The proliferation of the capability for producing and distributing deepfake videos threatens the integrity of systems of justice, democratic processes, and the general ability to critically assess evidence. This study sought to identify individual differences that predict one’s ability to detect these forgeries. It was hypothesized that measures of affect detection and political orientation would correlate with performance on a deepfake detection task. Within a sample (N = 173) of college undergraduates and participants from Amazon’s M-turk, affect detection ability was shown to correlate with deepfake detection ability, r(171) = .73, p &lt; .001, and general orientation to the political left was shown to correlate with deepfake detection ability, r(171) = .42, p &lt; .001. The results of this study serve to identify populations who are particularly susceptible to deception via deepfake video and to inform the development of interventions that may help defend against attempts to influence them.

The Cognitive Science Society brings together researchers from around the world who hold a common goal: understanding the nature of the human mind. The mission of the Society is to promote Cognitive Science as a discipline, and to foster scientific interchange among researchers in various areas of study, including Artificial Intelligence, Linguistics, Anthropology, Psychology, Neuroscience, Philosophy, and Education. The Society is a non-profit professional organization and its activities include sponsoring an annual conference and publishing the journals Cognitive Science and TopiCS.

A pilot study (n=68) investigated participants’ emotional valence after reading sentences that varied in self-relevance (referring to the participant/someone else), valence (positive/negative), and the gender of the person expressing the sentence (man/woman). Positive sentences induced more positive emotion than negative sentences. Self-relevance enhanced the emotional response, with positive self-relevant sentences rated more positively than positive other-relevant sentences, and negative self-relevant sentences rated more negatively than negative other-relevant sentences. Gender impacted these responses. First, the difference in emotional valence felt in response to positive versus negative sentences was larger for women than men – women responded more positively to positive sentences than men. Second, self-relevance enhanced the positive emotion in response to positive sentences more strongly when the sentence came from the opposite gender. These findings suggest that women may have stronger responses to emotional sentences and that processing biases may exist to prioritize positive self-relevant information from the opposite gender.

Delays between causes and effects are commonly found in cause-effect relationships in real life. However, previous studies have only investigated delays on the order of seconds. In the current study we tested whether people can learn a cause-effect relation with hour long delays. The delays between the cause and effect were either 0, 3, 9, or 21 hours, and the study lasted 16 days. Surprisingly, we found that participants were able to learn the causal relation about equally as well in all four conditions. These findings demonstrate a remarkable ability to accurately learn causal relations in a realistic timeframe that has never been tested before.

Causal Learning With Delays Up to 21 Hours

Representing a location in space requires two things: an anchor point, and a code (or coordinate system) to define other locations relative to that anchor point. Recent work has shed light on the latter, providing evidence that the default ‘format’ of visuospatial representation may be polar coordinates (i.e., angle/distance relations). Yet the former remains a topic of debate. For example, a classic distinction in the realm of spatial navigation research pits representation relative to landmarks against representation relative to boundaries. Here, we exploit the polar format of spatial representations to propose a new method for assessing the locus of spatial representation. Specifically, we show that from simple localization errors we can infer the anchor point from which observers localized a target point. We highlight a few basic demonstrations of this method and discuss possible applications for further research on spatial representation.

‘Decoding’ the locus of spatial representation from simple localization errors

We explore the dynamic coordination of perception, decision, and action underpinning perceptual choices by recording cursor movements during a binary response task. Stimuli were presented sequentially to control the time-course of perception, and we utilized a Hidden Markov Model (HMM) to relate measured movements of the mouse cursor to latent cognitive processes. Stimuli were simple perceptual objects comprised of two features, one of which was fully diagnostic of the correct response, while the other provided a probabilistic cue. The order of their arrival varied across trials, allowing us to manipulate the order of feature processing. The model builds upon response time methods and makes predictions about when individual features were perceived and the accumulation of evidence towards a response, every 10 milliseconds of each trial.

Dynamic Perception Revealed by Cursor Movements and Hidden Markov Modeling

A good deal of recent research has examined children’s norm learning across a wide range of novel contexts. The typical interpretation of these findings is that children’s norm learning is driven by group-based biases. In this paper, we present an alternative interpretation and corresponding meta-analyses that cast the current body of evidence in a rather different light. First, we argue the extant literature uses an ill-suited standard for assessing bias. Rather than comparing children’s judgments to what is expected under random chance (a ‘random standard’), bias is better assessed by comparing children’s judgments to what is most probable, given their total evidence (an ‘evidential standard’). Next, we report a meta-analysis of the known findings to date (k = 40 effect sizes; N = 1,369 in total; ages 4- to 13-years-old) to compare children’s norm learning against an appropriate evidential standard. Meta-analytic estimates reveal that children’s norm learning is not restrictively biased toward narrow-scope inferences on account of group-based factors. Rather, the findings to date are consistent with children’s norm learning being rational (i.e., statistically appropriate, given their evidence) or even inclusively biased toward making the wide-scope inference that a novel norm applies to everyone in a population. We conclude with brief discussion of implications for current understanding and future research on norm acquisition.

Is children's norm learning rational? A meta-analysis

Is language unique in how it evokes conceptual content, and if so, why? In an influential study, Lupyan & Thompson-Schill (2012) report that labels (nouns like “dog”) have a stronger cuing effect in picture verification tasks than “equally informative
and predictive nonverbal cues”, like the sound of a barking dog. Here we sought to better understand the factors that lead to a label advantage. First, while we replicate the label advantage itself, our data do not support the assumption that labels and environmental
sounds are equally informative. Instead, we show that different cue types are associated with target images to different degrees, and that labels show the strongest association. Moreover, the degree of association is a better predictor of reaction times than cue type. Thus, we conclude that labels are not more effective at activating the same semantic content than non-verbal cues, but rather activate different semantic content.

Deconstructing the Label Advantage Effect

If speakers communicate efficiently, they should produce more linguistic material when comprehension difficulty increases. Comprehension difficulty can be impacted by the message itself (studied extensively) or by properties of the listener (studied less). Here we investigate the impact of listeners’ estimated proficiency on speakers’ productions, using referential choice as a case study. Compared to full noun phrases (fNPs, ‘the woman’), pronouns (‘she’) can convey similar content with less linguistic material: accordingly, speakers use more fNPs when the message is unpredictable (Tily & Piantadosi, 2009) and when listeners lack relevant information (Bard & Aylett, 2004). If referential choice is also impacted by listeners’ estimated proficiency, then speakers should use more fNPs when conversing with language learners. To test this, we compared participants' descriptions of the same picture book to learners and proficient speakers. Indeed, participants used more fNPs when their interlocutors were child- or adult-learners, illustrating efficient adaptation to listener type.

Studies have shown that video game players exhibit superior performance to non-video game players on a number of cognitive tasks. Methods to compare the groups have
mainly involved using measures of central tendency such as the mean without examining intra-individual differences in performance. In the present study, top-ranking Tetris players and novice Tetris players completed a reaction time cognitive task. Results show that the top-ranking players exhibit faster reaction times compared to novice players. Beyond the mean RT, we used the ex-Gaussian modeling technique and found differences in variability and attention between the two groups. Future studies can use modeling techniques such as the exGaussian distribution to analyze the whole distribution at an
individual level beyond measures of central tendency and further examine the behavioral differences between video game players and non-video game players.

To hold someone responsible, we need to assess what causal role their action played in bringing about the outcome. Causality, in turn, can be understood in terms of difference-making -- C caused E if E would have been different had C been different. In previous work, the counterfactual of “C being different” is often construed as “C being absent”. Here, we explore how in social situations, this counterfactual can be alternatively construed by imagining how a different person would have acted in the same situation. We propose a computational model that formalizes this idea of counterfactual replacement. The model compares what actually happened with what would have happened had the person of interest been replaced by someone else, and then predicts responsibility to the extent that the replacement person would likely have changed the outcome. We test our model against people’s responsibility judgments in a variety of scenarios across several experiments.

The role of counterfactual reasoning in responsibility judgments

Although the Traveling Salesman Problem (TSP) is an NP-hard problem, human schedulers can find strategies that are comparable if not better than existing algorithms. However, it is still unclear what heuristics they adopt in order to select an approximate solution (Schaefer, 2018). In solving a navigational problem in 3D, the directional heading is an essential factor because changes of direction require additional energy expenditure. In our study, we focus on the connection between local choices minimizing distance and local choices minimizing the turning angle. We then examine human solutions to the TSP in light of the tradeoff between local and global optimization of distance and turning angle. We conducted two experiments showing that while subjects were more likely to move to the nearest node when they plan the next step ahead, they also take the turning angle into consideration and overall adopt a strategy that combines local and global heuristics.
