Psychological and emotional expression of macroscopic cellpiled structure patterns of wood.

The present study aims to provide a quantitative expression and evaluation of the psychological and emotional variation of macroscopic cellpiled structure patterns of wood, and to establish their positions in sensory, emotional and evaluative dimensions. Based on a Kansei image investigation of the macroscopic structure patterns of 18 species of trees in northeastern China (6 softwood species and 12 hardwood species) and their visual and psychological impact on 50 college students, it uses the semantic differential method of measuring to discover the link between the sensory characteristics of wood patterns and the emotional psychology of the human being. The results show that: 1) the visual sense of most softwood being smooth and soft, it gives the subjects an emotional sense of comfort and joy, and the evaluative dimension is natural and practical; 2) most hardwood being visually rough and hard, it gives an emotional sense of moderate feeling, so the evaluative dimension is natural and decorative; 3) the surface texture of most softwood is smooth compared with hardwood, giving a sense of softness and having an advantage for practical use. In summary, the surface texture of most softwood and hardwood gives a sense of naturalness while most softwood has the advantage of being more practical and most hardwood has that of being more decorative.
