A list of some of the Persuasion techniques.

• Authority. Use your authority and others will obey.

• Contrast. We notice and decide by difference between two things, not absolutes.

• Framing. Our perception is influenced by the information we are presented.

• Limited Duration. Given a choice between action and inaction, a limited time to respond increases the likelihood that people will participate.

• Scarcity. I want now what I may not be able to get in the future.

• Social Proof. When uncertain we take cues from other people.

• Trigger. We need small nudges placed on our regular paths to remind and motivate us to take action.

The following summary describes some of the Emotion principles. • Aesthetic usability.

Aesthetically pleasing designs are often perceived to be easier to use.

• Behavioural processing. We respond favourably to learned, expected behaviours.

• Delight. We remember and respond favourably to small, unexpected and playful pleasures.

• Goal setting. We are compelled to strive to achieve a goal if it is achievable.

• Knowledge of results. We continue our actions if we are shown evidence of their success.

• Optimal level of challenge. We like to be challenged and tested, but not too much.

• Social contagion. Our emotions are affected by the actions of those we see around us.

Trust is influenced by a combination of factors which act as Trust Markers.

• Design quality. We perceive value in the things we see.

• Current content. Up-to-date content indicates freshness and responsiveness.

• Extensive quality content. We trust an authority that is plentiful with knowledgeable.

• Affiliation. We judge other based on their recommendations and affiliations.

• Certifications. We trust established, certified organisations and trademarks.

• Testimonials. We trust organisations who trust and value their customers opinions
