Cheating the Lie Detector
In its war on terror, the U.S. government uses handheld lie detectors for fast screening of terrorism suspects. It has been shown that the pocket polygraphs have high error rates and are susceptible to successful faking, so the autobiographical Implicit Association Test (aIAT) was developed as an alternative lie detection tool. Initial assessments of the aIAT reported extremely high accuracy rates.

Study Suggests Left-Side Bias in Visual Expertise
Facial recognition is not as automatic as it may seem. Researchers have identified specific areas in the brain devoted solely to picking out faces among other objects we encounter. Two specific effects have been established as being critical for facial recognition – holistic processing (in which we view the face as a whole, instead of in various parts) and left-side bias (in which we have a preference for the left side of the face). Psychologists Janet H. Hsiao from the University of Hong Kong and Garrison W. Cottrell from the University of California, San Diego wanted to test if these effects were specific for facial recognition or if they help us to identify other objects as well.

Study Suggests Buddhist Deity Meditation Temporarily Augments Visuospatial Abilities
Meditation has been practiced for centuries, as a way to calm the soul and bring about inner peace. According to a new study in Psychological Science, a journal of the Association for Psychological Science, there is now evidence that a specific method of meditation may temporarily boost our visuospatial abilities (for example, the ability to retain an image in visual memory for a long time). That is, the meditation allows practitioners to access a heightened state of visual-spatial awareness that lasts for a limited period of time. Normally when we see something, it is kept in our visual short-term memory for only a brief amount of time (images will begin to fade in a matter of seconds).

Why You May Lose That Loving Feeling After Tying the Knot
Dating couples whose dreams include marriage would do well to step back and reflect upon the type of support they’ll need from their partners when they cross the threshold, a new Northwestern University study suggests. Will the partner who supports your hopes and aspirations while you are dating also help you fulfill important responsibilities and obligations that come with marriage? The answer to that question could make a difference in how satisfied you are after tying the knot. Believing a partner is there to help you grow into the person you aspire to be predicted higher relationship satisfaction for both dating and married couples, the study showed.

Financial Barriers to Attending College Affect Academic Goals in Young Students
Most young students do not enjoy homework. However, after being told that good grades will help them get into college and lead to a better life, most students eventually buckle down and start studying. But what if college is not an option? If a student thinks they won’t be able to afford a higher education – if the path towards college feels closed to them — they may conclude that studying and homework are a waste of time. Psychologists Mesmin Destin and Daphna Oyserman from the University of Michigan wanted to know at what age this thinking starts to set in and found out that this mentality and lack of motivation towards school occurs in children as young as 11 years of age.

The Price of Pain and the Value of Suffering
During these trying financial times, the cost of healthcare and how much we are willing to pay for it is at the top of our economic concerns. The financial value of pain has a wide ranging influence, affecting drug prices and injury compensation. But what about on an individual level — is it possible to place a value on our health, to prevent pain and suffering? University College London psychologists Ivo Vlaev and Nick Chater, and neuroscientists Ben Seymour and Raymond J. Dolan were interested in just how much money volunteers were willing to pay to avoid pain and discomfort.
