Tatiana Aloi Emmanouil, Assistant Professor of Psychology, investigates the cognitive and neural mechanisms of vision in humans. Her work spans the fields of visual attention, awareness and memory as it attempts to understand how we process, store and experience the complex visual world that surrounds us. Professor Emmanouil received a BA in Psychology from UC Berkeley, a PhD in Psychology and Neuroscience from Princeton University under the tutelage of Anne Treisman, and worked as a postdoc at CUNY with Tony Ro. Her work, uses behavioral as well as neuroimaging methods such as functional magnetic resonance imaging, transcranial magnetic stimulation, and electroencelphalography.

Research Currently in Progess

Papadimitriou, C., Vempala, S., Emmanouil, T., & Ro, T.(n.d.). Neural computation by assemblies of neurons. In Progress.

This is a collaborative project between CUNY, Columbia and Georgia Tech, combining expertise from computer science and cognitive neuroscience. The goal is to develop and test a new theory of neural computation by assemblies of neurons. I am working closely with Tony Ro from he graduate center of CUNY on empirically testing the theory through analysis of electrocorticography (ECoG) data and through novel EEG and fMRI experiments. The EEG experiments are now in the piloting phase.

Emmanouil, T.(n.d.). Neural correlates of ensemble perception. In Progress.

This project investigates where and when ensemble computations are performed in the brain. One experiment using electroencephalography (EEG) is completed and recently published. Follow-up EEG experiments, as well as novel functional magnetic resonance imaging (fMRI) experiments are planned under the funded NIH R15 protocol,

Magen, H., & Emmanouil, T.(n.d.). Self initiated memory for space and objects. In Progress.

This is a project I have been working on with Hagit Magen from Hebrew University. The first two papers looked at self-initated working memory representations for spatial sequences and for spatial locations. A third project looks at the role of space for self initiated memory visual working memory. The first three papers have been accepted,. A fourth project examines self Initiated memory for different sizes in an ensemble. The data for the fourth paper have been collected and the manuscript is in preparation.

Tsering, M., & Emmanouil, T.(n.d.). The influence of affect on ensemble perception. In Progress.

This project in collaboration with MS student Migmar Tsering examines the role of positive affect on statistical representations to test whether positive affect influences distributed attention in the similar way it influences focused attention as revealed by performance in tasks such as the attentional blink. Data collection in the lab was paused due to the COVID-19 pandemic. Data collection was completed onlin eand Migmar is writing his thesis.

Moore, C., Epstein, M., & Emmanouil, T.(n.d.). The role of working memory load on ensemble perception. In Progress.

This project, in collaboration with MS student Clark Moore, examines the effects of working memory load on the timing and neural representation of ensemble perception. EEG data collection was started by it was paused due to COVID-19 pandemic. We collected behavioral data online measuring processing time using reaction times as opposed to ERPs. Clark completed his masters thesis. For publication we would need additional EEG data, which will be collected once in-person research resumes.

Mandelbaum, E., & Emmanouil, T.(n.d.). Causation and the Perception/Cognition Border. In Progress.

An empirical project investigating whether certain representations become conceptualized by vision without the aid of cognition.

Emmanouil, T., Quilty-Dunn, J., Garcia, R., & Young, S.(n.d.). Ensemble coding of facial trustworthiness and dominance. In Progress.

This project investigates whether people can perceive average trustworthiness and dominance in a group of faces. We have collected data for four experiments, showing that people accurately judge ensemble dominance and trustworthiness for upright and inverted faces. We are currently conducting further experiments to shed light on the implications of this type of judgment of real world decisions and social interactions.

Emmanouil, T., Dana, J., & Jerskey, G.(n.d.). Ensemble coding of symmetry. In Progress.

This project investigates ensemble coding for a Gestalt property, symmetry. Participants are presented with displays with a mix of symmetrical and asymmetrical objects and are asked how symmetrical the group is on average. The data was analyzed and presented in the MS thesis of Gene Jerskey. For publication we have decided to collect more data online.

Mandelbaum, E., & Emmanouil, T.(n.d.). Investigating Causal Perception. In Progress.

A project attempting to show that automatic illusory causal perception happens in three-dimensional environments, with cues that show that contact is impossible.

Emmanouil, T., Garcia, R., & Lee, J. E.(n.d.). Iterative ensemble perception. In Progress.

This study investigates whether statistical properties are dynamically updated over time. One project will examine whether the visual system extracts statistical estimates for partially occluded objects and whether these estimates are updated to correct for occlusion over time. Preliminary results show that ensemble perception of occluded objects is possible. The results will shed light on the timing of ensemble perception. In person data collection was paused due to COVID-19 pandemic. Data collection will resume on line.
