[00:00:01.590]Hello, my name is Justin Franzen. I am a member of the vision, attention,
[00:00:06.030]memory, and perception lab here on campus.
[00:00:08.370]I am a sophomore and this is my UCare project on
[00:00:12.930]examining the relationship between music perception and emotion perception
[00:00:19.530]in everyday life.
[00:00:20.550]The ability to discern and react to the emotions that individuals convey is
[00:00:25.260]important across a variety of settings.
[00:00:28.530]One common way of testing this in lab is to ask the participant if a face is
[00:00:32.850]positive or negative,
[00:00:35.760]some facial expressions such as happiness are consistently rated positively
[00:00:40.860]while other facial expressions such as anger are consistently rated negatively.
[00:00:46.320]However,
[00:00:47.220]some facial expressions are ambiguous and are commonly rated either
[00:00:51.480]positively or negatively.
[00:00:53.730]The foremost example of this being surprised surprise
[00:00:58.590]can be interpreted as either positive or negative, depending on the context,
[00:01:02.700]such as if someone was in say it was a
[00:01:07.590]surprise birthday parties, since a surprise would be very positive,
[00:01:11.970]very happy. Whereas if it was,
[00:01:16.620]they just found out they lost $500 or they found out their
[00:01:21.420]friend was in an accident,
[00:01:23.040]it would be a more negative interpretation of surprise.
[00:01:27.180]So it can go either way.
[00:01:28.830]And previous research has also found evidence to support this.
[00:01:33.180]It has been found that presenting an ambiguous face with only images of happy
[00:01:37.560]faces,
[00:01:38.430]the ambiguous faced surprised face is interpreted as more positive.
[00:01:43.260]And when presenting it with only images of angry faces,
[00:01:46.620]it is interpreted as more negative that going on to show that
[00:01:51.840]context dictates how surprised emotion is
[00:01:56.310]interpreted.
[00:01:58.110]Previous research has shown that the Valium subscribed to surprise can be linked
[00:02:02.460]to eye movements and fixations with positive impressions of surprise.
[00:02:06.540]Being linked to the speed at which both the eyes and the mouth are fixated.
[00:02:11.490]It has been demonstrated that participants per perception of surprise can change
[00:02:16.140]as a function of how they orient to an image.
[00:02:18.870]Given the large amount of variability between how individuals perceive surprise
[00:02:23.760]it has become an often used tool to investigate the factors
[00:02:28.530]impacting emotion perception.
[00:02:32.490]I look to determine the degree to which emotion perception may be influenced by
[00:02:37.350]music perception is generally believed that major chords are perceived as
[00:02:41.580]positive and minor codes are perceived as negative.
[00:02:45.090]Although why this occurs is not well understood or well researched.
[00:02:49.740]And it previous eye tracking study from my lab,
[00:02:52.470]it was observed that music pieces written and major chords tended to bias
[00:02:56.040]individuals towards positive stimuli in a free task consisting of a collage of
[00:03:00.910]images, minor chords. On the other hand,
[00:03:03.700]tended to bias individuals towards negative stimuli.
[00:03:07.120]This just means in a task where there were four images present and on the
[00:03:11.680]screen in each corner,
[00:03:14.140]and these images could be either positive or negative,
[00:03:17.380]say a car accident or a puppy or a flower or something,
[00:03:22.330]puppy or flower being positive car accident. Being negative.
[00:03:26.380]People tended to bias towards a positive
[00:03:31.000]image when a major chord was playing.
[00:03:35.230]But when a minor chord was playing, they tended to bias towards negative.
[00:03:39.460]I use this finding to, to influence mine,
[00:03:44.710]the present study capitalizes on this previous finding to examine whether the
[00:03:49.180]simultaneous perception of music during an emotion judgment task influences
[00:03:54.190]the interpretation of surprised faces. Specifically,
[00:03:57.700]I was interested in whether major chords would advise individuals to adopt a
[00:04:01.450]positive impression of surprise faces.
[00:04:04.120]Whereas minor chords would bias individuals to adopt a negative impression of
[00:04:08.110]surprise faces. My task included two tasks,
[00:04:12.940]a baseline task,
[00:04:14.080]and an ambiguous emotion task in the baseline task participants were presented
[00:04:19.060]a face as either angry, happy,
[00:04:21.730]or surprised and asked her a sponsor key press.
[00:04:24.280]If it was positive or negative here on the left is a surprised,
[00:04:29.080]angry, and then a happy face
[00:04:34.150]for the ambiguous emotion task. I created 24 unique
[00:04:40.510]arpeggiated chords that I recorded on guitar.
[00:04:44.770]Each note in the 12 equal temperaments,
[00:04:49.270]some of that we use in Western music was used twice. Each,
[00:04:54.370]each note had both a major and a minor chord associated with it.
[00:04:58.330]I randomly assigned either a 60 beats per minute condition by slow condition
[00:05:03.280]or at 120 beats per minute condition if asked condition
[00:05:08.020]to each no, every,
[00:05:11.590]every chord every year,
[00:05:13.450]arpeggio had a corresponding arpeggio of a different note
[00:05:18.460]that used the same pattern, but of the opposite,
[00:05:24.130]um, modality as either
[00:05:27.790]every major PA every major arpeggio pattern would have a corresponding,
[00:05:33.100]minor arpeggio pattern that used the same beats per minute and the same
[00:05:37.780]pattern just minor instead of my major. And here are two,
[00:05:42.220]here's an example of.
[00:05:49.710]Uh.
[00:05:50.790]That one was major. Now here's the corresponding.
[00:05:56.000][Inaudible].
[00:06:03.670]During the ambiguous emotion task participants were presented a face and were
[00:06:08.260]asked to respond by key press. If it was positive or negative.
[00:06:11.920]While this occurred,
[00:06:12.790]music was played over headphones participants take note as it
[00:06:17.740]was not relevant to their primary task,
[00:06:20.350]faces presenting during the trial were either angry or surprised.
[00:06:25.390]And here is a video of what the trial was.
[00:06:41.950][Inaudible].
[00:06:47.350]So, as you could see in that video,
[00:06:50.950]as you could see in that video, um,
[00:06:54.910]the face and the music were presented at the same time and that the music
[00:06:59.770]kept playing through until they responded this way.
[00:07:02.830]In order to hear that there was enough time to play the music that the music
[00:07:06.880]could form an impression.
[00:07:08.770]If the music was not playing during the results section,
[00:07:12.340]it could potentially be too short to influence perception,
[00:07:19.330]results, and conclusions. Unfortunately,
[00:07:22.390]that's fear has not been good for data collection throughout our lab.
[00:07:25.750]We have found, we have had very few sign-ups.
[00:07:28.570]So our current sample size is too small to analyze in any meaningful way.
[00:07:33.220]Data collection will continue through the end of the term and potentially into
[00:07:37.810]the summer.
[00:07:39.040]The plan for data collection is to compare ratings of surprise on a pre
[00:07:42.820]experimental baseline emotion measure to the re to the ratings
[00:07:47.530]provided to surprise faces.
[00:07:50.710]We will also examine whether music perception influences the ratings of faces
[00:07:55.120]that are more clearly positive or negative.
[00:08:01.180]For example, would participants have less,
[00:08:03.910]a less negative view of a fearful face if presented along with accompanying
[00:08:08.020]music that consists solely of major chords. Lastly,
[00:08:11.350]we'll examine whether I movement patterns change as a function of facial emotion
[00:08:15.910]and music type. Thank you.
