A psychological mechanism for the development of anxiety (2024)
Journal Article

Although numerous behavioural constructs have been proposed to account for anxiety disorders, how these develop within an individual has been difficult to predict. In this perspective, I selectively review clinical and experimental evidence suggestin... Read More about A psychological mechanism for the development of anxiety.

Renewal of instrumental avoidance in humans (2024)
Journal Article

The ABA renewal effect occurs when behaviour is trained in one context (A), extinguished in a second context (B), and test occurs in the training context (A). Two mechanisms that explain ABA renewal are context summation at test and contextual modula... Read More about Renewal of instrumental avoidance in humans.

The impact of emotional valence on generalization gradients (2024)
Journal Article

Generalization enables individuals to respond to novel stimuli based on previous experiences. The degree to which organisms respond is determined by their physical resemblance to the original conditioned stimulus (CS+), with a stronger response elici...

The effects of goal–landmark distance on overshadowing: A replication in humans (Homo sapiens) of Goodyear and Kamil (2004). (2023)
Journal Article

Goodyear and Kamil (2004) assessed the ability of Clark’s nutcrackers to find buried food based on a cross-shaped array of landmarks at different distances from the goal. Their findings suggested that proximal landmarks overshadowed learning about di...

Further evidence for the role of temporal contiguity as a determinant of overshadowing (2023)
Journal Article

Three experiments explored whether weakening temporal contiguity between auditory cues and an aversive outcome attenuated cue competition in an avoidance learning task with human participants. Overall, with strong temporal contiguity between auditory... Read More about Further evidence for the role of temporal contiguity as a determinant of overshadowing.

Category relevance attenuates overshadowing in human predictive learning. (2023)
Journal Article

In situations in which multiple predictors anticipate the presence or absence of an outcome, cues compete to anticipate the outcome, resulting in a loss of associative strength compared to control conditions without additional cues. Critically, there... Read More about Category relevance attenuates overshadowing in human predictive learning..

Genetic and environmental influences on one-trial conditioned context aversion in mice (2023)
Journal Article

Anticipatory nausea (AN) is caused by an association between contextual cues and the experience of nausea (the side effects of chemotherapy or radiation treatment) and it develops predominantly in female patients undergoing chemotherapy. Preclinical... Read More about Genetic and environmental influences on one-trial conditioned context aversion in mice.

Conditioned place avoidance in the planaria Schmidtea mediterranea: A pre-clinical invertebrate model of anxiety-related disorders (2023)
Journal Article

The objective of the present study was to develop a model of avoidance learning and its extinction in planarians (Schmidtea mediterranea). Based on previous experiments showing conditioned place preference, we developed a procedure to investigate con...

Contiguity and overshadowing interactions in the rapid-streaming procedure (2023)
Journal Article

When multiple cues are associated with the same outcome, organisms tend to select between the cues, with one revealing greater behavioral control at the expense of the others (i.e., cue competition). However, non-human and human studies have not alwa... Read More about Contiguity and overshadowing interactions in the rapid-streaming procedure.

Social overshadowing: Revisiting cue-competition in social interactions (2023)
Journal Article

In a large variety of contexts, it is essential to use the available information to extract patterns and behave accordingly. When it comes to social interactions for instance, the information gathered about interaction partners across multiple encoun...

Temporal contiguity determines overshadowing and potentiation of human Action-Outcome performance (2022)
Journal Article

Three experiments (n = 81, n = 81, n = 82, respectively) explored how temporal contiguity influences Action-Outcome learning, assessing whether an intervening signal competed, facilitated, or had no effect on performance and causal attribution in und... Read More about Temporal contiguity determines overshadowing and potentiation of human Action-Outcome performance.

Signal detection analysis of contingency assessment: Associative interference and nonreinforcement impact cue-outcome contingency sensitivity, whereas cue density affects bias (2022)
Journal Article

In a signal detection theory approach to associative learning, the perceived (i.e., subjective) contingency between a cue and an outcome is a random variable drawn from a Gaussian distribution. At the end of the sequence, participants report a positi... Read More about Signal detection analysis of contingency assessment: Associative interference and nonreinforcement impact cue-outcome contingency sensitivity, whereas cue density affects bias.

Temporal and Spatial Contiguity Are Necessary for Competition Between Events (2022)
Journal Article

Over the last 50 years, cue competition phenomena have shaped theoretical developments in animal and human learning. However, recent failures to observe competition effects in standard conditioning procedures, as well as the lengthy and ongoing debat...

Fear memory modulation by incentive down and up-shifts (2022)
Journal Article

Research on retrieval-induced malleability of maladaptive emotional memories has been mostly focused on the effect of drugs and extinction (i.e. post-retrieval extinction). Only a few studies addressed post-retrieval appetitive-aversive interactions.... Read More about Fear memory modulation by incentive down and up-shifts.
