The key manipulation concerned the amount of reading versus spelling practice a given item received.
Recall that the results from Experiment 1 suggested a relationship between the correct detection and location of image manipulations and the amount of disruption the manipulations had caused to the underlying structure of the pixels.
These studies measured sensitivity to location indirectly through the effect of image manipulations on the amount of adaptation.
Logan and colleagues [ 16] described how manipulation of the amounts of transfer, packaging or envelope plasmids did not alter the specific activity (TU/pg p24) but rather influenced the vector concentration in the supernatant (TU/ml and pg p24/ml).
Comparisons of the Stroop effect (incongruent minus congruent) may seem more appropriate; however, as SOA manipulation also affects the amount of facilitation (e.g. increased facilitation in the –400 ms SOA), interpretations of the Stroop effects are just as difficult.
Prior to the critical events, using a between-participant design, 75 drivers were exposed to various screen manipulations that varied the amount of available visual information from the road environment and automation state, which aimed to take them progressively further 'out-of-the-loop' (OoTL).
Interestingly, and perhaps similar to the effects of sleep deprivation, these manipulations did increase the amount of time per cycle spent in the deactivated state.
Thus far there is no standard way to compare across manipulations that controls for the amount and type of information provided by each component image.
The current study tests this assumption by implementing manipulations designed to vary the amount of prime-induced activation in three experiments.
To understand more about people's ability to identify image manipulations, we examined how the amount of change in a photo affects people's accuracy in the detection and location tasks.
