Ideological differences in attitude and belief similarity: distinguishing perception and reality

ABSTRACT

Attitude and belief similarity have long stood as topics of inquiry for social psychology. Recent research suggests that there might be meaningful differences across people in the extent to which they perceive and actually share others’ attitudes and beliefs. I outline research examining the relationship between political ideology and the perception and reality of attitude similarity. Specifically, I review research documenting that (a) conservatives perceive greater ingroup similarity than do liberals, (b) conservatives overestimate and liberals underestimate ingroup similarity, (c) liberals and conservatives both underestimate similarity to outgroup members, and (d) liberals possess more actual ingroup similarity than do conservatives on a national level. Collectively, this review contributes to understanding how political ideology relates to (perceived) attitude similarity.     

Similarity and Social Interaction: When Similarity Fosters Implicit Behavior Toward a Stranger

ABSTRACT

People interact more readily with someone whom they think they have something in common with. At a pedestrian crossing, confederates asked participants for the time and, in one condition, said she/he had the same watch as the participant. The amount of time that participants lingered near a confederate was used as the dependent variable. Participants in the similarity condition spent significantly more time near the confederate than when no similarity was manipulated. The results showed that similarity fosters implicit behavior, adding to the growing body of data on the positive effects of similarity and its role in social interaction.     

A PHYSIOGNOLINGUISTIC APPROACH TO READING ASSESSMENT: AN ALTERNATE FORM OF MISCUE ANALYSIS

This article is a good natured parody of an area of controversy, informal classroom reading assessment, which has been receiving a great deal of journal coverage in recent years. Any similarity between this article and actual research being conducted is completely gratuitous.     

Similarity to prototypical heavy drinkers and non-drinkers predicts AUDIT-C and risky drinking in young adults: prospective study

Objective: The aim of the present study was to explore whether constructs within the Prototype Willingness Model (PWM) predicted risky drinking as measured by AUDIT-C, drinking harms and unplanned drunkenness in a sample of UK young adults. Previous studies exploring the PWM often do not use validated measures of alcohol consumption, and the outcomes of risky drinking are underexplored. Design: An online prospective study design with 4 week follow-up was employed and 385 young adults completed the study (M age?=?21.76, SD?=?3.39, 69.6% female; 85.2% students). Main outcome measures: Intentions to get drunk, AUDIT-C, drinking harms experienced in the last 4 weeks, and unplanned drunkenness in the last 4 weeks. Results: Heavy and non-drinker prototype similarity predicted AUDIT-C, drinking harms and unplanned drunkenness when controlling for past behaviour and reasoned action pathway constructs. Intentions and willingness both mediated the relationship between prototype perceptions and AUDIT-C. Conclusion: This study supports the use of the PWM in the prediction of AUDIT-C, drinking harms and unplanned drinking in a UK sample. Prototype perceptions influenced behaviour via both reasoned and reactive cognitions. Targeting similarity to heavy and non-drinker prototypes should be the focus of future interventions in this population.     

Associations between abstainer,moderate and heavy drinker prototypes and drinking behaviour in young adults

Objective: Previous research has focused mostly on abstainer and/or general drinker prototypes. The present studies examined an abstainer, moderate drinker and heavy drinker prototype in relation to drinking behaviour.

Design: Two studies among young adults aged 18–25 (paper-and-pencil, cross-sectional, N?=?140; online, prospective, N?=?451) assessed prototype favourability and participants’ perceived similarity to the prototypes. Participants were also categorised into abstainers, moderate, and heavy drinkers.

Results: Similarity and favourability had similar sequences in both studies: the moderate drinker and abstainer prototypes were evaluated most favourable and felt similar to; the heavy drinker prototype was rated the least favourable and felt similar to. Importantly, heavy drinking participants felt most similar to the moderate drinker prototype and rated the heavy drinker least desirable. The results suggest a need for research to include other prototypes, such as the moderate drinker, besides the abstainer and heavy drinker.

Conclusion: The studies provide insights into the contribution of alternative prototypes (i.e. moderate drinker) into the relationship between prototype perceptions and drinking behaviour. The results suggest tailoring prototype-based interventions according to drinking behaviour. Importantly, realistic perceived similarity to the more favourable moderate drinker prototype may therefore need to be encouraged only after appropriate reductions in heavy drinkers’ alcohol consumption.     

Causal explanations for lack of pregnancy applying the common sense model of illness representation to the fertility context

Abstract

Objectives: The current study explored causal explanations for lack of pregnancy and association with help-seeking behaviour. Differences based on gender and country Human Development Index were examined.

Design: A mixed method design was used.

Main outcome measures: Data were drawn from the International Fertility Decision-Making Study, a cross-sectional study of 10,045 individuals (1690 men; 8355 women) from 79 countries. Respondents rated to what extent they believed their lack of pregnancy was due to something they or their partner had done/not done or other factors and described their reasons for making this rating.

Results: Respondents were aged 18–50 (M?=?31.83) years, partnered and had been trying to achieve a pregnancy/father a child for over six months (M?=?2.8 years). Men and women primarily believed their lack of pregnancy was due to medical problems or chance/bad luck. Thematic analysis of textual responses from 29.7% of the sample found that respondents focused on their personal experience or a salient life event when describing the cause of their lack of pregnancy. Women expressed more regret and helplessness about causes than men. Significant country differences were observed.

Conclusions: Individuals may develop inaccurate causal explanations based on their personal experiences. Access to accurate information is necessary to facilitate timely help-seeking.     

Quantifying age-related differences in selective voluntary motor control in children and adolescents with three assessments

BackgroundNeurophysiological development of selective voluntary motor control (SVMC) is assumed but has not been quantified objectively. We assessed SVMC with (i) clinical assessments, (ii) a combination of these assessments with surface electromyography (sEMG) and, (iii) a playful computer game. The aim of this study was to describe and compare age-related differences in SVMC, quantified with these tools, in neurologically intact children, adolescents, and adults.MethodsWe measured upper and lower extremity SVMC with three assessments in 31 children and adolescents. A sample of 33 and 31 adults provided reference values for the upper and lower extremity assessments, respectively. The Selective Control of the Upper Extremity Scale (SCUES) or the Selective Control Assessment of the Lower Extremity (SCALE) were combined with simultaneous sEMG recordings. We quantified SVMC by a similarity index that compared an individual's muscle activation pattern with those of an adult reference group. The SVMC Assessgame required isolated joint movements to steer an avatar and quantified the accuracy of the selective movement and the extent of involuntary movements occurring in not involved joints.ResultsResults from the conventional clinical assessments correlated low to moderately with age (SCUES: r = 0.55, p = 0.013; SCALE: r = 0.44, p = 0.001), while the correlation between the sEMG based similarity index and age was negligible (r ≤ 0.25). The outcomes of the Assessgame correlated highly with age (r ≥ 0.80, p ≤ 0.001). Older children and adolescents performed movements more accurately and with fewer involuntary movements compared to younger participants.ConclusionsThe tools assess and quantify SVMC differently, affecting the way they capture age-related differences in SVMC. Some assessments require reference values from neurologically intact children and adolescents to correctly classify impairments of SVMC in patients with neuromotor disorders.     

Evaluating dynamic similarity of fixed,self-selected and anatomically scaled speeds in non-linear analysis of gait during treadmill running

ObjectivesThe aim of this study is to evaluate how speed affects non-linear measures of variability. Fixed and self-selected speeds were compared to an anatomically scaled speed calculated based on leg length to evaluate which provided a more reproducible result between subjects.MethodsSixteen subjects ran on a treadmill at a fixed, scaled and self-selected speed and at ±10% in each case. Kinematic data were collected for two minutes at 250 Hz for each trial. Sample entropy (SaEn) and maximum Lyapunov exponents (LyE) were calculated from the sagittal knee and hip joint angles to evaluate regularity of gait and local stability. These nonlinear measures were compared to evaluate the dynamic similarity of the movement in each case, and to evaluate speed as a confounding variable in non-linear analysis.ResultsAn anatomically scaled speed shows more dynamic similarity than a fixed or self-selected speed with the lowest observed coefficient of variation for each measure. This was found to be statistically significant for both nonlinear measures of the hip (SaEn p = 0.038; LyE p = 0.040). Speed was not found to be a confounding variable in non-linear analysis of running gait of a healthy population (η² < 0.05).ConclusionsChanges in speed by ±10% do not significantly affect stability and variability of gait for healthy participants, suggesting that they make adaptations to ensure optimal gait variability.Anatomically scaled speeds provide a more reliable methodology for both linear and non-linear analysis by providing a definitive protocol, suggesting it could replace self-selected or fixed speeds in future research.     

Correlates of Team Success in Higher Education

Summary

An attitude questionnaire was filled out by 75 undergraduates who subsequently evaluated a hypothetical male convict's responses to the same survey—the convict's attitudes being either 10% or 90% similar to each S's own views. Ss then made judgments of the convict's emotional maturity, sense of personal responsibility, and control of violent impulses, as well as how much they would like him as a person and how willing they would be to recommend him for parole. The results indicated that attitudinal similarity to the convict was associated with significantly more positive evaluations of him on each of the five response measures. It was suggested that attitudinal similarity to a convict could be a biasing factor in judgments of whether or not the convict should be paroled.     

Value Perceptions in Leader-Member Exchange

Abstract

In a simulation study, I examined the potential role of values in leader-member exchanges (Dansereau, Graen, & Haga, 1975). Little research has been conducted to determine the factors influential in the development of leadership versus supervisory exchanges (Dienesch & Liden, 1986). In this study, greater similarity between supervisor and subordinate values was perceived in leadership exchanges. The study was conducted in France and the United States. No support was gained for the hypothesis that similarity would be less important in France. The results did suggest greater individualism among American subjects and more conformity among French subjects.     

Practicum of Group Psychotherapy

Abstract

Many studies on therapeutic factors in group psychotherapy were done during the 1970s and 1980s, primarily with Western samples. The present study was carried out in a psychiatric inpatient clinic in Turkey. Using Yalom’s (1975) therapeutic factor questionnaire administered at discharge, patients rated existential factor, instillation of hope and self–understanding as the most helpful factors and identification as the least helpful. There were significant differences among patients with regard to gender, age, education, and comorbid personality disorder, but not with Axis I diagnosis or number of attended sessions. Patients’ and psychiatrist’s ratings showed significant differences. Differences between this Turkish sample and those reported in common Western literature are discussed under the light of relatedness psychology, which is an important concept of cross–cultural psychology.     

Learning by explaining: Impacts of explanations on the development of a competence

IntroductionPrevious research has mainly studied the impact of activity explanation on performances (e.g., Chi, 2009), but little research has been done to examine its impact on the development of a competence.ObjectiveA model of dynamic analysis of competence (Coulet, 2011) has been used to measure the impact of activity explanation on the development of a technical competence.MethodExplanation of tasks of varying complexity has been manipulated in two experimental studies; effects of activity explanation have been measured on objective performance, perceptions related to the task and final explanations.ResultsParticipants who explained their activity not only performed better on the tasks, but also showed more positive perceptions of their relations to the task and a better ability to produce didactic explanations.ConclusionPsychological processes involved in explaining activity and their implications are examined and discussed.     

In Defence of Kripkenstein: On Lewis’ Proposed Solution to the Sceptical Argument

Abstract

In Wittgenstein: On Rules and Private Language, Saul Kripke argues for an extreme form of meaning scepticism. One influential reply to Kripke’s arguments was developed by David Lewis. The reply developed by Lewis makes use of the notion of mind-independent relations of similarity and difference. The aim of the paper is to argue that Lewis’ reply is not satisfactory: the challenge to find a refutation of Kripke’s sceptical arguments remains unmet.     

Effect of Method,Instructions, and Age on Stimulus “preference” Assessments

Summary

Two experiments were conducted to examine whether two types of cue preference assessment procedures involve different response processes. In Experiment 1, children were administered a Matching-to-Sample dimensional preference test and a two-stimulus preference test. The results indicated that only about half of the children chose the same cue consistently in either task, and only a few children chose the same cue in both preference tests. That these results were, in part, a result of Matching-to-Sample instructions that eliminated the set to match stimuli on the basis of perceived similarity was demonstrated in Experiment 2. Only when the children were instructed to make similarity judgments did they choose consistently in a Matching-to-Sample preference test. When they were not so instructed, only those children with strong attentional habits (who were few in number) chose the same cue consistently.     

Similarity judgments of same-category object representations: Effects of physical size,manipulability, and word frequency

ABSTRACT

Studies of object similarity have focused on the relationship between different physical objects and their mental representations or between instances of the same physical object and its mental representation. The present study is the first to investigate the structure of within-category psychological space. We provided evidence that large objects and frequently mentioned objects are perceived as less similar to each other compared to small objects or less frequently mentioned objects. Further, similarity judgments were higher for manipulable objects compared to non-manipulable objects. The relevance of these data to the isomorphism between physical and psychological spaces is also discussed.     

Predicting sports performance from well-being: A mapping of professional athletes’, amateur athletes’ and non-athletes’ positions

IntroductionPrediction of performance and well-being are two essential keys in sports performance.ObjectiveThe study aimed to map different positions regarding the way in which individuals integrated mentally five elements of eudaimonic well-being (relatedness, autonomy, competence, mental vitality and physical vitality) for predicting the degree of performance at the beginning of a match.MethodTwenty-four non-athletes, 44 amateur athletes and 26 professional athletes indicated their prediction of performance in 32 scenarios constructed from the combination of these elements of well-being. Cluster analysis, ANOVAs, and chi-square test have been done.ResultsTwo positions on prediction of performance were found. The first cluster was called “Sometimes Performance Prediction” and the second cluster was named “Seldom Performance Prediction”. The five elements had a positive effect on the prediction of performance. The composition of both clusters was linked to the level of involvement in sport.ConclusionOffering athletes a “well-being environment” may lead to predict the sports performance.     

Plain Semi-Post algebras as a poset-based generalization of post algebras and their representability

Semi-Post algebras of any type T being a poset have been introduced and investigated in [CR87a], [CR87b]. Plain Semi-Post algebras are in this paper singled out among semi-Post algebras because of their simplicity, greatest similarity with Post algebras as well as their importance in logics for approximation reasoning ([Ra87a], [Ra87b], [RaEp87]). They are pseudo-Boolean algebras generated in a sense by corresponding Boolean algebras and a poset T. Every element has a unique descending representation by means of elements in a corresponding Boolean algebra and primitive Post constants which form a poset T. An axiomatization and another characterization, subalgebras, homomorphisms, congruences determined by special filters and a representability theory of these algebras, connected with that for Boolean algebras, are the subject of this paper.To the memory of Jerzy SupeckiResearch reported here has been supported by Polish Government Grant CPBP 01.01
