Play behavior of blinded and sighted juvenile rats was measured using the brief paired-encounter procedure. Dyads of sighted-sighted, blind-blind, or sighted-blind rats were observed in a large or small chamber on alternate days for ages 28 through 43 days. Blinded rats played as frequently as sighted rats regardless of pair composition or chamber size. Vision is not essential for initiating or maintaining play fighting.
使用简短配对相遇程序测量失明和有视力的幼年大鼠的玩耍行为。在28至43日龄时，每隔一天在大或小的实验室内观察有视力-有视力、失明-失明或有视力-失明的大鼠二元组。无论配对组合或实验室内大小如何，失明大鼠与有视力大鼠玩耍的频率相同。视力对于发起或维持玩耍打斗并非必不可少。
