Research paper thumbnail of The influence of feedback on detection and recognition memory of fake news: an experimental study from the perspective of signal detection theory

Los experimentos se dividieron en 2 fases: discriminación y memoria de reconocimiento de noticias. Se contó con la participación de 93 jóvenes, quienes juzgaron la veracidad o falsedad de las noticias utilizando una tarea de elección forzada, en 24 noticias con dos tipos de atributos, físicos y no físicos. Los resultados indicaron en el experimento 1, que los atributos no físicos alteran la detección y memoria de reconocimiento de las noticias, haciendo irrelevante el atributo físico del color de la tipografía. En el experimento 2, se observó que la retroalimentación inmediata mejora la detección, pero no el reconocimiento que se ve alterado por los atributos no físicos igual que en el experimento 1. Estos hallazgos evidencian la necesidad de presentar a los lectores de noticias, diferentes fuentes de verificación inmediata para mejorar su detección, así como la urgencia de generar en el sector de comunicación buenas prácticas de verificación de la información.

Research paper thumbnail of Effect of masculine eating and drinking beliefs on male consumers’ concern with healthy eating and binge drinking

Additionally, this research tests if and how a change in these beliefs influences binge drinking intention and intention to eat unhealthy food. Design/methodology/approach Three studies were conducted in Bogotá (Colombian males; convenience sampling). The purpose of Study 1 (N = 209) was to develop a scale to measure masculine eating/drinking beliefs. Study 2 (N = 191) tested the mediating role of concern with unhealthy eating/drinking habits in the relationship of masculine eating/drinking beliefs with binge drinking. Study 3 (N = 179) was an experimental study, which examined the effect of information about some negative consequences of masculine beliefs on the answers to the masculine eating/drinking beliefs inventory and, in turn, on binge drinking intention and intention to eat u...

En tal sentido, la gestión organizacional supone el equilibrio en la aplicación de paradigmas y supuestos teóricos y prácticos que orientan el propósito organizacional a partir de sus características sustanciales, su espíritu emprendedor y su capacidad funcional que si bien debe operar en contexto influenciado por las dinámicas sociales, económicas y políticas del momento, no puede perder de vista los componentes de eficiencia, eficacia, efectividad y calidad; lo que demanda ...

One food was always followed by gastric malaise in one of the contexts, while other foods were not followed by gastric malaise in the same, or in an alternative context. Predictive responses and eye-fixations were recorded throughout the 48 training trials with each cue involved in the task. In agreement with the predictions of the Attentional Theory of Context Processing, attention to the contexts measured through eye-fixations decreased while attention to the cues increased as training progressed. The results of this study give support to the idea that contexts are actively processed at the beginning of acquisition, and that this processing decreases as training increases.

Drinking was induced by a Fixed-Time 30 sec food delivery schedule (FT30). Experiment 1 used a 2 x 2 factorial design with Schedule (FT30 vs. food at the start of the session), and Stimulus (Presence or absence of a 10 sec tone at the end of each 30 sec period within a session) as factors. Acquisition and extinction were conducted in two different contexts, returning to the acquisition context at testing. Experiment 2 tested contextual control of extinction against a control that remained in the extinction context at testing. Recovery from extinction was observed as an increase in water intake (as well as in magazine entries) during the test, regardless of the presence of the tone. Implications for the understanding of schedule-induced drinking as a conditioned response are discussed.

This effect is well established but its mechanism is not well understood. In the studies described below we assessed whether the saliences of configural and element cues were affected by prior training. We observed positive transfer to a new configural discrimination after configural pre-training but we were unable to find evidence for changes in cue salience using a signal-detection task. Our results confirm previous work by demonstrating experience-dependent flexibility in cue processing but they also suggest that this flexibility occurs at a point in the stimulus processing pipeline later than 1–2 s after the presentation of stimulus inputs.
