Fast similarities: efficiency advantages of similarity-focused comparisons

People constantly have to make efficient use of their limited cognitive resources. Recently, T. Mussweiler and K. Epstude (2009) demonstrated that comparative thinking simplifies information processing and increases the efficiency of judgment. However, there are different types of comparative thinking. While comparing 2 entities, people may focus on either similarities or dissimilarities between target and standard. The authors propose that these 2 comparative thinking styles differ in their efficiency. Specifically, the authors hypothesize that comparisons with a focus on similarities lead to more focused information processing and faster judgments than comparisons with a dissimilarity focus. In line with these hypotheses, the authors demonstrate that participants are indeed faster at judging the similarity of 2 stimuli (Study 1) and that they search for less target information in a comparative judgment task (Study 2) if they focus on similarities rather than dissimilarities. Focusing on similarities thus appears to be the more efficient comparative thinking style.     

Two sides of the same coin? On the history and phenomenology of chronic fatigue and burnout

Background: Burnout and chronic fatigue syndrome (CFS) are two fatigue syndromes which have developed largely independently from each other, yet whose similarities in symptoms can be a source of confusion. We aim to explore the phenomenology of burnout and CFS in a historical context as this may provide some insight into the links and relationship between these conditions. Method: A narrative review based on literature in the fields of history, social science and medicine. Results: The origins of CFS lie within medicine, whereas burnout developed in a psychological setting. As well as symptoms, burnout and CFS also share similar themes such as an overload process triggering illness onset, the need for restoration of depleted energy, external causal attributions and the characteristics of people suffering from these illnesses. However, these themes are expressed in either psychological or medical terms according to the historical background. Conclusion: Despite their similarities, there have been few direct comparisons of the two concepts. Culture, illness perceptions and accountability are important issues in both conditions and could contribute to their differences. Comparing burnout and CFS within one sample frame, thus looking beyond the psychology/medicine divide, could be a useful first step towards understanding their relationship.     

Political deviance and the assumption of responsibility

Political deviance is a broad concept, less frequently invoked than the concept of political crime. It can be perpetrated by those in power, in the name of the state or individually, or by those struggling to effect social change. The focus on the latter brings to the fore two types of movements, terrorism and civil disobedience, with their partial similarities in goals and their apparent dissimilarities in the means employed to achieve these goals. Both groups tend to assume responsibility for their acts, although for different reasons. The assumption of responsibility itself is a clouded and sometimes ambiguous notion, both linguistically and in its ramifications in the political arena.     

When I and me are different: assimilation and contrast in temporal self‐comparisons

In two studies, we show that comparisons with past or possible future selves shape current self‐evaluation and that the direction of this influence is determined by one's current comparison focus. In Study 1, participants primed to focus on similarities versus dissimilarities were asked to remember an introverted or extraverted past self and then to evaluate their current level of extraversion. Participants who focused on similarities assimilated current self‐evaluations to the past self, whereas those who focused on dissimilarities contrasted current self‐evaluations away from the past self. In Study 2, participants imagined a possible future self that differed from their current self in terms of body weight. Participants who imagined a moderate weight change exhibited assimilation to the possible self, whereas those who imagined an extreme weight change exhibited contrast. These studies highlight the important role cognitive factors such as comparison focus play in shaping the consequences of temporal self‐comparisons. Copyright © 2009 John Wiley & Sons, Ltd.     

Going Tandem

SUMMARY

This article takes a humorous, anecdotal look at relationships through the extensive use of metaphor. The author compares relationships to tandem bicycle riding. He offers comparisons and similarities from his relationship experiences both on and off the bike. The article offers opportunities for the reader to interact and respond from their relationship experiences.     

The malleable influence of social consensus on attitude certainty

People often reflect on the opinions of others and express greater attitude certainty when they perceive their attitudes to be shared by others (high attitude consensus). The present research tests the possibility that either high or low attitude consensus can increase attitude certainty depending on people's salient social identification needs. In particular, high attitude consensus with a target group is found to be more validating when people seek to belong to the group, as this identification motive promotes a search for similarities between themselves and the group. In contrast, low attitude consensus with a target group is found to be more validating when people seek to be unique from a group, as this identification motive promotes a search for dissimilarities between themselves and the group. Two experiments support these hypotheses, offering insight into the intra-personal motives that alter the diagnostic value of social consensus information.     

Stuttering attitudes among Turkish family generations and neighbors from representative samples

PurposeAttitudes toward stuttering, measured by the Public Opinion Survey of Human Attributes-Stuttering (POSHA-S), are compared among (a) two different representative samples; (b) family generations (children, parents, and either grandparents or uncles and aunts) and neighbors; (c) children, parents, grandparents/adult relatives, and neighbors of the same family/neighbor units vs. individuals from different family/neighbor units; and (d) attitudes from one Turkish city with an international database archive.MethodsFollowing a school-based, three-stage, cluster probability sampling scheme, two sets of children, parents, grandparents/adult relatives, and neighbors (50 each) in Eski?ehir, Turkey (PROB1 and PROB2) completed Turkish translations of the POSHA-S. The POSHA-S measures attitudes toward stuttering within the context of other attributes, such as obesity and mental illness.ResultsBoth replicates of the sampling procedure yielded strikingly similar attitudes for stuttering between children, parents, grandparents/adult relatives, and neighbors in PROB1 vs. PROB2, and between all pair-wise comparisons within PROB1 and PROB2. By contrast, attitudes toward obesity and mental illness were dissimilar. Correlations were small to moderate among attitudes of the same family/neighbor units but were essentially nonexistent between different family/neighbor units. Attitudes toward stuttering in Eski?ehir were estimated to be less positive than attitudes from a wide range of samples around the world, although exceptions occurred.ConclusionsA school-based probability sampling procedure yielded consistent findings that are likely different from results from convenience samples. Families appear to be an important influence in determining public attitudes toward stuttering and other human attributes.Educational objectives: The reader will be able to: (i) identify similarities and differences among attitudes toward stuttering across generations; (ii) identify similarities and differences among attitudes toward stuttering in Turkey vs. other places in the world; (iii) describe a school-based probability sampling scheme; (iv) describe advantages of using a standard instrument to measure public attitudes toward stuttering.     

Belief versus acceptance

Abstract

In this paper the problem of the relation between belief and acceptance is discussed in view of recent literature on the topic. Belief and acceptance are characterized in terms of a number of properties, which show both the similarities and the dissimilarities between these notions. In particular it is claimed — contrary to some recently expressed views — that acceptance need not be intentional action and that the differences between belief and acceptance do not boil down to the simple view that acceptance, contrary to belief, is based on the agent's direct exercise of his will. Acceptance which is not based on intentional action is shown in the paper to be especially closely related to belief, especially to linguistic belief. Thus if a person is in a non‐intentional‐ly acquired and held state of acceptance that something p, he also believes that p. Another general difference is that acceptance is language‐dependent while there can be non‐linguistic belief. Collective beliefs and acceptances are also briefly discussed in the paper Among other things, it is noted that the notion of wide as contrasted with truth‐oriented, narrow acceptance is central in the collective case.     

Mencius,Hume, and the virtue of humanity: sources of benevolent moral development

ABSTRACT

In this paper, we elucidate the moral psychology and what we might call the moral sociology of Mencius and of Hume, and we argue for three claims. First, we demonstrate that there are strong similarities between Mencius and Hume concerning some of the principal psychological sources of the virtue of humanity. Second, we show that there are strong similarities between the two concerning some of the principal social sources of the virtue of humanity. Third, we argue that there are related, though weaker, similarities between Mencius and Hume concerning some of the principal cognitive sources of the virtue of humanity. We conclude by suggesting that the number and nature of these similarities demonstrate the need for future research on the conceptual connections between Confucian and Humean moral philosophy, especially on the psychological and social sources of benevolent moral development.     

Experiences of older adults interacting with a shared autonomous vehicle and recommendations for future implementation

IntroductionA recognised potential benefit of autonomous vehicles is increased mobility for older adults. However, this group is more apprehensive about adoption, which may hinder uptake. Shared autonomous vehicles (SAVs) represent a use case that may be especially relevant for older people due to emerging applications in retirement villages and similar precincts. However, little research has examined the SAV-related concerns of older adults and strategies to address them. This study used an exploratory approach involving SAV exposure to identify strategies that may increase older people’s receptiveness to SAVs.MethodOlder adults living in retirement villages (n = 63) were interviewed while interacting with an SAV to examine their needs, expectations, and concerns regarding SAVs. The interview data were coded and thematically analysed.ResultsParticipants recommended the following approaches to ensuring SAVs are useful and acceptable to older adults: providing physical accessibility for those with mobility impairments, comfortable and practical internal layouts, and operating SAVs on convenient routes at useful speeds. Strategies such as exposing older adults to SAVs in operation to encourage uptake and initially ensuring a human assistant is present were suggested methods of increasing receptivity.DiscussionThe findings suggest older passengers are likely to share many of the same reactions to SAVs as the broader population, but with a stronger focus on issues relating to accessibility and the physical layout of the vehicles. The solutions to these issues suggested by the study participants may be useful for those designing SAVs for use in older people’s settings and beyond.     

Differences In the Importance of Selling Techniques Between Consumer and Industrial Salespeople

Abstract

The techniques involved in the personal selling process have been well documented in numerous sources over the years, but little research-based guidance has been provided to aid professional salespeople in the implementation of such techniques. The purpose of this research study is to examine the importance of 84 selling techniques, and cite the similarities and differences between consumer and industrial salespeople. The results indicate that consumer salespeople tend to rely more on other people, community contact, and standardized sales presentations than do industrial salespeople, while the latter rely more on company-supplied resources and partially standardized presentation styles.     

Changing Polish university students’ attitudes toward cluttering

PurposeThis quasi-experimental design study in Poland explored the extent to which attitudes toward cluttering of university students could be changed or improved after a series of activities dedicated to attaining deeper recognition of problems associated with fluency disorders.MethodUniversity students were assigned to either an Experimental or a Control group, with 39 in each (total = 78). They all completed the Polish version of the Public Opinion Survey of Human Attributes–Cluttering (POSHA–Cl) on two occasions up to eight weeks apart.Participants in the Experimental group attended the following intervention activities: watching and discussing an educational video on cluttering, participating in a workshop on the nature of cluttering, and watching and discussing a documentary on the life experiences of people struggling with fluency disorders. The Experimental group also filled out an open-ended questionnaire at the end of the study.ResultsPre-intervention comparisons indicated that participants assigned to either of the Experimental or Control groups differed significantly on 2 of the 15 summary ratings (13 %) of their pre-POSHA–Cl attitudes toward cluttering. For the Experimental group, the intervention resulted in significant positive changes in cluttering attitudes on 8 of the 15 summary ratings (53 %). In contrast, pre- and post- POSHA–Cl scores for the Control group were essentially unchanged (0 of 15 ratings).ConclusionsThis quasi-experimental study demonstrated that it is possible to positively modify the cluttering attitudes of university students. This has implications for the length, content, and experiential components of interventions designed to improve public attitudes toward fluency disorders.     

Do Immigrants Have Different Procedural Justice Perceptions of Personnel Selection methods? The case of native Israelis and immigrants from the former Soviet Union

Most prior research on perceived procedural justice vis‐à‐vis human resource management selection procedures focuses on comparisons between nations and between types of employees. So far, findings indicate slight, if any, differences between nations. Predicated on a random sample of 950 respondents – native Israelis and Israelis from the former Soviet Union – we find significant differences between the two groups concerning five selection methods, which we ascribe to inherent cultural dissimilarities. We attribute these differences to Hofstede's uncertainty avoidance dimension. These results may elicit increased focus on inherent cultural differences among potential employees with the view of considering these differences in opting for selection methods in order to accommodate for existing cultural differences. This consideration appears particularly pertinent in culturally diverse workforces, given the increased proportion of immigrants.     

Mental health and quality of life in non-binary transgender adults: a case control study

Abstract

Background: The social challenges that non-binary people experience, due in part to social intolerance and the lack of validation of non-binary gender identities, may affect the mental health and quality of life of this population. However, studies that have distinguished between non-binary and binary transgender identities are lacking.

Aim: To compare the mental health and quality of life of a community sample of non-binary transgender adults with controls (binary transgender people and cisgender people) matched on sex assigned at birth.

Method: A total of 526 participants were included. Ninety-seven were classified as non-binary and were compared with two control groups: 91 people classified as binary and 338 cisgender people. Only transgender people not on gender affirming hormone treatment or who had not undergone gender affirming surgery were included. Participants were invited to complete an online survey that included mental health and quality of life measures.

Results: Non-binary people reported significantly better mental health than binary transgender people, but worse than cisgender people. Overall, there were no significant differences in quality of life between non-binary and binary transgender participants assigned male at birth and transgender females, but non-binary assigned males at birth had better scores on the psychological and social domains of quality of life than transgender males. Quality of life was better across all domains in cisgender people than transgender groups.

Conclusion: There is an inequality with regard to mental health and quality of life between non-binary (and binary) transgender people and the cisgender population that needs to be addressed. The better mental health scores in non-binary people may reflect lower levels of body dissatisfaction among the non-binary population. Mental health problems and poor quality of life are likely to have social causes and hence legislative measures and broader government-led inclusive directives should be put in place to recognize and to validate non-binary identifying people.     

Spatial and conjoint models based on pairwise comparisons of dissimilarities and combined effects: Complete and incomplete designs

In pairwise multidimensional scaling, a spatial representation for a set of objects is determined from comparisons of the dissimilarity of any two objects drawn from the set to the dissimilarity of other pairs of objects drawn from that set. In pairwise conjoint scaling, comparisons among the joint effects produced by pairs of objects, where the objects in a pair are drawn from separate sets, are used to determine numerical representations for the objects in each set. Monte Carlo simulations of both pairwise dissimilarities and pairwise conjoint effects show that Johnson's algorithm can provide good metric recovery in the presence of high levels of error even when only a small percentage of the complete set of pairwise comparisons are tested.     

Plurality and prevalence of sexual motivations in a sample of young francophone adults

IntroductionUnderstanding the motivations that lead to the adoption of sexual behaviors is of major interest to both the individual and public health.ObjectivesThis work (i) questions the reasons that lead students from two French universities to adopt sexual behaviors, (ii) examines the motivational similarities and differences between men and women, (iii) compare the results to data from north American subjects.MethodIn total, 657 subjects (526 women; 131 men, mean age: 22.6 years) were requested to take part in an online study investigating sexual behaviors. Reason for Having Sex Questionnaire (Meston & Buss, 2007), was used as a basis for the identification of sexual motivations.ResultOn average 53.05 different motivations led to the adoption of sexual behaviors. Significant differences of men/women were found between men and women (72% significant differences in p < 0.05) but mainly of small amplitude (d < 0.33: 58.33%). Men and women also differ in the structure of interrelations between motivations and by the role played by the different motivations. Overall, female motivational system is more sectorized and more organized than the male system, which seems more resilient (density of interrelations Men: 46.3%; women: 34.2%; distance between motivations: 5.44 vs. 3.86, p < 0.001, d = 2.07). Cultural comparisons showed significant differences of low to moderate amplitude between young adult students in France and those who come from North American universities. Gender differences in sexual motivations for sex were more marked in France than in the US.ConclusionOur results argue for a bio-psychosocial and systemic approach of sexual motivations. Theoretical, methodological and practical perspectives are envisaged.     

Two boys—one event

The background of this paper is an investigation of child survivors from the Holocaust; in a study of interviews of these survivors, it could be concluded that past traumatic experiences are recovered not as memories (in the usual sense of the word), but as affects invading the present. Accordingly, affects seem to tell the story of the past traumatic experiences. In this paper, the author investigates two accounts (separately told by two survivors) of the same event in the Kielce ghetto. The two accounts present similarities, but also differences, and the author discusses these in relation to the concepts of historical and narrative truth, as well as in relation to construction and reconstruction, concluding that the interviews give a sketch of how the experiences have become idiosyncratically registered in the minds of the interviewees.     

Different and similar at the same time: when the activation of dissimilarity makes people look more similar

Whether two people are presented as similar or different may have a strong impact on the outcome of their comparison. In the present research, we examined the counterintuitive hypothesis that activating dissimilarity increases the perception of similarities between people, in other words increases perceived feature overlap, during the comparison process. We investigated this prediction by asking people to judge the perceived similarity between two faces with a suboptimally related or unrelated morph inserted in between (to influence joint categorization), and with similar or different facial expressions (to vary the salience of similar or different features). The results confirmed our expectations: In the similarity (joint categorization) condition, two faces that differed in expression were perceived as more dissimilar than faces with the same expression. More important for our prediction, in the dissimilarity condition two faces with different expressions were no longer perceived as more dissimilar than two faces with the same expression. We discuss implications of these findings for the mechanisms underlying comparisons between people. Copyright © 2007 John Wiley & Sons, Ltd.
