 This bias has been proposed to have a critical evolutionarily adaptive function, becaexercising the more(prenominal) than rapidly a danger can be recognized, the more likely an organism will be able to relocation appropriately. However, considerable behavioral research has found that positive stimuli showed shorter response times and lower error rates than negative ones. In other words, peopl e responded faster to positive stimuli than ! they did to negative ones (Jiang, Yang, & Liu, 2007; Rossell & Nobre, 2004;Ventura, Rothermund, & Bak, 2000). The reason for these conflicting results may rest in the different characteristics of research tasks. First, there are differences in the research methods. Studies on negativity bias have tended to example advanced research tools that were focused on the neurophysiologic activity of the sense in emotional processes (Delplanque et...If you want to get a well(p) essay, instal it on our website: OrderCustomPaper.com
