In all societies studied, the most common attachment quality is the __________ pattern.

Correct Answer: D

Rationale: The correct answer is D, 'secure.' Research shows that the secure attachment pattern is the most common across various societies. In this pattern, children feel safe, secure, and loved, allowing them to explore the world and seek comfort from their caregivers when needed. Choices A, B, and C are incorrect because while these attachment patterns exist, they are not as prevalent or universal as the secure attachment pattern. Insecure-avoidant attachment involves children avoiding or ignoring their caregiver, insecure-resistant attachment consists of ambivalence and mixed emotions towards the caregiver, and disorganized/disoriented attachment is characterized by inconsistent and often chaotic behaviors towards the caregiver.

Correct Answer: C

Rationale: Vision is the least-developed sense in newborn babies. While newborns can see, their vision is not as developed as their other senses at birth. Taste, sound, and touch are more developed senses in newborns compared to vision. Over time, through visual stimulation and experiences, a baby's vision gradually improves and develops.

Correct Answer: C

Rationale: In middle childhood, self-esteem becomes more differentiated and organized into a hierarchy based on various domains of competence. This period marks a time when children start to compare their abilities in different areas, such as academic performance, social skills, and physical abilities. Toddlerhood and preschool years are characterized by the development of basic self-awareness and self-concept, but self-esteem hierarchy typically emerges later in middle childhood and further solidifies in adolescence as individuals navigate complex social dynamics and personal identities.

Correct Answer: B

Rationale: Correct answer: School-age children master concrete operational tasks gradually, in a continuum of acquisition. Piaget's theory suggests that children develop cognitive abilities in stages, with concrete operational tasks being acquired gradually as part of this process. Choices A, C, and D are incorrect because concrete operational tasks are not typically mastered all at once, much later than Piaget believed, or necessarily after mastering abstract thinking.

Correct Answer: C

Rationale: Spatial skills develop gradually over childhood and adolescence, reflecting the increasing complexity of these abilities. Choice A is incorrect because spatial skills do not increase exponentially in early childhood but rather develop steadily. Choice B is incorrect as spatial skills are not directly linked to executive function. Choice D is incorrect because spatial skills are not typically housed in a specific hemisphere but involve a network of brain regions.
