What can you do to someone to make their lies easier to detect?
ntally exhaust them: We present two lie detection approaches based on cognitive theory. The first approach, 'measuring cognitive load', assumes that the mere act of lying generates observable signs of cognitive load. This is the traditional cognitive lie detection approach formulated by Zuckerman, DePaulo, & Rosenthal (1981). The second approach, 'imposing cognitive load', was developed by us (Vrij, Fisher, Mann, & Leal, 2006) and goes one step further. Here, the lie detector attempts to actively increase the differences between lying…

Here’s How Much Of Your Sexuality Is In Your Voice
ve you ever felt that someone might be sexy because of the sound of their voice? Well it's true. Voice attractiveness predicts symmetry, which is one of the primary markers of attractiveness: Previous research (Hughes et al. Evolution and Human Behavior 23:173–180, 2002) has shown that ratings of voice attractiveness are negatively correlated to fluctuating asymmetry (FA, a measure of developmental stability and fitness) but are unrelated to the second to fourth digit ratio (2D:4D, a measure of prenatal sex hormone…

Here’s What People Really Think Of Men Who Are Modest
a Daily Mail (Hat tip: David DiSalvo): Research has revealed women don't like modesty in a man...Other men also find male modesty an unattractive trait - perhaps because they believe that bashful boys are letting the side down. The three female researchers showed more than 200 people videotapes of a man and a woman applying for a job as a computer lab manager. The male and female actors both followed the same script in the mocked-up interview and were equally humble…

Can you tell how smart your child is by how early they start lying?
a BBC: Toddlers who tell lies early on are more likely to do well later, researchers claim. The complex brain processes involved in formulating a lie are an indicator of a child's early intelligence, they add. A Canadian study of 1,200 children aged two to 17 suggests those who are able to lie have reached an important developmental stage. Only a fifth of two-year-olds tested in the study were able to lie. But at age four, 90% were capable of…

Does alcohol really affect men’s sexual functioning?
though drinking often precedes men's sexual activity, basic questions about alcohol's effects on men's sexual arousal remain unanswered. Inconsistencies in findings from studies examining subjective and physiological effects on erectile functioning suggest these effects are context specific, for example, dependent on whether a man wants to maximize or suppress his arousal. To address unresolved questions about alcohol and erectile functioning, the authors evaluated the effects of high blood alcohol concentrations (BACs) and arousal instructional demands on indices of penile circumference…

Good Sex Keeps Marriage Stable Over The Long Term
xual satisfaction, marital quality, and marital instability have been studied over the life course of couples in many previous studies, but less in relation to each other. On the basis of the longitudinal data from 283 married couples, the authors used autoregressive models in this study to examine the causal sequences among these 3 constructs for husbands and wives separately. Results of cross-lagged models, for both husbands and wives, provided support for the causal sequences that proceed from sexual satisfaction…

Do We Love Our Families More As We Age?
e current study examined age differences in the intensity of emotions experienced during social interactions. Because emotions are felt most intensely in situations central to motivational goals, age differences in emotional intensity may exist in social situations that meet the goals for one age group more than the other. Guided by theories of emotional intensity and socioemotional selectivity, it was hypothesized that social partner type would elicit different affective responses by age. Younger (n = 71) and older (n =…

What kinds of friendships does Facebook promote?
..Facebook promotes mainly weak, low-commitment ties." Facebook offers the possibility of increased social contact via a process known as ‘friending’, whereby users create personal profiles and accumulate ‘friends’ on a reciprocal basis. The making and maintaining of friendships has been shown to be particularly important to young adults, but there is a strong debate in the literature on computer-mediated communication about the value of the often weak ties that are created. Relatively little is known about the kind of contact…
