DOI: 10.1007/s10071-017-1147-x
Abstract: The purpose of the present study was to examine whether rhesus monkeys remember information about their own agency—along with spatial, temporal and contextual properties—from a previously experienced event. In Experiment 1, rhesus monkeys (n = 4) used… read more here.

DOI: 10.1007/s10071-019-01246-5
Abstract: Some nonhuman species demonstrate metamemory, the ability to monitor and control memory. Here, we identify memory signals that control metamemory judgments in rhesus monkeys by directly comparing performance in two metamemory paradigms while holding the… read more here.

DOI: 10.1007/s10071-019-01263-4
Abstract: Humans are characterized by complex social cognitive abilities that emerge early in development. Comparative studies of nonhuman primates can illuminate the evolutionary history of these social capacities. We examined the cognitive skills that rhesus monkeys… read more here.

DOI: 10.1016/j.pbb.2017.03.008
Abstract: ABSTRACT Benzphetamine is a Schedule III anorectic agent that is a prodrug for d‐amphetamine and d‐methamphetamine and may have utility as an “agonist” medication for cocaine use disorder treatment. This study evaluated the pharmacokinetic‐pharmacodynamic profile… read more here.

DOI: 10.1016/j.visres.2020.07.004
Abstract: Studies in chickens suggest low intensity ambient lighting causes myopia. The purpose of this experiment was to examine the effects of low intensity ambient lighting (dim light) on normal refractive development in macaque monkeys. Seven… read more here.

DOI: 10.1016/j.visres.2020.08.003
Abstract: Dual-focus lenses that impose simultaneous competing myopic defocus over the entire visual field produce axial hyperopic shifts in refractive error. The purpose of this study was to characterize the effects of eccentricity on the ability… read more here.
