Abstract [en]

Two experiments will be presented which assessed free recall of spoken words in Swedish (native tongue) and in English heard under different signal-to-noise ratios (SNR: +3 and +12 dB), and different reverberation times (RT: 0.3 and 1.2 s). All participants encountered these eight experimental conditions (Language*SNR*RT). The first experiment was run with college student (N=48), who were run individually. In the second experiment children in grade 4 (10-11 years, N=72) took part and they were run as a group in their regular classrooms.

Twelve wordlists in English and twelve wordlists in Swedish were generated. The words were chosen according to their ranks in category norms for the two languages. The number of words in each list was 12 for the college group and 8 for children in Grade 4. The 2 x 12 wordlists were presented in counter balanced presentation orders in three blocks (Blocks). To compare primacy and recency effects the word lists were divided into three parts (p3rd). After each wordlist the participants typed in or wrote down the words they could recall.

The basic hypotheses for the recall of the words were that working memory would be overloaded when the SNR was low and the RT was long, and that SNR and RT would interact with each other, with Language and with Study (Grade4/College). The analyses suggest that for both groups there were expected effects of language and of SNR, but the effect of RT was smaller and only showed up in interactions.
