A rational origin obtained by the method of contingent paired comparisons

A new paired comparison method, based upon choices between lotteries, is developed for the measurement of utilities of objects with respect to the utility of receiving nothing, i.e., the status quo. The method is used to estimate the utilities of four birthday gifts. These objects had also been studied in an earlier experiment which used choices between single objects and pairs of objects to determine a rational origin. A comparison of the results of the two experiments indicates that both methods scale objects with respect to the same rational origin and unit of measurement.This research was supported under contract AF 49(638)-724 with the Air Force Office of Scientific Research and contract DA 19-129-QM-1045 with the Quartermaster Research and Engineering Command.     

The effects of social vigilantism and masculine honor beliefs on perceptions of confrontation during the COVID-19 pandemic

Varying opinions about the COVID-19 pandemic inspire different behaviors (e.g., mask-wearing), and confrontation may result between people with differing viewpoints. Individual differences associated with belief superiority (e.g., Social Vigilantism; SV) and/or pride (e.g., Masculine Honor Beliefs; MHB) likely related to third-person perceptions of pandemic confrontations. In this study (N = 237; US sample), we used vignettes in a 2 (Mask: Yes/No) ×  2(Confrontation Response: Vocal Defense/Walked Away) between-groups design to examine how SV and MHB predict perceptions of (1) responses to public confrontation about (not) wearing a mask and (2) the person being confronted. In general, mask-wearing and walking away from confrontation were perceived more positively. Higher SV was associated with more positive perceptions of seemingly morally-justified responses to confrontation (e.g., walking away when confronted for not wearing a mask, vocally defending oneself when confronted for wearing a mask). Contrarily, higher MHB were associated with more positive perceptions of non-mask-wearing. This research provides insight about how individual differences in SV and MHB relate to nuances in pandemic confrontations, and responses to confrontations, about (non)mask-wearing.     

Predicting Personality Stability Across the Life Span: The Role of Competence and Work and Family Commitments

Longitudinal studies suggest modest continuity in personality from adolescence to early adulthood and greater continuity over successive periods during the adult years. However, individual differences in personality stability do exist. We discuss potential sources of personality change, especially as they relate to development, role assumption and commitment, and loss of roles and commitments. Then, using data from the Intergenerational Studies, we employ measures of competence and of work and family commitments, assessed both in high school and adulthood, to predict personality stability from high school to early and late adulthood. Results indicate that personality stability can be successfully predicted with such measures. Greater personality stability is found for those determined to be more planfully competent, but additional family and work role variables also increase predictive power, in some instances. Using two alternate measures of competence—one from the California Q-sort and the other from the California Psychological Inventory—we replicated the finding that men with more disorderly careers show less personality stability, and that women who have experienced more divorces show less personality stability.     

A COMPARISON OF REINFORCER ASSESSMENT METHODS: THE UTILITY OF VERBAL AND PICTORIAL CHOICE PROCEDURES

We compared three methods of stimulus preference assessment for verbal children and specifically evaluated the utility of a verbal choice procedure for assessing relative reinforcer value. Using a token system, relative preference for five categories of reinforcers, representing 15 different stimuli, was assessed by three methods: a reinforcer survey, a verbal stimulus-choice questionnaire, and a pictorial stimulus-choice procedure. Results showed that the verbal and pictorial stimulus-choice assessments accurately identified high- and low-preference categories for 3 of 4 participants. Survey results alone often rated multiple categories as high preference, were less likely to identify low-preference categories, and were less likely to correspond with the results of a reinforcer assessment.     

The assessment of trust orientation

The development of the Trust Inventory, a 40-item measure of trust in generalized others (Generalized Trust) and romantic partners (Partner Trust) is described. A third conceptualization of trust in friends and family members (Network Trust) is also discussed College students (N = 1,229) participated in five stages of test construction and validation. Results indicated that the Trust Inventory scales are reliable, both internally and temporally, and that the Partner Trust and Generalized Trust Scales demonstrate both concurrent and construct validity. The resulting inventory is unique in its capacity to assess these types of trust simultaneously. Evidence supporting the discriminant validity of the Network Trust was mixed, whereas factor analytic treatments of Trust Inventory items supported the distinctiveness of Network Trust as compared to Partner and Generalized Trust, the Network Trust Scale correlated to roughly the same degree as the other two scales with several variables of differential theoretical relevance. Thus, little evidence supporting the incremental validity of Network Trust was observed Discussion focuses on the evidence suggesting the validity of interpretations of Generalized and Partner Trust and considers the issue of additional research regarding Network Trust.     

Effects of attentional set and rhythmic complexity on attending

In a target detection task involving sustained attentional monitoring, rhythmic properties of tone sequences were found to affect detection performance (area under receiver-operating characteristic curves) and reaction times. Alternating tone frequencies (high, low) formed three different recurrent rhythms (binary, trinary, mixed) which varied in complexity. Attentional set was also manipulated so that participants attended either to tones of both frequencies (divided) or to only the higher of the two tones (selective). The most interesting finding involved an interaction between attentional set and rhythm, indicating that selective attending is enhanced by the most complex (mixed) rhythm, whereas divided attending tends to be best with the simplest rhythm (binary). Results are discussed in terms of a theory of dynamic attending, in which it is assumed that listeners actively use attending oscillators to direct attending.     

The empirical investigation of factors affecting graphical visualization

An estimated 2.2 trillion graphs were published during 1994. These graphs used a multitude of different visual techniques in an effort to communicate information to a reader. Despite the many important applications for which graphs are used and the frequency of their use, little is known about what techniques make a graph most effective at communicating information to a reader. This paucity of knowledge stems largely from a dearth of empirical investigations pertaining to graphs. A major problem encountered by researchers who wish to undertake sound empirical research into the effectiveness of graphical presentations is the shortage of suitable tools. This article presents a computer software tool, Graphics Visualization, which offers the researcher an inexpensive yet accurate and reliable method of performing empirical research into factors that affect the accuracy and speed by which a reader can interpret data encoded within a graph.
