By measuring semantic or associative relations between related and unrelated stimulus
pairs, the first word is presented as a prime and the second word as a target.
Thus, two configurations can be used to test results: (1) A Type 2 probe without mask consisting of an undefined novel sample stimulus
and comparison stimuli (defined, undefined from the exclusion probe, and novel undefined stimuli), with the correct response being the novel undefined stimulus
; (2) A Type 4 probe without mask consisting of an undefined sample stimulus
from the exclusion probe and comparison stimuli (defined, undefined from the exclusion probe and novel undefined stimulus
), with the correct response being the undefined stimulus
from the exclusion probe.
Data from 8 participants were removed for the following reasons: five participants fell asleep during the stimulus
presentation; 3 participants showed artifacts in their EEG data due to simultaneously recorded eye movements.
In order to validate the SOR task as a perceptual learning procedure, the explorative behaviour of non-pathological adult rats was recorded in two experimental situations that differed in terms of the degree of similarity of the novel and the familiar stimulus
. The stimuli either differed slightly (Difficult discrimination condition) or more markedly (Easy discrimination condition).
Alternate mapping techniques, involving unevenly spaced stimulation grids and "pseudorandom," rather than systematic, site stimulation have been shown to be reliable when only one stimulus
is delivered to each target site [10, 40].
(2006) and in that conducted by Matos and Flores (2009) the absence of stimulus
control was due to collateral response patterns produced by [t.sup.D] and [t.sup.[DELTA] regular alternation, the same possibility applies to the performances that suggested stimulus
control by signals added to the [t.sup.D] subcycle.
Tests were performed with the four training stimuli and four test stimuli, programming one trial for each stimulus
in the test of each relation.
In both training procedures, the responses were emitted using four buttons of the computer keyboard that corresponded to the position of stimulus
3 After several seconds, have the helper remove the stimulus
, and stop feeding chicken.
Experimental evaluations of the efficacy of choice-based stimulus
preference assessments incorporate reinforcer assessments in which the effects of contingent stimulus
presentation are observed on student behavior (Cannella et al., 2005).
Not really, retorts Stanford economist John Taylor, a stimulus
critic, on his blog.
In Paxton's case, stimulus
money went to a privately held entity that's been in the news before: WatchGuard Video, a Plano-based company that once touted having three state legislators, including Paxton, among its investors.
