We constantly use our senses to categorize stimuli in our environment. We develop categories for stimuli when we are young and con stantly add to existing categories and learn novel categories throughout our lives. Learning novel sound categories can be easy or very challeng ing depending on a number of factors, such as the learning methodology u sed and the learner’s previous auditory experience. Traditional novel so und category learning paradigms utilize explicit instruction regarding t he target categories and immediate trial by trial feedback, with trainin g sessions spanning days or weeks. However, novel sound category learnin g can also occur incidentally, with training and testing occurring in a single session. Thus far, incidental auditory category learning has been limited to synthesized sound categories. In the present research, I inv estigate the formation of four novel Thai tone categories using natural tokens and an incidental learning paradigm. Throughout the experiments I demonstrate that native English participants with no prior experience w ith the target tone categories, from 18 to 66 years old, can use an inci dental learning paradigm with natural tokens to form four novel tone cat egories after 30 minutes of training with very high, even perfect, accur acy. These findings confirm results from previous studies that suggest t hat participants can effectively learn novel sound categories through in cidental learning paradigms. Further, I use the incidental learning para digm across four experiments to examine factors known to impact novel so und category acquisition. I demonstrate that 1) the temporal proximity o f acoustic variability impacts learning, 2) talker variability during tr aining impacts categorization and generalization ability, 3) segmental f amiliarity during incidental learning does not impact novel tone categor y formation, and 4) production of the tokens on each trial destroys perc eptual learning.
