Analyzing Individual Differences Statements

The question asks to identify the statement that is NOT correct regarding individual differences. Let's analyze each option:

• Option 1: Individual differences exist in both cognitive and psychomotor domains. This statement is correct. People vary in their thinking abilities (cognitive) and physical skills (psychomotor).
• Option 2: Species characteristics influence individual differences. This statement is correct. Genetic makeup and inherent biological traits (species characteristics) contribute significantly to individual variations.
• Option 3: The cause of individual differences is the social environment, not the physical environment. This statement is incorrect. Individual differences result from a complex interaction of multiple factors, including genetics, the physical environment (climate, geography, etc.), and the social environment (culture, upbringing, education, etc.). Attributing the cause solely to the social environment while excluding the physical environment is inaccurate.
• Option 4: Age also has an effect on individual differences. This statement is correct. As individuals age, their abilities, experiences, and characteristics change, leading to differences across age groups and even within them.

Therefore, the incorrect statement is the one that wrongly limits the causes of individual differences.

Incorrect Statement Identification

The statement "The cause of individual differences is the social environment, not the physical environment" is factually incorrect because both the physical and social environments, alongside genetic factors, are established contributors to individual variations.
