Network science provides a set of quantitative methods to investigate complex systems, including human cognition. Although cognitive theories in different domains are strongly based on network perspective, the application methodologies quantitatively study cognition has so far been limited scope. This review demonstrates how approaches have applied and can uniquely address provide novel insight important questions related complexity systems processes that occur within those systems. Drawing literature science, with focus semantic lexical networks, we argue three key points. (i) powerful approach represent (ii) The enables scientists achieve deeper understanding by capturing structure, i.e., underlying network, operating structure interact produce behavioral phenomena. (iii) framework model dynamics operationalized as structural changes timescales resolutions.

The relation between semantic memory structure, associative abilities, and verbal and figural creativity

Thinking & Reasoning, Journal Year: 2020, Volume and Issue: 27(2), P. 268 - 293

Published: Sept. 11, 2020

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. Associative mediated creativity, implying efficient spread information may via abilities. These findings support extend theory novel structure,

Quantifying flexibility in thought: The resiliency of semantic networks differs across the lifespan

Cognition, Journal Year: 2021, Volume and Issue: 211, P. 104631 - 104631

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.

Using Network Science to Understand the Aging Lexicon: Linking Individuals' Experience, Semantic Networks, and Cognitive Performance

Topics in Cognitive Science, Journal Year: 2022, Volume and Issue: 14(1), P. 93 - 110

Published: Jan. 1, 2022

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. To help fill this gap, we outline an empirical agenda utilizes network analysis involves concurrent assessment large‐scale networks performance younger older adults. present preliminary data establish feasibility limitations such empirical, network‐analytical approaches.

Age differences in semantic network structure: Acquiring knowledge shapes semantic memory.

Psychology and Aging, Journal Year: 2023, Volume and Issue: 38(2), P. 87 - 102

Published: Jan. 23, 2023

Computational research suggests that semantic memory, operationalized as memory networks, undergoes age-related changes. Previous work concepts in older adults' networks are more separated, segregated, and less connected to each other. However, cognitive network often relies on group averages (e.g., young vs. adults), it remains unclear if individual differences influence disparities language production abilities. Here, we analyze the properties of younger participants' individual-based based their relatedness judgments. We related measures-clustering coefficient (CC; connectivity), global efficiency, modularity (structure)-to (verbal fluency) vocabulary knowledge. Similar previous findings, found significant age effects: CC efficiency were lower, was higher, for adults. Furthermore, knowledge significantly measures: corresponding with effects, had a negative relationship, while positive relationship More generally, increased age, which may reflect critical role accumulation within has its structure. These results highlight impact diverse life experiences demonstrate importance accounting aging mental lexicon. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Cognitive modelling of concepts in the mental lexicon with multilayer networks: Insights, advancements, and future challenges

Psychonomic Bulletin & Review, Journal Year: 2024, Volume and Issue: 31(5), P. 1981 - 2004

Abstract The mental lexicon is a complex cognitive system representing information about the words/concepts that one knows. Over decades psychological experiments have shown conceptual associations across multiple, interactive levels can greatly influence word acquisition, storage, and processing. How semantic, phonological, syntactic, other types of be mapped within coherent mathematical framework to study how works? Here we review multilayer networks as promising quantitative interpretative for investigating lexicon. Cognitive map multiple at once, thus capturing different layers might co-exist This starts with gentle introduction structure formalism networks. We then discuss mechanisms phenomena could not observed in single-layer were only unveiled by combining lexicon: (i) multiplex viability highlights language kernels facilitative effects knowledge processing healthy clinical populations; (ii) community detection enables contextual meaning reconstruction depending on psycholinguistic features; (iii) layer analysis mediate latent interactions mediation, suppression, facilitation lexical access. By outlining novel perspectives where shed light representations, including next-generation brain/mind models, key limitations directions cutting-edge future research.

Successful problem-solving and enhanced creative ability may improve physical health, cognitive well-being, overall independence of older adults. In general, adults who are more creative, be better able to cope with decline navigate everyday tasks. While previous research on performance in adulthood showed age-related stability, open questions remain regarding the specific underlying basis for this invariability across lifespan.
