Vowel-Contingent Anchoring Effects on the Perception of Stop Consonants

The vowel-contingent effect in the anchoring paradigm was examined. Two experiments were conducted to investigate (1) the vowel-contingent effect in the anchoring effect upon the perception of voiced stop consonants and (2) the duration of vowel-contingent anchoring effects. Anchors were presented to fifteen subjects as a part of the stimulus series in Experiment 1 and to five subjects as a preceding stimulus to one of the stimulus series in Experiment 2. Two conditions of interstimulus interval between anchor and target were employed: 1.0 s and 3.0 s. The vowel-contingent anchoring effect was obtained in both of the presentation conditions. More effetcs were obtained when the acoustical similarity between the anchor and stimulus series increased. It was also found that the vowel-contingent anchoring effect decreased when the ISI was 3.0 s. The present results suggest that vowel-contingent anchoring effects occur at the auditory level irrespective of their phonetic code.
