A multidimensional scaling analysis of own- and cross-race face spaces

We examined predictions derived from Valentine’s (1991) Multidimensional Space (MDS) framework for own- and other-race face processing. A set of 20 computerized faces was generated from a single prototype. Each face was saved as Black and White, changing only skin tone, such that structurally identical faces were represented in both race categories. Participants made speeded “same-different” judgments to all possible combinations of faces, from which we generated psychological spaces, with “different” RTs as the measure of similarity. Consistent with the MDS framework, all faces were pseudo-normally distributed around the (unseen) prototype. The distribution of faces was consistent with Valentine’s (1991) predictions: despite their physical identity to the White faces, Black faces had lower mean inter-object distances in psychological space. Other-race faces are more densely clustered in psychological space, which could underlie well-known recognition deficits.     

Predicting raters’ transparency judgments of English and Chinese morphological constituents using latent semantic analysis

The morphological constituents of English compounds (e.g., “butter” and “fly” for “butterfly”) and two-character Chinese compounds may differ in meaning from the whole word. Subjective differences and ambiguity of transparency make judgments difficult, and a computational alternative based on a general model might be a way to average across subjective differences. In the present study, we propose two approaches based on latent semantic analysis (Landauer & Dumais in Psychological Review 104:211–240, 1997): Model 1 compares the semantic similarity between a compound word and each of its constituents, and Model 2 derives the dominant meaning of a constituent from a clustering analysis of morphological family members (e.g., “butterfingers” or “buttermilk” for “butter”). The proposed models successfully predicted participants’ transparency ratings, and we recommend that experimenters use Model 1 for English compounds and Model 2 for Chinese compounds, on the basis of differences in raters’ morphological processing in the different writing systems. The dominance of lexical meaning, semantic transparency, and the average similarity between all pairs within a morphological family are provided, and practical applications for future studies are discussed.     

Situational Determinants of Personal Validation of General Personality Interpretations

Groups of Ss were matched with respect to their pre-experimental opinions regarding the value of psychological tests used by trained professionals to describe personality. Ss were then given either the Rorschach, TAT, FIRO-B, or Marlowe-Crowne Social Desirability Scale and were later given identical general personality interpretations supposedly based on the test results. An analysis of variance of Ss ratings of the accuracy of the personality interpretation indicated that neither the type of test S took nor whether the personality interpretation was presented as being derived “for you specifically” or “for people in general” had differential effects on Ss' acceptance of the interpretation; all groups rated the interpretation as being between “good” and “excellent.”     

Implications for interaction versus effectance as mediators of the similarity-attraction relationship

The rewards of interaction interpretation of the similarity-attraction relationship implies that this relationship should be stronger when similarity has stronger implications for the quality of interaction. In contrast, the reinforcement-affect (D. Byrne & G. L. Clore, Journal of Personality and Social Psychology 1967, 6(Whole No. 638)) interpretation suggests that similarity should affect attraction most for characteristics that are most “important” to the perceiver. Three experiments tested these predictions. In Experiments 1 and 2, subjects rated eight strangers who were similar or dissimilar with respect to four opinion categories. With item importance held constant, the magnitude of the similarity-attraction relationship was greater for opinion categories with greater implications for interaction. In Experiment 3, item sets were constructed using subjects' own ratings of item importance and of amount of information conveyed about interaction. The magnitude of the similarity-attraction relationship was significantly related to the interaction ratings of item sets, but not to their importance ratings. The meaning of the concept of item “importance”, and the potential of the rewards of interaction formulation for generation of research are discussed.     

Cree Conceptions of Cognitive Competence

The study of cognitive competence in various cultures has shifted from examining “general intelligence” (very often only in terms known to Western cultures), to a concern for indigenous conceptions of what it means to be a capable person in that culture. Ethnographic techniques elicited the range of Cree terms for such general competence. With a sample of 60 Cree adults in Northern Ontario (stratified by age and sex), we obtained card sorts for 20 terms (piles sorted on basis of similarity), and semantic differential ratings (on 12 bipolar adjective dimensions), for two of the terms. A two-dimensional solution was obtained using Multidimensional scaling. On one dimension there was a cluster of core terms (e.g. wise, thinks hard, pays attention, respectful, good sense of direction) at one end, and three other terms (stupid, crazy, “backwards knowledge”) at the other. On the second dimension, a pair of terms translated as “mentally tough” (with implications of perseverance, stamina, bravery) was at one end, and two other terms (understands new things, religious) were at the other. The term for “lives like a white person” was opposite the core cluster of terms for Cree competence. Ratings of the two terms (“wise” and “understands new things”), indicate that both are associated with: Taking time, good, hard-working, careful, patient, self-sufficient, strong, developing, bush-related, and easy to see. These results indicate some clear differences from Western notions of intelligence as being fast, analytic and without social or moral dimensions.     

The coincidence effect in similarity and choice

Medin, Goldstone, and Markman (1995) recently described a series of parallel effects in similarity and choice. They suggested that similarity and choice are related in a nontrivial way such that choice may entail a similarity judgment to an explicit or constructed ideal. In this paper, the correspondences between similarity and choice were investigated with respect to a phenomenon in similarity known as thecoincidence effect. In coincidence (pronounced “coincide-ence”), two items that match on one dimension but have a large difference on another dimension receive a higher similarity rating than do two items that have only modest differences on both dimensions. We conducted five experiments in order to examine commonalities between similarity and choice processes with respect to coincidence. Four types of tasks were given: similarity ratings, desirability ratings, forced choice similarities (which of two items is most similar to a target), and forced choice preferences (which of two items one would prefer, given a target). We found a main effect for ratings as opposed to forced choices, with ratings showing greater coincidence effects than did choices. Similarity measures tended to produce more coincidence than did preference measures. The overall pattern of results suggests the presence of dimensional weighting processes sensitive to task characteristics and operating somewhat differently for similarity and decision making.     

Situational constraint and type of causal explanation: The effects on perceived “mental illness” and social rejection

The present study investigated the effects of situational constraint and type of causal explanation on the degree to which described behavior would be perceived as evidencing “mental illness” and the degree to which it would lead to social rejection.Results showed that both of these variables influenced the degree of attributed “mental illness”, the degree of attributed psychological disturbance, and the degree of social rejection. Behavior inappropriate to a situation was rated higher on all three of these variables. Behavior attributed to external pressures received lower ratings on these variables than that attributed to internal causes, to organic causes, or for which no apparent explanation was available.     

Mapping the similarity space of paintings: Image statistics and visual perception

What makes two images look similar? Here we test the hypothesis that perceived similarity of artwork is related to basic image statistics to which the early visual system is attuned. In two experiments, we employ multidimensional scaling (MDS) analysis of paired-image similarity ratings from observers for paintings. Two sets of images, classified as “landscapes” and “portraits/still-life”, are tested separately. For the landscapes, we find that one of the first two MDS scales of similarity is strongly correlated with a basic greyscale image statistic, whereas the other dimension can be accounted for by a semantic variable (representation of people). For portrait/still-life, the first two MDS scales of similarity are most highly correlated with semantic variables. Linear combinations of statistical and nonstatistical features achieve improved predictive values for the first two MDS scales for both sets. The statistics that play the largest role in shaping similarity judgements in our tests are the activity fraction measure of sparseness and the log-log slope of the spatial frequency amplitude spectrum. We discuss these results in the context of scene perception and in terms of efficient coding of statistical regularities in scenes.     

Interal locus of control as a value

Internal and external subjects, who previously filled out Rotter's (1966) I-E scale, were asked to score the I-E scale of “another student”. Subjects were exposed to “an other's” score of either 0, 5, 10, 16, or 23, and were asked to rate themselves and the “other” on an evaluative questionnaire. It was predicted that ratings of the “other” would increase in positivity to the extent the “other” scored as an internal. A reverse direction was predicted for an index of negative evaluations. The predictions were confirmed. The results suggest that internal locus of control is a societal value. The findings did not support either Hannah's (1973) hypothesis that internals are more responsive to a need for social approval, or Byrne's (1969) similarity hypothesis.     

Are supervisors and coworkers likely to witness employee counterproductive work behavior? An investigation of observability and self–observer convergence

Supervisor and coworker ratings (i.e., “observer ratings”) remain a common manner of measuring counterproductive work behavior (CWB) despite long‐standing doubts that observers have the opportunity to witness the work behaviors they are expected to rate. We conducted 2 studies that evaluated the observability of CWB items and consequences of observability. First, we show that many CWBs are unlikely to be witnessed by supervisors or coworkers—specifically, behaviors such as “spends too much time fantasizing or daydreaming instead of working” and “discussed confidential company information with an unauthorized person” were found to be lowest in observability, whereas “cursed at someone at work” or “acted rudely toward someone at work” were relatively higher in observability (though observability was generally low). Second, a meta‐analysis revealed variability in item‐level relationships (correlations and mean differences) between self‐ratings and observer ratings for specific CWB scale items (i.e., items from Bennett & Robinson, 2,000). Important, this variability was partially explained by observability—behaviors with low self–observer convergence tend to have low levels of observability, whereas behaviors with higher levels of convergence tend to have higher levels of observability. This study demonstrates that supervisor and coworker ratings of CWB may be susceptible to an observability bias resulting from rating behaviors they have not likely witnessed.     

Students' ratings of occupational dimensions of traditionally male and traditionally female occupations

The purpose of the present study was to investigate four traditionally male occupations and four traditionally female occupations on a number of dimensions which people use to judge the prestige or importance of a job. Workers were pictured on one form in their traditional roles and on a second form in nontraditional roles. Results indicated a tendency for subjects to give lower ratings to workers in nontraditional jobs. More importantly, for the two “objective” dimensions, money and education, boys and girls agreed on job ratings; however, on the two more “subjective” dimensions, respect and importance to the community, boys gave higher ratings to the male jobs, while girls gave higher ratings to the female jobs.     

Al-Ghazali's Use of the Terms “Necessity” and “Habit” in his Theory of Natural Causality

The present article aims at analyzing the terms “necessity” (Al-darura) and “habit” (al-āda) in al-Ghazali's (1058?–?1111) theory of natural causality (Al-Sbābiah al-Tabī'īa) by answering the following question: Why does Al-Ghazali use term “habit” and negation of “necessity” with regard to natural Causality? Al-Ghazali denies causal necessity that links cause and effect since this relationship does not draw on logical rules that make it necessary. This, however, does not mean that he denies the existence of a causal relationship between things, as he recognizes its existence. He, however, denies the necessity of that relationship, as he claims that the source of causal necessity stems from a psychological emotion rather than from being inherent in things themselves. Al-Ghazali also attempts to base causal necessity on “habit” by claiming that the similarity of event A as cause and event B as effect stems from observation, repetition and the sequencing of natural phenomena. Al-Ghazali, then, endeavors to prove that science is based on expectation and assumption that draws on observation, the senses, and repetition and does not consider it as constant and absolute.     

An analysis of generative representation systems

Three ideas are basic to generative theory: (a) Subjects are assumed to attend to the relations among stimuli, extracting the transformations relating pairs of stimuli; (b) the set of abstracted transformations is decomposed or reduced to an elementary set of generators; (c) subjects use the elementary generators as the basis for judging similarity. The purpose of this paper is to illustrate these ideas with an experiment in which subjects were asked to rate the similarity between stimulus pairs. The stimulus materials consisted of the permutations of a 4-item pattern with the properties of a dihedral group which insured the existence of sets of elementary transformations. Three analytic techniques were used to determine the generator set of transformations abstracted by subjects. The first analysis consisted of a monotonic regression between dissimilarity ratings and the number of elementary generators of a given permutation. The residual variance of this monotone regression, suitably normalized, was used as a quantitative goodness-of-fit measure. For the stochastic analysis, cumulative distributions of dissimilarity ratings were obtained for permutations requiring one, two, or three generators. The idea was that permutations requiring fewer generators should be associated with distributions of lower dissimilarity values (higher similarity scores) as compared to permutations predicted to be transformationally more complex. The final analysis, a multidimensional scaling of dissimilarity ratings, converted subjects' ratings into spatial structures to determine whether individual subjects' ratings exhibited the predicted spatial arrangement. The monotone regression and stochastic analyses abstracted similar generator sets for individual subjects, some of which provided perfect fits to the data. Although the scaling analysis yielded similar estimates of generators, for some subjects, transformations with the same number of generators yielded unequal “cognitive” distances resulting in some-what deformed spatial structures for these subjects. It was concluded that the results generally supported a generative model as an approximation to subjects' representations of interstimulus relationships.     

Shared Meaning and the Convergence among Observers' Personality Descriptions

ABSTRACT “Shared meaning” is a parameter in Kenny's (1991) rater agreement model concerning the extent to which two raters agree about the trait-implicative meaning of the observations they have made of a target. In the first study, 201 individuals rated observations relevant to friendliness and organization on the meaning dimensions of typicality, difficulty level, and evaluation. They also rated 25 targets on the two constructs. We found strong support for a modest relation between the similarity of meaning ratings and the similarity of target ratings, especially for raw, as opposed to standard score, ratings. In Study 2 we considered shared meaning in a version of Kenny's model that included the consistency and communication parameters. Judge pairs (N= 110) evaluated two targets described by play and openness on several personality dimensions. Shared meaning significantly contributed to rating agreement for both targets, but consistency and communication, as manipulated in this study, did not. Implications of employing the broader consensus model in experimental studies are discussed. If I say “sorrow,” you'll know exactly what I mean only if you've experienced it in the same sense I have. -Joel Peterson, Ravenswood's Winemaker, in Darlington (1991)     

Stimulus Parameters Underlying Sound-Symbolic Mapping of Auditory Pseudowords to Visual Shapes

Sound symbolism refers to non-arbitrary mappings between the sounds of words and their meanings and is often studied by pairing auditory pseudowords such as “maluma” and “takete” with rounded and pointed visual shapes, respectively. However, it is unclear what auditory properties of pseudowords contribute to their perception as rounded or pointed. Here, we compared perceptual ratings of the roundedness/pointedness of large sets of pseudowords and shapes to their acoustic and visual properties using a novel application of representational similarity analysis (RSA). Representational dissimilarity matrices (RDMs) of the auditory and visual ratings of roundedness/pointedness were significantly correlated crossmodally. The auditory perceptual RDM correlated significantly with RDMs of spectral tilt, the temporal fast Fourier transform (FFT), and the speech envelope. Conventional correlational analyses showed that ratings of pseudowords transitioned from rounded to pointed as vocal roughness (as measured by the harmonics-to-noise ratio, pulse number, fraction of unvoiced frames, mean autocorrelation, shimmer, and jitter) increased. The visual perceptual RDM correlated significantly with RDMs of global indices of visual shape (the simple matching coefficient, image silhouette, image outlines, and Jaccard distance). Crossmodally, the RDMs of the auditory spectral parameters correlated weakly but significantly with those of the global indices of visual shape. Our work establishes the utility of RSA for analysis of large stimulus sets and offers novel insights into the stimulus parameters underlying sound symbolism, showing that sound-to-shape mapping is driven by acoustic properties of pseudowords and suggesting audiovisual cross-modal correspondence as a basis for language users' sensitivity to this type of sound symbolism.     

Concepts of Creativity: Similarities and Differences among Mainland,Hong Kong and Taiwanese Chinese

Aspects of creativity concepts across different Chinese populations were examined. A Likert style questionnaire consisting of 60 adjectives was administered to 451 undergraduates from Beijing, Guangzhou, Taipei and Hong Kong. The results show that: (a) the core characteristics of creativity identical in all the samples are: “originality”, “innovativeness”, “thinking” and “observational skills”, “flexibility”, “willingness to try”, “self confidence”, and “imagination”; (b) the Taipei sample, unlike the other three samples, does not associate “wisdom”, “assertiveness”, and “individualism” with creativity; (c) in all Chinese populations the three factors labeled innovative, dynamic, and intellectual were distinguishable in the concept of creativity; (d) “artistic” and “humorous” were missing in the Chinese perception of creativity; (e) creativity characteristics received relatively low ratings on the desirability scale.     

Boys Don’t Work? On the Psychological Benefits of Showing Low Effort in High School

Male students show less academic effort and lower academic achievement than do female students. The present study aimed to shed more light on the reasons for why male students show low academic effort despite the finding that this undermines their academic achievement. We explored whether students experience psychological benefits from showing low effort or “effortless” achievement in school and whether these benefits are greater for male than for female students. In two experimental vignette studies with independent samples of German ninth graders (N?=?210) and teachers (N?=?176), we systematically varied student targets’ gender, effort, and achievement and tested for effects on targets’ ascribed intelligence, popularity, likeability, masculinity, femininity, and gender-typicality. The “effortless” achiever was rated as more popular than students showing high effort. Teachers perceived the effortless achiever as the most intelligent target. Academic effort further increased students’ ratings of a low-achieving target’s likeability and students’ and teachers’ ratings of all targets’ femininity as well as decreased students’ ratings of all targets’ masculinity. Students and teachers perceived targets showing low (vs. high) effort as more similar to a typical boy, whereas teachers perceived targets showing high (vs. low) effort as more similar to a typical girl. Results indicate a need to understand the psychological benefits of low academic engagement, especially for male students, and to address the feminine stereotyping of (academic) effort.     

Health and Well-Being in Highly Cohesive Units of the U.S. Army1

A large civilian literature on the role of social support in health and well-being suggests that military units high in unit cohesion should provide their members both significant protection from physical and mental illness and high levels of job satisfaction. This hypothesis was tested with a questionnaire survey of soldiers in Special Forces “A-teams”, generally viewed as the U.S. Army's most cohesive permanent units. As predicted, A-team soldiers reported greater physical and psychological well-being and greater satisfaction with job and career than did soldiers in conventionally organized units, be they Special Forces, airborne, or mechanized infantry. The best predictors in our battery of demographic, personality, and cohesion measures were ratings of social support from and satisfaction with one's Army unit, and relatively more “internal” scores on the Rotter locus-of-control scale. From these data and extensive participant observation we conclude that unit cohesion provides the soldier considerable protection from the stresses of military life, even in peace, and that it is organizational rather than individual variables that are primarily responsible for the very high levels of cohesion and/or social support in Special Forces A-teams.     

“Just another pretty face”: A multidimensional scaling approach to face attractiveness and variability

Findings on both attractiveness and memory for faces suggest that people should perceive more similarity among attractive than among unattractive faces. A multidimensional scaling approach was used to test this hypothesis in two studies. In Study 1, we derived a psychological face space from similarity ratings of attractive and unattractive Caucasian female faces. In Study 2, we derived a face space for attractive and unattractive male faces of Caucasians and non-Caucasians. Both studies confirm that attractive faces are indeed more tightly clustered than unattractive faces in people’s psychological face spaces. These studies provide direct and original support for theoretical assumptions previously made in the face space and face memory literatures.     

The Witness Credibility Scale: An outcome measure for expert witness research

The judge or jury makes a subjective determination of when an expert is credible. However, no published measure exists for assessment of the credibility of expert witnesses. The current study addressed this gap by developing and cross‐validating the Witness Credibility Scale (WCS). Drawing on the narrative literature, we hypothesized that credibility was a product of four factors: “likeability,” “believability,” “trustworthiness,” and “intelligence.” A 41‐item measure was initially constructed based on successive iterations of ratings by a panel of judges using items from the Osgood Semantic Differential measure and was subsequently administered to 264 undergraduates. A factor analysis of the data yielded a factor structure that consisted of four factors labeled, “knowledge,” “likeability,” “trustworthiness,” and “confidence.” The final version of the WCS used 20 adjectives with four subscales of five items, each subscale reflecting high loadings on the respective factors. The scale was then tested in five additional studies, in which the scale successfully differentiated between groups of videotaped experts testifying in manipulated conditions. The empirical data from these studies permit a foundation for comparing outcome data in future research investigations. Copyright © 2010 John Wiley & Sons, Ltd.
