“…Furthermore, Drory (1985) reported that a simple task of periodically reporting odometer readings improved driver performance when driving continuously for an extended duration. Recent work by Gershon, Ronen, Oron-Gilad, and Shinar (2009) reported that an interactive cognitive task led to improvements in driving performance when employed as a countermeasure against driver fatigue.…”

“…The result that short-term information processing task demands appear to increase activation is consistent with the predictions of malleable resources theory (Young & Stanton, K Fletcher Task Demands, Resources, and Metacognitive State Dynamics2002b) that workload associated with task performance increases the level of available resources, and is consistent with previous findings that verbal tasks which impose some working memory load can increase activation and driving performance (Atchley et al, 2014;Gershon et al, 2009). The current experiment also potentially clarifies the mechanisms by which these effects are produced.…”

A set of short cognitive, discrimination and tracking tasks has also been shown to increase task engagement and cerebral blood flow velocity, which may index a state of readiness for resource mobilisation (Matthews et al, 2010).…”

The dynamic effects of task demands on resource availability, resource allocation and metacognitive states

Changes in task demands can trigger a complex and dynamic self-regulatory process which influences a range of metacognitive and physiological states. Individuals continuously monitor task cues, the level of task performance and other internal states in order to form an assessment of current task demands. Cognitive-energetic theories propose that individuals possess a finite amount of available resources which can be allocated to meet task demands.Increased task demands will generate an increase in the level of resources allocated in order to maintain task performance, but only up to a point of maximum effort which is determined by the level of available resources. However, while the level of available resources is finite, it is not necessarily fixed. It is generally held that the sustained allocation of resources depletes the level of available resources, so that prior high task demands will reduce the level of available resources and therefore the maximum level of resources allocated to meet current high task demands. Reduced levels of available resources may also cause a compensatory increase in the level of allocated resources at low demand levels in order to protect against possible performance lapses caused by low resource availability.The current thesis proposes that, instead of a general process by which all resource allocation depletes the level of available resources, the allocation of attentional control resources depletes the level of available resources but the allocation of information processing resources provides an opposing short-term increase in the level of available resources. This proposal provides a way of accounting for potentially contradictory empirical data and integrating ego depletion theory and malleable resources theory. The thesis develops a resource-based self-regulatory dynamic control model of the human response to task demands in which the level of available and allocated information processing and attentional control resources both influence and are influenced by current and prior task demands. The model also identifies how the level of available and allocated resources contribute to the metacognitive states of perceived difficulty, effort, activation and valence and the physiological state of pupil diameter. Three experiments were conducted to test predictions arising from the model. Experiments 1 and 2 manipulated the level of task demands within a range of relatively simple, short-term, intermittent cognitive and motor control tasks and Experiment 3 manipulated demand level within a sustained, continuous, and complex control task in order to identify the validity of the proposed model under a range of task conditions. The experiments provided mixed support for the model. The proposal that attentional control demands and information processing demands had opposing effects on the level of available resources was broadly supported by the empirical data which suggests that resource theories need to distinguish the effects of these two types of task demands. However, the ...

“…This was achieved by investigating relative lane position to the roadway dividing line, and the mean standard deviation within the lane. This analysis of lane keeping was similar to Kubose et al (2006), and Gershon et al (2009) Analysis was also conducted on the recall of billboards presented during the drive.…”

“…Drory (1985) reported that a short secondary verbal task of having to periodically report odometer readings did improve driver performance when they were fatigued and underaroused. More recently, Gershon, Ronen, Oron-Gilad and Shinar (2009) reported that an interactive trivia type game had a positive impact on driving performance when drivers began to show signs of under-arousal as induced by a prolonged driving task. In line with what was found by previous work on secondary tasks on drivers who were experiencing task underload, this study sought to investigate the effects of a continuous secondary verbal task, similar to a cell phone conversation, on task performance, and whether or not the benefits of a conversation would outweigh its costs.…”

Summary: It has often been suggested by individuals that engaging in a cell phone conversation would help keep them awake under monotonous conditions where task underload might lead to a decrease in arousal. To further extend laboratory findings of performance in vigilance type tasks while distracted, a monotonous highway driving scenario was designed to test the anecdotal hypothesis of improved performance. Driver performance related to lane keeping and recall memory were studied under distracted and non-distracted conditions. Results of the simulator study were consistent with laboratory findings of performance decrement when dual tasking indicating that the perceived benefits from the secondary conversational task does not outweigh its costs.
