Playing With BEARS: Balancing Effort, Accuracy, and Response Speed in a Semantic Feature Verification Anomia Treatment Game

Purpose The purpose of this study was to develop and pilot a novel treatment framework called BEARS (Balancing Effort, Accuracy, and Response Speed). People with aphasia (PWA) have been shown to maladaptively balance speed and accuracy during language tasks. BEARS is designed to train PWA to balance speed–accuracy trade-offs and improve system calibration (i.e., to adaptively match system use with its current capability), which was hypothesized to improve treatment outcomes by maximizing retrieval practice and minimizing error learning. In this study, BEARS was applied in the context of a semantically oriented anomia treatment based on semantic feature verification (SFV). Method Nine PWA received 25 hr of treatment in a multiple-baseline single-case series design. BEARS + SFV combined computer-based SFV with clinician-provided BEARS metacognitive training. Naming probe accuracy, efficiency, and proportion of “pass” responses on inaccurate trials were analyzed using Bayesian generalized linear mixed-effects models. Generalization to discourse and correlations between practice efficiency and treatment outcomes were also assessed. Results Participants improved on naming probe accuracy and efficiency of treated and untreated items, although untreated item gains could not be distinguished from the effects of repeated exposure. There were no improvements on discourse performance, but participants demonstrated improved system calibration based on their performance on inaccurate treatment trials, with an increasing proportion of “pass” responses compared to paraphasia or timeout nonresponses. In addition, levels of practice efficiency during treatment were positively correlated with treatment outcomes, suggesting that improved practice efficiency promoted greater treatment generalization and improved naming efficiency. Conclusions BEARS is a promising, theoretically motivated treatment framework for addressing the interplay between effort, accuracy, and processing speed in aphasia. This study establishes the feasibility of BEARS + SFV and provides preliminary evidence for its efficacy. This study highlights the importance of considering processing efficiency in anomia treatment, in addition to performance accuracy. Supplemental Material https://doi.org/10.23641/asha.14935812

Speed And Accuracy

Volleyball players and nonplayers were compared for speed and accuracy of performance in a task involving detection of the presence of a volleyball in rapidly presented slides of a volleyball situation. Slides depicted both game and nongame situations, and subjects performed the task in both noncompetitive and competitive conditions. For all subjects, game information was perceived more quickly and accurately than nongame information. In competition all subjects showed decreased perceptual accuracy and no change in criterion, supporting the Easterbrook (1959) notion of perceptual narrowing with stress. Very large accompanying increases in response speed, however, suggested that competition may induce adoption of a particular speed-accuracy trade-off. Cognitive flexibility in the adoption of particular speed-accuracy trade-offs is discussed with reference to volleyball.

The Relationship ◽

Accuracy Tradeoff

Previous research suggests a relationship between neuroticism (N) and the speed-accuracy tradeoff in speeded performance: High-N individuals were observed performing less efficiently than low-N individuals and compensatorily overemphasizing response speed at the expense of accuracy. This study examined N-related performance differences in the serial mental addition and comparison task (SMACT) in 99 individuals, comparing several performance measures (i.e., response speed, accuracy, and variability), retest reliability, and practice effects. N was negatively correlated with mean reaction time but positively correlated with error percentage, indicating that high-N individuals tended to be faster but less accurate in their performance than low-N individuals. The strengthening of the relationship after practice demonstrated the reliability of the findings. There was, however, no relationship between N and distractibility (assessed via measures of reaction time variability). Our main findings are in line with the processing efficiency theory, extending the relationship between N and working style to sustained self-paced speeded mental addition.

Speed And Accuracy

In most work contexts, several performance goals coexist, and conflicts between them and trade-offs can occur. Our paper is the first to contrast a dual goal for speed and accuracy with a single goal for speed on the same task. The Sternberg paradigm (Experiment 1, n = 57) and the d2 test (Experiment 2, n = 19) were used as performance tasks. Speed measures and errors revealed in both experiments that dual as well as single goals increase performance by enhancing memory scanning. However, the single speed goal triggered a speed-accuracy trade-off, favoring speed over accuracy, whereas this was not the case with the dual goal. In difficult trials, dual goals slowed down scanning processes again so that errors could be prevented. This new finding is particularly relevant for security domains, where both aspects have to be managed simultaneously.

Introduction Lesser tuberosity osteotomy (LTO) during anatomic total shoulder arthroplasty has a 13% nonunion rate. Treatment for LTO nonunion is controversial and poorly described in the literature. The purpose of this study was to compare the surgical and nonsurgical treatment outcomes of LTO nonunion. Methods A retrospective case series of 9 consecutive patients with LTO nonunion after primary anatomic shoulder arthroplasty at 1 institution from 2010 to 2016 were studied. Outcomes measured were radiographic evaluation of LTO on axillary X-ray, clinical range of motion (ROM), subscapularis strength, and pain at the time of LTO nonunion diagnosis and after either conservative care or surgical repair of the LTO nonunion. Results LTO nonunion was treated surgically in 4 and conservatively in 5 patients with average follow-up of 30 and 22 months, respectively. There were no significant differences in age, sex, or smoking status between groups. Treatment decision was a shared model of surgeon and patient. Displaced LTO nonunion was treated surgically in 2 and conservatively in 3 patients. There were no differences in LTO union rate of 50% in the surgical versus 60% in the conservative group. Abdominal compression test was abnormal in 50% of surgical versus 40% of conservative groups. At follow-up, ROM was lower in the surgical group with 128° forward elevation (FE) and 33° external rotation (ER) compared to 148° FE and 62° ER. Only 1 patient with LTO nonunion required conversion to reverse replacement. Conclusion LTO nonunion after shoulder arthroplasty is rare. Surgical repair of LTO nonunion does not significantly improve clinical or radiographic outcomes compared to conservative care.

Background. Guillain-Barré syndrome (GBS) is the most common cause of flaccid paralysis, with about 100,000 people developing the disorder every year worldwide. Recently, the incidence of GBS has increased during the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) epidemics. We reviewed the literature to give a comprehensive overview of the demographic characteristics, clinical features, diagnostic investigations, and outcome of SARS-CoV-2-related GBS patients. Methods. Embase, MEDLINE, Google Scholar, and Cochrane Central Trials Register were systematically searched on 24 September 2020 for studies reporting on GBS secondary to COVID-19. Results. We identified 63 articles; we included 32 studies in our review. A total of 41 GBS cases with a confirmed or probable COVID-19 infection were reported: 26 of them were single case reports and 6 case series. Published studies on SARS-CoV-2-related GBS typically report a classic sensorimotor type of GBS often with a demyelinating electrophysiological subtype. Miller Fisher syndrome was reported in a quarter of the cases. In 78.1% of the cases, the response to immunomodulating therapy is favourable. The disease course is frequently severe and about one-third of the patients with SARS-CoV-2-associated GBS requires mechanical ventilation and Intensive Care Unit (ICU) admission. Rarely the outcome is poor or even fatal (10.8% of the cases). Conclusion. Clinical presentation, course, response to treatment, and outcome are similar in SARS-CoV-2-associated GBS and GBS due to other triggers.

Abstract Background and Study Aims Primary intraspinal primitive neuroectodermal tumors (PNETs) account for ∼0.4% of all intraspinal tumors, but information about these tumors in the medical literature is limited to single case reports. We report four cases of primary intraspinal PNETs and present a systematic literature review of the reported cases. Materials and Methods We retrospectively reviewed and analyzed the clinical data of 4 patients with primary intraspinal PNETs who underwent neurosurgical treatment at our clinic between January 2013 and January 2020, and of 32 cases reported in the literature. Results The female-to-male ratio was 2.6:1. The mean patient age was 21.42 ± 15.76 years (range: 1–60 years), and patients <36 years of age accounted for 83.30% of the study cohort. Progressive limb weakness and numbness were the chief symptoms (accounting for ∼55.6%). The mean complaint duration was 0.89 ± 0.66 months for males and 2.72 ± 3.82 months for females (p = 0.028). Epidural (41.7%) was the most common site, and thoracic (47.3%) was the most frequent location. Most PNETs were peripheral, and magnetic resonance imaging (MRI) appearance was isointense or mildly hypointense on T1-weighted images and hyperintense on T2-weighted images. Homogeneous contrast enhancement was observed. The 1-year survival rate of patients who underwent chemoradiation after total or subtotal lesion resection was better compared with patients who did not undergo chemotherapy, radiotherapy, or total or subtotal resection. The modality of treatment was associated with survival time (p = 0.007). Conclusion Primary intraspinal PNETs mainly occur in young people with a female preponderance. In patients with a rapid loss of lower limb muscle strength and large intraspinal lesions on MRI, PNETs should be considered. Surgical resection and adjuvant radio chemotherapy are key prognostic factors.

The purpose of this study was to carry out a literature review on the effectiveness of the validation method (VM) in job satisfaction and motivation of care professionals working with older people in nursing homes. The review was carried out in specialised databases: Scopus, PsychINFO, PubMed, Web of Science (WOS), Google Scholar, Scielo, and Cochrane Database of Systematic Reviews. 9046 results were obtained, out of which a total of 14 studies met the inclusion criteria: five quantitative, four qualitative, one single case series, two quasi-experimental and two mixed methods studies. The results of the analysed studies report that the VM can be an effective tool that facilitates communication and interaction in care, reducing levels of stress and job dissatisfaction among care professionals. The VM facilitates communication between professionals and older people with dementia, and improves the management of complex situations that may arise in care, directly influencing a reduction in work stress and increasing job satisfaction.
