Measures Of Performance

In many human performance tasks, researchers assess performance by measuring both accuracy and response time. A number of theoretical and practical approaches have been proposed to obtain a single performance value that combines these measures, with varying degrees of success. In this report, we examine data from a common paradigm used in applied human factors assessment: a go/no-go vigilance task (Smith et al., 2019). We examined whether 12 different measures of performance were sensitive to the vigilance decrement induced by the design, and also examined how the different measures were correlated. Results suggest that most combined measures were slight improvements over accuracy or response time alone, with the most sensitive and representative result coming from the Linear Ballistic Accumulator model. Practical lessons for applying these measures are discussed.

BackgroundDespite 30 years of research, some surprisingly fundamental gaps remain in our understanding of schizophrenic input dysfunctions.MethodIn a provisional test of a ‘hyperattention’ hypothesis, schizophrenic patients and control subjects performed a behavioural test that was adapted from a paradigm originally developed for characterising vigilance or sustained attention in animals. On this computerised operant testing procedure, subjects discriminated between signals of various salience and non-signal presentations. Hits and correct rejections resulted in monetary rewards while misses and false alarms entailed monetary costs.ResultsData from in-patients with schizophrenia and age, education and gender-matched controls support hypotheses not only about hyperattentional dysfunctions in schizophrenia with respect to overall signal detectability but also in terms of resistance to the vigilance decrement that normally occurs over trials.ConclusionsThe theoretical importance of impairments of this sort are discussed with respect to the cognitive and perceptual consequences of hypervigilance and ‘input dysfunction’.

Over Time

Effectively mitigating the vigilance decrement (the decrease in performance on tasks requiring sustained attention over time) is one of the most important human factors problems studied today. Despite this, the underlying theory of vigilance and its failings are still disputed. The two primary theories espoused by researchers today are a cognitive resource theory of vigilance and a mindlessness theory of vigilance. This literature review examines the literature investigating points of conflict between these theories, revealing that the majority of experimental research supports a cognitive resource theory of vigilance. Additionally, we examine research investigating the effect of active rest breaks on cognitive and affective restoration. The literature available on cognitive restoration does not support the suggestion that active rest breaks help restore vigilance-relevant cognitive resources more effectively than passive rest breaks. The research does however, support the proposition that more active rest breaks can reduce stress and increase affect. The potential for increasing worker well-being with more active breaks warrants additional research.

Over Time

Robertson, Manly, Andrade, Baddeley, and Yiend (1997) proposed that the decline in performance efficiency over time in vigilance tasks (the vigilance decrement) is characterized by “mindlessness” or a withdrawal of attentional effort from the monitoring assignment. We assessed that proposal using measures of perceived mental workload (NASA-TLX) and stress (Dundee Stress State Questionnaire). Two types of vigilance task were employed: a traditional version, wherein observers made button-press responses to signify detection of rarely occurring critical signals, and a modified version, developed by Robertson et al. to promote mindlessness via routinization, wherein button-press responses acknowledged frequently occurring neutral stimulus events and response withholding signified critical signal detection. The vigilance decrement was observed in both tasks, and both tasks generated equally elevated levels of workload and stress, the latter including cognitions relating to performance adequacy. Vigilance performance seems better characterized by effortful attention (mindfulness) than by mindlessness. Actual or potential applications of this research include procedures to reduce the information-processing demand imposed by vigilance tasks and the stress associated with such tasks.
