The RFFT was developed to provide clinical information regarding nonverbal capacity for fluid and divergent thinking, ability to shift cognitive set, planning strategies, and executive ability to coordinate this process.

Features and benefits

  • The test booklet consists of five 60-second parts, each with a different stimulus presentation.
  • The respondent draws as many unique designs as possible within 60 seconds by connecting the dots in different patterns. The total number of unique designs drawn constitutes the main score.
  • The Perseverative Errors score represents the number of repetitions of the same pattern drawn by the respondent.
  • The Error Ratio index assesses the respondent’s ability to minimize repetition while maximizing unique productions.
  • Qualitative strategies, such as rotation and enumeration, can also be assessed.

Note: Stopwatch is required for administration.
