The ability to block a moving ball affected the ball’s perceived speed

Is There a Chastity Belt on Perception? Jessica Witt, Nathan Tenhundfeld and Michael Tymoski. Psychological Science,  https://doi.org/10.1177/0956797617730892

Abstract: Can one’s ability to perform an action, such as hitting a softball, influence one’s perception? According to the action-specific account, perception of spatial layout is influenced by the perceiver’s abilities to perform an intended action. Alternative accounts posit that purported effects are instead due to nonperceptual processes, such as response bias. Despite much confirmatory research on both sides of the debate, researchers who promote a response-bias account have never used the Pong task, which has yielded one of the most robust action-specific effects. Conversely, researchers who promote a perceptual account have rarely used the opposition’s preferred test for response bias, namely, the postexperiment survey. The current experiments rectified this. We found that even for people naive to the experiment’s hypothesis, the ability to block a moving ball affected the ball’s perceived speed. Moreover, when participants were explicitly told the hypothesis and instructed to resist the influence of their ability to block the ball, their ability still affected their perception of the ball’s speed.


Consumers who experience the sensation of going against the flow pick alternatives that are normatively not preferred

Going against the Flow: The Effects of Dynamic Sensorimotor Experiences on Consumer Choice. Mina Kwon and Rashmi Adaval. Journal of Consumer Research, ucx107, https://doi.org/10.1093/jcr/ucx107

Abstract: Sensorimotor experiences of going against the flow can affect the choices consumers make. Eight experiments show that consumers who experience the sensation of going against the flow pick alternatives that are normatively not preferred (experiments 1a and 1b). These effects are evident only when the sensations are dynamic and self-experienced (experiments 2a and 2b), subjective feelings are elicited (experiments 4a and 4b) and no other objective, external norm information is supplied (experiment 5). Experiences of going against the flow typically involve both movement and direction and are represented in memory schematically. Re-experiencing these sensations leads to the activation of this schematic representation and elicits a feeling-based behavioral disposition to do something different, or to go against one’s initial inclination (experiment 3), leading participants to pick an option that is normatively not preferred

Indoor Prostitution Lowers Sex Crime: Evidence from New York City

The Effect of Indoor Prostitution on Sex Crime: Evidence from New York City. Riccardo Ciacci & MarĂ­a Micaela Sviatschi. Columbia University Working Paper, November 25 2016. http://www.micaelasviatschi.com/wp-content/uploads/2016/05/sex_crimeNYC.pdf

Abstract: We use a unique data set to study the effect of indoor prostitution establishments on sex crimes. We built a daily panel from January 1, 2004 to June 30, 2012 with the exact location of police stops for sex crimes and the day of opening and location of indoor prostitution establishments. We find that indoor prostitution decreases sex crime with no effect on other types of crime. We argue that the reduction is mostly driven by potential sex offenders that become customers of indoor prostitution establishments. We also rule out other mechanisms such as an increase in the number of police officers and a reduction of potential victims in areas where these businesses opened. In addition, results are robust to different data sources and measures of sex crimes apart from police stops.
