Age slowing down in detection and visual discrimination under varying presentation times
[EN] The reaction time has been described as a measure of perception, decision making, and other cognitive processes. The aim of this work is to examine agerelated changes in executive functions in terms of demand load under varying presentation times. Two tasks were employed where a signal detection and a discrimination task were performed by young and older university students. Furthermore, a characterization of the response time distribution by an exGaussian fit was carried out. The results indicated that the older participants were slower than the younger ones in signal detection and discrimination. Moreover, the differences between both processes for the older participants were higher,…
Diferències entre sexes en la resposta cardiovascular, hormonal i psicològica a una competició: Variables moduladores i facilitadors de la victòria
Competition is a social interaction where there is a confrontation between individuals or groups to achieve an objective. In our society competition is present transversally, with consequences for individuals. Therefore, competition is considered a social stressor able to elicit important psychobiological responses. From an evolutionary perspective, it has been suggested that, against stress situations, men would be more likely to fight-and-flight, while women would be more likely to tend-and-befriend strategies. Consequently, different psychobiological response to competition can be described depending on sex. A large proportion of studies on competition were based on the biosocial status …
