Despite its significance, the central executive is the least explored component of working memory, particularly in complicated contexts. Exp. 1 investigated the role of executive control of working memory in situation awareness in a real-life driving simulation. Exp. 2 examined the extent to which taxing the central executive might affect situation awareness. High, Medium, and Low Situation Awareness groups were formed as assessed using the Situation Awareness Global Assessment Technique. Executive function was measured using several tests. Results from Exp. 1 demonstrated that the Low Situation Awareness group performed significantly worse on all executive function tasks compared to High and Medium Situation Awareness groups. Findings from Exp. 2 suggested that concurrent load on the central executive dramatically affected the Low Situation Awareness group but not the High Situation Awareness group: the former had significantly more driving violations under central executive load.

Saccade Generation

The Findlay & Walker model of saccade generation does not appear to account fully for saccadic performance deficits observed in schizophrenia patients. It would be enhanced by inclusion of a frontally mediated, central executive function system. A review of schizophrenia patients' antisaccade task deficits provides an example of the role of higher cortical functioning in saccade generation.

Abstract The main objective of this study was to examine whether children’s ability to justify their action predictions in terms of mental states is related, in a similar way as the ability to predict actions, to such aspects of executive function (EF) as executive control and working memory. An additional objective was to check whether the frequency of different types of justifications made by children in false-belief tasks is associated with aforementioned aspects of EF, as well as language. The study included 59 children aged 3-4 years. The ability to predict actions and to justify these predictions was measured with false-belief tasks. Luria’s hand-game was used to assess executive control, and the Counting and Labelling dual-task was used to assess working memory capacity. Language development was controlled using an embedded syntax test. It was found that executive control was a significant predictor of the children’s ability to justify their action predictions in terms of mental states, even when age and language were taken into account. Results also indicated a relationship between the type of justification in the false-belief task and language development. With the development of language children gradually cease to justify their action predictions in terms of current location, and they tend to construct irrelevant justifications before they begin to refer to beliefs. Data suggest that executive control, in contrast to language, is a factor which affects the development of the children’s ability to justify their action predictions only in its later phase, during a shift from irrelevant to correct justifications.

Frontal Lesions

A major problem in analysing the executive processes that seem to depend upon the prefrontal cortex stems from the absence of a well developed cognitive model of such processes. It is suggested that the central executive component of an earlier model of working memory might provide a suitable framework for such an analysis. The approach is illustrated using one proposed component of executive control, namely the capacity to combine two concurrent tasks. The application of the approach to patients suffering from Alzheimer’s disease, and patients with acquired brain damage is discussed. Finally, a study is described in which the dual task performance of patients with known frontal lesions is shown to be associated with observed behavioural problems. The paper concludes with the discussion of the prospects for extending the approach to include a range of other executive processes, and to the way in which such an analysis may subsequently lead to a more integrated model of the central executive, and a better understanding of its relationship to the prefrontal cortex.

Simulation is an educational approach well suited to development of knowledge and decision-making skills for emergent or infrequent scenarios. Electronic Health Record (EHR) based simulation, in which participants retrieve information from a simulated EHR, provides an authentic training environment with fidelity to the typical clinical decision-making process and has been associated with enduring changes in EHR use patterns. However, we do not know whether these behavior changes reflect better decision-making. We aimed to develop a measure of pediatric resident performance in an EHR based simulation using the Situation Awareness Global Assessment Technique (SAGAT).
