RESUMO
We report five studies that examine preferences for the allocation of environmental harms and benefits. In all studies, participants were presented with scenarios in which an existing environmental inequality between two otherwise similar communities could either be decreased or increased through various allocation decisions. Our results demonstrate that despite well-established preferences toward equal outcomes, people express weaker preferences for options that increase equality when considering the allocation of environmental harms (e.g., building new polluting facilities) than when considering the allocation of environmental benefits (e.g., applying pollution-reducing technologies). We argue that this effect emerges from fairness considerations rooted in a psychological incompatibility between the allocation of harms, which is seen as an inherently unfair action, and equality, which is a basic fairness principle. Since the allocation of harms is an inevitable part of operations of both governments and businesses, our results suggest that where possible, parties interested in increasing environmental equality may benefit from framing such proposals as bestowing relative benefits instead of imposing relative harms.

Women are underrepresented in fields in which success is believed to require brilliance, but the reasons for this pattern are poorly understood. We investigated perceptions of a "masculinity-contest culture," an organizational environment of ruthless competition, as a key mechanism whereby a perceived emphasis on brilliance discourages female participation. Across three preregistered correlational and experimental studies involving adult lay participants online (N = 870) and academics from more than 30 disciplines (N = 1,347), we found a positive association between the perception that a field or an organization values brilliance and the perception that this field or organization is characterized by a masculinity-contest culture. This association was particularly strong among women. In turn, perceiving a masculinity-contest culture predicted lower interest and sense of belonging as well as stronger impostor feelings. Experimentally reducing the perception of a masculinity-contest culture eliminated gender gaps in interest and belonging in a brilliance-oriented organization, suggesting possible avenues for intervention.

BACKGROUND: In the United States, hemodialysis (HD) is generally performed via a bicarbonate dialysate. It is not known if small amounts of acid used in dialysate to buffer the bicarbonate can meaningfully contribute to overall buffering administered during HD. We aimed to investigate the metabolism of acetate with use of two different acid buffer concentrates and determine if it effects blood bicarbonate concentrations in HD patients. METHODS: The Acid-Base Composition with use of hemoDialysates (ABChD) trial was a Phase IV, prospective, single blind, randomized, cross-over, 2 week investigation of peridialytic dynamics of acetate and bicarbonate associated with use of acid buffer concentrates. Eleven prevalent HD patients participated from November 2014 to February 2015. Patients received two HD treatments, with NaturaLyte® and GranuFlo® acid concentrates containing 4 and 8 mEq/L of acetate, respectively. Dialysate order was chosen in a random fashion. The endpoint was to characterize the dynamics of acetate received and metabolized during hemodialysis, and how it effects overall bicarbonate concentrations in the blood and dialysate. Acetate and bicarbonate concentrations were assessed before, at 8 time points during, and 6 time points after the completion of HD. RESULTS: Data from 20 HD treatments for 11 patients (10 NaturaLyte® and 10 GranuFlo®) was analyzed. Cumulative trajectories of arterialized acetate were unique between NaturaLyte® and GranuFlo® (p = 0.003), yet individual time points demonstrated overlap without remarkable differences. Arterialized and venous blood bicarbonate concentrations were similar at HD initiation, but by 240 min into dialysis, mean arterialized bicarbonate concentrations were 30.2 (SD ± 4.16) mEq/L in GranuFlo® and 28.8 (SD ± 4.26) mEq/L in NaturaLyte®. Regardless of acid buffer concentrate, arterial blood bicarbonate was primarily dictated by the prescribed bicarbonate level. Subjects tolerated HD with both acid buffer concentrates without experiencing any related adverse events. CONCLUSIONS: A small fraction of acetate was delivered to HD patients with use of NaturaLyte® and GranuFlo® acid buffers; the majority of acetate received was observed to be rapidly metabolized and cleared from the circulation. Blood bicarbonate concentrations appear to be determined mainly by the prescribed concentration of bicarbonate. TRIAL REGISTRATION: This trial was registered on ClinicalTrials.gov on 11 Dec 2014 ( NCT02334267 ).

Contagion is a form of magical thinking in which people believe that a person's immaterial qualities or essence can be transferred to an object through physical contact. Here we investigate how a belief in contagion influences the sale of celebrity memorabilia. Using data from three high-profile estate auctions, we find that people's expectations about the amount of physical contact between the object and the celebrity positively predicts the final bids for items that belonged to well-liked individuals (e.g., John F. Kennedy) and negatively predicts final bids for items that belonged to disliked individuals (e.g., Bernard Madoff). A follow-up experiment further suggests that these effects are driven by contagion beliefs: when asked to bid on a sweater owned by a well-liked celebrity, participants report that they would pay substantially less if it was sterilized before they received it. However, sterilization increases the amount they would pay for a sweater owned by a disliked celebrity. These studies suggest that magical thinking may still have effects in contemporary Western societies and they provide some unique demonstrations of contagion effects on real-world purchase decisions.

In four experiments, we found that the presence of self-interest in the charitable domain was seen as tainting: People evaluated efforts that realized both charitable and personal benefits as worse than analogous behaviors that produced no charitable benefit. This tainted-altruism effect was observed in a variety of contexts and extended to both moral evaluations of other agents and participants' own behavioral intentions (e.g., reported willingness to hire someone or purchase a company's products). This effect did not seem to be driven by expectations that profits would be realized at the direct cost of charitable benefits, or the explicit use of charity as a means to an end. Rather, we found that it was related to the accessibility of different counterfactuals: When someone was charitable for self-interested reasons, people considered his or her behavior in the absence of self-interest, ultimately concluding that the person did not behave as altruistically as he or she could have. However, when someone was only selfish, people did not spontaneously consider whether the person could have been more altruistic.

Recent experimental evidence indicates that intuitions about inherence and system justification are distinct psychological processes, and that the inherence heuristic supplies important explanatory frameworks that are accepted or rejected based on their consistency with one's motivation to justify the system.

In six studies, we find evidence of efficiency neglect: when thinking about the effects of population growth, people intuitively focus on increased demand while neglecting the changes in production efficiency that occur alongside, and often in response to, increased demand. In other words, people tend to think of others solely as consumers, rather than as consumers as well as producers. Efficiency neglect leads to beliefs that the real costs of some consumer goods are rising when they are actually decreasing and may contribute to antiimmigration sentiments because of the fear that increasing local population creates competition for fixed resources. We demonstrate that economic pessimism and antiimmigration sentiments are reduced when people are prompted to consider their own beliefs about increased productivity over time, but are unchanged when they consider their beliefs about increases in demand. Together, these findings shed light on people's lay economic theories and suggest promising interventions. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

The world around us presents two fundamentally different forms of patterns: those that appear random and those that appear ordered. As adults we appreciate that these two types of patterns tend to arise from very different sorts of causal processes. Typically, we expect that, whereas agents can increase the orderliness of a system, inanimate objects can cause only increased disorder. Thus, one major division in the world of causal entities is between those that are capable of "reversing local entropy" and those that are not. In the present studies we find that sensitivity to the unique link between agents and order emerges quite early in development. Results from three experiments suggest that by 12 mo of age infants associate agents with the creation of order and inanimate objects with the creation of disorder. Such expectations appear to be robust into children's preschool years and are hypothesized to result from a more general understanding that agents causally intervene on the world in fundamentally different ways from inanimate objects.

Bullot & Reber (B&R) make a strong case for the role of causal reasoning in the appreciation of artwork. Although I agree that an artistic design stance is important for art appreciation, I suggest that it is a subset of a more general framework for evaluating artworks as the causal extensions of individuals, which includes inferences about the creator's mind, as well as more physical notions of essence.

Psychological essentialism has played an important role in social psychology, informing influential theories of stereotyping and prejudice as well as questions about wrongdoers' accountability and their ability to change. In the existing literature, essentialism is often tied to beliefs in shared biology-that is, the extent to which members of a social group are seen as having the same underlying biological features. Here we investigate the possibility of "value-based essentialism" in which people think of certain social groups in terms of an underlying essence, but that essence is understood as a value. Study 1 explored beliefs about a wide range of social groups and found that both groups with shared biology (e.g., women) and shared values (e.g., hippies) elicited similar general essentialist beliefs relative to more incidental social categories (e.g., English-speakers). In Studies 2-4, participants who read about a group either as being based in biology or in values reported higher general essentialist beliefs compared with a control condition. Because biological essences about social groups have been connected to a number of downstream consequences, we also investigated two test cases concerning value-based essentialism. In Study 3, beliefs about both shared biology and shared values increased inductive generalizations about the social group relative to control, but in Study 4, only the shared biology condition reduced blame for wrongdoing. Together these findings join with recent work to support a broader theoretical framework of essentialism about social groups that can be arrived at through multiple pathways, including, in the present case, shared values.

RESUMO
Psychologists have long been captivated by the perception of animacy - the fact that even simple moving shapes may appear to engage in animate, intentional, and goal-directed movements. Here we report several new types of studies of a particularly salient form of perceived animacy: chasing, in which one shape (the 'wolf') pursues another shape ('the sheep'). We first demonstrate two new cues to perceived chasing -chasing subtlety (the degree to which the wolf deviates from perfectly 'heat-seeking' pursuit) and directionality (whether and how the shapes 'face' each other). We then use these cues to show how it is possible to assess the objective accuracy of such percepts, and to distinguish the immediate perception of chasing from those more subtle (but nevertheless real) types of 'stalking' that cannot be readily perceived. We also report several methodological advances. Previous studies of the perception of animacy have faced two major challenges: (a) it is difficult to measure perceived animacy with quantitative precision; and (b) task demands make it difficult to distinguish perception from higher-level inferences about animacy. We show how these challenges can be met, at least in our case study of perceived chasing, via tasks based on dynamic visual search (the Find-the-Chase task) and a new type of interactive display (the Don't-Get-Caught! task).

In this study, we tested whether 8-month-old infants could infer an actor's unfulfilled goal, despite some physical information present in the displays being inconsistent with the attempted goal. Infants saw a human hand holding a ring repeatedly approach the top of a plastic cone in an apparent failed attempt to place the ring on the cone. The hand and ring then bounced away from the top of the cone toward the floor. Thus, some information presented was relevant to the goal (the motion toward the goal, the afforded relationship between the ring and the cone, and the repeated attempt), but some of it was irrelevant to the goal (the movement away from the goal). Infants were presented with 2 test events: 1 that was consistent with all the trajectory information but inconsistent with the goal, and 1 that was consistent with the goal. Eight-month-olds looked longer to the trajectory-consistent event, suggesting they were able to infer the goal despite the physical ambiguity. Infants who had not been habituated to the failed attempt or who saw a matched inanimate control did not show this pattern, suggesting that infants in the first year of life actively and selectively analyze the unfulfilled goal-directed behavior of others.
RESUMO
This paper reports the results of two sets of studies demonstrating 14-month-olds' tendency to associate an object's behavior with internal, rather than external features. In Experiment 1 infants were familiarized to two animated cats that each exhibited a different style of self-generated motion. Infants then saw a novel individual that had an internal feature (stomach color) similar to one cat, but an external feature (hat color) similar to the other. Infants looked reliably longer when the individual's motion was congruent with the hat than when it was congruent with the stomach. Using a converging method involving object choice, Experiment 2 found that infants prioritized the internal feature over the external feature only when the object's behavior was self-generated. In the absence of self-generated behaviors, however, infants did not show a preference towards the internal feature.

The currency of our visual experience consists not only of visual features such as color and motion, but also seemingly higher-level features such as causality--as when we see two billiard balls collide, with one causing the other to move. One of the most important and controversial questions about causal perception involves its origin: do we learn to see causality, or does this ability derive in part from innately specified aspects of our cognitive architecture? Such questions are difficult to answer, but can be indirectly addressed via experiments with infants. Here we explore causal perception in 7-month-old infants, using a different approach from previous work. Recent work in adult visual cognition has demonstrated a postdictive aspect to causal perception: in certain situations, we can perceive a collision between two objects in an ambiguous display even after the moment of potential 'impact' has already passed. This illustrates one way in which our conscious perception of the world is not an instantaneous moment-by-moment construction, but rather is formed by integrating information over short temporal windows. Here we demonstrate analogous postdictive processing in infants' causal perception. This result demonstrates that even infants' visual systems process information in temporally extended chunks. Moreover, this work provides a new way of demonstrating causal perception in infants that differs from previous strategies, and is immune to some previous types of critiques.

The present studies investigated children's and adults' intuitive beliefs about the physical nature of essences. Adults and children (ranging in age from 6 to 10 years old) were asked to reason about 2 different ways of determining an unknown object's category: taking a tiny internal sample from any part of the object (distributed view of essence) or taking a sample from one specific region (localized view of essence). Results from 3 studies indicated that adults strongly endorsed the distributed view, and children showed a developmental shift from a localized to distributed view with increasing age. These results suggest that even children go beyond mere placeholder notions of essence, committing to conceptual frameworks of how essences might be physically instantiated.

People sometimes explain behavior by appealing to an essentialist concept of the self, often referred to as the true self. Existing studies suggest that people tend to believe that the true self is morally virtuous; that is deep inside, every person is motivated to behave in morally good ways. Is this belief particular to individuals with optimistic beliefs or people from Western cultures, or does it reflect a widely held cognitive bias in how people understand the self? To address this question, we tested the good true self theory against two potential boundary conditions that are known to elicit different beliefs about the self as a whole. Study 1 tested whether individual differences in misanthropy-the tendency to view humans negatively-predict beliefs about the good true self in an American sample. The results indicate a consistent belief in a good true self, even among individuals who have an explicitly pessimistic view of others. Study 2 compared true self-attributions across cultural groups, by comparing samples from an independent country (USA) and a diverse set of interdependent countries (Russia, Singapore, and Colombia). Results indicated that the direction and magnitude of the effect are comparable across all groups we tested. The belief in a good true self appears robust across groups varying in cultural orientation or misanthropy, suggesting a consistent psychological tendency to view the true self as morally good.

A growing body of research has examined how people judge the persistence of identity over time-that is, how they decide that a particular individual is the same entity from one time to the next. While a great deal of progress has been made in understanding the types of features that people typically consider when making such judgments, to date, existing work has not explored how these judgments may be shaped by normative considerations. The present studies demonstrate that normative beliefs do appear to play an important role in people's beliefs about persistence. Specifically, people are more likely to judge that the identity of a given entity (e.g., a hypothetical nation) remains the same when its features improve (e.g., the nation becomes more egalitarian) than when its features deteriorate (e.g., the nation becomes more discriminatory). Study 1 provides a basic demonstration of this effect. Study 2 shows that this effect is moderated by individual differences in normative beliefs. Study 3 examines the underlying mechanism, which is the belief that, in general, various entities are essentially good. Study 4 directly manipulates beliefs about essence to show that the positivity bias regarding essences is causally responsible for the effect.

The present studies examine how demand for certain types of authentic objects is related to a more fundamental need to form social connections with others. Specifically, Experiment 1 demonstrates that manipulating the need to belong leads to greater valuation of celebrity memorabilia. Experiment 2 provides converging evidence by demonstrating that individual differences in the need to belong moderate the relationship between beliefs in essence transfer (i.e., contagion) and valuation. This paper lends insight into the underlying motives behind demand for authentic objects and, more broadly, reinforces the compensatory role of consumption in satisfying core psychological needs.

Past research has identified a number of asymmetries based on moral judgments. Beliefs about (a) what a person values, (b) whether a person is happy, (c) whether a person has shown weakness of will, and (d) whether a person deserves praise or blame seem to depend critically on whether participants themselves find the agent's behavior to be morally good or bad. To date, however, the origins of these asymmetries remain unknown. The present studies examine whether beliefs about an agent's "true self" explain these observed asymmetries based on moral judgment. Using the identical materials from previous studies in this area, a series of five experiments indicate that people show a general tendency to conclude that deep inside every individual there is a "true self" calling him or her to behave in ways that are morally virtuous. In turn, this belief causes people to hold different intuitions about what the agent values, whether the agent is happy, whether he or she has shown weakness of will, and whether he or she deserves praise or blame. These results not only help to answer important questions about how people attribute various mental states to others; they also contribute to important theoretical debates regarding how moral values may shape our beliefs about phenomena that, on the surface, appear to be decidedly non-moral in nature.

The concept of potential is central to a number of decisions, ranging from organizational hiring, to athletic recruiting, to the evaluation of artistic performances. While potential may often be valued for its future payoffs, the present studies investigate whether people value potential even when making decisions about goods and experiences that can only be consumed in the present. Experiment 1 demonstrates that potential makes people more likely to consume inferior performances in the present. Experiment 2 manipulated temporal focus and demonstrates that focusing on the present (vs. the future) attenuates the effect of potential on enjoyment. Experiment 3 demonstrates that merely moving the performance into the past negates the effect of potential. And, Experiment 4 demonstrates that potential increases valuation only when value is tied to abstract, hedonic dimensions, but not when it is tied to concrete, utilitarian dimensions.
