Dendrophilia — a widespread proclivity toward hierarchical behavior — has long been argued to be central to human cognitive uniqueness. Alternative views emphasize the developmental and evolutionary continuity of complex hierarchical psychological processes with simpler sequencing mechanisms. We investigated the predispositions of human adults and 3-to-6-year-old children to spontaneously generate hierarchical patterns in an open-ended sequence generation task. We also compared the human ability to learn hierarchical patterns with that of rhesus macaques and carrion crows. Our Bayesian mixture model quantified the extent to which distinct mechanisms — associative chaining, linear iteration, queues, and stacks — were implicated in hierarchical behavior. Our results suggest that hierarchical behavior is possible across species. It emerges early in cognitive development and may be scaffolded by simpler cognitive processes that eventually increase in representational and computational complexity. Thus, our findings contradict the dendrophilia hypothesis and point to shared psychological processes underpinning hierarchical behavior.

#### About

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.

#### Our History 

* **Society Creation**<br>
The Society was incorporated as a 501(c)(3) non-profit professional organization in Massachusetts in 1979. The organizing committee included Roger Schank, Allan Collins, Donald Norman, and a number of other scholars from psychology, linguistics, computer science, and philosophy. 
<br><br>
* **Conference Creation**<br>
The first conference on cognitive science was held at La Jolla, California in August, 1979, and has occurred annually since then. The proceedings of each conference are published, and those from most years are available through Lawrence Erlbaum Associates, Inc. The annual proceedings of the Cognitive Science Conference represent a major source of information on new work and new ideas in the scientific study of thinking. In 1990, the Society, with help from an anonymous donor, established the David Marr Prize for the best student paper at each annual meeting.
<br><br>
* **Journal Creation**<br>
The Journal, Cognitive Science, began publication in 1976, and is now published by Wiley-Blackwell. The Executive Editor is currently Richard P. Cooper of Birkbeck, University of London, and there are 18 Associate Editors and a 30-member editorial board. It serves as the premier outlet for research reports that intersect two or more disciplines. Copyrights for articles published in the journal are held by the Society. The Governing Board of the Cognitive Science Society voted in late 2006 to found a new journal, Topics in Cognitive Science (topiCS). The Editor in Chief is Wayne Gray, Cognitive Science Department, Rensselaer Polytechnic Institute. The journal seeks to fill a niche not occupied by Cognitive Science Journal or other cognitive science journals. Membership in the Society includes a subscription to Cognitive Science and TopiCS. Copyrights for articles published in the journal are held by the Society.

The 46th Annual Meeting of the Cognitive Science Society presents the latest research across cognitive science and highlights the theme of Cognition in Context.

Sustained attention is a fundamental cognitive ability that influences various aspects of human functioning. Studies of the neural correlates of attention commonly treat sustained attention as an isolated construct, however in any ecological context, sustained attention interacts with other executive functions such as inhibition of interference and processing of complex hierarchical stimuli. We have thus constructed a protocol to probe the interplay between these cognitive processes during visual attention task. We contrast putative typical vs atypical attention by comparing 18 healthy participants with 53 adults with Attention-Deficit/Hyperactivity Disorder, for whom difficulties with sustained attention are a core symptom and thus constitute a natural experiment condition. Our behavioural and brain-imaging analyses demonstrate distinct neural patterns in bottom-up visual processing and attention allocation mechanisms in ADHD and Control groups, highlighting different cognitive strategies utilised by adults with ADHD and healthy participants in tasks requiring sustained attention.

Neurotypical Adults employ Distinct Cognitive Strategies compared to Adults with ADHD during a Sustained Attention Task with Gestalt Stimuli

Causal reasoning enables us to explain the past, predict the future, and intervene in the present. Does the brain allocate specialized cortical regions to causal reasoning? And if so, are they involved in reasoning about both physical and social causal relationships, or are they domain-specific? In a pre-registered experiment (Exp 1) we scanned adults using fMRI while they matched physical and social causes to effects (e.g., ‘The car swerved to avoid a crash’ -> ‘Coffee spilled all over the car seat’; ‘He was late for work’ -> ‘Tom was scolded by his boss’) or physical and social descriptions of the same entity matched for difficulty and linguistic variables to the causal conditions (e.g., ‘The brightest object in the sky’-> ‘The closest star to earth’; ‘She works at a hotel’ -> ‘She brings in guests’ luggage’). A region in the left lateral prefrontal cortex (LPFC) responded significantly more strongly to causal than descriptive conditions in most subjects individually. Responses in this region in held-out data were high for both social and physical causal conditions, yet no greater than baseline for the two descriptive (non-causal) conditions. In a follow-up exploratory experiment (Exp 2), we tested a different task (answering causal versus non-causal questions about physical and social narratives, matched for linguistic variables). Again, we found that both the physical and social causal stimuli selectively engaged the LPFC region. Finally, in both experiments, we found that brain regions previously implicated in intuitive physical reasoning responded more to the physical causal than the physical non-causal stimuli. Collectively, these results suggest that a) a region in the LPFC is selectively engaged in causal reasoning independent of content domain and b) the hypothesized physics network (hPN) is selectively involved in physical causal reasoning across modalities (visual vs. linguistic).

A region in human left prefrontal cortex selectively engaged in causal reasoning

Cognitive scientists continue to debate gender/sex differences in basic problem-solving, including numerical and spatial cognition. While such differences may exist in adulthood, it is unclear whether these cognitive skills are fixed (early-developing, permanent) or plastic (late-developing, malleable). If fixed, they would relate more to gender categories; if plastic, they would relate more to gender socialization and spatial learning environment. To disentangle these hypotheses, we measured brain activity with fMRI in 51 children (4-8y; 20 boys / 31 girls) during numerical (vs. face) and geometric (vs. word) processing tasks. Greater activity occurred in superior and inferior parietal cortex during numerical and geometric processing compared to control conditions, but activity was unrelated to gender category, gender socialization, or spatial learning environment. These initial findings challenge the hypothesis of early, fixed gender effects in numerical and spatial development. Bayesian analyses will quantify support for the null vs. experimental hypotheses, incorporating additional environmental predictors.

Plasticity, gender, and the environment during numerical and spatial development

Transcranial alternating current stimulation (tACS) is an efficient neuromodulation technique to enhance cognitive function in a non-invasive manner. Using electroencephalography and functional magnetic resonance imaging, it was investigated whether a tACS with different phase lags between central executive and default mode networks modulated cognitive performance in perception, working memory, and inhibitory control. It was found that phase-lag-dependent tACS mediated improvement in task performance, neurodynamically reflected in task-relevant cortical and subcortical activation as well as prefrontal-based top-down functional connectivity. Our observations provide neurophysiological correlates of network-wise tACS-phase-dependent neuromodulation and a feasible non-invasive approach to effectively modulate fundamental cognitive functions.

Measuring and quantifying degrees of belief poses a fundamental challenge, prompting an exploration into how humans navigate uncertainty. This study challenges the conventional use of probability theory and investigates ranking theory as a viable alternative model. Across the initial three experiments (N = 168; N = 63; N = 200), participants consistently utilized negative ranking functions to express disbelief, revealing a robust pattern across diverse contexts. Notably, a logarithmic relationship emerged between subjective probability and negative ranks (degree of disbelief). Experiment 3 provided clarity regarding the association between subjective probability and two-sided ranks (degree of disbelief and belief), establishing a log-odds relationship. In Experiment 4 (N = 268) the examination of ranks and subjective probability in a learning task revealed that degrees of disbelief more accurately represented the objective probability distribution than subjective probability. Lastly, Experiment 5 (N = 291) addressed decision-making under uncertainty through the Ellsberg paradox, uncovering how ranking theory not only resolved contradictions with expected utility theory but also eliminated the paradoxical nature of the Ellsberg scenario. This study advances our understanding of human uncertainty and supports ranking theory as a compelling alternative.

To what degree does semantic foraging probe semantic network structure? We use a combination of foraging experiments (animals, concrete nouns) and simulations on networks based on nine approaches to semantic similarity to address this question. In data and simulations, we find a significant bias towards naming semantically similar items, and significant correlations between inter-naming time and semantic distance. In previous foraging experiments, a roughly power law distribution with a Lévy range exponent was found in the distribution of inter-naming intervals. We find the value of this exponent is not universal but is sensitive to the search space size in that the exponent decreases (moving further into the Lévy range) as the number of nameable items is exhausted. Moreover, these exponents are not unique to semantic networks but appear in censored random walks on other graphs. Our combined experimental results and simulations provide insights into the topology of semantic memory.

Nonuniversal foraging behavior in semantic networks

Pupil dilation is assumed to be a slow and indirect reflection of latent cognitive events. Deconvolution approaches promise a more precise study of these events, assuming that they all trigger a delayed pupil response.

However, conventional deconvolution approaches neglect the possibility that between-event timings and the shape of the pupil responses differ between subjects, trials, and cognitive events. Accounting for this variability however is crucial to 1) achieve precise recovery of latent events and 2) to investigate how trial-level predictors influence cognitive processes.

We present a new method that performs trial-level deconvolution by combining generalized additive mixed models with Hidden semi-Markov models. We tested this method on synthetic data and subsequently applied it to data from a lexical decision experiment (N=24) and recovered six processing events. Investigating the trial-level durations of the recovered events revealed that early visual and late decision-related processing were influenced differently by frequency and word-type.

Recovering cognitive events from trial-level pupil time courses

The desire to move to music appears to be a human universal. This behavioral response seems to be supported by a tight coupling of auditory and motor networks, even in the absence of overt movement. The prevailing theories explain this phenomenon either in terms of passive brain network entrainment to musical periodicity or motor system involvement in predictive coding. Both explanations recognize the role of rhythmic complexity in modulating motor activity. However, the precise nature of the relationship between rhythmic complexity and motor activity remains unclear. In this work, we conducted an fMRI literature review to examine this relationship. Out of 110 screened articles, 24 met inclusion criteria, reporting findings ranging from non-existent to linear or Inverted-U-shaped relations. Underlying these findings, we encountered significant heterogeneity in the measurement and conceptualization of rhythmic complexity. We provide a summary of the associations found, the approaches to measuring rhythmic complexity and the different types of tasks and stimuli used. We conclude that, in order to move forward, more agreement is needed regarding measures and notions of complexity.

The role of the motor system in the processing of rhythmic complexity: a critical review

Self-regulated learning may be crucial for goal setting, progress monitoring, and adaptive problem-solving. The ability to find and recognize relevant and reliable information has become increasingly valuable. Therefore, to understand self-regulated learning processes, we interviewed 138 9-11-year-olds to analyze their information-seeking behaviors when learning either novel or partially known concept by themselves.
Children’s responses were categorized into two groups: relying on People and opting for Platforms. Results revealed an overall preference for platforms (73.23%). Interestingly, when learning novel concepts, the proportion favoring human sources increased significantly (34.56% versus 18.80%).
Most of the children mentioned changing their strategy when stuck during the learning process (79.93%), with platform learners showing higher adaptability (89.34%) than those relying on humans (54.17%).
These findings deepen our understanding of children’s decision-making regarding learning, aiding teachers in guiding their learning processes more efficiently, valuable not only in educational settings, but also in their personal and professional lives.

Differences in Learning Novel and Partially Known Concepts: Exploring Children’s Self-Regulated Choices

Procrastination is a universal phenomenon, with a significant proportion of the population reporting interference and even harm from such delays. Why do people put off tasks despite what are apparently their best intentions, and why do they deliberately defer in the face of prospective failure? Past research shows that procrastination is a heterogeneous construct with possibly diverse causes. To grapple with the complexity of the topic, we construct a taxonomy of different types of procrastination and potential sources for each type. We simulate completion patterns from three broad model types: temporal discounting, inconsistent discounting, and waiting for interesting tasks, and provide some preliminary evidence, through comparisons with real-world data, of the plausibility of multiple types of, and pathways for, procrastination.
