Background

This script implements the Children's Test of Nonword Repetition (CNRep) to measure phonological working memory as used by:

Anderson, J.D, Wagovich, S.A., & Hall, N.E. (2006). Nonword repetition skills in young children who do and do not stutter. J Fluency Disord, 31(3), 177–199.

The test was originally described in:

Gathercole, S.E., Willis, C.S., Baddeley, A.D., & Emslie, H. (1994). The Children’s test of nonword repetition: A test of phonological working memory. Memory; 2:103–127.

The described test (Anderson et al, 2006) uses a tape-recorded (randomly assembled) sequence of nonwords with each word being separated by a 4s time interval. If a child needed more time to respond, the tape was paused (Anderson et al, 2006).

This script adapts this procedure to the computer with the following procedural differences: - unlimited time to respond to each nonword (the response latency is measured). - As any utterance at the point of recording is taken as a response the experimenter has to accept the response by pressing the to advance to the next nonword trial. By pressing , the experimenter has the option to repeat the previous trial.

Duration

7 minutes

Description

Participants hear made-up English words and have to repeat them out loud. Trials can be repeated if deemed necessary by experimenter. A practice run presents made-up and real English words.

Procedure

• 1 Instruction Block
• 1 Practice Block
• 1 Experimental Block

EXPERIMENTAL BLOCK:
• 1 block a 40 trial sequences

EXPERIMENTAL TRIAL SEQUENCE:
trial.CNRep_nonwords -> trial.accept -> a) Spacebar: next trialsequence (new nonword)
b) Enter: trial.repeatnonword -> trial.accept-> a) Spacebar: next trialsequence (new nonword)
b) trial.repeatnonword

•trial.CNRep_nonwords: the next nonword is chosen. Any utterance is recorded as the response
• latency is recorded.
• by default items are called in sequence (-> Gathercole et al., 1994), this can be changed under STIMULI-> sound.nonword
•Experimenter has control over whether to accept the current response or whether to repeat the trial

Stimuli

• 40 nonwords, 10 items each with 2, 3, 4 and 5 syllables

!!!IMPORTANT: the sound files provided with this script are only intended for DEMONSTRATION PURPOSES
and we STRONGLY suggest using your own sound recordings.
• sound files can easily be exchanged under EDITABLE CODE -> Editable STIMULI-> item.nonwords
(as well as practice items: EDITABLE CODE -> Editable STIMULI-> item.practiceitems)

practice:
• 1 Block with 10 trial sequences
• 5 words and 5 nonwords (NOT original) make up the practice items
• practice stimuli are drawn in sequence (->fixed randomly assembled sequence)
• Practice trial sequence similar to experimental trial sequence

Instructions

• instructions are not original
