Facial and vocal cues of deception and honesty

Facial expressions and vocal cues (filtered speech) of honest and deceptive messages were examined in posed and spontaneous situations. The question of interest was the degree to which nonverbal cues transmit information about deception. Results indicated that (a) for both the facial and vocal channels, posing (as compared to spontaneous behavior) produced a higher level of communication accuracy; (b) facial expressions of deceptive (as compared to honest) messages were rated as less pleasant, while vocal expressions of deception were rated as less honest, less assertive, and less dominant, particularly in the posed condition; (c) the sender's ability to convey honesty was negatively correlated with his/her ability to convey deception, suggesting the existence of a demeanor bias—individual senders tend to appear and sound consistently honest (or dishonest) regardless of whether they deliver an honest or a deceptive message; (d) in the posing condition, the sender's abilities to convey honesty/deception via facial and vocal cues were positively and significantly correlated, whereas in the spontaneous condition they were not; and (e) senders whose full (unfiltered) speech indicated more involvement with their responses were judged as more honest from both their vocal (filtered speech) and facial cues, in both the honest and deceptive conditions.     

An application of the state-trait concept to the need for achievement

This study concerned relationships between state (situationally defined) n Ach, trait n Ach, and sex of subject in 80 college freshmen. Three standard n Ach tests (the Adjective Check List, Personal Preference Schedule, and TAT measures) and the mean of n Ach states measured under nonarousal conditions were used as trait measures. State measures of n Ach were also obtained in four experimental conditions (Social Ability, Success-Failure, Conventional Arousal, and Extrinsic Competition). There were no significant correlations between the four trait measures. The mean of states in the neutral conditions was highly predictive of states in three of the four arousal conditions, but none of the standard trait tests predicted state arousal to any significant extent.     

Less Religion,Better Society? On Religion,Secularity, and Prosperity in Scandinavia

Abstract : Phil Zuckerman argues in his book Society without God that Scandinavian secularity is strongly correlated to Scandinavian prosperity. In this article, we argue that such usage is premature. First, there are methodological issues that are not properly dealt with. Second, providing a causal narrative in addition to mere correlation is needed. Third, we argue that the causes of Scandinavian prosperity are found in close connection to Scandinavian Lutheranism.     

Belief in a just world and trust

Three studies examined the relationship between belief in a just world and level of trust. Results showed that subjects with a high level of belief in a just world were (a) less suspicious with regard to deception in a social-psychological experiment, (b) less suspicious with regard to the promise of a free gift, and (c) less suspicious with regard to the government's position on several public issues. The same studies also examined the relationships among belief in internal-external control, authoritarianism, and level of trust. In some but not all cases, belief in internal control and high level of authoritarianism were related to more trusting attitudes. It was suggested that the relationship between internality (as measured by the I-E Scale) and trust was mediated by the construct of belief in a just world.     

The impact of education and selected traits on sex-role related goals and attitudes

Questionnaires that assessed educational goals, career goals, preferred and expected career commitment, sex-role attitudes, age, college class, height, and weight were completed by 884 male and female undergraduates representing two racial groups and two age groups. Age, size, and college class were unrelated to women's goals and attitudes, whereas men chose more traditional careers as their education progressed. Technical college students tended to be more traditional than university students. Implications for related research are discussed.     

A genetic and environmental analysis of sensation seeking

The genetic and environmental contributions to the trait of sensation seeking were analyzed using the responses of 422 pairs of twins to the Sensation Seeking Scale (Form IV). The biometrical method of Jinks and Fulker was applied to the data. The data fit the model indicating the likelihood of a predominantly additive gene action controlling the general trait. The heritability figure of 58% (69% of the reliable variance) was quite high for a personality trait. Data from other studies suggest that the heritability of the personality trait rests upon specific inherited biological traits, such as the biochemicals of the brain and gonadal hormones which affect arousability of the central nervous system and relevant traits, such as mood, impulsivity, risk taking, and sociability.     

Controlling nonverbal displays: Facial expressions and tone of voice

This study investigated the hypothesis that facial expressions are more controllable and closer to one's awareness than vocal cues. Specifically, it was suggested that nonverbal displays are a function of three factors: (a) expressiveness, or the tendency to display spontaneous nonverbal cues: (b) controllability, or the ability to voluntarily suppress or exaggerate one's spontaneous display: and (c) demeanor, or the sender's tendency to convey a particular impression regardless of his/her experienced emotion. Subjects' facial and vocal reactions to affective stimuli were recorded in a spontaneous condition or under instructions to magnify or conceal reactions to these stimuli. It was shown that information conveyed by facial expressions was best accounted for by controllability whereas information conveyed by tone of voice was best accounted for by expressiveness and demeanor.     

The other way around: Effects of causal attributions on estimates of consensus,distinctiveness, and consistency

It was hypothesized that the attributed cause of a given person's behavior will affect inferences about its generalizability over persons (consensus), stimuli (distinctiveness), and circumstances (consistency). Moreover, these effects were expected to parallel the effects of consensus, distinctiveness, and consistency information on causal attributions. Experiment 1 provided support for these predictions but also showed that attribution affected consensus judgments less than it affected judgments of distinctiveness and consistency, particularly when consensus was not the first characteristic estimated. Using a different set of stimulus materials and a different manipulation of attribution, Experiments 2 and 3 provided further evidence for the effects of attribution on inferences of consensus information. Experiment 3 indicated that the false consensus effect—actors' tendency to assume that the majority of people share their behavior—may be due to actors' tendency to attribute their behavior to situational factors. Implications of the present studies for biased estimates of consensus and the use of consensus and attribution as mediating variables are discussed.     

Determinants of information-seeking behavior

Two studies examined situational determinants of choice among anagram tests that varied both in difficulty and in diagnosticity (the information they provided about one's own ability). In both studies, subjects worked on a preliminary anagram test before making their choices. Study 1 manipulated level of performance on the preliminary test. Results showed that high performance led to preferring more difficult and more diagnostic tests. In Study 2, subjects were either paid or not paid for their performance on the preliminary test. Results showed that pay led to a preference for more diagnostic tests. Unexpectedly, results of both studies showed that although difficulty and diagnosticity were defined independently of one another, they were not perceived as such. Thus, high diagnostic tests were perceived as more difficult; more difficult tests were perceived as more diagnostic; and the difference between high and low diagnostic tests in perceived diagnosticity and choice of items (high diagnostic tests had higher scores on both measures) were more pronounced among more difficult tests. Motivational as well as cognitive interpretations of the results were discussed.
