The Rat Park study, led by Bruce K. Alexander and colleagues, challenged traditional views on addiction by creating a more natural environment for rats. The study suggested that social and cultural isolation, rather than the inherent addictiveness of drugs, played a crucial role in addiction.

The Still Face Experiment

In 1975, Edward Tronick and his team introduced the “Still Face Experiment" at the biennial meeting of the Society for Research in Child Development. They observed a phenomenon where an infant, following three minutes of interaction with a non-responsive and expressionless mother, quickly becomes solemn and cautious. The infant repeatedly tries to restore the usual reciprocal interaction pattern, but when unsuccessful, withdraws. The infant then turns his face and body away from the mother, displaying a withdrawn and hopeless facial expression. This discovery continues to be one of the most widely confirmed findings in the field of developmental psychology.
