Psychology Investigated: Theory of mind, specifically in adults with Asperger's syndrome or autism.

Background: The "Reading the Mind in the Eyes" Test (RMET) was originally developed in 1997 as a measure of theory of mind.

Aim: To investigate the performance of adults with Asperger's syndrome or high-functioning autism on a revised version of the RMET.

Procedure: Participants were presented with photographs of people's eyes and asked to identify the emotion being expressed.

The revised RMET included a broader range of emotions and more challenging images.

Sample: 36 adults with Asperger's syndrome or high-functioning autism.

31 control participants.

Sampling Technique: Not specified.

Experimental Design: Independent measures.

Controls: Control participants without Asperger's syndrome or autism.

Ethical Issues: No significant ethical concerns were raised.

Results: The study found that adults with Asperger's syndrome or high-functioning autism performed significantly worse on the revised RMET than the control group.
