 esonators of acoustic musical instruments \n\n	 \n\n	Abstract:\n\n		Timbre pla
 ys a crucial role in sound source recognition. Musical instrument sounds c
 arry timbral information about two mechanical properties: the excitation s
 ets into vibration the resonator\, which filters sound components. Excitat
 ion–resonator interactions in the physical world are restrictive: Strings 
 can be bowed and struck but seldom blown. We used Modalys to combine three
  excitations (bowing\, blowing\, striking) with three resonators (string\,
  air column\, plate)\, simulating nine interactions. These interactions ar
 e either typical (e.g.\, bowed string) or atypical (e.g.\, blown plate). E
 xperiment 1 involved dissimilarity ratings of stimulus pairs. Experiment 2
  entailed explicit categorization of excitations and resonators of the sti
 muli. Experiment 3 comprised three learning tasks training participants on
  the stimuli’s excitation\, resonator\, or interaction categories. Trainin
 g involved trial and error with corrective feedback\, followed by an expli
 cit categorization task based on trained categories. Multidimensional scal
 ing revealed a three-dimensional timbre space (Experiment 1). Dimension 1 
 showed a clear boundary between struck and continuous excitations. Dimensi
 on 2 isolated plates and Dimension 3 further separated strings and air col
 umns. Listeners accurately categorized excitations and resonators of typic
 al interactions (Experiments 2 & 3). They assimilated atypical interaction
 s to typical ones (Experiment 2). This confusion was reduced after trainin
 g was involved (Experiment 3). Therefore\, categorical boundaries of excit
 ations and resonators were already formed implicitly and not made explicit
  until training took place. These studies reveal that excitation and reson
 ator properties can be processed independently. Furthermore\, they highlig
 ht the role of timbre in an essential process of human behaviour: identify
 ing the source of a sound. \n	\n\n	\n		\n			\n				\n					\n						\n							\n								\n									\n										\n											\n												 \n											\n										\n									\n								\n							\n						\n					\n				\n

 r the supervision of Stephen McAdams at the Music Perception and Cognition
  Lab. Her research combines her backgrounds in music cognition\, experimen
 tal psychology\, and timbre perception. She is particularly interested in 
 how individuals categorize novel sounds and how they become incorporated i
 nto their mental models. \n		\n	\n\n	\n		 \n\n
