Emerging adulthood is proposed as a new conception of development for the period from the late teens through the twenties, with a focus on ages 18-25. A theoretical background is presented. Then evidence is provided to support the idea that emerging adulthood is a distinct period demographically, subjectively, and in terms of identity explorations. How emerging adulthood differs from adolescenc...

Adults recognize that if event A predicts event B, intervening on A might generate B. Research suggests that young children have difficulty making this inference unless the events are initiated by goal-directed actions [1]. The current study tested the domain-generality and development of this phenomenon. Replicating previous work, when the events involved a physical outcome, toddlers (mean: 24...

Many of the phenomena underlying shape recognition can be derived from the greater sensitivity to nonaccidental properties of an image (e.g., whether a contour is straight or curved), which are invariant to orientation in depth, than to the metric properties of an image (e.g., a contour's degree of curvature), which can vary with orientation. What enables this sensitivity? One explanation is th...

STUDY OBJECTIVE The purpose of the study was to assess the attention level of middle-school students by providing a group of students with the opportunity for an additional one hour of sleep in the morning by delaying school starting time by one hour, as compared to another group received no additional sleep. METHOD For the first week of the study, the school starting time was delayed 1 h for...

This study confirmed the hypothesis that pregnant teenagers in the 1990s are more likely to have a mother who had a teenage pregnancy than non-pregnant teenagers. It also found that the daughters of teenage mothers are more likely to continue their own pregnancies.

Following the proposal that consonants are more involved than vowels in coding the lexicon (Nespor, Peña & Mehler, 2003), an early lexical consonant bias was found from age 1;2 in French but an equal sensitivity to consonants and vowels from 1;0 to 2;0 in English. As different tasks were used in French and English, we sought to clarify this ambiguity by using an interactive word-learning study ...

PURPOSE Increased Internet accessibility has been accompanied by an increased awareness of pathological Internet use (PIU). The aim of the study was to investigate a potential increase of PIU among European adolescents. METHODS Comparable data from two large cross-sectional multicentre, school-based studies conducted in 2009/2010 and 2011/2012 in five European countries (Estonia, Germany, Ita...

The detrimental effects of prolonged pacifier use on the developing oral structures are often the primary focus of dental professionals; however, non-nutritive sucking with a pacifier has other consequences that include not only harmful effect but positive influences as well. This article will address some of the issues for consideration regarding the use of pacifiers and provide information fo...

In this study, Limburgian and Dutch 2.5- to 4-year-olds and adults took part in a word learning experiment. Following the procedure employed by Quam and Swingley (2010) and Singh et al. (2014), participants learned two novel word-object mappings. After training, word recognition was tested in correct pronunciation (CP) trials and mispronunciation (MP) trials featuring a pitch change. Since Limb...
