Seeing approach motivation in the avoidance behavior of others: implications for an understanding of pluralistic ignorance

Four studies tested the hypothesis that observers tend to interpret others' actions as approach motivated even when they recognize that their own identical choices were motivated by avoidance. Study 1 found that voters in the 2000 U.S. Presidential election who chose a candidate primarily because of their aversion to the alternative thought that others who voted for the same candidate liked him more than they themselves did. In Studies 2, 3, and 4 participants who learned that others made the same choice as themselves between 2 unappealing flavors of soda orjelly beans estimated that the others would pay more than they would for their common choice. The relevance of these findings for an understanding of pluralistic ignorance is discussed.     

Children's prepared and unprepared lies: can adults see through their strategies?

We investigated adults' ability to detect children's prepared and unprepared lies and truths. Furthermore, we examined children's strategies when lying. Thirty children (11–13 years) were interviewed about one self‐experienced and one invented event each. Half had prepared their statements, the other half not. Sixty adult observers assessed the veracity of 10 videotaped statements each. Overall deception detection accuracy (51.5%) was not better than chance. The adults showed higher accuracy for unprepared statements (56.6%), than prepared statements (46.1%). The adults reported to have used more verbal than nonverbal cues to deception, especially the Detail criterion. The most frequent verbal strategy reported by the children was to use real‐life components (e.g. own or others' experiences); the most frequent nonverbal strategy was to stay calm. Arguably, the low accuracy is due to adults' failure to see through the lying children's strategies. Copyright © 2006 John Wiley & Sons, Ltd.     

Detecting Deceit in Pairs of Children1

This study examined adults’ ability to distinguish between truthful and deceptive pairs of children. Adult observers (N = 88) judged the veracity of one of 22 truthful or deceptive pairs of children (12–13 years). The children were interviewed separately about their real or imagined encounters with an unknown man. Analyses showed that the overall accuracy was 62.5%; significantly better than chance level of 50%. Deception detection accuracy was higher when watching both pair members than when watching one child. The analysis of self‐reported cues to deception given by observers showed that the consistency between the children's statements was the most frequent cue. An analysis of the actual consistency of children's statements showed significantly more contradictions in the deceptive statements.     

A second type of magnitude effect: Reinforcer magnitude differentiates delay discounting between substance users and controls

Basic research on delay discounting, examining preference for smaller–sooner or larger–later reinforcers, has demonstrated a variety of findings of considerable generality. One of these, the magnitude effect, is the observation that individuals tend to exhibit greater preference for the immediate with smaller magnitude reinforcers. Delay discounting has also proved to be a useful marker of addiction, as demonstrated by the highly replicated finding of greater discounting rates in substance users compared to controls. However, some research on delay discounting rates in substance users, particularly research examining discounting of small‐magnitude reinforcers, has not found significant differences compared to controls. Here, we hypothesize that the magnitude effect could produce ceiling effects at small magnitudes, thus obscuring differences in delay discounting between groups. We examined differences in discounting between high‐risk substance users and controls over a broad range of magnitudes of monetary amounts ($0.10, $1.00, $10.00, $100.00, and $1000.00) in 116 Amazon Mechanical Turk workers. We found no significant differences in discounting rates between users and controls at the smallest reinforcer magnitudes ($0.10 and $1.00) and further found that differences became more pronounced as magnitudes increased. These results provide an understanding of a second form of the magnitude effect: That is, differences in discounting between populations can become more evident as a function of reinforcer magnitude.     

Simulating social interaction to address deficits of autistic spectrum disorder in children.

Autistic spectrum disorder (ASD) is diagnosed on the basis of impairment in reciprocal social interaction and language, and rigidity of behavior. This brief paper describes the development of an experimental intervention for preschool children newly diagnosed with ASD. The rationale for this intervention is the hypothesis that failure to attend to social cues in very early life, of itself, may bear a large share of responsibility for core social and communicative deficits. The intervention, therefore, uses eye-tracking to monitor and trigger rewards for attention to facial expression and direction of gaze.     

Psychological Reactance and Adolescents' Attitudes Toward Tobacco-Control Measures

The theory of psychological reactance predicts that, to the extent that smoking-control measures are perceived as threatening the individual's freedom to choose among behavioral alternatives, they may be met with resistance. Data were collected from a national representative sample of 2,400 young people (ages 16–20) by telephone interviews. Dispositional reactance was shown to be associated with smoking. Principal components analyses revealed that a distinction should be made between attitudes toward weak and attitudes toward strong smoking-control measures. Attitudes toward strong measures were particularly negative among regular smokers. Among regular smokers, dispositional reactance was found to be significantly associated with attitudes toward strong tobacco-control measures. Processes of psychological reactance deserve attention when designing smoking control programs.     

A symmetric and an asymmetric model for the equal-sensation function in olfaction

Data from various intramodel matching experiments in olfaction were analyzed with regard to a symmetric and an asymmetric model for the equal-sensation function. The asymmetric model was discussed in relation to the symmetric model. In all, 11 equal-sensation functions were investigated, and of these 9 were with different pairs of odorants. The following odorants were investigated: hydrogen sulfide, pyridine, dimethyl disulfide, and five odorants obtained by different combustion procedures of animal manure. It was found that the equal-sensation function can be written in the following asymmetric form: $$\varphi _i = b_{ik} \lambda \cdot \varphi _k ^{b_{ik} } ,\psi _i = \psi _k $$ or symmetric form: $$\varphi _i = C^{I - b_{ik} } \cdot \varphi _k ^{b_{ik} } ,\psi _i = \psi _k ,$$ where ?_i and ?_k are stimuli expressed in multiples of respective absolute thresholds, λ and C are general constants invariant of experimental matching method and matched attribute (perceived unpleasantness or intensity). The constants λ and C were calculated both for group data and individual data. The asymmetric form of the equal-sensation function was interpreted in terms of relativity and the symmetric form in terms of measurement.     

The Rights of Man: Libertarian Concern for Men's,But Not Women's,Reproductive Autonomy

Libertarianism enshrines individual autonomy as its central political principle, but it has been criticized for applying this principle selectively. Reproductive decisions can stress the concept of individual autonomy by placing into conflict the claimed rights of each biological parent to choose. Two studies (N₁ = 296; N₂ = 580) show that among U.S. participants, libertarianism is associated with opposition to women's reproductive autonomy and support for men's. Libertarianism was associated with opposition to abortion rights and support for men's right both to prevent women from having abortions (male veto) and to withdraw financial support for a child when women refuse to terminate the pregnancy (financial abortion). Adjusting for the association between libertarianism and conservatism, only the relationship with opposition to abortion rights was rendered nonsignificant. Mediation analyses suggest that hostile sexism may account for libertarians' selective support for men's and not women's reproductive autonomy.
