“…There are inherent challenges in using rating and self-assessments because assessors must be congruent and unbiased, and participants tend to overrate their performance and therefore, the method has been proven unreliable [ 123 , 124 ]. Some studies ( n = 21) used video recording and blinded assessors [ 47 , 48 , 54 , 58 , 60 , 61 , 63 , 66 , 70 , 71 , 74 , 76 , 89 , 91 , 98 , 99 , 103 , 106 , 108 , 111 , 114 ], which increased the validity of the ratings; because the assessors’ could rewind the video and review the situation multiple times. Other studies rated participants in real-time, which challenged the assessors’ ability to simultaneously watch, listen and rate [ 10 , 49 – 51 , 53 , 57 , 59 , 62 – 65 , 67 , 68 , 72 , 73 , 75 , 77 – 79 , 81 , 85 , 93 , 96 , 101 , 107 , 115 , 125 ].…”
