Cold pressor stress reduces left cradling preference in nulliparous human females

The left cradling preference refers to the finding that women hold their infants more frequently on the left side of their own bodies. Several observational studies showed reduced left cradling during stressful circumstances, such as mother-infant separation, or domestic violence. However, until now no experimental study was conducted to investigate the immediate impact of stress on cradling behaviour. Half of the 64 female subjects participating were randomly assigned to a stressful bilateral cold pressor test. The remaining subjects performed a non-stressful control procedure. Before and after this intervention, cradling behaviour was assessed using a baby-like doll. Subjects showed a left cradling preference prior to the intervention. The cold pressor test increased blood pressure and heart rate significantly. A repeated ANOVA revealed an interaction of intervention (cold pressor vs. control) X assessment period (pre- vs. post-intervention), indicating that cold pressor stress reduces left cradling behaviour in female volunteers. Our data indicate that stress influences cradling preference. This may be of relevance for caregiver-infant interactions.     

Preadolescents' and adolescents' online communication and their closeness to friends

The 1st goal of this study was to investigate how online communication is related to the closeness of existing friendships. Drawing from a sample of 794 preadolescents and adolescents, the authors found that online communication was positively related to the closeness of friendships. However, this effect held only for respondents who primarily communicated online with existing friends and not for those who mainly talked with strangers. The 2nd goal was to refine 2 opposing hypotheses, the rich-get-richer and the social compensation hypotheses. Consistent with the rich-get-richer hypothesis, socially anxious respondents communicated online less often than did nonsocially anxious respondents. However, socially anxious respondents perceived the Internet as more valuable for intimate self-disclosure than did nonsocially anxious respondents, and this perception in turn led to more online communication. This result is consistent with the social compensation hypothesis. Online communication and closeness to friends increased with age. There was a curvilinear relationship between age and perceived value of the Internet for intimate self-disclosure, such that 15-year-olds were at the epitome of online self-disclosure. Girls were closer to friends and more socially anxious than were boys.     

Procedural fairness, outcome favorability, and judgments of an authority's responsibility

Fairness theory (R. Folger & R. Cropanzano, 1998, 2001) postulates that, particularly in the face of unfavorable outcomes, employees judge an organizational authority to be more responsible for their outcomes when the authority exhibits lower procedural fairness. Three studies lent empirical support to this notion. Furthermore, 2 of the studies showed that attributions of responsibility to the authority mediated the relationship between the authority's procedural fairness and employees' reactions to unfavorable outcomes. The findings (a) provide support for a key assumption of fairness theory, (b) help to account for the pervasive interactive effect of procedural fairness and outcome favorability on employees' attitudes and behaviors, and (c) contribute to an emerging trend in justice research concerned with how people use procedural fairness information to make attributions of responsibility for their outcomes. Practical implications, limitations, and suggestions for future research also are discussed.     

Projective drawings for assessing stress among subjects with medical symptoms compatible with sick building syndrome, and validation of a modified version of the Stress Load Index from the Drawing Personality Profile: a pilot study

It was hypothesized that subjects with medical symptoms would show more signs of stress in projective drawings. A Stress Load Index, including five signs of stress in drawings, was evaluated. A questionnaire with an instruction to draw "a person in the rain" was sent to a cohort of 195 subjects, and the drawings were analysed blindly for eight stress items. Men had a higher index than women (p < .05) and drew clouds more often (p < .05). Drawing of clouds was associated with headache (adjOR = 4.28; 95% CI 1.75; 11.68). Drawing of puddles was associated with ocular symptoms (adjOR = 3.22; 95% CI 1.38, 7.50), facial dermal symptoms (adjOR= 2.94; 95% CI 1.28, 6.81), and tiredness (adjOR = 2.44; 95% CI 1.05, 5.67). Drawing of long rain strokes was associated with nasal symptoms (adjOR = 2.28; 95% CI 1.05, 2.06) and headache (adjOR = 3.20; 95% CI 1.28, 8.05). Age and stress load were predictors of sick building syndrome symptoms (p < .05). In conclusion, a nonverbal projective drawing test detected sex differences which represent directions opposite to those with verbal methods. These need empirical assessment.     

Ingroup vitality and intergroup attitudes in a linguistic minority

In this study we argue that predictions of the impact of group status, status stability and status legitimacy on intergroup attitudes can be refined using the subjective perceptions of various dimensions of ingroup vitality. We tested the main and moderating effects of perceived present, future and the legitimacy of present ingroup vitality and perceived discrimination on intergroup attitudes in a nation-wide probability sample (N= 1,411) of Swedish-speaking Finns, controlling for ingroup identification. We found that those who perceived the legitimacy of present ingroup vitality to be low had more negative intergroup attitudes than those who perceived the legitimacy to be high. Perceived present and future ingroup vitality had no main effects on the dependent variable. Instead, perceived future ingroup vitality moderated the effect of perceived discrimination on intergroup attitudes. In addition, the perceived legitimacy of present ingroup vitality mediated the effect of perceived present ingroup vitality on intergroup attitudes.     

Validation of a Swedish short self-report measure of core affect

This research aimed at validating two self-report composite rating scales of core affect that are useful when quick assessments are required, for instance, of current mood or recalled, anticipated, and experienced emotional reactions. The ratings were derived from the Swedish Core Affect Scales (SCAS) comprising six self-report rating scales of the two orthogonal dimensions of core affect, valence (unpleasantness-pleasantness) and activation (quietness-excitement). In three samples of university students who were requested to rate current moods, affect-inducing sounds, or affect-inducing pictures, the composite ratings were compared to SCAS, two widely used graphical rating scales of valence and activation, and skin conductance responses and the acceleratory peak of heart rate. Three different rating formats were also compared. The results showed that the composite ratings were reliable and yielded the expected correlations with the other ratings and with the physiological affect indicators. No effects of rating format were detected. It is concluded that the composite ratings of valence and activation may be used if quick assessments are called for. Choices can be made of any of three rating formats depending on purpose with the assessments.     

The camera perspective bias: a case study

In this case study, we examined how variations of the camera perspective affect adults' assessment of veracity in a real‐life high‐stake situation; a masked male confessing to a very serious crime. The interview, conducted by one of Sweden's most awarded journalists, lasted 30 minutes and consisted of over 100 detailed questions about the crime. The interview was videotaped simultaneously by three cameras positioned at different locations, each taking a unique visual perspective. One camera focused on the suspect only, one on the interviewer only, and one equally on the suspect and the interviewer. Each videotape was shown to 32 adult observers (N = 96) who were asked to assess the suspect's veracity and to report subjective cues justifying their veracity assessment. The results confirmed the camera perspective bias, by showing that the observers in the ‘suspect only’ condition assessed the confession as significantly more reliable than did the observers in the ‘interviewer only’ condition. The observers reported that they relied heavily on verbal cues when assessing the confession, and particularly regarding confidence and consistency. Copyright © 2008 John Wiley & Sons, Ltd.
