Hayashi：Development and Testing of a New Indirect Attitude Measure for Pictorial Objects11ing filler pictures between groups had no effect onattitudescores.A significant main effect oforiginalvalenceoftarget picturewas found (F(2,96)＝33.75,p＜.001,η?＝.27).Multiple comparison using Ryan’smethod revealed that there were significant differencesbetween all comparablepairsofthreeattitudescores.In order to investigate the split-half reliabilityofthe SECT, 32 trials included in each main blockweredivided evenlyinto two parts,and an adjustedreliabilitycoefficient was calculated as in thepreviousexperiment. Results revealed that the SECT inExperiment 2 showed nearly identical reliability(ρ＝.65)to the previous experiment.Figure 3 shows a scatter diagram depicting attitudescoresfrom theSECT and pleasantnessratingsfor participants in Experiment 2. A simple linearregression analysis with attitude scores from theSECT as theindependent variablerevealed that thedependent variable was significantly predicted bySECT attitude scores (F(1, 148)＝51.51, p＜.001,η?＝.26;R ??? ?＝.25).Finally, participants’pleasantness ratings wereanalyzed to investigate whether the emotionalvalence of the filler pictures used in the presentexperiment was almost equal between the twogroups.Table6shows averagepleasantness ratingsfor each target and filler picture used in theexperiment.For each participant, the mean rating scorefor the two positive filler pictures and the meanrating scorefor thetwonegativefillerpictureswerecalculated.

Resultsrevealed that the main effect of the valence of thefiller pictures was significant (F(1,48)＝164,20,p＜.001,η?＝.70). However, there was no significantmain effect ofgroup or interaction effect (F(1,48)＝.01, n.s,η?＝.00; F(1, 48)＝.76, n.s,η?＝.00). Theseresults show that the emotional valence of fillerpictures did not differ between the two blocks,despite those pictures differing between blocks.DiscussionParticipants in Groups A and B completed theSECT with different filler pictures between groups,whereas the target pictures were fixed betweenFigure 3.
