A Comparison of Brief Versus Extended Paired-Choice Preference Assessment Outcomes.
… procedures. A total of 17 food and leisure paired-choice preference assessments were administered to 10 subjects in order to evaluate the extent to which the results of a brief (i.e., single-session) assessment correspond with those from more extended procedures (i.e., 5 sessions). Eleven …

COMPARING FUNCTION-BASED MULTIPLE STIMULI WITHOUT REPLACEMENT AND PAIRED-CHOICE PREFERENCE ASSESSMENT RESULTS
… without replacement (MSWO) assessment and a paired-choice assessment (PC) were compared to determine whether the same stimuli options were identified. The two assessment procedures were conducted in a school setting with three participants who engaged in frequent problem behavior. An …

Biology and Host-Range Testing of <i>Laricobius kangdingensis</i> sp. n. (Coleoptera: Derodontidae), a Newly Discovered Predator of Hemlock Woolly Adelgid, <i>Adelges tsugae</i> Annand (Homoptera: Adelgidae)
… sp. n. appears to be host-specific. In paired-choice feeding tests, adults consumed significantly more HWA than two other adelgid species [eastern spruce gall adelgid, <i>Adelges abietis</i> (L.), and pine bark adelgid, <i>Pineus strobi</i> (Hartig)], the pine needle scale, <i>Chionaspis …

The relative contributions of preference and functionality in noncontingent reinforcement schedules
… Preference values were evaluated through paired-choice and competing stimulus assessments. Three preferred stimuli were selected for NCR-Preferred experimental conditions, based on varied levels of preference (i.e., highest, lowest, moderate). The preference was confirmed to be …

An Evaluation of the Validity of Vocal Preference Assessments Used with Adults with Developmental Disabilities
… provide individuals with an opportunity to make choices and thus, increase their autonomy. Furthermore, preference assessments are used to identify stimuli that can be used as reinforcers in behavior change programs. Two studies were conducted to examine the validity of vocal preference …

Quantity versus quality : the opportunity to choose back-up reinforcers in a token economy
… contingent on academic task completion. A paired-choice preference assessment was conducted followed by a reinforcer assessment using a combined reversal and multi-element design. The purpose of these procedures was to determine whether higher rates of responding would occur during …

Influence of dietary nutrients on life history-related traits of black flies and mosquitoes
… Culicidae) on artificial nectar and honeydew. Paired choice experiments showed that the black flies forage more frequently from high calorie diets, which contained melezitose, or those diets that contained amino acids, compared to low calorie melezitose-free diets or amino acid-free diets. The …

Sensory exploitation and condition indication may explain red pelvic spines in the brook stickleback Culaea inconstans
… on their pelvic spines. I presented fish with a paired choice between a red versus an orange, yellow, green, blue, or purple bead, and recorded the proportion of bites at each color. I tested for sexual dimorphism in pelvic spines and made observations on their use by territorial males in …

Biology of Laricobius nigrinus Fender (Coleoptera: Derodontidae) and its potential as a biological control agent of the hemlock woolly adelgid, Adelges tsugae Annand (Homoptera: Adelgidae) in the eastern United States
… weeks. Laricobius nigrinus is host specific. In paired-choice and no-choice oviposition tests, L. nigrinus laid more eggs in HWA ovisacs than other test species. Laricobius nigrinus consumed more eggs of HWA than eggs of Adelges piceae (Ratzeburg) and Pineus strobi (Hartig) but not of Adelges …

Biological Studies and Evaluation of Scymnus Coniferarum, a Predator of Hemlock Woolly Adelgid from Western North America
… S. coniferarum were conducted in a series of no-choice and paired-choice feeding, oviposition, and development studies. Scymnus coniferarum adults fed on all adelgid species, and completed development on HWA and Adelges piceae Ratz. Scymmnus coniferarum oviposition was extremely low. In the final …
