This neuroscience study investigated why time sometimes feels longer than it really is. By replacing simple geometric shapes with animal images, the researcher tested whether arousal or novelty drives temporal dilation. Results supported the oddball effect, showing that stimulus change, rather than emotional significance, was the primary factor influencing perceived duration.

This research examines whether anhedonia—a core symptom of depression marked by reduced pleasure and motivation—is linked to impairments in working and episodic memory. While memory performance did not differ across anhedonia levels, the findings highlight the need for further study to develop targeted, memory-based interventions.
