Study Arms (7)

Aim 1, Sentence Training: Sentence Feedback

EXPERIMENTAL

In Aim 1, which is sentence lipreading training, the intervention compares the provision of three different types of feedback for lipreading. This arm gives printed whole sentence feedback following an attempt to lipread each sentence. Participants receive pre- and post-training tests.

Behavioral: Speech Recognition Training

Aim 1, Sentence Training: Word Feedback

EXPERIMENTAL

In Aim 1, which is sentence lipreading training, the intervention compares the provision of three different types of feedback for lipreading. This arm gives printed whole word feedback following an attempt to lipread each sentence. Word feedback is for correct words and words that are perceptually similar but incorrect responses. Participants receive pre- and post-training tests.

Behavioral: Speech Recognition Training

Aim 1, Sentence Training: Consonant Feedback

EXPERIMENTAL

In Aim 1, which is sentence lipreading training, the intervention compares the provision of three different types of feedback for lipreading. This arm gives printed consonant word feedback following an attempt to lipread each sentence. Word feedback is for correct words, but only the consonants are given as feedback for words that are perceptually similar but incorrect responses. Participants receive pre- and post-training tests.

Behavioral: Speech Recognition Training

Aim 1, Sentence Training: No Training Control

NO INTERVENTION

Participants receive only the pre- and post-training tests.

Aim 2, Nonsense Word Training

EXPERIMENTAL

Participants train to lipread nonsense words that name nonsense pictures. Participants receive pre- and post-training tests.

Behavioral: Speech Recognition Training

Aim 3, Audiovisual Nonsense Word Training

EXPERIMENTAL

Participants train to recognize audiovisual spoken nonsense words that name nonsense pictures and are presented in speech-shaped noise. The paradigm is the same as in Aim 2. Participants receive pre- and post-training tests.

Behavioral: Speech Recognition Training

Aim 3, Audiovisual Sentence Training

EXPERIMENTAL

Participants receive the same training paradigm from Aim 1 with the most effective feedback type from Aim 1. But the sentences are audiovisual and in speech-shaped noise. Participants receive pre- and post-training tests.

Behavioral: Speech Recognition Training

Interventions

Speech Recognition Training BEHAVIORAL

Training for each training arm takes place over 10 sessions carried out at home. on the participant's own computer without experimenter direct supervision. Pre- and post-training tests are carried out under experimenter supervision.

Model Details: In Aim 1, which is sentence lipreading training, the intervention compares the provision of three different types of feedback for lipreading. The three types are consonant-level, word-level, or sentence-level feedback. A no-training wait-list control is included. In Aim 2, novel word training, the intervention has one arm in which novel word learning via lipreading the words is supported by allowing the participants to read the consonants in the novel words before lipreading them. In Aim 3, the most effective feedback with sentence training will be compared with novel word training using training stimuli that are audiovisual speech in speech-shaped noise. The interventions are all delivered individually via the web. Finally, all pre- and post-training results will be compared across groups including the wait-list controls.
