When comparing rates of helping, sharing, and comforting in different situations, studies show that:

a) there is substantial variation across age groupsb) there is variability between experimental tasksc) sometimes children do not help (Dunfield et al., 2011; Dunfield and Kuhlmeier, 2013; Svetlova et al., 2010)

Research on helping, sharing, and comforting behaviors in different situations has revealed that these behaviors are not uniform across all age groups or tasks. This variability suggests that factors such as age, task complexity, and context play a significant role in influencing these behaviors. Additionally, it has been observed that children do not always exhibit helping behaviors, indicating that their responses can be influenced by various factors beyond just their developmental stage.
