Social networking sites such as Facebook attract millions of users by offering highly interactive social communications. Recently, a counter movement has formed, deciding to leave networks quitting their accounts (i.e., virtual identity suicide). To investigate whether quitters (n=310) differ from (n=321), we examined privacy concerns, Internet addiction scores, and personality. We found be significantly more cautious about privacy, having higher being conscientious than users. The main...
Inferring the evolutionary history of cognitive abilities requires large and diverse samples. However, such samples are often beyond reach individual researchers or institutions, studies limited to small numbers species. Consequently, methodological site-specific-differences across can limit comparisons between Here we introduce ManyPrimates project, which addresses these challenges by providing a large-scale collaborative framework for comparative in primate cognition. To demonstrate...
For any scientific report, repeating the original analyses upon data should yield outcomes. We evaluated analytic reproducibility in 25 Psychological Science articles awarded open badges between 2014 and 2015. Initially, 16 (64%, 95% confidence interval [43,81]) contained at least one 'major numerical discrepancy' (>10% difference) prompting us to request input from authors. Ultimately, target values were reproducible without author involvement for 9 (36% [20,59]) articles; with 6 (24%...
Recent evidence suggests that great apes can use the former location of an entity to communicate about it. In this study we built on these findings investigate social-cognitive foundations apes' communicative abilities. We tested whether (n = 35) would adjust their requests for absent entities previous interactions they had with interlocutor. manipulated experience respect interlocutor's knowledge content now-empty as well competence provide additional food items. found adjusted both aspects...
Evidence suggests that great apes engage in metacognitive information seeking for food items. To support the claim a domain-general cognitive process underlies ape metacognition one needs to show selective extends non-food In this study, chimpanzees (Pan troglodytes) and orangutans (Pongo abelii) either had determine location of desired item or property (length tool). We manipulated whether subjects received prior about item's property. During test, opportunity seek respective information....
Abstract Language and other forms of communication are inherently ambiguous therefore require some form common ground to specify the intended meanings utterances. Theoretical accounts usually focus on interactions between adults consider recursive mindreading a prerequisite establishing ground. Contrasting these accounts, in this article, we offer developmental perspective We propose that instead using mindreading, infants rely initially expectation communicative partners act rationally...
Language is a fundamentally social endeavor. Pragmatics the study of how speakers and listeners use reasoning to go beyond literal meanings words interpret language in context. In this article, we take pragmatic perspective on development argue for developmental continuity between early nonverbal communication, learning, linguistic pragmatics. We link phenomena from these different literatures by relating them computational framework (the rational speech act framework), which conceptualizes...
Measuring eye movements remotely via the participant's webcam promises to be an attractive methodological addition in-person eye-tracking in lab. However, there is a lack of systematic research comparing remote web-based with in-lab young children. We report multi-lab study that compared these two measures anticipatory looking task toddlers using WebGazer.js and jsPsych. Results our tested sample 18-27-month-old (N = 125) revealed successfully captured goal-based action predictions, although...
Cooperative problem solving has gained a lot of attention over the past two decades, but range species studied is still small. This limits possibility understanding evolution socio-cognitive underpinnings cooperation. Lutrinae show significant variations in socio-ecology, their cognitive abilities are not well studied. In first experimental study otter social cognition, we presented species-giant otters and Asian small-clawed otters-with cooperative problem-solving task. The loose string...

Pragmatic inferences are an integral part of language learn- ing and comprehension. To recover the intended meaning utterance, listeners need to balance integrate different sources contextual information. In a series experiments, we studied how general expectations about speakers with specific their interactional his- tory particular speaker. We used Bayesian pragmatics model formalize integration process. Experiments 1 2, replicated previous findings showing that make based on...
How the world’s 6,000+ natural languages have arisen is mostly unknown. Yet, new sign emerged recently among deaf people brought together in a community, offering insights into dynamics of language evolution. However, documenting emergence these has consisted studying end product; process by which ad hoc signs are transformed structured communication system not been directly observed. Here we show how young children create systems that exhibit core features less than 30 min. In controlled...
The field of primate cognition studies how primates, including humans, perceive, process, store, retrieve, and use information to guide decision making other behavior. Much this research is motivated by a desire understand these abilities evolved. Large diverse samples from wide range species are vital achieving goal. In reality, however, suffers small sample sizes often limited handful species, which constrains the evolutionary inferences we can draw. We conducted systematic review...
Cumulative cultural learning has been argued to rely on high-fidelity copying of other individuals’ actions. Iconic gestures actions have no physical effect objects in the world but merely represent that would an effect. Learning from iconic thus requires paying close attention teacher’s precise bodily movements—a prerequisite for copying. In three studies, we investigated whether 2- and 3-year-old children ( N = 122) great apes 36) learn novel skills gestures. When faced with a apparatus,...
Theoretical accounts assume that key features of human social cognition are universal. Here we focus on gaze-following, the bedrock interactions and coordinated activities, to test this claim. In comprehensive cross-cultural study spanning five continents 17 distinct cultural communities, examined development gaze-following in early childhood. We identified processing signatures through a computational model assumes participants follow an individual’s gaze by estimating vector emanating from...
Pragmatic inferences are based on assumptions about how speakers communicate: taken to be cooperative and rational; they consider alternatives make intentional choices produce maximally informative utterances. In principle, this analysis applies linguistic but also non-linguistic communicative actions, prediction is typically only tested in children not more systematic implicature contexts. We test key implications of view across six online experiments with American English speaking adults...
<title>Abstract</title> This study investigates children’s narrative skills, using the Multilingual Assessment Instrument for Narratives (MAIN), a theory-based tool adapted to 100 languages. How do overall including use of factual and inferred components, development complete episodes, differ across languages between monolinguals bilinguals? To answer this, we examined 2608 comparable fictional narratives 1189 monolingual bilingual children aged 3-13 years, speaking 33 Children told or...
Cross-cultural studies are crucial for investigating the cultural variability and universality of cognitive developmental processes. However, cross-cultural assessment tools in cognition across languages communities limited. In this article, we describe a gaze-following task designed to measure basic social individuals, ages, (the Task Assessing iNdividual differences Gaze understanding-Open-Cross-Cultural; TANGO-CC). The was developed psychometrically assessed one setting and, with input...
Abstract Parent report measures have proven to be a valuable research tool for studying early language development. Caregivers are given list of words and asked which them their child has already used. However, most available not suited children beyond infancy, come with substantial licensing costs or lack clear psychometric foundation. Here, we present the PREVIC (Parent Report Expressive Vocabulary in Children), an open-access, high-quality vocabulary checklist German-speaking between 3 8...

Adults hold beliefs about children’s developmental timelines and intuitively adjust their moral evaluations based on ages, attributing varying degrees of responsibility depending the context. A common assumption is that limited control explains reduced --- but do adults' factual align with judgments? In three online vignette studies UK US adults (N = 481), participants assessed likelihood blameworthy behaviors in characters aged 2 to 40 years judged when these were explicitly attributed a...
