A new study published in PNAS looked at how expert navigators deploy rational complexity–based decision precaching for large-scale real-world planning. “Our study is about the intricate planning processes of London taxi drivers, who are renowned for their exceptional knowledge of the city's layout,” study author Daniel C. McNamee told us. “We aimed to uncover how these expert navigators manage the complex task of route planning across more than 26,000 streets in London.” [More]

A new study published in the Journal of the American Medical Directors Association looked at a longitudinal treatment effect analysis of antipsychotics on the behavior of residents in long-term care. “Our study was focused on the use of advanced statistical methods to evaluate the effects of antipsychotic use among nursing home residents who do not have existing conditions associated with psychosis,” study author, Dr. John Hirdes told us. Dr. Hirdes is a professor in the School of Public Health Sciences. “These drugs are often use ‘off label’ to manage behaviours in persons with dementia. We wanted to determine whether these drugs would be effective in managing behaviour problems in long-term care.” [More]

A new study published in Environmental Health Perspectives looked at the combined exposure to folate and lead during pregnancy and autistic-like behaviors among Canadian children from the Maternal-Infant Research on Environmental Chemicals (MIREC) Pregnancy and Birth Cohort. “Our study assessed whether the relationship between blood-lead concentrations during pregnancy and childhood autistic behaviours could be mitigated by folate concentrations or folic acid supplementation,” study author Joshua D. Alampi told us. “We hypothesized that the relationship between lead and autistic behaviours would be stronger among study participants with low folic acid supplementation and lower plasma-folate concentrations.” [More]

A new study published in the Journal of Child Development looked at autobiographical memory for the COVID-19 pandemic lockdowns, psychological adjustment, and their relation over time. “We were interested in getting some insight on how children and adolescents thought about and remembered their lockdown experiences,” study author Dr. Tirill Fiellhaugen Hjuler from the Department of Child and Adolescent Psychiatry at the Aarhus University Hospital told us.
