Effects of Aging on Behavioral Measures of Listening Effort
… of listening effort. The most common means of behavioral assessment of listening effort is through use of a dual-task paradigm (DTP), whereby participants perform a “primary” speech-perception task along with a “secondary” task that does not involve speech perception. The two tasks can be …

Behavioral Measures and Ecological Correlates of Vision in Poeciliid Fishes
… I used an optomotor assay to measure the behavioral responses of eight individual P. reticulata (N = 4 males; 4 females) to rotating achromatic stimuli. Unsurprisingly, I found that P. reticulata are better able to perceive stimuli as they increase in contrast and decrease in spatial …

Neurophysiologic and Behavioral Measures of Phonetic Perception in Adult Second Language Speakers of Spanish
… that are present in Spanish and not English. Behavioral and Electrophysiological measures were obtained in response to a continuum of bilabial consonant-vowel (CV) stimuli that differed in voice onset time (VOT) from -50 to 30 ms VOT (/ba/ to /pa/). The -50 ms VOT stimulus was paired with each …

The Cross-Validation of AD/HD Instruments and the Relationship to Neurocognitive and Behavioral Measures
… little overall consistency. The neurocognitive measures used in the study were the Cognitive Assessment System-Basic Battery scales. The socioemotional measures used in the study were two parent-report scales from the BASC-M (Internalizing Problems and Adaptive Skills), and the child report …

Happy Chickens: Novel Physiological and Behavioral Measures of Cumulative Experience in Broilers and Laying Hens
… is difficult to quantify, as no validated measures of cumulative experience exist. Additionally, existing measures of negative animal experience mostly rely on interpretations of animal behavior which can be subjective, time consuming, and difficult to interpret. Therefore, there is …

Electrically Evoked Auditory Potentials Recorded at Three Levels of the Auditory Pathway From Multichannel Cochlear Implant Subjects: Characterization and Comparison to Behavioral Measures
… (EPT). Comparisons between the EPTs and behavioral measures suggest that thresholds of either the Wave V, the Na-Pa complex, or the N1-P2 complex may be used to select stimulus levels that are audible for subjects, although the location of the EPT within the behavioral dynamic range …

Voxel-Based Lesion Symptom Mapping as a Predictor of Motor Impairment after Stroke
… Timed Up and Go, and walking speed were used as behavioral measures in the analysis. Behavioral measures were significantly correlated with lesion location, with lesions in the left superior temporal gyrus, post-central gyrus, and central fissure significantly predicting deficits in the motor …

Exploring field sobriety tests to deter drunk driving
… to validate modified versions of laboratory measures of behavioral impairment from alcohol for use in the field. A total of 195 students at various BAC levels, participated during two outdoor university-sponsored events. In addition to taking nonbehavioral measures of impairment, each subject …

P300 Topographic Differences Between Smokers and Nonsmokers During a Visual Continuous Performance Task
… Signal detection analysis was applied, and behavioral measures of response bias (B"), perceptual sensitivity (A'), hit rate (HR), fake-alarm rate (FA), and median reaction time (RT) were examined. Findings: Withdrawn smokers showed a decreased P300 amplitude relative to the NS and NWS …

Development and Psychometric Validation of the State-Trait Spirituality Inventory
… consisted of paper-and-pencil cognitive and behavioral measures. Cognitive measures were more likely to support convergent/divergent validity than were behavioral measures. A major emphasis in the study was to determine whether state and/or trait spirituality were able to predict current …

Genetic Dissection of Neural Circuits Underlying Value Based Decision Making
… substrates of this process, we developed a behavioral task for mice that required repetition of the processes of action initiation, action selection, and learning. The task is a two-option choice task with stochastic reward delivery and reversals. To map brain areas involved in this type of …

A Behavioral Genetic Study of the Links Between Working Memory and Aspects of Attention in Middle Childhood
… association between working memory and different behavioral aspects of the attention network (i.e., executive attention, alerting attention, and orienting attention), using a twin design. Data were from 131 monozygotic (39% male) and 173 same-sex dizygotic (44% male) twins. Individual differences …
