Vi. Sensitive Periods
This chapter reviews sensitive periods in human brain development based on the literature on children raised in institutions. Sensitive experiences occur when experiences are uniquely influential for the development of neural circuitry. Because in humans, we make inferences about sensitive periods from evaluations of complex behaviors, we underestimate the occurrence of sensitive periods at the...
متن کاملEvolved Sensitive Periods in Learning
In this paper we study age-varying plasticities across different components in an artificial neural network performing a reinforcement learning task. An evolutionary algorithm is given the task of mapping the age of agents to the plasticity levels of different network components. The results show that patterns of plasticity resembling biological sensitive periods appear, and that these periods ...
متن کاملThe computational modeling of sensitive periods.
In the continuing debate on sensitive periods, Tyler (this issue) argues for a mechanistic explanation of sensitive periods in development, rather than simply deriving a relationship between plasticity and age. Armstrong et al. (2005) endorse convergent approaches to assess types of plasticity, including the use of behavioral evidence, neurophysiological evidence, functional magnetic resonance ...
متن کاملThe Cerebellum, Sensitive Periods, and Autism
Cerebellar research has focused principally on adult motor function. However, the cerebellum also maintains abundant connections with nonmotor brain regions throughout postnatal life. Here we review evidence that the cerebellum may guide the maturation of remote nonmotor neural circuitry and influence cognitive development, with a focus on its relationship with autism. Specific cerebellar zones...
متن کاملThe computational modelling of sensitive periods
Typesetting note: We have used Greek symbols in the text but we have found these sometimes do not appear if the document is opened on a computer loaded with different fonts. The symbols are Δ (upper case delta) and ε (epsilon). These symbols appear on p.3, paragraph 4, line 2 (below equation 1): " where a i is the activation of the sending unit and a j is the activation of the receiving unit, w...
