From age 3-4, children are generally capable of telling stories about a topic free of choice. Over the years their stories become more sophisticated in content and structure, reflecting various aspects of cognitive development. Here we focus on children’s ability to construe characters with increasing levels of mental depth, arguably reflecting socio-cognitive capacities including Theory of Mind. Within our sample of 51 stories told by children aged 4-10, characters range from flat “actors” performing simple actions, to “agents” having basic perceptive, emotional, and intentional capacities, to fully-blown “persons” with complex inner lives. We argue for the underexplored potential of computationally extracted story-internal factors (e.g. lexical/syntactic complexity) in explaining variance in character depth, as opposed to story-external factors (e.g. age, socioeconomic status) on which existing work has focused. We show that especially lexical richness explains variance in character depth, and this effect is larger than and not moderated by age.

Near-misses sting: As adults, we intuitively understand that someone who just missed a desirable outcome (near-miss) feels worse than someone who missed by a far margin (far-miss). What cognitive capacities support these intuitions, and how do they emerge in early childhood? We presented adults (n=42) and six- to eight-year-olds (n=91; pre-registered) with various near-miss scenarios. We found that (1) adults generally infer that a near-miss character would feel worse than a far-miss character, (2) yet their inferences vary depending on the context, and (3) children show a strikingly different pattern from adults, robustly choosing the far-miss character as feeling worse. The tendency to judge the near-miss character as feeling worse increased with age, but even 8-year-olds were still below chance. These patterns raise the possibility that young children start with a distance-based bias that gradually gets replaced by adult-like inferences that involve counterfactual reasoning.

The question of whether bilingual language experience confers a cognitive advantage remains open. Controversy arises from assertions that putative advantages can instead be explained by differences in culture, socioeconomic class, or immigration status, as well as the classification of bilingual experience as a fixed variable rather than a random effect. The present study addresses these issues by assessing the impact of variability in English (L2) language experience on executive function in a group of Mandarin-English speakers (n = 41) from Shenzhen. Participants reported on demographic details, language history, perceived stress, and performed a Simon task online. Data were analysed using Linear Mixed Effects (LME) models to test for individual differences on Simon task performance. Results showed higher levels of L2 proficiency were associated with reduced Simon effects, suggesting a cognitive advantage.

Children and adults show preferences for native speakers and judge them to be more credible sources of information than non-native speakers. Previous research with children has attributed this bias to a preference for in-group members. The present study investigated the role of processing fluency on children’s social judgements. Children were shown two speakers (one with a native accent and the other with a non-native accent) relaying a message from another individual. They were then asked to make credibility and social judgements about the speakers and their messages. Children were also asked a processing fluency question, and a question about the speakers’ comprehension of the original message. Responses to the processing fluency question and question about the speakers’ comprehension predicted credibility judgements, but did not predict preference. These findings suggest that processing fluency may play a role in developing biases towards non-native accented speakers. Implications are discussed.

In three experiments (total N = 1302) we investigated whether causal proximity affects moral judgments. We manipulated causal proximity by varying the length of chains mediating between actions and outcomes, and by varying the strengths of causal links. We demonstrate that moral judgments are affected by causal proximity with longer chains or weaker links leading to more lenient moral evaluations. Moreover, we identify outcome foreseeability as the crucial factor linking causal proximity and moral judgments. While effects of causal proximity on moral judgments were small when controlling for factors that were confounded in previous studies, knowledge about the presence of causal links substantially alters judgments of permissibility and responsibility. The experiments demonstrate a tight coupling between causal representations, inferences about mental states, and moral reasoning.

A Causal Proximity Effect in Moral Judgment

People sometimes criticize others for feeling sad, especially when they judge that person's sadness to be irrational. According to canonical models of blame, these reactions reflect attributions of control over the negative emotion. However, some scholars have recently suggested that blame reactions towards other's emotions ignore attributions of control, and instead, reflect negative reactions to the emotion itself. We present a study that adjudicates between these two competing views. Our results support control-based models of blame and criticism. We also identify two cues that people rely on when attributing control over emotions; namely, how well calibrated the emotion is to its eliciting circumstances and the sufferer’s capacity to think rationally. In sum: People will criticize others for their emotional suffering when they judge both that the suffering is irrational, and that the sufferer is sufficiently rational to recognize this fact, and so can choose to stop feeling upset.

Why do people criticize others for suffering irrationally?

Research on contrastive category learning has revealed a robust tendency for learners to develop caricaturized representations (elsewhere: ideals or extreme points) to support successful discriminative classification. These representations are defined by extreme values on some task-relevant dimension and are often indicated as highly representative of their categories. Work in this area has elaborated the task constraints and contexts necessary for these representations to emerge, but little research has scrutinized whether caricatured representations extend beyond a category’s known range of feature values. To these ends, across two experiments, we investigated whether the most representative items for a category can extend beyond the training set. Data from pairwise typicality comparisons following learning suggests that caricatured categories may be supported by representations that extend past the feature range present in training. The findings are better explained by certain representational frameworks (e.g., adaptive reference points, boundaries) than others (e.g., exemplars, clusters).

Extrapolation Under Caricatured Representations

Modus tollens is a rule of inference in classical, two-valued logic which allows to derive the negation of the antecedent from a conditional and the negation of its consequent. In this paper, we investigate when humans draw such conclusions and what modulates the application of modus tollens. We consider conditionals which may or may not be obligations and which may or may not have necessary antecedents. We show that humans make significantly more modus tollens inferences in case of obligation conditionals and that the time to make a modus tollens inference is shorter than the time to answer ``nothing follows''. We illustrate how these differences can be modeled within the weak completion semantics.

When are Humans Reasoning with Modus Tollens?

The increased prevalence of “fake news" in recent years makes it important for us to better understand how we decide which information to trust and accept as true. Existing research has identified the important roles of factors such as trust in the source of the information and reading ability. We report on the results of a study on how the style of writing, and specifically the difficulty level of the text providing the information, affects our trust in the information provided. Participants trusted the information more in texts that were more difficult to read, regardless of whether the information presented was correct or incorrect. Regardless of readability, participants trusted paragraphs providing truthful information more than those providing false information. This result has important implications for information on social media platforms, where the source may or may not be readily available and is often not an expert on the topic.

The impact of readability on trust in information

Text skimming is a common reading behavior that occurs when readers scan text at a faster than normal rate to attempt to form understanding when not able to read at normal speed. Research has suggested that reading time varies across a skimmed text, guided by attention and comprehension goals. However, do individual differences in the ability to manage attention affect skimming? Are those better at managing attention (i.e., high working memory) also better at managing text skimming? Two experiments were conducted where participants who varied in WMC were asked to skim an unfamiliar expository text, both on a computer, and while being eyetracked. In both experiments, while participants did spend more time reading earlier portions of the text, this did interact with WMC. Those higher in WMC balanced their reading efforts more equally across the entire text, suggesting that text skimming behavior is sensitive to differences in WMC.

When laypeople decide if a costly intervention is an overreaction or an appropriate response, they likely base those judgments on mental simulation about what could happen, or what would have happened without an intervention. To narrow down from the infinite set of possibilities they could consider, they may engage in a process of sampling. We examine whether judgments of overreaction can be explained by a utility- weighted sampling account from the JDM literature, or a norm- weighted sampling account from the causal judgment literature, both, or neither. Three experiments test whether these judgments are overly influenced by low-risk bad outcomes (utility-weighted sampling), or by what is likely and prescriptively good (norm-weighted sampling). Overall, participants’ judgments indicate that they disregard low-risk bad outcomes, and even when a high-risk outcome is successfully avoided, the intervention is an overreaction. These results favor a norm-weighted sampling account in the specific case of evaluating overreactions.
