In the 1960s, Jonathan Freedman designed an experiment around these objects that found subjects responded best to “minimal justification” in the long term. These objects are the typical “transitional objects” defined by D. W. Winnicott. Despite being threatened with more severe punishments for doing (15[1])so, subjects expressed preference for “forbidden” examples (15[1])of these objects in classic studies on cognitive dissonance. These objects were hidden under (*) blankets in a test of object permanence devised (-5[1])by Jean Piaget. These objects were used to demonstrate that children learn social behaviors (10[2]-5[1])through observation in a 1961 study (10[1])that staged adult aggression towards these objects. For 10 points, name these objects whose “Bobo” types featured in an Albert Bandura study. ■END■ (10[1])
