خلاصه	The Self-Monitoring Scale, introduced by Mark Snyder in 1974, measures the extent to which people observe and control their expressive behavior and self-presentation in response to situational and interpersonal cues. High self-monitors are sensitive to social context and skilled at adjusting how they come across, behaving like social chameleons whose conduct varies across situations; low self-monitors express their inner attitudes and dispositions more consistently regardless of audience. The original 25-item true/false scale was designed to be internally consistent and temporally stable, validated through laboratory and field studies of expressive control. The construct became influential in person-situation debates, attitude-behavior consistency, and research on impression management, persuasion, and relationships, although the scale's dimensionality and revisions have been the subject of ongoing discussion.	The Need for Cognition Scale (NCS) is an 18-item measure assessing individual differences in the tendency to engage in and enjoy cognitive effort. Developed by John Cacioppo and Richard Petty in 1982, the NCS operationalizes need for cognition as a stable personality trait reflecting preference for thinking about complex problems, enthusiasm for intellectual pursuits, and intrinsic enjoyment of cognitive challenge. A brief 9-item version (NCS-9) is also available. The scale has become standard in psychology research examining motivation for learning, persuasion, decision-making, and academic achievement.
