Original Complex Figure Drawing Task
After https://en.wikipedia.org/wiki/Rey%E2%80%93Osterrieth_complex_figure:
The Rey–Osterrieth complex figure test (ROCF) is a neuropsychological assessment in which examinees are asked to reproduce a complicated line drawing, first by copying it freehand (recognition), and then drawing from memory (recall). Many different cognitive abilities are needed for a correct performance, and the test therefore permits the evaluation of different functions, such as visuospatial abilities, memory, attention, planning, working memory and (executive functions). First proposed by Swiss psychologist André Rey in 1941 and further standardized by Paul-Alexandre Osterrieth in 1944, it is frequently used to further explain any secondary effect of brain injury in neurological patients, to test for the presence of dementia, or to study the degree of cognitive development in children.
MindLogger implementation
This task consists of three phases, each related to the Rey-Osterreith Complex Figure. In the first phase, Copying, the user is presented with the figure, and asked to simply copy the figure as accurately as possible. When the user finishes copying the figure, it is removed from view. The second phase, Immediate Recall, begins immediately following the first phase; the user is now asked to reproduce the figure from memory. Once the user finishes drawing the figure from memory, they can perform other tasks for about 30 minutes. At that time, the user is asked to complete the final phase, Delayed Recall, by once again drawing the figure from memory. The user will not be shown the figure after the initial Copying phase is completed.
The phases of the task are not typically time-limited, but normative data from a Canadian sample of 50- to 90-year-old community dwelling participants showed mean copy times of 4 minutes with a 90-second standard deviation. If users exceed 5 minutes on the task, that phase of the task ends.
Copy Instructions
Please copy this design in the space below. Do not worry if your copy is not perfect. Just do the best that you can to copy the figure as accurately as possible.
Once the user indicates that they are done, the figure and drawing canvas are removed. The Immediate Recall instructions are displayed.
Immediate Recall Instructions
Please draw as much as you can remember of the design as accurately as possible.
Users Press a button to begin, and if they exceed 5 minutes on the task, that phase of the task ends.
Once the user indicates they are done, the drawing is removed and they can move on to other tasks for about 30 minutes. After that time, they will perform the Delayed Recall phase. We do not tell the users that we will ask for another drawing later.
Delayed Recall Instructions
Earlier you copied a design and you were asked to draw as much as you could remember of the design. Please draw as much as you can remember of the design again, as accurately as possible.
