Children’s Gender Identity in Lesbian and Heterosexual Two-Parent Families

This study compared gender identity, anticipated future heterosexual romantic involvement, and psychosocial adjustment of children in lesbian and heterosexual families; it was furthermore assessed whether associations between these aspects differed between family types. Data were obtained in the Netherlands from children in 63 lesbian families and 68 heterosexual families. All children were between 8 and 12 years old. Children in lesbian families felt less parental pressure to conform to gender stereotypes, were less likely to experience their own gender as superior and were more likely to be uncertain about future heterosexual romantic involvement. No differences were found on psychosocial adjustment. Gender typicality, gender contentedness and anticipated future heterosexual romantic involvement were significant predictors of psychosocial adjustment in both family types

The Role of Gender Information in Pronoun Resolution: Evidence from Chinese

Although previous studies have consistently demonstrated that gender information is used to resolve pronouns, the mechanisms underlying the use of gender information continue to be controversial. The present study used event-related potentials (ERPs) to investigate whether working memory modulates the effect of gender information on pronoun resolution. The critical pronoun agreed or disagreed with its antecedent in gender. Moreover, the distance between a pronoun and its antecedent was varied to assess the influence of working memory. Compared with the congruent pronouns, the incongruent pronouns elicited an N400 effect in the short distance condition and a P600 effect in the long distance condition. The results suggest that the effect of gender information on pronoun comprehension is modulated by working memory

Auctioning Incentive Contracts: An Experimental Study

In this note, we experimentally examine the relative performance of price-only auctions and multi-attribute auctions. We do so in procurement settings where the buyer can give the winning bidder incentives to exert effort on non-price dimensions after the auction. Both auctions theoretically implement the surplus maximizing mechanism. Our experiment confirms this result. Moreover, we observe that the "pie" is shared the same in both auctions between buyer and suppliers both in theory and in the lab (after accounting for learning effects).Key words: Procurement; Price-only auctions; Multi-attribute auctions; Incentive Contracts; Laboratory Experimen

Task-dependent evaluative processing of moral and emotional content during comprehension: an ERP study

Recently, we showed that when participants passively read about moral transgressions (e.g., adultery) they implicitly engage in the evaluative (good–bad) categorization of incoming information, as indicated by a larger event-related brain potential (ERP) positivity to immoral than moral scenarios (Leuthold, Kunkel, Mackenzie, & Filik, 2015). Behavioral and neuroimaging studies indicated that explicit moral tasks prioritize the semantic-cognitive analysis of incoming information but that implicit tasks, as used in Leuthold et al. (2015), favor their affective processing. Therefore, it is unclear whether an affective categorization process is also involved when participants perform explicit moral judgments. Thus, in two experiments, we used similarly constructed morality and emotion materials for which their moral and emotional content had to be inferred from the context. Target sentences from negative vs. neutral emotional scenarios and from moral vs. immoral scenarios were presented using rapid serial visual presentation. In Experiment 1, participants made moral judgments for moral materials and emotional judgments for emotion materials. Negative compared to neutral emotional scenarios elicited a larger posterior ERP positivity (LPP) about 200 ms after critical word onset, whereas immoral compared to moral scenarios elicited a larger anterior negativity (500-700 ms). In Experiment 2, where the same emotional judgment to both types of materials was required, a larger LPP was triggered for both types of materials. These results accord with the view that morality scenarios trigger a semantic-cognitive analysis when participants explicitly judge the moral content of incoming linguistic information but an affective evaluation when judging their emotional content

The Impact of Scoring Weights on Price and Quality Outcomes: An Application to the Procurement of Welfare-to-Work Contracts

This paper assesses the effects of changes in scoring weights in auctions, using a unique sample of bids from private Welfare-to-Work (WTW) service providers to reintegrate groups of unemployed and disabled workers. These providers received points for their price bids and for three proxies of the ex-ante quality of their services: their reputation, a description of the intended plans ('methodology') to reintegrate workers, and the number of job placements they expected to achieve. We exploit the fact that the scoring weights of these award criteria changed in the time period under consideration, while the classification of worker types remained similar. Our estimation results show that increases in the scoring weights of the quality components (vis-à-vis the price weight) result in higher price bids. We also find that a higher weight for both the reputation component and the methodology component contributes to the job-placement of workers
