It can be used in contexts related to experiments, studies, or tests where results are being discussed based on one instance or occurrence.
Example: "The results were significant at a single trial, indicating a potential breakthrough in the research."
Alternatives: "in one trial" or "during a single test".

Blue and yellow symbols indicate the mean firing level over a single trial at the corresponding value of U C and U H, respectively.
Phase similarity is calculated as the angular difference between a single trial phase at a given time and frequency (here: shortly after S1 in the theta frequency range) and the circular mean phase angle across trials.
Like rats trained on reversal tasks, the monkeys eventually solve each new problem after a single trial, choosing at random on the first trial with each new pair of stimuli but thereafter selecting with essentially perfect accuracy.

For the amplitude of EEG oscillatory activity to significantly predict MEP size on a single trial basis, at least 10 consecutive correlation coefficients [ 17] of the real data need to be either significantly higher than the surrogate upper threshold correlation coefficients or significantly lower than the surrogate lower threshold correlation coefficients (P < 0.025, one-tailed).
