Congratulations Isabel & Tom!

September 12, 2016—Congratulations on a new three-year grant from the National Science Foundation on Measuring, Mapping, and Modeling Perceptual Expertise; PI is Isabel Gauthier, co-PI is Thomas Palmeri, and Senior Investigators are Sun-Joo Cho from Vanderbilt, Gary Cottrell from UCSD, and Mike Tarr and Deva Ramanan from Carnegie Mellon. This project supports a collaborative interdisciplinary research network that aims to develop measures of individual differences in visual recognition, relate behavioral and neural markers of individual differences, develop models that explain individual differences, and relate models with neural data.


Congratulations, David and Camilla!

September 9, 2016—Study of Mathematically Precocious Youth Discussed in Nature The SMPY (Study of Mathematically Precocious Youth) was the topic of a feature news article published in the journal Nature on September 8th. The SMPY was found by Professor Julian Stanley in 1972, and is now run by Professor David Lubinski and Dean Camilla Benbow. Congratulations to David and Camilla on a fascinating article about an amazing research study.


Congratulations Steve!

September 7, 2016—Steve Hollon has won the 2016 Joseph Zubin award from the Society for Research in Psychopathology (SRP)! The SRP bestows this award each year to one deserving individual for lifetime contributions to the understanding of psychopathology. It was established in 1986 and officially named the Joseph Zubin Award in 1990. It is considered the most prestigious award for psychopathology research.

Congratulations Sohee, Geoff and Leslie!

August 26, 2016—A few of our faculty were highlighted at the 2016 Fall Faculty Assembly. Sohee Park and Geoff Woodman received a Chancelor's research award for their groundbreaking work on using tDCS for improving people with schizophrenia in error detection and control and Leslie Smith was congratulated for her 25 years of service in teaching and undergraduate education at Vanderbilt.

Towards Real-Time Cognitive Model Based Monitoring for Adaptive Decision Support

In applied settings, cognitive models serve a critical role bridging theory and practice, bridging the laboratory and the real world.  There is particularly strong potential for using models as these bridges in the design of adaptive human-computer interfaces to support complex, dynamic decision making. Simultaneously, these dynamic decision-making environments both offer rich behaviors for study and challenge our ability to assess cognitive performance. In this talk, I will argue that leveraging cognitive models for measurement is (1) critical to understanding performance in such complex settings and (2) critical to developing the desired adaptive systems responsive to user performance interpreted through the cognitive models.  I will review initial steps we have taken to advance the use of models as measurement tools, including a new technique for real-time model parameter estimation. I will explore how dynamic multitasking requires potential extensions of discrete decision making models to more continuous decision monitoring while raising questions for how to model task switching. I will show how early modeling of eye-hand coordination on touchscreens indicates how interaction properties shape the dynamics of both movements.  Throughout this talk, I will raise important questions to challenge cognitive modeling research to continue bridging the laboratory and applied settings.

Spatial Release of Masking in Macaques and its Neuronal Correlates

Tones spatially separated from maskers are detected at lower sound levels than those colocalized with maskers (spatial release from masking, SRM). SRM has been well explored in humans but not in animal models. SRM, when measured in azimuth, may index temporal processing. We hypothesized that macaques would show significant SRM in azimuth, similar to humans, and that SRM would be worse after noise induced hearing loss in a manner correlated with ribbon synaptopathy, but not outer hair cell loss. We measured SRM for tones (0.5 – 32 kHz) and synthetic human vowels in normal and hearing impaired macaques for spatial separations between signal and masker of  0Ëš, 45Ëš, or 90Ëš in azimuth. Signal detection thresholds were highest when signal and noise were colocalized and lower when the noise was separated from the tone (SRM), consistent with results in humans. SRM was not observed in macaques with hearing loss at frequencies where synaptopathy was observed, even though masked thresholds were higher than tone thresholds. Neuronal responses measured from the inferior colliculus (IC) simultaneously with behavior showed a strong neuronal correlate of SRM. These results suggest that SRM may be a good test for synaptopathy. Supported by NIH-NIDCD T35DC0008763 and R01 DC011092.

"Structural-Functional Relationships Between Eye Orbital Imaging Biomarkers and Clinical Visual Assessments"


Optic neuritis (ON) is the most common presenting symptom in MS, and in long standing MS, evoked potential studies show evidence of optic nerve involvement in 90% of patients. The post-mortem optic nerve is atrophic in patients with remote ON and to a lesser extent in MS patients without ON. There is currently little understanding of the relationship between disease severity and function with measures of eye and optic nerve morphology and structure. This research investigated this relationship in a cohort of over 800 patients with MS scanned longitudinally. Orbital magnetic resonance imaging (MRI) were retrieved and labeled in 3D using multi-atlas label fusion. Based on the 3D structures, both traditional radiology measures (e.g., Barrett index, volumetric crowding index, optic nerve length) and novel volumetric metrics were computed. Using stepwise regression and random effects models, the associations between imaging-derived structural metrics and clinical metrics of disease stage and severity are investigated.

December 11, 2016 – Documentary and discussion: incarceration and mental health

Physicians for Human Rights would like to invite you to a documentary screening & discussion about mental health and incarceration in America. We will watch "The Released," a Frontline documentary as described below:

"This year, hundreds of thousands of prisoners with serious mental illnesses will be released into communities across America, the largest exodus in the nation’s history. Typically, mentally ill offenders leave prison with a bus ticket, $75 and two weeks worth of medication. Within eighteen months, nearly two-thirds are re-arrested. In this follow-up to the groundbreaking film The New Asylums, FRONTLINE examines what happens to the mentally ill when they leave prison and why they return at such alarming rates."

We hope you'll join us for a night of good discussion! Pizza will be provided for those who RSVP.
