Flexibility In Parent-Child Interactions: The Application Of Dynamic Systems Methodology To Dyadic Processes In Children With Behaviour Problems, Vivien Lee Dec 2011

Flexibility In Parent-Child Interactions: The Application Of Dynamic Systems Methodology To Dyadic Processes In Children With Behaviour Problems, Vivien Lee

Electronic Thesis and Dissertation Repository

Dynamic systems theory (DST) can provide a comprehensive account for how parent-child interactions evolve over time to produce stable patterns of interacting and can result in seemingly divergent trajectories. Recent methodological advances using state space grids (SSGs) have provided a graphical means to examine real-time dyadic processes, as well as measures of dyadic flexibility, or the ability to adapt emotional and behavioural responding in response to contextual demands. Higher levels of dyadic flexibility have been associated with improvements in child behaviour problems after treatment (Granic et al., 2007), while its converse, rigidity, has been associated with increases in behaviour …


The Power Of Dialogue: Understanding Developmental Origins And Processes Underlying Mother-Child Conversations About Past Emotional Events, Celia Hsiao Sep 2011

The Power Of Dialogue: Understanding Developmental Origins And Processes Underlying Mother-Child Conversations About Past Emotional Events, Celia Hsiao

Electronic Thesis and Dissertation Repository

Mother-child emotion dialogues represent an integral medium through which children’s autobiography develops. This study sought to understand the developmental origins and processes underlying this co-construction process by examining the inter-relations between: mother-infant attachment relationships, maternal attachment representations, maternal sensitivity during interactions in infancy, maternal affective mindset during toddlerhood, and mother-child emotion dialogues.

Our findings are consistent with past research on the links between the three organized categories of mother-infant attachment relationships and later mother-child emotion dialogues. Children in disorganized attachment relationships displayed a lack of consistent and coherent strategy during emotion communication. Our results emphasize the important role of maternal …


An Observational Assessment Of Peer Group Contributions To Adolescent Identity Development, Tara M. Dumas Jun 2011

An Observational Assessment Of Peer Group Contributions To Adolescent Identity Development, Tara M. Dumas

Electronic Thesis and Dissertation Repository

The purpose of this study was to demonstrate that interaction-based peer groups play an important role in adolescents’ identity development. Peer group members’ current identity development and peer group interaction processes were examined as predictors of teens’ later identity exploration and commitment. Participants (n = 1070; 522 girls; Mage = 15.45 years) reported on their identity development and a subset of participants took part in an interactive group decision task within peer triads (n = 258; 86 triads). Task-related interactions were coded for support (openness to opinions) or discouragement (teasing of opinions and controlling behaviours) of …


Dissociable And Dynamic Components Of Cognitive Control: A Developmental Electrophysiological Investigation, Matthew Waxer Apr 2011

Dissociable And Dynamic Components Of Cognitive Control: A Developmental Electrophysiological Investigation, Matthew Waxer

Electronic Thesis and Dissertation Repository

One standard task used to investigate the development of cognitive control is the Dimensional Change Card Sort (DCCS). Performance and patterns of brain activity associated with the DCCS show continued age-related advances into early adolescence. According to many theoretical accounts, the DCCS places demands on a single underlying executive control process. Three experiments examined the possibility that the DCCS places demands on multiple control processes that follow distinct developmental trajectories. In Experiment 1, rule switching and conflict processing made orthogonal contributions to DCCS performance. Rule switching was associated with a cue-locked late frontal negativity (LFN) event-related potential (ERP) and conflict …
