Reducing hopelessness: the interation of enhancing and depressogenic attributional styles for positive and negative life events among youth psychiatric inpatients

A recovery model of depression (Needles & Abramson, 1990 Journal of Abnormal Psychology, 99, 156-165) proposes that depressed individuals who exhibit an enhancing attributional style for positive events (i.e. make stable, global attributions) will be more likely to regain hopefulness and, thereby, recover from depression when positive events occur. While only a few studies have directly tested this model among clinical and nonclinical adult samples, none have tested a clinical sample of children and adolescents. Furthermore, prior studies testing this model have failed to examine the interactive role of an 'enhancing attributional style' for positive events with a 'depressogenic attributional style' for negative events, as prescribed by the hopelessness theory of depression (Abramson, Metalsky, & Alloy, 1989 Psychological Review, 96, 358-372). The current study presents data demonstrating that depressogenic and enhancing attributional styles interact to predict differential decreases in hopelessness. Implications of these findings and suggestions for future research also are presented.     

Memory development in the second year: for events or locations?

We employed an object-placement/object-removal design, inspired by recent work on 'episodic-like' memory in scrub jays (Clayton, N. S., & Dickinson, A. (1998). Episodic-like memory during cache recovery by scrub jays. Nature, 395, 272-274), to examine the possibility that children in the second year of life have event-based memories. In one task, a successful search could have been due to the recall of an object-removal event. In the second task, a successful search could only have been caused by recall of where objects were located. Success was general in the oldest group of children (21-25 months), while performance was broadly similar on the two tasks. The parsimonious interpretation of this outcome is that the first task was performed by location memory, not by event memory. We place these data in the context of object permanence development.     

A Mediated-Moderation Model of Maternal Parenting Style,Association with Deviant Peers,and Problem Behaviors in Urban African American and European American Adolescents

We examined a model positing that association with deviant peers mediates the relation between perceived maternal parenting style, represented by the dimensions demandingness, responsiveness, and their interaction, and problem behaviors in an urban sample of 82 African American and 56 European American young adolescents. Regression analyses revealed that the data are consistent with a model where association with deviant peers mediates the relation between maternal responsiveness and problem behaviors for European Americans and African American males. In addition, a responsiveness by demandingness interaction was found for European Americans. Only the relation between association with deviant peers and problem behaviors was supported for African American females. The results suggest that ethnic and gender variables might interact with pathways from parenting to association with deviant peers and problem behaviors and that the dimensions of parenting might not be equal in their salience.     

The relationship between object files and conscious perception

Object files (OFs) are hypothesized mid-level representations which mediate our conscious perception of persisting objects-e.g. telling us 'which went where'. Despite the appeal of the OF framework, not previous research has directly explored whether OFs do indeed correspond to conscious percepts. Here we present at least one case wherein conscious percepts of 'which went where' in dynamic ambiguous displays diverge from the analogous correspondence computed by the OF system. Observers viewed a 'bouncing/streaming' display in which two identical objects moved such that they could have either bounced off or streamed past each other. We measured two dependent variables: (1) an explicit report of perceived bouncing or streaming; and (2) an implicit 'object-specific preview benefit' (OSPB), wherein a 'preview' of information on a specific object speeds the recognition of that information at a later point when it appears again on the same object (compared to when it reappears on a different object), beyond display-wide priming. When the displays were manipulated such that observers had a strong bias to perceive streaming (on over 95% of the trials), there was nevertheless a strong OSPB in the opposite direction-such that the object files appeared to have 'bounced' even though the percept 'streamed'. Given that OSPBs have been taken as a hallmark of the operation of object files, the five experiments reported here suggest that in at least some specialized (and perhaps ecologically invalid) cases, conscious percepts of 'which went where' in dynamic ambiguous displays can diverge from the mapping computed by the object-file system.     

The role of language in acquiring object kind concepts in infancy

Four experiments investigated whether 9-month-old infants could use the presence of labels to help them establish a representation of two distinct objects in a complex object individuation task. We found that the presence of two distinct labels facilitated object individuation, but the presence of one label for both objects, two distinct tones, two distinct sounds, or two distinct emotional expressions did not. These findings suggest that language may play an important role in the acquisition of sortal/object kind concepts in infancy: words may serve as "essence placeholders". Implications for the relationship between language and conceptual development are discussed.     

Categorical perception of familiar objects

We report three experiments where the categorical perception of familiar, three-dimensional objects was investigated. A continuum of shape change between 15 pairs of objects was created and the images along the continuum were used as stimuli. In Experiment 1 participants were first required to discriminate pairs of images of objects that lay along the shape continuum. Then participants were asked to classify each morph-image into one of two pre-specified classes. We found evidence for categorical perception in some but not all of our object pairs. In Experiment 2 we varied the viewpoint of the objects in the discrimination task and found that effects of categorical perception generalized across changes in view. In Experiment 3 similarity ratings for each object pair were collected. These similarity scores correlated with the degree of perceptual categorization found for the object pairs. Our findings suggest that some familiar objects are perceived categorically and that categorical perception is closely tied to inter-object perceptual similarity.     

学生认知方式影响文章阅读理解的实验研究

以初二学生为被试 ,考察了不同认知方式学生对不同体裁文章以及对有无标记说明文的学习效果。结果表明,(1)不同认知方式学生对散文的学习无明显差异,对说明文的学习场独立学生要好于场依存者;(2)场独立者对有标记的说明文的学习效果要好于场依存者;对无标记说明文的学习,场独立与场依存者之间不存在明显差异。     

危险类型对公交驾驶员危险知觉的影响

结合反应时方法和多维度驾驶风格量表,以140名公交驾驶员为研究对象,采用2（危险类型：隐藏危险、明显危险）×2（驾驶员分组：有无交通违规/事故记录）的混合实验设计考察危险类型对危险知觉的影响。结果发现：驾驶员对明显危险的反应时比隐藏危险短,无交通违规/事故记录驾驶员对明显和隐藏危险的反应时均比有交通违规/事故记录驾驶员短。控制驾驶风格后,危险类型主效应不再显著。结果表明,公交驾驶员危险知觉的特点随着危险类型不同而变化。     

群体断层激活及负面效应涌现：熙宁变法缘何从志同道合走向四分五裂？

群体断层构念与决定组织变革成败的高管团队多重人际交互及其演进表征十分契合。但群体断层因为什么而激活?激活了的群体断层是如何影响高管团队的群体过程及组织绩效产出?这些问题亟需实证性的探索和检验。本研究基于《王安石年谱长编》,辅以《宋史》及后人相关专题研究,采用质性研究中的扎根理论方法,以王安石越次入对宋神宗到王安石第二次罢相为观察窗口期,对此期间与他存在密切交互关系的52个关键人物的交互过程、交互结果及成因进行了编码分析。结果发现：(1)群体断层激活及负面效应涌现能完美解释熙宁变法的演进过程及最终的失败;(2)关键岗位人员王安石人际交互风格的不同构面是激活熙宁变法中不同群体断层的主要变量;(3)王安石与直接上级宋神宗、本位群体变法新晋和他位群体同朝老臣之间交互的聚散性,决定了活化的群体断层效应正负及交互演进表征,进而决定了熙宁变法的失败。本研究为群体断层激活变量的识别及不同群体断层在同一时空下的叠加效应提供了新的洞见,同时为组织变革及高管团队多样性的管理提供了实证资鉴和理论指导。
