Eye gaze cannot be ignored (but neither can arrows)

Recent studies have tried to shed light on the automaticity of attentional shifts triggered by gaze and arrows with mixed results. In the present research, we aimed at testing a strong definition of resistance to suppression for orienting of attention elicited by these two cues. In five experiments, participants were informed with 100% certainty about the future location of a target they had to react to by presentation of either a direction word at the beginning of each trial or instructions at the beginning of each block. Gaze and arrows were presented before the target as uninformative distractors irrelevant for the task. The results showed similar patterns for gaze and arrows-namely, an interference effect when the distractors were incongruent with the upcoming target location. This suggests that the orienting of attention mediated by gaze and arrows can be considered as strongly automatic.     

Role of the dorsal hippocampus in object memory load

The dorsal hippocampus is crucial for mammalian spatial memory, but its exact role in item memory is still hotly debated. Recent evidence in humans suggested that the hippocampus might be selectively involved in item short-term memory to deal with an increasing memory load. In this study, we sought to test this hypothesis. To this aim we developed a novel behavioral procedure to study object memory load in mice by progressively increasing the stimulus set size in the spontaneous object recognition task. Using this procedure, we demonstrated that naive mice have a memory span, which is the number of elements they can remember for a short-time interval, of about six objects. Then, we showed that excitotoxic selective lesions of the dorsal hippocampus did not impair novel object discrimination in the condition of low memory load. In contrast, the same lesion impaired novel object discrimination in the high memory load condition, and reduced the object memory span to four objects. These results have important heuristic and clinical implications because they open new perspective toward the understanding of the role of the hippocampus in item memory and in memory span deficits occurring in human pathologies, such as Alzheimer's disease and schizophrenia.     

The larger the cause,the larger the effect: evidence of speed judgment biases in causal scenarios

ABSTRACT

When two motions appear to be causally related, the spatiotemporal features of motions are sometimes distorted in order to increase the consistency with causal impressions. Here, in four experiments, we tested if varying the speed of an object A could affect the judged speed of an object B that appeared to be causally related to A. Participants were presented with classic launching stimuli (Experiment 1), a variant of launching stimuli in which A could move with uniformly accelerated or decelerated motion (Experiment 2), non-launching stimuli that elicited a causal impression (Experiment 3), and stimuli showing a three-object launching event (Experiment 4). Main results showed that the judged speed of B was systematically biased towards the speed of A, and moreover that the judged speed of B depended on the average speed of A, rather than on the speed of A at the moment of collision as it would be predicted by Newtonian mechanics. The results are consistent with the hypothesis that internal representations of causal events based on property transmission (for instance, impetus) can affect judgments of the low-level properties of causal scenarios.     

The veil and its materiality: Muslim women’s digital narratives about the burkini ban

ABSTRACT

In the summer of 2016, around 30 French cities banned the burkini—swimwear used by Muslim women that covers the entire body and head—from public beaches. French authorities supported the ban by claiming that the burkini was unhygienic, a uniform of Islamic extremism, and a symbol of women’s oppression. Muslim head-coverings, including the burkini, are religious objects whose materiality points to complex semantic meanings often mediated in Internet discourses. Through a qualitative analysis of visual and textual narratives against the burkini ban circulated by Muslim women, this article looks at the way digital media practices help counteract stereotypes and gain control of visual representations. Muslim women focus on two main topics: 1) they challenge the idea of Muslims being ‘aggressors’ by describing the burkini as a comfortable swimsuit not connected with terrorism; 2) they refuse to be considered ‘victims’ by showing that the burkini holds different meanings that do not necessarily entail women’s submission. Muslim women’s digital narratives positively associate the materiality of the burkini with safety and freedom and focus on secular values rather than religious meanings.     

Political opportunity structures and the activism of first- and second-generation Muslims in two Italian cities

ABSTRACT

The present contribution describes Muslims’ opportunities for activism and political participation, as shaped institutionally and discursively, in Milan and Turin. It analyses the interplay between the national level and the local level, and assesses the implications that contrasting local arrangements have for Muslims’ activism, claims-making and, to a certain extent, even self-identifications – especially with reference to young, second-generation Muslims. In Milan Muslims are confronted with a very closed system of political opportunities, while in Turin there appears to be a much more open system, which aims at co-opting second-generation organisations in particular. The consequence is that while in Milan Muslims – especially second-generation ones – are resigned to being merely the recipients of integration policies, in Turin they can conceive themselves more as partners of the city’s institutions, by resorting to a strategy of ‘active citizenship’.     

The Effect of Symbolic Distancing on Delay Tolerance across the Preschool Period

ABSTRACT

We aimed to longitudinally examine how symbolic distancing affects preschool children’s delay tolerance in a delay choice task. We presented children with choices between a smaller immediate reward and a larger delayed reward in conditions with either symbolic stimuli or edible rewards. Overall, symbolic distancing modulated children’s delay tolerance. In particular, whereas in the first phase (T1: 3- and 4-year-olds) children presented with edible rewards chose the larger option more often than children presented with symbolic stimuli, in the second phase (T2: 5- and 6-year-olds), there was no significant difference between children presented with symbolic stimuli and those presented with edible rewards. These results are discussed by examining how children’s delay tolerance changes during the development and comparing children to adult humans in a similar task.
