Brief Description

The test involves learning a list of 16 items that belong to semantic categories. The items are presented repeatedly, and performance is evaluated through short-delay recall (including perseverations and intrusions) and long-delay recall. It also includes a recognition task, where words from the list must be identified among semantically related and unrelated options. The tool is based on the structure of the California Verbal Learning Test (CVLT), but differs in that it provides three equivalent versions for repeated use with the same participant or within short intervals.

Purpose

The purpose of the test is to assess verbal memory and learning curves, particularly in populations where it is important to evaluate processing strategies, storage, and retrieval of verbal information. It is used to capture an individual’s ability to memorize semantically-based content.

Scoring Method

Performance is evaluated in terms of learning curve, recall and recognition accuracy, the number of perseverations and intrusions, and the use of conceptual strategies during recall. The test allows both quantitative analysis (number of correct responses) and qualitative analysis (type of strategy used, error patterns, etc.).

Validity

The test is currently under development with regard to complete psychometric validation. However, it is grounded in internationally established methodologies such as the CVLT. The inclusion of multiple alternate forms is designed to enhance repeatability validity.

Reliability

Official reliability metrics for this specific form have not yet been published, but the existence of three parallel test versions suggests strong design intent for high test–retest reliability and administration consistency.

Data Analysis and Use

The test can be used in both clinical and research settings for the assessment of memory disorders, verbal learning ability, and processing strategies. It is particularly suitable for populations with neuropsychological impairments or for tracking cognitive changes in intervention programs.
