Manipulation of Choice Behavior

See on Scoop.itBounded Rationality and Beyond

Downloadable! We introduce and study the problem of manipulation of choice behavior. In a class of two-stage models of decision making, with the agent’s choices determined by three “psychological variables,” we imagine that a subset of these variables can be selected by a “manipulator.” To what extent does this confer control of the agent’s behavior? Within the specified framework, which overlaps with two existing models of choice under cognitive constraints, we provide a complete answer to this question.

Emoticons in mind: An event-related potential study

See on Scoop.itBounded Rationality and Beyond

(2014). Abstract

It is now common practice, in digital communication, to use the character combination “:-)”, known as an emoticon, to indicate a smiling face. Although emoticons are readily interpreted as smiling faces, it is unclear whether emoticons trigger face-specific mechanisms or whether separate systems are utilized. A hallmark of face perception is the utilization of regions in the occipitotemporal cortex, which are sensitive to configural processing. We recorded the N170 event-related potential to investigate the way in which emoticons are perceived. Inverting faces produces a larger and later N170 while inverting objects which are perceived featurally rather than configurally reduces the amplitude of the N170. We presented 20 participants with images of upright and inverted faces, emoticons and meaningless strings of characters. Emoticons showed a large amplitude N170 when upright and a decrease in amplitude when inverted, the opposite pattern to that shown by faces. This indicates that when upright, emoticons are processed in occipitotemporal sites similarly to faces due to their familiar configuration. However, the characters which indicate the physiognomic features of emoticons are not recognized by the more laterally placed facial feature detection systems used in processing inverted faces.

Come la scienza del comportamento può ridurre la tua bolletta energetica

See on Scoop.itBounded Rationality and Beyond

C’è una via sicura per ridurre i vostri costi energetici? Non ci credereste: basta sapere quanto pagano i vostri vicini. Alex Laskey ci mostra come una particolare caratteristica del comportamento umano possa renderci migliori e più saggi consumatori di energia, con bollette più basse per dimostrarlo.
