L2 Perception

Abstract This study compared children’s and adults’ L2 perception and production in the first hours of exposure to a foreign language. A total of 10 German children and 19 German adults performed a phoneme discrimination task and a sentence imitation task in Polish at two testing times. Exposed to a comparable input, the adult learners were found to perceive Polish sibilant contrasts more accurately than their child counterparts and to maintain this advantage over a two-week-long instruction. However, the two groups did not differ in their developing ability to produce the tested sibilants. A great deal of inter- and intra-individual differences in both learner groups was also attested. Our findings suggest that young L2 instructed learners are not necessarily better and/or faster perceivers and producers of novel language sounds than adult L2 instructed learners, who are able to discriminate a range of novel sibilant pairs even after very limited L2 exposure.

Rate Of Accumulation

Vickers et al. (1972) proposed that three main determinants of perceptual organization are the inspection time λ governing the rate of accumulation of sensory data, the noise in the visual system sD, and the degree of caution adopted for responding. The mean overall latency of judgments in a simple psychophysical discrimination task L was suggested to provide a satisfactory indirect index of caution. Differences between individuals in these three behavioural descriptors, together with an index of the use made of immediate memory δ, were compared with personality measured by the Manifest Anxiety Scale and the Eysenck Personality Inventory. Results from two experiments confirmed the independence of λ, sD, L, and δ as indicators of individual differences. The relationships between these measures and scores on the personality scales were clear, but not always straightforward. They are examined in terms of interactions between the processes underlying the measures.
