Social media is largely used as a tool to promote social connection among people and groups; yet that does not imply social media users are not lonely. Here we explore whether we can detect loneliness in individuals from their language and social indicators on Twitter. We define a sample of self-declared lonely Twitter users and compare their language to a matching random control sample. For each user we create a text em-
bedding for the content of their online posts, excluding terms and expressions related to loneliness. Using a principal component analysis of the resulting embeddings we position each user in a two-dimensional space spanned by the first two components. Lonely individuals are spatially separated from the control sample, indicating that lonely individuals exhibit distinct language patterns related to the expression of internalizing thoughts focused on the self, e.g. “I should” and “but I”. Indicators of online social relations, such as the number of online friends, favorites, mentions, indicate that lonely individuals have fewer social relations, while a sentiment analysis indicates that their posts have lower valence. Our results provide insights into the lexical, social, and affective markers that characterize loneliness online, providing a starting point for the development of diagnostics and prevention.

The 45th Annual Meeting of the Cognitive Science Society presents the latest research across cognitive science and highlights the theme of Cognition in Context.

Languages describe spatial relations in different manners. It is however hypothesized that highly frequent ways of categorizing spatial relations across languages correspond to the natural ways humans conceptualize them. In this study, we explore the use of machine translation to gather data in semantic typology to address whether different languages show similarities in how they carve up space. We collected spatial descriptions in English, translated them using machine translation, and subsequently extracted spatial terms automatically. Our results suggest that most spatial descriptions are accurately translated. Despite limitations in our extraction of spatial terms, we obtain meaningful patterns of spatial relation categorization across languages. We discuss translation limits for semantic typology and possible future directions.

Classifiers are a noun categorization device found in many East and Southeast Asian languages. Their syntactic status is debated: some theories treat them as forming a constituent with the noun, others with the numeral. Typological data on how classifiers, numerals, and nouns are ordered largely support the classifier-with-numeral hypothesis: orders in which the noun intervenes between the numeral and the classifier are unattested. However, typological evidence is problematic in this case, because the distribution of classifiers is highly geographically constrained, and ordering tendencies may reflect language contact. In this study, we look for evidence of the syntactic status of classifiers using artificial language learning experiments. We test whether learners’ preference among patterns are predicted by one of these two accounts. Results suggest that, if anything, learners in fact prefer orders that group classifiers with the numeral.

Cognitive biases for word order between numeral, classifier and noun

Automated Writing Evaluation (AWE) tools are steadily gaining prominence in educational settings given the ease and scale in which they can be deployed. Nevertheless, despite producing a similar performance as human raters, the accuracy of automated systems is often met with skepticism. In the current study we explore whether such skepticism extends to writing feedback believed to be generated by human tutors in training or an AI tutor under development. When both sources are fallible, are critical judgments mitigated? Participants (N=477) judged the accuracy of feedback on writing samples given by human or AI tutors where the feedback was normed to be accurate, inaccurate, and ambiguous. Results showed participants were still more likely to deem identical feedback provided by an AI, as compared to human tutors, as less accurate, and they were more confident in these evaluations. It appears that “novice” AWE systems are not completely immune to negative bias.

Curiosity relates to learning and recent work shows robust associations between curiosity and recall of information in adults and children over age 10. The current study tested a similar association in younger children and explored children’s information-seeking behaviors. Children (n=90, 4-10-year-olds) played a free-exploration game in which they clicked shapes to learn different facts about different topics. They then recalled what they remembered learning on the task (recall) and asked questions about what they were curious to know more about (curiosity). We observed a positive association between children’s curiosity and recall of information, even when controlling for amount of information seeking and children’s age. This association was specifically seen for recall without memory cues. There was no association between children’s curiosity and information seeking behavior, and children showed a strong tendency of breadth exploration over exploring in depth with some indication of children beginning to explore depth more with age.

Categories simplify the vast number of entities we encounter into equivalence classes, serving as a fundamental block of our cognition. This simplification of information supports our ability to reason about and interact with members of each category. In adulthood, selective attention helps us form categories efficiently by focusing on relevant attributes while filtering out irrelevant information. However, young children tend to encode more attributes than necessary, and this developmental difference is partly due to a prolonged development of selective attention. In the current study, we proposed another important contributor to the development. As shown in three experiments, children prefer information gathering to efficiency, regardless of its value. Experiment 1 revealed that children sample more information than adults even when filtering demands are low. Experiment 2 further supports children's preference for information. And Experiment 3 eliminates alternative explanations, demonstrating that children enjoy gathering information rather than motor actions associated with it.

Driven by Information: Children's Exploration Shapes Their Distributed Attention in Category Learning

Young children acquire a wide range of linguistic and cognitive skills in the first three years of life. Decades of experimental work have established a solid empirical foundation for our understanding of cognitive development. But most experimental studies are limited in statistical power and focus on specific psychological constructs, thus making them unsuitable for describing developmental growth at scale. Here, we turned to meta-analyses of experimental research. We conducted a meta-meta-analysis to consolidate and integrate 23 meta-analyses compiled on MetaLab, a community-augmented meta-analysis platform. We found that most datasets can not meaningfully distinguish different functional forms for developmental change, but in those that could, there is great diversity in the best-fitting functional forms of the age model. We also evaluated the impact of a range of methodological factors. Overall, our work sheds light on the heterogeneous nature of developmental trajectories and the subtle interactions between research methods and experimental outcomes.

Quantitative models of behavior are a fundamental tool in cognitive science. Typically, models are hand-crafted to implement specific cognitive mechanisms. Such "classic" models are interpretable by design, but may provide poor fit to experimental data. Artificial neural networks (ANNs), on the contrary, can fit arbitrary datasets at the cost of opaque mechanisms. Here, we adopt a hybrid approach, combining the predictive power of ANNs with the interpretability of classic models.
We apply this approach to Reinforcement Learning (RL), beginning with classic RL models and replacing their components one-by-one with ANNs. We find that hybrid models can provide similar fit to fully-general ANNs, while retaining the interpretability of classic cognitive models: 
They reveal reward-based learning mechanisms in humans that are strikingly similar to classic RL. They also reveal mechanisms not contained in classic models, including separate reward-blind mechanisms, and the specific memory contents relevant to reward-based and reward-blind mechanisms.

Predictive and Interpretable: Combining Artificial Neural Networks and Classic Cognitive Models to Understand Human Learning and Decision Making

Dependency tree is efficient for relation extraction model to exploit relations between words. Recent approaches have achieved promising performance while still suffering from inherent limitations. 
In this paper, we propose a novel relation extraction framework called Progressive Graph Learning over pruned dependency tree (PGLNet). PGLNet constructs a set of graphs by progressively adapting to input sentence. Specially, we implement the model to construct progressive weighted adjacency matrices by learning the relations among graph nodes with self-attention mechanism. Then, the model takes the learned weights as reference to prune dependency tree. Next, progressive convolution module is designed to encode the relations of entities and followed by relations classification. We evaluate our proposed model using public real-world datasets, experimental results demonstrate that the proposed model achieves state-of-the-art performance with consistency in all datasets. We conclude that the ability of PGLNet to progressively adapt to input data and enable the model with robustness.


Progressive Graph Learning over Pruned Dependency Trees For Relation Extraction

In this work, we develop convolutional neural generative coding (Conv-NGC), a generalization of predictive coding to the case of convolution/deconvolution-based computation. Specifically, we concretely implement a flexible neurobiologically-motivated algorithm that progressively refines latent state feature maps in order to dynamically form a more accurate internal representation/reconstruction model of natural images. The performance of the resulting sensory processing system is evaluated on complex datasets such as Color-MNIST, CIFAR-10, and Street House View Numbers (SVHN). We study the effectiveness of our brain-inspired model on the tasks of reconstruction and image denoising and find that it is competitive with convolutional auto-encoding systems trained by backpropagation of errors and outperforms them with respect to out-of-distribution reconstruction (including the full 90k CINIC-10 test set).


Convolutional Neural Generative Coding: Scaling Predictive Coding to Natural Images

The concept of a good life is usually assumed by philosophers to be equivalent to that of well-being, or perhaps of a morally good life, and hence has received little attention as a potentially distinct subject matter. In a series of experiments participants were presented with vignettes involving socially sanctioned wrongdoing toward outgroup members. Findings indicated that, for a large majority, judgments of bad character strongly reduce ascriptions of the good life, while having no impact at all on ascriptions of happiness or well-being. Taken together with earlier findings these results suggest that the lay concept of a good life is clearly distinct from those of happiness, well-being, or morality, likely encompassing both morality and well-being, and perhaps other values as well: whatever matters in a person’s life. Importantly, morality appears not to play a fundamental role in either happiness or well-being among the folk.
