Visual Kinematic Feedback

698 Words3 Pages

The purpose of this study was to examine the effects of the presence and frequency of online augmented visual kinematic feedback (AVKF) and clinician-provided perceptual feedback would lead to perceptually judge improved accuracy for selected speech motor targets (SMT). The targeted population in this study consisted of 2 adults with apraxia of speech (AOS) and contaminant aphasia. In this case they used a 45-year old right handed female and a 39-year old male, both presenting with AOS and aphasia after having a stroke. The female participant presented 26 months after her stroke that showed mild-moderate aphasia and mild moderate AOS and had previously received Speech Language Pathology treatment. Their male participant presented after 2 years of his stroke. He was diagnosed with mild-moderate aphasia and severe AOS with no SLP treatment. One of the independent variables of this study was EMA. EMA, electromagnetic midsagittal articulography is a technology used to deliver the online AVKF. This exam was conducted in a sound treated IAC booth. Clinician then glued sensors to specific parts: like their lips, tongue and teeth. This then gave them a visual display in a monitor which showed a defined target and if it was correct according to the clinician. A dependent variable of this study was the SMT’s. They were …show more content…

The productions of the participants were digitally recorded and online perceptual judgments of segmented and intersegment distortions of accuracy were made by clinician. This helps the clinician and patients see if they hit a target with a red or green light. The study was reviewed by two judges for variability. Inter and intra judge reliability for perceptual accuracy was high. The average for 3STM’s was 88% from one judge and 95% from the other judge. The final results of the study showed positive acquisition and generalization effects for both

Also, the Bodyscope is a very practical device. Unlike state of the art devices that needs to be worn around the wrist, attached to phones or integrated with cameras; the Bodyscope latches directly with the part of the body responsible for sending out these acoustic signals, that is, the neck or throat. 4. What assumptions are the authors making?

The client had an L-hemisphere CVA on 8/11/10. After the stroke, the client was admitted for a 5 day acute care hospitalization and then into an inpatient rehab setting for six weeks for one hour every day. Through a speech evaluation, the client was diagnosed with a mild anomic aphasia and mild apraxia of speech. The client 's goals are to improve her mobility, communication, and return home. This session was a re-assessment six months after she was discharged from the inpatient rehab setting.

Broca's Aphasi Video Analysis

228 Words | 1 Pages

From the text, Broca’s aphasia is defined as an expressive language disorder resulting from damage to the Broca’s area of the frontal lobe of the brain. Strokes are common causes of most aphasias and one type of stroke known as an Ischemic stroke, happens when the blood supply to the brain is repressed because of a blockage in an artery. The girl in the video named Sarah suffered from aphasia and it was fairly obvious because of the symptoms she displayed. For example, I noticed that her speech was very slow and effortful and that she had a hard time putting words together to form complete sentences. Also, her speech was very dysfluent as she said “um” a lot and spoke in short telegraphic phrases.

Operant Response Generalization Case Study

912 Words | 4 Pages

1. When discussing programming of generality of behavior, with regards to training situation vs the target situation training situation refers to the settings in which the behaviour is initially strengthened, and the target situation refers to the settings in which we want the behaviour to occur 6. The teaching of a rule may facilitate operant stimulus generalization because generalization by teaching an individual to program common stimuli in different novel situations. The general factor for programming for generalization that seems to be operating is programming common stimuli. For example, telling a child not to play with their food during dinner at home can program the child to rehearse this rule in other settings such as restaurants and other people’s houses.

Multisensory Integration

871 Words | 4 Pages

Our brain is constantly flooded by sensory signals from a number of different modalities; these signals must be integrated and attended to appropriately in order to create an accurate perception of our environment. When auditory and visual events occur simultaneously within close proximity to each other, though at disparate locations, source localisation for one modality interacts with that for the other modality in a characteristic manner (Bermant & Welsh, 1976) - referred to as cross-modal bias. The two locations are averaged with a greater weighting given to the stimulus with the greater spatial reliability, typically the visual stimulus. This results in the spatial location of the auditory stimulus appearing to be closer to the visual stimulus

Childhood Apraxia Of Speech Essay

1402 Words | 6 Pages

Childhood apraxia of speech (CAS) is a childhood neurological speech sound disorder which is characterized by impairment of the consistency and precision of movements underlying speech with the main impairment consisting of programming and/or planning spatiotemporal aspects of movement sequences resulting in speech sound prosody and production errors (American Speech-Language-Hearing Association, 2007). CAS is present in pediatric populations as contrasted with Apraxia of Speech (AOS) which is an adult diagnosis. Childhood apraxia of speech is considered controversial by some researchers. Shriberg (n.d.) argues that although the diagnostic term is undoubtedly accurate, it has not yet been backed up by sufficient or compelling research

Mental Rotation Experiment Essay

Secondly, because the experiment was conducted online, it is not clear whether the participants actually read and followed the instructions. Prior to the trails, the instructions reminded the participants that “accuracy is more important than speed”. It is possible that the participants missed the instructions and tried to strive for better reaction times rather than accuracy. In addition, the sample size was relatively small compared to the previous experiments which could be another confounding factor. One possible direction for future study is to examine the effects of different visual stimuli used on the performance of MRT.

Classical Conditioning And Observational Learning Analysis

2548 Words | 11 Pages

Introduction Learning enables you as an individual, to gain more knowledge about something which you have never learned about. Learning also has to do with past experiences which are influenced by behavioural changes (Weiten, 2016). There are different types of ways to learn; through, classical conditioning, operant conditioning and observational learning which will be discussed and analysed in the essay.   Behaviourism Behaviourism is considered one of the main subjects in psychology and the two main people who founded behaviourism were, Burrhus Frederic Skinner, also known as B.F Skinner and Ivan Pavlov who were famous for the work they did on classical and operant conditioning (Moderato & Presti, 2006). According to Moderato and Presti

The Influence Of CAPD In Language

Adults with diseases that affect the CNS and children with developmental disorders of language or learning disorders have difficulty understanding spoken language, even when they have knowledge of it. If any of these individuals in addition to their condition had a DPAC latter certainly contribute significantly to their understanding problems. Thus, patients with a lesion in the right hemisphere temporal and parietal area have difficulty in analyzing acoustic information as well as pitch, loudness, tempo, and rhythm in speech which help us understand the structure and meaning of an utterance..

INTRODUCTION Have you ever thought on how people explain about behaviour? How do we know when learning process has occurred? Learning is permanent change that happened in the way of your behaviour acts, arises from experience one’s had gone through. This kind of learning and experience are beneficial for us to adapt with new environment or surrounding (Surbhi, 2018). The most simple form of learning is conditioning which is divided into two categories which are operant conditioning and classical conditioning.
