Area of Science:

Cognitive Science
Animal Behavior
Comparative Psychology

Background:

Causal reasoning relies on tracking object identity and trajectory.
Previous research has not demonstrated simultaneous representation of these factors in non-human animals.

Purpose of the Study:

To investigate if kea can represent out-of-sight object trajectories and identities simultaneously.
To explore kea's capacity for mental simulation in complex hidden object tasks.

Main Methods:

Kea were presented with three tasks involving tracking or predicting hand movements behind a screen.
The tasks assessed the birds' ability to infer hidden object properties.

Main Results:

Kea demonstrated the ability to track and predict hidden hand trajectories.
The results indicate successful representation of both identity and trajectory of hidden objects.

Conclusions:

Kea possess the cognitive capacity for mental simulation.
This suggests advanced reasoning abilities in kea concerning hidden moving objects.
