SMP Spotlight

Katie Gluskin and Jeff Haus present their SMP
Katie Gluskin and Jeff Haus, "Entorhinal Cortex Lesions, Habituation, and Latent Inhibition," 2013. Gluskin and Haus, the 2013 co-winners of the Neuroscience Award, infused a neurotoxin into the entorhinal cortex of rats to induce a lesion, and measured the resulting habituation and latent inhibition behavior within a fear conditioning paradigm.


Mirenzi, Aaron (2011).  Analyzing the gender aftereffect in biological motion : the effects of adaptation to static and dynamic stimuli. (Mentor: E. Hiris)


Biological Motion stimuli present human form and motion through points of light placed on major joints of the human body. These point light walkers (PLWs), though minimal, present enough information for accurate gender perception.  It has been shown that adapting to a hyper sexual PLW will bias the perception of a subsequent PLW as being the opposite gender (Troje, Sadr, Geyer, & Nakayama, 2006). Aftereffect research uses the assumption that the aftereffect is caused by adaptation to a particular aspect of the stimulus. In the case of biological motion perception, low level motions are combined to create a global form, which is then placed in a gender category. Thus, adaptation could be occurring to the motions of the stimulus, the form of the stimulus, or to gender as a concept. This paper addresses which physical aspects of biological motion are adapted to in the gender aftereffect. Experiment 1 used full body images, which evoked gender as a concept, as adaptation stimuli, however, these images were unable to cause an gender aftereffect in the perception of a PLW, suggesting that the aftereffect is perceptual, not conceptual. Experiment 2 used PLWs reduced to four hip and shoulder points as adaptation stimuli. Despite research showing the critical nature of hip and shoulder points for gender perception, adaptation to these points alone did not cause a gender aftereffect in a complete PLW. Experiment 3 used static PLWs to test whether the form of the stimulus was the adaptive property of the stimulus. Contrary to several studies showing the importance of motion in gender perception, we found that adaptation to a non-moving PLW created an aftereffect similar to when a dynamic PLW was adapted to. We conclude that in the gender aftereffect in biological motion, the form of the stimulus is the adaptive property.  Experiment 3 suggests that form processing is critical for gender perception in humans, even in displays which highlight human motion, and minimize human form.
