    Kitten exploration and locomotion change significantly between 3 and 7 weeks of age. These age-dependent behavioral shifts suggest a role for hippocampal maturation in early development.

    Area of Science:

    • Developmental psychology
    • Animal behavior
    • Neuroscience

    Background:

    • Kitten exploratory behavior undergoes significant development during the first few weeks of life.
    • Understanding age-related changes in motor activity and spatial exploration is crucial for developmental studies.

    Purpose of the Study:

    • To investigate age-dependent changes in open-field behavior in kittens aged 3 to 7 weeks.
    • To identify specific behavioral shifts related to locomotion and exploration with increasing age.

    Main Methods:

    • Seventy-eight kittens aged 3 to 7 weeks were observed in an open-field arena.
    • Behavioral metrics including squares entered, backtracking, and locomotion decrements were recorded and analyzed.

    Main Results:

    Related Experiment Videos

    • Exploratory activity (squares entered) peaked in 5- and 6-week-old kittens.
    • The tendency to backtrack decreased with age, with a notable change between 4 and 5 weeks.
    • Locomotion showed a within-session decrement that varied with age, being largest in 3-week-olds and smallest in 4-week-olds.

    Conclusions:

    • Kitten behavior in an open-field arena exhibits distinct age-dependent patterns.
    • The observed changes in exploration and locomotion suggest a role for hippocampal maturation in early development.
