Protocol - Visual Memory - Adult

Add to My Toolkit
Description:

Visual Reproductions is an interviewer-administered test that is a part of the Wechsler Memory Scale® Fourth Edition (WMS®-IV). The interviewer shows the respondent a series of simple images and asks the respondent to draw them from memory. The test can be performed as both an immediate and delayed recall. The protocol includes scoring instructions that account for accuracy and speed.

Protocol:

Immediate Recall

The examiner shows the respondent a picture for 10 seconds and then gives the respondent a piece of paper and instructs them to draw the picture from memory. This is repeated three times with different images. The first two pictures contain a single image, but the last picture contains two images that are side by side.

Delayed Recall

After a predetermined amount of time, examiner asks the respondent to draw as many pictures as they can recall. The respondent is informed the pictures do not have to be drawn in the same order as they were shown. After completing these drawings, the respondent is asked which image they were shown first.

Definition

An interviewer-administered test that measures the ability of the respondent to remember images and pictures.

Purpose

This measure tests a respondent’s total range of function with respect to visual memory. It is therefore more specific and sensitive than a measure of global mental status and can be used to assess major problems in visual memory as well as minor variations that may be a consequence of normal development and aging.
