Sexual Receptivity Signal of Lordosis Posture and Intra-Sexual Competition in Women

Previous research has shown that women may use self-enhancement strategies to compete with one other. Lumbar curvature in women is considered to enhance a woman′s attractiveness, potentially due to its role in bipedal fetal load and sexual receptiveness. The current study investigated the role of lumbar curvature on women’s perceptions of sexual receptiveness as well as its role in women’s intrasexual competitiveness. Study 1 (N = 138) tested and confirmed that women’s intrasexual competition influences their perception of sexual receptivity of women as a function of lordosis posture depicted in a standing posture. Study 2 (N = 69) replicated these results and extended them to other postures, namely, the quadruped and supine positions. Study 3 (N = 106), using a two-alternative forced-choice task, revealed that other women perceive relatively larger arched-back postures as more threatening to their relationship and frequently as being more attractive. Collectively, this work suggests that women consider a lordotic posture in other women as a signal of sexual receptivity and perceive it as a threat to their relationship. This research provides robust support for the sexually receptivity hypothesis of lumbar curvature, questioning the alternative morphological vertebral wedging hypothesis.

Alternating Italian thetic and sentence-focus constructions

In this article we study the alternation between the two most prominent Italian thetic and sentence-focus constructions, viz. the Syntactic Inversion Construction (henceforth: SIC), e.g. Arriva il treno (‘The train is arriving’), and the Presentational Cleft (henceforth: PC), e.g. C’è il treno che arriva (‘The train is arriving’). Based on the existing literature on the two constructions and drawing inspiration from a number of cognitive-functional hypotheses pertaining to constraints on the amount of referentially new constituents that can be conveyed in a single clause, we put forward the hypothesis that Italian language users are more likely to prefer the PC over the SIC if the utterance involves a high number of referentially new constituents. To assess this hypothesis, we constructed a pilot experiment consisting of a 100-split forced choice task that was administered by means of an online questionnaire to 66 native speaker participants. The results of the experiment indicate that the preference for the PC indeed increases if the number of referentially new constituents is higher. This is however not the only factor involved in the alternation and the preference of the language users seems not only to be determined by the number of referentially new constituents, but also by their syntactic status.

Postverbal subjects in child Italian: Argument structure, discourse and the definiteness effect

While previous work on postverbal subjects in Italian has shown that young children are sensitive to the effects of argument structure and definiteness, little is known about the acquisition of postverbal subjects at the VP-periphery. In response, the present study investigated such subjects under new-information focus by monolingual Italian children (6;1 – 7;4). For this, we employed an elicitation task and a forced-choice task. The results indicated that the children use postverbal subjects at the VP-periphery felicitously, although they do not perform at ceiling. Unexpectedly, the results also suggested possible remnant difficulty with the definiteness effect. However, after comparison with adult data we argue that this is not a developmental issue and instead may suggest that our children were aware that the definiteness effect is not about definiteness per se.

Locative Inversion, PP Topicalization, and Weak Crossover in English

The literature on locative inversion in English currently disputes whether locative inversion differs from PP topicalization in permitting a quantifier in the fronted PP to bind a pronoun in the subject. In order to resolve this dispute, this paper runs two experiments on Amazon Mechanical Turk, one an acceptability judgment task and the other a forced-choice task. Both find that PP topicalization does not differ from locative inversion: both permit variable binding. Locative inversion also does not differ from a minimally different sentence with the overt expletive there. These findings remove an argument against the null expletive analysis of English locative inversion, and they also show that weak crossover is not uniformly triggered by A-bar movement.

The Production of Relatives in Mandarin Children With Specific Language Impairment–From the Perspective of Edge Feature Underspecification Hypothesis

This paper is a first attempt to investigate the production of Relative Clauses (RCs) in Mandarin children with Specific Language Impairment (SLI) (aged 4; 5 to 6; 0) and their typically developing (TD) peers. The data from a preference choice task suggested that (i) Children with SLI performed better on the subject-gapped than object-gapped RC; (ii) Children with SLI performed substantially worse than their TD peers on the RCs production; (iii) Children with SLI were more inclined to omitting the complementizer and using simple sentences and sentence fragments as avoidance strategies. The Edge Feature Underspecification Hypothesis may explain not only the asymmetry of production seen in children with SLI, but also the presence of errors and avoidance strategies used by this population in the task.
