Choosing between past and future regret

Sometimes decisions imply trade-offs that force people to accept missing an opportunity in the past or in the future. It has not yet been clarified whether a past miss or a future miss elicits more regret. In a direct comparison, Shani, Danziger, and Zeelenberg found support for the greater impact of future misses. In an experimental design with 216 students, we replicated their study and tested the strength of the future miss in a separate evaluation and with different periods. The results show that future misses cause less regret than past misses do when evaluated separately. However, future misses made participants change their feelings of regret more than past misses did. Feelings of regret did not decrease when future misses were further away. Our findings support the strength of future misses on regret but also show contrasting effects when evaluated separately. This indicates the further need for research in this topic.

An introduction to the fractional continuous-time linear systems

A brief introduction to the fractional continuous-time linear systems is presented. It will be done without needing a deep study of the fractional derivatives. We will show that the computation of the impulse and step responses is very similar to the classic. The main difference lies in the substitution of the exponential by the Mittag-Leffler function. We will present also the main formulae defining the fractional derivatives.
