Text is limited compared to spoken language. To elaborate on that statement, spoken language has so many more features that can influence conservation such as body language or the volume of voice. Text initially was just characters and words however people have creatively developed ways of proposing what would happen if the conversation was spoken. For example anger can be expressed in words but now is commonly expressed with capitals. “SCREW SCIENCE HOMEWORK” (quote from my facebook thread 🙂 ); this has a mix of aggressive words but the capitalisation of the words make it sound like its been shouted across the page in frustration therefore emphasising anger with just characters.
To test if this theory works;
1. It is going to rain on Sunday.
2. IT IS GOING TO RAIN ON SUNDAY.
These are both the same statements in wording. The imagery of the text itself in statement 1 in comparison to statement 2 has a quite calm, not too bothered sense about it, however statement 2 looks more aggressive and threatening because capitals are not usually used in standard writing. The sense of anger and loudness appears to form around the characters of statement 2 and therefore create a shout. This is a creative solution in text to solve the problem of volume in text.
