Sentence examples for by the dynamic developmental from inspiring English sources
One such possible causal pathway contributing to the heterogeneity of ADHD includes altered dopaminergic function as described by the dynamic developmental theory put forth by Sagvolden [ 35].
In addition, as previously suggested by the dynamic developmental theory of ADHD, it will be of great importance to investigate how environmental factors (e.g., stress) modulate the above DA pathways and expression of the behavioural deficits in SHR [ 41].
The present findings may be explained by a short delay gradient in the -C and -HI groups, resulting in no association between the stimulus and the response-produced reinforcer, as predicted by the dynamic developmental theory [ 19].
Perhaps Sagvolden et al's model is much broader in scope, where ADHD is just one symptom of a larger constellation of phenotypes – including conduct disorder and adult antisocial behavior – that can be explained by the dynamic developmental behavioral theory.
The results support the hypothesized steeper and shorter delay-of-reinforcement gradient in the animal model, and provided some support for the increased behavioral variability suggested by the dynamic developmental theory of ADHD: Behavior was more variable initially, decreased somewhat slower, and settled into comparable levels of variability only with extended training.
Compromised dopamine neuronal firing could account for decreased dopamine function in target areas as proposed by Sagvolden et al [ 20] in the dynamic developmental theory of ADHD.
The results were, generally, in line with predictions from the dynamic developmental theory of ADHD by indicating that reinforcers were less efficient in the ADHD group than in the non-ADHD group.
According to the dynamic developmental behavioral theory proposed by Sagvolden et al, a hypofunctioning mesolimbic dopamine system is largely responsible for producing alterations in behavioral reinforcement and extinction, which, in turn, disrupts learning processes.
Overall, the results were in line with the predictions from the dynamic developmental theory of ADHD by indicating that reinforcers were less efficient in the ADHD group than in the non-ADHD group in establishing stimulus control and predictable responding, due to a shorter delay-of-reinforcement gradient.
The Dynamic Developmental Theory (DDT) of ADHD has been developed by Sagvolden and colleagues over the past 20 years and has been the subject of a recent major review process [ 11].
We propose that the transport of mRNAs encoded by these genes into the dendrites allows their expression to be regulated on a local scale during the dynamic developmental processes of dendrite outgrowth, branching, and/or remodeling.
