Information-seeking in mice (Mus musculus) during visual discrimination: study using a distractor elimination...

Area of Science:

• Animal behavior
• Cognitive science
• Neuroscience

Background:

• Information-seeking behavior is crucial for animal metacognition and monitoring knowledge states.
• Previous research has primarily focused on primates, neglecting rodents, the most common experimental animals.
• Understanding metacognitive control in rodents is essential for broader insights into animal cognition.

Purpose of the Study:

• To investigate information-seeking behavior in mice during visual discrimination tasks.
• To determine the factors influencing information-seeking in rodents.
• To assess whether information-seeking in mice reflects metacognitive processes.

Main Methods:

• Mice were trained on visual discrimination tasks with varying difficulty levels (luminance and orientation).
• An option to seek information (eliminate distractors) was incorporated into the tasks.
• Generalization tests were conducted to evaluate the mice's reliance on environmental cues.

Main Results:

• Mice increased information-seeking behavior with higher task difficulty.
• Generalization tests indicated that mice utilized environmental cues to employ the information-seeking option.
• The findings suggest a potential influence of external factors on information-seeking behavior.

Conclusions:

• Information-seeking behavior in mice during these tasks may not exclusively represent metacognitive control.
• Environmental cues play a significant role in how mice utilize information-seeking options.
• Further studies are required to elucidate the underlying mechanisms and alternative explanations for this behavior in rodents.
