: exhibiting or typifying personality traits (such as frugality and obstinacy) held to be psychological consequences of toilet training
Overextending psychic energy during the process of toilet training by holding back can result in fixating at the anal stage, creating an anal retentive personality as an adult. The anal retentive personality is characterized by the tendency to cope with conflicts later in life by demonstrating an extreme sense of cleanliness and orderliness, such as dusting furniture or waxing the car when troubled. Bernardo J. Carducci
