FOK研究中一种新的标准测验——过度重复学习

提出FOK研究中一种新的标准测验形式——过度重复学习,并验证过度重复学习作为FOK研究的标准测验的可行性;另外还比较了作为标准测验,过度重复学习与再认的差别。同时,还探索了FOK判断中存在的两种错误类型——替代性错误和忽略性错误在FOK判断等级和标准测验成绩方面的差异。两个实验结果表明：FOK判断在预期随后的标准测验(过度重复学习和再认)成绩上是有准确性的;过度重复学习可以作为一种标准测验。实验结果还显示：替代性错误比忽略性错误的FOK判断等级要高;且无论是用再认还是用过度重复学习做标准测验,都能检验出两种错误类型项目在记忆激活强度上的差异。     

The Psychodynamics of Australian Settler–Nationalism: Assimilating or Reconciling With the Aborigines?

Settler–nationalism is a form of nationalism that must face specific cultural dilemmas as a result of the dispossession of indigenous peoples. Since the Second World War, Australia has attempted to come to terms with its past of dispossession and to find ways to incorporate Aborigines within national imaginings, and within the nation itself. This paper argues that there are two modes of settler–nationalism—termed assimilationist and indigenizing—that compete to organize the national reality, including relations between the settler and indigenous populations. Kleinian object relations theory is drawn upon to delineate the emotional structures of the two modes of nationalism. Implications for indigenous rights, in particular for Aboriginal land rights, are examined.     

From Fragments to Geometric Shape: Changes in Visual Object Recognition Between 18 and 24 Months

ABSTRACT— Visual object recognition is foundational to processes of categorization, tool use, and real-world problem solving. Despite considerable effort across many disciplines and many specific advances, there is no comprehensive or well-accepted account of this ability. Moreover, none of the extant approaches consider how human object recognition develops. New evidence indicates a period of rapid change in toddlers' visual object recognition between 18 and 24 months that is related to the learning of object names and to goal-directed action. Children appear to shift from recognition based on piecemeal fragments to recognition based on geometric representations of three-dimensional shape. These findings may lead to a more unified understanding of the processes that make human object recognition as impressive as it is.     

客体复杂度影响工作记忆可存储的客体数目

采用变化觉察范式,以对侧延迟活动（contralateral delay activity,CDA）的幅值为指标,通过操纵记忆刺激的复杂程度,对视觉工作记忆中可存储的客体数目（即工作记忆容量）问题进行了探讨。结果表明,2个复杂客体条件下的CDA幅值与4个复杂客体条件无显著差异,而4个简单客体条件的CDA幅值显著高于2个简单客体条件,即CDA的幅值受客体复杂度的调节。基于该结果推论：并非视觉工作记忆总能存储4个客体,其可存储的客体数目受客体复杂度影响。     

The Hospital Room as Uncanny: Psychoanalytic Observations and Recommendations for Pastors and Chaplains

This essay in applied psychoanalysis is written for the field of pastoral psychology, and it also has obvious affinities with the medical humanities. The author uses Freud’s (The uncanny. In J. Strachey (Ed. and Trans.), The standard edition of the complete psychological works of Sigmund Freud (Vol. 17, pp. 217–256). Vintage, London, 1919/2001) “The Uncanny” to question the concept of homelike hospital rooms. Instead of making patients feel more comfortable, the authors believes that these rooms could, in some cases, actually increase the anxiety of patients. The author uses Helena Michie’s personal story of her experience of touring a birthing suite to support this argument, as well as some poetry by Billy Collins. The author, however, does not stop with identifying a problem, as he also suggests that pastors and chaplains, when they provide care for their patients, should help them identify and use their own transitional and transformational objects. These objects, of course, will be highly idiosyncratic, and it is precisely this kind of attention—attention to the idiosyncrasies of individuals—that pastors and chaplains should be giving to those in their care. While there is a growing literature on D. W. Winnicott, who coined the term “transitional object,” and Christopher Bollas, who gave us the term “transformational object,” in medical and pastoral circles, the author suggests that attention to and the endorsement of the use of transitional and transformational objects should become a part of hospital policy, if only in chaplaincy handbooks, so as to recognize what many individuals are already doing.     

Lateralized effects of categorical and coordinate spatial processing of component parts on the recognition of 3D non-nameable objects

Participants performed two object-matching tasks for novel, non-nameable objects consisting of geons. For each original stimulus, two transformations were applied to create comparison stimuli. In the categorical transformation, a geon connected to geon A was moved to geon B. In the coordinate transformation, a geon connected to geon A was moved to a different position on geon A. The Categorical task consisted of the original and the categorically transformed objects. The Coordinate task consisted of the original and the coordinately transformed objects. The original object was presented to the central visual field, followed by a comparison object presented to the right or left visual half-fields (RVF and LVF). The results showed an RVF advantage for the Categorical task and an LVF advantage for the Coordinate task. The possibility that categorical and coordinate spatial processing subsystems would be basic computational elements for between- and within-category object recognition was discussed.     

多目标追踪任务中不同运动方式非目标的抑制机制

采用多目标追踪范式结合点探测技术的方法, 考察视觉系统对不同运动方式(静止和规则运动)非目标的抑制机制。实验一将部分非目标设置为静止, 考察静止非目标的抑制机制; 实验二将部分非目标设置为规则运动, 以提高任务难度, 考察规则运动非目标的抑制机制。结果发现: (1) 实验一中静止非目标受到抑制, 抑制量与运动非目标没有差异; (2) 实验二中规则运动非目标受到抑制, 抑制量显著小于随机运动非目标; (3)综合两实验发现, 随着任务难度的提高, 只有随机运动非目标的抑制量显著增加, 而静止非目标与规则运动非目标的抑制量差异不显著。最后, 就视觉系统对不同运动方式非目标的抑制机制进行了讨论。     

选择、自我表达与选择扩散效应

自我表达会影响西方人的态度, 产生选择扩散效应。国外相关的跨文化研究发现东方人不存在该效应。通过4个实验研究中国文化下自我表达对选择态度的影响, 发现选择方式(主动、被动)和自我表达形式(直接、间接)对选择态度产生影响。无论是自己的主动选择还是强加的被动选择, 直接的自我表达会增加对所获对象的喜爱程度, 表现为对获得性的肯定。研究者认为, 两种选择方式下不同的心理加工过程导致了这种获得性：直接表达使个人态度暴露在外, 进行主动选择时要对他人的给予做出肯定回应; 而进行被动选择时, 人们要减缓因利益受损可能导致的失调, 同时中国文化下的面子策略也使人们增加对所获对象的喜爱程度。不过, 间接的自我表达对选择态度的影响不明显。研究者认为, 多个影响因素的相互消长使选择态度得以维持。     

语境与颜色诊断性对句子理解中物体隐含颜色知觉模拟的影响

具身认知理论的代表知觉符号系统认为知识表征具有知觉特点,并假设语言理解中对于所涉及概念及其隐含属性会即时进行知觉模拟。当前研究采用句图匹配范式,通过三个实验探讨句子理解中是否会对物体隐含颜色属性进行知觉模拟及其具体条件。实验1沿用经典范式验证语言理解中对物体隐含颜色存在知觉模拟过程。实验2通过变化句子前语境考察语境是否支持对于物体隐含颜色知觉模拟的影响。实验3进一步考察当颜色属性与其对应物体存在稳定关联时(即具有高颜色诊断性的物体),在不同语境作用下是否会引起知觉表征的变化。研究结果表明,语言理解中知觉模拟过程是灵活的,语境改变会引起读者所激活的物体颜色知觉表征发生变化,并且对于高颜色诊断物体,即使缺乏支持语境,读者仍然会对句中隐含的物体特定颜色进行知觉模拟。     

贝叶斯推理的三重加工心智模型

自二十世纪60年代Edwards首次用实验研究人类推理是否遵循贝叶斯规则以来,国内外贝叶斯推理研究取得了长足的发展,但也出现了一些困境:对影响贝叶斯推理的客体因素和主体因素研究未成体系,解释理论莫衷一是。未来的研究应该重新审视客体与主体的关系,系统整合和多角度分析影响贝叶斯推理的因素,尝试以三重加工心智模型解释人类贝叶斯推理行为,并对以往的解释理论进行融合,从而更好地揭示人类不确定性决策的本质。
