Preference of dissonance reduction modes as a function of their order,familiarity and reversibility

Two central hypotheses of the original version of the theory of cognitive dissonance (Festinger, 1957) (1) that dissonance is to be conceived of as a primary drive and (2) that in order to reduce dissonance less resistant cognitions will be changed more than highly resistant ones led to hypotheses which were confirmed by two experiments. In Experiment I, a 2 × 3 factorial design, order and familiarity of dissonance reduction modes were manipulated. After receiving a dissonant information the subjects were offered a relatively low and a relatively high resistant cognition for dissonance reduction, each being placed first (series I, high-low resistance) or last (series II, low-high resistance) respectively. Subjects did (known) or did not (unknown) read these modes before reacting to them. Under the unknown condition dissonance will be reduced more with a specific mode if it is placed first than last. With known reduction modes the order of presentation does not have an effect. Under series I condition the first-placed, higher-resistant cognition will be changed more in the unknown condition than in the known condition. Under the series II condition the first-placed, lower-resistant cognition will be changed equally in the known and unknown condition. In short, the higher-resistant cognition will be changed more, only when it is placed first and when the following modes are not known. Two explanations for these results are possible: (1) The more dissonance is reduced by changing a more or a less resistant congnition, the less further reduction is necessary; (2) dissonance will be reduced in an internally consistent way. Experiment II excluded the first explanation. Subjects were allowed to revise their original way of reducing dissonance. First, subjects in one condition received series I unknown and subjects in the other condition received series II unknown. Reacting to the dissonance reduction modes the second time, there was more revision when the high-resistant congition was placed first (series 1 revision) than when placed last (series II revision). These results support the hypothesis that dissonance reduction by changing a less-resistant congnition more and changing a high-resistant one less is preferred. Implications of the results of the two experments for the stability of dissonance reduction, the method and interpretation of dissonance experiments are discussed.     

Is there a role of depressive symptoms in the fear-avoidance model? A structural equation approach

The fear-avoidance (FA) model has gained widespread acceptance as a conceptual framework for investigating psychological factors such as FA beliefs and avoidance behavior, which contribute to chronic back pain and reduced functioning. Depressive symptoms are supposed to be related to FA beliefs and to foster avoidance behavior. This study aims to investigate the multivariate assumptions of the FA model with a focus on the role of depressive symptoms. A total of N = 360 patients with chronic nonspecific low back pain at admission of inpatient orthopedic rehabilitation participated in the survey. Measures included a numeric pain rating scale, Fear-Avoidance Beliefs Questionnaire, Pain Anxiety Symptoms Scale, Hannover Functional Ability Questionnaire and Patient Health Questionnaire. Using structural equation modeling (SEM), we construed a basic FA model and subsequently extended it by adding symptoms of depression as a covariate. The results of SEM indicated a good model fit for a basic FA model (χ²(263) = 431.069, p < .001, RMSEA = .042, CFI = .964, WRMR = .986). They confirmed the hypothesized relations and supported single mediations of the relationship between pain and functioning by FA beliefs and avoidance behavior. A second model including symptoms of depression as additional covariate (χ²(511) = 722.761, p < .001, RMSEA = .034, CFI = .956, WRMR = .949) showed a high impact of depressive symptoms on all FA model variables leading to a decrease of the FA mediations. The findings provide empirical support for the multivariate FA model and underline the importance of considering depressive symptoms in a multiple-target approach to understand the mechanisms of chronic pain.     

The locus of temporal preparation effects: Evidence from the psychological refractory period paradigm

In reaction time (RT) tasks, responses are especially fast when participants can anticipate the onset of an imperative response signal. Although this RT facilitation is commonly attributed to temporal preparation, it is unclear whether this preparation shortens the duration of early or late processes. We used the effect propagation property of the psychological refractory period paradigm to localize the effect of temporal preparation. Manipulation of temporal uncertainty affected the RT of Task 1, regardless of the level of stimulus onset asynchrony (SOA). Consistent with the prediction of an early locus of temporal preparation, this effect propagated completely to the RT of Task 2 at short SOAs, but propagation diminished virtually to zero at long SOAs.     

The attentional blink effect: influence of negative words in an affective valence categorization task

In this study, we explored the emotional modulation of the Attentional Blink effect. In a Rapid Serial Visual Presentation procedure, a word (Target 1), either positive, negative or neutral, was followed by the word "WATER" (Target 2) in one half of the trials. The task included two conditions. In one of them, participants only had to detect the word "WATER". In double-response trials, participants also categorized Target 1's valence. Results showed that the detection of Target 2 was impaired in the double-response condition, this impairment being greater when negative word appeared as Target 1, as compared to positive and neutral words. However, these effects were independent on the Anxiety-Trait levels of participants. Overall, the pattern of data suggests that cognitive resources are focused on negative stimuli when their negative valence is emotionally salient enough.     

Cutaneous saltation within and across arms: a new measure of the saltation illusion in somatosensation

A new objective procedure was used to measure the strength of cutaneous saltation, in order to clarify current debates about the nature of this illusion. Three taps were presented successively to three possible forearm locations. Participants attended to the middle location and reported whether a tap was perceived there. When all stimuli were delivered to the same arm and intertap intervals were short, participants were unable to distinguish real and illusory stimuli at the middle location. When both arms were stimulated, location judgments on one arm were shifted toward a tap subsequently delivered to the other arm. These results challenge the view that saltation is a purely attentional phenomenon, but they are inconsistent with the idea that this illusion is produced in the primary somatosensory cortex.     

Timing matters: Length of leave and working mothers' daily reentry regrets

Dealing with developmental tasks in work and family domains is an important challenge for young and middle-aged adults. We investigated a transition that has evolved into a normative task for women, namely, the retransition back to paid work following maternity leave. In a diary study with 149 mothers who had just returned to work, we examined the daily experienced regrets concerning this return. In addition to personal resources (i.e., emotional stability, feeling prepared for the transition) and financial requirements needed to return to work, daily experienced family stress predicted decisional regrets. Moreover, our results suggest that leave length is related to psychological resilience in the face of day-to-day stress experiences: Late returners reported fewer regrets in general and were unaffected by daily family stress. Return-to-work regrets, in turn, were predictive of withdrawal intentions. This underlines the relevancy of the timing of the transition back to work in terms of successful development during this life phase.

Ambassadors of gender equality? How use of pair forms versus masculines as generics impacts perception of the speaker

Although the use of gender fair language is strongly promoted in German‐speaking countries, the impact of its use on the way speakers are perceived by others is still unknown. Results of two experimental studies showed that irrespective of their sex, speakers using pair forms rather than generic masculines were perceived more competent by both men and women. Also, they were seen as less sexist by male and female listeners with positive attitudes towards linguistic equality. Findings with respect to the attribution of warmth were more complex: they were not only impacted by language use, but also dependent on speaker's sex and listener's attitude towards linguistic equality. Results are discussed in the context of language and stereotypes. Copyright © 2012 John Wiley & Sons, Ltd.     

Men’s personality and women’s perception of their dance quality

Recent research shows that women judge men who show variability in their body movements as good dancers. Here we report data on women’s perception of dance quality in 48 men, aged 18-42 years, and relate them to men’s self-reported personality traits. Male participants completed a standardised personality inventory (the NEO-FFI) and then danced to a basic rhythm while their body movements were tracked with optical 3D motion-capture technology. Dance movements were applied to a featureless virtual humanoid character and judged on their dance quality by 53 women, aged 17-57 years, who viewed 15 s of the rendered video clips of each male dancer. Conscientiousness and social agreeableness was correlated positively and significantly with women’s perception of men’s dance quality. Extraversion showed a positive correlation and neuroticism and openness were associated negatively with women’s perception of men’s dance quality, though these correlations failed to reach significance. We suggest that male dance movements may convey aspects of their personality, though possible consequences in terms of female mate preferences and selection remain to be explored.     

Motivational states influence effort-based decision making in rats: The role of dopamine in the nucleus accumbens

Decision-making policies are subject to modulation by changing motivational states. However, so far, little is known about the neurochemical mechanisms that bridge motivational states with decision making. Here we examined whether dopamine (DA) in the nucleus accumbens core (AcbC) modulates the effects of motivational states on effort-based decision making. Using a cost–benefit T-maze task in rats, we examined the effects of AcbC DA depletions on effort-based decision making, in particular on the sensitivity of effort-based decision making to a shift from a hungry to a sated state. The results demonstrated that, relative to sham controls, rats with AcbC DA depletion in a hungry as well as in a sated state had a reduced preference for effortful but large-reward action. This finding provides further support for the notion that AcbC DA regulates how much effort to invest for rewards. Importantly, our results further revealed that effort-based decision making in lesioned rats, as in sham controls, was still sensitive to a shift from a hungry to a sated state; that is, their preferences for effortful large-reward actions became lower after a shift from a restricted to a free-feeding regimen. These finding indicate that AcbC DA is not necessarily involved in mediating the effects of a shift in motivational state on decision-making policies.
