User-driven design of robot costume for child-robot interactions among children with cognitive impairment

The involvement of arts and psychology elements in robotics research for children with cognitive impairment is still limited. However, the combination of robots, arts, psychology and education in the development of robots could significantly contribute to the improvement of social interaction skills among children with cognitive impairment. In this article, we would like to share our work on building and innovating the costume of LUCA's robot, which incorporating the positive psychological perspectives and arts values for children with cognitive impairment. Our goals are (1) to educate arts students in secondary arts school on the importance of social robot appearance for children with cognitive impairment, and (2) to select the best costume for future child-robot interaction study with children with cognitive impairments

Aesthetic, Ethical, and Cognitive Value

This paper addresses two recent debates in aesthetics: the ‘moralist debate’, concerning the relationship between the ethical and aesthetic evaluations of artworks, and the ‘cognitivist debate’, concerning the relationship between the cognitive and aesthetic evaluations of artworks. Although the two debates appear to concern quite different issues, I argue that the various positions in each are marked by the same types of confusions and ambiguities. In particular, they demonstrate a persistent and unjustified conflation of aesthetic and artistic value, which in turn is based on a more general failure to explicitly tackle the demarcation of aesthetic value. As such, the claims of each side are rendered ambiguous in respect of the relation that is supposed to hold between all these types of value and artistic value. These issues are discussed in light of a recent argument proposed by Matthew Kieran, to undermine, to some extent, the conceptual distinction between aesthetic, cognitive-ethical, and artistic values in our appraisal of art works. In rejecting his argument, I defend the conceptual distinction and a pluralistic conception of artistic value that allows for cognitive and ethical values to count as artistic, but not aesthetic, values

Using neurite orientation dispersion and density imaging and tracts constrained by underlying anatomy to differentiate between subjects along the Alzheimer's disease continuum

OBJECTIVE: To assess the involvement of the white matter of the brain in the pathology of Alzheimer’s disease. Using Neurite Orientation Density and Dispersion Imaging (NODDI) and the probabilistic white matter parcellation tool Tracula as a means for understanding whether alterations in the white matter underlie changes in perceived cognitive abilities across the spectrum from health aging to Alzheimer’s disease. METHOD: Data were obtained from 28 participants in the Health Outreach Program for the Elderly (HOPE) at the Boston University Alzheimer’s Disease Center (BU ADC) Clinical Core Registry. MRI scans included an MPRAGE T1 scan, multi-b shell diffusion scan and a High Angular Resolution Diffusion Imaging scan (HARDI). Scans were processed with Freesurfer v6.0 and the NODDI Python2.7 toolkit. The resulting data included the orientation dispersion index (ODI) and Fractional Anisotropy (FA) values for cortical and subcortical regions in the DKT atlas space as well as specific Tracts Constrained by Underlying Anatomy (TRACULA) measurements for 18 specific established white matter tracts. Statistical models using measures of pathway integrity (FA and ODI data) were used to assess relationships with Informant Cognitive Change Index (ICCI), self-described Cognitive Change Index (CCI), and Clinical Dementia Rating (CDR) values. RESULTS: Measures of white matter integrity within several tracts predicted ICCI and CDR well in statistical models. FA and ODI values of the bilateral superior longitudinal fasciculi, inferior longitudinal fasciculi, and the cingulum bundle tracts were all related to ICCI and CDR. None of the known tracts’ FA or ODI values were related to CCI. CONCLUSIONS: Measures of white matter pathway integrity were predictive of ICCI and CDR scores but not CCI. These finding support the notion that self-report of cognitive abilities may be compromised by alterations in insight and reinforce the need for informed study partners and clinical ratings to evaluate potential MCI and AD

Culture, Mind, and the Brain: Current Evidence and Future Directions

Current research on culture focuses on independence and interdependence and documents numerous East-West psychological differences, with an increasing emphasis placed on cognitive mediating mechanisms. Lost in this literature is a time-honored idea of culture as a collective process composed of cross-generationally transmitted values and associated behavioral patterns (i.e., practices). A new model of neuro-culture interaction proposed here addresses this conceptual gap by hypothesizing that the brain serves as a crucial site that accumulates effects of cultural experience, insofar as neural connectivity is likely modified through sustained engagement in cultural practices. Thus, culture is “embrained,” and moreover, this process requires no cognitive mediation. The model is supported in a review of empirical evidence regarding (a) collective-level factors involved in both production and adoption of cultural values and practices and (b) neural changes that result from engagement in cultural practices. Future directions of research on culture, mind, and the brain are discussed

Technique of the Joint Use of System Dynamics and Cognitive Analysis for Reengineering of Complex Economic and Social-Political Systems

The technique of the joint use of system dynamics and cognitive analysis for reengineering of complex systems has been proposed. The use of the system dynamics technique at the initial stage of reengineering processes faces the certain difficulties due to the fact of presence of large amount of parameters.It is rather difficult to choose correctly all levels’ and variables’ initial values and change rates. Arbitrary assignment of initial values leads to radical incorrect reengineering procedures. In order to avoid this undesirable result the approach presented in the article assumes the implementation of the cognitive analysis technique at the initial stage. After revelation of fundamental trends of development and screening of insignificant factors system dynamics methodology is proposed to be implementedcognitive analysis, system dynamics, reengineering, impulse oriented weighted graphs, qualitative assessment of processes, emergency management

The Contribution of Blood Serum Biomarkers to the Prediction of Cognitive Decline by fMRI and Apolipoprotein-E in Healthy Older Adults

Biomarkers are a promising approach to the prediction and early intervention of Alzheimer\u27s disease. We demonstrated that cortical functional MRI (fMRI) activation during a semantic memory task and apolipoprotein-E ?4 allele inheritance (APOE?4) effectively predicted cognitive decline after 18-months in healthy, asymptomatic elders. Hippocampal volume added modest prediction, while AD family history and demographics were ineffective. Previous studies have linked plasma homocysteine (tHcy), vitamin B12 and creatinine values to cognitive funcitoning, cortical atrophy, hippocampal atrophy and neuropathology, and vascular integrity. Here we incorporated total plasma homocysteine (tHcy), B12 creatinine values into our previous predictive models. Of 78 healthy elders, 27 (34.6%) exhibited significant cognitive decline after 18-months. tHcy, but not B12 or creatinine, was marginally positively correlated with cortical semantic memory fMRI activation, particularly in stable participants. Logistic regression showed that tHcy, when added to APOE?4 and cortical fMRI, was a significant predictor of outcome and strengthed the already significant model (p = .007; C = .80 and R2 = .37). However, control for B12 and creatinine covariates diminished tHcy as a predictor (p = .084), though the model was still stronger than without this factor (C = .78 and R = 31). tHcy did not significantly interact with APOE?4, as has previously been reported. Neither B12 nor creatinine was similarly effective as a predictor. These results suggest that commonly investigated blood serum biomarkers are at best weakly associated with predicting age- and dementia-related cognitive decline in healthy, asymptomatic elders. fMRI and APOE?4 presently provided the best predictive model

The influence of social support on academic performance: The mediating role of cognitive engagement

Academic performance, which measures a student’s success in learning, is influenced by various factors. One of the most important determinants of academic performance is social support. Parents, teachers, and friends all play a critical role in providing the necessary support that affects students’ cognitive engagement. Therefore, this study aimed to determine the relationship between social support and academic performance, which could be directly or indirectly mediated by cognitive engagement. The subjects used were 228 high school students in 11th grade, aged 15-18. Data were measured using Academic Performance Rating Scale (APRS), Child and Adolescent Social Support Scale (CASS), and Students Engagement Scale (SES) with Cronbach’s alpha values of 0.84, 0.93, and 0.88, respectively. The mediation analysis was conducted using the PROCESS model 4 developed by Hayes. The results showed that the relationship between social support and academic performance occurred through the mediation of cognitive engagement (� = 0.16), with no direct correlation (� = 0.12, p = 0.350). Specifically, more excellent social support was associated with increased cognitive engagement (� = 0.50, p = 0.000), leading to improved academic performance (� = 0.32, p = 0.005). Therefore, it was confirmed that social support is essential to students’ cognitive engagement and academic performance
