The present study investigated the effects of fixed-ratio (FR) and variable-ratio (VR) reinforcement schedules on patterns of cooperative responding in pairs of rats. Experiment 1 arranged FR 1, FR 10, and VR 10 schedules to establish cooperative responding (water delivery depended on the joint responding of two rats). Cooperative response rates and proportions were higher under intermittent schedules than under continuous reinforcement. The FR 10 schedule generated a break-and-run pattern, whereas the VR 10 schedule generated a relatively high and constant rate pattern. Experiment 2 evaluated the effects of parametric manipulations of FR and VR schedules on cooperative responding. Rates and proportions of cooperative responding generally increased between ratio sizes of 1 and 5 but showed no consistent trend as the ratio increased from 5 to 10. Experiment 3 contrasted cooperative responding between an FR6 schedule and a yoked control schedule. Coordinated behavior occurred at a higher rate under the former schedule. The present study showed that external consequences and the schedules under which the delivery of these consequences are based, select patterns of coordinated behavior.

Performance feedback is a managerial practice whose effects widely impact job satisfaction and commitment. Job satisfaction and commitment represent antecedents of organizational citizenship behaviour (OCB), denoting a willingness to cooperate. However, there has been little research on the direct relationship between performance feedback and OCB. Previous works addressed their mediating role, such as organization-based self-esteem, job satisfaction or other measures of discretionary effort. Our search of peer-reviewed studies containing measures of feedback and OCB found 15 studies, containing 21 critically appraised correlation measures. While descriptive findings of the systematic review showed a small correlation, studies that contained measures of feedback frequency were more likely to include higher reports of OCB than studies containing measures of feedback properties. After computing correlation scores to effect sizes, findings from the meta-analysis indicated a small average effect size of performance feedback on OCB (r adj =.27, 95% CI =.21-.33). The discussion addresses the differential effects of positive and negative feedback, frequency, and properties of feedback on reports of OCB levels (by employees and supervisors), as well as further applications for line management.

Grocery stores are important settings to promote healthier food and beverage choices. The present paper aims at reviewing the effectiveness of different types of in-store interventions and how they impact sales of different product category in real grocery stores. Systematic search was conducted in six databases. In-store interventions were categorized according to the framework by Kraak et al. (2017) into one or more of eight interventions (e.g., place, profile, portion, pricing, promotion, healthy default picks, prompting and proximity). This systematic theme-based review follows the preferred reporting items for systematic reviews and meta-analyses (PRISMA) data screening and selection. Thirty-six studies were included in the qualitative synthesis and 30 studies were included in the meta-analysis, representing 72 combinations of in-store interventions. The analysis demonstrates that interventions overall had small significant effect size (ES) using Cohen’s d on food purchase behavior (d = 0.17, 95% CI [0.04, 0.09]), with largest ES for pricing (d = 0.21) and targeting fruits and vegetables (d = 0.28). Analysis of ES of in-store interventions show that pricing, and pricing combined with promotion and prompting, effectively impacted purchase behavior. Interventions significantly impacted both sales of healthy and unhealthy products and significantly increased sales of fruits and vegetables, healthy beverage and total volume of healthy products. Results should however be interpreted with some caution, given the relatively low quality of overall evidence and low number of studies and observations for some types of intervention. Further research exploring impact on different in-store interventions and targeting especially unhealthy products are needed.

In Selection by Consequences, Skinner (1981) described a causal model that explains human behavior as a joint product of three levels of selection: (a) the contingencies of survival involved in natural selection, (b) the contingencies of reinforcement involved in the selection of individual behavior, and (c) contingencies of an evolving social environment. Since then, researchers from behavior analysis and other fields such as biology and anthropology have used an evolutionist/selectionist approach to greatly improve our understanding of those three levels of analysis. As our knowledge of each level has expanded, the borders between them and their belonging to specialized academic domains has become less clear. Even though Skinner (1981, p 502) stated that "each level of variation and selection has its own discipline-the first, biology; the second, psychology; and the third anthropology," we argue that Selection by Consequences sets a milieu for behavior analysis to take part in the analysis of the integrated relation among all levels of analysis. In this commentary to Skinner's (1981) paper, we aim to point out some advances in behavior analysis that may contribute to bridging the gap between the three levels of analysis described by Skinner. In doing so, we will briefly describe some relations between natural and behavioral selection and between behavioral and cultural selection. Additionally, we discuss an alternative model to analyze selection of cultures. Natural-Behavioral SelectionLet us start with the relationship between natural and behavioral selection. Glenn and Madden (1995) pointed to Skinner (1953) andCampbell (1956) as the first to compare the processes of natural selection and reinforcement. Glenn and Madden argued that if the same processes that explain organic selection were applicable to behavioral selection, the understanding of one would provide valuable insights about the other. In organic evolution through natural selection, genes are the units of retention and replication that are transmitted generation-to-generation, enabling species survival and adaptation to environmental changes. On the other hand, in behavioral
