Summary The aim of this work is the demonstration of a tactile-kinesthetic aftereffect. A sequence of stimuli was offered to adult subjects whose task was to compare two weights presented simultaneously to both hands by means of a Piéron gravimeter. In Experiment 1 the inspection stimuli consisted of two successive presentations of unequal weights for a period of 2 × 10 s. The test stimuli consisted of two equal weights rapidly following an inspection stimulus. Control stimuli consisting of two equal weights not preceded by an inspection stimulus were interspersed in the sequence. The results obtained confirm the existence of a contrast effect after presentation of an inspection stimulus. In Experiment 2 the inspection stimuli consisted of a single presentation of two unequal weights for a period of 20 s. The results confirm those of the first experiment and provide data enabling the contrast effect obtained to be interpreted as a Köhler-type aftereffect. In order to avoid confusion with the kinesthetic-figural aftereffect, we propose to call the effect demonstrated here the Gravimetric Aftereffect. 相似文献
Various studies have found that reading books about positive interactions between ingroup and outgroup characters, known as media vicarious contact, can reduce prejudice. Focusing on the fantasy saga of The Hunger Games, we examined the effects of negative vicarious contact on collective action across two studies. Specifically, we tested whether reading about fantasy characters living in a postapocalyptic conflictual society with large social disparities between advantaged and disadvantaged groups leads advantaged group members to display greater willingness to engage in collective action on behalf of the disadvantaged group. Results from Study 1 (correlational survey in the United Kingdom and United States) and Study 2 (experimental intervention in Italy) revealed that reading The Hunger Games is indirectly associated with greater collective action intentions via increased anger toward injustice. In both studies social dominance orientation (SDO) acted as a moderator, but in opposite directions: mediation was significant for low-SDOs in Study 1, and for high-SDOs in Study 2. Results are discussed in relation to the importance of media vicarious contact via book reading for social change, and to the need to identify the contextual conditions allowing to anticipate the specific moderation pattern that is more likely to emerge. 相似文献
This study explored the influence of each family member’s life satisfaction on the other family members’ life satisfaction in mother-father-adolescent triads. We also explored the influence of each family member’s satisfaction with food-related life and family life on their own life satisfaction (LS) as well as on the other family members’ LS in mother-father-adolescent triads. The influence of family eating habits, food-related parenting practices used by each parent and sociodemographic characteristics on each family member’s LS were also explored. A survey was applied to a sample of 300 two-parent families with one child between 10 and 17 years of age in Temuco, Chile. The questionnaire included the Satisfaction with Life Scale, Satisfaction with Food-related Life scale, Satisfaction with Family Life scale, Adapted Healthy Eating Index, Family Food Behavior Survey and Family Eating Habits Questionnaire. Frequency and sources of family meals as well as sociodemographic characteristics were also consulted. Three multivariate ordinal logit models were proposed, with the dependent variable LS in the three subsamples: mothers, fathers and adolescents. The three logit models were significant, but differed in the explanatory variables. Mothers’ LS was influenced by their children’s LS and vice versa. Mothers’ LS was positively influenced by both their own satisfaction with family life and the fathers’ satisfaction with family life and vice versa. Children’s LS was also positively influenced by their own satisfaction with food-related and family life. Both parents’ LS was influenced by eating habits, food-related parenting practices and sociodemographic characteristics, but in different ways. Therefore, different interventions should be implemented to improve each family member’s life satisfaction.
