Anticipatory Behaviour During the Approach to Feeding Times as a Measure of Horse Welfare.
Animals (Basel)
December 2024
School of Life Science, Wrexham Glyndŵr University Northope Campus, Holywell Road, Northop, Mold CH7 6AA, UK.
Anticipatory behaviour is increasingly being recognised as a measure of animal welfare. This behaviour is linked to reward sensitivity, which reflects the balance of positive and negative experiences. This study examined anticipatory behaviour in horses fed either ad libitum or rationed diets, aiming to identify differences in behaviour patterns during the periods of one hour immediately before and after feeding.

Background: Motivated behaviors vary widely across individuals and are controlled by a range of environmental and intrinsic factors. However, due to a lack of objective measures, the role of intrinsic extrinsic control of motivation in psychiatric disorders remains poorly understood.
Methods: We developed a novel multi-factorial behavioral task that separates the distinct contributions of intrinsic extrinsic control, and determines their influence on motivation and outcome sensitivity in a range of contextual environments.
A Semi-Virtual Trier Social Stress Test (SV-TSST).
Psychoneuroendocrinology
December 2024
Department of Psychology, University of Texas at Austin, Austin, TX, USA. Electronic address:
The Trier Social Stress Test (TSST) is a strategy for inducing acute psychological stress and increases in glucocorticoid levels. Here we describe the methodology and implementation of a Semi-Virtual Trier Social Stress Test (SV-TSST) which combines the control of a laboratory environment with reduced need for in-person logistical support and enhanced social distancing without the need for specialized equipment. During the SV-TSST, the participant is guided through the baseline, anticipatory, challenge, and recovery phases of the test by an in-person experimenter.

December 2024
Department of Research and Development, University of Teacher Education Bern, Bern, Switzerland.
Background: Teaching is a genuinely social and highly demanding task. Drawing on Porges' phylogenetic polyvagal theory with three evolved systems and three associated behavioral responses (social engagement, mobilization, and immobilization), we investigated teachers' heart rate and heart rate variability in social interactions using ambulatory assessments.
Methods: We continuously measured heart rate and heart rate variability of 42 apparently healthy teachers on a work and leisure day with ambulatory electrocardiogram.
Pelvic floor muscle activation in response to pressure stimuli applied to the vulvar vestibule: an observational study comparing women with and without provoked vestibulodynia.

December 2024
School of Psychology, Faculty of Arts and Sciences, Queen's University, Kingston, K7L 3N6, Canada.
Background: The nature of pelvic floor muscle (PFM) involvement in provoked vestibulodynia (PVD) is poorly understood.
Aim: We aimed to determine if PFM electromyographic (EMG) activity in anticipation of or response to pressure applied to the posterior vaginal fourchette differs between those with and without PVD, and if the magnitude of PFM response is associated with pressure pain sensitivity, psychological or psychosexual function.
Methods: This was an observational case-control study.
