These paradigms differ in their conceptualization of the discourse.
The aim of Experiment 2 was to investigate whether the unisensory auditory and visual stimuli employed in the associative learning paradigms differ in discrimination difficulty.
However, we were unable to convincingly detect changes in p-Bad in glutamate- vs IGF-I-treated OPCs in vitro, suggesting either that the two paradigms differ in which BH3-only proteins are involved in Bax activation and/or that the reduction in p-Bad in damaged white matter occurs in cells other than oligodendroglia.
Two experimental methods, which have dominated the study of declarative memory in preverbal children with imitation tasks, namely the deferred imitation and elicited imitation paradigm, differ in the amount of physical contact with test stimuli afforded infants prior to a test for long-term recall.
Adopting a perspective in which the paradigms differ quantitatively would make it possible to develop a unified model that accounts for what is observed in both paradigms.
An open question in the literature is the degree to which the results obtained by the two paradigms differ, and if they do, why.
We suggest that seeing prospective and retrospective timing as two paradigms that differ in a quantitative, rather than a qualitative, fashion is a viable hypothesis to account for a difference such as the one observed in the present study.
Our experimental paradigm differed from a conventional Posner task, in that the spatial cues predicted the target location with different probabilities at different times during the experiment, thus requiring the subject to infer CV while accounting for environmental volatility.
The main objective of Experiment 2, therefore, was to investigate whether responsiveness to the aversive properties of ethanol in a CTA paradigm differed as a function of age and sex.
Pashler (1988) and Cowan (2001) both suggested formulas, derived from different multinomial tree models, that might be used to estimate capacity; they differed in the paradigms that they applied.
