Statistical learning (SL), the ability to detect and extract regularities from inputs, has been considered as an early-maturing and domain-general mechanism that is critical for typical language development. However, recent evidence in neurotypical adults and children have found that individuals can vary in their SL abilities across linguistic and…

Two studies examined factors that predicted children's tendencies to match objects versus relations across scenes when no instruction was given. Study 1 examined a) age and b) nationality as a proxy for cultural differences in experiences with relations. The results showed that Chinese and U.S. children across ages all showed an initial bias to…

Multisensory attention skills provide a crucial foundation for early cognitive, social, and language development, yet there are no fine-grained, individual difference measures of these skills appropriate for preverbal children. The Multisensory Attention Assessment Protocol (MAAP) fills this need. In a single video-based protocol requiring no…

Purpose: This study examined whether children and adults with developmental language disorder (DLD) could use distributional information in an artificial language to learn about grammatical category membership similarly to their typically developing (TD) peers and whether developmental differences existed within and between DLD and TD groups.…

Incivility involves rude, discourteous, and disrespectful attitudes and behaviours. The present study examined how various temperament traits were related to beliefs of classroom incivility among adolescents. The sample comprised of 222 adolescents (120 boys) between the ages of 12 and 17 (M[superscript age] = 14.07, SD = 1.54) who were recruited…

The current study examined the relations between individual differences in attention to emotion faces and temperamental negative affect across the first 2 years of life. Infant studies have noted a normative pattern of preferential attention to salient cues, particularly angry faces. A parallel literature suggests that elevated attention bias to…

Four- to 10-year-olds and adults (N = 265) responded to eight scenarios presented on an eye tracker. Each trial involved a character who encounters a perpetrator who had previously enacted positive (P), negative (N), or both types of actions toward him or her in varying sequences (NN, PP, PN, and NP). Participants predicted the character's…

Hannula and Lehtinen (2001, 2005) defined spontaneous focusing on numerosity (SFON) as the tendency to notice the relatively abstract attribute of number despite the presence of other attributes. According to nativists, an innate concept of one to three directs young children's attention to these "intuitive numbers" in everyday situations--even…

Two experiments examined age differences in children's dual-task performance. Findings indicated that when capacity for single-task performance was controlled, age differences between second and fifth graders did not exist in performance of dual-tasks of equal priority. When tasks had different priorities, only fifth graders could differentially…

Less is known about the effects of normal aging on speech output than other motor actions, because studies of communication integrity have focused on voice production and linguistic parameters rather than speech production characteristics. Studies investigating speech production in older adults have reported increased syllable duration (Slawinski,…

Examined whether early individual differences in look duration were related to general mechanisms of the infant nervous system combining attention and emotion. Found significant positive correlations between attention measures and duration of facial expressions of pain/distress after vaccinations at 3, 5, and 11 months. Concluded that individual…

Problem solving and related observation behaviors were assessed using 108 subjects in three age groups (4 years, 8 years, and college undergraduates). Interference from uninformative stimuli affected all ages, but decreased at older ages. Only the adults exhibited selective, relevant observation behaviors. (Author/DB)

Examined claim that associations between emotional responses to maternal separation and cognitive performance would change with cognitive development over the first year. Emphasized the measurement of separation and reunion distress. Found that emotional responses and cognitive performance may be linked by individual differences in self-regulation…

Three studies explored age changes and individual differences in preschoolers' sustained attention in different contexts. Found that changes occurred earlier for play and television viewing than for reaction time tasks. Results suggest that children have stable tendencies to sustain attention but that attention varies with task demands and…

Evaluates relevance of existing instructional research on computer-assisted instruction, programed instruction, instructional video, and instructional television to the study of interactive video; describes several assumptions about interactive video use which require validation and study; and proposes a propositional framework to guide the…
