Gesture, speech, and lexical access: the role of lexical movements in speech production

Article Abstract:

The use of gestures enhances fluency in speech with spatial content by facilitating access to mental lexicon. Speakers become more fluent when allowed to use gestures and use them more often during phrases with spatial content. Prevention of using gestures causes repeated occurrence of nonjuncture filled pauses in speech with spatial content. However, such prevention hardly affects the quality of speech with nonspatial content. The effects of prevention resemble those that result due to an increase in the difficulty of lexical access.

The effect of inhibition of return on lexical access

Article Abstract:

Two experiments were conducted to determine whether inhibition of return takes place in tasks where complex discriminations including categorization and lexical decision tasks are required. A sample of 10 undergraduate students was asked to examine if a string of letters formed a word or a nonword. Results indicate that inhibition of return can also influence the processing required for lexical access, in addition to inhibiting returning attention to previously attended locations.

Vocal expression of emotion: acoustic properties of speech are associated with emotional intensity and context

Article Abstract:

The acoustic properties of speech may be used to mediate the vocal expression of emotions. The analysis of fundamental frequency and two perturbation measures shows major differences between baseline and on-task values. This result has considerable potential for theoretical advances in the study of emotional processes. The relationship between vocal emotions and emotive facial expression needs to be evaluated for further studies.
