Visuospatial selective attention in chickens.

Area of Science:

• Cognitive Neuroscience
• Animal Behavior
• Comparative Psychology

Background:

• Voluntary attention is crucial for intelligent behavior, enabling selective information processing for decision-making.
• While extensively studied in primates, the capacity for selective attention in nonprimate species remains largely unquantified.

Purpose of the Study:

• To quantify selective visual spatial attention in chickens using established primate protocols.
• To investigate if chickens can dynamically shift attention based on spatial cues and to understand the impact of distracters.

Main Methods:

• Chickens were trained to localize targets amidst distracters, using spatial cues to predict target location.
• Performance was assessed via accuracy (d') and reaction times, with signal detection analysis employing an 'indecision' model.

Main Results:

• Spatial cueing significantly improved target localization accuracy and decreased reaction times in a space-specific manner.
• Cueing reduced the performance impairment caused by distracters and increased choice certainty in target localization.
• Error-aversion certainty remained constant, indicating attention mechanisms parallel those in primates.

Conclusions:

• Chickens demonstrate rapid and dynamic spatial attention shifts, mirroring primate attentional control principles.
• These findings suggest conserved attentional mechanisms across evolution.
• Chickens are proposed as a valuable model for studying the neural basis of selective attention due to their visual acuity and trainability.
