Do blondes have more fun?
can't be sure about fun, but female blondes do make more money: This study contributes to the economics literature that links physical characteristics to labour market outcomes, by investigating the influence of hair colour on women's own wages and also their spouse's wages. Using U.S. panel data, we find that blonde women receive large wage premiums. Source: "Physical appearance and wages: Do blondes have more fun" from Economics Letters Join over 320,000 readers.

Does getting it wrong help you get it right?
s. Tests help learning even if you don't do well: Taking tests enhances learning. But what happens when one cannot answer a test question—does an unsuccessful retrieval attempt impede future learning or enhance it? The authors examined this question using materials that ensured that retrieval attempts would be unsuccessful. In Experiments 1 and 2, participants were asked fictional general-knowledge questions (e.g., “What peace treaty ended the Calumet War?”). In Experiments 3–6, participants were shown a cue word (e.g., whale) and…

Should you get wasted the night before a big exam?
re, why not? Despite what I recently posted about drinking negatively affecting performance in college, this study says that binge drinking the night before a test doesn't negatively affect grades: In a first-of-its kind controlled experiment, researchers from the Boston University School of Public Health (BUSPH) and Brown University have found that surprisingly, binge drinking the night before a test does not impact college students' test performance – although it can affect their moods, attention and reaction times. The study,…

Did all that drinking you did in college really hurt your grades?
ah, it did. Especially if you were smart: This paper examines the effect of alcohol consumption on student achievement by exploiting the discontinuity in drinking at age 21 at a college in which the minimum legal drinking age is strictly enforced. We find that drinking causes significant reductions in academic performance, particularly for the highest-performing students. This suggests that the negative consequences of alcohol consumption extend beyond the narrow segment of the population at risk of more severe, low-frequency, outcomes.…

How to quickly and easily become a better person
end more time out in nature: Four studies examined the effects of nature on valuing intrinsic and extrinsic aspirations. Intrinsic aspirations reflected prosocial and other-focused value orientations, and extrinsic aspirations predicted self-focused value orientations. Participants immersed in natural environments reported higher valuing of intrinsic aspirations and lower valuing of extrinsic aspirations, whereas those immersed in non-natural environments reported increased valuing of extrinsic aspirations and no change of intrinsic aspirations. Three studies explored experiences of nature relatedness and autonomy as underlying…

Is retirement lethal?
eviously I've posted on how retirement is correlated with cognitive decline. The proof keeps on rolling in: We investigate the relationship between aging, cognitive abilities and retirement using the Survey on Health, Aging and Retirement in Europe (SHARE), a longitudinal survey that offers the possibility of comparing several European countries using nationally representative samples of the population aged 50+. We use a version of the model proposed by Grossman (1972) as a guide for our empirical specification of the age-profile…

Is group studying more effective?
t if you want to remember anything: Humans routinely encode and retrieve experiences in interactive, collaborative contexts. Yet much of what we know about human memory comes from research on individuals working in isolation. Some recent research has examined collaboration during retrieval, but not much is known about how collaboration during encoding affects memory. We examined this issue. Participants created episodes by elaborating on study materials alone or collaboratively, and they later performed a cued-recall task alone, with the study…

Is it really “funny because it’s true”?
the "truth" resonates with the listener, yes: This study tests the folk psychological belief that we find things funny because we think they are true. Specifically, it addresses the relationship between implicit preferences and laughter. Fifty-nine undergraduate Rutgers University students (33 females and 26 males) from ethnically diverse backgrounds were videotaped while watching a white stand-up comedian for 30 min. Positive emotional expression associated with laughter was later scored using the facial action coding system (FACS). Computer-timed Implicit Association…
