The vocal attractiveness stereotype: Replication and elaboration

We examined personality impressions on five NEO subscales (Costa & McCrae, 1985) as a function of senders' vocal and physical attractiveness. There were four major findings: (a) both vocal and physical attractiveness produced more favorable ratings, and these effects were more pronounced in a single channel (voice only or face only, respectively) than in a multiple channel (voice plus face); (b) the influence of attractiveness, both vocal and physical, was moderated by subscale—the effect of vocal attractiveness was most pronounced for Neuroticism and nonexistent for Agreeableness; the effect of physical attractiveness was most pronounced for Extraversion and nonexistent for Conscientiousness; (c) a vocal attractiveness × physical attractiveness interaction indicated that effects of the two stereotypes were particularly strong for senders who were attractive on both channels; (d) the effects of attractiveness, both vocal and physical, diminished when judges were familiar with the target persons.This research was supported in part by National Institute of Mental Health Grant RO1 MH 40498.     

The attractive voice: What makes it so?

Previous research has shown that more attractive voices are associated with more favorable personality impressions. The present study examined which acoustic characteristics make a voice attractive. Segments of recorded voices were rated on various dimensions of voice quality, attractiveness, and personality impressions. Objective measures of voice quality were obtained from spectrogram analysis. Overall, the subjective ratings of voice quality predicted vocal attractiveness better than the objective measures. When vocal attractiveness was regressed onto both subjective and objective measures, the final regression equation included 8 subjective measures, which together accounted for 74% of the variance of the attractiveness scores. It also was found that the measures of voice quality accounted for variance in favorableness of personality impressions above and beyond the contribution of vocal attractiveness. Thus, attractiveness captures an important dimension of the voice but does not cover all aspects of voice quality.This research was supported by National Institute of Mental Health Grant MH40498.     

When Physical and Vocal Attractiveness Differ: Effects on Favorability of Interpersonal Impressions

Previous research has shown that targets whose physical and vocal attractiveness do not match (one channel being high and the other being low in attractiveness) elicit more negative impressions. The present study replicated this result and showed that the mediator and, hence, the reason for this effect is not simply a perception that the face and voice are discrepant but rather some disappointment with the less attractive channel. The finding that perceivers are overly disappointed with the less attractive channel is consistent with a large literature indicating that effects of negative events such as unattractive face or voice are stronger than effects of positive events.     

The Provider’s Voice: Patient Satisfaction and the Content-filtered Speech of Nurses and Physicians in Primary Medical Care

Two studies examined vocal affect in medical providers’ and patients’ content-filtered (CF) speech. A digital methodology for content-filtering and a set of reliable global affect rating scales for CF voice were developed. In Study 1, ratings of affect in physicians’ CF voice correlated with patients’ satisfaction, perceptions of choice/control, medication adherence, mental and physical health, and physicians’ satisfaction. In Study 2, ratings of affect in the CF voices of physicians and nurses correlated with their patients’ satisfaction, and the CF voices of nurses and patients reflected their satisfaction. Voice tone ratings of providers and patients were intercorrelated, suggesting reciprocity in their vocal affective communication.     

Nonverbal behavior and gender as determinants of physical attractiveness

We investigated the combined and interacting effects of positivity, dominance, sex, and three nonverbal channels on the perception of physical attractiveness. We found that positive affects were rated as more attractive than negative affects regardless of the channel (face and voice, as well as body). We also found that physical attractiveness in females appeared to be a function of the face and body combined, whereas for males it appeared more to be a function of the face alone.Preparation of this paper was supported in part by the National Science Foundation and by the Spencer Foundation.

Parent and Nonparent Perception of the Multimodal Infant Cry

This study examined whether perceivers can detect infant distress in the visual and acoustic signals within the cry. Parent and nonparent perceivers rated distress in 3‐, 6‐, 8‐, and 12‐month‐old infants' cries that were manipulated to separate facial, vocal, and bodily action. Mean perceiver ratings differed for high‐ and low‐distress cries at each infant age on the basis of facial and vocal action, but not bodily movement. Perceivers rated the cry sound as more distressed and the cry face as less distressed with increasing infant age. Parents rated the cries as less distressed overall than did nonparents. The results suggest that information about distress is available for perceivers in the crying infant's face and voice.     

Vocal and Physiological Changes in Response to the Physical Attractiveness of Conversational Partners

We examined how individuals may change their voices when speaking to attractive versus unattractive individuals, and if it were possible for others to perceive these vocal changes. In addition, we examined if any concurrent physiological effects occurred when speaking with individuals who varied in physical attractiveness. We found that both sexes used a lower-pitched voice and showed a higher level of physiological arousal when speaking to the more attractive, opposite-sex target. Furthermore, independent raters evaluated the voice samples directed toward the attractive target (versus the unattractive target) as sounding more pleasant when the two voice samples from the same person presented had a reasonably perceptually noticeable difference in pitch. These findings may have implications for the role voice plays in mate selection and attraction.     

The Perception and Parameters of Intentional Voice Manipulation

Evidence suggests that people can manipulate their vocal intonations to convey a host of emotional, trait, and situational images. We asked 40 participants (20 men and 20 women) to intentionally manipulate the sound of their voices in order to portray four traits: attractiveness, confidence, dominance, and intelligence to compare these samples to their normal speech. We then asked independent raters of the same- and opposite-sex to assess the degree to which each voice sample projected the given trait. Women’s manipulated voices were judged as sounding more attractive than their normal voices, but this was not the case for men. In contrast, men’s manipulated voices were rated by women as sounding more confident than their normal speech, but this did not hold true for women’s voices. Further, women were able to manipulate their voices to sound just as dominant as the men’s manipulated voices, and both sexes were able to modify their voices to sound more intelligent than their normal voice. We also assessed all voice samples objectively using spectrogram analyses and several vocal patterns emerged for each trait; among them we found that when trying to sound sexy/attractive, both sexes slowed their speech and women lowered their pitch and had greater vocal hoarseness. Both sexes raised their pitch and spoke louder to sound dominant and women had less vocal hoarseness. These findings are discussed using an evolutionary perspective and implicate voice modification as an important, deliberate aspect of communication, especially in the realm of mate selection and competition.     

Vocal types and stereotypes: Joint effects of vocal attractiveness and vocal maturity on person perception

Subjects rated the power, competence, warmth, and honesty of stimulus persons whose voices systematically and independently varied along the dimensions of vocal attractiveness and vocal maturity. The results revealed that the effects of vocal attractiveness on person perception can be attenuated or augmented by variations in vocal maturity; and that the effects of vocal maturity on impressions can be similarly modified by level of attractiveness. Implications of the data for the understanding of vocal stereotypes are discussed.     

Mein(schöner)Prof.de

Evaluations of academic teaching have become an instrument for the quality management in universities of constantly growing importance. This process is unproblematic as long as the quality of teaching is rated validly by the evaluations of students. The validity of the rating, however, becomes questionable as an influence of the teaching staffs’ physical attractiveness on the evaluation of teaching has been proved. This effect would only be compatible with an assumed valid rating of the teaching performance if attractive teachers would in fact show a better performance in academic teaching and are not just better rated for their attractiveness. We analyzed data from the German online platform MeinProf.de for the evaluation of academic teachers. The results show that attractive teachers very probably do not perform better. The attractiveness of female teachers does not have the expected influence on the evaluation of their teaching.     

Listening to Voices and Judging People

The impact of vocal cues on personality judgments is investigated in an experimental study that used technically manipulated levels of pitch (low and high frequency), sex of the speaker, and content area (e.g., fixing a bike, baking, reading directory information) as independent and the entailing personality judgments as dependent variables. Subjects (48 male and 48 female) were presented with voice probes and ratings of physical (age, sex, height, stature), and psychological characteristics (bipolar adjectives representing the “Big Five” dimensions of personality) were collected. Results confirm that voice characteristics have an impact on interpersonal perception and that vocal cues are processed separately by the listener. Results are discussed with reference to processing demands and cognitive load on the working memory of a listener.     

Shame,Sexual Compulsivity,and Eroticizing Flirtatious Others: An Experimental Study

Clinical observation and correlational studies with nonclinical samples suggest that a linkage between negative affective states (especially shame) and engagement in erotic pursuits typifies sexual compulsivity. The present study tested whether experimental induction of shame leads to increased interest in erotically suggestive targets among more sexually compulsive individuals. A total of 74 age-traditional heterosexual university students first recalled either an emotionally neutral or a shame-inducing personal experience, then completed a nonpredictive gaze-cueing task featuring flirtatious or emotionally neutral faces of the same or opposite sex. They also rated the faces’ attractiveness and completed a validated sexual compulsivity scale and two control measures (executive control, sociosexuality). Higher (versus lower) sexual compulsivity predicted weaker gaze-triggered attentional orienting in response to the flirtatious opposite-sex face in the shame (versus neutral) condition, and this was accounted for by (higher) attractiveness ratings of the flirtatious opposite-sex face. Shame thus appears to increase sexualization (i.e., reduces salience of agentic features and increases appeal of physical attributes) of erotically suggestive targets among more sexually compulsive individuals.     

The Effects of Average Fundamental Frequency and Variance of Fundamental Frequency on Male Vocal Attractiveness to Women

This paper employs a cue synthesis experimental method to examine the effects of pitch and intonation on male vocal attractiveness to women. Voices were acoustically manipulated to yield nine combinations of three levels of average fundamental frequency and three levels of variance of fundamental frequency. Strong main effects were obtained for the average fundamental frequency manipulation, with high voices rated as significantly less attractive to women than either medium or low voices, which do not differ in attractiveness. The main effects of manipulations of variance of fundamental frequency on vocal attractiveness and benevolence did not reach significance, but there was a significant interaction on the benevolence factor, with high or low average fundamental frequency manipulations being rated particularly low for voices with low variance of fundamental frequency.     

Gender differences in the initiation and attribution of tactile intimacy

Cultural norms may restrict the demonstration of intimacy between men, such that male adults are relatively unlikely (in comparison to females) to display affection in public by hugging or putting hands around one another's waists. Study 1 examined via a role playing technique how the gender composition of a dyad and types of friendship influence tactile greetings. Males displayed less physical intimacy with male friends than with female (platonic or dating) friends and less than females displayed with their same-sex friends. Study 2 examined subjects' perceptions of and attributions about reciprocal touch. Male-male behavior was rated as less normal as a function of the level of physical touch (going from no touch, hugging, to arms around the waist). The normalcy rating of opposite-sex pairs did not vary as a function of the touch manipulation, but female, same-sex pairs' behavior was rated as less normal in the arms around the waist than in either the no touch or hug conditions. In the male same-sex pairs, hugging was seen as more likely to reflect a sexual relationship than no touch, while arms around one another's waist was rated as even more likely to represent a sexual relationship. It was suggested that homophobia, the fear of appearing or being homosexual, may operate to inhibit physical intimacy between men.     

The Role of Perceived Voice and Speech Characteristics in Vocal Emotion Communication

Aiming at a more comprehensive assessment of nonverbal vocal emotion communication, this article presents the development and validation of a new rating instrument for the assessment of perceived voice and speech features. In two studies, using two different sets of emotion portrayals by German and French actors, ratings of perceived voice and speech characteristics (loudness, pitch, intonation, sharpness, articulation, roughness, instability, and speech rate) were obtained from non-expert (untrained) listeners. In addition, standard acoustic parameters were extracted from the voice samples. Overall, highly similar patterns of results were found in both studies. Rater agreement (reliability) reached highly satisfactory levels for most features. Multiple discriminant analysis results reveal that both perceived vocal features and acoustic parameters allow a high degree of differentiation of the actor-portrayed emotions. Positive emotions can be classified with a higher hit rate on the basis of perceived vocal features, confirming suggestions in the literature that it is difficult to find acoustic valence indicators. The results show that the suggested scales (Geneva Voice Perception Scales) can be reliably measured and make a substantial contribution to a more comprehensive assessment of the process of emotion inferences from vocal expression.     

Physical Attractiveness and Electability:

The link between physical attractiveness and electability is explored in this aricle. "Looks" are the sole cue in an experimental voting situation; and subjects "vote" for males they have previously rated attractive but treat attractive female candidates quite differently. Subjects, male and female, are more likely to vote for women they consider less attractive. While the overall pattern does not change significantly according to the type of office sought by the candidates, some variation exists. Attractive women fare better as candidates for Congress than they do when running for state or local offices.     

Young Infants Match Facial and Vocal Emotional Expressions of Other Infants

Research has demonstrated that infants recognize emotional expressions of adults in the first half year of life. We extended this research to a new domain, infant perception of the expressions of other infants. In an intermodal matching procedure, 3.5‐ and 5‐month‐old infants heard a series of infant vocal expressions (positive and negative affect) along with side‐by‐side dynamic videos in which one infant conveyed positive facial affect and another infant conveyed negative facial affect. Results demonstrated that 5‐month‐olds matched the vocal expressions with the affectively congruent facial expressions, whereas 3.5‐month‐olds showed no evidence of matching. These findings indicate that by 5 months of age, infants detect, discriminate, and match the facial and vocal affective displays of other infants. Further, because the facial and vocal expressions were portrayed by different infants and shared no face–voice synchrony, temporal, or intensity patterning, matching was likely based on detection of a more general affective valence common to the face and voice.     

Interviewers' Voices and Refusal Rates in Telephone Surveys

Interviewers' voice characteristics are related to refusal ratesin telephone interviews. Judges reliably rated vocal and personalcharacteristics of telephone interviewers from recordings ofthe first one-half minute of interview introductions. Interviewerswith low refusal rates were judged as having comparatively higherpitched voices, greater ranges of variation in pitch, greaterloudness, faster rates of speaking, and clearer and more distinctpronunciation. They also were judged as more competent and ashaving a more positive approach to the respondent and the interview.     

People Will Know We Are in Love: Evidence of Differences Between Vocal Samples Directed Toward Lovers and Friends

Research has documented the tendency for individuals to change their voices as a function of different emotional and motivational states, but little attention has been devoted to examining voice modulation in romantic relationships. The present research was conducted to determine (1) the way in which individuals alter their voices when speaking to romantic partners versus friends and (2) if independent raters perceive these differences. Independent raters (N = 80) listened to vocal clips obtained from telephone calls directed toward close same-sex friends and romantic partners. For several clips, raters were able to identify conversational partner (romantic versus friend) with greater than chance accuracy, and this accuracy was positively correlated with vocal pitch and perceived romantic interest. In addition, raters who listened to content-filtered clips judged callers less favorably when talking to their romantic partners than their friends. Results are interpreted in light of the “longing” but vulnerable condition of intense romantic love, and integrated into affection exchange theory and communication accommodation theory.
