Fisman and Miguel sought to test the opposite hypothesis: who, in the absence of any legal penalty — the diplomats enjoyed immunity and would never be punished for failure to pay parking tickets — would pay, rather than abuse this prerogative?
We thus measured basal levels of DA, NE, 5-HT, and ACh, as well as their metabolites, in both groups of mice and tested the hypothesis that the opposite behavioral effects after global NE depletion could be explained by constitutive biochemical differences.
But new targets are being tested with the opposite effect in mind, said Paul J. Browne, a police spokesman.
Experiment 3 demonstrated that prior exposure to response-contingent shock on one hindleg facilitated acquisition of the response when subjects were later tested on the opposite leg.
But few studies have tested whether the opposite holds true for males--whether they're naturally promiscuous when sperm are plentiful and parental investment low.
As the Su var)2-5 05 embryoshowow a decrease in H3K27me3, we tested whether the opposite mark promoted by the trxG, H3K4me3, was also affected.
Moreover, this aftereffect is able to transfer across orientations, although the effect is notably smaller when tested in the opposite orientation (Watson & Clifford, 2003; Webster & MacLin, 1999).
While these two studies examined the ability of females to vocally recognize female kin, we are aware of only one study that tested the ability to vocally distinguish opposite-sex relatives.
