Study links orangutans' food choices to sounds of peers laughing
Research reported by the Guardian suggests social sounds may influence learning, though the extract provides no study methods or effect sizes.
The Guardian reports a study in which captive orangutans were more likely to choose treats associated with sounds of their peers laughing. Researchers interpret the result as suggesting that emotions influence learning.
What holds up
- ✓The report identifies captive orangutans as the study subjects and food choice as the observed behaviour.
- ✓The reported preference concerns treats associated with laughter, rather than a demonstrated general increase in learning ability.
What doesn't yet
- ?The extract provides no sample size, control conditions, effect size or replication evidence.
- ?The interpretation that emotions influence learning goes beyond the directly reported food-choice observation.
Ask before you share
- →How did researchers control for familiarity or other features of the sounds?
- →How many animals were tested, and does the result extend beyond captive subjects?
