Adverse publicity has already hit response rates to sweepstakes, which people in the industry say are down by around 60%.
A nose-poke in the lit aperture during the stimulus plus a 2 s limited hold period resulted in a correct (Hit) response being registered and a reward being delivered in the magazine.
Dependent on the player's response (hit or stand), the dealer started to take another card 300 ms after the player decided to stand (stand response), and 2000 ms after the player's hit (hit response).
The mean amplitude of BF bursting and EEG/LFP in the five quintiles were then normalized by their respective average amplitudes in hit trials, such that the average hit response amplitude corresponded to 100%.
And very quickly, the Obama campaign came out with a hard hitting response, pointing to a series of education accomplishments made by Obama, and calling McCain "perverse" for the latest attack.
You hit reply, type your response and then switch to the Sunrise keyboard.
Among them, 44 genes are hit for response to stress, 40 for response to biotic stimulus, 37 for response to external stimulus, 33 for response to abiotic stimulus, and 10 for response to endogenous stimulus.
For the CVS task, the better performance associated with longer display presentation was mainly due to a decrease in FALSE ALARM rate (RM ANOVA with FALSE ALARM rate in function of CVS items display duration condition: p<0.0001, F = 52.74) rather than to an increase in HIT responses (RM ANOVA: p = 0.35, F = 1.13).
A similar interaction was observed when the confidence ratings were analysed for correct rejections only (i.e. identifying an 'old' item as old; (F 1,23) = 12.21, p<.05, η2 = .35) and a trend in the same direction was apparent in the case of hit responses (F 1,23) = 3.65, p = .069).069
For HIT responses, the probability to detect a letter was higher when flashed inside the target (post-hoc: all p<0.0001) and, to a lesser extent, inside level 3 distractors, i.e. the most resembling distractors (post-hoc: p = 0.03, Fig. 4A).
Target detection sensitivity (d′) and mean reaction time for hit responses (RT) were calculated for each of the 4 experimental conditions and then entered into 2 × 2 repeated measurement analyses of variance (ANOVAs) (stimulus timing × presence of auditory tone).
