In order to successfully traverse an actively complex environment, an agent is required to learn from the consequences of their actions. For over a century, models of behavior have been developed demonstrating these consequence-based learning systems. More recently, underlying biological systems have been found to adhere to these constructs of learning. The electroencephalographic signal known as the Reward Positivity (RewP) is thought to reflect a dopamine-dependent cortical signal specific to reward receipt. Importantly, this signal has been shown to adhere to an axiomatic (rule-like) positive reward prediction error, whereby it is evoked following outcomes that are better than expected. These …

Research suggests that there are two types of envy, a hostile version, aimed at depriving the envied person of his or her advantage, and a benign version, aimed at gaining an advantage for oneself (Parrott, 1991; van de Ven, Zeelenberg, & Pieters, 2009). Three predictions were derived from the hypothesis that the selection of envy type is functional, taking into account the costs and benefits of a benign versus a hostile response: 1) Hostile envy was expected to …
