Smoking cues that increase craving are subjectively described by smokers as pleasant rather than unpleasant. However, it remains
controversial whether the motivational nature of these smoking cues is consistent with an appetitive or aversion-relief model
of tobacco craving. In the two studies presented here, the Bioinformational model of emotion proposed by Lang was used to
address this issue. In study I, 40 smokers (10 males) assessed a set of tobacco-related pictures and a subset of standard
pleasant, neutral, and unpleasant pictures in order to examine how craving relates to the three general dimensions of emotion:
valence, arousal, and dominance. Results showed that the tobacco-related images were all assessed as appetitive, and craving
was correlated positively with valence (r = .863, p < .0001) and arousal (r = .923, p < .0001) and negatively with dominance (r = −.504, p < .002). In study II, 24 female abstinent smokers were examined using Lang’s startle modulation paradigm in order to assess
whether tobacco-related pictures, compared to standard pleasant and unpleasant ones, inhibited the startle response, consistent
with an appetitive model of tobacco craving. Contrary to expectations, the startle response during visualization of tobacco-related
pictures was more similar in magnitude to the response to unpleasant than to pleasant images, a finding inconsistent with
an appetitive model of tobacco craving. 相似文献
Contact improvisation (CI) is a form of dance based on motor creativity, improvisation and the physical contact between different improvisers dancing together. This will generate different ways of moving and a varied use of motor creativity depending on the dancers involved. This study aims to observe the differences in movement generation depending on the partner by using OSMOS (Observational System of Motor Skills; Castañer & Camerino 2006; Castañer et al., 2009). Four contact improvisers were video‐recorded while dancing in duets. Data were analysed by three observers using Theme Coder software (Magnusson, 1996) for the detection of T‐patterns and the production of event frequency charts. The results show that (1) the motor skills that appear most frequently are the conduction of partners, elevations, spatial level changes and turns; (2) motor creativity is affected by the partner, as there is a reciprocal influence in the dance; and (3) motor creativity is enhanced by interaction with a partner. 相似文献
There is growing evidence that personality traits are affected by many genes, all of which have very small effects. As an alternative to the largely unsuccessful search for individual polymorphisms associated with personality traits, the authors identified large sets of potentially related single nucleotide polymorphisms (SNPs) and summed them to form molecular personality scales (MPSs) with from 4 to 2,497 SNPs. Scales were derived from two thirds of a large (N = 3,972) sample of individuals from Sardinia who completed the Revised NEO Personality Inventory (P. T. Costa, Jr., & R. R. McCrae, 1992) and were assessed in a genomewide association scan. When MPSs were correlated with the phenotype in the remaining one third of the sample, very small but significant associations were found for 4 of the 5e personality factors when the longest scales were examined. These data suggest that MPSs for Neuroticism, Openness to Experience, Agreeableness, and Conscientiousness (but not Extraversion) contain genetic information that can be refined in future studies, and the procedures described here should be applicable to other quantitative traits. 相似文献
Mainstream media’s promotion of dangerously thin female images likely lowers self-image satisfaction and contributes to pathological body concerns and disordered eating among women. We tested upward and downward social-comparison effects on self-evaluations by exposing 145 Spanish women to images of thin (upward) or overweight (downward) models. We also tested whether explicitly asking or not asking participants to compare themselves with the models would moderate social comparison effects. Exposure to thin models deteriorated body image while increasing body dissatisfaction and anxiety. Conversely, exposure to overweight models improved body image and decreased body dissatisfaction but it did not affect anxiety. Whether participants were asked to compare themselves to the models explicitly or implicitly had no effect on the participants’ responses. Furthermore, pre-existing body image concerns were not associated with the pre-to-post exposure effects. We propose that increasing the representation of normal weight and overweight women in media advertisements could help to neutralize or at least reduce the negative impact of media’s practice to idealize thin and overly thin women as symbols of female beauty.
In the paper we obtain a new characterization of the BCK-algebras which are subdirect product of BCK-chains. We give an axiomatic algebraizable extension of the BCK-calculus, by means of a recursively enumerable set of axioms, such that its equivalent algebraic semantics is definitionally equivalent to the quasivariety of BCK-algebras generated by the BCK-chains. We propose the concept of "linearization of a system" and we give some examples. 相似文献
During the COVID-19 pandemic, institutions encouraged social isolation and non-interaction with other people to prevent contagion. Still, the response to an impending economic crisis must be through the collective organization. In this set of pre-registered studies, we analyse two possible mechanisms of coping with collective economic threats: shared social identity and interdependent self-construction. We conducted three correlational studies during the pandemic in May–October 2020 (Study 1, N = 363; Study 2, N = 250; Study 3, N = 416). Results show that shared identity at two levels of politicization (i.e., working-class and 99% identities) and interdependent self-construal mediated the relationship between collective economic threat, intolerance towards economic inequality and collective actions to reduce it. The results highlight that the collective economic threat can reinforce the sense of community—either through the activation of a politicized collective identity, such as the working class or the 99% or through the activation of an interdependent self—which in turn can trigger greater involvement in the fight against economic inequality.

The current paradigm in mental health practice does not completely protect practitioners from theory-induced blindness. Many clinicians continue to rely on stable theoretical frameworks, which, although helpful, can become a hindrance to integrated relational practice. Overreliance on a particular theory or set of techniques can prevent clinicians from adopting a genuinely relational orientation. This article describes the nature of the contemplative-relational orientation using concepts from Martin Buber’s I and Thou and proposes that clinicians wishing to build competency in integrated relational counseling may benefit from contemplative prayer, meditation, and other mindfulness practices. A clinical vignette is provided and illustrates general features of an integrated relational approach, and empirical evidence is advanced to support the benefits of contemplative practice for mental health practitioners. 相似文献
