Addressing head injury risk in youth football: are heading guidelines the answer?

Background: Recent findings of neurodegenerative pathology in former professional football players have once again called into question the role that "heading", a fundamental aspect of the game, plays in the onset of neurological disease. By introducing guidelines aimed at limiting heading among youth players, the United Kingdom recently joined the United States as the only two nations yet to implement heading regulation in response to growing concerns surrounding football's head injury burden.

Purpose: Evaluating the efficacy of risk mitigation strategies requires the continual reviewal of available evidence, however, youth heading guidelines have yet to undergo such an empirical evaluation.

Public faith in science in the United States through the early months of the COVID-19 pandemic.

Objectives: Given the centrality of science over the course of the COVID-19 crisis, we evaluate changes in people's beliefs in the power of science in the United States over the first four months of the pandemic.

Study Design: Post-hoc analysis of cross-sectional survey data.

Methods: A convenience sample of 1327 participants was recruited through Amazon's Mechanical Turk service for three surveys carried out in 14-25 January, 27 March to 1 April, and 28-29 May of 2020.

Examining a domain-specific link between perceived control and conspiracy beliefs: a brief report in the context of COVID-19.

Unlabelled: Although anecdotal evidence suggests that control-threatening situations are associated with an increase in conspiracy beliefs, existing research does not support this "compensatory control" hypothesis. In the current study, we test a more refined hypothesis: that the link between control threat and conspiracy beliefs is , such that perceived control in a particular domain should lead to conspiracy beliefs pertaining to that domain only. Moreover, given that conspiracy beliefs are stigmatized (i.

The construction of awe in science communication.

Awe is a frequently represented and commonly experienced emotion in science communication. According to a popular account of this emotion, awe is an innate and universal human affective experience that occurs when a person evaluates a target as vast, forcing a shift in their worldview. This shift is portrayed in science communication as resulting in an enhanced interest in the scientific material at hand.

Does Perceived Lack of Control Lead to Conspiracy Theory Beliefs? Findings from an online MTurk sample.

It is widely believed that conspiracy theory beliefs are the product of perceived lack of control. However, to date there is mixed evidence, at best, to support this claim. We consider the reasons why conspiracy theory beliefs do not appear to be based in any straightforward way on control beliefs, interrogating existing findings and presenting new data that call the relationship into question.

"Princess Alice is watching you": children's belief in an invisible person inhibits cheating.

Two child groups (5-6 and 8-9 years of age) participated in a challenging rule-following task while they were (a) told that they were in the presence of a watchful invisible person ("Princess Alice"), (b) observed by a real adult, or (c) unsupervised. Children were covertly videotaped performing the task in the experimenter's absence. Older children had an easier time at following the rules but engaged in equal levels of purposeful cheating as the younger children.

Children's Tattling: the reporting of everyday norm violations in preschool settings.

Tattling, defined as the reporting to a second party of norm violations committed by a third party, is a frequent but little-studied activity among young children. Participant observation and quantitative sampling are used to provide a detailed characterization of tattling in 2 preschools (initial mean age = 4.08 years, N = 40).

The folk psychology of souls.

The present article examines how people's belief in an afterlife, as well as closely related supernatural beliefs, may open an empirical backdoor to our understanding of the evolution of human social cognition. Recent findings and logic from the cognitive sciences contribute to a novel theory of existential psychology, one that is grounded in the tenets of Darwinian natural selection. Many of the predominant questions of existential psychology strike at the heart of cognitive science.

Children's attributions of intentions to an invisible agent.

Children ages 3-9 years were informed that an invisible agent (Princess Alice) would help them play a forced-choice game by "telling them, somehow, when they chose the wrong box," whereas a matched control group of children were not given this supernatural prime. On 2 unexpected event trials, an experimenter triggered a simulated unexpected event (i.e.

Reasoning about dead agents reveals possible adaptive trends.

We investigated whether (a) people positively reevaluate the characters of recently dead others and (b) supernatural primes concerning an ambient dead agent serve to curb selfish intentions. In Study 1, participants made trait attributions to three strangers depicted in photographs; one week later, they returned to do the same but were informed that one of the strangers had died over the weekend. Participants rated the decedent target more favorably after learning of his death whereas ratings for the control targets remained unchanged between sessions.

The development of afterlife beliefs in religiously and secularly schooled children.

Children aged from 4;10 to 12;9 attending either a Catholic school or a public, secular school in an eastern Spanish city observed a puppet show in which a mouse was eaten by an alligator. Children were then asked questions about the dead mouse's biological and psychological functioning. The pattern of results generally replicated that obtained earlier in an American sample, with older children being more apt to state that functions cease after death than younger children (11- to 12-year-olds > 8- to 9-year-olds > 5- to 6-year-olds), and all children being more likely to attribute epistemic, desire, and emotion states to the dead mouse than biological, psychobiological, and perceptual states.

A critical review of the "enculturation hypothesis": the effects of human rearing on great ape social cognition.

Numerous investigators have argued that early ontogenetic immersion in sociocultural environments facilitates cognitive developmental change in human-reared great apes more characteristic of Homo sapiens than of their own species. Such revamping of core, species-typical psychological systems might be manifest, according to this argument, in the emergence of mental representational competencies, a set of social cognitive skills theoretically consigned to humans alone. Human-reared great apes' capacity to engage in "true imitation," in which both the means and ends of demonstrated actions are reproduced with fairly high rates of fidelity, and laboratory great apes' failure to do so, has frequently been interpreted as reflecting an emergent understanding of intentionality in the former.

The natural emergence of reasoning about the afterlife as a developmental regularity.

Participants were interviewed about the biological and psychological functioning of a dead agent. In Experiment 1, even 4- to 6-year-olds stated that biological processes ceased at death, although this trend was more apparent among 6- to 8-year-olds. In Experiment 2, 4- to 12-year-olds were asked about psychological functioning.

The generalization of deferred imitation in enculturated chimpanzees (Pan troglodytes).

Deferred imitation of object-related actions and generalization of imitation to similar but not identical tasks was assessed in three human-reared (enculturated) chimpanzees, ranging in age from 5 to 9 years. Each ape displayed high levels of deferred imitation and only slightly lower levels of generalization of imitation. The youngest two chimpanzees were more apt to generalize the model's actions when they had displayed portions of the target behaviors at baseline, consistent with the idea that learning is more likely to occur when working within the "zone of proximal development.
