Critique Methods

Write a lab report including Introduction and Methods sections, as well as a Critique of the methods, for Experiment B. Assume that the audience for your lab report is a peer –someone who might need to explain or replicate the experiment, but who might not be familiar with all the terminology involved yet. You may write the report in first person (pretending that you were the one who did the experiment) or in third person (reporting on another experimenter who did the experiment). •Your Introduction section should include an explanation of the purpose of the experiment described. What did the experimenters hope to learn? •Your Methods section should include (1) definitions of some terms with which your reader might not be familiar, and (2) a brief explanation of experimental details. Do not simply copy the purpose, definitions, or procedures from your assignment. Try to explain things in your own words. •Your Critiquesection should address any problems either with the amount of information you received, or the procedures described. For example, did the author omit any important experimental details from the description of the methods? Were experimental variables controlled sufficiently? Experiment B: Purpose: The purpose of the experiment was to compare performance -intensity functions for spondaic words and phonetically-balanced lists of monosyllabic words. Definitions of terms: 1. Performance - intensity function: A function that displays how percent- correct scores (on the ordinate) change with changes in intensity (on the abscissa) of a message. 2. Spondaic words (aka spondees): Two-syllable words spoken with equal stress on the two syllables (e.g. hotdog, baseball, toothbrush, etc.). The list used in this experiment was called CID W-1 and contained 36 spondaic words. 3. Phonetically - balanced lists of monosyllabic words : Lists of words of one syllable each (e.g. cow, egg, dog, etc.). Each list usually contains 50 words, and all phonemes (speech sounds) in the language appear in the list with a frequency that approximates the frequency with which they are used in the English language; hence, the list is said to be balanced phonetically (or phonemically). The list used in this experiment was called PB- 50. 4. Speech intensity : The level, or intensity, in decibels (dB) at which the speech message is presented to listeners. Experimental details: •Twenty listeners tested –15 female; 5 male •Performance - intensity functions defined for each of two forms of speech materials: spondaic words (CID W -1) and monosyllabic words (PB -50). Six equivalent lists were used for each type of speech material. • Speech materials presented at six speech intensities that ranged from 14 dB SPL to 24 dB SPL in 2 dB intervals. •For both kinds of speech materials, lists were presented in a descending order of intensities (i.e. 24 dB then 22 dB then 20 dB, etc.) •Speech materials pre-recorded on audio tape by a male talker. •Speech materials presented to one ear of each listener via an earphone (Telephonic, TDH-39). •For both spondaic and monosyllabic words, listeners repeated each word aloud. •Half of listeners received spondaic words first, followed by monosyllabic words; the reverse order was used for the other half of listeners.
