Until now, we knew little about the height and weight of our ancestors who lived between 2.5 and 1.5 million years ago. Co-author of the study, Manuel Will, says [...]

Probably not, as it turns out. In a new study published in the Quarterly Journal of Experimental Psychology, UCLA psychologists found that almost none of their subjects could draw the logo correctly from memory. [...]

For the study, published in Psychological Science, 563 visitors to the London Science Museum were asked to rate the riskiness of everyday [...]

Evolutionary novelties in visionhttp://www.psypost.org/2015/03/evolutionary-novelties-in-vision-32849 http://www.psypost.org/2015/03/evolutionary-novelties-in-vision-32849#comments Sat, 28 Mar 2015 15:19:40 +0000 http://www.psypost.org/?p=32849 A new study from SciLifeLab at Uppsala University published in PLOS ONE shows that genes crucial for vision were multiplied in the early stages of vertebrate evolution and acquired distinct functions leading to the sophisticated mechanisms of vertebrate eyes. One striking feature of vertebrates is the prominent role that vision plays in almost all major [...]

However, the molecular mechanisms underlying music performance have been so far unexplored. A Finnish research group has now investigated the effect of music performance (in a 2 hr concert) on the gene expression profiles of professional musicians from [...]

The findings, published in The Journal of Neuroscience, help to describe [...]

During tasks that require our attention, we might become so engrossed in what we are doing that we fail to notice there is a better way to get the job done. For example, let’s say you are coming out of a New York [...]

That’s because uncertainty, a long-known cause of anxiety, makes it difficult to prepare for events or to control them. People vary [...]

Disgust has many functions. It protects us from products that might cause us harm (food that has gone off), it can give us a moral compass (when we see someone [...]
