Objectives: The present study investigated the influence of juror gender and infant victim disability on jurors' reactions to infanticide cases. Methods: Participants (men and women undergraduates) read a summary of a mock trial involving alleged father-perpetrated infanticide. The infant was described as severely mentally disabled or as not…

Recognition memory impairment after selective hippocampal lesions in monkeys is more profound when measured with visual paired-comparison (VPC) than with delayed nonmatching-to-sample (DNMS). To clarify this issue, we assessed the impact of stimuli similarity and encoding duration on the VPC performance in monkeys with hippocampal lesions and…

The purpose of this study is to examine the perspectives of Filipino immigrant mothers regarding the roles and focus of their interactions with their infants and toddlers. Qualitative procedures were used to analyse transcripts from structured, open-ended interviews with 24 mothers of 10- to 36-month-old children. Statements of mothers were…

Previous studies have shown that 7.5-month-olds can track and encode words in fluent speech, but they fail to equate instances of a word that contrast in talker gender, vocal affect, and fundamental frequency. By 10.5 months, they succeed at generalizing across such variability, marking a clear transition period during which infants' word…

The authors discuss three steps to helping babies with transitions: observe, ask, and respond (OAR). They advise teachers about how to ask a family questions about their baby and how to give the family suggestions to alleviate the baby's stress, without offending family members. This column includes a list of recommended resources. (Contains 7…

According to the Census Bureau, the number of Americans over age 65 is expected to double, reaching 72 million by 2030. So in addition to the 54.6 million Americans already challenged with disabilities, there will be a significant new population of people aging into disabilities as the Baby Boom generation takes the stage as senior citizens. When…

Research on initial conceptual knowledge and research on early statistical learning mechanisms have been, for the most part, two separate enterprises. We report a study with 11-month-old infants investigating whether they are sensitive to sampling conditions and whether they can integrate intentional information in a statistical inference task.…

From birth, human infants are able to perceive a wide range of intersensory relationships. The current experiment examined whether infants between 6 months and 24 months old perceive the intermodal relationship between aggressive and nonaggressive canine vocalizations (i.e., barks) and appropriate canine facial expressions. Infants simultaneously…

Purpose: To compare response patterns to video visual reinforcement audiometry (VVRA) and conventional visual reinforcement audiometry (CVRA) in infants 7-16 months of age. Method: Fourteen normal-hearing infants aged 7-16 months (8 male, 6 female) participated. A repeated measures design was used. Each infant was tested with VVRA and CVRA over 2…

English-learning 7.5-month-olds are heavily biased to perceive stressed syllables as word onsets. By 11 months, however, infants begin segmenting non-initially stressed words from speech. Using the same artificial language methodology as Johnson and Jusczyk (2001), we explored the possibility that the emergence of this ability is linked to a…

From an early age, so much emphasis goes into teaching children the fundamentals of color theory, in particular the primary colors of red, yellow, and blue. Toys, building blocks, furniture, and so many other items used in a preschool environment are manufactured in these three colors. Yet, recent research has uncovered that babies as young as…

Purpose: The present study explored articulator movement variability during voicing contrast acquisition. The purpose was to examine whether oral articulator movement trajectories associated with the production of voiced/voiceless bilabial phonemes in children became less variable over time. Method: Jaw, lower lip, and upper lip movements were…

To explore early lexical development, the authors examined infants' sensitivity to changes in spoken syllables and objects given different temporal relations between syllable-object pairings. In Experiment 1, they habituated 2-month-olds to 1 syllable, /tah/ or /gah/, paired with an object in "synchronous" (utterances coincident with object…

Teacher research served as both the content and frame of analysis for this study. Parallel teacher research projects took place over the course of a year as preservice teachers engaged in their first experience with teacher research as part of an infant-toddler development course and the first author (their instructor) engaged in teacher research…

We analyzed two nationally representative, longitudinal data sets of U.S. children to identify risk factors for persistent mathematics difficulties (PMD). Results indicated that children from low socioeconomic households are at elevated risk of PMD at 48 and 60 months of age, as are children with cognitive delays, identified developmental delays…
