Relative Reward Effects On Operant Behavior: Incentive Contrast,Induction And Variety Effects, Howard Cromwell
Relative Reward Effects On Operant Behavior: Incentive Contrast,Induction And Variety Effects, Howard Cromwell
Howard Casey Cromwell
Comparing different rewards automatically produces dynamic relative outcome effects on behavior. Eachnew outcome exposure is to an updated version evaluated relative to alternatives. Relative reward effectsinclude incentive contrast, positive induction and variety effects. The present study utilized a novelbehavioral design to examine relative reward effects on a chain of operant behavior using auditory cues.Incentive contrast is the most often examined effect and focuses on increases or decreases in behavioralperformance after value upshifts (positive) or downshifts (negative) relative to another outcome. Weexamined the impact of comparing two reward outcomes in a repeated measures design with three ses-sions: a single outcome and …

An investigation of the essential oil (EO) and the crude MeOH extract of a Bhutanese variety of Ajania nubigena using GC/GC-MS and NMR found the following: a) one kg of the dried plant material contained 0.7% w/w EO; b) 44 of the 53 GC-FID peaks of the EO were identified with (3R,6R)-linalool oxide acetate (75.8 %) as the major constituent (chemotype II) and chamazulene as a new sub-chemotype; c) purification of the EO furnished (3R,6R)-linalool oxide acetate (1), chamazulene (2), (E)-2-(2,4-hexadiynylidene)-1,6-dioxaspiro[4,4]non-3-ene (3), and (Z)-2-(2,4-hexadinylidene)-1,6-dioxaspiro[4,4]non-3-ene (4); d) from the crude MeOH extract, four flavonoid compounds: 1-(4-hydroxyphenyl)propan-1-one (5), oxyanin B (6), luteolin …
