Performance Strategies

Verbal reports were collected from experienced performers during acquisition trials of a novel throwing task and summarized as cognitive performance strategies. These strategies were incorporated in the practice regimen of 8 novices with no sport experience who learned the same task. A control group of 8 novices practiced the task without the experts' cognitive performance strategies. The performance of the novices who used the strategies was similar to that of the experts and significantly better than the performance of the control novices.

This study compared two different motor skill modeling presentations (with and without goal display) in visual and audio-visual conditions for learning a complex skill (basketball jump shot) to evaluate the importance of (a) audio information and (b) goal observation in motor performance kinematics. Specifically, we sought to understand whether the simultaneous presentation of auditory and visual patterns could usefully direct the learner’s attention from goal to pattern stimuli. I selected 40 students ( Mage = 20.47 years) who had no prior experience with the basketball jump shot or free throw and randomly assigned them into four groups: Pattern/Visual, Pattern/Audio-Visual, Pattern-Goal/Visual, and Pattern-Goal/Audio-Visual. Participants in the pattern-only groups watched only the skilled motor pattern, while those in the pattern-goal groups watched both the pattern and its outcome. Participants in the visual-only groups simply watched the visual pattern, while those in audio-visual groups saw and heard the pattern; we sonified the angular velocity of the skilled performer’s elbow joint. Participants then performed in two conditions with and without balls. On all dependent variables, the participants’ performance following the audio-visual presentations was better than when following the visual-only presentations. In addition, the participants’ performance in pattern-only groups was better than in pattern-goal groups, but this improved pattern-only performance was far less extensive in the audio-visual than in the visual-only group. In sum, complex motor skill imitation was enhanced by an audio pattern of elbow angular velocity in support of generalist theories of imitation learning.

Abstract. Several studies have shown that Continuous Performance Tests (CPT) can diagnose Attention Deficit Hyperactivity Disorder (ADHD) better than other tests. Research reporting comparisons of two or more CPT-type tests is scarce. The purpose of the study was to compare the Mathematics Continuous Performance Test (MATH-CPT) with another CPT-type test (CPT II) and a questionnaire (the Brown Scale). The comparison was carried out by looking at correlations among subscales and checking the precision of detecting ADHD. Ninety-five high school and college students participated in the study, 41 with ADHD were the research group and 54 were the control group. The participants performed the two tests and answered the questionnaire. The results showed that the MATH-CPT correctly identified 74.50% of the participants of both groups as compared to the 71.60% of the CPT II. Correlations between the two CPT-type tests were moderate; however, they were similar to correlations found in other studies comparing similar tools. The MATH-CPT, final attention formula, showed significant correlations with the Brown scales, while the CPT II, confidence index associated with ADHD assessment, showed nonsignificant correlations with the questionnaire. The study indicated that MATH-CPT can be used with a clinical population of ADHD and for research purposes.

Chess Playing

Chess playing has a significant role in participants’ resources allocation, both at a psychological level, but mostly concerning the cognitive resources. The aim of the present study was to examine the effect of chess playing on the intellectual development of primary-class students. 67 children were tested using the Raven Standard Progressive Matrices and were distributed in three different groups according to their experience with chess, namely: the control group (formed by students with no experience with chess playing), the beginners group (students with less than one year in chess playing training) and the advanced group (children with more than two years experience with chess). Results indicated that chess playing had a significant effect on the SPM performance, indicating that those in the advanced group performed significantly better than those in the control or in the beginners group. Conclusions of this study tap into the benefits of playing chess with a focus on the children’s’ cognitive development.

Background: Patients positive for three types of antiphospholipid antibodies (aPLs) (triple positivity) have been identified at a high risk for thrombotic events. However, the clinical significance of isolated lupus anticoagulant (LAC) positivity is debated. Objectives: To investigate the clinical relevance of isolated LAC. Patients/Methods 456 patients were enrolled in this study; 66 antiphospholipid syndrome patients and 390 control patients. The control group existed of autoimmune patients (n=91), patients with thrombosis but without aPLs (n=127) and normal controls (n=172). The criteria LAC, anti-cardiolipin (anti-CL) and anti-beta2glycoprotein I (anti-β2GPI) IgG and IgM and the non-criteria IgA anti-CL and anti-β2GPI, anti-domain I (anti-DI) of β2GPI IgG and anti-phosphatidylserine/prothrombin (anti-PS/PT) IgG and IgM were detected according to the ISTH guidelines for solid phase assays. Results: 70 patients were positive for LAC, of which 44 were negative for both anti-β2GPI and anti-CL. We found that isolated LAC proved to be strongly associated with vascular thrombosis (Odds ratio (OR) (95% CI) 7.3 (3.3-16.1)), even better than triple positive samples (OR 4.3 (1.6-12.2)). The titers of the anti-PS/PT IgG and IgM were significantly higher in triple positivity samples compared to samples with isolated LAC positivity. The majority of single LAC positives were anti-PS/PT negative. We observed that LAC positivity was weaker in isolated LAC positive patients compared to LAC activity in triple positive patients. Conclusions: Isolated LAC was highly associated with thrombosis. The presence of anti-PS/PT could not explain LAC positivity in isolated LAC. Isolated LAC showed a weaker LAC activity compared to triple positive patients.

Cross-sectional studies suggest that motor skill learning is associated with working memory (WM) and white matter integrity (WMI). However, it has not been established whether motor skill learning improves WM performance, and information on its neural mechanisms have not been clearly elucidated. Therefore, this study compared WM and WMI across time points prior to and following football juggling learning, in early adulthood (18–20 years old), relative to a control group. Study participants in the experimental group were subjected to football juggling for 10 weeks while participants in the control category went on with their routine life activities for the same period of time and were not involved in the learning-related activities. Data on cognitive measurements and that from diffusion tensor imaging (DTI) were collected before and after learning. There was a significant improvement in WM performance of the experimental group after motor learning, although no improvement was observed in the control group. Additionally, after learning, DTI data revealed a significant increase in functional anisotropy (FA) in the genu of corpus callosum (GOCC) and the right anterior corona radiata (R.ACR) in the experimental group. Moreover, the better WM associated with football juggling learning was correlated to a higher FA. Mediation analysis suggested that FA in the GOCC acts as a mediation variable between football juggling learning and WM. These findings show that motor skill learning improves the WM and remodels WMI in early adulthood. With a particular emphasis on the importance of WMI in motor skill learning and WM, this study also revealed the possible neural mechanisms mediated by WMI.

The infection of Enterococcus faecalis and its interacting microorganisms in the root canal could cause persistent apical periodontitis (AP). Antibacterial root canal sealer has favorable prospects to inhibit biofilms. The purpose of this study was to investigated the antibacterial effect of root canal sealer containing dimethylaminododecyl methacrylate (DMADDM) on persistent AP in beagle dogs for the first time. Persistent AP was established by a two-step infection with Enterococcus faecalis and multi-bacteria (Enterococcus faecalis, Lactobacillus acidophilus, Actinomycesnaeslundii, Streptococcus gordonii). Root canal sealer containing DMADDM (0%, 1.25%, 2.5%) was used to complete root canal filling. The volume of lesions and inflammatory grade in the apical area were evaluated by cone beam computer tomography (CBCT) and hematoxylin-eosin staining. Both Enterococcus-faecalis- and multi-bacteria-induced persistent AP caused severe apical destruction, and there were no significant differences in pathogenicity between them. DMADDM-modified sealer significantly reduced the volume of periapical lesion and inflammatory grade compared with the control group, among them, the therapeutic effect of the 2.5% group was better than the 1.25% group. In addition, E.faecalis-induced reinfection was more sensitive to the 2.5% group than multi-bacteria reinfection. This study shows that root canal sealer containing DMADDM had a remarkable therapeutic effect on persistent AP, especially on E. faecalis-induced reinfection.
