23 scientifically validated cognitive tests covering executive function, processing speed, working memory, episodic memory, fluid intelligence, spatial cognition, verbal ability and metacognition. A standardised cognitive assessment tool for educational research, natively designed in Traditional Chinese.
Illustrative trial · simulated data
UCG is based on classic theories in cognitive psychology and covers eight core cognitive constructs, with each construct containing 1-5 standardised quizzes.
A core ability of cognitive control, including inhibiting irrelevant information, switching flexibly between tasks, and updating working memory contents in real time.
The efficiency of basic cognitive processing and sustained attention is the foundation of other higher-order cognitive functions.
Ability to temporarily store and operate information, covering the two major subsystems of the speech loop and the visuospatial module.
Linked memory for specific learning events is a core construct in learning sciences research such as the testing effect and spacing effect.
Abstract reasoning ability that does not rely on prior knowledge is stably associated with academic achievement and is a core anchor point in cognitive tests.
The ability to process information in mental-spatial operations, including static mental rotation and dynamic multiple-object tracking.
Accumulated language knowledge and reasoning ability, reflecting the crystallisation of long-term learning.
Awareness of and regulation over one's own cognitive processes is a key capability for self-directed learning.
Each Quiz uses cognitive psychology paradigms validated over decades, with a clear research foundation in reliability and validity.
The response time, stimuli and responses for each trial are fully archived, supporting trial-level analysis and mixed-effects models.
Data are stored in de-identified form and do not affect course grades. IRB approval has been obtained, and authorisation may be withdrawn at any time.
The stimulus materials and interface are both natively designed in Traditional Chinese, not translations, making them suitable for Chinese-language users.
