Given the attentional and motivational saliency of infant faces, triggered by a set of perceptual baby schema features, other‐ethnicity infant faces may overcome the processing differences associated with the other‐race effect (ORE). Using an attentional bias paradigm, we found that while there was a same‐ethnicity attentional bias for adult faces, there was no difference in attention to same‐ and other‐ethnicity infant faces, suggesting that other‐ethnicity infant faces are equally salient and not subject to the same bias as other‐ethnicity adult faces. To directly measure the ORE, we used a recognition memory test to measure differences between same‐ and other‐ethnicity infant and adult faces. Regardless of age, same‐ethnicity faces were better remembered than other‐ethnicity faces. Further, regardless of ethnicity, adult faces were better remembered than infant faces, a finding consistent with an Other Age Effect. Taken together, these experiments suggest that the saliency of baby schema does not fully overcome the social or perceptual factors leading to the ORE.
Past, present, and future actions must be regulated online to produce sequences of actions, but the regulation process is not well understood because of measurement limitations. We provide the first direct tests of the parallel action regulation hypothesis during sequencing in humans. We used transcranial magnetic stimulation to probe the level of excitation for flexion of the right index finger during typing. Motor evoked potentials (MEPs) were recorded at the onset of typing 5-letter words and nonwords. A single letter typed by the right index finger varied across letter positions 1 to 5. MEP amplitude was largest for the upcoming action in the second position and decreased monotonically across future serial positions, suggesting a serial inhibition process regulates all future actions in parallel during sequencing. This is the most direct human evidence to date corroborating models of sequence production that assume parallel regulation of actions. (PsycINFO Database Record
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
