Adaptive judgmental processes

理论和实验工作计划在心理物理学、判断和决策等广泛领域的许多不同问题上进行。主要目的是确定比较判断与感知，数字和记忆的选择的基本性质。这一长期研究计划的持续重点是进一步发展定量模型，使其能够明确表达反应时间、反应准确性和信心。通过计算机模拟和正式的数学发展，将这些模型扩展到多选择的情况，以及一系列有两个、三个和四个刺激选择的实验。然后，这些模型将在持续的实验工作的背景下进行实证检验，这些实验工作的重点是确定比较实验中使用的指令如何与被比较刺激的特性相互作用（语义一致性效应），我们如何感知简单感官事件与我们如何记住它们之间的关系（记忆心理物理学），数字和符号的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，以及我们对信心的表达与我们实际表现的准确性有多密切（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).
