How Do Babies Learn to Be Wary of Heights?
Infants develop a fear of heights as a result of their experiences moving around their environments, according to new research published in Psychological Science, a journal of the Association for Psychological Science. Learning to avoid cliffs, ledges, and other precipitous hazards is essential to survival and yet human infants don’t show an early wariness of heights. As soon as human babies begin to crawl and scoot, they enter a phase during which they’ll go over the edge of a bed, a changing table, or even the top of a staircase.

Going Through the Motions Improves Dance Performance
Expert ballet dancers seem to glide effortlessly across the stage, but learning the steps is both physically and mentally demanding. New research suggests that dance marking -- loosely practicing a routine by “going through the motions” -- may improve the quality of dance performance by reducing the mental strain needed to perfect the movements. The new findings, published in Psychological Science, a journal of the Association for Psychological Science, suggest that marking may alleviate the conflict between the cognitive and physical aspects of dance practice, allowing dancers to memorize and repeat steps more fluidly.

New Research From Psychological Science
Read about the latest research published in Psychological Science. Time in Perspective Andrei Gorea and Janice Hau Researchers know that the perceived size of an object increases as its perceived distance from an observer increases (Emmert's law) and that the perceived time interval between two consecutively occurring stimuli increases when the distance between them is greater (Kappa effect). What happens when these two perceptual phenomena are induced together? The researchers found that people overestimated the perceived duration of objects moving in a distant plane relative to the perceived duration of the same objects moving in a closer plane.

Inner Speech Speaks Volumes About the Brain
Whether you’re reading the paper or thinking through your schedule for the day, chances are that you’re hearing yourself speak even if you’re not saying words out loud. This internal speech -- the monologue you “hear” inside your head -- is a ubiquitous but largely unexamined phenomenon. A new study looks at a possible brain mechanism that could explain how we hear this inner voice in the absence of actual sound.
