Inhibitory control in teleost fish: a methodological and conceptual review

Area of Science:

• Comparative Psychology
• Cognitive Ecology
• Neuroscience
• Animal Behavior

Background:

• Inhibitory control (IC) is crucial for regulating behavior by overriding impulses and distractions.
• While extensively studied in mammals and birds, IC research in other vertebrates, like fish, is emerging.
• Teleost fish offer a valuable model for understanding the evolution and diversity of cognitive control.

Purpose of the Study:

• To review current literature on inhibitory control in teleost fish.
• To analyze methodological approaches and conceptual findings in fish IC research.
• To highlight the potential of fish as models for comparative cognition and neuroscientific studies.

Main Methods:

• Systematic review of existing research on inhibitory control in teleost fish.
• Analysis of common experimental paradigms used to assess IC in fish.
• Examination of comparative (interspecific) and individual (intraspecific) variability in fish IC.

Main Results:

• Established behavioral tasks for studying fish IC are identified, with pros and cons discussed.
• Comparative studies show similarities in IC across fish species, relating to ecology and brain size.
• Intraspecific variations in fish IC are linked to sex, personality, genetics, age, and plasticity.

Conclusions:

• Teleost fish demonstrate substantial inhibitory control capabilities, mirroring findings in other vertebrate groups.
• Fish IC research contributes significantly to understanding cognitive evolution and behavioral regulation.
• Further research in fish holds promise for comparative psychology, cognitive ecology, neuroscience, and even psychiatric applications.
