In this article, Patrick Slattery challenges the assumptions underlying many educational policy documents, such as the 1994 Report, Prisoners of Time, which, in Slattery 's view, depict time as both an object to control and as a dictator of the linear sequencing that shapes schooling. Slattery argues for a proleptic understanding of time in education. That is, he calls for an understanding that acknowledges how time interconnects with classroom life by providing an overview of various perspectives from classical physics that illuminate the interdependence of the space-time continuum, by addressing the role of personal history in influencing the relationships of students and teachers, and by advocating for curricula that connect to the realities of students' lives. Time has traditionally been incorporated into educational research as a varia ble to be controlled, managed, or manipulated for the purpose of advancing instruc tional objectives, improving classroom management, and enhancing evaluation results. Educational studies of time are rooted in modernist conceptions of segmentation and linear progress. These conceptions assume that isolated parts of complex systems (like schools, people in schools, or curriculum) can be divided into coherent and cohesive segments (like grade levels, control groups, or subject matter disciplines) and measured quantitatively without contamination. The hermetically sealed results can then be studied, generalized, and applied to any other context for the purpose of insuring steady progress and sequential development over time throughout the entire system. This philosophy of modernity has resulted in an exaggerated emphasis on manipulation of time: time management, timed tests, wait time, time on task, quantifiable results over time, time
This study investigates the neural mechanisms of mood induced modulation of cognition, specifically, on reality monitoring abilities. Reality monitoring is the ability to accurately distinguish the source of self-generated information from externally-presented contextual information. When participants were in a positive mood, compared to a neutral mood, they significantly improved their source memory identification abilities, particularly for self-generated information. However, being in a negative mood had no effect on reality monitoring abilities. Additionally, when participants were in a positive mood state, they showed activation in several regions that predisposed them to perform better at reality monitoring. Specifically, positive mood induced activity within the medial prefrontal cortex (mPFC) and posterior cingulate cortex (PCC) was associated with improvements in subsequent identification of self-generated information, and positive mood induced activation within the striatum (putamen) facilitated better identification of externally-presented information. These findings indicate that regions within mPFC, PCC and striatum are sensitive to positive mood-cognition enhancing effects that enable participants to be better prepared for subsequent reality monitoring decision-making.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
