In spite of the over 50 years which have passed since the original experiments conducted by Stanley Milgram on obedience, these experiments are still considered a turning point in our thinking about the role of the situation in human behavior. While ethical considerations prevent a full replication of the experiments from being prepared, a certain picture of the level of obedience of participants can be drawn using the procedure proposed by Burger. In our experiment, we have expanded it by controlling for the sex of participants and of the learner. The results achieved show a level of participants’ obedience toward instructions similarly high to that of the original Milgram studies. Results regarding the influence of the sex of participants and of the “learner,” as well as of personality characteristics, do not allow us to unequivocally accept or reject the hypotheses offered.

One Serious Shock Versus Gradated Series of Shocks: Does “Multiple Feet-in-the-Door” Explain Obedience in Milgram Studies?

Dariusz Dolinski; Tomasz Grzyb

ABSTRACT From among the alternative interpretations of the astonishing servitude of study participants in Stanley Milgram experiments, a particularly suggestive one is Steven Gilbert’s. He asks the rhetorical question of whether one person would agree to administer a high-strength shock to another person under conditions where the demand to do so was advanced at the very beginning. This question has been the subject of two empirical studies. The results we have achieved do not, however, indicate that Gilbert’s conception is accurate in respect of situations created in experiments conducted consistently with the paradigm of studies by Milgram.

Perpetrator as a Potential Victim. Does Threatened Retaliation from the Victim Reduce Obedience towards Authority

Tomasz Grzyb; Dariusz Dolinski

In an experiment conducted within the Milgram paradigm, it was examined whether obedience towards an authority would be reduced in conditions in which the teacher had grounds to fear revenge from the learner. A comparison was made of the behaviour of participants in classic conditions and in conditions in which they were told that following the first part of the experiment, there would be an alteration of roles: the teacher would become the learner. It turned out that the level of compliance was the same in both groups. The dominant behaviour, regardless of whether the participant expects a change of roles or not, is total obedience.

Beliefs about Obedience Levels in Studies Conducted within the Milgram Paradigm: Better than Average Effect and Comparisons of Typical Behaviors by Residents of Various Nations

Tomasz Grzyb; Dariusz Dolinski

The article presents studies examining whether the better than average (BTA) effect appears in opinions regarding obedience of individuals participating in an experiment conducted in the Milgram paradigm. Participants are presented with a detailed description of the experiment, asked to declare at what moment an average participant would cease their participation in the study, and then asked to declare at what moment they themselves would quit the experiment. It turned out that the participants demonstrated a strong BTA effect. This effect also concerned those who had known the results of the Milgram experiment prior to the study. Interestingly, those individuals—in contrast to naive participants—judged that the average person would remain obedient for longer, but at the same time prior familiarity with the Milgram experiment did not impact convictions as to own obedience. By the same token, the BTA effect size was larger among those who had previously heard of the Milgram experiment than those who had not. Additionally, study participants were asked to estimate the behavior of the average resident of their country (Poland), as well as of average residents of several other European countries. It turned out that in participants’ judgment the average Pole would withdraw from the experiment quicker than the average Russian and average German, but later than average residents of France and England.

The (doubtful) role of financial reward in obedience to authority

Dariusz Dolinski; Tomasz Grzyb

ABSTRACT The Milgram experiments are among the most well-known and important in the history of psychology. Since first published, there have been countless discussions held on the subject of what factors induce people to exhibit extreme obedience towards authority. One such potential factor, not yet explored empirically, is the receipt in advance of financial gratification by a study participant. In our experiment we compare obedience among participants in classic Milgram paradigm conditions with obedience in a situation where the participant does not receive financial gratification in advance. The results did not show that obedience differed in the two comparable situations. In conditions where the participants were not given money up front, however, it was necessary to employ more verbal prompts in order to induce obedience.

Is Product Placement Really Worse Than Traditional Commercials? Cognitive Load and Recalling of Advertised Brands

Tomasz Grzyb; Dariusz Dolinski; Agnieszka Kozłowska

Considering the large number of adverts inundating the average consumer every day, the marketing industry is seeking methods to reach clients in a more subtle manner than traditional marketing messages. One such tool is product placement. The article addresses issues of effectiveness of product placement in comparison to a traditional commercial. The objective of the study was to check how participants would recall the content of persuasive messages in conditions of artificially inducted cognitive load (in conditions of traditional advertisement and product placement). Two studies were conducted – a pre-study intended to assess the usefulness of the selected stimuli, and the main experiment. The experiment devoted to this question was planned using an ANOVA scheme 2 (Type of advert: traditional vs. product placement) × 2 (neutral conditions vs. cognitive load). It turned out that the commercial was better retained in neutral conditions than in conditions of cognitive load. The traditional commercial was remembered better than product placement. From the perspective of the study’s ecological validity, of importance is also comparison of retention of brands viewed in a traditional commercial in conditions of cognitive load with retention of brands in conditions of product placement without load. These comparisons indicate the superiority of product placement – brands presented in this manner were more frequently recalled by viewers.

Temporal Aspects of the Chameleon Effect and Hospitality: The Link Between Mimicry, Its Impact, and Duration

Wojciech Kulesza; Dariusz Dolinski; Kinga Szczęsna; Mariola Kosim; Tomasz Grzyb

In an experiment conducted in natural settings (in a restaurant), we explore the uninvestigated link between mimicry, its impact on hospitality, and the time during which the mimicry takes place. Under particular experimental conditions, the waitress either did not verbally mimic the customer, mimicked the customer only at the initial stage of the interaction, only at the final stage of the interaction, or at both the initial and the final stage of the interaction. The tip left by the customer and its amount were the indicators of the hospitality experienced throughout the time spent in the restaurant. The outcome was that both indicators of noticeable hospitality were the highest where the verbal mimicry was applied twice.

The question-behaviour effect in intergroup attitudes research: When do attitudes towards a minority predict a relevant behaviour?: THE QUESTION-BEHAVIOR EFFECT

Katarzyna Byrka; Tomasz Grzyb; Dariusz Dolinski

We hypothesised that the question-behaviour effect, referred to as the influence of questioning about a given behaviour on its subsequent performance, is a relevant issue when exploring the external validity of intergroup attitudes. In a pair of studies, we have corroborated that merely expressing attitudes towards the Jewish minority affects peoples relevant behaviour towards this group. In an Internet study, participants who first completed verbal attitude measures were more likely to donate to a Jewish organisation compared to those who completed the measures after making the decision to donate. Moreover, responses to attitude measures of various types and donating to the Jewish organisation were correlated when attitudes had been expressed in the first step. When attitudes were measured after the decision to donate, only the responses to the traditional anti-Semitic scale were correlated with this behaviour. In the field study, in which the time interval between attitude and behaviour measures was introduced, no question-behaviour effect was observed. We explain the results with reference to cognitive dissonance and attitude accessibility mechanisms and discuss them in a broader context of attitude-behaviour research.
