A high noise environment is exposure operationally to more than seven advertisements in a brief time period. Three groups of subjects were assigned randomly to one of three treatments (23, 25, and 26 subjects); two low noise conditions and one high noise condition. Decline in ad mentions occurred for all ads between the low noise and high noise conditions. The number of thoughts generated and the order of ad mentions varied substantially between ads. The methodology may he useful in learning if the ad for a specific hrand gains processing space in a consumer's mind when the consumer is exposed to several competing ads in brief periods of time. Received November 8, 1984. Accepted for publication March 2, 1984. A study of 1,800 TV commercials showed that only 32 percent of those exposed could even describe, and only 16 percent could remember, the brands that were advertised (5). Consumers have been ©JOURNAL OF ADVERTISING, Vol. 13, No. 2, 1984 found to avoid processing advertising for unknown and nonpreferred brands versus preferred brands (9). Bogart (2) notes, "advertising research data accurately reflect the fact that many messages register negative inapressions or no impressions at all on many of the people who are exposed to the sight or sound of them." Consumer information processing is likely to be limited to handling one to two bits of data per ad in a limited number of ads received in a given setting. One to two bits of information from four or five ads is likely to represent the handbng capacity for most consumers even when exposed to ten or more commercials or print ads. Research findings by Simon (8), Miller (6), Woodside and Sherrill (10), and Jarvis and Wilcox (3) indicate support for the hypothesis that processing capacity varies from four to five chunks of information to as many as seven. An advertisement can be viewed as one chunk of information. Given the limited information processing capacity of consumers and the high noise environments that occur when consumers are exposed to ads (i.e., more than seven ads are seen in a brief time period), one measure of the effectiveness of an ad is whether or not the ad gains some share of the available processing capacity when consumers are being exposed to several ads. This article reports the findings on consumer information processing of print advertisements in low versus high noise conditions; the low noise being exposure to five ads and the high noise condition being exposure to ten ads. The study was designed to answer the following questions: 1. Is the rate of brand name mention for one brand substantially greater than for competing brands in low and high noise conditions? 2. Is the rate of first mention and order of mention for one brand substantially greater than for competing brands in low £ind high noise conditions? 3. Does the rate of brand name mention decline substantially from low to high noise conditions? If so, are the rates of decline different by brand? 4. Does the ad for one brand produce more or less positive, negative, neutral, or total thoughts compared to competing brands? Low and high noise conditions were used in a thought verbalization experiment to answer these questions. METHOD Ten full-page magazine ads were used in the experiment: six travel and four product ads. Descriptions of the ten ads appear in Exhibit 1. The product ads were selected to represent noise for the travel ads. Travel ads often appear near ads for other services and products. Most of the travel ads were chosen to be of relevant interest to the target population sampled, i.e., describing the benefits of visiting a desired vacation destination for young adults. Subjects Seventy-four subjects were used. The subjects were senior university students. Each subject was qualified for participation by affirming prior vacation travel experience. Each subject was approached with the request to participate in "a communication study," as the subject was leaving a classroom. No payment was made for participation. Procedure Each subject was read verbalization instructions before being shown five or ten ads, i.e., a low noise or a high noise treatment. A risk in persuasion research is that subjects may edit some thoughts from their report that intuition tells them do not interest the researchers. When thoughts of this type are of interest, "priming" instructions are sometimes used in which a number of thought categories that should be reported are identified. The intent is to reassure subjects that such thoughts are worth reporting without drawing great attention to them (11:156). The following priming instructions were given to each subject: "Thank you for agreeing to participate in this study of communications. The purpose of the study is to learn a person's thoughts and feelings when remembering reading printed material. After reviewing some printed material, you will be asked to tell someone about the material — what it was about, your thoughts, and your feelings about what you have read. Please tell the person about any thoughts that come to your mind while reading the material. If you had any thoughts of how the material relates to your own life, please tell the person. Please tell the person if any suggestions in the material looked interesting or boring, good or bad, to you. Please tell about any questions that you may have asked yourself while reading, such as 'I wonder what this means?' 'Is this true?' Please say any opinions that you might have had while reading, such as 'I have always wanted to do this.' Or, 'Who cares about this.' Do you have any questions?" These instructions were understood readily by all subjects. The priming instructions suggested both decoding ("Is this true?") and encoding ("I have always wanted to do this.") examples of thought categories. Encoding priming was done to learn if subjects provided "connections" (4) to experiences in their own lives with specific ads. Krugman has suggested that an effective ad message stimulates the consumer to have "bridging" or "connecting" thoughts relating the message or brand to the consumer's personal life. Krugman's premise is that such thinking heightens subsequent message processing activity and the chance that the subject will initiate immediate attitude or preference deliberations. Note that the instructions called for the subject to verbalize thoughts "after reviewing some printed material." An initial test requesting some subjects to verbalize thoughts whUe reading produced so many thoughts and judgments about the quality of the structure of the ads that the procedure was untenable. Requests for thought verbalizations while viewing ads are likely to produce substantial experimenter effects, with subjects no longer decoding or encoding the ads for personal meanings. The five or ten ads were removed from sight after the subject completed reviewing the material. No time limit was placed on the subjects to read the material. This procedure was used since arbitrarily assigned brief limits may exclude valid thoughts that take longer to produce. Also, an important advantage of print versus broadcast advertising is that print viewing is subject controlled while broadcast viewing is not. The "holding power" or impact of an ad can be determined more easily if the subject is permitted to control the pace of processing the ads. After the subject indicated completion of reading the ads, the ads were removed from sight, and another person was requested to enter the room to listen to the verbalized thoughts. Tape recordings were made of the verbalizations. At the same time, the experimenter made written notes of the topics and thoughts made by each subject. Following the verbalization of thoughts on the ads, the subject was taken to another room. Both the subject and the listener were asked what brands and products were described in the material and the purpose of the study. Subjects were informed that the study was on the impact of advertising in the debriefing.

Treatments The first low noise treatment consisted of ads for the Bahamas, Bermuda, Blue Stratos cologne, Colorado, and Maxell recording tapes. Subjects in the second short treatment were shown ads for Blue Stratos cologne, Florida, Maxell tapes. Palm Springs, and Quebec. The ads in the high noise condition included the eight different ads in the two low noise conditions plus two additional ads, one for BVD underwear and one for Camel cigarettes. Ads in each condition were rotated after being viewed by a subject to eliminate order of presentation bias. Twentythree, twenty-five, and twenty-six subjects were exposed to the first low noise, second low noise, and the high noise treatments respectively. ANALYSIS Two judges listened to the tape recordings of ad verbalizations independently of one another and recorded the number of positive, neutral, and negative thoughts mentioned by each subject. Positive thoughts were defined as those in which the subject expressed agreement or was favorably disposed to the ad or its contents. In addition, subject references to positive connections with their past experiences were recorded as positive thoughts. Neutral thoughts were simply restatements of the ad contents. Negative thoughts were the opposite of positive thoughts. The total number of thoughts was obtained by summing the number of positive, neutral, and negative thoughts per ad. Order of mention of the ads by each subject was also recorded. The analysis of the ads by the two judges was generally in agreement (87%). A third person was utilized in settling disputes, with the majority opinion winning. RESULTS The percentage of subjects mentioning a particular brand being advertised was highest for the Bahamas (91%) and Bermuda ads (91%) in the first low noise treatment followed by Florida (88%) and Quebec (88%) in the second low noise treatment as shown in Table 1. In the high noise treatment only four ads TABLE 1 PERCENT AD MENTION IN LOW VERSUS HIGH NOISE CONDITIONS Advertisement First Low Noise Condition Bahamas Bermuda Colorado Change as a Percentage of Possible Change Low Noise High Noise Change 91 91 74 80 76 -11= 12 16 40 -34^ 46 36 -25"^ -33*^ 41 -38^ -22*' 51 38 -24^ 45 27 - 9« 12 Both Conditions Blue Stratos (1) Maxell (2) (1) (2) 61 69 74 58 36 48 Second Low Noise Condition Florida 88 48 Quebec Palm Springs 88 73 64 64 not significant V < .05 "p < .01 All tests were for significance of difference between two proportions. were mentioned by over 50% of the subjects: the Bahamas (80%), Bermuda (76%), and Quebec and Palm Springs (both 64%). Mentions for the BVD ad and the Camel ad, the two ads found only in the high noise treatment, were 20% for the former and 44% for the latter. The Maxell ad had greater mention (74%) among the ads in the first low noise condition than from those in the second low noise condition (58%). A decline in ad mention between the low and high noise conditions occurred for all ads. The greatest drops in ad mentions between the low noise and high noise conditions were for the Florida (40%), Colorado (34%), Maxell (30% on average) and Blue Stratos ads (29% on average). Looking at the decline in ad mentions as a percentage of possible change between the low and high noise conditions the Bahamas (12%), Palm Springs (12%), and Bermuda (10%) ads fared best. The mean numbers of positive, negative, neutral, and total thoughts verbalized by the subjects in each treatment for each ad were calculated. Table 2 contains the mean number of positive, negative, neutral, and total thoughts generated per ad in the high noise condition. The mean number of negative thoughts generated per ad varied significantly across ads at alpha = .005. The BVD undergarment ad elicited the greatest number of negative thoughts (X~= -68), followed by Camel cigarettes and Quebec (x"= -32 for both). The Florida, Palm Springs, and Bahamas ads received the fewest negative references. The means for positive, neutral, and total thoughts generated were not significantly different across ads. In the first low noise condition the means for the number of negative thoughts per advertisement were significantly different at an alpha of .10. In this treatment the Blue Stratos cologne ad generated the lEirgest number of negative thoughts and the Bahamas TABLE 2 HIGH NOISE CONDITION: NUMBER OF THOUGHTS PER ADVERTISEMENT Negative S.D.

A comparison of the mean number of neutxal thoughts generated per ad in the second low noise condition was significant at an alpha of .05. The means of total thoughts generated per ad in the same treatment were significantly different at alpha = .10. The Blue Stratos ad elicited the greatest number of both neutral and total thoughts, while the Palm Springs ad elicited the least number of neutral and total thoughts. All other differences among means were not significant because of the low value of the means and the h^h standard deviation associated with the means. Order of mention of the ads in each of the respective treatments was recorded. The Fisher and Yates transformation (1) was used to normalize the distribution of ranked data. For example, in the low noise conditions, the rank orderings of 1, 2, 3, 4, and 5 were recorded as 1.16, .50, 0, —.50, and —1.16 respectively. Low transformations were ass^ned randomly to ads not mentioned by each subject. The average number of ads mentioned {out of 5) by subjects in the first and second low noise treatments was 3.9 and 2.8 respectively. In the high noise condition an average of 5.1 ads was mentioned per subject. Table 3 contains the means and test for equality of means for the second low noise treatment. The Florida ad had the h^hest normalized mean (.53) followed by Quebec with a mean of .16. The ad mentioned last most often was Blue Stratos (—.40).

Some answers to this question can be learned by studying the verbal comments to ads mentioned frequently versus infrequently. Exhibits 2, 3, and 4 contain sample verbalizations for the three winning ads in terms of order of mention in the high noise condition. The Bahamas cognitive episodes, as represented in Exhibit 2, were brief. In spite of this, subjects recalled having viewed the ad, and tended to mention it first when recounting the ads they had seen. Reflections on the Bermuda ad (Exhibit 3) indicate EXHIBIT 2 EXHIBIT 3 BAHAMAS: HIGH NOISE CONDITIONSUBJECT COGNITIVE EPISODES BERMUDA: HIGH NOISE CONDITION SUBJECT COGNITIVE EPISODES Subject A Subject A There was a lot of advertisements about vacation spots like Bennuda. The one on Bahamas was all right. It had two girts enjoying the Bahamas, saying how great it was. It had pictures of tbem sailboating, and houses and blue skies and green grass. There was one Tor Bahamas. It had a couple laying on a beach and it said in the Bahamas you could be in a secluded place or you could be in I guess a busy shopping night life type place. But I think the best thing about it was they had in fine print at the bottom, was that there's a toll free number you could call if you had it you wanted more information about going to the Bahamas or what's there. Subject B The one on Bermuda kind of caught my eye. For Baham.., maybe this was Bermuda it was telling about how you know all there was to do in Bermuda. And it told about two girls. It's got these two great looking girls and it says this is what they had to say about their trip to Bermuda. And its them telling about you know the great time they had. And it shows them out in sailboats and all this kind o[stuff. Subject B Tbe one about tbe Bahamas looked interesting. Subject C that there was some confusion between the Bahamas and Bermuda ads. Even so, the content of the Bermuda ad was recounted in greater detail than that of the Bahamas ad. The general message of the Palm Springs ad (Exhibit 4) was remembered, but the emphasis in the verbalizations was on the cold north. Both subjects mentioned that there was just an inset picture of a Palm Springs scene. Perhaps this is why the Palm Springs ad did not fare as well as the Bahamas and Bermuda ads. Exhibit 5 contains the reflections of two subjects on the Blue Stratos ad. One subject experienced difficulty recalling the brand name, and the other went so far as to say that he probably wouldn't buy it because of the name. The first subject explicitly expressed disbelief with the "implied" claims of the ad and neither subject wanted to be associated with the image portrayed by a user of Blue Stratos cologne. This ad had low recall and was mentioned toward the end of the subject's verbalization because the brand name was hard to pronounce and was relatively unknown. Exhibit 6 contains sample verbalizations for the BVD ad. The cognitions indicate that subject responses toward the ad varied greatly. The short statements and rambling thoughts in the first episode suggest delayed thought processing and possibly an uneasiness with the ad. The person seemed taken aback that the ad was for undergarments. The second subject succinctly described the ad (without explicitly stating that the man was in underwear), named the sponsor, and expressed disgust with it. The low number of mentions and low priority given in order of mention for this ad was most likely intentional. It is probably a result of the unusual nature of the ad content There was one I think for Bermuda, and what it consisted of was three or four photographs of a couple, or you know just a few people playing tennis or laying on the beach or sometbing like that. Then it bas little quotes about it. It really. It wasn't an appealing ad. I really kind of think it was. . .It said something. . .One of the ladies.. .One thing I remember about it was one of the ladies said that she liked the idea of Bennuda shorts but then in the graphics then the picture showed the lady in Bermuda shorts I don't see how she.. . EXHIBIT 4 PALM SPRINGS: HIGH NOISE CONDITIONSUBJECT COGNITIVE EPISODES Subject A There was one on, I saw one that was on Palm Springs, California. It was an ad that basically was a contrast ad. It showed, you know, your typical northern city you know, it was raining and wet and cold and then its got a picture in the inset of Palm Springs, California, and it's you know the sort of thing like, come in out of the cold to California, this kind of thing. I think they could bave done a better job on that. I tend to favor southern California myself. It's one of my favorite spots and 1 think they could have done a better advertisement on that, is my feelings towards that ad. Subject B The ad on Palm Springs. It was good in that U depicted a city scene like New York, or what not, and you have a small inset picture in tbere of a couple swimming in a pool and the caption is something to the effect, 1 can't remember it, sometbing to the effect of being out of the cold. 10 (which may have made some individuals uncomfortable), and the fact that the subjects were required to relate the ad contents to individuals they were not acquainted with. EXHIBIT 6 BVD: HIGH NOISE CONDITION-SUBJECT COGNITIVE EPISODES Subject A Another one that I thought was kind of cute was about EXHIBIT 5 BVD men's underwear. But the one about the man's underwear: it said America's man is going to color. And so its got this guy standing there. He's got on blue tight underwear and a t-shirt, and he's standing there shaving, and youil probahly like that. Get her to show you that one. And, I don't know, it kind of struck me kind of funny, because I don't know if people are into underwear that much or not. But I mean, 1 know that I meant wouldn't look through a magazine trying to.. .1 thought that was kind of neat. It did kind of catch my eye. At first 1 didn't know, you know I didn't know it was talking about men's underwear. But you know. . .1 mean it just.. .It showed a guy standing there in his underwear, and he's shaving with a straight razor, and I thou^t it was going to say something else about an aftershave or something. Then it goes to tell how men are favoring colored underwear and going for that psychodelic look I guess. It was pretty neat. BLUE STRATOS: HIGH NOISE CONDITIONSUBJECT COGNITIVE EPISODES Subject A And another one was getting away like getting away from vacation was about a man's cologne and aftershave. I guess it's just coming out. I've never heard of it before but it's Status or Stratos or something like that and you know it telh about how it's brisk and free and all this kind of stuff and you're just going good, you know, how could a cologne make you feel like that. Well you know, you dash a little bit of this on and you know take off flying or something like that. Also it shows a guy in a hang glider you know going around and it describes it perfect. Subject B Subject B Another ad in there was one for a cologne for men. It was called Blue Stratos. The background picture was a man in a hang glider. I don*t think I'd ever use it, probably because of the name Blue Stratos. it's just not a name I think I'd pick up. Oh, there was one stupid ad that had a picture of a man for BVD underwear, undergarments and t-shirts and underwear, and it had a picture of a guy. It was sort of a macho-type thing — a sort of a country westem-type bathroom and a fellow shaving in his BVD's you know and he was wearing a cowboy hat. And I thought that was particularly stupid looking. . . CONCLUSIONS AND IMPLICATIONS Thought verbalizations are substantially less likely to include mentions of specific brand names in noise situations where consumers are exposed to many versus a few ads, i.e., high versus low noise conditions. The decline in brand name mentions is greater for some ads versus others in high versus low noise conditions. For example, the decrease in mentioning Palm Springs was nine percent versus 40 percent for Florida in high versus low noise conditions. Two implications can be drawn by these conclusions. First, exclusive or restrictive ad placements should be sought by advertisers: clutter should be avoided. Second, multiple ads for a given brand should be tested in high versus low noise conditions. Some ads placed in competition with others may be able to produce high brand mentions in both high and low noise conditions while others do not. First brand mention in unaided recall tests (top-ofthe-mind-awareness) has been found to be related positively to proportion of purchases for the brand (7). Thought processing research in low and high noise conditions enables the use of first brand mention as a surrogate for the potential sales impact of an ad. Does the ad for a given brand gain prime processing space in the consumer's mind? The results shown in Table 4 imply that the Bahamas and Bermuda ads may work particularly well in influencing sales by affecting awareness. Positive and Negative Thoughts Different ads produce widely differing numbers of positive and negative thoughts (see Table 2). Some ads are substantially more likely to produce negative versus positive thoughts and the reverse is likely to hold. Thus, ad testing to leam consumer thoughts before media placement should be considered by advertisers. Actual consumer thought responses may differ widely from the responses desired by advertisers. Thought processing pretests of ads before their media placement may reduce the possibility of negative thoughts being associated with the advertised brand and help the advertiser in selecting ads likely to produce positive thoughts.
