Not All Numbers Were Created Equal: Evidence The Number One Is Unique, Jenna L. Croteau Nov 2023

Not All Numbers Were Created Equal: Evidence The Number One Is Unique, Jenna L. Croteau

Masters Theses

Universally across modern cultures children acquire the meaning of the words one, two, and three in order. While much research has focused on how children acquire this knowledge and what this knowledge represents, the question of why children learn numbers in order has been comparatively neglected. To address this question, a non-verbal anticipatory looking task was implemented. In this task, 35 14- to 23-month-old infants were assessed on their ability to form implicit category structures for the numbers one, two, and three. We hypothesized that children would be able to form the implicit category structure for the number one …


Two Of The Same? Infants' Conceptual Representation Of Faces Based Upon Gender, Race, And Kind Information, Charisse Pickron Jul 2018

Two Of The Same? Infants' Conceptual Representation Of Faces Based Upon Gender, Race, And Kind Information, Charisse Pickron

Doctoral Dissertations

Infants’ perceptual abilities allow them to distinguish faces of different races and genders from an early age (for a review, see Pascalis et al., 2011). However, it is still unknown when infants begin using these perceptual differences to represent faces in a conceptual, kind-based manner. The current dissertation examined this issue by testing whether 12- and 24-month-old infants represent faces of different races and genders as distinct ‘kinds’ or instead as variations of a single broader category (e.g., ‘human face’). The current dissertation included two experiments each with a different type of violation-of-expectation individuation paradigm. Experiment 1 used a passive …


The Influence Of Early Media Exposure On Children’S Development And Learning, Katherine Hanson Jul 2017

The Influence Of Early Media Exposure On Children’S Development And Learning, Katherine Hanson

Doctoral Dissertations

A number of studies suggest that the amount of early screen media exposure is related to negative developmental outcomes, namely poorer executive functioning and language skills (Anderson & Pempek, 2005). Television’s constant presence in the home could lead to potentially serious consequences for infants and toddlers. However, hypotheses attributing long-term negative outcomes to the direct effects of television on children are limited. There are no definitive mechanisms to explain how these effects are instantiated within children over time. Furthermore, the indirect influences of television on children remain entirely unexplored. Television’s impact can have a potentially greater indirect effect on young …


Infants' Reasoning About Agents' Identity: The Case Of Sociomoral Kinds, Hernando Taborda Nov 2016

Infants' Reasoning About Agents' Identity: The Case Of Sociomoral Kinds, Hernando Taborda

Doctoral Dissertations

Recent studies in development psychology suggest that early on infants are able to distinguish characters who display a cooperative behavior from characters who display an antisocial behavior. The current research builds on these findings and aims at determining the extent to which infants possess the sociomoral distinction of “good” and “mean” agents. In particular, we propose that infants represent sociomoral behaviors through kind-based categories. This hypothesis was tested in the current research across 5 different experiments by investigating how infants represent the identity of agents in sociomoral situations. Experiment 1 used a looking-time paradigm to demonstrate 11-month-old infants’ bias to …


The Influence Of Television Exposure On Infants' Toy Play, Katherine G. Hanson Jan 2010

The Influence Of Television Exposure On Infants' Toy Play, Katherine G. Hanson

Masters Theses 1911 - February 2014

The association between television exposure and infants’ toy play was examined. Specifically, differences in the amount of program content and coviewing in the home were expected to predict different patterns of play when children were away from television. This thesis also sought to extend Pempek’s (2007) findings indicating that the more parents coviewed certain baby videos (i.e., Sesame Beginnings) in the home with their children, the more likely these parents actively engaged with their children in the laboratory. Consequently, the current thesis examined whether or not this active engagement resulted in something meaningful for children’s play behaviors. Parents of infants …
