This study investigates crossmodal fear generalization, testing whether conditioned fear spreads between different sensory modalities. Participants in the unimodal group were presented with visual stimuli--images of a sparrow (CS+) and a laptop (CS-)--while the crossmodal group received auditory stimuli--sparrow calls (CS+) and keyboard typing…

We investigate when infants exhibit knowledge of the familiar size of well-known objects and whether this knowledge is affected by stimulus format, that is, whether the stimuli are presented as real objects or matched pictures. Infants (130 7- and 12-month-olds) saw everyday objects such as sippy cups and pacifiers in their familiar size and novel…

Many differences exist between preschool and kindergarten classrooms, including the type and time spent on fine motor activities. Children at risk for developmental delays and learning challenges as they transition to kindergarten often require direct support during preschool to learn new skills needed for kindergarten. This study expanded the…

Recombinative generalization is the production of responses in the presence of novel combinations of known components. For example, after learning "red triangle" and "blue square," recombinative generalization is observed when a child can tact "red square" and "blue triangle." Recombinative generalization…

Category learning is fundamental to cognition, but little is known about how it proceeds in real-world environments when learners do not have instructions to search for category-relevant information, do not make overt category decisions, and do not experience direct feedback. Prior research demonstrates that listeners can acquire task-irrelevant…

Purpose: Children and early adolescents seem to have an advantage over adults in acquiring nonnative speech sounds, supported by evidence showing that earlier age of acquisition strongly predicts second language attainment. Although many factors influence children's ultimate success in language learning, it is unknown whether children rely on…

Children on the autism spectrum often experience difficulty generalizing social skills across environments and contexts, which can make developing friendships challenging in early childhood. This means that, in addition to initial social skills instruction, children with autism may need specialized supports to promote the generalization of newly…

This dissertation investigates the impact of cross-modal binding on word reading skills among English Language Learners (ELLs). Using Baddeley's updated working memory model, which includes the Episodic Buffer, this study examines how the ability to bind visual and phonological information in memory influences the reading development of ELL…

This study explores how feature salience and feature centrality influence inductive generalization in 4- and 5-year-old children and adults. Recent reports indicate that enhancing the salience of a feature--specifically, a creature's head--by making it move shifts children's inductions so that they ignore labels and make inferences that are…

The 4 experiments reported here used the preferential looking and habituation paradigms to examine whether 5-month-olds possess a perceptual template for snakes, sharks, and rodents. It was predicted that if infants possess such a template, then they would attend preferentially to schematic images of these nonhuman animal stimuli relative to…

We can incidentally learn regularities in a visual scene, and this kind of learning facilitates subsequent processing of similar scenes. One example of incidental learning is referred to as "contextual cueing," a phenomenon in which repetitive exposure to a particular spatial configuration facilitates visual search performance in the…

Young children who cannot use their natural speech to communicate their daily wants, needs, thoughts, and opinions often rely on augmentative and alternative communication (AAC) strategies that frequently use graphic symbols to assemble messages. Early intervention strategies typically focus on visual scene displays (VSDs) to place target messages…

This study aimed to determine whether attentional prioritization of stimuli associated with reward transfers across conceptual knowledge independently of physical features. Participants successively performed two color-word Stroop tasks. In the learning phase, neutral words were associated with high, low, or no monetary reward. In the…

Recently it has been shown that rewarded variability can be used to adapt visuomotor behavior. However, its relevance seems limited because adaptation to binary rewards has been demonstrated only when the same movement is repeated throughout the experiment. We therefore investigated whether the adaptation is action-specific and whether the amount…

Instruction in academic core content provides students with moderate to severe disabilities a full educational opportunity that promotes current and future options in the community and can complement acquisition of daily living skills. However, high school teachers face many challenges in balancing instructional priorities given the mission to…
