A Behavioral Study on the Adult Marmoset Interference Control in Spatial Working Memory
… jacchus) is an ideal non-human animal model for studying WM disorders. Previous studies of marmoset WM have used a touch-screen self-ordered sequencing task (SOST), which resembles an n-back paradigm and targets updating processes in internal interference control. However, the training time for …

Behavioral Study of the Red Lechwe antelope (Kobus leche leche) on Double D ranch, Bastrop County, Texas
A behavioral study on the red lechwe antelope (Kobus leche leche) was conducted at Double D Ranch, Bastrop County, Texas between July 1997 and August 1998. Habitat use, as well as the major behaviors, feeding, resting, and mating, of lechwe introduced in Texas were compared to that described for …

Estudos em meio poroso heterogêneo sujeito a bombeamentos periódicos
The purpose of this work is the behavioral study of a heterogeneous porous media, when it suffers an unsteady periodic pumping. For this, we built a special equipment and moulded an artificial porous media to which was applied a steady contour condition upstream and the unsteady pumping was made …

Why Did You Post That GIF? Understanding Relationship between User Identity and Self Expression through GIFs on Social Media
… through the lens of GIFs they use. In this study, we explore how do Twitter users express their gender and racial identities through that of characters in gifs. We conducted a behavioral study (n=398) to simulate a series of tweeting and gif picking scenario and we found that gender and race …

Filters, Neighbors, and Triangles: A Behaviorally and Electrophysiologically Informed Perspective on Visual Word Recognition
Two Event-Related Potential (ERP) studies and one behavioral study are presented in service of a single goal: to evaluate current prevalent computational models of visual word recognition. Specifically, the functionally homogenous cooperative division of labor model (Triangle) and the full family …

Effects of Trout Introduction on Community Assemblage and Behavior of Native Fish in the Missouri Ozarks
… less variable water temperature. Results of the behavioral study indicate that trout introduction had an effect on the flight initiation distance, a proxy of wariness, of rainbow darters, Etheostoma caeruleum, and orange throat darters, Etheostoma spectabile. The increased wariness observed in …

Reward and prediction errors in Bayesian sensorimotor control
… and current sensory information. The present behavioral study addressed the contributions of tonic and phasic dopamine in a Bayesian decision-making task by alternating reward magnitude and inferring reward prediction errors. Twenty-four participants were asked to indicate the position of a …

Carcass Feeding for Captive Vultures: Testing Assumptions about Zoos and Effects on Birds and Visitors
… scavengers like vultures, a lack of activity and behavioral opportunities could be a welfare problem in captivity; providing them with a more complex food item might mitigate this. The goal of this study was, thus, to assess the frequency of carcass feeding for vultures in North American zoos, …
