Document Summary
Needed 3 large scale factors to understand the intercorrelations. Each factor reflects correlations between specific traits. Went beyond that: understand the physiological underpinnings of these factors. Intensity of stimuli increases = higher arousal response/huge emotional response. Neurotic: prone to anxiety, depression, other strong emotional responses to the world around them. Factor analytic theory factor analysis: conducts mathematical analysis of inter-correlated variables. Measurements: take sample, make correlation (eg. greater heights. How to explain correlations by hypothesizing number of small underlying factors. Factor analysis gives formula for how to understand intercorrelations between number of variables. Reflect an underlying factor/hypothetical construct that relates variables together. Math doesn"t say what factor is, only gives equation. We have to decide what the factor is. Could identify psychodynamic processes, defense mechanisms, depending on data. Results depend on parameters orthogonal: themselves are not correlated with each other non-orthogonal: Appear across cultures: generically true about human beings.
