| Abstract |
| 15 TAT cards, divided into low-, medium-
and high-ambiguity groups, were administered to 30 female nursing students. Stimulus
ambiguity, defined in terms of variability of themes evoked by a given card, was found to
be associated with hesitant and disrupted speech ("ah's," a slow articulation
rate, a long reaction time, and speech disturbances). These findings are
explained in terms of the mediating role of uncertainty on speech. An adaptation
effect was noted. The later, as opposed to the earlier stories, are associated with
a longer reaction time, but fewer "ah's," less silence, and a quicker
articulation rate. Finally, significant differences are noted between Ss' verbal
fluency indexes, based on all 15 cards and thus independent of stimulus ambiguity, and
verbal fluency indexes obtained in an interview situation. These differences are
discussed in terms of monological versus dialogical speech. |
