Developmental trajectory of number acuity reveals a severe impairment in developmental dyscalculia

Developmental dyscalculia is a learning disability that affects the acquisition of knowledge about numbers and arithmetic. It is widely assumed that numeracy is rooted on the “number sense”, a core ability to grasp numerical quantities that humans share with other animals and deploy spontaneously at birth. To probe the links between number sense and dyscalculia, we used a psychophysical test to measure the Weber fraction for the numerosity of sets of dots, hereafter called number acuity. We show that number acuity improves with age in typically developing children. In dyscalculics, numerical acuity is severely impaired, with 10-year-old dyscalculics scoring at the level of 5-year-old normally developing children. Moreover, the severity of the number acuity impairment predicts the defective performance on tasks involving the manipulation of symbolic numbers. These results establish for the first time a clear association between dyscalculia and impaired “number sense”, and they may open up new horizons for the early diagnosis and rehabilitation of mathematical learning deficits.     

Career Adapt-Abilities Scale-Italian Form: Psychometric proprieties with Italian preadolescents

During preadolescence children start to give attention to the future, to formulate thoughts, and to wonder about what they want. They also acquire knowledge and experiment with strategies to assist them in designing their future career. Among the constructs that can now play a relevant role in life designing, the four resources of career adaptability have a prominent role. This article reports the psychometric properties of the Italian version of the Career Adapt-Abilities Scale-International Form 2.0 for a group of middle school students. Two different studies involving Italian preadolescents were conducted. The first study tests the instrument's multidimensional structure, internal consistency and discriminant validity. The second one verifies the factorial structure's across-gender invariance and the test–retest reliability. Results provide strong psychometric support for the CAAS-Italian Form with preadolescents as a valid measure for analyzing their career adaptability and for using it in career counseling and education.     

Rape stereotypes and labeling: awareness of victimization and trauma

For years, studies in the U.S. college population have described the phenomena of date and acquaintance rape. These phenomena have perpetuated myths regarding rape leading to the faulty labeling of the experience by the survivors themselves. Compared with the U.S., in Europe there are very few studies concerning this issue. This preliminary study in Italy comprised surveys of 210 participants who were asked to express their opinions on 2 scenarios of sexual assault (a forced rape and an acquaintance rape). Only 48% of the participants thought that acquaintance rape should be tried in a criminal court.     

Representation of numerical and non-numerical order in children

The representation of numerical and non-numerical ordered sequences was investigated in children from preschool to grade 3. The child's conception of how sequence items map onto a spatial scale was tested using the Number-to-Position task (Siegler & Opfer, 2003) and new variants of the task designed to probe the representation of the alphabet (i.e., letter sequence) and the calendar year (i.e., month sequence). The representation of non-numerical order showed the same developmental pattern previously observed for numerical representation, with a logarithmic mapping in the youngest children and a shift to linear mapping in older children. Although the individual ability to position non-numerical items was related to the child's knowledge of the sequence, a significant amount of unique variance was explained by her type of number-line representation. These results suggest that the child's conception of numerical order is generalized to non-numerical sequences and that the concept of linearity is acquired in the numerical domain first and progressively extended to all ordinal sequences.     

Self-Construal and Psychological Wellbeing in Scottish and Italian Young Adults

The present study investigated the role of self-construal in explaining psychological wellbeing in two European countries. Eight hundred and fifteen Italian and Scottish students completed measures of life-satisfaction, optimism, subjective happiness and a scale measuring interdependent and/or independent self-construal. We obtained three main findings. First of all, scores on the scales of psychological wellbeing were positively associated with scores on the independent scale and independence was found to be the factor that best explained variance in psychological wellbeing. Second, and contrary to our prediction, the Italian group had significantly higher scores for the independence scale than Scots. Third, gender was found to have a significant effect with regard to interdependence of self, life satisfaction, and optimism.     

The role of affordances in inhibition of return

Inhibition of return (IOR) is a response delay that occurs when the target is preceded by an irrelevant stimulus (cue) at the same location. IOR can be object based, as well as location based. The aim of the present study was to investigate the role of the pragmatic features of a visually presented object in causing IOR. Two experiments were carried out using different objects as stimuli, for which the graspable part (affordance) was clearly defined. The presentation of a whole object, with the part commonly used to grasp it located below, served as a cue. The presentation of either the graspable or the ungraspable part of the cued or uncued object served as the target Results showed that responses were slower when the graspable part was shown in the cued location than when the ungraspable part was shown in the same location. The effect was apparently linked to the kind of action necessary to grasp an object.     

Straight to heaven: Rectitude as spatial representation of morality

Abundant literature in cognitive sciences has shown that morality is grounded in bodily experience. Four studies tested the perceptual association between the spatial dimension of straightness and the abstract concept of morality. Study 1 (n = 61) employed an IAT and revealed an association between straight figures and moral related words. Study 2 (n = 83) employed a similar paradigm and further revealed that the effect we found in Study 1 cannot be attributable to the general association between straight figures and positivity. Study 3 (n = 64) revealed that participants showed a stronger preference for straight figures after recalling moral (vs. immoral) deeds. Study 4 (n = 183) showed the specific role of morality, in this sense, as recalling sociable (vs. unsociable) deeds had no significant influence on figure preferences. A small‐scale meta‐analysis confirmed the robustness of our findings. Results are discussed in light of the embodiment theory.     

Adult Attachment,Differentiation of Self,and Relationship Satisfaction in Lesbians and Gay Men

We examined adult attachment styles, differentiation of self, and relationship satisfaction in a sample of 298 Italian lesbians (48%) and gay men (52%), all of whom were ages 19–71 years (M?=?36.1; SD?=?11.8) and in a couple relationship for at least six months. Participants were recruited via the Internet and completed a web-based survey. We tested the hypotheses that attachment insecurity and differentiation of self would predict relationship satisfaction, as well as that differentiation of self would mediate the relationship between adult attachment and relationship satisfaction. Results supported the hypotheses, thus indicating that attachment insecurity and differentiation of self were correlated with and predicted relationship satisfaction. Furthermore, results supported the hypothesized mediating role of differentiation of self. Finally, results indicated that younger participants, lesbians, and participants in civil unions reported higher levels of relationship satisfaction. Implications for counselors and therapists working with LG populations are discussed.
