"Goldilocks" effect seen in infant response to visual stimuli
Infants avoid spending time examining stimuli that are either too simple or too complex, focusing instead on events with an intermediate level of complexity, according to a new study.
Infants avoid spending time examining stimuli that are either too simple or too complex, focusing instead on events with an intermediate level of complexity, according to a new study.
Researchers conducted 2 experiments with infants aged 7 and 8 months to measure their visual attention to sequences of events of varying complexity.
In each experiment, infants were presented with displays featuring uniquely colored and patterned boxes that were animated to reveal familiar objects. The animated sequences of events continued until the infant looked away continuously for 1 second or until the sequence timed out at 60 seconds.
The findings suggest that infants implicitly seek to maintain intermediate rates of information absorption and avoid wasting cognitive resources on events that are either too simple or too complex.

The benefits of concurrent fetal and maternal heart rate monitoring
April 17th 2024A recent study revealed that employing maternal heart rate monitoring alongside fetal heart rate monitoring during labor significantly decreases the incidence of neonatal encephalopathy and severe neonatal acidemia.
Stress ulcer prophylaxis does not provide prevention of gastrointestinal bleeding in neonates
December 4th 2023In a poster abstract presented at the American Society of Health-System Pharmacists Midyear Clinical Meeting & Exhibition held in Anaheim, California, stress ulcer prophylaxis (SUP) did not appear to provide benefit for prevention of gastrointestinal bleeding and did not increase SUP-associated adverse effects.
