Mobile Technology Use And School Readiness In Low-Income Preschoolers, Trina M. Harmon
Mobile Technology Use And School Readiness In Low-Income Preschoolers, Trina M. Harmon
Masters Theses
Once a luxury, mobile devices are now utilized by most members of society, including those in even the poorest communities. Unfortunately, little research has examined the effects of mobile media use in young children, and even less on young children from low-SES communities. Past research on television, and preliminary research on mobile technology, suggests that mobile media may affect school readiness, and that the direction and strength of this relation could depend on the content and context of the use. The current study examined the relation between mobile media use and a composite school readiness measure that included preliteracy, emergent …
Representation Of Reward And Risk In The Brain’S Motor System: Studies In Adolescents And Adults, Xingjie Chen
Representation Of Reward And Risk In The Brain’S Motor System: Studies In Adolescents And Adults, Xingjie Chen
Doctoral Dissertations
In the neuroscience of economic decision making, the brain’s motor system has been ascribed a role in implementing choice actions. However, recent work has revealed canonical motor signals much in advance of choice action, possibly indicating their role in evaluation of decision options. In the current dissertation, we applied multimodal neuroimaging combining EEG and fMRI and used a novel paradigm that temporally separated the evaluation phase from the action phase of a decision-making process to investigate the mechanisms through which the motor control system contributes to decision making. Additionally, we further examined the developmental changes during the two phases of …
Slow Wave Sleep In Naps Supports Episodic Memories In Early Childhood, Sanna Lokhandwala
Slow Wave Sleep In Naps Supports Episodic Memories In Early Childhood, Sanna Lokhandwala
Masters Theses
Naps have been shown to benefit declarative memories in early childhood. This benefit has been associated with sleep spindles during the nap. However, whether young children’s naps and their accompanying physiology benefit other forms of declarative learning is unknown. Using a novel storybook task, we found performance was better following a nap compared to performance following an equivalent interval spent awake. Moreover, performance was better the following day if a nap followed learning. Further, change in post-nap performance was positively associated to the amount of time spent in slow wave sleep. This suggests that slow wave sleep in naps may …
Children's Understanding Of Compositionality Of Complex Numerals, Jihyun Hwang
Children's Understanding Of Compositionality Of Complex Numerals, Jihyun Hwang
Masters Theses
Counting is the first formal exposure for children to learn numerals, which are constructed with a set of syntactic rules. Young children undergo many stages of rote-memorization of the sequence and eventually count through 100. What core knowledge is necessary to expand their number knowledge to higher numbers? The compositionality of numerals is a key to understanding the natural number system as in learning languages. Higher numbers (e.g., two hundred five) are constructed with the lexical items such as earlier numbers (e.g., one to nine) and multipliers. If children develop their understanding of the compositionality of numerals, they might comprehend …
Differential Harsh Parenting And Sibling Differences In Conduct Problems: The Role Of Effortful Control, Yelim Hong
Differential Harsh Parenting And Sibling Differences In Conduct Problems: The Role Of Effortful Control, Yelim Hong
Masters Theses
Differential parenting has been shown to be an important correlate and possible cause of positive and negative adjustment of sibling children. However, it is not known whether sibling differences in temperament affect this link between differential harsh parenting and sibling differences in adjustment outcomes. The current study addressed this gap in knowledge. The sample included 92 monozygotic (MZ, 63% female) twin pairs and 137 dizygotic same-sex (DZ, 52% female) twin pairs who had complete temperament survey data collected near the third annual wave in the longitudinal study. Children were 6.09 years old (SD = .69) years old at wave 1. …

The profound effects of child maltreatment on brain functioning have been documented. Yet, little is known about whether distinct maltreatment experiences are differentially related to underlying neural processes of risky decision making: valuation and control. Using conditional growth curve modeling, we compared a cumulative approach versus a dimensional approach (relative effects of abuse and neglect) to examine the link between child maltreatment and brain development. The sample included 167 adolescents (13?14 years at Time 1, 53 % male), assessed annually four times. Risk processing was assessed by blood-oxygen-level-dependent responses (BOLD) during a lottery choice task, and cognitive control by BOLD …
Positive Youth Development: Parental Warmth, Values, And Prosocial Behavior In 11 Cultural Groups, Concetta Pastorelli, Antonio Zuffianò, Jennifer E. Lansford, Eriona Thartori, Marc H. Bornstein, Lei Chang, Kirby Deater-Deckard, Laura Di Gunta, Kenneth A. Dodge, Sevtap Gurdal

The current cross-cultural study aimed to extend research on parenting and children's prosocial behavior by examining relations among parental warmth, values related to family obligations (i.e., children's support to and respect for their parents, siblings, and extended family), and prosocial behavior during the transition to adolescence (from ages 9 to 12). Mothers, fathers, and their children (N = 1107 families) from 8 countries including 11 cultural groups (Colombia; Rome and Naples, Italy; Jordan; Kenya; the Philippines; Sweden; Thailand; and African Americans, European Americans, and Latin Americans in the United States) provided data over 3 years in 3 waves (M-age of …
