Question 1

_____ refers to the manner in which loudness varies as a piece of music progresses.

Accepted Answer

Dynamics refer to the variations in loudness or intensity in a piece of music. It's how composers and performers express changes in mood and emotion through louder or softer passages.

Question 2

Two versions of the same melody containing the same intervals but starting at different notes are called:

Accepted Answer

Transpositions refer to the process of moving the entire set of notes in a melody up or down in pitch by the same interval, resulting in the melody starting on a different note but maintaining the same intervals between notes.

Question 3

_____ refers to the temporal patterning of events in a musical composition, encompassing tempo, beat, and meter.

Accepted Answer

Rhythm is the aspect of music that deals with the timing of sounds, including tempo (the speed of the music), beat (the basic unit of time in music), and meter (the pattern of beats).

Question 4

According to the pitch helix, notes that are exactly one octave apart:

Accepted Answer

Notes that are exactly one octave apart share the same tone chroma, which refers to their perceived similarity in sound despite the difference in pitch. This is why they are often considered equivalent in many musical contexts.

Question 5

Wanda is practicing the happy birthday song on a piano. Some of the notes are too high for her, so she starts singing in a lower note. This scenario MOST likely illustrates:

Accepted Answer

Transpositions involve changing the key of a piece of music to make it easier to play or sing, which is what Wanda is doing by singing in a lower note.

Question 6

In Western music, each octave consists of 13 notes separated by _____ proportionally equivalent intervals called semitones.

Accepted Answer

An octave in Western music is divided into 12 semitones, which are the smallest intervals used in the Western musical scale. These semitones are proportionally equivalent, allowing for the chromatic scale that spans one octave.

Question 7

The French physician Pierre Paul Broca described two patients with damage to a region in the:

Accepted Answer

Broca identified damage in the left inferior frontal cortex of patients who had significant difficulties with speech production, leading to the identification of this area as Broca's area, crucial for speech production.

Question 8

Carl Wernicke, the German neurologist, described patients with damage to a region in the:

Accepted Answer

Carl Wernicke described a condition known as Wernicke's aphasia, characterized by deficits in speech comprehension, associated with damage to the left superior temporal cortex.

Question 9

According to musical notes and the range of pitches of musical instruments, A4 has a fundamental frequency of 220 Hz, and A5 has a fundamental frequency of _____ Hz.

Accepted Answer

The frequency of A5 is 440 Hz, which is double the frequency of A4 (220 Hz) in music, following the pattern that each octave higher doubles the frequency.

Question 10

The term _____ refers to the quality exhibited by a combination of two or more notes from a scale that sounds unpleasant, or "off."

Accepted Answer

Dissonance refers to a combination of notes that sounds harsh or unpleasant to the ear, often creating a sense of tension in music.

Question 11

In the context of speech-related neural signals, the ventral pathway is involved in speech _____ and the dorsal pathway is involved in speech _____.

Accepted Answer

The ventral pathway is involved in speech perception, helping us understand spoken language, while the dorsal pathway is involved in speech production, aiding in the generation of speech sounds.

Question 12

According to the text, the phoneme transition probability for the sequence /kt/ at the start of a word would be _____ percent.

Accepted Answer

The phoneme transition probability for the sequence /kt/ at the start of a word is zero percent because in English, words do not start with the /kt/ sound combination, making such a transition impossible at the beginning of a word.

Question 13

_____ refers to the chances that any particular sequence of phonemes occurs at the start of a word, in the middle of a word, at the end of a word, or across the boundary between two words.

Accepted Answer

Phoneme transition probability refers to the likelihood of a specific sequence of phonemes occurring in certain positions within words or at the boundary between words. This concept is crucial in understanding how listeners can predict upcoming sounds based on the phonemes they have already heard, aiding in speech perception and processing.

Question 14

Betsy was listening to the radio. She did not realize that a phoneme in the announcer's speech had been replaced by a coughing sound. The fact that she seemed to perceive the missing speech sounds illustrates:

Accepted Answer

Phonemic restoration is a phenomenon where the brain automatically fills in missing phonemes during speech perception, allowing individuals to understand words even if part of the sound is missing or obscured, as in the case with the coughing sound in the scenario described.

Question 15

_____ refers to an impairment in speech production or comprehension, or both, caused by damage to speech centers in the brain.

Accepted Answer

Aphasia is a condition characterized by either partial or total loss of the ability to communicate verbally or using written words. It is caused by damage to the brain areas responsible for speech and language.

Question 16

Julia met with a road accident. After the accident, she was able to understand what other people spoke. However, she was able to produce only a few words of speech. The accident has MOST likely destroyed her _____ frontal cortex.

Accepted Answer

The left inferior frontal cortex is associated with Broca's area, which is crucial for speech production. Damage to this area can result in Broca's aphasia, where comprehension remains intact but the ability to produce speech is severely impaired.

Question 17

In the perception of speech sounds, when auditory and visual stimuli conflict, the auditory system tends to compromise on a perception that shares features with both the seen and the heard stimuli. This phenomenon is called:

Accepted Answer

The McGurk effect demonstrates how visual information (lip movements) can alter the perception of auditory speech sounds, leading to a compromised perception that incorporates features from both the seen and heard stimuli.

Question 18

In the perception of speech sounds, the McGurk effect occurs when _____ and _____ conflict.

Accepted Answer

The McGurk effect occurs when auditory and visual stimuli conflict, demonstrating how our perceptions can be influenced by information from different sensory modalities.

Question 19

Plantinga and Trainor (2005) conducted a study in which six-month-old infants were exposed to a melody repeatedly over seven days. On the eighth day, the infants either heard the familiar melody transposed to a different starting note or heard an unfamiliar melody. According to this study, when given a choice, young infants looked longer toward the speaker playing:

Accepted Answer

The answer of Plantinga and Trainor (2005) conducted a study...

Question 20

In Western music, notes that are exactly one octave apart:

Accepted Answer

Notes that are exactly one octave apart have similar sound qualities because they share a fundamental frequency ratio of 2:1, which makes them harmonically compatible and perceived as similar in character.
