项目摘要
Dynamic-stochastic models, based on the notion of sequential sampling, are commonly used to predict choice behavior and response times in many areas of psychology, from basic perceptual tasks to multidimensional preference and decision making. Typically, these models can only account for binary decisions and unidimensional stimuli. However, many applications require an extension of the sequential sampling mechanism to multi-attribute choice options with multiple alternatives. Formal derivation of model predictions for more complex situations is often difficult or impossible, severely limiting the psychological interpretability and experimental tests of these models. An exception is Multiattribute Decision Field Theory (MDFT), developed in Diederich (1997), and its extension, the multi-stage model (Diederich & Oswald, 2014), which is based on a matrix approximation of continuous processes.The goal of this project is to advance the sequential sampling approach within the class of dynamic-stochastic decision models. To this end, we (1) extend the multi-stage model to include a variety of mechanisms for attribute handling (fixed and random processing order, switching times, and process durations) that constitute different hypotheses about the distribution of attention in stimulus processing. Then follows (2) the development of a mechanisms that also accounts for non-responses (e.g. missed deadline). For that, different functions of decision criteria are considered (i.e. absorbing boundaries of the stochastic process). Analytical solutions for all models will be strived for.The empirical part of this project will experimentally probe the multi-stage model. We will explore different aspects of attribute processing in discrimination and choice paradigms. The first series of experiments will test hypotheses about the effect of payoffs, considered as stimulus attribute, on response frequencies in two different perceptual discrimination tasks. The effect of temporal distribution of information on task performance will be studied in a second series of experiments. Finally, the effect of the number of attributes on preference under risk will be investigated in a third experimental series.
基于序贯抽样概念的动态随机模型通常用于预测心理学许多领域的选择行为和反应时间,从基本的感知任务到多维偏好和决策。通常,这些模型只能解释二元决策和一维刺激。然而,许多应用程序需要扩展的顺序抽样机制,多属性选择选项与多个替代品。对于更复杂的情况,模型预测的正式推导通常是困难的或不可能的,严重限制了这些模型的心理可解释性和实验测试。一个例外是多属性决策场理论(MDFT),在Diederich(1997)中发展,及其扩展,多阶段模型(Diederich & Oswald,2014),它基于连续过程的矩阵近似。本项目的目标是在动态随机决策模型类中推进序贯抽样方法。为此,我们(1)扩展了多阶段模型,以包括各种属性处理机制(固定和随机处理顺序,切换时间和处理持续时间),这些机制构成了关于刺激处理中注意力分布的不同假设。然后是(2)制定一种机制,也对不答复(如错过最后期限)作出解释。 为此,考虑了决策准则的不同功能(即随机过程的吸收边界)。本计画的实证部分将针对多阶段模式进行实验探索。我们将探讨不同方面的属性处理的歧视和选择范式。第一组实验将检验两种不同知觉辨别任务中作为刺激属性的报酬对反应频率的影响。信息的时间分布对任务绩效的影响将在第二系列实验中进行研究。最后,将在第三个实验系列中研究属性数量对风险偏好的影响。
