Fronto-central and central clusters showed a graded effect, with targets hits the most positive and related lure correct rejections least positive (target hits > related lure false alarms > related lure correction rejections(p values < 0.05).
For 600 700 ms, target hits were significantly more positive than related lure false alarms (p < 0.001), but only numerically more positive than related lure correct rejections (p > 0.51).
We then analyzed veridical memory for "true" words (words that were presented previously) and false memories (false positives for critical "lure").
The positive effect of the lure on estimates of density was significant for 33% of taxa, including: ambush predators (Trachinus draco), fast moving cruise-chase predators (Sparidae), predators chasing prey from a hidden waiting position (Coris julis and Serranidae) or from a position of camouflaging against bare sand (Gobiidae).
They contrasted the pattern separation performance of 20 young adults with 20 adults aged over 65 years, finding that the older adults were more likely to commit false positive errors and identify lure stimuli as old.
With respect to event-related potentials we find significant differences for consistent compared to inconsistent lures in the N400 (increased negativity) and Late Positive Component (reduced positivity).
fMRI activity in the hippocampus was found to distinguish between correctly identified old stimuli, correctly rejected similar lure stimuli, and false positive responses to similar lures.
Four treatments, nilgai offal a natural odor lure was used as the positive control; and compared to three artificial odors; screw worm lure, volatile fatty acids, citronella oil.
It rates Wells Fargo as "AAA" for depositors a positive sign that could help the bank lure new customers rattled by the huge losses being wracked up by other big lenders.
Instead, lured by three years of positive returns in bond markets, they are switching to fixed-income securities.
