  1. The seductive power of curiosity: When it overrides physical risk – an fMRI investigation, Johnny King, Lau, Hiroki Ozono, Asuka Komiya, Kou Murayama, Organization for Human Brain Mapping, 2017/06/27, Without Invitation, English, Vancouver, Why did Pandora open the box, even though she had been warned not to? – Because she could not resist the power of curiosity. Curiosity can be conceptualized as the feeling that creates a strongly-felt volitional desire for new knowledge to resolve gaps in it[1]. As a fundamental part of human motivation, curiosity supports an enormous variety of intellectual behaviours, for example scientific discovery. A meta-analysis revealed that curiosity predicts academic performance above and beyond intelligence[2], corroborating findings that it facilitates long-term consolidation of learning[3]. Surprisingly, little attention has been paid to one of the most essential nature of curiosity: its seductive power to influence behaviours. Also, to date only a few neuroimaging studies have examined the neural correlates of curiosity[3-5]. They have implicated the reward-system in the brain[3-4], which is commonly activated by extrinsic incentives. This study examined how curiosity biases our decision-making, even in the face of physical risk (e.g. expecting electric stimulation), and evaluated the relevant underlying neural mechanisms using fMRI. To induce curiosity, we have created and pilot-tested a set of videos of magic tricks performed by professional magicians. A magic trick shows an event that is apparently impossible, thus an ideal material to create strong knowledge gap.
  2. When the seductive power of curiosity overrides prospective risk- the underlying neural mechanism, Johnny King, Lau, Kei Kuratomi, Hiroki Ozono, Asuka Komiya, Kou Murayama, the 13th International conference for cognitive neuroscience, 2017/08/06, Without Invitation, English, Amsterdam, Why would Pandora open the box, even after she was warned? This study examined how curiosity biases decision-making, even in the face of physical risk (e.g. expecting electric stimulation), and evaluated the relevant underlying neural mechanisms using fMRI. To induce curiosity, we pilot-tested a set of videos of magic tricks performed by professional magicians. A magic trick shows an event that appears impossible, thus an ideal material to create strong knowledge gap as a source of curiosity. Thirty-one healthy, right-handed participants (5 male; age: 18-30yos) were presented with magic trick videos (n=36) and images of food in a 3T Siemens scanner. In every trial, after the presentation of a fixation and a video, participants were asked to rate how curious they were to know the solution. Then, they were shown a wheel of fortune representing a lottery which visualized the probability of winning (and losing), and were asked to decide whether to gamble. If they gambled and won, they were provided with a ticket to see the solution. They were instructed that if they lost, they would receive a mild electric shock after the experiment. Participants could also opt to skip the lottery. Prior to the fMRI experiment, we evaluated the paradigm with a separate participant group. Behavioural data were fitted into a generalised linear mixed-effects model, which showed that increased probability of expecting a reward, as well as curiosity, increased individual’s tendency to take risk (corroborating past findings). Neuroimaging analysis (using SPM12) compared the BOLD signals of the ‘accepted’ and ‘rejected’ trials at the time of decision making. In particular, the accepted (versus rejected) magic trials were associated with greater striatal activity, commonly regarded as part of the brain’s reward system.
  3. Making Use of Regret Increases the Number of One's Friends, Asuka Komiya, Ai Mizokawa, Takayuki Goto, 18th general meeting of the European association of social psychology, 2017/07/06, Without Invitation, English, Granada, Spain, The study objective was to determine whether individual tendencies to experience, anticipate, and make use of regret influence social adaptation. It has been argued that regret has a functional value as owing to the associated pain, it leads to better decision-making, causing people to avoid similar failure in the future. While it has been demonstrated in many studies that regret improves what to do with the experimental tasks or academic performance in intrapersonal situations, how it functions in interpersonal situations has not been explored very often. The focus of the current study was on how individual differences regarding anticipation, and making use of and experiencing regret, contribute to social adaptation, such as the ability to make friends. Respondents read a vignette which described a situation whereby they drew a lot (one of two) and received second prize. They were then immediately told that the unchosen lot was the winning prize. Respondents had to rate their feelings before and after they knew that they had had a chance of winning but had lost the first prize (i.e., the tendency to anticipate and experience regret). After completing the rating exercise, they had to indicate which lot they would like to choose the future (i.e., the tendency of making use of regret). They then reported the number of their friends. It was found that experiencing regret correlated negatively, and making use of regret correlated positively, with the number of friends reported. This relationship remained significant, even after controlling for age and sex.
  4. Regret facilitates learning: A card game experiment, Asuka Komiya, Takayuki Goto, Toshiyuki Himichi, Kou Murayama, Michiko Sakaki, International Congress of Psychology, 2016/07/29, Without Invitation, English, Yokohama, Japan, Researchers have argued that regret promotes appropriate behavior by embodying painful lessons of past failure. In the present study, we developed a new paradigm to investigate the learning effect of regret, controlling for the feedback information. In the task, participants chose a card between two decks, obtained the point written on it, and tried to maximize their accumulated points. In the regret condition, in addition to the point they obtained, participants were shown a point they could have obtained if they had chosen a card from the other deck. In the non-regret condition, participants were given a point associated with another card that was not used in the trial. The results showed that as trials passed, participants in the regret condition were more likely to choose a card from the more rewarding deck than were those in the non-regret condition. The usefulness of the task has been discussed.
