Reagent and procedural blanks were measured in parallel to sample treatment using identical procedures.
What was probably more surprising to most readers was the huge price differentials for identical procedures — not only across the United States, but even within American cities, where prices for a given procedure can vary tenfold.
However, varying results have been reported on identical procedures in different animal species.
Identical procedures were completed in the control trial except no exercise was performed.
In the distraction condition, identical procedures were followed, but during heat-capsaicin pain, subjects played a series of video games.
Although the studies with trainees and with experienced officers were preregistered separately, we describe their methods and results jointly given that they used identical procedures.
At the next visit, identical procedures were repeated.
Next subjects completed a reverse category verification task with identical procedures with the exception that the label and the image switched positions.
This led to a second study, which followed identical procedures but incorporated a revised stimulus set with variations to color and orientation.
Previous studies have used identical procedures to scan chimpanzees and have revealed significant and consistent patterns of PET activation (Taglialatela et al., 2008; Taglialatela et al., 2009).
Previous studies have used nearly identical procedures to scan other non-human primate species and have revealed significant and consistent patterns of PET activation [17], [20], [21], [22], [23].
