Chapter 3

Related Perceptual Skills

Use Book 3, the Perceptual Skills Evaluation (PSE) to identify related perceptual skill deficits. This procedure identifies and improves performance in regularly occurring activities. Isolated practice of perceptual skills, such as closure and constancy, has not shown to improve performance in a generalized context such as reading (Lerner, 2000). Instruction of strategies to overcome perceptual deficits in a specific context does improve performance (Swanson, Hoskyn, & Lee, 1999). Students who use a strategy successfully in one context may generalize its use to similar contexts (Bendor, 2008).

The PSE evaluates specific perceptual skills in three media categories: objects, pictures, and graphic symbols. Use the Perceptual Skills Chart (Table 3.1) as a quick reference to identify specific perceptual skills within the three media categories.

Table 3.1 Perceptual Skills Chart

Objects Pictures Graphic Symbols
  • Identification
    • color, shape, size, and internal detail
  • Visual closure
  • Figure-ground
  • Visual memory
  • Constancy
  • Part/Whole
  • Identification
    • color, shape, size, internal detail, and outline

  • Part/Whole

The media categories are not listed in hierarchical levels of perceptual difficulty. Many children with low vision find objects and pictures more perceptually challenging than graphic symbols. Letters and numbers are more cognitively challenging because they are abstract, but the identification of objects in natural contexts and pictures with multiple elements may be more challenging visually because they require sophisticated levels of interpretation of perceptual factors related to closure, figure-ground, visual memory, constancy, and part/whole. Teachers of students with visual impairments should not assume that because a student reads print efficiently, he is able to organize study materials or understand illustrations in his textbooks.

Once the student completes the PSE, list the related perceptual skill deficits (e.g., visual closure, visual memory) in column 3 of the IG, using the letter “P” (perceptual skill deficit). Then, in column 4 (Intervention) describe specific strategies that you will use to improve visual efficiency. Collaborate with diagnosticians, content mastery teachers, and general and special education teachers to create the interventions.

The sample Intervention Guide (Table 3.2) shows the related perceptual skill deficits for the media/objects affected by poor visual efficiency during each priority activity added to column 3, and the intervention strategies chosen for the media/objects added to column 4.

An image depicts clipart of a hand holding a cutout of a boat, over a book open to a page which shows a clipart of a girl playing with the boat and a ball in a swimming tub.

The cut out window isolates the salient feature.

An image depicts a picture of a boat divided into two equal rectangular puzzle pieces. The second piece of the puzzle is rotated in clockwise direction until the image is complete.

The perceptual abilities of constancy and part/whole relationships are needed for puzzle resolution.
