Study reveals lack of self-awareness among doctors when prescribing opioids

A study found that 65% of emergency department physicians underestimated their opioid prescription rates, but rates decreased after they saw their actual data. The researchers believe this change was due to the shock of seeing the reality of their actions versus their perceptions, priming them to make a change.

Newborn babies have built-in body awareness ability

Researchers found that newborn babies show signs of body awareness by differentiating their own bodies from others. They exhibit interest in looking at another baby's face when it is stroked synchronously with their own, suggesting a mechanism for self-perception already in place.

Visualized heartbeat can trigger 'out-of-body experience'

Researchers used visual projections of human heartbeats to alter subjects' perception of their body, inducing an out-of-body experience. The study suggests a novel approach to treating self-perception disorders like anorexia and body dysmorphic disorder.

Reverse inclusion and the question of disability

A University of Alberta study found that female athletes with disabilities value the inclusion of able-bodied teammates for promoting equality, strength, and competition opportunities. However, differences in injury experiences and perceptions of disability still exist.

How we come to know our bodies as our own

A recent study has identified the brain regions responsible for our sense of body ownership, revealing a unified view of the body as a single entity. The findings suggest that multisensory neurons integrate visual, tactile, and proprioceptive information to facilitate full-body ownership.

Nearly 25 percent of overweight women misperceive body weight

New research finds nearly 25% of overweight and 16% of normal-weight reproductive-age women misperceive their body weight, leading to unhealthy weight loss behaviors. Clinicians are recommended to calculate BMI, screen for misperceptions, and counsel patients to address this issue.

Are you a different person when you speak a different language?

Depression symptoms less likely in kids with accurate self-perceptions

A Florida State University study found that kids with realistic perceptions of social acceptance are better equipped to handle negative feelings, reducing depressive symptoms. The researchers discovered a self-perpetuating cycle where inaccurate perceptions lead to depression, and depression worsens accuracy.

Having inaccurate self-insights has serious consequences

A Cornell University expert warns that people's capacity to evaluate themselves is usually modest, leading to overinflated views of expertise and character. This can have far-reaching implications in various aspects of life. The expert suggests that people should be more cautious about what they know and do not know about themselves.

What we cannot do ourselves, we cannot understand in others

Two patients with a rare illness lost ability to perceive their own body, yet could correctly guess weight of boxes lifted by others. They relied on internal simulation to interpret body movements, suggesting our brains simulate others' actions to understand their intentions.

Selling your self and losing your memory

A study by Lastovicka and Fernandez found that people use divestment rituals to purge bad memories when giving away possessions. By offering prized possessions to strangers, individuals can maintain a sense of shared identity and boundary between self and other.
