造形複雜度認知與視覺記憶關係之探討

A Study on the Complex Cognition of Shape with Reference to Shape Memory

本研究是從視覺認知的角度對於造形複雜程度與視覺記憶作基礎性的探討。受測者被要求記憶一個刺激造形，並在另外的9個干擾刺激造形中挑選出完全相同的造形出來。在造形複雜程度的評估上，是以觀察者對於刺激造形的記憶結果正確性作分析。從分析探討中得到以下幾項結果：1.隨著基本造形單元個數的增加會讓造形的複雜性增高，造成造形記憶的困難。2.在幾何造形上，受測者於5個單元造形個數內，對於造形的記憶仍未達其能力的臨界值；不規則單元造形個數超過2個以上時，受測者在造形記憶上其困難度顯著升高。3.隨著造形邊數的增加，受測者對於造形記憶會越困難；在具造形組合手法的造形上亦然。4.受測者是否具有造形設計背景並不會顯著影響造形的記憶。5.造形的類型及單元造形個數這兩項因素對於受測者的造形記憶有顯著影響；至於在各因素的交互作用上，只有造形的類型及單元造形個數這兩項的交互作用達顯著標準，其他組合的交互作用則不顯著。不同的造形組合手法對於造形的記憶有顯著影響。

This study is a fundamental approach of shape complexity with regard to shape memory. Participants were asked to recognize and memorize one shape stimulus, then to select the same shape from another nine random shapes. We use subjects' correct answer rate of recognition memory task to evaluate the degree of shape complexity. The results showed that: 1.The shape complexity rose following the increase number of sub-shape that contained in whole shape. 2. For geometric shapes, below five sub shapes, the shape memory tasks still did not reach the threshold of subjects' ability. For irregular shapes, when the shape contain more than two sub shapes, it became difficult to memory the shapes for subjects. 3. Shape complexity rose according to the increase of edge number of whole shape. 4. The design background did not influence the shape memory task significantly. 5. The shape's type and number of sub-shape significantly influence shape memory task. Their interactive effect significantly influence shape memory task too. Other factors and interactions have no significant influence. The shapes with arrange method by rule have significantly influences for shape memory task.
