“…As predicted by MRT, we did observe a dual-task decrement within this study. When compared to the dynamic search task performed by Jackson et al (2022), participants in this study experienced less of a decrement for both tasks. In this experiment, participants found 14.2% less search targets and recalled 27.9% less words when multitasking compared to performing each task individually.…”

“…We expected to observe a dual-task decrement when participants multitasked as opposed to when they performed the tasks individually. We also expected to find less of a dual-task decrement within this study than in the dynamic search task performed by Jackson et al (2022). Finally, we expected participants to inherently prioritize one task over the other, despite being instructed not to, in the dualtask, where responses to a subjective measure could show task performance differences.…”

“…Previous research has sought to understand multitask performance using HUDs in a variety of contexts. For example, Green & Helton (2011) examined climbing and word recall using a HUD, Lewis & Neider (2016) examined visual search and a recognition memory task using a HUD, and recently, Jackson et al (2022) examined a dynamic visual search and word recall using a HUD within a virtual environment. Within all the studies, significant dual-task interference was found.…”

Visual searches are done frequently and commonly while doing other tasks. Previous research has shown that multitasking inhibits performance of tasks done together, however little has examined visual search and word recall performed together, especially when there are an undisclosed number of targets to be found. The purpose of this study is to examine how multitasking affects visual search and word recall. Participants recalled words shown on a heads-up display while simultaneously searching realistic landscape images for target distortions. The participants also completed these tasks individually. It was found that during multitasking, participants found significantly less targets and remembered significantly less words than when doing those tasks individually. It was also shown that prioritizing tasks led to small improvements in performance for that task. The results of this study could be used to influence design of technology made for individuals searching environments who also need to communicate information.

“…Tais resultados permitiram concluir que a tarefa cognitiva concorre com os desafios de controlo postural. Por outro lado, os autores Jackson et al (2022) avaliaram a performance motora durante uma dupla tarefa com desafio cognitivo de memória, bastante idêntico ao requerido durante o jogo Labirinto. Neste estudo, os autores solicitaram a nomeação de 20 palavras numa tarefa motora de 5 minutos, requerendo posteriormente a sua recapitulação.…”

Introdução: A utilização do jogo, enquanto sistema de avaliação em dupla tarefa, tem vindo a demonstrar um potencial relevante pelas suas propriedades. Objetivo: Testar a aplicabilidade do jogo analógico na avaliação de dupla tarefa em pessoas idosas. Metodologia: Foi realizado um estudo observacional, transversal, com uma mostra de 13 idosos com capacidade de caminhar curtas distâncias. A amostra foi caracterizada nas variáveis sociodemográficas, da mobilidade funcional (Timed-up and Go Test-TUG) e da função cognitiva (6-CIT). Os participantes foram avaliados na sua performance (tempo/seg.) no jogo Labirinto (Agilidades, Inc.) nas diferentes modalidades: grelhas de jogo limpo (S, M e L) vs grelhas de jogo com pistas cognitivas. Para cada modalidade foram recolhidas 3 tentativas. Depois de uma análise descritiva (mediana, IIQ) da performance no jogo, no TUG e no 6-CIT, foi analisada a diferença estatística entre níveis de jogo (wilcoxon) e calculada a correlação entre a performance, o TUG e o 6-CIT. Resultados: Na modalidade de jogo limpo a mediana do tempo aumenta de acordo com a dimensão das grelhas (S:7.67 - L: 14.50);correlações fortes foram encontradas entre o TUG e o tempo nas grelhas S (r=0.802) e L (r=0.808).A variabilidade entre tentativas é superior para a grelha Mpistas (1.53-20.67). Entre o 6-cit e o Spistas (0.580), Mlimpo (0.639) e Mpistas (0,636) foram detetadas correlações moderadas. Conclusão: Dificuldades de equilíbrio resultam num aumento de dificuldade no desempenho no jogo limpo. Algumas adaptações ao protocolo do Jogo podem ser determinantes para garantir condições de segurança na avaliação de dupla tarefa em idosos.

“…The participants at the end of each experimental condition responded with as many of the 20 words as they could recall. This task has been used extensively in dual-task studies (Darling & Helton, 2014; Epling, Blakely, et al, 2016; Epling, Russell, et al, 2016; Epling et al, 2017; Green et al, 2014; Green & Helton, 2011; Jackson et al, 2022; 2023; Stets et al, 2020; Woodham et al, 2016).…”

Wearable displays may enhance information access, but potential interference between device use and the primary operational task may result. Multiple Resource Theory (2002) helps predict which information modalities will interfere, but in the case of head mounted displays (HMDs), the importance of competition for focal attention versus central processing resources in determining dual-task interference remains unclear. We investigated the interference between manual tracking and a word memory task, where words were presented on a HMD, the same display as the tracking task, or audibly. Compared to single-task tracking, performance was impaired by both audio and HMD word presentation, but not by words presented on the same visual plane. This suggests some interference is due to demands on vison itself, not just central resources, and that bottom-up shifts in information seeking may also impair performance. Future research into the best methods of utilizing wearable aids and directing user attention is needed.
