At birth, the number of brain cells (neurons) is largely established and very close to the adult level, though connections continue to form. Brain weight, bone count, and limb length all undergo significant post-natal development.
Psychology is scientifically defined as the study of behavior and mental processes. While it historically involved the soul, consciousness, or mind, the modern definition encompasses observable actions and internal cognitive states.
An emotion is best defined as an excited state triggered by specific stimuli, involving physiological arousal, cognitive appraisal, and behavioral expression. It's more than just a response or irrational behavior, encompassing a complex internal state.
Jean Piaget, a highly influential developmental psychologist, was born in Neuchâtel, Switzerland. His groundbreaking work on cognitive development originated from his Swiss background, not the USA, Italy, or France.
Emotional responses to symbolic stimuli, like flags or specific words, are primarily learned through association and cultural conditioning. Maturation provides the capacity for emotion, but specific symbolic associations are acquired, not innate.
Educational psychology primarily addresses practical issues faced by classroom teachers, such as learning difficulties and motivation, to improve teaching and learning processes. Other options represent broader or less direct applications of the field.
The first emotional expression in infants is typically general excitement, a diffuse state of arousal. More specific emotions like fear, delight, or anger differentiate from this general state as the infant develops.
Motivation is the internal state that drives a person to act, stemming from an internal need. Thinking, perception, and learning are cognitive processes or outcomes, not the initial force compelling action.
Fear is the primary emotion that directly causes the greatest degree of insecurity, as it involves perceived threats and vulnerability. Affection, anger, and hatred are emotions that can arise from or contribute to insecurity, but fear is the fundamental root.
An intelligence test measures a person's mental age, indicating their intellectual development compared to others. Chronological age is actual age, while mature and physical are not standard terms for intelligence test results.
Mildred Parten's research on social play stages (e.g., solitary, parallel, cooperative) is a foundational and widely recognized study in child social development. Bridges, Gesell, and Shirley are known for other significant contributions to developmental psychology.
The Wechsler Adult Intelligence Scale (WAIS), or its variants like VWAIS, is designed for adults and older adolescents, including high school students. Different tests are used for younger children.
The home is the most fundamental agency for a child's initial socialization, emotional development, and learning of basic values and behaviors. School, mosque, and society play important, but secondary, roles in development.
A child's growth and learning are profoundly influenced by both genetic predispositions (heredity) and environmental factors, including upbringing and experiences. Both are crucial for development.
Mental development is fundamentally about learning and adapting, which is best described as the ability to profit from experience. Memorization, social skills, and cell count are related but not the core definition of mental development.
Control is a defining characteristic of the experimental method, allowing researchers to manipulate variables and establish cause-and-effect relationships. Other methods involve less direct control over conditions.
While intelligence encompasses various abilities, intelligence tests often heavily emphasize and are largely synonymous with scholastic aptitude, measuring skills crucial for academic success. Native capacity, reasoning, and emotional control are components but not the sole synonym.
Cognitive development refers to the growth of a child's mental processes, including thinking, reasoning, and problem-solving. Therefore, it broadly deals with the development of the child's mind.
Intelligence tests commonly measure verbal ability, which is a key component of cognitive function and critical for communication and understanding. While mechanical, numerical, and spatial abilities are also aspects, verbal ability is a fundamental and widely assessed dimension.
Identical twins share genetic makeup and similar developmental paths, but their individual experiences and environmental interactions lead to distinct differences in learning. While development, intelligence, and growth are largely similar, learning is highly individualized.
Intelligence tests are primarily designed to measure an individual's academic potential or capacity for learning in a formal educational setting. While related to general aptitude and innate abilities, their practical application often focuses on predicting academic success.
Explanation: The child's IQ is
7
8
×100≈114. In modern Wechsler and Stanford–Binet classifications, this score falls within the High Average range, which is commonly included within the broader Average category. However, some older educational psychology texts classify IQs between 110–119 as Superior. Therefore, the accepted answer may vary depending on the classification table used by the examining authority.
IQ scores tend to remain relatively stable throughout life, meaning the difference between Ahmad's and Akbar's IQs will likely persist. It won't increase, decrease, or disappear, as intelligence is generally consistent over time.
Sigmund Freud's psychoanalytic theory is fundamentally centered on the profound influence of the unconscious mind on human behavior and personality. Options A, B, and D relate to behavioral theories, which are distinct from Freud's psychodynamic perspective.
Mental age indicates a child's intellectual performance compared to the average performance of children at a specific chronological age, reflecting their level of mental maturity. It doesn't measure rate, potential, or general intellectual status.
