Reward delivery was concomitant with the compound presentation of 2 cues, consisting of a 2-sec 65 dB auditory tone and illumination of the food magazine, that were designed to serve as explicit secondary or conditioned reinforcers during the tests for reinstatement (see below).
For liquid stimuli, cotton applicators (Puritan Medical Products, Guilford, ME, USA) were saturated with the pure compound before presentation to the animal.
Such an inclusion would have clarified whether patients have a general deficit in learning under conditions of confusion between single and compound stimulus presentation.
During the second phase, the lever was available throughout the whole session and an elevation score was calculated for each stimulus as the mean number of responses during each component or compound stimulus presentation minus the mean number of responses during the 30-s prestimulus interval for that specific stimulus.
During the actual test (Phase 3, parts 2 and 3), the EF compound was presented twice, unreinforced, followed by four unreinforced presentations of the components E and F, intermixed with four unreinforced presentations of the compound EF.
Automatically generated HTML, PDF and ASCII presentations of compound sets are identified by their set number.
Cephalic presentation included vertex, face and brow; non-cephalic included breech, shoulder, cord, compound and other (unknown presentation excluded).
Plastics Additives & Compounding highlights some of the presentations related to additives and compounding.
A few patients, either with typical or atypical clinical presentation, are compound heterozygous for the GAA expansion and a micromutation.
Further evidence for access to constituent meanings of transparent but not opaque compounds comes from a cross-modal priming study in which visually presented transparent compound words were primed by the prior auditory presentation of both first and second compound constituents and vice versa, but no such effects were observed for opaque compounds (Zhou & Marslen-Wilson, 2000).
