A synopsis of the hypothesis - Dr Newman

The goal of the slips of the mind lab  was to show that speech errors (overt) and inner slips (of the mind) are both due to planning errors, not articulation problems (tongue twisting).  So, you are actually predicting the same pattern of errors for both conditions, which is a bit of a problem since usually one doesn't predict "no difference" in psychology experiments (it's hard to accept the "null hypothesis").  Therefore, to show that the experiment would have picked up differences, had there been any between inner and overt slips, we included a speech rate manipulation.  There the prediction is straightforward--more errors for both conditions (inner and overt) when the speech rate is made faster, but the overall pattern of errors (rather than the actual number) should remain the same, and equivalent for both groups.  The (3) papers tell you about the planning process, e.g., the hypothesised presence of a monitor (Motley), for example, or a network that produces slips (Dell & Reich), all of which point to planning, not articulation problems, as the sources of slips of the tongue (and mind).  Just view the 3 papers as background reading on the nature of slips of the tongue and some examples of theories to account for them, not as specific to this particular experiment.  Its aims were very simple, just to show that speech errors are really planning errors, not articulation errors.  Finally...  I want you to use the slips you collected to illustrate your discussion of the nature of slips of the tongue when you introduce them in the introduction section, using your examples to define the different types and... ...in the results to illustrate the types of patterns that commonly occur (e.g., more anticipations than perseverations...).  Look at your own data and see how well they match the relative frequencies of occurrence of the different types in the experiment.
