Abstract: | This thesis examines the influence of morphological and identity priming to understand how repetition influences word recognition and novel word learning in first (L1) and second (L2) language adults. The following questions are addressed: How does morphological relatedness between repeated words influence (i) word recognition in natural reading and (ii) novel word learning? (iii) What interactions exist between word repetition and selective attention in novel word learning? Chapter 2 addresses question (i), finding little evidence of morphological priming effects (i.e., faster recognition of a word following a morphologically related word) in L2 reading, and none in L1. The effects of identity priming were ubiquitous in both groups. Chapter 3 examines question (ii) for L1 readers. Low-frequency base words (e.g., caltrop) and novel complex forms (e.g., caltroper) of those bases were primed by two repetitions of identical forms or alternate forms. Learning performance was consistently as good or better after identity priming than after morphological priming. However, orthographic and semantic learning for base forms was stronger in the morphological priming condition. Chapter 4 examines question (iii). Attention was manipulated by delivering attention-inducing instructions, while the control group received no instructions. Exposure was manipulated by embedding novel words either 2, 4, or 8 times. The presence of instruction led to a short-lived speed-up in eye-movements and faster recognition of novel words. Critically, L1 learners reached optimal performance in the post-tests earlier (after 4 exposures), while L2 learners’ performance continued to improve through more exposures. Overall, this thesis shows that morphological priming facilitated L2 visual word recognition and L1 novel word learning when a complex form is a prime, and the base form is a target. We discuss reasons for this asymmetric effect and these results in the framework of the theories of word learning and morphological processing. |
