The relationship between counterfactual thinking and emotional reactions to event outcomes: Does one account fit all?

By enabling a comparison between what is and what might have been, counterfactual thoughts amplify our emotional responses to bad outcomes. Well-known demonstrations such as the action effect (the tendency to attribute most regret to a character whose actions brought about a bad outcome) and the temporal order effect (the tendency to undo the last in a series of events leading up to a bad outcome) are often explained in this way. An important difference between these effects is that outcomes are due to decisions in the action effect, whereas in the temporal order effect outcomes are achieved by chance. In Experiment 1, we showed that imposing time pressure leads to a significant reduction in the action but not in the temporal order effect. In Experiment 2, we found that asking participants to evaluate the protagonists (

Patrimonio e Identidad en la Investigación Educativa Basada en las Artes desde un Enfoque Multimodal

Este artículo describe dos experiencias de investigación de nuestro grupo interconectadas, la primera desarrollada durante el año 2007 a través del proyecto internacional CALVINO del Programa Cultura 2000 de la Unión Europea, y la segunda implementada durante el año 2014 en el marco del Proyecto Investigación e Innovación en Secundaria en Andalucía (PIIISA). Ambos proyectos tienen en común el eje temático de la identidad a partir de una idea de patrimonio y el hecho de haber puesto en práctica metodologías de investigación basadas en las artes visuales con un enfoque multimodal. Desde estos dos puntos de anclaje relativos a la temática (qué) y a la metodología (cómo) analizamos lo acontecido para obtener conclusiones relevantes que, por una parte, pongan en valor estas prácticas significativas y, por otra, aporten nuestra experiencia para futuras propuestas de investigación en el ámbito temático y/o metodológico.

Discovery of multiple neuropeptide families in the phylum Platyhelminthes

Available evidence shows that short amidated neuropeptides are widespread and have important functions within the nervous systems of all flatworms (phylum Platyhelminthes) examined, and could therefore represent a starting point for new lead drug compounds with which to combat parasitic helminth infections. However, only a handful of these peptides have been characterised, the rigorous exploration of the flatworm peptide signalling repertoire having been hindered by the dearth of flatworm genomic data. Through searches of both expressed sequence tags and genomic resources using the basic local alignment search tool (BLAST), we describe 96 neuropeptides on 60 precursors from 10 flatworm species. Most of these (51 predicted peptides on 14 precursors) are novel and are apparently restricted to flatworms; the remainder comprise nine recognised peptide families including FMRFamide-like (FLPs), neuropeptide F (NPF)-like, myomodulin-like, buccalin-like and neuropeptide FF (NPFF)-like peptides; notably, the latter have only previously been reported in vertebrates. Selected peptides were localised immunocytochemically to the Schistosoma mansoni nervous system. We also describe several novel flatworm NPFs with structural features characteristic of the vertebrate neuropeptide Y (NPY) superfamily, previously unreported characteristics which support the common ancestry of flatworm NPFs with the NPY-superfamily. Our dataset provides a springboard for investigation of the functional biology and therapeutic potential of neuropeptides in flatworms, simultaneously launching flatworm neurobiology into the post-genomic era.
