Adaptive judgmental processes

理论和实验工作计划在心理物理学、判断和决策的广泛领域中的一些不同的问题上进行。主要目的是确定与感知的、数字的和记住的备选方案进行比较判断的基本属性。这一长期研究计划的一个持续重点是进一步开发量化模型，允许显式表达响应时间、响应精度和置信度。通过计算机模拟和正式的数学发展，这些模型正在扩展到多个选择的情况，还有一系列关于两个、三个和四个刺激选择的实验。然后，我们将在持续的实验工作中对这些模型进行实证检验，实验工作的重点是确定比较实验中使用的指令如何与要比较的刺激的性质相互作用(语义一致性效应)，我们如何感知简单的感觉事件和我们如何记忆它们之间的关系(记忆心理物理学)，数字和符号心理表征中的空间成分(SNARC效应)，以及我们如何对我们的决定和判断的正确性产生信心，以及我们的信心表达与我们表现的实际准确性之间的密切关系(信心的校准)。

Theoretical and experimental work is planned on a number of different problems in the broad areas of psychophysics, judgement, and decision-making. The primary aim is to determine the fundamental properties of comparative judgments with perceived, numerical, and remembered alternatives. A continuing focus of this long-term research programme is the further development of quantitative models that permit explicit expressions for response times, response accuracy, and confidence. Extensions of these models, both through computer simulation and formal mathematical development, to the multi-alternative case are underway, as are a series of experiments with two, three and four stimulus alternatives. These models will then be empirically examined in the context of continuing experimental work which focuses on the determining how the instructions used in comparison experiments interact with properties of the stimuli to be compared (the semantic congruity effect), the relationships between how we perceive simple sensory events and how we remember them (memory psychophysics), the spatial components in the mental representations of numbers and symbols (SNARC effect), and how we arrive at a feeling of the confidence in the correctness of our decisions and judgements and how closely our expression of confidence relates to actual accuracy of our performance (the calibration of confidence).
