Suanda, Sumarga H.; Namy, Laura L. – Infancy, 2013
Infants' early communicative repertoires include both words and symbolic gestures. The current study examined the extent to which infants organize words and gestures in a single unified lexicon. As a window into lexical organization, eighteen-month-olds' ("N" = 32) avoidance of word-gesture overlap was examined and compared with…

Kovack-Lesh, Kristine A.; Oakes, Lisa M.; McMurray, Bob – Infancy, 2012
We examined how infants' categorization is jointly influenced by previous experience and how much they shift their gaze back and forth between stimuli. Extending previous findings reported by K. A. Kovack-Lesh, J. S. Horst, and L. M. Oakes (2008), we found that 4-month-old infants' (N = 122) learning of the exclusive category of "cats" was related…

Butler, Joseph; Floccia, Caroline; Goslin, Jeremy; Panneton, Robin – Infancy, 2011
This study investigates infants' discrimination abilities for familiar and unfamiliar regional English accents. Using a variation of the head-turn preference procedure, 5-month-old infants demonstrated that they were able to distinguish between their own South-West English accent and an unfamiliar Welsh English accent. However, this distinction…

Valiante, A. Grace; Barr, Ronald G.; Zelazo, Philip R.; Brant, Rollin; Young, Simon N. – Infancy, 2013
Newborn infants preferentially orient to familiar over unfamiliar speech sounds. They are also better at remembering unfamiliar speech sounds for short periods of time if learning and retention occur after a feed than before. It is unknown whether short-term memory for speech is enhanced when the sound is familiar (versus unfamiliar) and, if so,…

Hay, Jessica F.; Saffran, Jenny R. – Infancy, 2012
Linguistic stress and sequential statistical cues to word boundaries interact during speech segmentation in infancy. However, little is known about how the different acoustic components of stress constrain statistical learning. The current studies were designed to investigate whether intensity and duration each function independently as cues to…

Moll, Henrike; Carpenter, Malinda; Tomasello, Michael – Infancy, 2011
Previous research has found that young children recognize an adult as being acquainted with an object most readily when the child and adult have previously engaged socially with that object together. In the current study, we tested the hypothesis that such social engagement is so powerful that it can sometimes lead children to overestimate what…

Simpson, Elizabeth A.; Varga, Krisztina; Frick, Janet E.; Fragaszy, Dorothy – Infancy, 2011
Perceptual narrowing--a phenomenon in which perception is broad from birth, but narrows as a function of experience--has previously been tested with primate faces. In the first 6 months of life, infants can discriminate among individual human and monkey faces. Though the ability to discriminate monkey faces is lost after about 9 months, infants…

Peterson, Mary A. – Infancy, 2011
Bhatt and Quinn (2011) review the substantial evidence that learning constrains perceptual organization in infants. With those findings as a foundation, they discuss five kinds of experiences that engender learning in infants and propose that attention and unitization mediate infant learning. Bhatt and Quinn's article is informative--the ideas…

Gredeback, Gustaf; Eriksson, Malin; Schmitow, Clara; Laeng, Bruno; Stenberg, Gunilla – Infancy, 2012
Fourteen-month-old infants were presented with static images of happy, neutral, and fearful emotional facial expressions in an eye-tracking paradigm. The emotions were expressed by the infant's own parents as well as a male and female stranger (parents of another participating infant). Rather than measuring the duration of gaze in particular areas…

Stenberg, Gunilla – Infancy, 2012
Three laboratory experiments on social referencing examined whether infants' tendencies to look at and use positive information from the experimenter could be interpreted from a perspective of novelty or expertise. In Study 1, novelty was manipulated. Forty-eight 12-month-old infants participated. In a between-subject design, a more novel or a…

Moore, David S.; Johnson, Scott P. – Infancy, 2011
Mental rotation involves transforming a mental image of an object so as to accurately predict how the object would look if it were rotated in space. This study examined mental rotation in male and female 3-month-olds, using the stimuli and paradigm developed by Moore and Johnson (2008). Infants were habituated to a video of a three-dimensional…

Kucker, Sarah C.; Samuelson, Larissa K. – Infancy, 2012
Recent research demonstrated that although 24-month-old infants do well on the initial pairing of a novel word and novel object in fast-mapping tasks, they are unable to retain the mapping after a 5 min delay. The current study examines the role of familiarity with the objects and words on infants' ability to bridge between the initial fast…

Fennell, Christopher T. – Infancy, 2012
Infants greatly refine their ability to discriminate language sounds by 12 months, yet 14-month-olds appear to confuse similar-sounding novel words. Two explanations could account for this phenomenon: infants initially have incomplete phoneme representations, suggesting developmental discontinuity; or word-learning demands interfere with use of…

Luo, Yuyan – Infancy, 2010
Some actions of agents are ambiguous in terms of goal-directedness to young infants. If given reasons why an agent performed these ambiguous actions, would infants then be able to perceive the actions as goal-directed? Prior results show that infants younger than 12 months can not encode the relationship between a human agent's looking behavior…

Harel, Hagar; Gordon, Ilanit; Geva, Ronny; Feldman, Ruth – Infancy, 2011
Although research has demonstrated poor visual skills in premature infants, few studies assessed infants' gaze behaviors across several domains of functioning in a single study. Thirty premature and 30 full-term 3-month-old infants were tested in three social and nonsocial tasks of increasing complexity and their gaze behavior was micro-coded. In…
