The Implicit Association Test (IAT; Greenwald, McGhee, & Schwartz, 1998) is a computer-based categorization task that measures concept association strengths. Greenwald et al. (1998) demonstrated that participants completed the categorizations more quickly when pleasant and flower shared a response key than when pleasant and insect shared a response key, and when pleasant and White shared a resp...

Emotional stimuli have been shown to elicit increased perceptual processing and attentional allocation. The late positive potential (LPP) is a sustained P300-like component of the event-related potential that is enhanced after the presentation of pleasant and unpleasant pictures as compared with neutral pictures. In this study, the LPP was measured using dense array electroencephalograph both b...

This study proposes the following two methods applying two-dimensional DFA (detrended fluctuation analysis) and one-dimensional FFT (fast Fourier transform) algorithm: (1) a method for finding pleasant photographs of local tourist spots, and (2) a method for creating music from these photographs. We define “pleasant photograph” as the photograph containing 1/f noise components since it has been...

Mate-choice copying is shown when women imitate the mate-choice preferences of other women. We propose that the preferences of women with a pleasant character should be more influential than those of women with an unpleasant character and further suggest that this should apply only when the female demonstrates active interest in the male, rather than disinterest. Here, we presented women as hav...

Physical activity is a widely accessible and effective tool for improving well-being. This study aimed to unpack the feel-good effects of free-time physical activity. Multilevel models were applied to repeated measures of daily free-time physical activity and four types of feeling states obtained from 190 undergraduate students. Physical activity was not associated with pleasant-deactivated, un...

Mental imagery of events in the past or future, and of unpleasant or pleasant events, has been found to lead to spontaneous backward/forward bodily motions. Both time and emotion are represented along a spatial continuum, and activation of these representations seems to be simulated in spontaneous changes in body posture. We performed a conceptual replication and extension of an earlier study b...

Sentiment analysis and emotion detection are tasks with common features but rarely related because they tend to categorize the objects of their studies according to different categories, i.e. positive, negative and neutral values in SA, and emotion labels such as “joy”, “anger” etc. in emotion detection. In this paper we try to bridge this gap, reporting on three crowdsourcing experiments to co...

We examined the role of affect (pleasant or unpleasant feelings) and decision frames (gains or losses) in risk taking in a 20-day stock investment simulation in which 101 participants rated their current feelings while making investment decisions. As predicted, affect attenuated the relationships between decision frames and risk taking. After experiencing losses, individuals made more risky cho...
