THE MAIN QUESTIONS WE ASKED IN THIS WORK ARE THE FOLLOWING: Where are representations of shape, color, depth, and lighting mostly located? Does their formation take time to develop? How do they contribute to determining and defining a visual object, and how do they differ? How do visual artists use them to create objects and scenes? Is the way artists use them related to the way we perceive the...

Both metacognitive and associative models have been proposed to account for children’s strategy discovery and use. Models based on only metacognitive or only associative mechanisms cannot entirely account for the observed mix of variability and constraint revealed by recent microgenetic studies of children’s strategy change. We propose a new approach where metacognitive and associative mechanis...

Trial-by-trial strategy assessments and a microgenetic design were used to examine 4- and 5-year-olds' learning of rules for solving balance scale problems. The design allowed us to examine simultaneously the contribution to rule learning of distal variables (qualities and knowledge with which children enter the learning situation) and proximal variables (processes that they execute during lear...

One of the main limitations of utilizing optimal wavefront shaping in imaging and authentication applications is the slow speed of the optimization algorithms currently being used. To address this problem we develop a microgenetic optimization algorithm (μGA) for optimal wavefront shaping. We test the abilities of the μGA and make comparisons to previous algorithms (iterative and simple-genetic...

The purpose of this study was to conduct a microgenetic study of the development of the concept of inversion as it applies to multiplication and division inversion problems. The study was modelled on Siegler and Stern’s (1998) study in which Grade 2 participants solved addition and subtraction inversion problems (a + b b) for 6 weekly sessions. In session 7, modified inversion problems (b + a b...

Change is an inevitable, but important aspect of our lives. Football teams travel up and down the leagues, governments come and go, we make the transition from nursery to school, school to college or a job and then from job to job. As change affects everyone and is so endemic, it is crucial that psychologists have an adaptable approach to measure it. Yet, paradoxically in attempting to identify...

This paper begins with a brief survey of the microgenetic process thought of Jason Brown as it has developed from its neuropsychological inception to his more recent neurophilosophy. We then survey some of the arguments and systems of thought that have been put forth since the time of Plato, as they come to bear on the theory of microgenesis and the microgeny of values. Idealism comports surpri...

Abstract The present work examines the role of reflection in supporting development argument skill. Participants who engaged argumentation practice with additional reflective activities outperformed a control group only practice. experimental showed greater gains developing skill – particularly employing evidence to weaken an opposing position. Experimental condition participants also exhibited...
