Adolescent romantic relationships as a tug of war: The interplay of power imbalance and relationship duration in adolescent dating aggression

The present study investigates the link between power imbalance within the romantic couple and psychological, relational and physical adolescent dating aggression (ADA) perpetration, considering also the role of relationship duration as an indicator of the developmental stage of the relationship. This is the first investigation into whom is perceived to have power in the relationship (the partner or the subject him/herself) by distinguishing between male and female adolescents. Participants were 805 Italian adolescents (36.1% males; 63.9% females) aged 14–20 years (M_age = 17.16 years, SD_age = 1.34), all reporting having been in a romantic relationship currently or within the past 6 months. Males perceiving a balanced relationship reported lower levels of psychological ADA perpetration, and they perpetrated more relational ADA in longer relationships where the partner is perceived to have the power. No significant findings emerged regarding physical ADA. Females perceiving themselves as having the power in the relationship reported higher levels of psychological and physical ADA perpetration. They perpetrated more relational ADA when they perceived the partner as having the power in the relationship. Also, females in longer relationships in which power was not perceived as equally shared between partners reported higher physical ADA perpetration. Finally, for both males and females, longer relationships were characterized by higher levels of ADA toward the partner. Findings highlight the importance of studying the interplay between power imbalance and relationship duration on ADA perpetration, and provide the way to understand possible functions of ADA within a romantic relationship.     

Covert reading of letters in a case of global alexia

This study describes the case of a global alexic patient with a severe reading deficit affecting words, letters and Arabic numbers, following a left posterior lesion. The patient (VA) could not match spoken letters to their graphic form. A preserved ability to recognize shape and canonical orientation of letters indicates intact access to the representation of letters and numbers as visual objects. A relatively preserved ability to match lowercase to uppercase letters suggests partially spared access to abstract letter identities independently of their visual forms. The patient was also unable to match spoken letters and numbers to their visual form, indicating that she could not access the graphemic representations of letters from their phonological representations. This pattern of performance suggests that the link between graphemic and phonological representations is disrupted in this patient. We hypothesize that VA’ residual reading abilities are supported by the right hemisphere.     

Similarity, Cohesion, and Friendship Networks Among Boys and Girls: A One-Year Follow-Up Study Among Italian Children

This study aimed to investigate the follow-up effects of certain characteristics of children??s friendships, such as similarity and cohesion with friends as represented by the children through drawing, as well as the breadth of their friendship networks as perceived by children. Participants were 115 children who were 6 to 9?years old (M?=?7.09.14, SD?=?0.41; 51?% female), attending two primary schools in northwest Italy. We used children??s drawings and self-reported measures to investigate friendship at both dyadic and network levels. Multiple logistic regressions indicated that mean score of similarity was positively associated with friendship network while an increase in cohesion was negatively associated with friendship network at follow-up. These associations did not vary by sex and stability or change of drawn friend. The paper contributes to the knowledge on the subject of friendship among children, especially in light of its focus on the associations between the components of friendship and the friendship network. Findings demonstrated that boys and girls are much more similar than expected.     

Audience design affects acoustic reduction via production facilitation

In this article, we examine the hypothesis that acoustic variation (e.g., reduced vs. prominent forms) results from audience design. Bard et al. (Journal of Memory and Language 42:1-22, 2000) have argued that acoustic prominence is unaffected by the speaker's estimate of addressee knowledge, using paradigms that contrast speaker and addressee knowledge. This question was tested in a novel paradigm, focusing on the effects of addressees' feedback about their understanding of the speaker's intended message. Speakers gave instructions to addressees about where to place objects (e.g., the teapot goes on red). The addressee either anticipated the object, by picking it up before the instruction, or waited for the instruction. For anticipating addressees, speakers began speaking more quickly and pronounced the word the with shorter duration, demonstrating effects of audience design. However, no effects appeared on the head noun (e.g., teapot), as measured by duration, amplitude, and perceived intelligibility. These results are consistent with a mechanism in which evidence about addressee understanding facilitates production processes, as opposed to triggering particular acoustic forms.     

From melody to lexical tone: Musical ability enhances specific aspects of foreign language perception

Previous research shows that music ability provides positive effects on language processing. This study aims at better clarifying the involvement of different linguistic subdomains in this cross-domain link, assessing whether or not musicality and music expertise enhance phonological and lexical tone processing of Mandarin Chinese. In two experiments different groups of adults and children with no previous experience in tonal languages, were invited to perform a same–different task trying to detect phonological and tonal variations in pairs of sequences of monosyllabic Mandarin Chinese words. Main results show that all subjects perform significantly better in detecting phonological variations rather than tonal ones. They also show that both melodic proficiency and music expertise are good predictors for a better tonal, but not phonological identification. Data lead to a model of music-to-language transfer effect in which musicality selectively affects linguistic intonation while leaving phonological processing substantially unaffected.     

A convention or (tacit) agreement betwixt us: on reliance and its normative consequences

The aim of this paper is to clarify what kind of normativity characterizes a convention. First, we argue that conventions have normative consequences because they always involve a form of trust and reliance. We contend that it is by reference to a moral principle impinging on these aspects (i.e. the principle of Reliability) that interpersonal obligations and rights originate from conventional regularities. Second, we argue that the system of mutual expectations presupposed by conventions is a source of agreements. Agreements stemming from conventions are “tacit” in the sense that they are implicated by what agents do (or forbear from doing) and without that any communication between them is necessary. To justify this conclusion, we assume that: (1) there is a salient interpretation, in some contexts, of everyone’s silence as confirmatory of the others’ expectations (an epistemic assumption), and (2) the participating agents share a value of not being motivated by hostile attitudes (a motivational assumption). By clarifying the relation between conventions and agreements, the peculiar normativity of conventions is analyzed.     

Musical training generalises across modalities and reveals efficient and adaptive mechanisms for reproducing temporal intervals

Expert musicians are able to time their actions accurately and consistently during a musical performance. We investigated how musical expertise influences the ability to reproduce auditory intervals and how this generalises across different techniques and sensory modalities. We first compared various reproduction strategies and interval length, to examine the effects in general and to optimise experimental conditions for testing the effect of music, and found that the effects were robust and consistent across different paradigms. Focussing on a ‘ready-set-go’ paradigm subjects reproduced time intervals drawn from distributions varying in total length (176, 352 or 704 ms) or in the number of discrete intervals within the total length (3, 5, 11 or 21 discrete intervals). Overall, Musicians performed more veridical than Non-Musicians, and all subjects reproduced auditory-defined intervals more accurately than visually-defined intervals. However, Non-Musicians, particularly with visual stimuli, consistently exhibited a substantial and systematic regression towards the mean interval. When subjects judged intervals from distributions of longer total length they tended to regress more towards the mean, while the ability to discriminate between discrete intervals within the distribution had little influence on subject error. These results are consistent with a Bayesian model that minimizes reproduction errors by incorporating a central tendency prior weighted by the subject's own temporal precision relative to the current distribution of intervals. Finally a strong correlation was observed between all durations of formal musical training and total reproduction errors in both modalities (accounting for 30% of the variance). Taken together these results demonstrate that formal musical training improves temporal reproduction, and that this improvement transfers from audition to vision. They further demonstrate the flexibility of sensorimotor mechanisms in adapting to different task conditions to minimise temporal estimation errors.     

Media exposure to terrorism and people's risk perception: The role of environmental sensitivity and psychophysiological response to stress

Terrorist attacks have a destabilizing impact on the general population, causing distress and fear. However, not all individuals are equally susceptible to the effects of terror threat. This study aimed to examine whether exposure to terrorism-related pictures interacted with individual differences in environmental sensitivity and psychophysiological response to stress to explain people's risk perception, operationalized as perceived likelihood of a terrorist attack and willingness to trade off one's privacy to increase national security. Ninety-five university students were randomly assigned to one of two conditions (terrorism-related vs. neutral pictures). After watching the pictures, they answered questions concerning risk perception and completed questionnaires. Stress was induced by the Mannheim Multicomponent Stress Test, during which heart rate was recorded. Results showed that the perceived likelihood of future attacks was affected by the interaction between exposure to terrorism pictures and psychophysiological reactivity to stress, whereas willingness to trade off one's privacy to improve national security was influenced by the interaction between exposure to terrorism pictures and environmental sensitivity. The study suggests that individuals high in sensitivity and psychophysiological stress reactivity are particularly affected by terrorism-related pictures. Psychologists should direct their efforts to raise general awareness of the negative effects, especially for some people, of such media coverage.     

Lack of control enhances accurate and inaccurate identification responses to degraded visual objects

Recent studies have shown that lack of control induces illusory pattern perception. In this study, we demonstrate that lacking control also affected identification responses to degraded pictures of visual objects. As compared with control participants, participants in whom lack of control was experimentally induced produced identification responses to visual objects at a significantly higher level of degradation of the stimulus. Lacking control did not influence accuracy of identification, since the effect was present for both correct and incorrect identification responses, and did not encourage pure random guessing. Our results indicate that lacking control makes individuals more prone to achieve visual closure by attempting earlier identifications of perceptually degraded visual objects. Possible mechanisms involved in this effect are discussed.
