At several occasions other members of the research team (KS, CS) asked critical questions as regards the categorization of the concepts, and this led to some adaptations in the final ordering and presentation of the categories and sub categories and consequently the results.
However, we did not give any instructions to regulate, subjects did not report that they did, and randomized order and short presentation time of the pictures make it unlikely that they were able to.
Finally, to reduce the inherent bias in repeated testing of a skill, we randomized the order and subject of presentation of students.
Both order and side of presentation were randomised.
Clarke's much trumpeted "rehabilitation revolution" barely got a mention during the hour and a half law and order presentation at the conference.
The booklet form of the decision aid was finished first, and provided the text and order of presentation that were duplicated in the audiotape and Internet versions.
A mixed linear model with 'type of playback sound', 'oestrus state' and 'presentation order' as fixed factors and subject as a random factor revealed a significant difference for presentation order (F1,46 = 7.2, p = 0.01) and a significant interaction between the type of playback sound and presentation order (F2,46 = 3.9, p = 0.027).
Lists were presented auditorily at a rate of 1 word every 2500 ms, and presentation order of the lists was random.
Within each study, the order of air/UFP exposure was randomized, and the randomization was blocked by order of presentation and sex, so that equal numbers of men and women inhaled air first or UFPs first.
The context was blocked in separate sessions to avoid carry-over effects from one condition to another one (sessions were run at about 2 weeks distance, and presentation order was counterbalanced across subjects, n = 7).
