In measurement and evaluation for a cognitive performance carried out on various tasks can use objective and subjective measurement tools. This study aims to review research on measuring instruments and provide its potential to be used in research related to cognitive ergonomics. The method that is used in this study is a review of article literature on studies that are subjective and objective measurement tools. the results of this study indicate that in each study usually does not only use one measuring instrument, to validate measurements, but another measurement tool is also used. And in research usually uses subjective and objective measurement tools for the same task.

BACKGROUND: Mothering and caring for children have been associated with a decrease in mothers' wellbeing. Limited research has been conducted from the ergonomics perspective of mothering and caring for children due to the belief that being a mother is not considered an occupation. OBJECTIVE: To observe the ergonomics of mothering and caring for children (ergoMOMics) among Indonesian mothers and the prevalence of related musculoskeletal symptoms (MSS). PARTICIPANTS: Five hundred and twenty-five Indonesian mothers. METHOD: The prevalence of MSS was assessed using Nordic Body Map questionnaire. An adapted questionnaire on mothering and child care activities and their consequences were also used. RESULTS: Most Indonesian mothers reported some negative consequences of mothering and child care activities, including MSS in the back (50%), neck (26%), and upper shoulder (43%). Demographic data that significantly influences MSS includes the domicile category and help from others. Mothers in large cities reported higher MSS than those residing in small-to medium-sized cities (t (523) = 7.43, ρ < 0.01). The help of family members (commonly children's grandparents) significantly increased reported MSS (F(2, 524) = 3.57, ρ = 0.02). A specific child care activity that influences MSS is the lifting for children. CONCLUSIONS: Mothering and child care are very demanding activities that can result in MSS. Therefore, steps must be taken to prevent and overcome these symptoms.
