Scarcity acts as a mental burden that disrupts how people process information and make decisions (Mullainathan and Shafir in Scarcity: Why having too little means so much. Macmillan, Basingstoke, 2013; Mani et al. Science 342:976–980, 2013). In this study, we replicated Mani et al.’s (Science 342:976–980, 2013) experimental design to explore whether scarcity also taxes Colombian high school students’ mental bandwidth. In a lab-in-the-field experiment, we tested how 417 high school students from high and low socioeconomic status (SES) in Bogotá, (...) Colombia, responded to different scarcity situations. Students were first presented with hypothetical scenarios of harsh or soft scarcity. Next, participants had to solve a series of tasks that measured higher cognitive functions (i.e. Raven’s Progressive Matrices, Cognitive Reflection Task and questions to assess their Delay Discounting value) and had to explain how they would solve the scarcity situation. As opposed to Mani et al. (Science 342:976–980, 2013), we did not find that scarcity taxed individuals’ mental bandwidth, neither their cognitive nor executive functions. We found that low-SES individuals, under the harsh scarcity condition, displayed more empathic attributes than high-SES individuals. Taken together, the results of this study show the importance of replication in different cultures and environments. (shrink)

We present a hierarchical integrated model of self-regulation in which executive function is the cognitive component of the model, together with emotional, behavioral, physiological, and genetic components. These five components in the model are reciprocally and recursively related. The model is supported by empirical evidence, primarily from a single longitudinal study with good measurement at each level of the model. We also find that the model is consistent with current thinking on related topics such as cybernetic theory, the theory of (...) allostasis and allostatic load, and the theory of skill development in harsh and unpredictable environments, referred to as “hidden talents.” Next, we present literature that the integrative processes are susceptible to environmental adversity, poverty-related risk in particular, while positive social interactions with caregivers would promote self-regulatory processes or mitigate the adverse effect of early risk on the processes. A hierarchical integrative model of self-regulation advances our understanding of self-regulatory processes. Future research may consider broader social contexts of the integrative self-regulation system, such as neighborhood/community contexts and structural racism. This can be an integral step to provide children with equitable opportunities to thrive, even among children living in socioeconomically and psychosocially disadvantaged environments. (shrink)
