Stimulus definition in conditional discriminations
Open accessAbstract
With a customary arrangement of three horizontally aligned stimulus/response keys, two rhesus monkeys learned conditional hue and line discriminations—an “identity‐matching” procedure. First, sample stimuli were always presented on the center key, and comparison stimuli were presented on the two side keys. Next, the sample was allowed to appear on any one of the three keys, with the comparisons on the remaining two. The change from fixed to variable sample and comparison locations caused the horizontal and vertical lines to lose control over the animals' responses; the conditional line discrimination deteriorated. This was not true for the red and green hues; the conditional hue discrimination remained intact. Accurate description of controlling stimuli in a matching‐to‐sample procedure may therefore require that their spatial location be specified.

Later research found that formal properties of stimuli, such as location, can exert control over responding to the point of inhibiting symbolic learning.
“Later, researchers found that formal properties of the stimuli, such as its location, may exert control over responding to the point of inhibiting symbolic learning (Iversen et al., 1986;Lionello & Urcuioli, 1998).”
From A Process-Based Analysis of Cognitive Defusion in Acceptance and Commitment Therapy (2023) · cites this paper as Iversen et al., 1986
The Results and Discussion report that changing stimulus locations disrupted the monkeys’ conditional line discrimination, while hue discrimination remained intact. This supports the claim that location can control responding, but the paper does not establish that location inhibited symbolic learning; it measured matching-to-sample performance. (LLM, conf=0.85)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
