چکیده

It has been repeatedly debated which strategies people rely on in inference. These debates have been difficult to resolve, partially because hypotheses about the decision processes assumed by these strategies have typically been formulated qualitatively, making it hard to test precise quantitative predictions about response times and other behavioral data. One way to increase the precision of strategies is to implement them in cognitive architectures such as ACT-R. Often, however, a given strategy can be implemented in several ways, with each implementation yielding different behavioral predictions. We present and report a study with an experimental paradigm that can help to identify the correct implementations of classic compensatory and noncompensatory strategies such as the take-the-best and tallying heuristics, and the weighted-linear model.

Cognitive and Probabilistic Models of Group Decision Making

We introduce an experiment designed to study trade-offs in collaborative decision making environments such as finding the best level of selectivity and abstraction in sharing information, and their impact on the time course and accuracy of group decisions. Two models of the experiment are presented: a cognitive model using the ACT-R cognitive architecture and a probabilistic argumentation model...

Investigating the missing data effect on credit scoring rule based models: The case of an Iranian bank

Credit risk management is a process in which banks estimate probability of default (PD) for each loan applicant. Data sets of previous loan applicants are built by gathering their data, and these internal data sets are usually completed using external credit bureau’s data and finally used for estimating PD in banks. There is also a continuous interest for bank to use rule based classifiers to b...

Constraining Bayesian Inference with Cognitive Architectures: An Updated Associative Learning Mechanism in ACT-R

Bayesian inference has been shown to be an efficient mechanism for describing models of learning; however, concerns over a lack of constraint in Bayesian models (e.g., Jones & Love, 2011) has limited their influence as being a description of the ‘real’ processes of human cognition. In this paper, we review some of these concerns and argue that cognitive architectures can address these concerns ...

Remember–know models as decision strategies in two experimental paradigms

In the remember–know paradigm, subjects report the subjective basis for their ‘‘old’’ response to a memory probe to be either recollection of specific details (‘‘remembering’’) or familiarity (‘‘knowing’’). The response rates for these judgments are often taken as direct measures of underlying processes, but this process-pure account is implausible in view of the known effects of experimental p...

Convergence and Constraints 1 Running Head: CONVERGENCE AND CONSTRAINTS Convergence and Constraints Revealed in a Qualitative Model Comparison

We contrasted and compared independently developed computational models of human performance in a common dynamic decision-making task. The task, called Dynamic Stocks and Flows, is simple and tractable enough for laboratory experiments yet exhibits many characteristics of macrocognition. A macrocognitive model was developed using a computational instantiation of Recognition-Primed Decision-Maki...
