The present article discusses the emergence and dynamics of community resilience by empirically investigating the case of the favela of Paraisópolis in São Paulo, Brazil. The emergence of innovative practices that initially contributed to significantly lower rates of COVID-19 infection and mortality when compared to the city average is described. The analytical framework combines two conceptual perspectives in the study of complex systems. First, resilience in socio-ecological systems highlights the adaptation processes characterized by an interplay of previous experience and emerging new knowledge. Second, the metacontingency framework describes the interplay between a cultural milieu, as a context for cultural practices; an aggregate product; and a selecting environment that embed the acquisition and continuity of interlocking behavioral contingencies. Research methods that combine elements of the descriptive analysis and an exploratory basic qualitative study are employed to understand how the community has self-organized during this period. The findings demonstrate how previous experience with social challenges facilitated self-organization and the emergence of innovative practices in the context of uncoordinated public health measures during the pandemic in Brazil. Furthermore, findings from interviews indicate the existence of positive feedback loops at the community level that facilitated the emergence of innovative practices. This study aims at contributing to the understanding of community resilience by identifying the geographic, psychological, and ecological factors (contextual variables) that facilitate responses to the pandemic.

Coordinated responses of 5 dyads of rats were investigated under fixed‐ratio (FR) schedules of mutual water reinforcement. Coordinated responding was defined as 2 consecutive lever‐presses, 1 from each of 2 rats, occurring <.5 s apart. In the FR schedules, each coordinated episode was defined as 1 response in the FR sequence. The size of FR schedules was parametrically manipulated assuming the values of FR 1, 6, 12, 18, 24, 30, 50, and 9, in this order. Each FR remained in effect until responding reached stability. Under all conditions, pairs of rats received access to water simultaneously (mutual reinforcement). Rates and proportions of coordinated responding showed a bitonic inverted U‐shaped function of ratio size. Postreinforcement pauses increased systematically as the interreinforcement interval increased. Local rates and proportions increased as a function of response location within ratios. Results of a control condition with relaxed temporal constraints for mutual reinforcement showed decreases in rates and proportion of coordinated responses, suggesting that the coordinated responses were controlled by the mutual reinforcement contingencies. The present experiment showed that coordinated responding is quantitatively affected by 3 properties of FR schedules: response requirement, reinforcement rates, and proximity to reinforcement.

Until pharmacological measures are effective at containing the COVID-19 outbreak, adopting protective behaviors is paramount. In this work, we aim at informing interventions to limit the spread of the contagion and prepare against any future outbreaks by developing a behavioral framework to interpret and prescribe both the individual and large-scale uptake of non-pharmaceutical measures. First, we analyze the barriers and facilitators to adherence to protective behaviors according to a three-term contingency by exploring potential gaps in terms of setting stimuli, motivating operations, delayed consequences, and positive or negative consequences. We explore their roles in the likelihood of individual compliance to protective behaviors, taking physical distancing as an example of functional analysis. Second, we interpret contagion control as the cumulative effect of large-scale adherence to protective behaviors. We explore the interrelations between societal problems caused or amplified by similar behaviors presented by many individuals and the coordination of agents or agencies aiming at promoting large-scale behavioral change. Then, we highlight the potential of developing a behavioral vaccine, and practical steps for applying it to promote sustainable cultural change that may protect against health, social, and economic losses in future outbreaks.

The present study compared the effects of reinforcement or punishment versus no additional consequences for instruction following on instructional control and subsequent rule‐governed insensitivity. In two experiments, adult participants were presented with repeated choices between a short progressive‐time schedule and either a fixed time‐schedule or a longer progressive‐time schedule. In Experiment 1, three groups were given an initially accurate instruction relative to the direct contingency. A control group experienced no additional consequences for compliance with instructions, whereas compliance resulted in additional points for a second group, and noncompliance led to the subtraction of points for a third group. In a subsequent phase, instructions became inaccurate and there were no additional consequences for compliance or noncompliance for any group. Consistent with previous results, rule‐governed insensitivity was observed in all participants. Experiment 2 employed the same procedure, except instructions were inaccurate throughout all sessions, and compliance in the subsequent phase resulted in diminishing points per session. Reinforcement for following instructions increased instructional control and subsequent rule‐governed insensitivity. This increase was maintained even after the termination of additional consequences, a result that supports theoretical suggestions that a history of reinforcement for complying with instructions and rules is an important factor in rule‐governed insensitivity.
