Tracing template Investigating representation perceptual

项目摘要

Adaptive perception requires the prioritization of relevant over irrelevant information. When we are looking for a specific book of which we only remember the color of its cover, we can limit our search to mainly that color. The mental representation of what we are looking for is called the attentional template (also target template, search template, attentional set; e.g., Folk et al., 1992). An attentional template is a flexible representation reflecting current selection preferences, as derived from continuously changing task demands and prior selection history. Even though attentional templates are essential for shaping and controlling perception and action in everyday life, surprisingly little is known about their nature. For example, when you look for your car keys, do you look for their shape, their color, or both? In case of the latter, are shape and color integrated in a single representation, or are they independently represented? Can you look for your wallet at the same time, without affecting your "key" template? Furthermore, it is often assumed that visual attention is guided by visual templates, but it is perfectly possible that non-visual types of representation (e.g., semantic codes) are also involved. Finally, the nature of the template may change fundamentally in the course of learning, as a result of selection history. The aim of this collaborative project is to answer some of these fundamental questions.

适应性感知要求相关信息优先于不相关信息。当我们寻找一本特定的书，而我们只记得它的封面颜色时，我们可以将搜索范围限制在主要的颜色上。我们正在寻找的东西的心理表征被称为注意力模板（也称为目标模板，搜索模板，注意力集;例如，Folk等人，1992年）。注意模板是反映当前选择偏好的灵活表示，如从不断变化的任务需求和先前选择历史中得到的。尽管注意力模板对于塑造和控制日常生活中的感知和行动至关重要，但令人惊讶的是，人们对它们的性质知之甚少。例如，当你寻找你的车钥匙时，你是看它们的形状，颜色，还是两者兼而有之？在后者的情况下，形状和颜色是整合在一个单一的表示，还是他们独立表示？你能同时寻找你的钱包，而不影响你的“钥匙”模板吗？此外，通常假设视觉注意力由视觉模板引导，但是完全可能的是，非视觉类型的表示（例如，语义代码）也被涉及。最后，由于选择历史，模板的性质可能在学习过程中发生根本变化。这个合作项目的目的是回答其中一些基本问题。
