Does the Provision of an Intensive and Highly Focused Indirect Corrective Feedback Lead to Accuracy?

Description: This thesis imparts the outcomes of a seven-week long quasi-experimental study that explored whether or not L2 learners who received intensive and highly focused indirect feedback on one type of treatable error - either the third person singular -s, plural endings -s, or definite article the - eventually become more accurate in the post-test as compared to a control group that did not. The paired-samples t-test comparing the pre-test and post-test scores of both groups demonstrates that the exp… more

Should Corrective Feedback Come Before or After Responding to Establish a "New" Behavior?

Description: The purpose of this study was to determine the optimal form and timing of feedback to establish a "new" behavior. It examined the relative effectiveness of delivering a corrective feedback immediately before the learner responds to a previously incorrect trial as compared to delivering a corrective feedback immediately after the incorrect response is made. Corrective feedback delivered immediately before the next opportunity to respond produced better learning than corrective feedback delivered… more

Measurement of Feedback Inhibition In Vivo and Selection of ATCase Feedback Altered Mutants in Salmonella typhimurium

Description: Aspartate transcarbamoylase (ATCase; encoded by pyrBI genes) is one of the most studied regulatory enzymes in bacteria. It is feedback inhibited by cytidine triphosphate (CTP) and activated by adenosine triphosphate (ATP). Much is known about the catalytic site of the enzyme, not nearly as much about the regulatory site, to which CTP binds. Until now a positive selection for feedback-modified mutants was not available. The selection we have developed involves the use of a pyrA deletion in S. ty… more

How You Correct Matters

Description: Feedback is used in a variety of contexts to train staff and to teach individuals new skills. Despite its popularity, there is no consensus on how to deliver it. Different measures have been used to evaluate the effectiveness of feedback, such as accuracy of responses and the sequencing of feedback delivery. The purpose of this study was to compare two feedback procedures and to explore new ways to measure the effectiveness of feedback. Four undergraduate students were exposed to two conditions… more

The Effects of a Feedback Package on the Facial Orientation of a Young Girl with Autism During Restricted and Free Operant Conditions

Description: A multiple baseline design across activities and people was used to assess the effectiveness of a feedback package on the facial orientation of a young girl with autism. During baseline, observations indicated low rates of facial orientation and high rates of gaze avoidance during conversation (restricted operant) and play (free operant) conditions. After treatment, facial orientation rates increased and gaze avoidance rates decreased to levels similar to typically-developing peers and maintain… more

Human Learned Helplessness: Uncontrollable Negative Feedback or Total Amount of Negative Feedback?

Description: To determine if learned helplessness results from lack of control over negative events or simply the number of negative events experienced, 60 university students were assigned to one of five treatments: controllable low negative, uncontrollable low negative, controllable high negative, uncontrollable high negative, and no treatment. Backward digit and letter span tasks served as test tasks. The generally nonsignificant results were discussed as possibly due to a procedural error. Further resea… more

Stabilization and Performance Improvement of Control Systems under State Feedback

Description: The feedback control system is defined as the sampling of an output signal and feeding it back to the input, resulting in an error signal that drives the overall system. This dissertation focuses on the stabilization and performance of state feedback control systems. Chapters 3 and 4 focus on the feedback control protocol approaching in the multi-agents system. In particular, the global regulation of distributed optimization problems has been considered. Firstly, we propose a distributed optimi… more

Computer Virus Spread Containment Using Feedback Control.

Description: In this research, a security architecture based on the feedback control theory has been proposed. The first loop has been designed, developed and tested. The architecture proposes a feedback model with many controllers located at different stages of network. The controller at each stage gives feedback to the one at higher level and a decision about network security is taken. The first loop implemented in this thesis detects one important anomaly of virus attack, rate of outgoing connection. Tho… more

When to correct errors when teaching a new task to children with autism

Description: The purpose of this experiment was to investigate Tosti's proposal about the timing of feedback. The study examined whether it is better to correct immediately after the error occurs or whether it is better to wait until immediately before the next opportunity to respond. In addition, it aimed to determine whether corrections delivered at different times produced different learner affects. Four children with autism were taught to label two sets of pictures under the two different conditions. Re… more

Analysis of Leadership Perceptions Using Multirater Feedback.

Description: Performance improvement intervention begins with assessment. How that assessment is interpreted can mean the difference between success and failure. Previous research of 360-degree feedback instruments has tried to reconcile the differences between multiple rater groups. Rather than searching for agreement, this research proposes to understand the meaning of the differences using multirater feedback. Individuals determine ratings based upon their own perspective and building upon the understand… more
