What mediates the impact of response alternatives on frequency reports of mundane behaviors?

Conducted 3 experiments using 372 undergraduates' reports of mundane behaviors, namely watching TV and drinking beer, to differentiate between the frame of reference and the self-presentation hypothesis. Results favor the frame of reference hypothesis, suggesting that the impact of response alternatives is more pronounced the less episodic information about the behavior is accessible in memory. Proxy-reports were more affected by the range of response alternatives than self-reports (Exps 1 and 2), and Ss with dispositionally low access to self-related information were more affected than Ss with dispositionally high access to self-related information (Exp 3).
