Investigating the mechanistic role of painful self-experience in emotional contagion: an effect of auto-conditioning?

The paper investigates whether auto-conditioning, through auditory associations with pain squeaks, enhances emotional contagion in rodents, but finds no significant differences in fear responses across experimental groups.

Digital embryos - A novel technical approach to investigate perceptual categorization in pigeons (Columba livia) using machine learning

This paper uses digital embryos and machine learning to study how pigeons categorize stimuli, finding that pecking patterns correlate with stimulus features and that pigeons use multiple categorization strategies.

Emergence of complex dynamics of choice due to repeated exposures to extinction learning

This study examines how repeated extinction learning sessions affect behavior in pigeons, revealing session-specific variability and a decay in renewal effects over time.
