Social media are digitalizing massive amounts of users' cognitions in terms timelines and emotional content. Such Big Data opens unprecedented opportunities for investigating cognitive phenomena like perception, personality, information diffusion but requires suitable interpretable frameworks. Since social data come from minds, worthy candidates this challenge networks, models cognition giving structure to mental conceptual associations. This work outlines how network science can open new, quantitative ways understanding through online like: (i) reconstructing users semantically emotionally frame events with contextual knowledge unavailable machine learning, (ii) salience/prominence discourse; (iii) studying personality traits openness-to-experience, curiosity, creativity language posts; (iv) bridging cognitive/emotional content dynamics via multilayer networks comparing the mindsets influencers followers. These advancements combine cognitive-, network- computer understand mechanisms both digital real-world settings limitations concerning representativeness, individual variability, integration. aspects discussed along ethical implications manipulating sociocognitive data.

Abstract Creative ideas likely result from searching and combining semantic memory knowledge, yet the mechanisms acting on to yield creative remain unclear. Here, we identified neurocognitive correlates of search components related abilities. We designed an associative fluency task based polysemous words distinguished two clustering switching between different meanings words. Clustering correlated with divergent thinking, while ability combine remote associates. Furthermore, structure executive abilities, was predicted by connectivity default, control, salience neural networks. In contrast, relied interactions salience, attentional Our results suggest that captures control processes guiding whereas may capture controlled for persistent search, alternations exploratory focused attention support creativity.

The field of cognitive aging has seen considerable advances in describing the linguistic and semantic changes that happen during adult life span to uncover structure mental lexicon (i.e., repository lexical conceptual representations). Nevertheless, there is still debate concerning sources these changes, including role environmental exposure several mechanisms associated with learning, representation, retrieval information.

Abstract Successful navigation of the Covid-19 pandemic is predicated on public cooperation with safety measures and appropriate perception risk, in which emotion attention play important roles. Signatures are present social media data, thus natural language analysis this text enables near-to-real-time monitoring indicators risk perception. We compare key epidemiological progression constructed from $$\sim 20$$ ∼20 million unique Covid-19-related tweets 12 countries posted between 10th March 14th June 2020. find evidence psychophysical numbing: Twitter users increasingly fixate mortality, but a decreasingly emotional analytic tone. Semantic network based word co-occurrences reveals changes framing casualties that consistent hypothesis. also average afforded to national mortality rates modelled accurately Weber–Fechner power law functions sensory Our parameter estimates for these models psychological experiments, indicate dataset exhibit differential sensitivity by country death rates. work illustrates potential utility guiding communication during crisis scenarios.

Cognitive and neuroimaging evidence suggests that episodic semantic memory—memory for autobiographical events conceptual knowledge, respectively—support different aspects of creative thinking, with a growing number studies reporting activation brain regions within the default network during performance on thinking tasks. The present research sought to dissociate neural contributions these memory processes by inducing or retrieval orientations prior divergent task fMRI. We conducted representational similarity analysis (RSA) identify multivoxel patterns activity were similar across induction (episodic semantic) idea generation. At behavioral level, we found was associated increased originality, assessed via computational estimates distance between concepts.

Research has independently highlighted the roles of semantic memory and associative abilities in creative thinking. However, it remains unclear how these two capacities relate to each other, nor they facilitate different thinking modalities, such as verbal figural creativity. This study employed multiple cognitive tests network science methodologies shed light on relationship between them. We constructed individual-based networks assessed abilities, In line with previous studies, we found a relation creativity more flexible structure (higher connectivity, shorter distances concepts, lower modularity). did not find any structure.

Older adults tend to have a broader vocabulary compared younger – indicating richer storage of semantic knowledge but their retrieval abilities decline with age. Recent advances in quantitative methods based on network science investigated the effect aging memory structure. However, it is yet be determined how this structure relates its overall flexibility. Percolation analysis provides measure flexibility network, by examining resistant “attacks” or breaking apart. In study, we incorporated percolation analyses examine networks and older break apart investigate potential age-related differences language production. We applied 3 independent sets data (total N = 78 younger, adults) from which generated verbal fluency performance. Across all datasets, integrals were larger than adults, that adults' less flexible broke down faster adults'. Our findings provide evidence for diminished networks, despite stability across lifespan.

Associative theories of creativity argue that creative cognition involves the abilities to generate remote associations and make useful connections between unrelated concepts in one’s semantic memory. Yet, whether how real-life behavior relies on memory structure its neural substrates remains unclear. We acquired multi-echo functional magnetic resonance imaging data while participants underwent a relatedness judgment task. These ratings were used estimate their individual networks, whose properties significantly predicted creativity. Using connectome predictive modeling approach, we identified patterns task-based connectivity creativity-related network properties. Furthermore, these mediated relationship results provide new insights into brain support via also show computational science can be couple behavioral, cognitive, levels analysis.

Abstract People undergo many idiosyncratic experiences throughout their lives that may contribute to individual differences in the size and structure of knowledge representations. Ultimately, these can have important implications for individuals' cognitive performance. We review evidence suggests a relationship between experiences, semantic representations, as well age conclude extent which experience‐dependent changes representations aging remains unclear.
