Therefore the three researchers conducted this study “to examine the developmental origins of chunking, using a violation-of-expectation procedure to ask whether 7-month-old infants, whose working memory capacity is still maturing, also can chunk items in memory” (Moher, Tuerk, & Feigenson, 2011). Based on the purpose of the study, the researchers hypothesized that
The theoretical perspective that is being taken into account is the information processing perspective. For experiment 1, the researchers conducted the study on 20 healthy full-term infants from Baltimore, Maryland., who had an average mean age of 7 months and 2 days. The independent variable of the experiment was the number of items that were shown to the child. The dependent variable was then whether or not they believed the outcome or if it was unexpected. With these variables in mind, the researchers had the parents of the children sit out of view behind the infants and were instructed to refrain from interacting with infants. The researchers also played classical music at a low volume throughout the experiment. They conducted both baseline trials and test trials. For the baseline trials, they measured
