“…Recent work, however, gives more support to this measure (Lahtinen et al 2007) or to related measures that combine heart rate and blood pressure (Fredericks et al 2005). Pupillary reactions are also used and are regarded as sensitive for cognitive load variations (Paas et al 2003b;van Gog et al 2009), but have only been used in a limited number of studies (e.g., Schultheis and Jameson 2004). There are, however, indications that the sensitivity of this measure to workload changes diminishes with age of the participants (van Gerven et al 2004).…”

Cognitive load theory, educational research, and instructional design: some food for thought

Cognitive load is a theoretical notion with an increasingly central role in the educational research literature. The basic idea of cognitive load theory is that cognitive capacity in working memory is limited, so that if a learning task requires too much capacity, learning will be hampered. The recommended remedy is to design instructional systems that optimize the use of working memory capacity and avoid cognitive overload. Cognitive load theory has advanced educational research considerably and has been used to explain a large set of experimental findings. This article sets out to explore the open questions and the boundaries of cognitive load theory by identifying a number of problematic conceptual, methodological and application-related issues. It concludes by presenting a research agenda for future studies of cognitive load.

“…Longer task times, higher fixation counts and their average durations have been shown to be reliable indicators of cognitive effort across a variety of tasks (cf. Rayner, 1998;Schultheis and Jameson, 2004;Iqbal et al, 2005; Stanford Poynter Project).…”

This paper reports on the results of a project that aimed to investigate the usability of raw machine translated technical support documentation for a commercial online file storage service. Adopting a user-centred approach, we utilize the ISO/TR 16982 definition of usability -goal completion, satisfaction, effectiveness, and efficiency -and apply eye-tracking measures shown to be reliable indicators of cognitive effort, along with a post-task questionnaire. We investigated these measures for the original user documentation written in English and in four target languages: Spanish, French, German and Japanese, all of which were translated using a freely available online statistical machine translation engine. Using native speakers for each language, we found several significant differences between the source and MT output, a finding that indicates a difference in usability between well-formed content and raw 2 machine translated content. One target language in particular, Japanese, was found to have a considerably lower usability level when compared with the original English.

“…Com relação às fixações do olhar, três medidas podem ser obtidas: 1) Número de fixações, que se refere à quantidade de fixações que são contadas em um determinado período de tempo, ou em uma região específica da tela (interface) ou de um objeto; 2) Tempo de fixação, que consiste no tempo que o participante passou fixando em um mesmo ponto. Segundo alguns autores, quando o tempo de fixação é muito alto, pode significar um aumento da carga cognitiva no usuário (IQBAL et al, 2005;SCHULTHEIS & JAMESON, 2004) e; 3) Dispersão das fixações, que refere-se à quantidade de fixações afastadas das áreas de interesse.…”
