What’s stronger in eBay auctions: market economics or racism?
conduct a field experiment to determine whether racial discrimination can be identified in product-market auctions and, if so, under what conditions it is more likely to emerge. We compare the prices paid for perfectly substitutable products sold on eBay between sellers with distinctively white and distinctively black names. Price differences arise in favor of sellers whose names match the expected racial characteristics of buyers. However, the price differences only emerge in markets characterized by low levels of competition, and…

What effect does S+M have on relationships?
two studies, 58 sadomasochistic (SM) practitioners provided physiological measures of salivary cortisol and testosterone (hormones associated with stress and dominance, respectively) and psychological measures of relationship closeness before and after participating in SM activities. Observed activities included bondage, sensory deprivation, a variety of painful and pleasurable stimulation, verbal and non-verbal communication, and expressions of caring and affection. During the scenes, cortisol rose significantly for participants who were bound, receiving stimulation, and following orders, but not for participants who were…

Does the use of mobile phones affect short-term memory or attention?
. You can unwrap the tin foil from around your head now: The effect of acute exposure to low-level radio frequency electromagnetic fields (REF) generated by mobile phones on short-term memory and attention was assessed in two experiments. Most of the tests manipulated task difficulty or what might be termed cognitive load. This manipulation is important since previous studies have argued that exposure to mobile phones might affect cognitive functions only under conditions which tax the cognitive system. All participants…

Here’s What Makes A Good Gift, According To Research
you're trying to apologize to someone, expensive gifts work: The present study examined a costly signaling model of human apology. The model assumes that an unintentional transgressor is more motivated to restore the relationship with the victim than an intentional transgressor who depreciates the relationship. The model predicts the existence of a separating equilibrium, in which only sincere apologizers will pay a certain cost to restore the relationship, while dishonest apologizers will not. Accordingly, we hypothesized that the receivers…

A Quick And Easy Way To Relieve Stress
ew gum: The notion that chewing gum may relieve stress was investigated in a controlled setting. A multi-tasking framework which reliably evokes stress and also includes performance measures was used to induce acute stress in the laboratory. Using a randomised crossover design forty participants (mean age 21.98 years) performed on the multi-tasking framework at two intensities (on separate days) both while chewing and not chewing. Order of workload intensity and chewing conditions were counterbalanced. Before and after undergoing the platform participants…

Are famous people more likely to die on their birthday?
e authors assessed the relationship of mortality salience, as represented by birthdays, on the day of death. Preliminary studies considered the role of possible artifacts such as seasonality of birth and death, and time units for evaluation. On the basis of terror management theory's concept of “mortality salience,” the authors hypothesized that famous people, in this case Major League Baseball (MLB) players, would be more likely to die on or after their birthdays than would be expected by chance (the…

Here’s How Many Guys Fake Orgasms
search shows that many women pretend or “fake” orgasm, but little is known about whether men pretend orgasm. The purpose of this study was to investigate (a) whether, how, and why men pretend orgasm and (b) what men's and women's reports of pretending orgasm reveal about their sexual scripts and the functions of orgasms within these scripts. Participants were 180 male and 101 female college students; 85% of the men and 68% of the women had experienced penile-vaginal intercourse (PVI).…

Do we need to be afraid of killer robots?
parently, yes: In 1981, a 37-year-old Japanese employee of a motorcycle factory was killed by an artificial-intelligence robot working near him. The robot erroneously identified the employee as a threat to its mission, and calculated that the most efficient way to eliminate this threat was by pushing him into an adjacent operating machine. Using its very powerful hydraulic arm, the robot smashed the surprised worker into the operating machine, killing him instantly, and then resumed its duties with no one…
