Asian elephants' ears, measuring about 1.6 feet (0.5 m) long, make up only about 8% of their body length. 84, 10851093 (2012). We then compared the full model (AIC 913.19, logLik 445.60) to a null model with only the random effects (AIC 1064.58, logLik 529.29), yielding a statistically significant difference (2(8) 167.39, p < .001). When you have a hearing loss, your hearing range changes. The asymmetry between compliance and rejection is reflected in the formal design of these moves: while the vast majority of rejections are verbalized, most complying responses, in most cultures, are produced without words.
