Contrast Negation Differentiates Visual Pathways Underlying Dynamic And Invariant Facial Processing, Pamela M. Pallett, Ming Meng
Contrast Negation Differentiates Visual Pathways Underlying Dynamic And Invariant Facial Processing, Pamela M. Pallett, Ming Meng
Dartmouth Scholarship
Abstract Bruce and Young (1986) proposed a model for face processing that begins with structural encoding, followed by a split into two processing streams: one for the dynamic aspects of the face (e.g., facial expressions of emotion) and the other for the invariant aspects of the face (e.g., gender, identity). Yet how this is accomplished remains unclear. Here, we took a psychophysical approach using contrast negation to test the Bruce and Young model. Previous research suggests that contrast negation impairs processing of invariant features (e.g., gender) but not dynamic features (e.g., expression). In our first experiment, participants discriminated differences in …
The Composite Effect For Inverted Faces Is Reliable At Large Sample Sizes And Requires The Basic Face Configuration, Tirta Susilo, Constantin Rezlescu, Bradley Duchaine
The Composite Effect For Inverted Faces Is Reliable At Large Sample Sizes And Requires The Basic Face Configuration, Tirta Susilo, Constantin Rezlescu, Bradley Duchaine
Dartmouth Scholarship
Abstract The absence of the face composite effect (FCE) for inverted faces is often considered evidence that holistic processing operates only on upright faces. However, such absence might be explained by power issues: Most studies that have failed to find the inverted FCE tested 24 participants or less. Here we find that the inverted FCE exists reliably when we tested at least 60 participants. The inverted FCE was ∼ 18% the size of the upright FCE, and it was unaffected by testing order: It did not matter whether participants did the upright condition first (Experiment 1, n = 64) or …

The management of recurrent pregnancy loss (RPL) still remains a great challenge, and women with polycystic ovarian syndrome (PCOS) are at a greater risk for spontaneous abortion. Treatment with low-molecular-weight heparin (LMWH) has become an accepted treatment option for women with RPL; however, the subgroup of women, who are likely to respond to LMWH, has not been precisely identified. The present study evaluated the efficacy of LMWH with reference to PCOS and associated metabolic phenotypes including hyperhomocysteinemia (HHcy), insulin resistance (IR) and obesity. This prospective observational study was conducted at Institute of Reproductive Medicine, Kolkata, India. A total of 967 …

The two compositionally distinct extracellular cochlear fluids, endolymph and perilymph, are separated by tight junctions that outline the scala media and reticular lamina. Mutations in TRIC (also known as MARVELD2), which encodes a tricellular tight junction protein known as tricellulin, lead to nonsyndromic hearing loss (DFNB49). We generated a knockin mouse that carries a mutation orthologous to the TRIC coding mutation linked to DFNB49 hearing loss in humans. Tricellulin was absent from the tricellular junctions in the inner ear epithelia of the mutant animals, which developed rapidly progressing hearing loss accompanied by loss of mechanosensory cochlear hair cells, while …

Spinal cord injury (SCI) and other neurological disorders involve complex biological and functional changes. Well-characterized preclinical models provide a powerful tool for understanding mechanisms of disease; however managing information produced by experimental models represents a significant challenge for translating findings across research projects and presents a substantial hurdle for translation of novel therapies to humans. In the present work we demonstrate a novel 'syndromic' information-processing approach for capitalizing on heterogeneous data from diverse preclinical models of SCI to discover translational outcomes for therapeutic testing. We first built a large, detailed repository of preclinical outcome data from 10 years of basic …
The Effects Of Heading On Neurocognitive Function In Female Collegiate Soccer Players During An Entire Soccer Season, Sarah E. Nonaka, Scott Mclean, Jimmy Smith
The Effects Of Heading On Neurocognitive Function In Female Collegiate Soccer Players During An Entire Soccer Season, Sarah E. Nonaka, Scott Mclean, Jimmy Smith
International Journal of Exercise Science: Conference Proceedings
Recently, much debate has occurred regarding the effects of repeated heading by soccer players on their neurocognitive function. PURPOSE: To determine the effects of heading on neurocognitive function in female collegiate soccer players during an entire soccer season. METHODS: Twenty-four members of the 2012 Southwestern University Women’s Soccer team completed the ImPACT test during preseason and postseason, and self-reported the number of headers for the week immediately prior to each testing session. Amount of playing time for each player was determined from records obtained from the Southwestern University Athletics Department. The six composite scores and the cognitive efficiency index from …
