Performance consequences have been long established when humans multitask. This research concerns the impact of distraction on the attentional shifts during a task that underlies many cognitive processes and everyday tasks, searching for a target item among non-target items (e.g., scanning the road for potential collisions). There is evidence that increasing the mental workload by introducing additional tasks influences our ability to search our environment or interferes with processing...
Show morePerformance consequences have been long established when humans multitask. This research concerns the impact of distraction on the attentional shifts during a task that underlies many cognitive processes and everyday tasks, searching for a target item among non-target items (e.g., scanning the road for potential collisions). There is evidence that increasing the mental workload by introducing additional tasks influences our ability to search our environment or interferes with processing fixated information. In the current studies, I aimed to evaluate the changes in gaze behaviors during visual search to evaluate how multitasking impairs our attentional processes. Participants completed a visual search task (search for a target T among distractor L's) while wearing a heads-up display (Google Glass) which displays an unrelated word during the dual task condition, while the control condition required participants to complete the search task without distraction. The changes in oculomotor behavior were observed in four experiments: (1) evaluating general oculomotor behavior during distraction, (2) masking the display onset of the secondary information during an eye movement to reduce the possibility of distraction from the word appearing, (3) removing any occlusion of stimuli from the heads-up display by having no visual overlap of the two tasks, and (4) evaluating whether oculomotor behaviors were similar to previous results when the nature of the distracting task changes in sensory modality. Participants typically took longer to respond when distracted, except for when the word onset was masked and the word was present auditorily. Oculomotor results indicated an increase in fixation durations (occasionally for the initial saccade latency as well) and a reduction of target fixations when participants were distracted by secondary information. These results suggest that secondary visual information can impact how humans search their environment in a fashion which increases their time to respond and impacts selective visual processing.

Mothers are often asked to use goal setting to help their children achieve optimal health. Before mothers can be successful, they must grasp the meaning and process of goal setting. Currently there is a glaring lack of published research regarding how goal setting is understood and experienced by mothers.

Show moreMothers are often asked to use goal setting to help their children achieve optimal health. Before mothers can be successful, they must grasp the meaning and process of goal setting. Currently there is a glaring lack of published research regarding how goal setting is understood and experienced by mothers. The purpose of this qualitative study was to examine the self-described understanding and experiences of mothers, regarding goal setting for their preschool children.Narrative Inquiry was used to explore mothers' experiences with goal setting. A purposive sample of mothers with children in a Voluntary Pre-Kindergarten program were recruited from the central Florida area. Data were obtained from demographic instruments and personal interviews using a semi-structured guide. Interviews were coded to ensure confidentiality, audio-recorded and transcribed. The narratives were analyzed for thematic emergence using content analyses techniques.Four major themes emerged: Parental Knowledge, Barriers, Process of Goal Setting, and Provider Involvement. Parental knowledge of goal setting was varied and unique; barriers of goal setting were focused on keeping children motivated and fear of failing; each participant used a different goal setting process and noted that provider involvement was limited at best. Data analysis revealed minimal effective communication between mothers and nursing providers about goal setting. As a result, mothers utilized unique goal setting processes for their children. Despite their varied understandings of goal setting and the goal setting process, these mothers were not stifled in their goal setting efforts. Educating nurses to communicate effectively with parents about goal setting with their children and addressing barriers they might face, is important. Incorporating goal setting into routine care can be an effective strategy to help patients attain health-related goals. Future research examining the perspective of goal setting from children and other caregivers and development of interventions to aid in goal attainment is needed.
