In this question, we’re applying Thomas and Chess’s temperament dimensions to classify an infant based on observable patterns of behavior.
Option 1: 'Mixed temperament' — This would suggest a blend of traits across the dimension, with no single dominant pattern. The vignette emphasizes persistent fussiness, irregular sleep, and avoidance of novelty, which aligns more clearly with a single, identifiable pattern rather than a mixed profile.
Option 2: 'Difficult temperament' — This choice describes infants who are highly irregular in routines, have intense reactions to new people and situations, and show negative mood or withdrawal to novelty. The described fussiness, irregular sleep, and negative responses to new toys and people fit this classical pattern of heightened reactivity and lower adaptability.
Option 3: 'Slow-to-warm temperament' — This pattern refers to infants who are more cautious or wary of novelty, but with a gradual approach, typically showing milder reactivity and slower adaptation. The strong fussiness and negative reactions to new stimuli in the vignette point away from the slow-to-warm profile, which would be characterized by initial withdrawal rather than persistent negativity.
Option 4: 'Easy temperament' — Easy infants are typically regular, adaptable, with positive mood and quick adaptation to new experiences. The infant in the scenario exhibits irregular sleep and negative reactions to novelty, which contradicts the easy temperament profile.
Overall, the behavioral cues described—high irritability, irregular routines, and negative responses to unfamiliar people and objects—most consistently map onto the 'Difficult temperament' category, reflecting high reactivity and low adaptability.
