Sex differences in the psychophysiological response to an intergroup conflict.
2018
Abstract Conflict induces psychophysiological responses, but less is known about responses to intergroup conflict. Intergroup relationships activate social processes, adding complexity to people’s physiological responses. This study analyzes the psychophysiological responses to intergroup conflict considering sex differences. Thus, 150 young people were distributed in 50 groups in two conditions (conflict vs. non-conflict). Conflict was created in the interaction between two groups (three people each) in the laboratory. Their responses were compared to a control group. Mood, heart rate variability, cortisol, and testosterone were measured. Results showed that intergroup conflict induced a l…

El uso de substancias químicas en agricultura y en el hogar para combatir una gran variedad de plagas ha sido generalizado durante todo el siglo pasado, ya que de lo contrario estas plagas menguarían la producción de las cosechas como fuente de alimento. Sin embargo estos beneficios vienen asociados con una serie de perjuicios ya no sólo a nivel de ecosistemas (pérdida de diversidad) sino que conllevan consecuencias para la salud humana. Debido a que la mayoría de los pesticidas actúan sobre el sistema nervioso de los insectos y los procesos neuroquímicos son similares a los del sistema nervioso de humanos, los hace especialmente peligrosos por su neurotoxicidad. En los últimos años se ha o…
Stress effects on cognitive function in healthy adults
2015
In our lives, we are constantly exposed to different sources of stress, specifically psychological or social. Our reaction to stress is an adaptive response due to its role in facilitating survival. However, stress can also have immediate and delayed damaging consequences for health, and it is considered one of the most significant health problems of the 21st century, according to the World Health Organization (2001). The impact of stress extends to most of the physiological systems (i.e. cardiovascular, digestive, immune, neuroendocrine or nervous), resulting in numerous diseases. Cognitive problems stand out among the stress effects related to the nervous system. Given the large impact th…
