Higher rewards lead to more accurate flower detection and increased contrast sensitivity in the bumblebee Bombus terrestris

This study shows that higher sucrose rewards improve bumblebee contrast sensitivity and target detection accuracy, while the pesticide imidacloprid reduces accuracy without affecting response latency.

Binocular visual input is essential for prey capture but not attention to prey in the praying mantis Sphodromantis lineola

This study shows binocular vision is crucial for prey capture but not for attention to prey in praying mantises using 3D cinema stimuli.

Temporal consistency of judgement biases in bumblebees

This study assesses whether judgment biases in bumblebees reflect stable traits or transient states by testing individual consistency across repeated sessions.

Testing bottom-up cuing effects on target detection and discrimination in Bumblebees

This study tests bottom-up cuing effects on target detection and discrimination in bumblebees using adapted primate paradigms, finding no effect of prior cues.

Motivational trade-offs as evidence for sentience in bees: a critique

This paper critiques a study claiming bees exhibit motivational trade-offs, finding methodological limitations and no support for the conclusion that bees can trade-off heat against reward.

Acute stress modulates early visual perception and decision-making speed in bees without compromising accuracy

This study shows acute stress in bees changes visual perception and decision-making speed without affecting accuracy.

A Computational Model of Stereoscopic Prey Capture inPraying Mantises

The paper develops a computational model of stereoscopic prey capture in praying mantises that reproduces key neurophysiological and behavioral features.

Apparent Motion Perception in the Praying Mantis: Psychophysics and Modelling

This study investigates how Dmax scales with element size in praying mantises, finding a power-law relationship without a lower bound, contrasting human findings, and presents two models to explain the results.

Contrast Thresholds Reveal Different Visual Masking Functions In Humans And Praying Mantises

This study compares how visual noise affects contrast thresholds in humans and praying mantises, finding differences in masking effectiveness across spatial frequencies.

Invisible noise obscures visible signal in insect motion detection

The paper shows that invisible noise can impair motion detection in insects but not mammals due to differences in early visual processing.
