Visuospatial Reasoning In Toddlers: A Correlational Study Of Door Task Performance, Iris Louella Price
Visuospatial Reasoning In Toddlers: A Correlational Study Of Door Task Performance, Iris Louella Price
Open Access Dissertations
Previous research using violation-of-expectation paradigms suggests that very young infants have a good understanding of unobserved physical events. Yet toddlers appear to lack this knowledge when confronted with the door task, a visuospatial reasoning task which parallels ones used in the habituation/looking time studies. Many studies have been conducted in an effort to determine why toddlers perform poorly on the door task yet the answer remains unclear. The current study used a correlational approach to investigate door task performance from both psychological (executive function), and neuroscience (prefrontal cortex) perspectives. Children between the ages of 2 ½ - 3 years were …
Landscape Ecology Of Large Fires In Southwestern Forests, Usa, Sandra L Haire
Landscape Ecology Of Large Fires In Southwestern Forests, Usa, Sandra L Haire
Doctoral Dissertations 1896 - February 2014
The recent increase in large fires in southwestern forests has prompted concern regarding their ecological consequences. Recognizing the importance of spatial patterns in influencing successional processes, I asked: (1) How do large fires change plant communities?; (2) What are the implications of these changes for ponderosa pine forests?; and (3) What is the relationship of fire severity to gradients of climate, fuels, and topography? To address the first two questions, I studied succession in the woody plant community at two sites that burned in high-severity fire: La Mesa fire in northern New Mexico (1977) and Saddle Mountain in northern Arizona …
