The effect of deferring feedback on rule-based and information-integration category learning. (2025)
Journal Article

Previous work has shown that deferring feedback significantly impairs two-dimensional information-integration category learning, often thought to recruit an implicit learning system, but leaves intact unidimensional rule-based learning, commonly assu...

The effectiveness of alcohol label information for increasing knowledge and awareness: A rapid evidence review (2023)
Journal Article

Background:- Consumers have difficulty understanding alcoholic units and low risk drinking guidelines (LRDG). Labelling may improve comprehension. The aims of this rapid evidence review were to establish the effectiveness of on-bottle labelling for (...

Applying insights on categorisation, communication, and dynamic decision-making: A case study of a 'simple' maritime military decision (2022)
Journal Article

A complete understanding of decision-making in military domains requires gathering insights from several fields of study. To make the task tractable, here we consider a specific example of short-term tactical decisions under uncertainty made by the m...

Journal Article

This article presents a discussion of the importance of power analyses, providing an overview of when power analyses should be run in the context of the field of Human-Robot Interaction, as well as some examples of how to perform a power analysis. Th... Read More about Have I got the power? Analysing and reporting statistical power in HRI.

Neural correlates of the inverse base rate effect (2021)
Journal Article

The inverse base rate effect (IBRE) is a nonrational behavioral phenomenon in predictive learning. Canonically, participants learn that the AB stimulus compound leads to one outcome and that AC leads to another outcome, with AB being presented three...

Absence of cross-modality analogical transfer in perceptual categorization (2020)
Journal Article

Analogical transfer has been previously reported to occur between rule-based, but not information-integration, perceptual category structures (Casale, Roeder, \& Ashby, 2012). The current study investigated whether a similar pattern of results would... Read More about Absence of cross-modality analogical transfer in perceptual categorization.

Goal-directed control in Pavlovian-instrumental transfer (2019)
Journal Article

The current article concerns human outcome-selective Pavlovian-instrumental transfer (PIT), where Pavlovian cues selectively invigorate instrumental responses that predict common rewarding outcomes. Several recent experiments have observed PIT effect... Read More about Goal-directed control in Pavlovian-instrumental transfer.

Dissociable learning processes, associative theory, and testimonial reviews: A comment on Smith and Church (2018) (2019)
Journal Article

Smith and Church (Psychonomic Bulletin \& Review, 25, 1565?1584 2018) present a ?testimonial? review of dissociable learning processes in comparative and cognitive psychology, by which we mean they include only the portion of the available evidence t...

What can you see? Identifying cues on internal states from the movements of natural social interactions (2019)
Journal Article

In recent years, the field of Human-Robot Interaction (HRI) has seen an increasing demand for technologies that can recognize and adapt to human behaviors and internal states (e.g., emotions and intentions). Psychological research suggests that human... Read More about What can you see? Identifying cues on internal states from the movements of natural social interactions.

Spatial referring expressions in child-robot interaction: Let's be ambiguous! (2018)
Presentation / Conference Contribution

Establishing common ground when attempting to disambiguate spatial locations is difficult at the best of times, but is even more challenging between children and robots. Here, we present a study that examined how 94 children (aged 5-8) communicate sp... Read More about Spatial referring expressions in child-robot interaction: Let's be ambiguous!.

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.

The PInSoRo dataset: Supporting the data-driven study of child-child and child-robot social dynamics (2018)
Journal Article

© 2018 Lemaignan et al. The study of the fine-grained social dynamics between children is a methodological challenge, yet a good understanding of how social interaction between children unfolds is important not only to Developmental and Social Psycho...

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...

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.

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)...

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...
