Regularity and/or consistency in the production of the past participle?

In the present study we have investigated the acquisition of the past participle of Italian verbs of the second (including mostly irregular verbs) and third (including mostly regular verbs) conjugations in school age children, and with simulations with an artificial neural network. We aimed to verify the extent to which children are sensitive to regularity, as opposed to the consistency in the mapping from the infinitive to the past participle. In particular, we predicted that children would learn at some point that verbs of the second conjugation tend to be irregular, and therefore they would be more likely to produce irregularizations for verbs of this class, compared to the verbs of the third conjugation. However, they should also show sensitivity to the phonological mapping consistency within each subclass, learning to produce correct forms on the basis of phonological similarity. In contrast, children should be more likely to produce regular forms for verbs of the third conjugation. Thus, a larger regularity effect would be expected for verbs of the third than of the second conjugation, leading to the prediction of a regularity by conjugation interaction.     

Impossible shadows and lightness constancy

The intersection between an illumination and a reflectance edge is characterised by the 'ratio-invariant' property, that is the luminance ratio of the regions under different illumination remains the same. In a CRT experiment, we shaped two areas, one surrounding the other, and simulated an illumination edge dividing them in two frames of illumination. The portion of the illumination edge standing on the surrounding area (labelled contextual background) was the contextual edge, while the portion standing on the enclosed area (labelled mediating background) was the mediating edge. On the mediating background, there were two patches, one per illumination frame. Observers were asked to adjust the luminance of the patch in bright illumination to equate the lightness of the other. We compared conditions in which the luminance ratio at the contextual edge could be (i) equal (possible shadow), or (ii) larger (impossible shadow) than that at the mediating edge. In addition, we manipulated the reflectance of the backgrounds. It could be higher for the contextual than for the mediating background; or, vice versa, lower for the contextual than for the mediating background. Results reveal that lightness constancy significantly increases when: (i) the luminance ratio at the contextual edge is larger than that at the mediating edge creating an impossible shadow, and (ii) the reflectance of the contextual background is lower than that of the mediating one. We interpret our results according to the albedo hypothesis, and suggest that the scission process is facilitated when the luminance ratio at the contextual edge is larger than that at the mediating edge and/or the reflectance of the including area is lower than that of the included one. This occurs even if the ratio-invariant property is violated.     

Competition in lexical processing of Italian noun/verb homographs

The study investigates the lexical representation of Italian noun/verb homographs, introducing a factor which has been analysed in production studies: the specific-word frequency (SWF). The SWF parameter allows to understand whether the grammatical class information is specified within the lexical knowledge or it is selected during post-lexical stages. We ran six lexical decision tasks employing the priming paradigm and a grammatical decision task to investigate the lexical representation of noun/verb homographs. In addition, we sought to determine the role played by the frequency of representations and the temporal activation of the grammatical class information. Our findings support the claim that these forms have independent representations for each syntactic role they can play. We interpreted these findings in the light of what we call the “Nominal Dominance” effect, which affects the lexical access of noun/verb homographs. We also discuss the relation between nominal dominance and lexical frequency.     

Teaching and Cultural Otherness

This work focuses on the relational dimension of the encounter between teacher and students meant as a structural element for teaching practice. By using theoretical group-analytical and anthropo-analytical coordinates, the authors psychodynamically problematize some relational conditions that may influence learning. This research concentrates on the circumstances that limit and allow the birth of a group arrangement capable to learn from experience, rather than on a perspective to teach-learn in a perfect agreement with planning. Intercultural education is pointed out and located as a horizon and ideal term to guide educational practice.     

Validity and Reliability of the Interpersonal Competence Questionnaire: Empirical Evidence from an Italian Study

Interpersonal competence is crucial to human life, and poor social functioning is a typical feature of various psychopathological conditions. Given the relevance of the construct, increasing attention has recently been paid to the Interpersonal Competence Questionnaire (ICQ; Buhrmester et al. 1988), a 40-item self-report measuring five domains of interpersonal competence. To provide additional data on the cross-cultural adaptability of the ICQ, we developed an Italian version and investigated its psychometric properties with two independent student samples. Respondents were mostly women (about three quarters), ranging in age from 18 to 57. Study 1 (n?=?408) tested factor structure, internal consistency, and convergent validity. Study 2 (n?=?59) investigated test-retest reliability. Taken together, the results of both these studies provided support for the cross-cultural applicability of the ICQ, and revealed interesting associations between interpersonal competence and constructs such as well-being, emotion dysregulation and empathy.     

Influences of Fertility Status on Risky Driving Behaviour

The effects of hormones on human behaviour have been extensively studied, but little attention has been paid to the influence of ovarian hormones on risky driving. Twenty‐five normally cycling women took part in three sessions, including an ovulatory phase estimation session and two experimental sessions: high vs low fertile phases. These two phases were monitored through a urine‐based luteinizing hormone predictor test. In the two experimental sessions, participants were administered the Driving Behaviour Questionnaire and the Vienna Risk‐Taking Test. Results showed that women are more risk‐averse in their driving behaviour during their high‐fertile phase. The influence of hormonal fluctuations on self‐perception of risk attitude when driving was non‐significant. Findings are discussed from an evolutionary perspective.

History and Intentions in the Experience of Artworks

The role of personal background knowledge—in particular knowledge about the context of production of an artwork—has been only marginally taken into account in cognitive approaches to art. Addressing this issue is crucial to enhancing these approaches’ explanatory power and framing their collaboration with the humanities (Bullot and Reber 2012). This paper sketches a model of the experience of artworks based on the mechanisms of intention attribution, and shows how this model makes it possible to address the issue of personal background knowledge empirically. I claim that the role of intention attribution in art experience has been incorrectly accounted in the literature because of an overly narrow definition of “intention.” I suggest that the observer can recover not only the artist’s abstract projects, but any kind of mental states that have played a causal role during the production of the work. In addition, I suggest that this recovery occurs in large part unconsciously and/or implicitly. I provide support for these claims by distinguishing three families of psychological mechanisms of intention attribution that are activated by artworks: one involved in the cognition of artifacts, one devoted to communication, and one involved in action perception.     

A kinematic analysis of age-related changes in grasping to use and grasping to move common objects

Grasping is a complex action which requires high-level motor control. Although the impact of aging on grasping has been investigated in some studies, to date little is known as to how the aging process interacts with the purpose of the movement. The aims of the present study were (i) to investigate the effect of aging on grasping movements, and to explore on how this effect is modulated by (ii) the goal of the task, and by (iii) the characteristics of the target such as its location in the visual field, its orientation and its size. Young and elderly adults were asked to grasp to move or to grasp to use objects of different sizes and orientations, presented either in the central or the peripheral visual field. Movement duration did not differ between the two groups. However, elderly participants required a longer approach phase and showed a different grasping strategy, characterized by larger grip aperture and smaller percentage of wrist rotation in comparison to young adults. Elderly adults showed a decrease in accuracy when grasping objects presented in the peripheral, but not in the central visual field. A similar modulation of the kinematic parameters consisting in longer planning and execution phases in the grasp to use in comparison to the grasp to move condition was observed in both groups, suggesting that the effect of aging might be minimized and compensated in more goal-directed tasks.
