요약Early word learning is characterized by mapping labels for objects to the so-called "basic" level of description, such as dog. This basic-level bias presents a challenge for the eventual acquisition of words that differ in semantic specificity, such as the narrower subordinate-level (e.g., dalmatian) and the broader superordinate-level (e.g., animal) nouns. Previous literature has typically treated the acquisition of these kinds of nouns as disparate problems. Subordinate nouns are often characterized in terms of the perceptual distinctiveness of their referents and thus their meanings are thought to be acquired via the convergence of physical cues from the world. By contrast, superordinate nouns are thought to be initially difficult due to the unavailability of the corresponding concepts but trivially acquired via induction upon conceptual maturity in later childhood. Of course, such views have not gone unchallenged - a parallel line of work has reported strong contributions from the language input in overcoming the basic-level bias in acquisition, raising questions about the scope of the perceptual and conceptual challenges truly posed by learning words beyond the basic level.Building on this linguistic perspective, this dissertation develops a pragmatically-motivated framework that unifies the seemingly disparate challenges to the acquisition of subordinate and superordinate nouns. Starting from the premise that hierarchical noun meanings form a scale on the basis of their semantic specificity, this position predicts that the acquisition of these words is guided by the accessibility and relevance of specific linguistic-semantic alternatives that pragmatically constrain the generalization of word meanings. A series of studies tests the consequences of this pragmatic position for the acquisition and interpretation of subordinate and superordinate nouns. Beginning with subordinates, Study 1 (Chapter 2) shows that semantic alternatives modulate subordinate-level conjectures in a word learning study with adults. Similarly, Study 2 (Chapter 3) demonstrates that children also generate such contrastive inferences in word learning, and are additionally able to integrate inferences about speaker knowledge. Turning to superordinates, Study 3 (Chapter 4) shows that the distribution of superordinate nouns in the input both reflects, and is discoverable from, their semantic-pragmatic properties. Lastly, Study 4 (Chapter 5) shows that children are sensitive to the pragmatic conditions that license when superordinate-level meanings are talked about. In conclusion, this dissertation demonstrates that the acquisition and use of words at different levels of specificity is in large part characterized by the task of reasoning about a speaker's intent in their choice of a specific word among relevant alternatives. These findings further our understanding of the pragmatic forces that shape the acquisition of hierarchical noun meanings, and the development of adult-like pragmatic competence that governs the unspoken rules of their usage.

■520    ▼aEarly  word  learning  is  characterized  by  mapping  labels  for  objects  to  the  so-called  "basic"  level  of  description,  such  as  dog.  This  basic-level  bias  presents  a  challenge  for  the  eventual  acquisition  of  words  that  differ  in  semantic  specificity,  such  as  the  narrower  subordinate-level  (e.g.,  dalmatian)  and  the  broader  superordinate-level  (e.g.,  animal)  nouns.  Previous  literature  has  typically  treated  the  acquisition  of  these  kinds  of  nouns  as  disparate  problems.  Subordinate  nouns  are  often  characterized  in  terms  of  the  perceptual  distinctiveness  of  their  referents  and  thus  their  meanings  are  thought  to  be  acquired  via  the  convergence  of  physical  cues  from  the  world.  By  contrast,  superordinate  nouns  are  thought  to  be  initially  difficult  due  to  the  unavailability  of  the  corresponding  concepts  but  trivially  acquired  via  induction  upon  conceptual  maturity  in  later  childhood.  Of  course,  such  views  have  not  gone  unchallenged  -  a  parallel  line  of  work  has  reported  strong  contributions  from  the  language  input  in  overcoming  the  basic-level  bias  in  acquisition,  raising  questions  about  the  scope  of  the  perceptual  and  conceptual  challenges  truly  posed  by  learning  words  beyond  the  basic  level.Building  on  this  linguistic  perspective,  this  dissertation  develops  a  pragmatically-motivated  framework  that  unifies  the  seemingly  disparate  challenges  to  the  acquisition  of  subordinate  and  superordinate  nouns.  Starting  from  the  premise  that  hierarchical  noun  meanings  form  a  scale  on  the  basis  of  their  semantic  specificity,  this  position  predicts  that  the  acquisition  of  these  words  is  guided  by  the  accessibility  and  relevance  of  specific  linguistic-semantic  alternatives  that  pragmatically  constrain  the  generalization  of  word  meanings.  A  series  of  studies  tests  the  consequences  of  this  pragmatic  position  for  the  acquisition  and  interpretation  of  subordinate  and  superordinate  nouns.  Beginning  with  subordinates,  Study  1  (Chapter  2)  shows  that  semantic  alternatives  modulate  subordinate-level  conjectures  in  a  word  learning  study  with  adults.  Similarly,  Study  2  (Chapter  3)  demonstrates  that  children  also  generate  such  contrastive  inferences  in  word  learning,  and  are  additionally  able  to  integrate  inferences  about  speaker  knowledge.  Turning  to  superordinates,  Study  3  (Chapter  4)  shows  that  the  distribution  of  superordinate  nouns  in  the  input  both  reflects,  and  is  discoverable  from,  their  semantic-pragmatic  properties.  Lastly,  Study  4  (Chapter  5)  shows  that  children  are  sensitive  to  the  pragmatic  conditions  that  license  when  superordinate-level  meanings  are  talked  about.  In  conclusion,  this  dissertation  demonstrates  that  the  acquisition  and  use  of  words  at  different  levels  of  specificity  is  in  large  part  characterized  by  the  task  of  reasoning  about  a  speaker's  intent  in  their  choice  of  a  specific  word  among  relevant  alternatives.  These  findings  further  our  understanding  of  the  pragmatic  forces  that  shape  the  acquisition  of  hierarchical  noun  meanings,  and  the  development  of  adult-like  pragmatic  competence  that  governs  the  unspoken  rules  of  their  usage.
