Using data from 23 studies of what psychologists call “inequity aversion,” Berkeley researchers combed through results of more than 60,000 observations involving 18 animal species. In what they said was the “largest empirical investigation of non-human inequity aversion to date,” the team reconstructed data analyses and used a new metric that adds depth to the concept of fairness. “We can’t make the claim that animals experience jealousy based on this data,” said Oded Ritov, a fourth-year Ph.D. candidate in UC Berkeley’s Department of Psychology. “If there is an effect, it’s very weak and might show up in very specific settings. 

Research on allergic diseases requires knowledge from multiple scientific disciplines including, but not limited to, microbiology, genetics, botany, environmental sciences and data sciences. The disease’s pathology may involve many different areas within the body. The critical allergens can range from airborne plant matter, insects, molds, manufactured materials, food or even elements of one’s own body. Given this complexity, ensuring a diversity of different disciplines within a research team should increase the team’s research output.

For parents trying to shield their children from online threats, limiting screen time is a common tactic. Less time scrolling, the rationale goes, means less exposure to the psychological dangers posed by social media. 

But research from Rutgers University-New Brunswick upends this assumption. Writing in The Journal of Child Psychology and Psychiatry, Jessica L. Hamilton, an assistant professor in the Department of Psychology at the School of Arts and Sciences, reports that screen time has no effect on whether adolescents contemplated suicidal thoughts.

Excessive screen use by preschool-age children can lead to reduced sleep quality, exacerbating problems such as poor attention, hyperactivity and unstable mood, a new study suggests.
