Have you ever been to an exclusive restaurant that serves tiny portions and found that, in spite of the paltry servings, you felt satisfied afterwards and the food seemed unusually tasty? If so, you might have engaged in what psychologists call "savouring" behaviours. Charles Areni and Iain Black have studied savouring under laboratory conditions, and they've found that when we're given smaller portions than normal, we eat differently – more slowly, more mindfully, and we feel more satiated as........

A new study has found that the pain reliever TYLENOL® (acetaminophen) not only dampens negative emotions, it blunts positive emotions too. Or does it?Durso and colleagues (2015) reckoned that if acetaminophen can lessen the sting of psychological pain (Dewall et al., 2010; Randles et al., 2013) – which is doubtful in my view – then it might also lessen reactivity to positive stimuli. Evidence in favor of their hypothesis would support differential susceptibility, the notion that the same ........ Read more »

'I' before the 'E' except after 'C'."Is childhood cat ownership a risk factor for schizophrenia later in life?"That was the rather peculiar question posed and partially answered in the paper by Fuller Torrey and colleagues . They concluded that "cat ownership in childhood is significantly more common in families in which the child later becomes seriously mentally ill."For those new to this topic, it might sound rather strange that cat ownership in childhood might elevate the risk of mental il........

We’ve written about power poses before and the work being done by Amy Cuddy and her colleagues on how they increase both self-confidence and hormones like testosterone and cortisol. The research has become so widely known it was even featured on the Grey’s Anatomy television show recently with two surgeons striking a superhero pose prior […]

"In conclusion, despite early parental concerns, children with ASD [autism spectrum disorder] receive less proactive provider responses to these concerns than children with ID/DD [intellectual disability/developmental delay]. Less proactive/more passive provider responses are associated with delays in diagnosing ASD."So said the paper from Katharine Zuckerman and colleagues  (open-access) who using "nationally representative data from the 2011 Survey of Pathways to Diagnosis an........

While knowledge and process are both important, knowledge is more important. Even though each of the tasks in this experiment was more “intuitive” (non-decomposable) than analytical in nature, and even when the approach taken to the task was “intuitive,” knowledge trumped process. Process had no significant effect by itself. Knowing stuff is good.... Read more »

Eat less, workout more, these are the messages we are being sent almost on a daily basis. But how do we quantify “more” and who really should listen to that advice? Well a new study suggests that engaging in low intensity activities such as standing may not be enough to offset the health hazards of sitting for long periods of time. On the bright side, adding two minutes of walking each hour to your routine just might do the trick.... Read more »

For adults, let alone children, time is a tricky concept to comprehend. In our culture, we carve it up into somewhat arbitrary chunks and attribute words to those durations: 60 seconds in a minute, and 60 of those in an hour and so on. We also have a sense of what these durations feel like. Children start using these time-related words at around the age of two or three years, even though they won't master clocks until eight or nine. This raises the question – what do young children really unde........ Read more »

It’s widely recognised that atheists are one of the most marginalised groups in the USA. As you might imagine, this can cause all sorts of problems for non-believers.

Telling people they are biased in their treatment of others – that they are racist or ageist, for example – can make them defensive and result in backlash. For this reason, change-makers nowadays often spread a different message: that stereotyping others isn’t a personal sin, but near-universal and something we must all aim to resist. However a new paper from researchers Michelle Duguid and Melissa Thomas-Hunt argues that this "Everyone Stereotypes" message, far from reducing bias, may act........ Read more »
