Perinatal Arterial Ischemic Stroke

Perinatal Stroke involves an often poorly understood neurocognitive events affecting the fetus and the new born with a potential for serious intellectual outcome.Our aim is to present a case study on the issue of neurocognitive defects on domains such as intellectual performance, attention and vigilance, executive functioning, visual perception, speed of processing, verbal learning and memory, and working memory on a 6 year old girl with perinatal arterial ischemic stroke.

Cognitive science has established widely used and validated procedures for evaluating working memory in numerous applied domains, but surprisingly few studies have employed these methodologies to assess claims about the impacts of visualizations on working memory. The lack of information visualization research that uses validated procedures for measuring working memory may be due, in part, to the absence of cross-domain methodological guidance tailored explicitly to the unique needs of visualization research. This paper presents a set of clear, practical, and empirically validated methods for evaluating working memory during visualization tasks and provides readers with guidance in selecting an appropriate working memory evaluation paradigm. As a case study, we illustrate multiple methods for evaluating working memory in a visual-spatial aggregation task with geospatial data. The results show that the use of dual-task experimental designs (simultaneous performance of several tasks compared to single-task performance) and pupil dilation can reveal working memory demands associated with task difficulty and dual-tasking. In a dual-task experimental design, measures of task completion times and pupillometry revealed the working memory demands associated with both task difficulty and dual-tasking. Pupillometry demonstrated that participants’ pupils were significantly larger when they were completing a more difficult task and when multitasking. We propose that researchers interested in the relative differences in working memory between visualizations should consider a converging methods approach, where physiological measures and behavioral measures of working memory are employed to generate a rich evaluation of visualization effort.

Calculation Procedures

Acalculia is an acquired disorder of calculating which occures isolated or with association with aphasia and mild cognitive impairment. We described a case study of 37-year-old Ms. R. after hemorrhage and ischemia with Broca aphasia and acalculia in the article. Ms. R. was assessed by own diagnostic test for acalculia, by test for aphasia and cognitive functions. The aim of the study was to investigate the link between Ms R.´s acalculia, Broca aphasia nad mild cognitive impairment. Assessment revealed Broca aphasia, verbal apraxia, alexia, agraphia, poor attention, weak working memory and poor later recall of remembered words. Assessment of acalculia showed transcoding impairments, disorders of aritmetic fact retrieval and disorders of calculation procedures. Poor working memory and alexia influenced transcoding of numbers. Alexia is also manifested in comprehension of word problems. Counting backward and counting dots were complicated by poor concentration of attention and weak working memory. Symptoms of aphasia, acalculia and mild cognitive impairment affected each other.

Individual Choices

Choices are often difficult to make by patients with Alzheimer Dementia. They often become acutely confused when faced with too many options because they are not able to retain in their working memory enough information about the various individual choices available. In this case study, we describe how an essentially simple benign task (choosing a dress to wear) can rapidly escalate and result in a catastrophic outcome. We examine what went wrong in the patient/caregiver interaction and how that potentially catastrophic situation could have been avoided or defused.

I argue that current models of aural skills instruction are too strongly linked to music theory curricula. I examine harmonic dictation as a case study, demonstrating that the system of roman-numeral/inversion-symbol labels can interfere with our ability to determine what exactly students are hearing and can distract students from more directly perceptual goals. A pilot study suggests that focusing on bass lines and schemata may make our harmonic dictation training more relevant to perception. I propose that a skill is “truly aural” to the extent that it engages working memory with minimal knowledge-based mediation. Finally, I consider the current state of aural skills instruction and suggest a number of curricular revisions. The more radical proposals call for redesigning aural skills classes to focus on perceptual skills and relocating knowledge-mediated listening to the music theory classroom. Other proposals take a more measured approach to integrating perceptual skills with otherwise traditional curricula.
