The Effectiveness of Ethics Education: A Quasi-Experimental Field Study

Ethical conduct is the hallmark of excellence in engineering and scientific research, design, and practice. While undergraduate and graduate programs in these areas routinely emphasize ethical conduct, few receive formal ethics training as part of their curricula. The first purpose of this research study was to assess the relative effectiveness of ethics education in enhancing individuals’ general knowledge of the responsible conduct of research practices and their level of moral reasoning. Secondly, we examined the effects of ethics education on the positive psychological outcomes of perspective-taking, moral efficacy, moral courage, and moral meaningfulness. To examine our research hypotheses, we utilized a pretest–posttest quasi-experimental design consisting of three ethics education groups (control, embedded modules, and stand-alone courses). Findings revealed that both embedded and stand alone courses were effective in enhancing participants’ perspective-taking, moral efficacy, and moral courage. Moral meaningfulness was marginally enhanced for the embedded module condition. Moral judgment and knowledge of responsible conduct of research practices were not influenced by either ethics education condition. Contrary to expectations, stand alone courses were not superior to embedded modules in influencing the positive psychological outcomes investigated. Implications of these findings for future research and practice are discussed.     

Staring and Compliance: A Field Experiment on Hitchhiking

A field experiment was conducted in which a single male, a single female, or a male-female couple attempted to hitch rides at four different traffic locations, under conditions in which the hitchhikers either stared at or looked away from oncoming drivers. It was found that staring increased the probability of a driver stopping from .03 to .067 (z = 2.96, p = .003). The female was a more successful hitchhiker than either the male or the couple, (z = 2.215, p = .026; z = 1.861, p .063, respectively).     

The Influence of Identity Salience on Framing Effectiveness: An Experiment

Efforts to influence attitudes on highly polarizing issues, such as climate change, often fail because individuals interpret political messages through the lens of their partisan identities. However, shifting the identity lens through which an individual interprets a message may result in more effective political communication. Through a preregistered survey experiment (n = 978), this study tested how priming either a partisan or a nonpartisan (parental) identity influenced the effectiveness of a climate change frame on several attitudinal outcomes. Findings suggest that identity salience—specifically partisan identity salience—can influence the effectiveness of a frame. Among Republican parents, receiving a message about the impact of climate change on future generations increased climate change concern and intended proclimate political behaviors, but this framing effect disappeared when a partisan identity was first primed. Among Democrat parents, framing had no significant effect until a partisan identity was first primed. The findings offer important insight into the role that identity salience plays in framing effectiveness and suggest that political communication on polarized issues is likely to be more effective at building bipartisan agreement when nonpartisan identities are salient.     

Petitioner's Attire and Petition Signing by Peace Demonstrators: A Field Experiment1

Two female experimenters, one dressed as a “hippie” and the other wearing “straight” dress, solicited signatures for an anti-war petition at the April 1971 Washington peace demonstration. Although the petition was identical in both conditions, and a large degree of attitudinal homogeneity in the subject population could be assumed, the hippie condition produced more signatures, more subjects who signed without looking at the petition, and attracted a larger number of unsolicited signatures. These differences were attributed to the effect of implied attitude (reference group) similarity between experimenters and subjects in the hippie and dissimilarity in the straight condition; in-group members were more effective than out-group members, despite experimenter-subject similarity in explicit attitudes under both conditions.     

Telephone Interviewing: A Reappraisal and a Field Experiment

A review of 25 empirical evaluations of telephone interviewing indicated that the method compares favorably with face-to-face interviewing in terms of the range of subject matter that can be covered, length of interview, response rates, quality of data, and, most conspicuously, cost. In order to surmount some of the limitations of previous empirical comparisons of the two interviewing methods, a field experiment was conducted wherein 93 interviewers administered either face-to-face or telephone interviews to 470 similarly selected household respondents. Although the two methods did not differ significantly in terms of response rates, codeability of data, or reporting on sensitive issues, they did differ somewhat in interview length and the sex composition of the samples obtained.     

The Role of Nonperformance Factors on Job-Related Relocation Opportunities: A Field Study and Laboratory Experiment

Two studies examined the role of employee gender, marital type (single-earner, dual-earner), and parental status in understanding differential access to job opportunities requiring relocation, as well as possible perceptual processes underlying these effects. A large-scale field study (Study 1) found that married women and employees in dual-earner marriages were provided fewer relocation offers than married men and those in single-earner marriages. A laboratory experiment (Study 2) extended Study 1 by examining the perceptual process by which these nonperformance factors affected relocation opportunities. Again, married women and employees in dual-earner marriages received lower recommendation ratings for jobs requiring relocation compared to married men and single-earners, respectively. Further, decision-makers' perceptions of an applicant's willingness to relocate, family resistance to moving, and ease of adjustment to a geographic move partially mediated the relationship between these nonperformance factors and relocation opportunities. Implications for research and applied practice are discussed.     

Effects of Job Redesign: A Field Experiment1

A telephone company project to redesign the job of directory assistance operator was: studied in order to determine the effects on workers of “job enrichment” programs. The change increased the amount of variety and the decisionmaking autonomy in the operator's job. However, no change in work motivation, job involvement, or growth need satisfaction occurred as a result of the changes; instead, the changes had a significant negative impact on interpersonal relationships. After the changes, the older employees reported less satisfaction with the quality of their interpersonal relationships, and those supervisors whose jobs were affected by the changes reported less job security and reduced interpersonal satisfaction. Implications of these findings for the theory of job redesign proposed by Hackman and Lawler (1971) are discussed.     

Consumer Perception and Evaluation of Waiting Time: A Field Experiment

We varied telephone waiting times for a commercial service in 2 different experiments. In the 1st experiment, the telephone rate was either 0 or fixed at Dfl 1 (approximately $0.40) per minute. Consumer perceptions of waiting times could be described best by a psychophysical power function. Furthermore, wait evaluations were mainly influenced by the difference between the consumers’ acceptable and perceived waiting times. The negative effect of perceived waiting time on wait evaluations was increased by the monetary costs of waiting. In the 2nd experiment, the waiting times were filled in different ways: with music, queuing information, and information about expected waiting time. Information about the expected waiting time significantly reduced the overestimation of waiting time, although it increased the negative effect of perceived waiting time on wait evaluations.     

Impact of Internal Auditing on Branch Bank Performance: A Field Experiment

We conducted an experiment to assess the contribution of internal auditing to organizational effectiveness. We randomly assigned 224 bank branches to experimental conditions (audited or not audited) and monitored their performance for a year. Performance significantly improved during the half year following the audit in the experimental branches, in contrast to a decline in the control branches due to poor general business conditions. The contribution of auditing to performance is discussed in terms of learning, motivation, deterrence, and process improvement.

The Effects of Coachee Personality and Goal Orientation on Performance Improvement Following Coaching: A Controlled Field Experiment

This study presents a field experiment to test the question: What are the individual characteristics that influence whether coaching is beneficial for people’s performance? We focus our attention on the Big Five personality traits, core self-evaluations, and goal orientation. Using a control group for comparison, coaching was provided to a sample of working adults (N = 84) and both self-ratings and supervisor-ratings of performance (N = 74) were measured over three time points. Our analysis indicates that individuals high in Openness, who avoid goal orientation and are low in core self-evaluations benefit the most from coaching. We contribute to the literatures on coaching effectiveness and the wider learning and development literatures by providing an empirically robust examination of the interaction between individual differences and coaching and the subsequent impact on performance. Furthermore, our findings suggest that coaching may be an effective development technique for individuals who tend to perform less well in other forms of instructional learning due to their individual characteristics.     

Blowing the Whistle on Data Fudging: A Controlled Field Experiment1

This experiment examined determinants of “whistle blowing,” the disclosure of organizational wrongdoing. Previous research, limited largely to analyses of cross-sectional, self-reported data, has not established cause-effect relations, and dispositional variables generally have not been examined. In this study, 295 students witnessed apparent wrongdoing by a research assistant and were given an opportunity to report it to a university authority. Results indicated that men were more likely than women to report the wrongdoing. Whistle blowing also was a function of lower, rather than higher, levels of moral judgment development. More whistle blowing occurred when there were more, rather than fewer, observers of wrongdoing. Implications for research and practice are descried.     

Implementing Realistic Job Previews and Expectation-Lowering Procedures: A Field Experiment

A field experiment was conducted to assess the effects of preemployment interventions on newly hired telemarketers. The procedures used were a realistic job preview (RJP), an expectation-lowering procedure (ELP), a combination (RJP & ELP), and the control condition (minimal socialization). While we know these procedures enhance the integration of newcomers to an organization, we do not know the optimal combination of RJP and ELP in the employee socialization process. The three procedures yielded relatively lower expectations than did the control group. Participants in the experimental conditions (ELP, RJP, and ELP & RJP) reported significantly lower expectations than did the control group. The lowered expectations, however, did not result in higher retention rates in all of the conditions. The RJP & ELP combination resulted in the largest number of days worked, the major criterion of interest in this study. There was no significant difference in number of days worked between the control group and the RJP group. The current study indicates that a non-job-specific ELP in combination with an RJP may exceed the benefits of an RJP or an ELP used alone. Furthermore, organizational implications regarding the different procedures are discussed.     

Threat as a Motivator of Political Activism: A Field Experiment

The research reported here examined the effects of two potential motivators of political activism—policy change threat and policy change opportunity—in a field experiment. Different versions of a letter were sent by a political lobbying organization to potential contributors. One version highlighted threats of undesirable policy changes, another version highlighted opportunities for desirable policy changes, and the third version did neither. Policy change threat increased the number of financial contributions made to the interest group, but policy change opportunity did not. Policy change opportunity increased the number of signed postcards returned to be sent to President Clinton, but policy change threat did not. These findings highlight the impact of interest group recruitment strategies on citizen responsiveness and demonstrate the need to account for sources of motivation in order to more fully understand when, why, and how citizens choose to become politically active.     

Changing Peer Perceptions and Victimization through Classroom Arrangements: A Field Experiment

The purpose of this study was to determine the effect of an experimental manipulation of distance between classmates on peer affiliations and classroom climate. Participants were 651 10-to-12 year-old children (48% boys) from 27 Grade 5 and Grade 6 classrooms of 23 schools, who were assigned to an experimental or a control condition. Peer affiliations were assessed with peer nominations and likeability ratings before and after the manipulation of distance. In the experimental condition, children who did not like each other were placed closer together for several weeks in order to promote more positive peer relations. The decrease in distance lead to higher likeability ratings for children who were perceived most negatively at the beginning of the school year. In addition, a reduction in peer-reported victimization and social withdrawal nominations was found. The results suggest that the classroom seating arrangement can be used as a tool to improve liking among peers and reduce peer-reported problem behaviors in the classroom.     

The Influence of Videoconference Technology and Interview Structure on the Recruiting Function of the Employment Interview: A Field Experiment

This field experiment examined whether interview medium and interview structure affects the attractiveness of organizations, interviewer friendliness and performance. Attractiveness ratings of 25 organizations were provided by 92 real job applicants, assigned to either a face–to–face (FTF) or a videoconference (VC) interview. An interview medium X structure interaction showed FTF applicants were attracted most to organizations who conducted their interviews with less structure, while VC applicants were more attracted to organizations using structured interviews. Interview structure had no effect on applicants’ perception of the interviewer’s performance; however, interviewers’ performance was rated higher for FTF than VC interviews. Applicants were more satisfied with their FTF performance in less structured interviews and more satisfied with their VC performance in highly structured interviews.     

The Effect of Music on Atmosphere and Purchase Intentions in a Cafeteria1

This exploratory study investigates the effect of music on the perceived characteristics of a commercial listening environment and on customers' purchase intentions therein. Three musical styles and also no music were played in a student cafeteria over the course of 4 days. Subjects' responses to a questionnaire indicated that different musical styles had different effects on the perceived characteristics of the cafeteria, and that classical music was associated with subjects being prepared to pay the most for food items on sale therein. There was also some indication that classical and pop music might have increased actual sales in the cafeteria, as compared with easy listening and silence. These results are discussed in terms of their implications for both commercial practice and our theoretical understanding of music and consumer behavior.
