SUMMARY:

This cross-sectional mixed-method study (Dörnyei, 2007) aims at investigating the relationship between pre-task planning, working memory capacity and L2 speech production. Fifty-six speakers of English as L2, at a pre-intermediate (n = 46) and a near-native (n = 10) level of speaking proficiency, integrated the cohort of the study. The pre-intermediate learners were exposed to a here-and-now picture-description task in which they used the L2 to described three pictures, for one minute each. Each picture was described under a pre-task planning condition. Under the no-planning condition, participants described the picture immediately, without planning their output. Under the oral and written conditions, participants planned their output for one minute prior to task performance, by orally rehearsing it or by taking notes. Speech production was analyzed in terms of complexity (number of t-units), accuracy (number of errors per 100 words), weighted lexical density (proportion of new words produced with lexical and grammatical properties) and fluency (speech rate unpruned and speech rate pruned). Planning processes were investigated by means of a delayed verbal protocol and working memory capacity was measured through the speaking span test (Weissheimer, 2007) in L1 (Brazilian Portuguese). Additionally, speech samples were analyzed through graphs in which the nodes represent the words and the edges represent the trajectory of the words produced (Mota et al., 2016, 2019). Analyses were conducted within-subjects, in order to find out which planning condition yields better results in terms of more complex, more accurate, more lexically dense and more fluent speech, and between-subjects, including memory as a factor following an extreme-group design. Graph analysis was conducted with the purpose of investigating speech production within the continuum between the pre-intermediate and the nativelike level of L2 proficiency. In general, results indicate an advantage of pre-task planning over the no-planning condition, irrespective of the modality it assumes. Speech planned under the oral and written planning conditions outscored the speech produced under the no-planning condition and the positive effects emerged with only one minute of planning. The same trend was observed when working memory capacity was included as a factor, although the two memory groups (higher and lower spans) diverged in relation to the variables most affected by pre-task planning. With regard to planning processes, participants seem to have preferred planning for a least one minute to not planning at all and identified advantages and disadvantages of the oral and written planning conditions.
