There is a speed-accuracy trade-off in perception. The ability to quickly extract sensory information is critical for survival, while extended processing can improve our accuracy. It has been suggested that emotions can change our style of processing, but their influence on processing speed is not yet clear. In three experiments, combining online and laboratory studies with different emotion induction procedures, we investigated the influence of both affective states, manipulated with music, and individual traits in sensory-processing sensitivity on the ability to rapidly segregate two visual flashes. Across studies, the musical manipulations pushed participants towards either rapid or slow processing. Individual variations in sensory-processing sensitivity modulated these effects. Our findings demonstrate that affective states, influenced by music, can shift the balance between fast and slow visual processing, altering our perceptual experience. These results also emphasise the interaction of individual traits in sensory processing and affective states.

Graduate student literature review: Integrating concepts of animal welfare and health-related quality of life for pre-weaned dairy calves.

J Dairy Sci

Département des Sciences Cliniques, Faculté de Médecine Vétérinaire, Université de Montréal, 3200 rue Sicotte, St-Hyacinthe, QC, J2S 2M2, Canada. Electronic address:

Dairy calf welfare assessment tools focusing on the pre-weaning period have been proposed in recent research. Despite the existence of these tools, assessing the welfare and health-related quality of life (HRQoL) of dairy calves remains challenging. These difficulties may stem from the complexity of assessing all dimensions of calf welfare and the validity, reliability, and feasibility of the indicators used in assessment tools.

Background: Nearly 20% of US cancer survivors develop cardiovascular disease (CVD) from cardiotoxic cancer treatments. Patients and providers may consider alternative treatments to lower cardiotoxicity risk, but these may be less effective at preventing relapse/recurrence, presenting a difficult tradeoff.

Aims: This study explored survivors' cancer treatment decision-making when weighing this tradeoff.

The role of dynamic shape cues in the recognition of emotion from naturalistic body motion.

Atten Percept Psychophys

Human observers can often judge emotional or affective states from bodily motion, even in the absence of facial information, but the mechanisms underlying this inference are not completely understood. Important clues come from the literature on "biological motion" using point-light displays (PLDs), which convey human action, and possibly emotion, apparently on the basis of body movements alone. However, most studies have used simplified and often exaggerated displays chosen to convey emotions as clearly as possible.

Affective polarization in a word: Open-ended and self-coded evaluations of partisan affect.

PLoS One

January 2025

Department of Political Science, University of California, Davis, Davis, California, United States of America.

The literature finds that partisanship drives negative emotional evaluations of out-partisans. Yet, scholars base these insights on measures-like thermometers, candidate evaluations, and social-distance measures-that discount the sentiment attached to individuals' negative attitudes. We introduce a unique measure of affect capturing the motivation underpinning partisans' attitudes.
