✓Well SupportedThere is an innate, genetically influenced predisposition to learn vocalizations.◐Partially SupportedLearning a new language as an adult is easier if one has already learned multiple languages early in development.◐Partially SupportedLearned behaviors like speaking or playing the piano utilize forebrain circuits, distinct from brainstem circuits.◐Partially SupportedGenes involved in neuroplasticity are specialized in speech circuits to facilitate more complex learning compared to motor skills.Partially Supported

Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

Engaging in activities like dancing can help improve cognitive function and thinking abilities by strengthening the connection between movement and cognition pathways.

✓Well SupportedEngaging in activities like dancing helps keep the brain fresh and cognitively intact.

◐Partially SupportedGenes involved in calcium buffering and neuroprotection are upregulated in speech circuits because larynx muscles require high neuronal activity and generate toxicity.

◐Partially SupportedNeanderthals likely had spoken language, with speech circuit gene sequences similar to modern humans.

◐Partially SupportedBehavioral therapy focused on sensory motor integration and controlling auditory feedback can help adults overcome stuttering.

✕Not SupportedThere is no strong evidence for a separate language module in the brain; instead, speech production and auditory perception pathways contain complex algorithms for spoken language.

◐Partially SupportedPracticing speech, oratory, or singing maintains cognitive circuits by engaging facial motor pathways.

◐Partially SupportedThe brain may need to discard information to accommodate new learning due to limited memory capacity.

◐Partially SupportedVocal learning birds share behavioral and neural similarities with humans, including critical learning periods and vocal deterioration if deaf.

◐Partially SupportedHumans, parrots, and dolphins use learned sounds for semantic communication.

◐Partially SupportedThe entire brain undergoes a critical period of development in early childhood, making skill acquisition easier than in adulthood.

◐Partially SupportedNeurogenic stuttering in humans can result from damage to the basal ganglia, particularly the speech area, at a young age.

◐Partially SupportedDogs understand several hundred human speech words, and great apes understand several thousand, but cannot produce speech.

◐Partially SupportedConsistent physical movement, such as dancing, walking, or running, is necessary for maintaining cognitive function into old age.
