Historical Background and Development
Origins and Evolution
The origins of the Rey-Osterrieth Complex Figure date back to the 1940s. André Rey, a Swiss neuropsychologist, initially developed the figure as part of his effort to assess memory and visual-spatial skills in individuals with brain injuries. His original test, known as the Rey-Osterrieth Figure, was designed to evaluate visual constructive abilities and visual memory through copying and recall tasks.
In the 1940s and 1950s, Paul Osterrieth expanded upon Rey's work, refining the figure and establishing standardized procedures for administration and scoring. Over time, the test gained popularity due to its robustness in detecting various cognitive deficits, especially those related to right-hemisphere brain function.
Significance in Neuropsychology
The Rey-Osterrieth Complex Figure has become a pivotal tool because it taps into multiple cognitive domains, including:
- Visual-spatial processing: Understanding how individuals perceive and organize visual information.
- Memory: Assessing recall and recognition of complex visual stimuli.
- Executive functions: Evaluating planning, organization, and problem-solving abilities during copying and recall tasks.
Its widespread use is due to its sensitivity to neurological conditions such as stroke, traumatic brain injury, dementia, and developmental disorders.
Structure and Components of the Test
The Rey-Osterrieth Complex Figure
The figure itself is a complex, abstract drawing that incorporates geometric shapes, lines, and patterns. It is designed to be challenging enough to reveal subtle deficits in visual-spatial and memory functions.
The figure is typically presented as a single sheet containing various interconnected shapes, including:
- Circles
- Triangles
- Lines
- Curves
- Other geometric forms
The complexity requires the examinee to analyze, organize, and reproduce the figure as accurately as possible.
Test Procedures
The Rey-Osterrieth assessment involves three main phases:
- Copying Phase: The individual is asked to copy the figure as accurately as possible while viewing it. This phase assesses visuo-constructive abilities and organizational strategies.
- Immediate Recall Phase: After the copying task, the individual is asked to reproduce the figure from memory immediately. This gauges immediate visual memory.
- Delayed Recall Phase: After a time delay (usually 20-30 minutes), the individual reproduces the figure again from memory. This evaluates longer-term visual memory retention.
Some versions also include recognition tasks, where the examinee identifies the original figure among distractors, further assessing visual recognition memory.
Administration and Scoring
Administering the Test
Standardized administration procedures are crucial for obtaining valid and reliable results. The process involves:
- Providing clear instructions to the examinee.
- Presenting the figure on a sheet of paper or a card.
- Allowing sufficient time for copying, typically 3-5 minutes.
- Ensuring appropriate time intervals between the copying and recall phases.
- Maintaining a quiet, distraction-free environment.
It's important to observe the examinee's approach, noting strategies used, such as whether they segment the figure or attempt to reproduce it holistically.
Scoring Methods
Scoring the Rey-Osterrieth figure can be both qualitative and quantitative. Common approaches include:
- Qualitative Analysis:
- Observing organizational strategies.
- Noting errors such as omissions, distortions, or misplaced elements.
- Assessing spatial accuracy and overall organization.
- Quantitative Scoring:
- Using standardized scoring systems, such as the 18-point or 36-point scales, which assign points based on the presence and accuracy of specific components.
- Scoring the accuracy of reproduction in terms of shape, size, placement, and detail.
- Evaluating the degree of integration and planning reflected in the drawing.
Some practitioners also rate the test based on error types, such as perseveration, omissions, or perseverative errors, which provide insights into specific cognitive deficits.
Interpretation of Results
Normal vs. Impaired Performance
Interpreting the Rey-Osterrieth complex figure involves comparing the examinee's performance to normative data considering age, education, and cultural background.
- Normal Performance:
- Reproduces the figure with high accuracy.
- Demonstrates organized, logical construction strategies.
- Shows good recall in immediate and delayed phases.
- Impaired Performance:
- Omissions or distortions in the figure.
- Disorganized or fragmented reproductions.
- Poor recall, especially in delayed tasks.
- Use of inefficient strategies or perseverative behaviors.
Identifying Cognitive Deficits
Different patterns of errors can point to specific neurological or cognitive issues:
- Right Hemisphere Damage:
- Visuo-spatial deficits leading to poorly organized reproductions.
- Omissions of details or misplacements.
- Memory Impairments:
- Difficulties in recall phases.
- Increased errors in delayed reproduction.
- Executive Dysfunction:
- Poor planning and organizational strategies during copying.
- Perseveration or perseverative errors.
