The effects of familiarity and practice on naming pictures of objects.
Ss were given a paired-associate learning task, using nonsense shapes as stimuli and object names which varied in Thorndike-Lorge frequency as responses. Between each block of learning trials, Ss named the nonsense shapes and a set of line drawings of objects. While naming latencies for the shapes were unaffected by name frequency, there was an effect of frequency on naming a control set of pictures of objects. The frequency effect for the pictures decreased significantly with practice. When the Ss were asked to name pictures of the objects having the names previously learned for the nonsense shapes, an effect of frequency appeared, the size of the effect being the same as that found for the control pictures after practice. The frequency effect disappeared when the shapes were reintroduced.
