Women with high family support and limited pressure to achieve the 'thin and beautiful' ideal have a more positive body image. That's according to a new study looking at five factors that may help young women to be more positive about their bodies, in the context of a society where discontent with appearance is common among women.
Emotion can shut down high-level mental processes without our knowledge, in our native language
Psychologists believe that they have glimpsed for the first time, a process that takes place deep within our unconscious brain, where primal reactions interact with higher mental processes. They have identified a reaction to negative language inputs which shuts down unconscious processing. The psychologists extrapolate this from their most recent findings working with bilingual people.

Not only is there a real connection between vision and other senses, but that connection is important to better understand the underlying mechanisms that can quickly trigger sensory changes, according to new research.
Gestures fulfill a big role in language
People of all ages and cultures gesture while speaking, some much more noticeably than others. But is gesturing uniquely tied to speech, or is it, rather, processed by the brain like any other manual action? Scientists have discovered that actual actions on objects, such as physically stirring a spoon in a cup, have less of an impact on the brain’s understanding of speech than simply gesturing as if stirring a spoon in a cup.
