Motor-Free Visual Perception Test-4 (MVPT-4) - MVPT-4：無動作視覺知覺測驗第四版

Description

The MVPT-4 is the most recent revision of the only non-motor visual perceptual assessment that can be used throughout the lifespan. The MVPT-4 provides a quick, reliable, and valid measure of overall visual perceptual ability in children and adults. The MVPT-4 includes 45 items from the MVPT-3 which have been reorganized and grouped for easier administration.

Stimuli are comprised of black-and-white line drawings and designs, with answer choices presented in an easy to record multiple-choice format. No motor involvement is needed to make a response, making the test particularly useful with those who may have motor disabilities. The MVPT is one of the most widely used visual perceptual assessments used by occupational therapists and driver rehabilitation specialists.

The MVPT-4 is designed to be used for screening and research purposes by psychologists, occupational therapists, educational specialists, optometrists, and others who may need to determine a person's overall ability to discern and understand visual stimuli.

Visual Perceptual Abilities Assessed

The following tasks are assessed:

• Visual Discrimination - the ability to discriminate dominant features of different objects, including the ability to discriminate position, shapes, and forms
• Spatial Relationships - the ability to perceive the positions of objects in relation to oneself and to other objects. Items assess the perception of pictures, figures, or patterns that are disoriented in relation to each other, such as figure reversals and rotations
• Visual Memory - the ability to recognize a previously presented stimulus item after a brief interval
• Figure-Ground - the ability to distinguish an object from background or surrounding objects

Visual Closure - the ability to perceive a whole figure when only fragments are presented

The MVPT-4 includes new norms for ages 4-0 through 80+ years. Data was collected from 2012-2014 on a national, stratified sample of more than 2700 individuals. Results of reliability and validity studies are provided, as well as performance comparisons with clinical populations.

Administration and Scoring

The MVPT-4 takes approximately 20-25 minutes to administer. Test plates are contained in one easy-to use book with an easel back. Test administration cues are provided in the test plates to facilitate administration. Scoring is extremely easy; no basals or ceilings are needed. The raw score is quickly converted to ONE overall standard score and percentile rank.

NOTICE: MVPT-3 Record Forms (8289-0) are discontinued and no longer available.

產品簡介

MVPT-4（Motor-Free Visual Perception Test–Fourth Edition）是目前最新版的無動作視覺知覺評估工具，也是唯一可適用於整個生命週期的非動作性視覺知覺測驗。MVPT-4 能夠快速、可靠且有效地評估兒童及成人的整體視覺知覺能力。

MVPT-4 保留了 MVPT-3 的 45 個測驗題目，並重新編排及分組，以提升施測便利性。

測驗刺激材料由黑白線條圖及圖案組成，答案以易於記錄的多項選擇題形式呈現。受測者無需進行任何動作反應，因此特別適用於具有動作障礙的人士。

MVPT 是職業治療師及駕駛復康專家最廣泛使用的視覺知覺評估工具之一。

MVPT-4 適用於心理學家、職業治療師、教育專業人員、視光師及其他需要評估個體整體視覺刺激辨識與理解能力的專業人士，可用作篩查及研究用途。

評估的視覺知覺能力

測驗涵蓋以下能力：

• 視覺辨識能力（Visual Discrimination）
  辨別不同物件主要特徵的能力，包括辨識位置、形狀及外觀的能力。
• 空間關係能力（Spatial Relationships）
  感知物件相對於自身及其他物件位置的能力。題目評估對方向不同的圖片、圖形或圖案的辨識能力，例如圖形反轉及旋轉。
• 視覺記憶（Visual Memory）
  在短暫時間間隔後辨認先前呈現刺激項目的能力。
• 圖地辨識能力（Figure-Ground）
  從背景或周圍物件中辨識目標物件的能力。
• 視覺閉合能力（Visual Closure）
  在僅呈現部分圖形資訊時辨識完整圖形的能力。

MVPT-4 提供適用於 4 歲至 80 歲以上人士的最新常模資料。常模資料於 2012 至 2014 年期間蒐集，樣本超過 2,700 人，採用全國分層抽樣方式建立。

測驗手冊提供信度及效度研究結果，以及與臨床族群的表現比較資料。

施測與計分

MVPT-4 施測時間約為 20 至 25 分鐘。

測驗圖版整合於一本附有展示架設計的測驗冊內，方便施測使用。測驗圖版中提供施測提示，以協助施測流程進行。

計分方式簡單，無需設定基線（Basal）或天花板分數（Ceiling）。原始分數可快速轉換為：

• 整體標準分數（Standard Score）
• 百分等級（Percentile Rank）
