The glm() function was used with a Poisson error distribution. Model 1: TEA-1 ∼ Home Speakers/New Speakers, Poisson error dist. Model 2: TEA-2 ∼ Home Speakers/New Speakers, Poisson error dist. Model 3: TEA-3 ∼ Home Speakers/New Speakers, Poisson error dist. Model 4: Backward digit span ∼ Home Speakers/New Speakers, Poisson error dist.
