Mothers Do Not Drive The Development Of Adult Homesign Systems: Evidence From Comprehension, Emily Carrigan
Mothers Do Not Drive The Development Of Adult Homesign Systems: Evidence From Comprehension, Emily Carrigan
Master's Theses
Studying the communication systems that arise in spontaneously occurring cases of degraded linguistic input can help clarify human predispositions for language. Some deaf individuals born into hearing families, who do not receive conventional linguistic input, develop gestures, called “homesign,” to communicate. We examined homesign systems used by four deaf Nicaraguan adults (ages 15-27), and evaluated whether homesigners’ hearing mothers are potential sources for these systems. Study One measured mothers’ comprehension of descriptions of events (e.g., “A man taps a woman”) produced in homesign and spoken Spanish. Mothers comprehended spoken Spanish descriptions (produced by one of their hearing children) better than …
The Multi-Scale Dynamics Of Executive Function, Jason Anastas
The Multi-Scale Dynamics Of Executive Function, Jason Anastas
Master's Theses
Cognitive control is a central issue in developmental psychology. Traditional theories of psychology solve this problem by positing a top-down central executive, which coordinates cognitive resources in pursuit of goals. We propose an alternative explanation: cognitive control arises from physical interactions across many different timescales within the system. College and preschool aged participants were asked to complete a simple executive function task, card sorting. We found that multi-scale physical interactions differed depending on experimental constraints, and that executive function in these cases was driven primarily by flexibility in multi-scale interactions, rather than the dominance of one scale. This suggests that, …
The Influence Of Adult- Versus Child-Directed Television Programs On Distractibility In Preschoolers, Kathryn Joyce O'Toole
The Influence Of Adult- Versus Child-Directed Television Programs On Distractibility In Preschoolers, Kathryn Joyce O'Toole
Master's Theses
Research in the field on children's attention to television has suggested that discerning between two different types of programming is crucial for understanding how children attend to TV. Child-directed television consists of programs designed with the purpose that children are the intended viewers. In contrast, adult-directed television is not designed for children; these programs are directed toward an older audience. The current study investigated how children divided their attention between cognitive tasks and a distractor. The distractor was either an adult-directed TV program, a child-directed TV program, or there was no distractor. The results revealed that the both distractors reduced …
