Whereas classic work in judgment and decision making has focused on the deviation of intuition from rationality, more recent research has focused on the performance of intuition in real-world environments. Borrowing from both approaches, we investigate to which extent competing models of intuitive probabilistic decision making overlap with choices according to the axioms of probability theory and how accurate those models can be expected to perform in real-world environments. Specifically, we assessed to which extent heuristics, models implementing weighted additive information (...) integration (WADD), and the parallel constraint satisfaction (PCS) network model approximate the Bayesian solution and how often they lead to correct decisions in a probabilistic decision task. PCS and WADD outperform simple heuristics on both criteria with an approximation of 88.8% and a performance of 73.7%. Results are discussed in the light of selection of intuitive processes by reinforcement learning. (shrink)

In his study “Facial Expression Theory from Romanticism to the Present,” Alan Richardson reminds us that “successful social communication” would be greatly impoverished if “we did not have a reasonably reliable and speedy, and therefore largely unconscious, cognitive mechanism for gauging the emotions and intentions of others through reading their faces.”1 This innately sympathetic capacity for “mind-reading”—that is, for interpreting others’ facial expressions as indicative of internal states of mind—is historically termed “Theory of Mind” (ToM) by cognitive psychologists, philosophers, and (...) primatologists.2Notably, discussion of ToM has mostly revolved around the question of successful or failed empathy, with ..

This article examines baby farming as an urban neighborhood-based system of group child care in Philadelphia in the late nineteenth century and considers the dangers and abuses the practice of baby farming posed for parents, children, and baby farmers. It explores reformers' early efforts to regulate the city's baby farms. Finally, the essay also investigates the ways in which the residents of Philadelphia's poor neighborhoods monitored the child-care establishments in their communities that catered to working mothers.
