Patient A was correct on 9, patient B was correct on 10, and patient C was correct on 11. A small group of 12 age-matched controls were also tested and obtained the following scores: 17, 17, 16, 16, 15, 15, 15, 13, 12, 12, 10, 9.Write a brief (one-paragraph) description of your analysis and interpretation of these results.(2) A patient with a problem spelling words to dictation was tested on 20 ‘regular’ words (e.g., silt, help) and 20 ‘irregular’ words (e.g., myth, head), matched for word frequency. He was correct on 10 regular and 4 irregular words.(i) Is this difference significant?The two lists of words were also given to 12 age-matched controls, who produced these scores:Regular Irregular18 1718 1616 1616 1715 1315 1415 1214 1114 1013 1012 911 7(ii) Is there a significant difference between the spelling accuracy for regular and irregular words in the controls?(iii) Compare the patient’s performance with that of the controls.(iv) Write a one-paragraph report of your analyses and interpretation of ALL the results in (2).PART 2Refer to the data set attached (and emailed to you as an Excel document).There are 193 pictures of objects (taken from Snodgrass & Vanderwart, 1980), each of which has the following values:• the mean rating of the familiarity of the object depicted by the picture (from a controlgroup of raters, using a 5-point scale, where 5 = very familiar)• a measure of the name agreement (from the same controls), where 100% would bethat all the controls gave the same, target name• the word frequency of the name of the object (taken from Celex and expressed asfrequency per million words)• the number of phonemes in the name of the object• the mean rating of the age-of-acquisition (AoA) of the name of the object (with lowvalues indicating ‘early’-acquired and high values indicating ‘later’-acquired)• an anomic patient’s naming score of these objects. The objects were presented FIVEtimes, and the score is the number of times the patient named each object correctly.(3) Devise a naming test that manipulates age-of-acquisition and controls (or matches) for word frequency and, as much as possible, for other variables. Select 12 “early-acquired” and 12 “late-acquired” items. List your items and complete the following table:Early Late Is the difference significant?Mean AoArange of AoA ratingsMean FrequencyMean FamiliarityMean % name agreementMean number of phonemesMean naming accuracy(4) Analyze the naming performance of the patient on the sub-set of 24 items you have selected for your new test. Is there a significant effect of age-of-acquisition on the patient’s naming performance for this test?(5) Conduct a simultaneous multiple regression analysis of the entire data set, where the naming score is the dependent variable, and the independent (or predictor) variables are: familiarity, name agreement, frequency, word length, and age-of-acquisition.(6) Report your results of the multiple regression analysis (and those in 3 and 4 above) in the form of a Results section of a paper published in the journal Cognitive Neuropsychology, along with a brief theoretical account of the major features of the results.DATA SET:Object name Familiarity %Name Agree Frequency No.Phons AoA Naming scoreanchor 1.73 100 5 4 3.35 2apple 4.48 100 18 3 1.7 3arm 4.73 100 104 2 1.55 3arrow 3.27 90.9 8 3
