Chemotherapy drug may increase vulnerability to depression A chemotherapy drug used to treat brain cancer may increase vulnerability to depression by stopping new brain cells from growing, according to a new study.
How Education Research Can Track Within-Person Changes Education research should focus on situations and processes, not just on differences between groups of people. Intrapersonal research advocates personalized approaches to learning.
It's Not the Glass that's Half Full/Empty; It's the Breast We judge others as dispositioned towards negativity or positivity, scarcity or abundance, as a chosen disposition. In truth, that disposition gets set in infancy.
Movie research results: Multitasking overloads the brain Previous research shows that multitasking, which means performing several tasks at the same time, reduces productivity by as much as 40%. Now a group of researchers specializing in brain imaging has found that changing tasks too frequently interferes with brain activity. This may explain why the end result is worse than when a person focuses on one task at a time.
Genetics, environment combine to give everyone a unique sense of smell Receptors in the noses of mice exposed to certain smells during life are different to genetically similar mice that lived without those smells, new research shows. The study found it is this combination of genetics and experience that gives each individual a unique sense of smell.
Facial expressions: How brains process emotion The amygdala has distinct neurons that judge the intensity and ambiguity of facial expressions, new research shows. Identifying the amygdala's role in social cognition suggests insights into the neurological mechanisms behind autism and anxiety.
Novel mode of antidepressant action may help patients unresponsive to SSRIs Scientists have identified a novel mode of action for a potential antidepressant that also leads to nerve cell growth in the mouse hippocampus. The activator of a serotonin receptor uses a different mechanism to the most commonly used antidepressants, SSRIs. This is a promising finding for the millions of patients who do not respond well to current treatments.
Predicting people's 'brain age' could help to spot who is at risk of early death A method for predicting someone's 'brain age' based on MRI scans could help to spot who might be at increased risk of poor health and even dying at a younger age.
Parents' use of emotional feeding increases emotional eating in school-age children Emotional eating is not uncommon in children and adolescents, but why youth eat emotionally has been unclear. Now a new longitudinal study from Norway has found that school-age children whose parents fed them more to soothe their negative feelings were more likely to eat emotionally later on. The reverse was also found to be the case, with parents of children who were more easily soothed by food being more likely to feed them for emotional reasons.
Low levels of 'memory protein' linked to cognitive decline in Alzheimer's disease This discovery may lead to important research and may one day help experts develop new and better therapies for Alzheimer's and other forms of cognitive decline.

Caudate stimulation enhances human associative learning Associative learning allows an individual to acquire an association between a sensory cue and an outcome resulting from a specific response. Associative learning plays a vital role in the ability to learn new associations that allow human beings to optimally respond to the world around them. Research in humans and primates supports an important role for the caudate in associative learning. Our objective was to determine whether caudate stimulation could modulate associative learning in humans and to examine the neural circuitry involved in this process.
Aerobic, resistance exercise combo can boost brain power of over 50s A combination of aerobic and resistance exercises can significantly boost the brain power of the over 50s, finds the most comprehensive review of the available evidence to date.
Empathy study finds low dose of MDMA makes people feel more concerned for others A team of researchers from the Netherlands and Switzerland have confirmed that the drug 3,4-methylenedioxymethamphetamine (MDMA) — commonly known as ecstasy or molly — enhances empathy towards others. The findings, published April 3 in the Journal of Psychopharmacology, are based on a pooled sample of 118 participants from six double-blind placebo-controlled studies. The participants ingested [...]
Art connoisseurs tend to rely on prestige as an indicator of quality, study finds New research helps explain why experts’ preferences often deviate from laypeople’s preferences in the realm of art. The two-part study, published in the peer-reviewed journal Human Nature, found that expert appreciation of artwork was driven in part by a prestige bias. An initial experiment with 151 undergraduate students found that laypeople appreciate portrait photographs depicting [...]
Hypnosis may still be veiled in mystery – but we are starting to uncover its scientific basis Some argue that hypnosis is just a trick. Others, however, see it as bordering on the paranormal – mysteriously transforming people into mindless robots. Now our recent review of a number of research studies on the topic reveals it is actually neither. Hypnosis may just be an aspect of normal human behaviour. Hypnosis refers to [...]
Fragmentation of Personality Given the complexity of our online lives, how do we define the totality of who we are? Is this changing how we think of being integrated human beings and our creative lives?
