Once you have typed a sample correctly, you can use SALT software to learn about the child’s speech and language skills. The goal of this lab is to introduce you to a number of pieces of information that SALT can give you. You already know how to check a file using the CHECK menu. Many of you also have become familiar with the ANALYZE menu. In this lab, you are going to learn more about the options available in the ANALYZE menu. We will also learn how to read information in the PROFILE menu. The PROFILE menu has information from other children who have been tested and are shown to have normal speech and language skills. This information is our normative database . When we assess a new child, we compare his/her scores to those in the normative database. This is one of the reasons why you need to know the age of the child you are evaluating; you compare your new child to children who are the same age. If your child’s scores are at or below -1.0 standard deviation (SD) of the normative average (mean), we consider the child to be performing below age-expectations. In the real world, professionals sometimes use the criteria of -2.0 SD or -1.5 SD. For class, we will use -1.0 SD as our cut-off. If scores fall above the mean or below the mean but not as low as -1.0 SD, we will consider the child’s ability for that measure as normal. We will use the sample child ‘Jeremy’ to practice and learn about the concepts described below. To open ‘Jeremy’ go to the FILE menu click on OPEN, then open SAMPLE TRANSCRIPTS and then ANALYSIS PRACTICE, and select ‘Jeremy 3-3 CON’. Scroll down the sample. You will notice slash marks in some of the words. For example, one of the first utterances is: C rain/3s The slashes tell the computer that the child produced a morphological inflection. We will learn how to put these slashes in next week. Now select the ANALYZE menu . There are six pieces of information we want you to be able to identify using the STANDARD MEASURES page and/or the TRANSCRIPT SUMMARY page. These are Jeremy’s 1) total utterances , 2) intelligibility , 3) TTR , 4) number of different words , 5) total number of words , and 6) MLU . A description of each is presented below, along with the directions for obtaining the information using SALT. 1. Total Number of Utterances in Sample We have already discussed this index. To find this information, open ‘Jeremy 3-3 CON’ and select from the ANALYZE menu, STANDARD MEASURES and/or TRANSCRIPT SUMMARY. Find the total number of utterances for the child. Jeremy produced 69 total utterances. However, for all analysis with SALT, the numbers are from the Analysis Set, not the Total Utterances (i.e., the complete and intelligible utterances only–all abandon and interrupted utterances are excluded). 1
