Abstract:
Abstract: Automatization of vocal responses to visual stimuli
is involved in learning to read. One way to examine the degree to
which vocal responses are automatized is through implicit learning.
Although implicit sequence learning is typically assessed with a
serial reaction time (SRT) task in which buttons are pressed in
response to illuminated locations on a computer screen, the present
study examined implicit sequence learning during a rapid naming
task. In the rapid naming task, responses were vocalized names for
pictures presented in a repeating temporal sequence. Participants
first completed a random session in which pictures of common
objects or colors were randomly ordered. In the second session,
participants performed the object and color naming tasks when items
were repeated in a specific pattern. To assess sequence learning,
participants were switched back to the randomly ordered pictures at
the end of the pattern session. Naming reaction time significantly
increased when participants were switched from pattern to random
blocks, indicating implicit learning of the sequence. When two
individuals who expressed explicit knowledge of at least half of
the pattern as assessed with free or cued recall were removed from
analyses, the increase in naming reaction time for random blocks
persisted. These results indicate that the naming system is
sensitive to implicit temporal sequences and may help in
understanding automatization of vocal responses to visual stimuli.
