midterm 3 Flashcards
habituation and dishabituation
habituation: when looking time declines after training on one stimulus; baby increases looking time at novel stimulus (then decay); studies discrimination
dishabituation: if looking time increases to new stimulus (after habituation to old stimulus); indicates that the infant can discriminate the new stimulus from the old one
conditioned head-turn
infants turn head toward novel stimulus; in training, is rewarded for head turn; used for studying discrimination (same/different judgments); method adds conditioning to encourage head turning; head turning eventually happens in advance of stimulus due to reinforcement
preferential looking
infants look longer at preferred stimulus; studies preference
enculturation
the acquisition of implicit or explicit knowledge about the norms, symbols, and rules of the society within which one lives
infant-directed singing and infant-directed speech
infant-directed singing: softer, heightened pitch, slower tempo, added nonsense syllables, interactive, different timbre; purposes include creating bonds between parent and child, helping to modulate infant’s mood, teaching words and other things
infant-directed speech: “motherese”; heightened speech used when talking to infants; higher pitch, exaggerated contour (rising to get attention, falling to put to sleep), slower, nonsense syllables, highly repetitive
isochronous vs non-isochronous meter
isochronous meter: regularly spaced beats
non-isochronous meter: irregularly spaced beats; rare in Western music, common in some other cultures
predisposition
innate ability or preference
prenatal hearing
hearing starts 25 weeks after conception; sounds elicit heartrate changes; the fetus hears mother’s rhythmic breathing, walking, heartbeat; can hear loudness attenuated by about 30 dB; the amniotic fluid is a low-pass filter (muffles the higher frequencies); fetuses in the last trimester can detect speech contour, timing of phonemes, changes in loudness, overall pitch level, and some musical patterns, and they prefer mother’s voice to other voices
Lauren Trainor and Sandra Trehub
Trainor: studied ID speech, scale structure, and babies’ perceptions of consonance and dissonance
Trehub: studied how children perceive sound (i.e., ID speech and lullabies)
equal vs unequal step scale
equal step scale: whole tone scale; more difficult to process
unequal step scale: major and novel (11-step chromatic) scales
arousal vs valence
arousal: what makes music seem high in energy/activity
valence: (primarily mode) is what makes music seem positive vs. negative
basic emotions
evolved to help us survive; exist in all cultures (universal); have distinct facial expressions; happiness, sadness, anger, fear in music (disgust, surprise in studies outside music)
circumplex model of emotion
Russell; music can convey four quadrants; (1) - valence, + arousal (angry, upset); (2) + valence, + arousal (excited, elated); (3) + valence, - arousal (relaxed, serene); (4) - valence, - arousal (depressed, lethargic)
felt emotion
“emotional induction”; the emotion that a piece of music makes us feel; the “emotivist” position that music arouses emotions in listeners (often via expectation denial or fulfilment); general/cultural and personal/specific associations; Leonard Meyer and David Huron
perceived emotion
“emotional recognition”; the emotion that we perceive in a piece; the “cognitivist” position that music represents or refers to emotions in some way, either by imitating them or through some conventional means; Peter Kivy and Deryck Cooke
