An examination of the lateralized abstractive/form specific model using MiXeD-CaSe primes.

CaSe AlTeRnAtIoN effects on the two cerebral hemispheres were studied in a lateralized visual lexical decision task with 32 right-handed participants. The study aimed to compare two well-known lateralization theories, the two processing modes and the abstractive/form-specific theories, that differ in the predictions regarding case alternation effects on the hemispheres. The experiment employed the masked priming paradigm, where prime and target words were presented in mixed case. The results of the experiment demonstrated no hemispheric differences in priming size when prime and target were similar in (mixed) case, thus were in line with the two modes theory. However, a new interpretation to the abstractive/form-specific model may also account for the results.
