WGU D664 Exam Questions & Answers 2026/2027 | 40+ Questions | Child Development, Piaget, Erikson, Neuroplasticity, Cognition & Learning Science | Western Governors University

This WGU D664 2026/2027 Exam Questions and Answers study resource contains 40+ questions, answers, definitions, and detailed review concepts across 16 pages, covering child development, sensory exploration, cognitive development, psychosocial development, Piaget’s stages, Erikson’s stages, neurodevelopment, brain structures, cognition, neuroplasticity, neurodiversity, cognitive styles, differentiated instruction, social-emotional learning, information processing, embodied cognition, cramming, and multitasking. The material connects developmental psychology and neuroscience with classroom learning, helping students understand how cognitive, social, emotional, neurological, and developmental factors can influence education. The opening section focuses on early childhood development and sensory exploration. Sensory exploration is presented as engaging touch, sight, hearing, smell, and taste to help children understand their environment. The document introduces object permanence as understanding that an object continues to exist even when it cannot be seen or heard and associates its development with Piaget's sensorimotor period. It also describes the cognitive transition from sensorimotor to preoperational thought through mastery of object permanence, increasing recognition of the child as separate from the environment, and awareness that personal actions can affect surrounding people and objects. A substantial portion reviews Erikson's psychosocial development theory. The document organizes development into trust versus mistrust from birth to 12 months, autonomy versus shame and doubt from ages 1–3, initiative versus guilt from ages 3–6, industry versus inferiority from ages 6–12, and identity versus role confusion from ages 12–19. The notes connect each stage with educationally relevant developmental needs: infants require consistent care and safety, young children seek independence, preschoolers explore and try new activities, school-age children benefit from positive reinforcement, and adolescents develop a stronger sense of personal and social identity. The autonomy and initiative material gives particular attention to how adults respond to children's developing independence. According to the document, supporting children without excessive control or criticism encourages accomplishment and responsibility. Around age three, the transition toward initiative is characterized by a stronger desire to influence the environment and increased social, physical, and cognitive exploration. These concepts link psychosocial development directly with educational practices that provide developmentally appropriate opportunities for independence. The guide also provides a structured review of Piaget's cognitive-development stages. The sensorimotor stage from birth to age 2 emphasizes learning through movement and sensory experiences such as sucking, grabbing, looking, listening, and crawling. The preoperational stage from ages 2–7 introduces symbolic thought, pretend play, language development, egocentrism, and centration. The concrete operational stage from ages 7–11 emphasizes logical thinking through concrete experiences, including seriation, sorting, classification, mental reversibility, and conservation. From approximately age 12 onward, formal operational thought introduces abstract reasoning, critical thinking, hypothesis formation, prediction, metaphors, mental manipulation, and systematic problem-solving. Another major section examines cognition and neurodevelopment. Cognition is defined in the document as the mental processes involved in acquiring, processing, storing, understanding, and applying information, including remembering, problem-solving, and decision-making. Neurodevelopment is described as the way the brain grows and changes and as an important contributor to acquiring knowledge, strengthening cognitive abilities, and adapting to the demands of formal education. The resource then connects specific brain structures with learning and behavior. The brainstem is associated with essential functions such as breathing and heart rate; the limbic system with emotions and memory; the cerebrum with higher cognitive functions such as language, reasoning, thinking, and problem-solving; and the cerebellum with balance, coordination, and motor skills. The prefrontal cortex receives particular attention for its role in decision-making, impulse control, emotional regulation, planning, organization, and prioritization. The source notes that its continued maturation through the school years can influence academic performance and social interaction. The learning-science portion challenges what the document calls the “myth of normal.” Rather than assuming that all learners should display a single standard pattern of cognitive functioning, the material emphasizes variation in strengths and weaknesses influenced by genetics, environment, and life experiences. It connects this perspective with educational approaches that recognize individual differences and create more inclusive learning environments. Differentiated instruction is consequently described as adapting teaching to students' individual needs, interests, and readiness levels. A closely related section examines neuroplasticity, neurodiversity, and cognitive styles. Neuroplasticity is defined as the brain's ability to adapt and reorganize in response to experience, learning, and environmental change, including the formation and modification of neural connections. The document connects neuroplasticity with instructional strategies, feedback, metacognition, and enriched learning environments. Neurodiversity is described as recognizing natural variation in neurological and cognitive functioning, with autism, ADHD, and dyslexia included among the examples given. Cognitive style refers to relatively consistent approaches to thinking, perception, memory, and problem-solving. The resource additionally reviews social and emotional learning (SEL) and cognitive flexibility. SEL is presented as developing skills and competencies students can use to navigate life's complexities. The discussion of cognitive rigidity challenges the assumption that cognitive abilities inevitably become fixed with age, complementing the document's broader emphasis on neuroplasticity and continued capacity for learning and adaptation. The later pages examine the brain-computer analogy and information-processing theory. Information processing is organized around encoding, storage, and retrieval, with concepts such as sensory input, working memory, and long-term memory. However, the document cautions against interpreting the brain too literally as a computer because this can overlook the influence of emotions, experiences, neural connections, and interactions between brain and body. The related concept of the embodied mind emphasizes that cognition emerges through interactions among the brain, body, experiences, and surrounding environment. The final section addresses the myths of cramming and multitasking. The source associates cramming with mental fatigue, stress, difficulty maintaining attention, reduced recall, and impaired decision-making. Multitasking is described as rapid switching between tasks rather than simultaneously focusing effectively on several tasks, with potential consequences for efficiency, errors, attention, and memory retention. The document's learning-science recommendation is to prioritize activities, concentrate on one task at a time, and allocate dedicated time to individual tasks. Relevant students: This resource is particularly relevant for WGU D664 students, Western Governors University students, WGU Teachers College students, teacher-education students, pre-service teachers, educational psychology students, child-development students, learning-science students, elementary education students, special education students, and educators studying cognitive and neurological development. It is especially useful for students preparing to differentiate Piaget and Erikson stages, identify age-specific developmental characteristics, connect brain structures with learning, explain neuroplasticity and neurodiversity, and apply learning-science concepts to classroom instruction. Referenced academic sources: Piaget, J. The Origins of Intelligence in Children. International Universities Press; Erikson, E. H. Childhood and Society. W. W. Norton & Company. These foundational developmental-psychology works are relevant to the document's coverage of cognitive-development stages and psychosocial development. The uploaded resource itself also explicitly attributes several explanations concerning brain structures, learning science, neuroplasticity, and cognitive variation to WGU.
