Abstract
AbstractBackgroundJudgment is an aspect of executive functioning that is critical to many aspects of daily functioning, and often affected in older adults with cognitive decline. The Test of Practical Judgement (TOP‐J) evaluates judgment related real‐world issues that may arise in aging populations. The current study investigates the incremental validity of the TOP‐J—i.e., the degree to which the TOP‐J adds unique and meaningful information to a clinical assessment beyond other executive functioning tests which are often used as proxies for judgment.MethodsParticipants (N = 97, Mage = 74.73; 74.2%female) who were classified as cognitively unimpaired (CU), subjective cognitive decline (SCD), or mild cognitive impairment (MCI) completed comprehensive neuropsychological evaluation, which included the Wisconsin Card Sorting Test (64‐card version) and Delis‐Kaplan Executive Function System tests of Verbal Fluency and Trail Making Test, Condition 4. Incremental validity was assessed through hierarchical linear regression analysis and was measured by the addition of the TOP‐J (Forms A, B, a composite of A + B), above these widely used executive functioning tests, with clinical diagnosis (CU, SCD and MCI) as the outcome.ResultsThe addition of the TOP‐J A was statistically significant (R2 = .299, F(1,90) = 3.95, p = 0.05) and added incremental validity to predict diagnosis (∆R2 = .031, p = 0.05). The addition of the TOP‐J forms A + B composite also was significant (R2 = .307, F(1,90) = 4.99, p = 0.03, and added incremental validity(∆R2 = .038, p = 0.03), while the TOP‐J B trended toward significance (∆R2 = .024, p = 0.08).ConclusionOur results suggest that including the TOP‐J within neuropsychological evaluations of older adults can enhance diagnostic accuracy and provide clinically valuable information beyond what is derived from traditional executive functioning tests. Considering potential adverse impacts of impaired judgement abilities in the context of neurodegenerative disease, it is of utmost importance to improve the detection of diminished practical judgment skills to increase the protection of vulnerable populations and to prevent potential financial, social, and other areas of exploitation that may occur.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
