Mesotocin Influences Pinyon Jay Prosociality, J. F. Duque, W. Leichner, H. Ahmann, Jeffrey R. Stevens

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

Many species exhibit prosocial behavior , in which one individual’s actions benefit another individual, often without an immediate benefit to itself. The neuropeptide oxytocin is an important hormonal mechanism influencing prosociality in mammals, but it is unclear whether the avian homologue mesotocin plays a similar functional role in birds. Here, we experimentally tested prosociality in pinyon jays (Gymnorhinus cyanocephalus), a highly social corvid species that spontaneously shares food with others. First, we measured prosocial preferences in a prosocial choice task with two different pay-off distributions: Prosocial trials delivered food to both the subject and either an empty cage …

Spanish: Existen escasos estudios sobre la forma de evaluar el proceso sensorial en adultos; una de estas formas es el uso de perfil sensorial desarrollado por Brown y Dunn en el año 2002, aplicable tanto para la población infantil como adulta de habla inglesa. Hasta el momento no existe una evaluación de procesamiento sensorial del adulto validada en castellano. En base a estos antecedentes, el principal objetivo de este estudio es validar la construcción interna de una escala de procesamiento sensorial en el adulto a través del Cuestionario del Proceso Sensorial del Adulto (CPSA) con una población de habla hispana, …

Aging, Neuromuscular Decline, And The Change In Physiological And Behavioral Complexity Of Upper-Limb Movement Dynamics, S. Morrison, K. M. Newell

Rehabilitation Sciences Faculty Publications

Aging is characterized by a general decline in physiological and behavioral function that has been widely interpreted within the context of the loss of complexity hypothesis. In this paper, we examine the relation between aging, neuromuscular function and physiological-behavioral complexity in the arm-hand effector system, specifically with reference to physiological tremor and isometric force production. Experimental findings reveal that the adaptive behavioral consequences of the aging-related functional decline in neurophysiological processes are less pronounced in simple motor tasks which provides support for the proposition that the motor output is influenced by both extrinsic (e.g., task related) and intrinsic (e.g., coordination, …
