Developmental Stress And The Effects On Physiological And Cognitive-Behavioural Traits In European Starlings, Tara M. Farrell Nov 2015

Developmental Stress And The Effects On Physiological And Cognitive-Behavioural Traits In European Starlings, Tara M. Farrell

Electronic Thesis and Dissertation Repository

Birdsong is a complex, learned vocalization that is a phenotypic expression of male quality. The developmental stress hypothesis describes how the cost to possessing a high quality song is paid in early development. Stressful early-life experiences have adverse effects on the development of the neural circuitry that regulates song learning and production, which results in a male advertising with a low quality song in adulthood. The purpose of this thesis was to test the developmental stress hypothesis in several respects in European starlings (Sturnus vulgaris). My objectives were to assess the long-term effects of developmental stress on (1) …


The Effect Of A Combined Multiple-Modality Exercise Intervention On Sensorimotor Function In Community Dwelling Older Adults, With A Subjective Cognitive Complaint: The M4 Study (Multi-Modal; Mind Motor), Sam Titheridge Oct 2015

The Effect Of A Combined Multiple-Modality Exercise Intervention On Sensorimotor Function In Community Dwelling Older Adults, With A Subjective Cognitive Complaint: The M4 Study (Multi-Modal; Mind Motor), Sam Titheridge

Aging is associated with the increased onset of diseases such as cognitive impairment, and ultimately dementia. Participants, 55+ years, with a self-reported cognitive complaint completed a 6-month exercise intervention. They were randomized to either a multiple modality exercise program (M2), consisting of aerobic, stretching and balancing exercises or a multiple modality plus mind motor program (M4), whereby a square stepping exercise was incorporated. Participants were assessed for reaction time (RT), movement time (MT) and % errors at baseline and at 6-months using an eye tracking 1000 system. Participants performed prosaccades and antisaccades (AS). AS RT was significantly quicker from baseline …


The Effect Of A Multiple Modality Mind-Motor Exercise Intervention On Single And Dual-Task Gait, Balance, And Executive Function, In Community Dwelling Older Adults With A Subjective Cognitive Complaint: A Randomized Controlled Trial., John P. Bocti Aug 2015

The Effect Of A Multiple Modality Mind-Motor Exercise Intervention On Single And Dual-Task Gait, Balance, And Executive Function, In Community Dwelling Older Adults With A Subjective Cognitive Complaint: A Randomized Controlled Trial., John P. Bocti

Cognitive decline disorders are becoming increasingly prevalent, with older adults at increased risk. Combined exercise has been recently explored as an intervention to help to prevent the decline, however cognitive activation in combination with physical activity has yet to be explored. Therefore, the purpose of the study is to determine the effects of multiple modality exercise programs in combination with a mind-motor task and their effects on mobility and cognitive variables. A total of (n=89) older adults (55+ yrs), with subjective cognitive complaints participated in a multiple modality exercise class, three days a week over six months, with the intervention …
