Comparing Angular and Curved Shapes in Terms of Implicit Associations and Approach/Avoidance Responses

Area of Science:

• Cognitive Psychology
• Visual Perception
• Shape Psychology

Background:

• Humans generally prefer smoothly curved shapes over angular ones.
• The psychological underpinnings of this shape preference are not fully understood.
• Previous research suggests potential links to learned associations or innate responses.

Purpose of the Study:

• To investigate the origin of the preference for curved shapes over angular ones.
• To examine semantic associations and approach-avoidance behaviors linked to abstract shapes.
• To differentiate between learned associations and inherent perceptual qualities influencing shape preference.

Main Methods:

• Experiment 1 utilized a multidimensional Implicit Association Test (IAT) to assess associations between shapes (curved/angular) and semantic categories (danger, valence, gender).
• Experiment 2 employed a Stimulus Response Compatibility (SRC) task with a manikin to measure approach-avoidance reactions to curved and angular polygons.
• Implicit measures were used to bypass conscious categorization and tap into automatic responses.

Main Results:

• Curved polygons were implicitly associated with safety, positive valence, and female names.
• Angular polygons were associated with danger, negative valence, and male names.
• Approach-avoidance tasks showed faster and more accurate responses when moving towards curved shapes, suggesting a direct positive response, while angular shapes did not elicit a clear avoidance response.

Conclusions:

• The preference for curvature is not solely explained by the association of angles with threat.
• Smoothly curved contours appear to inherently enhance the pleasantness of abstract shapes.
• Further research is necessary to fully elucidate the mechanisms behind shape preference and its implications.
