Overview

Registered report demonstrates positive affect from playful handling in laboratory rats, indicating notable sex differences in responses.

Key Points

  • Tickling promotes positive affect in laboratory rats, measured by ultrasonic vocalisations (USVs).
  • Juvenile male and female Wistar rats given playful handling show increased USVs compared to controls.
  • Females vocalised more with minimal pinning, showing preference for less restraint during tickling.
  • Findings highlight sex differences, suggesting females may find tickling more rewarding than males.
