description Objective: This study aims to understand the impact of complexity factors on human decision-making performance in an economic problem (the Knapsack Problem), which is analogous to numerous situations individuals encounter daily related to the practices of administrators and managers. Methodology: The research employed an experimental design with 41 participants, varying the number of items and two metrics of computational complexity: "input size" and "instance correlation". Performance was assessed by measuring optimization performance, relative performance, response time (RT), and confidence. Results: The findings reveal a significant impact from manipulating the number of items, leading to a decrease in optimization performance and confidence, alongside an increase in RT. A phase transition was observed in relative performance, where participants managed increases from 5 to 6 items despite longer task completion times; however, this compensation was no longer feasible at 7 items. The input size measure was significantly associated with all dependent variables, explaining 51.84% of the variation in RT. Practical Implications: These results can be applied in areas involving complex decision-making, such as resource allocation and logistical planning. The research contributes to understanding human cognitive limitations, enabling the development of strategies that reduce errors and cognitive overload.

Metodologia: A pesquisa empregou um delineamento experimental com 41 participantes, variando o número de itens e duas métricas de complexidade computacional, "input size" e "instance correlation". Foi avaliada a performance por meio da mensuração do desempenho de otimização, desempenho relativo, RT e confiança. Resultados: Os resultados evidenciam um impacto robusto da manipulação do número de itens, resultando na redução do desempenho de otimização e confiança e aumento do RT. Encontrou-se uma transição de fase para o desempenho relativo, na qual os sujeitos suportaram aumentos de 5 para 6 itens em detrimento de realizar a tarefa em maior tempo, no entanto, para 7 itens tal compensação não foi mais possível. A medida input size associou-se significativamente com todas as variáveis dependentes, sendo capaz de explicar 51,84% da variação RT. Implicações práticas: Esses resultados podem ser aplicados em áreas que envolvem decisões complexas, como alocação de recursos e planejamento logístico, tendo em vista que a pesquisa contribui para o entendimento de limitações cognitivas humanas, possibilitando o desenvolvimento de abordagens que reduzam erros e sobrecarga cognitiva.Universidade Federal de Santa Maria2025-06-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/xmlhttps://periodicos.ufsm.br/reaufsm/article/view/8966710.5902/1983465989667Revista de Administração da UFSM; Vol. 18 No. 2 (2025): Apr-Jun; e1Revista de Administração da UFSM; Vol. 18 Núm. 2 (2025): Apr-Jun; e1Revista de Administração da UFSM; v. 18 n. 2 (2025): Apr-Jun; e11983-46591983-4659reponame:Revista de Administração da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMenghttps://periodicos.ufsm.br/reaufsm/article/view/89667/67381https://periodicos.ufsm.br/reaufsm/article/view/89667/67610Copyright (c) 2025 Carolina Schneider Bender, Mauri Leodir Löbler, Eliete dos Reis Lehnhartinfo:eu-repo/semantics/openAccessSchneider Bender, CarolinaLöbler, Mauri LeodirLehnhart, Eliete dos Reis2025-08-08T17:19:29Zoai:ojs.pkp.sfu.ca:article/89667Revistahttps://periodicos.ufsm.br/reaufsm/indexPUBhttps://periodicos.ufsm.br/reaufsm/oairea@ufsm.br || centraldeperiodicos@ufsm.br1983-46591983-4659opendoar:2025-08-08T17:19:29Revista de Administração da UFSM - Universidade Federal de Santa Maria (UFSM)false
