Pictures and sounds of objects were presented simultaneously in two levels of recognisability, thus manipulating the amount of cross-modal competition.
In P1, each diet was presented solely for five days to facilitate pre- and post-ingestive associations; in P2 a two-choice test was conducted with four diet combinations (contrasts) over three days; and in P3 the four diets were presented simultaneously in a checkerboard fashion over a 5-day period.
In some of these studies, the two numerosities are presented in different modalities (e.g., one in the visual, and one in the auditory, modality), or their items are presented simultaneously in one numerosity and sequentially in the other [32] [35].
All 10 stimuli (letters or numbers) were presented simultaneously in each trial.
In each phase, first time stimuli were presented simultaneously, in order to allow familiarization with the material.
Stimuli were one-dimensional Gaussian white noise fields with a two-octave frequency filter and were presented simultaneously in a triangular array.
Each trial began with an ×', presented for 300 ms and followed by a blank screen, which lasted for 200 ms. Then, both operands were presented simultaneously in Arabic digits for 100 ms, separated by two blank spaces.
In contrast, when the color and word are presented simultaneously in a manual modality, the faster and more direct color mapping allows for a response to be selected before the word is fully active, creating smaller interference.
In the priming task, two Navon stimuli were presented simultaneously, one in the left and one in the right visual field, each with the most medial edge 0.25° from fixation.
However, which proteins need to be present simultaneously in order to perform a given function is frequently unknown.
