Behavioral, Cognitive, And Genetic Factors Underlying Socio-Communicative Development In Bonobos, Sara Skiba
Behavioral, Cognitive, And Genetic Factors Underlying Socio-Communicative Development In Bonobos, Sara Skiba
Psychology Dissertations
Although it is clear that behavioral, cognitive, and genetic factors all contribute to socio-communicative development in humans, it remains a significant challenge to disentangle the contribution of each to the emergence of socio-communicative abilities. Recent research has demonstrated that single nucleotide polymorphisms (SNPs) are linked to social behavior and cognition in humans and nonhuman mammals. Bonobos, one of the species most closely related to humans, exhibit complex socio-communicative behavior and cognition, and exhibit similar connections between genetic factors and individual-level social behavior to those observed in humans. This study is the first comprehensive assessment of the behavioral, cognitive, and genetic …
Relationships Between Cerebello-Cortical Functional Connectivity And Executive Functioning Across Childhood And Adolescence, Sarah V. Clark
Relationships Between Cerebello-Cortical Functional Connectivity And Executive Functioning Across Childhood And Adolescence, Sarah V. Clark
Psychology Dissertations
The cerebellum is a modulator of both motor and cognitive functions, helping to make these behaviors both coordinated and efficient. It is structurally and functionally connected to the prefrontal cortex (PFC) through multisynaptic, closed-loop circuits. Neuroimaging studies have established that the posterior lobules of the cerebellum are active during executive function (EF) tasks and are functionally connected to cortical regions of EF-associated networks such as the fronto-parietal network (FPN) and cingulo-opercular network (CON). Despite much evidence that the developmental timecourses of EF and cerebello-cortical connectivity are similar, and early damage to the cerebellum can cause numerous cognitive deficits, relationships between …
Development Of Visual-Verbal Integration In Working Memory During Childhood And Its Relation To Language And Reading, M. Katrina Smith
Development Of Visual-Verbal Integration In Working Memory During Childhood And Its Relation To Language And Reading, M. Katrina Smith
Psychology Dissertations
Research has demonstrated working memory improves during childhood and supports vocabulary, grammar, and reading development (Adams & Gathercole, 1995, 1996; Bowey, 1996; Gathercole & Baddeley, 1989, 1990). Prior to the addition of the episodic buffer in Baddeley’s model of working memory (2000a), auditory and visual aspects of working memory were often treated separately without evaluating contributions from the ability to integrate the two forms of information. The present study was designed to investigate the development of visual-verbal integration in working memory and its role in language and reading development. Tests of receptive vocabulary, receptive grammar, and decoding ability were administered …
