Hysteresis in reach planning and spatial demonstrative choice

Recent studies have demonstrated hysteresis in studies of syntactic choice in language production. These studies further show that the hysteresis effects observed in syntactic choice are similar to the effects observed in motor choice tasks. Here, we examine whether hysteresis can be observed for a different kind of linguistic choice, namely the choice between the spatial demonstratives this and that. We further examine whether these hysteresis effects parallel the hysteresis effects found in a similar motor task. Our results demonstrate hysteresis in both spatial demonstrative choice and motor choice. Nevertheless, there were some effects that appeared in the motor task that did not appear in the language task (e.g., a response time advantage for repeated choices).
