Hemodynamic profile, compensation deficit, and ambulatory blood pressure (2018)

Ottaviani, Cristina; Shapiro, David; Goldstein, Iris B.; James, Jack E.; Weiss, Robert

Abstract:

This study hypothesized that physiologically grounded patterns of hemodynamic profile and compensation deficit would be superior to traditional blood pressure reactivity in the prediction of daily-life blood pressure. Impedance cardiography-derived measures and beat-to-beat blood pressure were monitored continuously in 45 subjects during baseline and four tasks. Ambulatory blood pressure measures were obtained combining data. from one work day and one off day. The mediating effects of gender and family history of hypertension were considered. Only gender was significantly associated with hemodynamic profile. Regression analysis indicated that typical reactivity measures failed to predict everyday life blood pressure. After controlling for gender and baseline blood pressure, hemodynamic patterns during specific tasks proved to be strong predictors, overcoming limitations of previous reactivity models in predicting real-life blood pressure.

Stress among parents of children with and without autism spectrum disorder: a comparison involving physiological indicators and parent self-reports (2018)

Stress among parents of children with and without autism spectrum disorder: a comparison involving physiological indicators and parent self-reports (2018)

Padden, Ciara; James, Jack E.

Abstract:

Parents of children with Autism Spectrum Disorder (ASD) have been reported as experiencing higher levels of stress and poorer physical health than parents of typically developing children. However, most of the relevant literature has been based on parental self-reports of stress and health. While research on physiological outcomes has grown in recent years, gaps still exist in our understanding of the physiological effects, if any, of stress related to parenting a child with ASD. The present study compared parent-reported stress, anxiety, and depression, as well as selected physiological measures of stress (i.e., cortisol, alpha-amylase, and ambulatory blood pressure and heart rate) between matched groups of parents of children with (N = 38) and without (N = 38) ASD. Participants completed questionnaires, collected saliva samples for the purpose of measuring cortisol and alpha-amylase, and wore an ambulatory blood pressure monitor for 24 h. Parents of children with ASD reported sign...

The interfering effect of emotional stimulus functions on stimulus equivalence class formation: implications for the understanding and treatment of anxiety (2009)

Tyndall, Ian T.; Roche, Bryan; James, Jack E.

Abstract:

The present experiment examined the effects of respondently conditioned emotional functions on the formation of stimulus equivalence relations. Fifty-seven participants were exposed to a stimulus-pairing procedure that paired six nonsense syllables with aversive images, and a further six stimuli with neutral images. A second phase established different operant response functions for one aversive CS and one neutral CS. In Phase 3, 45 of the 57 participants demonstrated a transfer of the established operant response to stimuli sharing respondent functions, thereby demonstrating the formation of two functional classes. Using a between-subjects design, participants were then exposed to a conditional discrimination training and testing protocol designed to establish two three-member stimulus equivalence relations using either six aversive or six emotionally neutral CSs as stimuli. Participants required significantly more testing trials to form stimulus equivalence relations when all stim...

The relation between stimulus function and equivalence class formation (2004)

The relation between stimulus function and equivalence class formation (2004)

Tyndall, Ian T.; Roche, Bryan; James, Jack E.

Abstract:

Fifty participants were exposed to a simple discrimination-training procedure during which six S1 functions were established for six arbitrary stimuli, and S2 functions were established for a further six stimuli. Following this training, each participant was exposed to one of five conditions. In the S1 condition, participants were exposed to a stimulus equivalence training and testing procedure using only the six S1 stimuli as samples and comparisons. In the S1/S2 condition, participants were exposed to the same training and testing sequence as in the S1 condition, the difference being that three S1 and three S2 stimuli were used as sample and comparison stimuli, with each set of three corresponding to the trained equivalence relations. In the S1/S2 mixed condition, the S1 and S2 stimuli were assigned to their roles as samples and comparisons in a quasi-random order. In the S2 condition, all six S2 stimuli were used. The no-function condition served as a control condition and employ...
