Sentence Context and Word-Picture Cued-Recall Paired-Associate Learning Procedure Boosts Recall in Normal and Mild Alzheimer’s Disease Patients

الملخص EN

Introduction.

The aim of this study was to employ the word-picture paradigm to examine the effectiveness of combined pictorial illustrations and sentences as strong contextual cues.

The experiment details the performance of word recall in healthy older adults (HOA) and mild Alzheimer’s disease (AD).

The researchers enhanced the words’ recall with word-picture condition and when the pair was associated with a sentence contextualizing the two items.

Method.

The sample was composed of 18 HOA and 18 people with mild AD.

Participants memorized 15 pairs of words under word-word and word-picture conditions, with and without a sentence context.

In the paired-associate test, the first item of the pair was read aloud by participants and used to elicit retrieval of the associated item.

Results.

The findings suggest that both HOA and mild-AD pictures improved item recall compared to word condition such as sentences which further enabled item recall.

Additionally, the HOA group performs better than the mild-AD group in all conditions.

Conclusions.

Word-picture and sentence context strengthen the encoding in the explicit memory task, both in HOA and mild AD.

These results open a potential window to improve the memory for verbalized instructions and restore sequential abilities in everyday life, such as brushing one’s teeth, fastening one’s pants, or drying one’s hands.
