August 16, 1999SMPC Conference '993 Film Music Literature past studies deal almost exclusively with the referential aspect of musical sound –“cognitive congruency” (Marshall & Cohen, 1988) –selected others: Tannenbaum (1956), Thayer & Levenson (1984) –special issue of Psychomusicology (vol. 13, 1994) vs. accent structure alignment –i.e., how often important events in the music coincide with important events in the visual scene

August 16, 1999SMPC Conference '996 Subject Responses … two VAME ratings synchronization: “… how often important events in the music coincide with important events in the visual scene” effectiveness: “… simply concerns [the observer’s] subjective evaluation of how well the two go together”

August 16, 1999SMPC Conference '998 Problems with Dissonant Stimuli Solution Found

August 16, 1999SMPC Conference '999 Revised Stimulus Preparation A-V alignment conditions were created using Media 100 software on a Macintosh G3 computer sound files were manipulated in Sonic Foundry’s Sound Forge 4.0, using the Time Compress/Expand Sonic Foundry plug-in completed A-V composites were recorded directly from Media 100 onto VHS tape

August 16, 1999SMPC Conference '9910 Consonant Alignment Condition aligned as intended by the composer (visual & music only)

August 16, 1999SMPC Conference '9911 Out-of-phase Alignment Condition alignment conditions based on Preliminary Study

August 16, 1999SMPC Conference '9912 Dissonant Alignment Conditions audio tracks for the McLaren animations were “time expanded” by 115% audio tracks for the “Obsession” excerpts were “time expanded” by 110% –since these excerpts were longer, the gradual misalignment could occur at a slower pace

August 16, 1999SMPC Conference '9913 Subject Info & Method N = 135 UTSA students taking music classes –musical training n (high = 17, mod = 31, low = 87) –gender n (female = 82, male = 53) –stimuli presented to groups of subjects stimuli were presented to subjects using a Samsung VR 5855 video cassette recorder and a ProScan PS ” big screen television –VAME ratings were provided on a continuous line response anchored by either “not synchronized - synchronized” or “ineffective - effective” –each subject was assigned to one of three random stimulus presentation orders –response forms were generated so that order of VAME responses was also randomized into three versions not synchronizedsynchronized

August 16, 1999SMPC Conference '9915 Statistical Analysis - Between (SPSS’s “General Linear Model - Repeated Measures”) repeated measures, fully-factorial ANOVA –three repeated measures: 2 VAME ratings x 6 AV combinations x 3 alignment conditions Tests of Between-Subjects Effects –no significant between-groups variation musical training: p = 0.090; f (2,129) = gender: p = 0.549; f (1, 129) = –interaction between AV combination & musical training is not statistically significant p = 0.622; f (2,129) = 0.477

August 16, 1999SMPC Conference '9916 Statistical Analysis - Within (SPSS’s “General Linear Model - Repeated Measures”) Tests of Within-Subjects Effects –within-groups, ratings were significantly different depending upon the AV combinations p <.0005; f (5) = 20.5 –within-groups, ratings were significantly different depending upon the alignment condition p <.0005; f (2) = Within-Subjects Interaction Effects –alignment condition x VAME p <.0005; f (2) = –AV combination x alignment condition p <.0005; f (10) =

August 16, 1999SMPC Conference '9917 Statistical Analysis - Within (SPSS’s “General Linear Model - Repeated Measures”) Within-Subjects Effects - complex interactions –AV combination x VAME x musical training p =.006; f (10) = –AV combination x alignment condition x VAME p <.0005; f (10) = 3.885

August 16, 1999SMPC Conference '9921 Conclusions accent structure alignment does, in fact, play an important role in subject ratings of both “synchronization” and “effectiveness” –ANOVA & Pearson correlation coefficient based on the results of the present & previous investigations, there appears to be a dynamic relationship between the “association judgment” and “accent structure alignment” aspects of the model of Film Music Perception Revised Model
