Two of the 16 participants responded with 'disagree/very difficult' on five items, which suggested that they had difficulty, or were unable to complete that task.
This possibility may at least partly explain the poor psychometric properties of the professionalism items, which suggest that SRQs may not be an appropriate measure or predicator of professionalism, at least for undergraduate medical students.
One of these was based on the high correlation of items within and between the first three blocks of items, which suggested they might be better represented by a single factor representing generalized learning gains, thus yielding a two-factor model.
Furthermore, other work has shown that WM capacity for simple object features, such as colours, is around 4 items [46 50], which suggests that the requirements of the conjunction task in the current study are within normal capacity limits.
Cronbach's α with 17 items was 0.80, which suggests a high degree of rater homogeneity.
In our study, the deceptive items elicited higher mean amplitude than the truthful items did, which suggested that the deceptive process required more cognitive endeavors leading to a longer perceived duration.
In Experiment 1, both appetizing and bland foods were detected faster among nonfood items than vice versa, which suggests that evolution has shaped the attention for effective detection of visual features that signal opportunities for energy intake.
Furthermore, 15 out of 24 items presented threshold disorders, which suggests that the response scale is not adequate and therefore contribute to the misfittings found both in model and item levels.
The internal consistency for these two items was weaker, with α = 0.53, which suggests each item appropriately measures different social influences.
