Quizplus · Accepted Answer

The Behavior Genetics Perspective by Buss and Plomin (1984) identifies three core temperament dimensions: activity level, sociability, and negative emotionality (also known as emotional reactivity or affectivity). These dimensions have been consistently identified across various studies and are believed to have a genetic basis. Sociability refers to the tendency to seek social interaction, while negative emotionality refers to the tendency to experience negative emotions such as fear, anger, and frustration. Therefore, option D is the best answer as it includes all three of these core temperament dimensions. Option A is incorrect because attention orienting, while important, is not considered one of the core temperament dimensions. Option B is incorrect because distractibility is also not considered a core temperament dimension. Option C is incorrect because it includes attention orienting and distractibility, but not sociability or negative emotionality.
