In a passive viewing task (PVT) 36 website screenshots differing in their degree of complexity (operationalized by JPEG file size; correlation with complexity ratings in a preliminary study r=".80) were presented to 48 participants in randomized order.
Finally, in some cases rewards were delivered while subjects were engaged in a passive viewing task, with no behavioral or attentional requirements [36] [37].
The amygdalae responses were found to be less active during an explicit valence rating task than in a passive viewing task [ 20, 32] due to an increased top-down control from the prefrontal cortex.
The last 6 subjects were tested in 8 scanning sessions consisting each of 7 time series: 2 time series for the main experiment, 1 for each cue - shading and texture, 2 time series (1 for shading and 1 for texture cue) in a 1-back matching task (see below), 2 in a passive viewing using the same control stimuli as in the 1-back task, and 1 localizer.
Each of the seven simulations was created in two versions (total = 14): a passive view-only version for condition 2 (Low Embodied) and the manipulable generative version for the two active conditions: conditions 3 (High Embodied) and 4 (High Embodied-Narr).
While this contrasts with previous novel object training studies [e.g., 1] that were able to show neural effects using a passive viewing task in the scanner, an important caveat is that earlier work involved significantly more training on a family of homogenous objects.
In the control experiment, subjects completed a passive viewing paradigm that replicated the main experiment, but subjects did not produce force.
As a second validity check of the emotion evoked by the IAPS images, on a transient basis in the positive block, participants completed a passive viewing task of positive and neutral IAPS images (both those viewed in the AX-CPT and novel images, matched on normed valence and arousal ratings) after the AX-CPT task blocks in the emotion session.
A passive viewing task with dynamic facial expressions was used in a randomized placebo controlled between-subjects design.
This is not a passive viewing of instructional video.
