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...

This publication is composed of three interviews conducted with Jason W. Brown a few years ago. The first is concerned with early influences that shaped his development of a theory of “microgenesis”. The second focuses on evolutionary principles apparent in brain development and mental processes. In the third interview, Brown discusses the internal processual structure of the “mind/brain state”...

Barth and Paladino (2011) argue that changes in numerical representations are better modeled by a power function whose exponent gradually rises to 1 than as a shift from a logarithmic to a linear representation of numerical magnitude. However, the fit of the power function to number line estimation data may simply stem from fitting noise generated by averaging over changing proportions of logar...

In this chapter, we report five beginning undergraduate students' understanding of the 3-D structure of DNA, and the use of gesture and analogy to enhance their 3-D visualization of DNA structure. Through clinical interview-cum-teaching sessions we first recapitulated their background knowledge of basic biology and chemistry prerequisites. We then proceeded to a microgenetic study of the studen...

Two successive, spatially overlapping human faces were exposed for recognition with SOAs ranging from 20 to 160 msec. The subjects effectively perceived one face, which at short SOAs mostly resembled the first stimulus and with increasing SOAs gradually shifted towards the appearance of the second, dimmer stimulus. These results replicated those from the study by Calis, et al, and extended them...

This article discusses the potential impact of microgenetic theory, as elaborated by Jason W. Brown, on the neurosciences. Since it is based on and incorporates methods and premises from such disparate areas as evolutionary biology, neuropsychology, neurology, the philosophy of mind, and even Whiteheadian process metaphysics, microgenetic theory is not easy to grasp, but it proves to be a theor...

This case study explores how 12-13-year-old students encounter proportional reasoning while working with geometric patterning tasks using concrete materials. The focus is on the students’ use of spontaneous concepts when first dealing such patterns in context collaborative work. Based video recordings a single lesson, microgenetic analysis was performed to identify learning trajectories, starti...
