Data on problem solving collected within the framework of Eckblad's (198lb) cognitive theory of affect are analyzed with three-mode principal component analysis. Eckblad's theory contends that affect is mediated by cognitive schemes. When schemes are inadequate for input assimilation, the resistances call forth affects with respect to the events. In this study, the task information load was var...

Principal component analysis has been widely adopted to reduce the dimension of data while preserving information. The quantum version PCA (qPCA) can be used analyze an unknown low-rank density matrix by rapidly revealing principal components it, i.e. eigenvectors with largest eigenvalues. However, due substantial resource requirement, its experimental implementation remains challenging. Here, ...
