Studies have shown clothing comfort can effect understanding and performance. Student scores on statistics exams were compared with comfort ratings. Prior to the exam, students rated their confidence in taking the exam, number of hours studied, comfort level, type of clothes being worn, and other relevant variables.
To maintain naturalistic conditions, clothing was not manipulated but was self-selected. As expected, the more formal the attire, the lower the comfort rating of that attire and the lower the exam score. Therefore, the higher the comfort rating of the attire, the higher the exam score. This study provides further evidence of a relationship between perceived clothing comfort and cognitive performance.
