To explore this, a within-subject counterbalanced design was used.
In a within-subject counterbalanced design, participants learned a list of word pairs after a mood induction procedure (MIP), then slept or stayed awake during the post-learning night.
Experiment 2 (n=10) utilized a within-subject counterbalanced design to manipulate food deprivation and hunger levels to determine if food deprivation increased the reinforcing value of snack food as measured by the questionnaire to provide an index of validity of the questionnaire.
The present study employed a within-subjects, counterbalanced design.
A within-subjects, counterbalanced design was used so that each rat received both saline and sumatriptan injections.

In a within subjects counterbalanced design, we compared the effect of 7 19 nights with a late bedtime (01 00) versus 7 19 nights with an early bedtime (22 00) on the human dim light melatonin rhythm.
In a within-subjects counterbalanced design, 42 hungry participants completed two pizza-cue exposures in a single experimental session during which their expectation of consuming the pizza was manipulated (i.e., expectancy of eating imminently vs. no eating expectancy).
Measurements were taken from 29 privately-owned dogs (14 males, 15 females), ranging in age and breed, in their own home and in a boarding kennel environment, following a within-subjects, counterbalanced design.
We used ATD to temporarily lower plasma and brain 5-HT levels in a randomized, double-blind, placebo-controlled, within-subjects, counterbalanced design, as previously described (63) (Supplement 1).
These trials were divided into four blocks of three trials representing Conditions 1, 2, and 3; the order of conditions was fixed for one subject but counterbalanced across subjects.
