Ambiguous relationships between events may be established using interference procedures such as latent inhibition, extinction, or counterconditioning. Under these conditions, the retrieval of individual associations between a stimulus and outcome is...

Acute itch induces attentional avoidance of itch-related information (2022)
Journal Article

Attention is known to modulate itch intensity. In contrast, the reverse relationship, i.e. the degree to which the presence of an acute itch affects attention, is currently not well understood. The aims of this study were to investigate whether acute... Read More about Acute itch induces attentional avoidance of itch-related information.

Domestic dogs (Canis lupus familiaris) are sensitive to the correlation between pitch and timbre in human speech (2021)
Journal Article
