Using a robot peer to encourage the production of spatial concepts in a second language (2018)
Presentation / Conference Contribution

We conducted a study with 25 children to investigate the effectiveness of a robot measuring and encouraging production of spatial concepts in a second language compared to a human experimenter. Productive vocabulary is often not measured in second la... Read More about Using a robot peer to encourage the production of spatial concepts in a second language.

Due process in dual process: Model-recovery simulations of decision-bound strategy analysis in category learning (2018)
Journal Article

Behavioral evidence for the COVIS dual-process model of category learning has been widely reported in over a hundred publications (Ashby \& Valentin, 2016). It is generally accepted that the validity of such evidence depends on the accurate identific...

Initial training with difficult items does not facilitate category learning (2018)
Journal Article

In the phenomenon of transfer along a continuum (TAC), initial training on easy items facilitates later learning of a harder discrimination. TAC is a widely replicated cross-species phenomenon that is well predicted by certain kinds of associative th...

Due process in dual process: A model-recovery analysis of Smith et al. (2014) (2017)
Presentation / Conference Contribution

Considerable behavioral evidence has been cited in support of the COVIS dual-system model of category learning (Ashby \& Valentin, 2016). The validity of the inferences drawn from these data critically depend on the accurate identification of partici...

Progress in modeling through distributed collaboration: concepts, tools and category-learning examples (2017)
Book Chapter

Formal modeling in psychology is failing to live up to its potential due to a lack of effective collaboration. As a first step towards solving this problem, we have produced a set of freely available tools for distributed collaboration. This article...

Modelling category learning using a dual-system approach: A simulation of Shepard, Hovland and Jenkins (1961) by COVIS (2016)
Presentation / Conference Contribution

This paper examines the ability of a dual-system, formal model of categorization COVIS (Ashby, Paul \& Maddox, 2011) to predict the learning performance of participants on the six category structures described in Shepard, Hovland and Jenkin?s (1961)...

Memory for exemplars in category learning (2016)
Presentation / Conference Contribution

Some argue that category learning is mediated by two competing learning systems: one explicit, one implicit (Ashby et al., 1998). These systems are hypothesised to be responsible for learning rule-based and information-integration category structures... Read More about Memory for exemplars in category learning.

Feedback can be superior to observational training for both rule-based and information-integration category structures (2015)
Journal Article

The effects of two different types of training on rule-based and information-integration category learning were investigated in two experiments. In observational training, a category label is presented, followed by an example of that category and the...
