Recent work suggests that people predict how objects interact in a manner consistent with Newtonian physics, but with additional uncertainty. However, the sources of uncertainty have not been examined. In this study, we measure perceptual noise in initial conditions and stochasticity in the physical model used to make predictions. Participants predicted the trajectory of a moving object through occluded motion and bounces, and we compared their behavior to an ideal observer model. We found that human judgments cannot be captured by (...) simple heuristics and must incorporate noisy dynamics. Moreover, these judgments are biased consistently with a prior expectation on object destinations, suggesting that people use simple expectations about outcomes to compensate for uncertainty about their physical models.

When asked to identify objects having unique shapes and colors among other objects, English speakers often produce redundant color modifiers (“the red circle”) while Spanish speakers produce them less often (“el circulo (rojo)”). This cross‐linguistic difference has been attributed to a difference in word order between the two languages, under the incremental efficiency hypothesis (Rubio‐Fernández, Mollica, & Jara‐Ettinger, 2020). However, previous studies leave open the possibility that broad language differences between English and Spanish may explain this cross‐linguistic difference such that (...) English speakers may generally produce more modifiers than Spanish speakers, including redundant ones, irrespective of word order. Here, we test the incremental efficiency hypothesis in a language production task crossing language (English, Spanish) with modifier type (color, number). Critically, number words occur on the same side of the noun in both English and Spanish. If broad language differences are responsible for the higher rate of color word production in English compared to Spanish, then the same effect should hold for number words. In contrast, the incremental efficiency hypothesis predicts an interaction between language and modifier type, due to different ordering for color words but identical ordering for number words. Our pre‐registered analyses offer strong support for the incremental efficiency hypothesis, demonstrating how seemingly small differences in language can cause us to describe the world in surprisingly different ways.

A recent consensus statement claimed that double effect can justify induction of labor before viability when life-threatening pathological complications arise from the interaction of a normally functioning placenta with the diseased heart of the mother. The authors of this essay agree. They analyze two pieces published in response, using the framework of the first and fourth criteria of double effect; identify and attempt to clarify inaccuracies and other sources of ambiguity in the discussion; and acknowledge practical implications for other scenarios (...) previously considered illicit. They conclude that more thorough medical and moral discussion is needed regarding the fourth criterion, even if the act itself is not intrinsically evil.

Trailblazing marine biologist, visionary conservationist, deep ecology philosopher, Edward F. Ricketts has reached legendary status in the California mythos. A true polymath and a thinker ahead of his time, Ricketts was a scientist who worked in passionate collaboration with many of his friends—artists, writers, and influential intellectual figures—including, perhaps most famously, John Steinbeck, who once said that Ricketts's mind “had no horizons.” This unprecedented collection, featuring previously unpublished pieces as well as others available for the first time in their (...) original form, reflects the wide scope of Ricketts’s scientific, philosophical, and literary interests during the years he lived and worked on Cannery Row in Monterey, California. These writings, which together illuminate the evolution of Ricketts’s unique, holistic approach to science, include “Verbatim transcription of notes on the Gulf of California trip,” the basic manuscript for Steinbeck’s and Ricketts’s _Log from the Sea of Cortez;_ the essays “The Philosophy of Breaking Through” and “A Spiritual Morphology of Poetry;” several shorter pieces on topics including collecting invertebrates and the impact of modernization on Mexican village life; and more. An engaging critical biography and a number of rare photographs offer a new and richly detailed view of Ricketts’s life. (shrink)

We define self-control as an individual's efforts to bias the outcome of present or anticipated motivational conflicts in order to increase the likelihood that subsequent behavior serves perceived long-term interests. We suggest suppression and resolve are not “mechanisms” that underlie self-control, but rather are classes of strategies that influence motivations in order to increase the likelihood of successful self-control outcomes.

In the 1920s, Ludwig von Mises argued correctly that the problem of making economic calculations without market‐generated prices would be an insuperable difficulty for socialist systems of production. Bryan Caplan is right to argue that there is no theoretical way to infer the magnitude of this difficulty, but he is wrong to insist that the history of poor economic performance displayed by real‐world socialism should be attributed not to the “socialist calculation problem,” but to inadequate work incentives. A state that (...) had solved the calculation problem would have well within its means the solution to the incentives problem, too. (shrink)

God vs. the Gavel challenges the pervasive assumption that all religious conduct deserves constitutional protection. While religious conduct provides many benefits to society, it is not always benign. The thesis of the book is that anyone who harms another person should be governed by the laws that govern everyone else - and truth be told, religion is capable of great harm. This may not sound like a radical proposition, but it has been under assault since the 1960s. The majority of (...) academics and many religious organizations would construct a fortress around religious conduct that would make it extremely difficult to prosecute child abuse by clergy, medical neglect of children by faith-healers, and other socially unacceptable behaviors. This book intends to change the course of the public debate over religion by bringing to the public's attention the tactics of religious entities to avoid the law and therefore harm others. (shrink)

We develop a cultural evolutionary theory of the origins of prosocial religions and apply it to resolve two puzzles in human psychology and cultural history: (1) the rise of large-scale cooperation among strangers and, simultaneously, (2) the spread of prosocial religions in the last 10–12 millennia. We argue that these two developments were importantly linked and mutually energizing. We explain how a package of culturally evolved religious beliefs and practices characterized by increasingly potent, moralizing, supernatural agents, credible displays of faith, (...) and other psychologically active elements conducive to social solidarity promoted high fertility rates and large-scale cooperation with co-religionists, often contributing to success in intergroup competition and conflict. In turn, prosocial religious beliefs and practices spread and aggregated as these successful groups expanded, or were copied by less successful groups. This synthesis is grounded in the idea that although religious beliefs and practices originally arose as nonadaptive by-products of innate cognitive functions, particular cultural variants were then selected for their prosocial effects in a long-term, cultural evolutionary process. This framework (1) reconciles key aspects of the adaptationist and by-product approaches to the origins of religion, (2) explains a variety of empirical observations that have not received adequate attention, and (3) generates novel predictions. Converging lines of evidence drawn from diverse disciplines provide empirical support while at the same time encouraging new research directions and opening up new questions for exploration and debate.

Many science teachers, especially those engaging in the science-technology-society approach, are finding it difficult to deal with issues having a strong ethical component. It would be useful to forecast the variety of positions that may be held by students when dealing with these issues. The Ethics Decision and Analysis Model provides a mechanism for this purpose. Building on the work of Kohlburg, the model identifies four decision-making orientations: a) normative order, b) utility consequences, c) justice/fairness, and d) ideal-self. Issues are (...) analyzed using both the proponent and opponent outlooks in each of the four orientations above within each of the three component areas of science-technology-society. Using this model to analyze issues that are to be presented, and allowing for each, the science teacher is more likely to ensure that students are not left out of discussions or role plays due to their ethical decision-making framework.

Music comprises a diverse category of cognitive phenomena that likely represent both the effects of psychological adaptations that are specific to music (e.g., rhythmic entrainment) and the effects of adaptations for non-musical functions (e.g., auditory scene analysis). How did music evolve? Here, we show that prevailing views on the evolution of music – that music is a byproduct of other evolved faculties, evolved for social bonding, or evolved to signal mate quality – are incomplete or wrong. We argue instead that (...) music evolved as a credible signal in at least two contexts: coalitional interactions and infant care. Specifically, we propose that (1) the production and reception of coordinated, entrained rhythmic displays is a co-evolved system for credibly signaling coalition strength, size, and coordination ability; and (2) the production and reception of infant-directed song is a co-evolved system for credibly signaling parental attention to secondarily altricial infants. These proposals, supported by interdisciplinary evidence, suggest that basic features of music, such as melody and rhythm, result from adaptations in the proper domain of human music. The adaptations provide a foundation for the cultural evolution of music in its actual domain, yielding the diversity of musical forms and musical behaviors found worldwide. (shrink)

In our response to the 27 commentaries, we refine the theoretical claims, clarify several misconceptions of our framework, and explore substantial disagreements. In doing so, we show that our framework accommodates multiple historical scenarios; debate the historical evidence, particularly about “pre-Axial” religions; offer important details about cultural evolutionary theory; clarify the termprosociality;and discuss proximal mechanisms. We review many interesting extensions, amplifications, and qualifications of our approach made by the commentators.

The Farmers Market Nutrition Program (FMNP) is a federal-state partnership designed to provide fresh, locally grown produce to low-income participants at nutritional risk and expand consumer awareness and use of local produce sold at farmers markets. This paper describes the results of a collaboration initiative based on the typology of a “comprehensive, multisectorial collaboration” to support the FMNP. We report the outcomes of the partnerships that developed over three years, including increased outreach to FMNP participants and strategies to decrease barriers (...) to participation. Those partnerships that reached higher degrees of coordination or collaboration are now addressing market accessibility and market quality in new ways. Those partnerships that exhibited the highest degree of collaboration are contributing to community capacity building beyond FMNP issues per se and to larger issues affecting the agriculture community and the food security of residents.

We discuss approaches to the study of the evolution of music (sect. R1); challenges to each of the two theories of the origins of music presented in the companion target articles (sect. R2); future directions for testing them (sect. R3); and priorities for better understanding the nature of music (sect. R4).

The visual world of animals is highly diverse and often very different from the world that we humans take for granted. This book provides an extensive review of the latest behavioral and neurobiological research on animal vision, highlighting fascinating species similarities and differences in visual processing. It contains 26 chapters written by world-leading experts about a variety of species including: honeybees, spiders, fish, birds, and primates. The chapters are divided into six sections: Perceptual grouping and segmentation, Object perception and object (...) recognition, Motion perception, Visual attention, Different dimensions of visual perception, and Evolution of the visual system. An exhaustive work in range and depth, How Animals See the World will be a valuable resource for advanced students and researchers in areas of cognitive psychology, perception and cognitive neuroscience, as well as researchers in the visual sciences.
