The role of perspective in identifying domains of reference

We used the contrastive expectation associated with scalar adjectives to examine whether listeners are sensitive to the distinction between common and privileged information during real-time reference resolution. Our results show that listeners used this distinction to narrow the set of potential referents to objects with contrasts in common ground from the earliest moments. These results extend previous evidence that ground information influences real-time language processing by showing that the distinction between common and privileged information is used without being triggered by unusual circumstances.     

Performing and Declining PGD: Accounts of Jewish Israeli Women Who Carry a <Emphasis Type="Italic">BRCA1/2</Emphasis> Mutation or Partners of Male Mutation Carriers

To describe factors associated with preimplantation genetic diagnosis (PGD) decisions among Jewish Israeli BRCA1/2 carriers or spouses of a male carrier, we contacted all women who initiated PGD consultation for embryonic BRCA1/2 mutation detection at Sheba Medical Center, prior to March 2014. Applying a qualitative approach, we asked women to elaborate on the factors they considered in either opting for PGD or discontinuing the screening procedure. Participants were 18 Jewish Israeli women; 14 were carriers of one of the Ashkenazi founder mutations in BRCA1/2, and four were spouses of male mutation carriers, who underwent at least one cycle of PGD. Prior to seeking PGD, ten of the women had no children. At the time of the interview, all but three had at least one child. Three factors emerged as key motivators for PGD: having witnessed the disease in a close relative (n = 12); prior IVF treatment for infertility (n = 12); and having pre-existing frozen embryos (n = 6). Ten women withdrew from the PGD process due to clinical, logistical, and financial reasons. In conclusion, most women decided to withdraw from PGD instead of continuing until a successful conception was achieved. Those who opted for PGD attributed their discontinuation of further screening to the emotional burden that is greatly intensified by practical difficulties.     

Intuitive probabilistic inference in capuchin monkeys

The ability to reason about probabilities has ecological relevance for many species. Recent research has shown that both preverbal infants and non-human great apes can make predictions about single-item samples randomly drawn from populations by reasoning about proportions. To further explore the evolutionary origins of this ability, we conducted the first investigation of probabilistic inference in a monkey species (capuchins; Sapajus spp.). Across four experiments, capuchins (N = 19) were presented with two populations of food items that differed in their relative distribution of preferred and non-preferred items, such that one population was more likely to yield a preferred item. In each trial, capuchins had to select between hidden single-item samples randomly drawn from each population. In Experiment 1 each population was homogeneous so reasoning about proportions was not required; Experiments 2–3 replicated previous probabilistic reasoning research with infants and apes; and Experiment 4 was a novel condition untested in other species, providing an important extension to previous work. Results revealed that at least some capuchins were able to make probabilistic inferences via reasoning about proportions as opposed to simpler quantity heuristics. Performance was relatively poor in Experiment 4, so the possibility remains that capuchins may use quantity-based heuristics in some situations, though further work is required to confirm this. Interestingly, performance was not at ceiling in Experiment 1, which did not involve reasoning about proportions, but did involve sampling. This suggests that the sampling task posed demands in addition to reasoning about proportions, possibly related to inhibitory control, working memory, and/or knowledge of object permanence.

Relations Between Parents’ Anxiety Symptoms,Marital Quality,and Preschoolers’ Externalizing and Internalizing Behaviors

Our objective was to expand understanding of the associations between fathers’ and mothers’ anxiety symptoms, their perceptions of marital quality, and their children’s maladjustment behaviors. Sixty Israeli families with a child aged 3–5 participated. Mothers and fathers completed self-report questionnaires assessing parents’ anxiety symptoms, marital dissatisfaction, and marital overt conflict, and child internalizing and externalizing behaviors. The actor–partner interdependence mediation model (APIMeM) design with distinguishable dyads within a path analysis framework was used. Findings showed that marital dissatisfaction of both mothers and fathers partially mediated the links between mothers’ anxiety and child behaviors. For externalizing behaviors, actor and partner effects were found, so that mothers’ anxiety symptoms predicted mothers’ own marital dissatisfaction (actor effect) and fathers’ marital dissatisfaction (partner effect), which, in turn were linked with children’s externalizing behaviors. As for internalizing behaviors, only actor effect was found, so that mothers’ anxiety symptoms were linked with maternal dissatisfaction, which, in turn, was linked with child internalizing behaviors. For fathers’ anxiety symptoms, the APIMeM indicated only direct effects on both internalizing and externalizing behaviors. These findings highlight the risk associated with parental anxiety and the contribution of the marital relations to children’s adjustment and are discussed in light of Bronfenbrenner’s ecological model and Emotional Security Theory.     

Sensitivity to Shared Information in Social Learning

Social learning has been shown to be an evolutionarily adaptive strategy, but it can be implemented via many different cognitive mechanisms. The adaptive advantage of social learning depends crucially on the ability of each learner to obtain relevant and accurate information from informants. The source of informants’ knowledge is a particularly important cue for evaluating advice from multiple informants; if the informants share the source of their information or have obtained their information from each other, then their testimony is statistically dependent and may be less reliable than testimony from informants who do not share information. In this study, we use a Bayesian model to determine how rational learners should incorporate the effects of shared information when learning from other people, conducting three experiments that examine whether human learners behave similarly. We find that people are sensitive to a number of different patterns of dependency, supporting the use of a sophisticated strategy for social learning that goes beyond copying the majority, and broadening the situations in which social learning is likely to be an adaptive strategy.     

That Which “Has No Name in Philosophy”: Merleau-Ponty and the Language of Literature

In this paper I address some related aspects of Merleau-Ponty’s unfinished texts, The Visible and the Invisible and The Prose of the World. The point of departure for my reading of these works is the sense of philosophical disillusionment which underlies and motivates them, and which, I argue, leads Merleau-Ponty towards an engagement with art in general and with literature in particular. I suggest that Merleau-Ponty’s emerging conception of ethics—premised on the paradox of a “universal singularity” and concerned with the concrete experience of the individual subject, rather than with abstractions and formal categories—can best be articulated through the formalist concept of “defamiliarization,” the fundamental performativity of all literature, and the dialogic relations which, though inherent in all discourse, become most powerfully evident in the dynamics of reading.
