Purpose: Some speech recognition data suggest that children rely less on voice pitch and harmonicity to support auditory scene analysis than adults. Two experiments evaluated development of speech-in-speech recognition using voiced speech and whispered speech, which lacks the harmonic structure of voiced speech. Method: Listeners were 5- to…

This study is a case study that investigates the perceptions of preschool children about the causes, consequences, and solutions to environmental problems. A total of 41 children participated in the study. The data were obtained by using the draw and explain the technique, which included 3 different drawings and telling the children about the…

In an exploratory, intensive case study, we investigated the well-being of young children (0-4 years) with a time-sampling design. The total sample included 940 individual observations for 30 children during four consecutive weeks. Data collection involved external coding of videotaped episodes and caregiver- and parent-reported measures.…

We explore how children and adults actively experiment within the physical world to achieve different epistemic goals. In our experiment, one hundred one 4- to 10-year-old children and 24 adults either passively observed or used a touchscreen interface to actively interact with objects in a dynamic physical microworld with the goal of inferring…

People rely on reputational information communicated via gossip when deciding about with whom to cooperate, whom to believe, and whom to trust. In two studies, we investigated whether 5- and 7-year-old children trust in gossip when determining a course of action. In Study 1, 5- and 7-year-old German-speaking peer dyads (N = 64 dyads, 32 female…

Age-related developments in sleep during the preschool years are normative and consequential. Yet, very few studies have examined the antecedents of individual differences in such developments, and most have used parental reports of child sleep. This study aimed to investigate the roles of mutual responsiveness in mother-child interactions and…

Using a sample of healthy youth (n = 466, 10 to 18 yr), we report the predictive utility of vertical jump power (VJ Power, W) for predicting bone strength. We measured VJ Power using mechanography and an indicator of bone strength, i.e., height-adjusted total bone mineral content less head (TBLH BMC, g), using DXA. Growth curve models were used to…

This study coordinates moral value development in adolescence, parenting style, and gender with issues of stability and specificity. The primary research question asked whether parenting styles of mothers and fathers influence the development of adolescent moral values, and secondary research questions asked whether adolescent moral values were…

Research has identified the benefits and challenges of creating multigenerational classrooms for the purpose of intergenerational learning in higher education. However, much less has been written about the systems of support needed at the organizational level to promote intergenerational learning within lifelong learning initiatives as a key…

Previous research has reported the long-lasting effects of children's early adjustment to formal schooling on their later academic lives. However, little has been studied on whether father and teacher communication styles perceived by children during their early school years are comparable. This study explored the relationship between father and…

Despite the importance of self-control for well-being and adjustment, its development from early childhood to early adolescence has been relatively understudied. We addressed the development of mother-reported self-control in what is likely the largest and longest longitudinal twin study of the topic to this day (N = 1889 individual children with…

Experiential learning and reflection activities are often used to enhance students' understanding of and attitudes toward aging; however, deep reflection is difficult to achieve, and research shows students demonstrate varying abilities to reflect. This study examined the extent to which students in a third-year gerontology course were able to…

Over the last two decades, twenty-two states have moved away from traditional defined benefit (DB) pension systems and toward pension plan structures like the defined contribution (DC) plans now prevalent in the private sector. Others are considering such a reform as it is seen as a means of limiting future pension funding risk. It is important to…

Visualizations are commonly used in educational materials, however not all visualizations are equally effective at promoting learning. Prior research has supported the idea that both perceptually rich and bland visualizations are beneficial for learning and generalization. We investigated whether the perceptual richness of a life cycle diagram…

Children's storybooks often contain fantasy elements, from dragons and wizards to anthropomorphic animals that wear clothes, talk, and behave like humans. These elements can impact children's learning from storybooks both positively and negatively, perhaps due in part to their ability to capture children's interest and attention. Prior research…
