Are we ovary-acting? All visuospatial abilities may not be equally affected throughout the menstrual cycle.

Department of Psychological Sciences & Neuroscience, Belmont University, Nashville, TN

Visuospatial skills pertain to the ability to conceptualize and comprehend visual representations of objects and the spatial relationships among objects. They are integral for the proper functioning of other cognitive systems such as memory, attention, and reasoning (Kaufman, 2007). Sex hormones are one of many factors reported to affect visuospatial processing, with estrogen specially being associated with poor performance on visuospatial tasks in females (Hausmann, 2000). The current study investigated performance differences on three visuospatial …

Emotion Recognition With Audio, Video, Eeg, And Emg: A Dataset And Baseline Approaches, Jin Chen, Tony Ro, Zhigang Zhu

Publications and Research

This paper describes a new posed multimodal emotional dataset and compares human emotion classification based on four different modalities - audio, video, electromyography (EMG), and electroencephalography (EEG). The results are reported with several baseline approaches using various feature extraction techniques and machine-learning algorithms. First, we collected a dataset from 11 human subjects expressing six basic emotions and one neutral emotion. We then extracted features from each modality using principal component analysis, autoencoder, convolution network, and mel-frequency cepstral coefficient (MFCC), some unique to individual modalities. A number of baseline models have been applied to compare the classification performance in emotion recognition, …

Our subjective visual experiences involve complex interaction between our eyes, our brain, and the surrounding world. It gives us the sense of sight, color, stereopsis, distance, pattern recognition, motor coordination, and more. The increasing ubiquity of gaze-aware technology brings with it the ability to track gaze and pupil measures with varying degrees of fidelity. With this in mind, a review that considers the various gaze measures becomes increasingly relevant, especially considering our ability to make sense of these signals given different spatio-temporal sampling capacities. In this paper, we selectively review prior work on eye movements and pupil measures. We first …
