非目标工作记忆表征下颜色关联和抽象关联的注意捕获和抑制

采用工作记忆—视觉搜索双任务范式,探讨在非目标工作记忆表征下,颜色关联和抽象关联干扰子的注意捕获和抑制现象。实验一结果发现,颜色关联干扰子在快速反应阶段捕获注意,随后被成功抑制;抽象关联干扰子仍能捕获注意。实验二消除知觉凸显后,结果发现颜色关联条件的抑制消失,干扰子重新捕获注意。结果表明,有效抑制策略受不同关联干扰子加工先后顺序的影响,选择性抑制颜色关联干扰子,而颜色特征的凸显有助于抑制策略形成。     

作文前计划的时间因素对前计划效应的影响

采用自然实验与实验室实验相结合的方法,通过两个实验探讨作文前计划的时间因素对前计划效应的影响。结果发现,作文方式决定前计划用时,前计划用时影响前计划效应,前计划效应决定前计划形式的作用。这一结果表明,在既有前计划又有外部视觉表征的情况下,前计划本身在前计划时限与前计划形式的关系中起着决定性的作用。因为前计划的存在,使外部视觉表征的作用呈现出更为复杂的情况,从而表现为长时限前计划即充分前计划条件下,外部视觉表征具有重要意义,短时限前计划即不充分前计划条件下,计划比外部视觉表征更具价值。     

Making Things Happen

We explore some logics of change, focusing on commands to change the world in such a way that certain elementary propositions become true or false. This investigation starts out from the following two simplifying assumptions: (1) the world is a collection of facts (Wittgenstein), and (2), the world can be changed by changing elementary facts (Marx). These assumptions allow us to study the logic of imperatives in the simplest possible setting.     

The Use and Evolution of Stories as a Mode of Problem Representation: Soviet and French Military Officers Face the Loss of Empire

Experimental work on modes of problem representation (Sylvan, Diascro, & Haddad, 1996) has found that the story model of Pennington and Hastie (1986, 1988) is a helpful construct in understanding how people reach decisions when dealing with questions of foreign policy. Here, a modified version of the story model is applied to statements by military officers in the Soviet Union and in France, representing the situations they face before and after the loss of Eastern Europe and Indochina, respectively (Charlick-Paley, 1997). Both baseline stories and those after the losses of empire are examined to test the hypothesis that when a military experiences the loss of its state's empire, officers will formulate a new story that justifies the change in its status, and that this new story will motivate new patterns of civil-military relations in the post-imperial era. The hypothesis finds general support, and stories are found to be a useful vehicle in understanding differences between groups of military officers. An analysis of how officers' stories change over time yields intriguing results as to how mutable stories are and which elements of a story are most likely to change first. In particular, expansion of the level of a goal is found to be a representational response to the political stimulus of loss of empire.     

Domestic hens have declarative representations

It is generally considered that information can be stored either as a procedural or as a declarative representation. A devaluation technique was used to determine whether hens have declarative representations. Individual hens (Gallus gallus domesticus) were fed in an enclosure with two containers, each with a new food type. One of the food types was devalued by pre-feeding with that food, after which the hens were tested with empty food containers. The pre-feeding should only affect the choice of the hens if they have learned where a particular food type was (declarative representation) rather than “go left when coming into the enclosure” (procedural representation). A significant proportion of the hens went to the location previously occupied by the non-devalued food (seven out of eight). This supports the hypothesis that domestic hens can form declarative representations. Received: 6 March 1999 / Accepted after revision: 1 November 2000
