I want a button box I can put between the mains and electric devices in my house. Hitting the button lets the electricity flow, turning the device on, and then after a delay the device turns off, freeing me from having think about turning lights etc off all the time. Why doesn’t this exist already?

This is a plot of the number of citations turned up by a simple “Web of Knowledge” search for papers containing the words “dopamine” and “reinforcement learning”, against year of publication. The rise, dating from approximately the time of publication of the first computational theory of phasic dopamine function, is rapid. There are, as far as I know, two computational theories of phasic dopamine function. One from Schultz, Dayan and Montague (1997) and one from our team here in Sheffield (Redgrave and Gurney, 2006)

This Prospect article by the RSA’s Matthew Taylor reviews an impressive amount of socially relevant psychology research. “Human nature is back”, announces Taylor, showing how the “useful shortcut” of the rational actor is now ready to be replaced by an empircally informed model of man as a social, emoitonal, being. Conclusions include
if we want to live an ethical life we do not have to pore over self-help books, but instead choose the social context that is most likely to prompt us to automatic altruism. Blinkered by the idea of humans as entirely driven by self-interest, we believe that altruistic acts must require conscious effort, perhaps as a result of exhortation from leaders. But if we are living balanced lives and enjoy mutual trust with people, behaving well comes naturally.
and
…susceptibility to social influence is hard-wired in us and not simply a characteristic of those lacking willpower. It may not be as catchy as the original slogan, but “tough on crime, even tougher on the causes of crime”is where the evidence points.
and
social institutions and cultural taboos are ways in which “generations hand down… vital tacit knowledge about human nature.”…[they] have developed to protect us from our psychological frailties, encouraging us to act long term and be socially responsible. These devices include the family, the church and civic organisations. As we become richer, we mistakenly think we do not need them.
It’s a rich brew of research evidence and political ideas. Perhaps even enough to give us hope, as Taylor claims that “new ideas about human nature can contribute to a more substantive meeting of minds between left and right”
LA Noire is the new game from Rockstar Games, the notorious publisher of Grand Theft Auto. This guardian article describes it as “a new era for interactive entertainment.”, where the gameplay is not about is not about hand-eye coordination but about emotional perception, being able to judge body language and facial “tells”.
The thing is, what will the “true” meaning of the facial expressions in the game be based on? Will the correct judgements be based on the game-designers’ intepretation of what different facial expressions mean? If so, how can we trust that they have the correct intepretation? It isn’t straightforward to read meaning from expressions. Even people who think they are experts at it can be wrong, and many of the clues popularity associated with deception, such as gaze aversion, don’t truly help you tell truth from lies (see the work of Aldert Vrij, at Portsmouth).
It might be that we end up playing a game where you learn to intepret what Rockstar games believes about what people look like when they lie, rather than practice any real world emotional perception
