Siddle and Remington [ 37] reconcile these findings by arguing that much of the research that has failed to demonstrate latent inhibition effects has not used appropriate control procedures necessary to establish stimulus specific and associative effects for pre-exposure.
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.
We established Stimuli-SoS as a systematic approach based on well-defined activities.
The established stimuli of ciliary beat frequency, muscarine and ATP, increased cilia-driven particle transport (Figure 3).
Using well established stimuli and tasks from voice-onset time categorical perception learning experiments ([26]; see [2] for review) participants heard two variants of the speech syllable "ba".
As pointed out by McIlvane et al. (2000), learning both routes establishes robust stimulus control of conditional relationships.
For each experiment, one set of wells was treated with 60 mM KCl to determine the responsiveness of the cultures to an established depolarizing stimulus [13].
The strength of the tool images was chosen per participant for both load conditions on the basis of a prescanning session that established the stimulus contrast that generated chance performance in the low-load condition (see Experimental Procedures).
In Experiment 2 we tested this possibility against the alternative possibility that conscious evaluation of stimuli leads subjects to establish peripheral stimulus-response associations and that these SR mappings were responsible for the earlier MCE.
In this paradigm, the first 'locator' stimulus establishes the spatial (and perhaps temporal) origin.
Neuroimaging can help establish how stimuli are discriminated, for example by showing differential activity in regions specifically implicated in phonetic processing.
