Production errors made by second language (L2) learners of English have been attributed to markedness, L1 transfer or input frequency (cf. Major, 2001;Edwards & Zampini, 2008; Baptista, Rauber, & Watkins, 2009). This thesis examines the production of 17 English initial consonant clusters (e.g., /pr/ in pray) in a markedness relationship, whereby clusters with greater sonority distance between the first and second consonants are unmarked and clusters with smaller sonority distance between the first and second consonants are marked, by two groups of Saudi Arabian L2 English learners. It also explores the effect of input frequency and L1 transfer. Participants were asked to read 60 sentences and their reading was recorded for acoustic analysis. Analysis showed that prothesis was always used to simplify the clusters, and that, the duration of the prothetic vowel tended to get longer when clusters become more marked. Intermediate participants had greater degree of difficulty in producing the clusters and tended to insert a longer prothetic vowel in general. Markedness explained the performance on #sC clusters; however, performance on non #sC clusters was best explained by L1 transfer.Results further indicated that input frequency was irrelevant to this study. Within the realm of second language (L2) phonology, the acquisition of consonant clusters seems to pose great difficulty for speakers with first languages (L1) that do not allow consonant clusters. It is typically thought that the non-native productions by adult L2 speakers are due to differences between the L1 and the L2 linguistic systems. L1 transfer, whereby phonological rules or items from the L1 are transferred to the L2, has been highly used in the literature to account for many of the non-native productions (Lado, 1957;Selinker, 1972;Odlin, 1989). This explanation, for instance, was widely used to account for errors made by Arabic L2 learners of English.
viiAccording to Broselow (1992), production errors in the L2 can be attributed either to transfer of L1 phonological rules or to the violation of some universal tendencies.Languages of the world, for instance, are different in their syllable phonotactics: On one hand, some languages are very restricted in their syllable structure by only allowing Consonant (henceforth C) + Vowel (henceforth V) sequencing; on the other hand, other languages are more flexible in allowing more complex structures. In the instances where L1 is restricted and L2 is more flexible, L1 phonotactic constraints would likely to be transferred to the L2. However, markedness has also been discussed in the literature as a plausible explanation for L2 acquisition patterns.In the discussion of the topic, markedness relationships among clusters are often determined by "implicational patterns" (Greenberg, 1965 common, as will be further discussed. The same goes for the degree of complexity by number; if a language allows three consonants to occupy the onset position or the coda position then it will necessarily allow clusters with two m...
