Employees' Perceptions of the Distributive Justice of Pay Raise Decisions: A Policy Capturing Approach

An examination was made of the factors that contribute to employee perceptions of the distributive justice of compensation outcomes and how employees differ in their perceptions. A sample of 414 employees of a large public university was used to assess what distributive rules are associated with employees' perceptions of the fairness of pay raise decisions. The results found that employees evaluated the fairness of pay raise decisions differently. A cluster analysis identified three groups of employees who differed in their perceptions, and one-way analysis of variance highlighted a number of demographic and attitudinal factors by which these groups were distinguished.     

Policy Capturing with Ridge Regression

A policy capturing method combining human judgment with ridge regression is offered which results in superior judgment policy models. The new method (termed smart ridge regression) was tested against four others in seven judgment policy capturing applications. Performance criteria were two cross-validation indices: cross-validated multiple correlation and mean squared error of prediction of new judgments. Smart ridge regression was found to outperform ordinary least squares regression and conventional ridge regression, as well as subjective weighting and equal weighting of cues.     

Using Invariance to Examine Cheating in Unproctored Ability Tests

Despite their widespread use in personnel selection, there is concern that cheating could undermine the validity of unproctored Internet‐based tests. This study examined the presence of cheating in a speeded ability test used for personnel selection. The same test was administered to applicants in either proctored or unproctored conditions. Item response theory differential functioning analyses were used to evaluate the equivalence of the psychometric properties of test items across proctored and unproctored conditions. A few items displayed different psychometric properties, and the nature of these differences was not uniform. Theta scores were not reflective of widespread cheating among unproctored examinees. Thus, results were not consistent with what would be expected if cheating on unproctored tests was pervasive.     

Using Reinforcement Learning to Examine Dynamic Attention Allocation During Reading

A fundamental question in reading research concerns whether attention is allocated strictly serially, supporting lexical processing of one word at a time, or in parallel, supporting concurrent lexical processing of two or more words (Reichle, Liversedge, Pollatsek, & Rayner, 2009). The origins of this debate are reviewed. We then report three simulations to address this question using artificial reading agents (Liu & Reichle, 2010; Reichle & Laurent, 2006) that learn to dynamically allocate attention to 1–4 words to “read” as efficiently as possible. These simulation results indicate that the agents strongly preferred serial word processing, although they occasionally attended to more than one word concurrently. The reason for this preference is discussed, along with implications for the debate about how humans allocate attention during reading.     

Policy Capturing: Discharge From the Israeli Army Due to Mental Difficulties

This study investigates decisions made by mental health officers in the Israeli army to recommend discharge from compulsory duty due to mental difficul- ties. It examines information cues available to the clinician that are predictive of that recommendation. The study is based on a content analysis of files on 154 soldiers who had been treated in one mental health clinic of the Israel Defense Forces. We found many cues that can predict recommended discharge. Mong with problems that became apparent during military service, significant items also related to problems prior to enlistment (e.g., in elementary and high school, social relations, mental health difficulties, and criminal activity). The overall R2 was above 73% in a stepwise hierarchical regression that entered variables in a chronological order. The findings and their implications are discussed in light of existing research.     

Judgments About Sexism: A Policy Capturing Approach

Different definitions of sexism have been usedby different experimenters and little attention has beengiven to the possibility that participants' definitionsof sexism might vary across individuals and across situations, just as the definitions ofinvestigators vary. Judgments about sexism areinextricably based on individual perceptions, values,and beliefs. It would seem reasonable, therefore toexamine individual conceptions of what constitutessexism. A total of 95 primarily middle-class Caucasianparticipants (68 females, 27 males) participated inthree studies investigating what information people use in deciding whether or not a male actor issexist. Six specific categories of information (or cues)were examined: (1) comments (or lack thereof) by theactor on a female target's physical appearance, (2) unwanted or inappropriate physical contact(or lack thereof), (3) assumptions (or lack thereof)about the target's work, personality, etc., based on hergender, (4) the target being interrupted (or not) by the actor, (5) an apparent powerdifferential (or lack thereof) between the actor and thetarget, and (6) assumptions by the actor aboutappropriate gender role behaviors. A policy capturingmethodology was employed in which three different sets ofscenarios, each describing a number of interactions(called profiles) between a target and an actor, werepresented to male and female participants who rated the degree of sexism exhibited by the actor ineach scenario. Policy capturing represents anideographic approach to research in which the primaryfocus is on establishing statistical parameter estimates that describe each individual's behavior in avariety of environmental situations. Only when that isaccomplished does the researcher examine the possiblenomothetic aggregations across participants. Thus many fewer participants are required than intraditional nomothetic approaches. Each profile set useda different subset of the cues which contained eithersubtle (Study 1), overt (Study 2), or very overt (Study 3)levels of the cues. Multipleregression analysis revealed that when relatively overtacts of sexism were described, most participants hadreliable policies; that is, their judgments werepredictable from the cues. However, when relatively subtleacts of sexism were described, most participants did nothave reliable policies; that is, their judgments werenot very predictable from the cues. There were large individual differences in howparticipants weighted the importance of various cues,especially with subtle cue levels, and in participants'mean sexism ratings.     

The Psychology of Restaurant Tipping1

Since its origins in 18th-century English pubs, tipping has become a custom involving numerous professions and billions of dollars. Knowledge of the psychological factors underlying tipping would benefit service workers, service managers, and customers alike. Two studies were conducted to provide such knowledge about restaurant tipping. The percent tipped in these studies was related to group size, the customer's gender, the method of payment (cash or credit), and in some cases, the size of the bill. Tipping was not related to service quality, waitperson's efforts, waitperson's gender, restaurant's atmosphere, or restaurant's food.     

Using the Analytic Hierarchy Process to Analyze Multiattribute Decisions

Since its introduction a decade ago, the Analytic Hierarchy Process (AHP) has been used by decision makers in many contexts. The vast majority of these applications has involved allocating resources or making choices from among alternatives. This article discusses how AHP may be used in a different manner: to assist researchers in the analysis of decisions. AHP is briefly compared with other decision-analysis techniques, such as multiattribute utility measurement, conjoint measurement, and general linear models (regression and analysis of variance). Some of the possible insights into decision processes that can be obtained using AHP are illustrated with data gathered from practicing auditors of financial statements.     

Using an Individual Differences Approach to Examine Two Distinct Types of Suggestibility Effects

Two studies were conducted to examine relations between suggestibility effects studied in two commonly used research paradigms and a group of individual difference factors that have been theoretically linked to eyewitness suggestibility. In Study 1, we examined relations between the immediate acceptance of misinformation as measured by errors on misleading questions and individual differences in conformity, agreeableness, imagery ability, and memory. As predicted, the immediate acceptance of misinformation was associated with conformity but was not related to imagery ability. In Study 2, we examined relations between delayed retrieval errors produced during a classic misinformation paradigm and the same set of individual difference factors. Consistent with our predictions, delayed misinformation retrieval errors were related to imagery ability but were not related to conformity or agreeableness. Taken together, this predicted pattern of results across the two studies provides some preliminary evidence for an emerging distinction between these two types of suggestibility effects. Underlying theoretical, methodological, and practical issues related to the assessment of suggestibility effects are discussed. Copyright © 2012 John Wiley & Sons, Ltd.     

The Influence of Perceived Deservingness on Policy Decisions Regarding Aid to the Poor

In the current climate of welfare reform, it is important to understand how perceptions of the poor affect policy decisions. This paper examines how people distinguish between the undeserving poor and the deserving poor, and how this differentiation affects policy decisions. Survey respondents rated each policy in a set of hypothetical policies on a liberal-conservative continuum. Analyses were then conducted to explore differences in the respondents' likelihood of recommending the most liberal and the most conservative of these policies. Study 1 demonstrated that liberal policies were more likely to be recommended and conservative policies were less likely to be recommended when the target group was perceived to be deserving rather than undeserving. Study 2 replicated this effect of perceived deservingness and demonstrated an effect of attribution of responsibility. That is, liberal policies were more likely to be recommended and conservative policies were less likely to be recommended when the responsibility for the target's poverty was attributed to society rather than to the individual.     

Effect of Server Posture on Restaurant Tipping1

The effect of server posture (standing vs. squatting) on the size of tip left by restaurant customers was examined in two naturalistic experiments. In these studies, squatting down next to the tables increased servers’ tips from those tables. Both the practical implications of this effect and its similarity to other nonverbal effects on tipping are discussed.     

Sweetening the Till: The Use of Candy to Increase Restaurant Tipping1

A common practice among servers in restaurants is to give their dining parties an unexpected gift in the form of candy when delivering the check. Two experiments were conducted to evaluate the impact of this gesture on the tip percentages received by servers. Experiment 1 found that customers who received a small piece of chocolate along with the check tipped more than did customers who received no candy. Experiment 2 found that tips varied with the amount of the candy given to the customers as well as with the manner in which it was offered. It is argued that reciprocity is a stronger explanation for these findings than either impression management or the good mood effect.     

Effect of Server Introduction on Restaurant Tipping1

The effect of a server introducing herself by name on restaurant tipping was investigated. Forty-two, 2-person dining parties were randomly assigned to either a name or a no name introduction condition. The use of a buffet brunch reduced contact between server and diners and held bill size constant. Results indicated that having the server introduce herself by name resulted in a significantly higher tipping rate (23.4%) than when the server did not introduce herself by name (15.0%), p < .001. Tipping rate also was affected by method of payment, with diners who charged the meal having a higher rate (22.6%) than those paying cash (15.9%), p < .001. The findings suggest the importance of initial server-diner interactions. Possible alternative explanations and suggestions for future research are provided.     

Extending the Knapsack: Using the White Privilege Analysis to Examine Conferred Advantage and Disadvantage

This article describes a self-awareness activity that utilizes a directed reading on privilege and a small-group discussion format to examine unearned disadvantage and unearned advantage in one’s life. This exercise can help clinicians to better understand systemic and individual sources of power and privilege in society. Beginning with my previous work on white privilege, students can extend this analysis to other domains of privilege, including, for example, gender, class, sexuality, age, nationality, and physical ability, to name a few. The primary goals of this reflective exercise are to help clinicians understand how clients’ lives are influenced by societal disadvantages and advantages, to encourage a new understanding of oneself, and to increase empathy towards clients.     

The Effect of Patriotic Messages on Restaurant Tipping1

This study compared the effectiveness of 2 types of patriotic messages with a warmth/ ingratiation message and a control condition on restaurant tipping. Two female food servers waited on 100 parties eating dinner. When diners were finished with their meals, servers left them 1 of 4 messages on their checks: “Have a Nice Day,”“God Bless America,”“United We Stand,” or no message. Results indicated that parties who received the “United We Stand” message left significantly higher tips than did those receiving no message or the “Have a Nice Day” message. No other significant differences were found. These results and their implications are discussed.     

The Social Norm of Tipping: A Review1

Tipping in U.S. restaurants alone amounts to $27 billion annually. Tipping is also common in other occupations and countries, making tipping a significant economic activity. The literature on tipping is spread over various disciplines: mainly psychology, economics, hospitality, and tourism. This survey article integrates the research conducted on tipping to allow an overview of the literature. In addition to summarizing and synthesizing the research on tipping, the article includes original ideas and suggests topics for future research.
