An Observation of Early Parent-Infant Social Interactions in Relation to the Emergence of Joint Attention in the Natural Environment

An Observation of Early Parent-Infant Social Interactions in Relation to the Emergence of Joint Attention in the Natural Environment

Date: May 2010
Creator: Pinsky, Karen
Description: Early interactions between parents and infants are thought to be critical of later development. In particular joint attention has been an area of research and investigations. This study sought to measure joint attention behaviors in infants from 5 to 33 weeks of age under naturalistic conditions: in the home with the mother as the interaction partner given no instructions. Videotapes of the infant-parent interactions were observed and data were collected on behaviors related to joint attention. Given observations occur at younger ages than other studies considered, engagement data results indicate increasing trends for 3 of the 5 infants observed while the direction of infant gaze results indicate patterns consistent with descriptions currently in the literature. Parent behavior data indicate high levels of support in engaging infant attention. Furthering an understanding of joint attention by observing at earlier ages in infant development may be useful in informing teaching programs for infants who have not developed joint attention skills.

An Observation System to Aid in the Evaluation and Implementation of Early Intervention Programs for Children with Autism

An Observation System to Aid in the Evaluation and Implementation of Early Intervention Programs for Children with Autism

Date: May 2009
Creator: Geving, Megan McGee
Description: Early and intensive behavioral intervention outcome research includes descriptions of intervention variables that may increase treatment success. This study was designed to develop an observation system that incorporates and expands on some of these variables. Measures include the number of interventionist teaching units, types of skills addressed during instruction, consequences programmed by interventionists, and engagement with teaching materials. This system allowed for a view of the differences in teaching behaviors among the participants. It is proposed that this observation system is a start toward standardized intervention measures that can be applied to evaluate varied treatment models. Such standardization can help in ensuring that all children have access to evidence-based services.

An Observational Investigation of On-Duty Critical Care Nurses' Information Behavior in a Nonteaching Community Hospital

An Observational Investigation of On-Duty Critical Care Nurses' Information Behavior in a Nonteaching Community Hospital

Date: May 2004
Creator: McKnight, Michelynn
Description: Critical care nurses work in an environment rich in informative interactions. Although there have been post hoc self-report survey studies of nurses' information seeking, there have been no observational studies of the patterns and content of their on-duty information behavior. This study used participant observation and in-context interviews to describe 50 hours of the observable information behavior of a representative sample of critical care nurses in a 20-bed critical care hospital unit. The researcher used open, in vivo, and axial coding to develop a grounded theory model of their consistent pattern of multimedia interactions. The resulting Nurse's Patient-Chart Cycle describes nurses' activities during the shift as centering on a regular alternation with the patient and the patient's chart (various record systems), clearly bounded with nursing "report" interactions at the beginning and the end of the shift. The nurses' demeanor markedly changed between interactions with the chart and interactions with the patient. Other informative interactions were observed with other health care workers and the patient's family, friends and visitors. The nurses' information seeking was centered on the patient. They mostly sought information from people, the patient record and other digital systems. They acted on or passed on most of the information ...

Observed Eye Contact between Selected Students and Teacher in the Music Making Process

Observed Eye Contact between Selected Students and Teacher in the Music Making Process

Date: August 2006
Creator: DeLong, D. Phillip
Description: High school band members (N=13) and their teacher were observed during six rehearsals of two contrasting band compositions over a six-week period. The contrasting compositions were selected by means of a detailed process between me (the researcher) and the teacher (the conductor). One 60-second excerpt of each composition was selected, during the performance of which, the students were observed. Three video tapings of each composition was done in order to capture occasions when the students would look up from their music. Using a technique adapted from Ekman (1997), the band members and teacher were then interviewed in order to reveal the reasons they recalled for looking up from their music. The results showed that the band members looked up in places where the teacher expected eye contact, that the frequency of eye contact changed little from one rehearsal to the next, and that the frequency of eye contact changed little between the two contrasting compositions. In all cases, the band members were able to recall the reasons for looking up from their music, a fact which led to a detailed analysis about the students' own thoughts while they were engaged in playing as an ensemble. The results are discussed in ...

Observing and Attending in a Delayed Matching-to-Sample Preparation in Pigeons

Observing and Attending in a Delayed Matching-to-Sample Preparation in Pigeons

Date: December 2008
Creator: Lovelace, Bryan S.
Description: Pigeons worked in a titrating delay match-to-sample (TDMTS) procedure in which selecting the correct comparison stimulus increased the delay between sample offset and comparison-array onset and incorrect comparison selections decreased that delay. Prior research in our lab has shown that the stable adjusted value of the retention interval is a curvilinear function of the observing response requirement. The current study examined the effect of the distribution and predictability of observing response requirements on adjusted retention interval values. The data show that unpredictable observing response requirements were more effective in attenuating the deleterious effects of delay on matching accuracy. The data have implications for our understanding of attending and encoding in performances involving remembering over short temporal durations.

Occlusion Tolerant Object Recognition Methods for Video Surveillance and Tracking of Moving Civilian Vehicles

Occlusion Tolerant Object Recognition Methods for Video Surveillance and Tracking of Moving Civilian Vehicles

Date: December 2007
Creator: Pati, Nishikanta
Description: Recently, there is a great interest in moving object tracking in the fields of security and surveillance. Object recognition under partial occlusion is the core of any object tracking system. This thesis presents an automatic and real-time color object-recognition system which is not only robust but also occlusion tolerant. The intended use of the system is to recognize and track external vehicles entered inside a secured area like a school campus or any army base. Statistical morphological skeleton is used to represent the visible shape of the vehicle. Simple curve matching and different feature based matching techniques are used to recognize the segmented vehicle. Features of the vehicle are extracted upon entering the secured area. The vehicle is recognized from either a digital video frame or a static digital image when needed. The recognition engine will help the design of a high performance tracking system meant for remote video surveillance.

The Occult as a Dramatic Device in Shakespearean Tragedy

The Occult as a Dramatic Device in Shakespearean Tragedy

Date: August 1967
Creator: Gray, Myrtle Seldon
Description: What this study will demonstrate is that Shakespeare's use of occult manifestations is not as superficial as it is sometimes said to be. On the contrary, it is the contention of this study that, especially in certain of the major tragedies, occult phenomena are integral to the main action, provide the play with essential motivation, and, in fact, are indispensable to a proper resolution.

The Occupational Aspirations and Expectations of Students Majoring In Jazz Studies At The University Of North Texas

The Occupational Aspirations and Expectations of Students Majoring In Jazz Studies At The University Of North Texas

Date: August 2001
Creator: Ramnunan, Karendra Devroop
Description: The purpose of this study was to identify the occupational aspirations and expectations of students majoring in jazz studies, and to investigate relationships between students' aspirations, expectations and selected variables including significant others, choice of school, instrument type, academic achievement, academic level, socioeconomic status, age, gender, and early jazz experience. All jazz studies majors enrolled at the University of North Texas during the Spring 2001 academic semester responded to a pilot test questionnaire (return rate 85%, N = 211). Frequencies, percentages, means, and standard deviations described the students' occupational aspirations, occupational expectations, backgrounds and training in jazz prior to entering UNT, and determined the extent to which parents, relatives, teachers, friends, and role models helped steer them into jazz (Pearson r, Spearman Rho and Point Biserial correlation coefficients provided). The low to moderate positive correlation between aspirations and expectations (r = 0.43) indicated that the two variables were different and measured different types of occupations. Fifty percent of students aspired to be jazz performers whereas 29.7% expected to be jazz performers. While 42% aspired to be engaged in a combination of occupational activities, 48% expected a combination of occupational activities. Only 4.7% aspired to teach; however, almost 16% expected to ...
