Temporal variables for a student before and after visiting
(adapted from Raupach, 1987)

total speaking time

 pause/time ratio

 run length









Research summary: Raupach, M. (1987), 'Procedural learning in advanced learners of a foreign language', in Coleman, J., & Towell, R. (eds.), The Advanced Language Learner, CILTR, London, 123-156
Aim: application of temporal variables to L2 speech
Learners: adult German learners of French
Aspect of language: temporal variables of pauses, run-length, speaking time etc
Data type: interviews transcribed with pauses etc
Results: improvement on measures of fluency after visiting France
Conclusions: Anderson's view of learning as shift from declarative to procedural memory is complicated in L2 learning by the possibility of L1 transfer and translation

Improvement in L2 temporal variables over time (adapted from Towell, 1987a p.168; 1987b, p.124) * % of runs from 1-4 sylls

Anderson’s ACT* model

Types of memory
– working memory (used for performance)
– declarative memory (stores isolated ‘facts’)
– procedural memory (stores processes production rules) handling ‘facts’)

Stages of learning in ACT*
1) the declarative stage (sometimes called the ‘cognitive ‘stage)
2) the knowledge compilation stage (sometimes called ‘associative’)
3) the tuning productions stage (sometimes called ‘autonomous’)

Research summary: Hulstijn & Hulstijn Language Learning, (1984)
: to investigate control and metacognitive dimensions via factors of Time Pressure and Attention to Form
Learners: 32 learners of Dutch (from a larger sample of 157)
Linguistic Content: Dutch syntax involving 'Inversion' (Verb Second) and 'Verb Final' (SOV in subordinate clauses)
Design: variation of Time Pressure (Fast/Slow) and Focus on Form (Information/
Data type: retelling 68 stories following prompts to elicit Inversion or Verb Final, plus follow-up interviews
Method of analysis: response length and information content scores
Results: Attention (i.e. Focus on Form) had an effect, Time pressure (Fast/slow) did not; extra time helped both those who knew the rules explicitly and those who did not

Inversion (%) Verb Final (%)
1) Information/Fast 81.0 36.12
2) Information/Slow 77.6 37.6
3) Grammar/Fast 85.7 55.7
4) Grammar/Slow 87.9 59.1
Scores for Inversion and Verb Final
