Certain smiles aren't all they're cracked up to be

A new study found that 'dominance' smiles, which signal disapproval, increase physical stress and challenge social standing. In contrast, 'reward' and 'affiliation' smiles, which reinforce behavior, facilitate or maintain social bonds.

UNLV study reveals breakthrough in decoding brain function

The research team discovered a neural signal in the brain's ACC that detects unexpected outcomes, offering clues to the cellular origin of feedback negativity. This finding has significant implications for our ability to detect situations where we can learn more effectively.

Negative feedback loops help maintain the function of mutated proteins

Researchers found that negative feedback loops act as a shock absorber to buffer damage from mutations, allowing genes to mutate without compromising function. This mechanism may foster long-term adaptation while reducing immediate fitness risk, with implications for evolution and cancer treatment.

Doubts about career potential can pave way for immoral professional conduct

Researchers found that negative feedback can prompt immoral behavior in high-achieving students pursuing careers in law, business, and STEM fields. Those who received negative feedback were more likely to endorse questionable behaviors, such as breaking contracts or disparaging others, to demonstrate their professional capabilities.

Finding fake feedback

Researchers develop algorithm to identify and block falsified feedback, ensuring ecommerce trust management systems' integrity. The algorithm uses a clustering approach to group similar ratings together and determine the credibility of individual ratings.

Researcher builds a better job performance review

A Kansas State University researcher has found that nobody likes negative feedback, even those trying to learn. Culbertson suggests focusing on constructive feedback, avoiding numerical ratings, and eliminating the 'sandwich' approach. This can help managers improve employee motivation, commitment, and performance.

Feedback can have a negative impact on performance

A study published in Frontiers in Neuroscience found that people's performance worsened when they had to make sense of feedback while performing a main task. The research highlights the importance of considering task complexity when providing feedback to avoid hindering performance.

Retail therapy: Shopping to cope with future challenges

A new study reveals that consumers shop proactively to protect themselves against potential challenges, yet reactively after experiencing stress. They tend to choose products specifically associated with bolstering or guarding the self under threat.

Why do experts seek negative feedback to get motivated?

A study found that experts are more motivated by negative feedback than novices, while novices respond better to positive feedback. This suggests that marketers should target experts with negative feedback to promote motivation and change attitudes.

GoPro HERO13 Black records stabilized 5.3K video for instrument deployments, field notes, and outreach, even in harsh weather and underwater conditions.

When words get hot, mental multitaskers collect cool

Research by Demaree and Schmeichel found that people with high working memory capacity are better at controlling their emotions after receiving harsh criticism. They use a coping mechanism to make themselves feel better, resulting in less negative emotions.

Why the eye is better than a camera

Researchers discovered that the human eye's horizontal cells boost photoreceptor signals while preserving contrast, allowing for sharper images with less sacrifice of shadow detail. This positive feedback mechanism is found across vertebrates and is thought to be responsible for the eye's ability to detect faint details near edges.

Soil-borne pathogens drive tree diversity in forests, study shows

Research led by University of Wisconsin-Milwaukee scientists finds that soil-borne pathogens drive species diversity and explain patterns of tree abundance. The study's findings suggest that certain tree species are more susceptible to pathogens, which prevents rare species from becoming abundant.

Uncertainty can be more stressful than clear negative feedback

A new study published in Psychological Science found that individuals with high neuroticism levels prefer clear negative information over uncertainty. Researchers measured brain activity and found stronger responses to uncertain feedback in these individuals.

Uncertainty can be more stressful than clear negative feedback

A new study published in Psychological Science found that neurotic individuals react stronger to uncertain feedback than clear negative information. This suggests that some people prefer the devil they know over the unknown, and high levels of Neuroticism contribute to this dislike.
