Stimulus Pull in Rorschach Inkblots

The study on which this article is based examined whether there was a stimulus pull in each Rorschach inkblot and whether this phenomenon operated differently among individuals in three groups. The study’s 105 participants included a clinical sample of individuals with longstanding substance abuse problems in the United States (US) and two groups of university students – one group from the US and the other from the Caribbean. To assess the stimulus pull in each Rorschach inkblot, the Rorschach Association Technique (RAT) was developed. The RAT’s content was based on what the Rorschach literature cited as the stimulus pull of each of the 10 inkblots. It was administered individually to each participant and used a multiple choice format in which participants were asked to indicate from the 10 options, the stimulus pull of the 10 inkblots. A participant could use a stimulus pull more than once. Overall, the data did not support a universal stimulus pull for the specific inkblots. A participant could use a stimulus pull more than once. Overall, the data did not support a universal stimulus pull for the specific inkblots. Additionally, the degree of stimulus pull varied across the 10 inkblots. Also, there were no differences in the degree to which individuals from the different groups cited the expected stimulus pull.
