Introduction
I’m currently working as a research assistant at the Instituto de Neuroetología in Veracruz, Mexico. My research interests are related with cognition and behavior of animals, with a special interest in memory, perception and prosocial behavior.

Temporal Weighting Rule (TWR) is a mathematical model used to predict foraging decisions based firstly on recency and secondly on the quality of a patch (amount of food). The objective of this study was to investigate whether those variables modulate the decisions of spider monkeys (Ateles geoffroyi) using a foraging task. Sixteen adult individuals...
One experiment explored the impacts of familiarity between female rats on the pro-social behavior. We trained pairs of Wistar rats in the Pro-social Choice Task. All pairs of rats had an actor and a partner rat that were placed within a double T-maze. Throughout the sessions, actors decided between two options only differing in the food delivered t...
Recently, several authors have reported evidence of helping behavior in rats. However, the mechanisms underlying such behavior are unclear. Two experiments with Wistar rats used the task developed by Sato et al. (2015) to assess whether social enhancement affects the helping response. Experiment 1 tested whether rats placed in a dry compartment adj...
The forgetting curve is a phenomenon in which animals fail to retrieve information about an event as time passes. We tested this effect in spider monkeys (Ateles geoffroyi) in a task where they had to retrieve a reward hidden in a container after a delay. We combined different delays (0, 5, 10, 20, and 30 s) and different numbers of containers in w...
Recognition memory is an ability that allows animals to respond differentially to stimuli, individuals, or situations experienced in the past and plays an important role in foraging and social behavior. We tested the ability of black-handed spider monkeys (Ateles geoffroyi) to remember and recognize visual stimuli that belong to 6 categories. Seven...
Tannins are a chemical defense mechanism of plants consumed by herbivores. Variations in salivary physicochemical characteristics such as pH, total protein concentration (TP), and presence of proline-rich proteins (PRPs) in animals have been reported as a mechanism to protect the oral cavity when consuming food with variations in pH and tannins. Va...
There is extensive knowledge about the visual system and the implications of the evolution of trichromatic color vision in howler monkeys (genus Alouatta) related to food selection; however, information about the other sensory systems is limited. In this study we assessed the use of touch, sniffing, and taste in fruit evaluation by 20 adult mantled...
La memoria es un proceso donde los animales pueden mantener información del pasado para usarla en el futuro. En los estudios de esta habilidad, los primates han sido ampliamente usados, sin embargo, muchas especies no han sido estudiadas, lo que abre la posibilidad de extender nuestra compresión de la memoria a otras especies. El presente trabajo t...
The embodied theory of tooling predicts that individuals accommodate their actions to manage the degrees of freedom (DoFs) in the body-plus-object system when using a grasped object as a tool. We tested predictions from this theory by studying how tufted capuchin monkeys (Sapajus spp.) and humans (Homo sapiens) used a hoe to retrieve a token. The h...
Objective
Reproduction entails several challenges to primate females, among which energetic costs are remarkable at certain stages of the reproductive cycle. Still, females may use behavioral and physiological strategies to cope with those challenges. We had previously reported covariation between female energetic condition through the reproductive...
La empatía es una respuesta afectiva que permite establecer relaciones saludables, generando una mejor convivencia entre los individuos, por ello, es importante contar con instrumentos válidos y confiables para medir dicho constructo. El objetivo del presente trabajo fue la adaptación y traducción de una escala de empatía para niños. La escala cuen...
La empatía se define coloquialmente como la capacidad de ponerse en los zapatos del otro, lo que implica una capacidad de entender los estados emocionales de los congéneres. Durante mucho tiempo esta característica nos pareció una habilidad exclusiva de los humanos, sin embargo investigaciones recientes nos han demostrado que los roedores podría se...
Food intake (i.e., the amount of food consumed by an individual) is a crucial measure for studying feeding behavior, but its measurement requires high visibility of individuals and long recording sessions, which are often difficult to accomplish under field conditions. As a consequence, studies on the feeding behavior of primates typically do not e...
Questions
Question (1)
Hi everybody.
I ran an experiment on memory and calculated the percentage of hits as usually reported in the literature. However, the reviewer asked me to transform my hits into d-prime values. I was able to calculate the d-prime values using the psyphy library in R. But, in my original analysis, I calculated the percentage of hits for each individual, then the average value and the confidence interval of the mean. My question is if I can calculate the mean and the confidence intervals of the d-prime values of my individuals, or if I have to calculate the d-prime value for all the subjects? Do you know if there is a measure of dispersion for the d-prime values?
Thanks for your help
