Serial position analyses revealed that both item types suffered equivalent forgetting across serial positions, but enhancement was evident mostly in the first half of List 2. Experiment 4 used the item-method of directed forgetting and obtained greater directed forgetting for VTs than SPTs.
Cysteine residues were engineered into serial positions along the two helices through the membrane, TM1 and TM2, as well as double mutants in TM1 and TM2, and the extent of crosslinking determined to characterize the organization of the TM domain.
The probe ("X") was presented 10 times at each of the possible serial positions, yielding 90 probe-present trials.
These results could indicate that bees may evaluate the 4 serial positions not only independently, but also to some degree as a pattern or a configural unit.
a) Similar context conditions: Although bees may experience longer flight distances in the tunnel the same location in the navigational space of the bee may not allow the bee to associate different serial positions of "landmarks" to different flight directions.
This pseudo-random order was built in such a way that each condition appears at all serial positions within a run and two conditions appeared once or twice in immediate succession to prevent confounding order effects.
