The relation between task properties, system performance and operator mental load in supervisory control is investigated using an artificial model of a pasteurisation plant. The relation is evaluated using the degree of automation which is based on the relative weights of the manually controlled tasks. Three ways of calculating task weights are investigated, based on 1) the mental load perceive...

Intentional forgetting of unwanted items is effortful, yet directed seems to improve when a secondary task performed. According the cognitive load hypothesis forgetting, allocating attentional resources another improves by restricting encoding to-be-forgotten (TBF) items. Alternatively, it might be that anything makes studying more difficult will encourage greater effort perform well and theref...

Parkinson's disease patients and control subjects performed a simultaneous bilateral reach-to-grasp task to two different sized objects and then pulled the two objects apart. The first phase of the task (reaching-to-grasp) allowed us to examine the issue that impairments in simultaneous movements for Parkinson's disease patients are seen in some tasks but not in others. It is suggested that the...

BACKGROUND The flexion relaxation phenomenon (FRP) is an interesting model to study the modulation of lumbar stability. Previous investigations have explored the effect of load, angular velocity and posture on this particular response. However, the influence of muscular fatigue on FRP parameters has not been thoroughly examined. The objective of the study is to identify the effect of erector sp...

The development process involved developers contribution based his/her cognitive thinking in the real time process. The developer’s performance is dynamic as per their cognitive load. The cognitive load is un-deterministic as well hidden and integrated in the developer’s process. This paper attempt to identify software developer cognitive measure which influences the development process using n...

The relative-coding hypothesis of temporal discrimination asserts that humans learn to respond to the relative duration of stimuli ("short" and "long"). The most frequently used procedure to test the hypothesis is the double bisection task. In one task, participants learn that red and green are the correct comparisons following 2s (short) and 5s (long) samples respectively. In another task, par...

Traditionally, the visual enumeration of a small number of items (1 to about 4), referred to as subitizing, has been thought of as a parallel and pre-attentive process and functionally different from the serial attentive enumeration of larger numerosities. We tested this hypothesis by employing a dual task paradigm that systematically manipulated the attentional resources available to an enumer...

The hypothesis that working memory is crucial for reducing distraction by maintaining the prioritization of relevant information was tested in neuroimaging and psychological experiments with humans. Participants performed a selective attention task that required them to ignore distractor faces while holding in working memory a sequence of digits that were in the same order (low memory load) or ...
