چکیده
The Cognitive Failures Questionnaire (CFQ) is used in ergonomics research to measure behavioural problems associated with attentiveness and memory in everyday life. CFQ scores have been related to constructs such as accident proneness and outcomes such as human error and psychological strain. The two-year test-retest reliability of the CFQ is reported together with the findings of factor analyses of CFQ data from 535 respondents. Evidence for the predictive and criterion validity and internal reliability of the CFQ is provided. Psychological strain was measured concurrently with CFQ on both testing occasions, two years apart. The test-retest reliability of the summated CFQ score was found to be 0.71, while for the General Health Questionnaire (GHQ-12) strain measure it was 0.32.The relative variance stability was five times greater for the CFQ than the GHQ, indicating that scores on these questionnaires are not covariates. The use of the CFQ as a measure of cognitive control capacity is also discussed.

The psychophysical relationship between the magnitude of pressure on thirteen test locations of twenty healthy subjects' feet with four probe areas at three indentation speeds and the corresponding perceived sensations were analyzed. The dependency of pressure pain thresholds (PPT) on area, A, and speed, v, can be mathematically modeled in the form, PPTi = [ai + bLn(v)]Aβi = 1,2...13 where β an...

The present experiment tested 60 individuals on a multiple screen, visual target detection task. Using a within-participant design, individuals received no-cue augmentation, an augmenting tactile cue alone, an augmenting auditory cue alone or both of the latter augmentations in combination. Results showed significant and substantive improvements in performance such that successful search speed ...

Despite the potential dangers of clinical tasks being forgotten, few researchers have investigated prospective memory (PM) – the ability to remember to execute future tasks – in health-care contexts. Visual cues help people remember to execute intentions at the appropriate moment. Using an intensive care unit simulator, we investigated whether nurses' memory for future tasks improves when visua...

We report results from a 1-year field study (N = 80) on user interactions with regenerative braking in electric vehicles. Designed to recapture energy in vehicles with electric powertrains, regenerative braking has an important influence on both the task of driving and energy consumption. Results from user assessments and data from onboard data loggers indicate that most drivers quickly learned...

Due to typical physiological changes with age, older individuals are likely to have different perceptual responses to and different needs for driver–seat interface design. To assess this, a study was conducted in which a total of 22 younger and older participants completed six short-term driving sessions. Three subjective ratings (comfort, discomfort and overall) were obtained, along with 36 dr...
