DTVP-3: Developmental Test of Visual Perception–Third Edition, Complete Kit - 發展性視覺知覺測驗（第三版）完整套件

Expanded age range

Ages: 4-0 through 12-11

Testing Time: 30 minutes

Administration: Individual

The DTVP-3 is the most recent revision of Marianne Frostig's popular Developmental Test of Visual Perception. Of all the tests of visual perception and visual-motor integration, the DTVP-3 is unique in that its scores are reliable at the .80 level or above for all subtests and .90 or above for the composites for all age groups; its scores are validated by many studies; its norms are based on a large (N = 1,035), representative sample; it yields scores for both visual perception (no motor response) and visual-motor integration ability; and it is shown to be unbiased relative to race, gender, and handedness.

New Features of the DTVP-3

• New normative data were collected in 2010 and 2011
• Norms were extended upward to age 12 years, 11 months
• The composite scores have no floor or ceiling effects
• Numerous eligibility and validity studies, including studies of the test's sensitivity, specificity, and ROC/AUC, have been provided
• The study of item bias has been expanded
• The overall look of the test was updated

DTVP-3 Subtests

The DTVP-3 has five subtests.

1. Eye–Hand Coordination. Children are required to draw precise straight or curved lines in accordance with visual boundaries.
2. Copying. Children are shown a simple figure and asked to draw it on a piece of paper. The figure serves as a model for the drawing. Subsequent figures are increasingly complex.
3. Figure-Ground. Children are shown stimulus figures and asked to find as many of the figures as they can on a page where the figures are hidden in a complex, confusing background.
4. Visual Closure. Children are shown a stimulus figure and asked to select the exact figure from a series of figures that have been incompletely drawn. In order to complete the match, children have to mentally supply the missing parts of the figures in the series.
5. Form Constancy. Children are shown a stimulus figure and asked to find it in a series of figures. The targeted figure will have a different size, position, and/or shade, and it may be hidden in a distracting background.

DTVP-3 Composites

The results of the five DTVP-3 subtests are combined to form three composites: Motor-reduced Visual Perception, Visual-Motor Integration, and General Visual Perception (combination of motor-reduced and motor-enhanced subtests). Subtests were assigned to a particular composite on the basis of the amount of motor ability required by their formats.

COMPLETE DTVP-3 KIT INCLUDES: Examiner's Manual, Picture Book, 25 Response Booklets, 25 Examiner Record Booklets, and a Copying Scoring Template, all in a sturdy storage box. (©2014)

DTVP-3（發展性視覺知覺測驗－第三版）是 Marianne Frostig 廣受歡迎的《發展性視覺知覺測驗》最新修訂版本。在所有視覺知覺及視覺－動作整合測驗中，DTVP-3 具有多項獨特優勢：

• 所有分測驗的信度皆達 0.80 或以上，所有綜合指數（Composite Scores）的信度皆達 0.90 或以上，適用於所有年齡層。
• 測驗效度已獲多項研究驗證。
• 常模建立於大型且具代表性的樣本（N = 1,035）。
• 可同時評估純視覺知覺能力（無需動作反應）及視覺－動作整合能力。
• 研究顯示測驗不受種族、性別及慣用手影響，具有良好的公平性。

DTVP-3 新增特色

• 於 2010 年及 2011 年重新蒐集最新常模資料。
• 常模年齡範圍擴展至 12 歲11個月。
• 綜合指數無地板效應（Floor Effect）或天花板效應（Ceiling Effect）。
• 提供多項資格判定與效度研究，包括測驗的敏感度（Sensitivity）、**特異度（Specificity）**及 ROC/AUC 分析。
• 擴充試題偏差（Item Bias）研究。
• 全面更新測驗版面設計，使內容更加清晰易讀。

DTVP-3 分測驗

DTVP-3 包含五項分測驗：

1. 手眼協調（Eye–Hand Coordination）

受測者需依照指定的視覺邊界，精確描繪直線或曲線，以評估手眼協調能力。

2. 圖形臨摹（Copying）

受測者根據提供的圖形範本，在紙上進行臨摹。題目由簡至繁，圖形複雜度逐步提高，以評估視覺－動作整合能力。

3. 圖形背景辨識（Figure-Ground）

受測者需在複雜且干擾性高的背景圖案中，找出指定的目標圖形，以評估圖形與背景辨識能力。

4. 視覺閉合（Visual Closure）

受測者觀看未完整呈現的圖形，並從多個選項中找出完整對應圖形。完成配對時，需在心中補足缺失部分，以評估視覺補全能力。

5. 圖形恆常性（Form Constancy）

受測者需在一系列圖形中辨識指定圖形，即使目標圖形的大小、方向、位置或明暗有所改變，甚至隱藏於干擾背景中，仍須正確辨識。

DTVP-3 綜合指數（Composites）

五項分測驗的結果可組合成三項綜合指數：

• 低動作需求視覺知覺（Motor-reduced Visual Perception）
• 視覺－動作整合（Visual-Motor Integration）
• 整體視覺知覺（General Visual Perception）（結合低動作需求及高動作需求分測驗）

各分測驗依據施測時所需的動作能力程度，歸類至不同的綜合指數，以提供更全面的視覺知覺能力分析。
