Objective: To revise the original ‘Reading the Mind in the Eyes’ Test to improve psychometric properties and detect social cognitive dysfunction in adults, particular in those with Asperger syndrome (AS) or high-functioning autism (HFA).

Previous Work (1997): Initial version of the ‘Reading the Mind in the Eyes’ Test developed to measure adult mentalising.
Challenge: The original test, while effective, had psychometric limitations that necessitated refinement for better discrimination between individuals with AS or HFA and control groups.

Mentalising: Refers to the ability to attribute mental states (beliefs, intents) to oneself and others; essential for understanding and predicting behavior. - Theory of Mind: Shorthand for mentalising (Premack & Woodruff, 1978); overlaps with empathy, social cognition, and social intelligence. - Terms Used: Also referred to as ‘mind reading’ and ‘social intelligence’.
Importance of Social Cognition: Understanding nuances in social interactions, especially in clinical populations, is critical as deficits can mask underlying issues.

Original Test Description: In the original ‘Reading the Mind in the Eyes’ Test, participants viewed 25 photographs focusing on actors' eyes and chosen corresponding words describing the mental state depicted.
**Psychometric Issues Identified: 1. *Forced Choice and Chance Performance:* Only two response options led to narrow assessment capacity. A score of 17/25 was needed to surpass chance. 2. Broader Phenotype in Parents: Parents of individuals with AS or HFA also scored poorly due to potential genetic contributions leading to confounding scores. 3. Ceiling Effects: Risk of normal scores nearing the possible maximum, which limits detecting individual differences. 4. Basic vs Complex Mental States: Included basic emotions which risked ceiling effects as they could easily be determined. 5. Gaze Direction Clue: Some items could be solved by directional gaze rather than understanding mental state. 6. Gender Imbalance in Faces: More female than male faces raised potential biases in test responses. 7. Semantic Opposites Challenge: Original test utilized semantic opposites making differentiation too simplistic. 8. Word Comprehension Issues: Concerns about comprehension when identifying mental states among participants with language delays.

**Modifications Implemented:
1. Increased items from 25 to 36 photographs. 2. Expanded response options from 2 words to 4 responses per item. 3. Focused solely on complex mental states to increase difficulty. 4. Excluded items based on gaze direction for clues. 5. Ensured equal gender representation among photographs. 6. Avoided semantic opposites for target and foil words, utilizing close emotional valence instead. 7. Included a glossary for mental state terms to enhance comprehension.

Participants: - Group 1: Adults with AS or HFA (N¯15). - Group 2: General population controls (N¯239). - Group 3: University students (N¯103). - Group 4: IQ matched controls (N¯14).
Procedure: Each group individually underwent testing in controlled environments; groups 1, 3, and 4 completed the Autism Spectrum Quotient (AQ).

Group Performances: The revised test succeeded in distinguishing AS/HFA from normal controls. - Adult males (General Population) mean score: $18 \footnotesize{ ext{±}} ext{8 (SD } ext{±}2.5)$ - Adult females mean score: $21 \footnotesize{ ext{±}} ext{8 (SD } ext{±}1.8)$ - AS/HFA scored lower than sex-matched controls, mean: $16 \footnotesize{ ext{±}} ext{3 (SD } ext{±}2.9)$ compared to $20 \footnotesize{ ext{±}} ext{4 (SD } ext{±}2.6)$ for TS controls.
Statistical Significance: Improvements resulted in group differences becoming statistically significant at the $p < 0.01$ level.

Utility of Revised Eyes Test: Validated as a sensitive measure for social cognition, the study emphasized the test's ability to reveal subtle differences in a population often viewed as high-functioning.
Clinical Implications: Suggest that the Revised Eyes Test may extend utility beyond autism to assess social cognition in other neurological conditions.
Sex Differences: Statistical analysis revealed a trend toward female superiority in testing accuracy.
Correlations: Inverted relationships between test scores and AQ indicate potential for using both measures in broader psychological evaluations.

Significant Findings: The revised test demonstrated improvements in sensitivity and psychometric reliability over the original version. Test results confirmed expected differences between populations indicating its functional validity.
