Ferry, Alissa; Nespor, Marina; Mehler, Jacques – Developmental Psychology, 2020
To learn a language infants must learn to link arbitrary sounds to their meaning. While words are the clearest example of this link, they are not the only component of language; morphological regularities (e.g., the plural -s suffix in English) carry meaning as well. Comprehensive theories of language acquisition must account for how infants build…

Rakison, David H.; Yermolayeva, Yevdokiya – Journal of Cognition and Development, 2011
A longstanding and fundamental debate in developmental science is whether knowledge is acquired through domain-specific or domain-general mechanisms. To date, there exists no tool to determine whether experimental data support one theoretical approach or the other. In this article, we argue that the U- and N-shaped curves found in a number of…

Libertus, Melissa E.; Pruitt, Laura B.; Woldorff, Marty G.; Brannon, Elizabeth M. – Journal of Cognitive Neuroscience, 2009
Behavioral studies show that infants are capable of discriminating the number of objects or events in their environment, while also suggesting that number discrimination in infancy may be ratio-dependent. However, due to limitations of the dependent measures used with infant behavioral studies, the evidence for ratio dependence falls short of the…

Brannon, Elizabeth M.; Suanda, Sumarga; Libertus, Klaus – Developmental Science, 2007
Time perception is important for many aspects of human behavior, and a large literature documents that adults represent intervals and that their ability to discriminate temporal intervals is ratio dependent. Here we replicate a recent study by vanMarle and Wynn (2006 ) that used the visual habituation paradigm and demonstrated that temporal…

Swoboda, Philip J.; And Others – Child Development, 1976
This study investigated vowel discrimination in 8-week-old infants. Using a nonnutritive, high-amplitude sucking measure in a habituation-dishabituation paradigm. (Author/SB)

Maye, Jessica; Werker, Janet F.; Gerken, LouAnn – Cognition, 2002
Familiarized 6- and 8-month-olds with speech sounds from a phonetic continuum, exhibiting a bimodal or unimodal frequency distribution. Found that only infants in the bimodal condition discriminated tokens from the endpoints of the continuum. Results demonstrate that infants are sensitive to the statistical distribution of speech sounds in the…

Miller, Dolores J.; And Others – International Journal of Behavioral Development, 1980
Longitudinal data gathered on 24 children at 51 months of age and at earlier ages suggest that children currently characterized as faster habituators, in terms of first fixation data, may be somewhat advanced cognitively compared to slower habituators. (Author/DB)

Mareschal, Denis; Powell, Daisy; Volein, Agnes – Journal of Experimental Child Psychology, 2003
Examined 7- and 9-month-olds' ability to categorize cats and dogs as separate from one another. Found that both groups formed a cat category that included novel cats but excluded a dog and an eagle, and formed a dog category that included novel dogs and a novel cat but excluded an eagle. Results mirrored those of 3- to 4-month-olds with visual…

Wisdom, Sara S.; Friedlander, Bernard Z. – 1971
Sixteen 9-18 month normal/superior infants "played" in their home cribs with a two-channel operant "toy" which allowed free choice between alternate audio feedbacks. With more than 300,000 seconds of listening time in the response record, 12 babies successfully discriminated gross differences in auditory complexity, while 10 discriminated fine…

Casasola, Marianella; Cohen, Leslie B.; Chiarello, Elizabeth – Child Development, 2003
Two experiments examined six-month-olds' ability to form an abstract containment category. Results indicated that, after habituation to object pairs in a containment relation, infants looked reliably longer at an example of an unfamiliar versus familiar containment relation, indicating that they could form a categorical representation of…

Casasola, Marianella – Child Development, 2005
Two experiments explored how infants learn to form an abstract categorical representation of support (i.e., on) when habituated to few (i.e., 2) or many (i.e., 6) examples of the relation. When habituated to 2 pairs of objects in a support relation, 14-month-olds, but not 10-month-olds, formed the abstract spatial category (i.e., generalized the…

Eimas, Peter D.; Quinn, Paul C. – Journal of Experimental Child Psychology, 1998
Examined representation of pictorial exemplars of humans by 3- and 4-month olds. Results demonstrated an asymmetry regarding the exclusivity of categorical representations formed for humans and non-human animals. Categorical representations for humans included exemplar information, whereas categorical representation for non-human animals was based…

Rochat, Philippe; Striano, Tricia – Child Development, 2002
Investigated early determinants of infants' self--other discrimination when presented with a live image of themselves or another person that was either contingent or contingent with delay. Found that infants 4 months and older perceived and acted differently when facing the image of themselves compared to that of another; 9-month-olds showed more…

Meltzoff, Andrew N. – Developmental Psychology, 1995
Two experiments examined whether 40 infants would reenact what an adult did or intended to do: (1) infants observed an adult unsuccessfully attempt to complete 4 target acts; and (2) children observed a mechanical device tracing the adults' actions. Infants could infer adults' intentions and imitate target acts, suggesting that children can…

Pauen, Sabina – Child Development, 2002
Two studies examined whether infants' category discrimination in an object-examination task was based solely on an ad hoc analysis of perceptual similarities among the experimental stimuli. Findings indicated that 10- to 11-month- olds' responses varied systematically only with the presence of a category change, but not with the degree of…
