Conditions

Three conditions are most commonly used in the ROCF. In the Copy condition, the examinee is given a piece of paper and a pencil, and the stimulus figure is placed in front of them. They reproduce the figure to the best of their ability. The test is not timed, but the length of time needed to copy the figure is observed. Some administrators use a series of colored pencils, in order to preserve a record of the order in which design elements were reproduced. However, because of concerns that the use of color changes the nature of the test and makes it easier for the subject to remember the figure, the current test manual suggests that this not be done, but that the evaluator take notes on the process the examinee uses. Once the copy is complete, the stimulus figure and the examinee's copy are removed from view. In the Immediate Recall condition, after a short delay, the examinee is asked to reproduce the figure from memory. After a longer delay (20–30 minutes), the examinee may again be asked to draw the figure from memory. Examinees are not told beforehand that they will be asked to draw the figure from memory; the Immediate and Delayed Recall conditions are therefore tests of incidental or implicit memory

. Each copy is scored for the accurate reproduction and placement of 18 specific design elements. Additionally, qualitative observations regarding the examinee's approach to the task and the effectiveness of any apparent strategy use can be noted.

André Rey

At the dawning of the 1940s, psychologists throughout the world were having difficulty in eliciting the specific deficits exhibited by individuals (both adults and children) who had experienced traumatic brain injury. In 1941, the Swiss psychologist André Rey was working at the Université de Genève in Geneva, and he recognized this necessity of differentiating between "primary effects, which are a direct result of the insult to the head, and the secondary effects, which develop out of subjective reactions determined by the loss of awareness from the physical impairment

s
". One of the many forms of assessment that Rey detailed in his 1941 report was a complex figure composed of many different shapes, line segments, and other elements.

Paul-Alexandre Osterrieth

In 1944, Paul-Alexandre Osterrieth, who had worked as a research assistant under André Rey at the Université de Genève, utilized the figure Rey had developed in his work with young children. Osterrieth proposed to subcategorize the figure into 18 elements and score them based on their presence, completeness, and correct placement. This 18-point scoring system is still commonly used today in evaluating an examinee's performance on the ROCF test.

Unlike Rey, Osterrieth was primarily interested in the measure as an assessment of whether or not children had developed the concept of a holistic or gestalt

 principle by various ages, as manifested by the way they approached the figure drawing. Based on his experimentation, Osterrieth recognized several important trends. Specifically, he noticed that the principle of gestalt seems to stabilize around the age of nine years in children. Also, he noted several different approaches that the children used in constructing the figure, each of which appears to be roughly correlated with a particular age group:
  • Primitive forms that show "distorted integration" and "confabulations" in their drawings.
  • Children who showed an awareness of specific concepts while still remaining unaware of the overall figure.
  • Complete awareness of the overall figure.

Additionally, Osterrieth noticed that strategy was a good predictor of the child's performance on all three of the various tasks.

Edith Taylor

In 1959, child Psychologist Edith Taylor gave more elaborate descriptions on the 18-point scoring system initially proposed by Osterrieth. She had also briefly worked with Rey in Geneva and credited him with inspiring her to pursue this particular aspect of psychology.

Laughlin B. Taylor

In 1969, Laughlin B. Taylor developed a second complex figure that is comparable to Rey's and can be therefore used to eliminate the memory effect in a second evaluation.
Explicit scoring criteria based on the Taylor-Osterrieth method have been developed for both the Rey-Osterrieth and Taylor Complex Figure Tests, although the Taylor figure has been found to be more easily remembered than the Rey-Osterrieth, calling into question their interchangeability.
