Question

What type of evidence did Baddeley discover in the 1970s that suggested that working memory has several components:

a) Primacy effect
b) Serial position curve
c) Phonological similarity effect
d) The dual-task paradigm

Answer 1

In the 1970s, Baddeley discovered several pieces of evidence that suggested working memory has several components: primacy effect, serial position curve, phonological similarity effect, and the dual-task paradigm.

Step-by-step explanation:

In the 1970s, Baddeley discovered several pieces of evidence that suggested working memory has several components:

1. Primacy effect: This refers to the tendency to remember items at the beginning of a list better than those in the middle or end.
2. Serial position curve: This represents the relationship between the position of an item in a list and its likelihood of being recalled.
3. Phonological similarity effect: This refers to the difficulty in remembering similar-sounding items in verbal tasks.
4. The dual-task paradigm: This involves the performance of two tasks simultaneously, which disrupts working memory performance.
