STUDIES - Baddeley, Lewis, and Vallar (1984)

Question 1

Introduction

Answer 1

• Experiment

Question 2

Aim

Answer 2

Explore effects of articulatory suppression on the phonological similarity effects

Question 3

Procedure

Answer 3

METHOD
Participants had to recall word lists whilst blocking inner voice:

• Spoken mode of presentation:
  1) C1: Rhyming words
  2) C2: Non-rhyming words
• Written mode of presentation:
  3) C3: Rhyming words
  4) C4: Non-rhyming words

Question 4

Results

Answer 4

• Phonological similarity effect between conditions 1 and 2 (1 was harder to recall)
• No phonological similarity effect between conditions 3 and 4 (equally recalled)

Question 5

Findings

Answer 5

When articulatory rehearsal is inhibited (articulatory suppression):

• Spoken information can still enter phonological store (inner ear) directly
  1) Rhyming words create similar traces so easy to confuse
  2) Yes phonological similarity effect
• Written information enters visuospatial sketchpad instead as it doesn’t get recorded into sounds
  1) Information is coded visually so traces are hard to confuse
  2) No phonological similarity effect
