Mere exposure to telereceptive cues facilitates intake of a novel flavor in chickens (Gallus domesticus).
This experiment investigated whether mere exposure to visual cues of a distinctively colored solution (water) would facilitate intake of a novel flavor (vinegar) of the same distinctive color. Eighty-four chicks received access to clear water, clear vinegar, red water, or red vinegar under conditions which permitted drinking or they received access to clear water or red water under conditions (mere exposure) which prevented drinking. All chicks were then tested on intake of red vinegar. Chicks which had received mere exposure or ingestional experience with red-colored water drank reliably more red vinegar than did chicks which had received prior ingestional experience with the novel taste, vinegar, but not with the visual cues of red. However, intake of red vinegar was reliably greater following ingestional experience with red water than following visual exposure without ingestion. Results supported the mere exposure hypothesis.
