Immediacy is one of the necessary criteria to show strong evidence of treatment effect in single case experimental designs (SCEDs). With the exception of Natesan and Hedges (2017) no inferential statistical tool has been used to demonstrate or quantify it until now. We investigate and quantify immediacy by treating the change-points between the…

Establishing causal links when experiments are not feasible is an important challenge for psychology researchers. The question of whether parents' spanking causes children's externalizing behavior problems poses such a challenge because randomized experiments of spanking are unethical, and correlational studies cannot rule out potential selection…

Positioning our analyses within two theoretical frameworks, system justification (SJ) theory and critical consciousness (CC), we examine relationships between social class and endorsement of SJ and CC beliefs and behaviors within a sample of low-income, Latinx and Black youth living in Chicago.
