Alzheimer's dementia (AD) is the most common dementia, Background accounting for more than 60% of all dementia cases. For adults aged >65 years, the incidence rate doubles for every 5 years of increased age; therefore, preserving cognitive function is a pressing issue. Thus, our team screens for AD in older adults with mild cognitive impairment, at 11 public halls in Kashihara City, Japan, and ...

Working memory is a construct of primary relevance to many areas of psychology. Two types of tasks have been used to measure working memory, primarily in different research areas: Complex span tasks are commonly used in behavioral studies in the cognitive and individual-differences literature, whereas n-back tasks have been used more frequently in cognitive neuroscience studies investigating th...

Working memory is an executive function, which involves holding information in mind and mentally working with it (Diamond, 2013). A widely used measure for the assessment of working memory function is the n-back task (Owen et al., 2005). Here, participants are typically instructed to monitor a series of stimuli and to respond whenever a stimulus is presented that is the same as the one presente...

Two studies aiming to investigate the use of cognitive control strategies in the N-Back task are presented. The first study identified a behavioral effect that seemed indicative of participants’ proneness toward using highversus low-control strategies. Two ACT-R models of N-Back implementing the two hypothesized strategies were developed. Model simulations were used to identify the proneness to...

The objective of this paper is to uncover the structure of the back-andforth equivalence classes at the finite levels for the class of Boolean algebras. As an application, we obtain bounds on the computational complexity of determining the back-and-forth equivalence classes of a Boolean algebra for finite levels. This result has implications for characterizing the relatively intrinsically Σn re...

The aim of the present study was to investigate the relations between psychological and physical workload and musculoskeletal neck, shoulder and upper back symptoms. In this longitudinal two-phase cohort study a survey was conducted among non-managerial female elderly-care workers (n = 553). The analyses were based on respondents who were considered free from the respective symptoms at initial ...
