Test on Origins of Human Language

Question 1: The "yo-he-ho" theory, which suggests language emerged from sounds used to coordinate physical activity, fully explains the origins of the specific sounds early humans produced.

A. Ano

B. Ne

Explanation: While the "yo-he-ho" theory places the development of human language in a social context and involves the use of sounds for coordinating physical activities, the study materials explicitly state that it "does not, however, reveal the origins of the sounds produced."

Question 2: Which of the following observations support the Musical Source theory regarding the origin of human language, according to the provided study materials?

A. Human infants develop intonation and the ability to create melody before other aspects of language.

B. The ability to produce language is primarily linked to the spontaneous utterance of sounds in physical effort, known as the 'yo-he-ho' theory.

C. Newborn infants can recognize the intonation of their mother’s voice and prefer the intonation of their mother’s language.

D. Early humans solely relied on imitations of natural sounds like 'cuckoo' and 'bow-wow' to form their first words.

Explanation: The study materials state that 'intonation, and hence the ability to create melody, develops in the human infant before other aspects of language' and 'newborn infants have found that they can recognize the intonation of their mother’s voice and orient to that voice more than any other. They also show a preference for the intonation of their mother’s language'. These points directly support the Musical Source theory. Option 1 refers to the 'yo-he-ho' theory, and option 3 refers to the 'bow-wow' theory, both of which are distinct from the Musical Source theory.

Question 3: Are the upright, even, and smaller characteristics of human teeth, along with the intricate muscle interlacing and flexibility of human lips, considered helpful for producing various speech sounds?

A. Ano

B. Ne

Explanation: Human teeth are described as being upright, even in height, and smaller, which are very helpful in making sounds such as f or v. Similarly, human lips have much more intricate muscle interlacing, and their resulting flexibility certainly helps in making sounds like p, b and m.

Question 4: Which of the following characteristics accurately describe the human mouth and tongue in relation to speech production, according to the provided materials?

A. The human mouth is large compared to other primates, facilitating sound resonance.

B. Humans possess a shorter, thicker, and more muscular tongue capable of shaping diverse sounds.

C. The human mouth can be opened and closed rapidly, contributing to sound delivery.

D. Humans are unique among primates in their ability to close off the nasal airway to increase mouth air pressure.

Explanation: The study materials state that the human mouth is 'relatively small compared to other primates' (making option 0 incorrect) and 'can be opened and closed rapidly' (making option 2 correct). It also mentions that humans have a 'shorter, thicker and more muscular tongue that can be used to shape a wide variety of sounds inside the oral cavity' (making option 1 correct). Furthermore, it notes that 'unlike other primates, humans can close off the airway through the nose to create more air pressure in the mouth' (making option 3 correct).

Question 5: Is the coordination of human infant gestures and vocalizations primarily observed when a child forms complete sentences while performing a complex series of hand movements?

A. Ano

B. Ne

Explanation: The coordination of gestures and vocalizations is observed in the use of an index finger pointing gesture and a vocalization such as baba when a familiar figure is present. The study materials do not describe this coordination as involving complete sentences or a complex series of hand movements.
