Reading rate, articulatory suppression
and bilingual digit span.
The conditions were as follows: Brooks matrix/verbal performed alone, random number generation performed alone, matrix/verbal task with articulatory suppression
, matrix/verbal task with spatial suppression, and matrix/verbal task with random number generation.
The task was completed with and without articulatory suppression
. The normal readers and the phonological recoders were more disrupted by articulatory suppression
than the whole-word poor readers.
First, we administered the LHT under three conditions: control, under articulatory suppression
, and under spatial suppression.
One possible explanation for this result is that the presence of articulatory suppression
made it more difficult to use the phonological loop, and thereby, the memorizing task became more dependent on the visual memory.
As a form to prevent the rehearsal of the stimuli in verbal terms, the participants performed an articulatory suppression
task, repeating a sequence of numbers ("1,2, 3,4" or "2,3,4, 5").
The secondary task involved articulatory suppression
. A voice key connected with a computer via the parallel port recorded time intervals between successive oral outputs of the participants.
Then, the five task conditions (single-task, articulatory suppression
, matrix-tapping, random-interval generation and fixed-interval generation) followed in one of five random orders based on a randomized Latin square.
Indeed articulatory suppression
improved rather than disrupted performance, suggesting that verbal processing hindered performance rather than improved it.
This enables the effects of irrelevant speech to be assessed in articulatory suppression
, and tests the extent to which the PL model can account for the performance of silently presented lipread items.
suppr = articulatory suppression
. The shapes of the serial position curves were further analysed using polynomial contrasts.
is a task which requires participants to utter speech sounds, so that this activity has complete overlap with speech production processes, which include speech programming, actual articulation (speech execution) and auditory feedback.
