Abstract: | Previous studies suggested that the linear relation between RT and presented information found for equally likely stimuli (ELS) did not hold for unequally likely stimuli (ULS). In fact, RT to low-information stimuli in the ULS condition was higher than RT to the same stimuli information in the ELS condition. A possible explanation of the discrepancy between the 2 functions is that sequential effects were not the same in the 2 conditions. This hypothesis was partially supported in an experiment involving 9 right-handed university students in a situation in which the possibility of a sequential effect was drastically reduced. A methodological approach permitting the reduction of sequential effects is proposed. (28 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
