difficult to see the anima as a helpful object: critique and clinical relevance of the theory of archetypes

This paper is divided into three parts. The first deals briefly with more general aspects of the theory of archetypes (as conceived by Jung); the second examines the anima archetype in rather more detail, because it is, apart from the self, the main archetype in Jung's thought; and the third discusses the clinical repercussions of the anima theory and of the theory of the archetypes in general. The various references to Jung himself and certain circumstances of his life are included here on the assumption that personal problems in his biography contributed decisively to the constitution of his theory, so that deeper insights accure if they are taken into account.     

On Categorical Equivalences of Commutative BCK-algebras

A commutative BCK-algebra with the relative cancellation property is a commutative BCK-algebra (X;*,0) which satisfies the condition: if a ≤ x, a ≤ y and x * a = y * a, then x = y. Such BCK-algebras form a variety, and the category of these BCK-algebras is categorically equivalent to the category of Abelian ℓ-groups whose objects are pairs (G, G ₀), where G is an Abelian ℓ-group, G ₀ is a subset of the positive cone generating G ⁺ such that if u, v ∈ G ₀, then 0 ∨ (u - v) ∈ G ₀, and morphisms are ℓ-group homomorphisms h: (G, G ₀) → (G′,G′₀) with f(G ₀) ⫅ G′₀. Our methods in particular cases give known categorical equivalences of Cornish for conical BCK-algebras and of Mundici for bounded commutative BCK-algebras (= MV-algebras).
