The present study was aimed at investigating whether and how the explicit representation of the decision outcome, framed in terms of lives saved or lost, could affect decision choices, emotional experience, and decision times in the course of a moral dilemma task. Decision outcomes were framed in a between-group design by means of smiling or injured faces depicting, respectively, the lives saved or lost with each choice. A control condition with no frame and no outcome was included. Results showed that (...) behavioral choices were highly resistant to the framing manipulation in both dilemma types. However, an overall reduction in the number of utilitarian choices and in the decision times, associated with an increase in unpleasantness during decision-making, was found, suggesting a progressive increase in aversive emotional activation favoring the rejection of utilitarian resolutions. Interestingly, at the beginning of the task, the POS group showed a delay in decision times as compared with the NOF group, specifically for footbridge-type dilemmas. This result might be interpreted as an interference effect temporarily slowing decision-making during the resolution of dilemmas in which the internal representation is spontaneously focused on the personal cost of causing intentional harm to others.

The spatial-temporal association indicates that time is represented spatially along a left-to-right line. It is unclear whether the spatial-temporal association is mainly related to a perceptual or a motor component. In addition, the spatial-temporal association is not consistently found using a time reproduction task. Our rationale for this finding is that, classically, a non-lateralized button for performing the task has been used. Using two lateralized response buttons, the aim of the study was to find a spatial-temporal association in a time (...) reproduction task. To account for the perceptual component, reference and target stimuli were presented in different spaces through four experiments. In all experiments, a Spatial-Temporal Association of Response Codes (STEARC) effect was found and this effect was not modulated by the spatial position of both reference and target stimuli. The results suggested that the spatial-temporal association was mainly derived from the spatial information provided by response buttons, reflecting a motor but not visuospatial influence. (shrink)

According to Gilead and colleagues, to be efficient abstraction requires a hierarchical organization of information into long-term memory. But, how and when are abstract representations consolidated into long-term memory and how are they integrated with pre-existing abstracta are questions not discussed by Gilead and colleagues. Here, we propose that these processes occur preferentially during offline periods such as sleep.
