Which description best captures multi-sensory defensiveness?

• A. Easily distracted, difficulty taking in new information, reacts constantly to input, emotionally labile, easily upset by seemingly trivial matters
• B. Under-aroused and ignores input
• C. Calm and organized responses to sensations
• D. Seeks intense sensory input

Answer: (A)

Multi-sensory defensiveness occurs when sensory input from many modalities is experienced as aversive and overwhelming, leading to global over-arousal and dysregulation. The description that includes being easily distracted, having difficulty taking in new information, reacting constantly to input, being emotionally labile, and easily upset by seemingly trivial matters fits this pattern because the child is overwhelmed by typical sensory stimuli, which disrupts attention and processing and provokes rapid, fluctuating emotional responses. This reflects poor modulation across multiple senses rather than a deficit in just one area. In contrast, under-aroused and ignoring input points to hypo-responsivity, calm and organized responses suggest effective self-regulation, and seeking intense sensory input describes a different pattern—sensory seeking—rather than defensive over-responsivity.
