Research has suggested that the default word order across languages is subject, object, then verb (SOV), so why have so many languages developed with a subject-verb-object (SVO) order? One explanation is the noisy-channel hypothesis, which supposes that individuals choose a speech pattern that gives the listener the best chance of understanding the original meaning of a message. In three experiments, participants looked at drawings and described the actions they showed using words and then using gestures. In English-, Japanese-, and Korean-speaking participants, the pattern of gestures versus the pattern of words supported the noisy-channel hypothesis.

To better understand the mechanisms underlying the perception of animacy — perception of an object as an animate being such as a mammal or insect — researchers examined the influences of extrinsic motion, body orientation, and spatial structure on participants’ rating of the animacy of biological motion depicted in point-light animations. Animacy ratings were higher when the background was naturalistic than when it was stationary and when the direction of gravity and congruency between intrinsic and extrinsic motions was maintained. This indicates that perceptions of animacy depend on both local intrinsic motion and congruency with global extrinsic motion and spatial structure.

Are there benefits to experiencing adversity? Participants reported their lifetime level of adversity before immersing their hands in ice-cold water. The researchers then measured participants’ level of catastrophizing, pain, positive and negative affect, and depression. Participants who had experienced moderate levels of life adversity had less negative responses to the pain of the cold water than did those who had experienced low or high levels of lifetime adversity. This suggests that experiencing moderate levels of adversity may lead people to be more prepared to deal with stress in the future.

Southgate and Begus test the hypothesis that the relationship between motor capability and action anticipation in infants is driven by access to a corresponding motor representation. The researchers measured infant’s brain activation in response to images of different actions, and they found that infants’ sensorimotor cortex was recruited regardless of whether they had a corresponding motor representation for the viewed action. This finding challenges the view that action prediction depends on motor correspondence.

Does temporal predictability benefit cognitive processing related to action or perception? Participants performed a speeded binary-choice task that consisted of two possible target symbols. The interval preceding the stimuli predicted which symbol would appear in some instances (correlated sets) but not in others (uncorrelated sets). Participants responded using four buttons they could operate with one (unimanual) or both (bimanual) hands. An interaction between the interval predictability and the interval frequency was seen in the unimanual group but not in the bimanual group, which suggests that specific temporal expectancy facilitates movement processing.
