Essentialism and Nonnaturalist Normative Supervenience

In this essay I defend a kind of nonnaturalist normative supervenience, grounded in the essences of things. Essentialist theories, in fact, give us the tools to treat the nexus of normative supervenience as a nexus of metaphysical necessity, holding between the normative and the natural. In this context, essentialist grounding provides an explanation of normative supervenience that allows us to keep together both supervenience and nonnaturalism. Moreover, to achieve this significant result, I do not make use of hybrid properties, which are both normative and natural. Rather, I endeavour to show that the notion of hybrid property is based on an erroneous notion of grounding.     

Adolescents at Risk of Delinquency. The Role of Parental Control,Trust, and Disclosure

This study investigates the role of parental control, trust, and disclosure as protective factors on individual and peer-group delinquency in a sample of 1420 Italian high school students aged from 14 to18 (M_age = 15.59, SD_age = 1.17), representative of the adolescent student population in Rimini (57.3% males and 42.7% females). A cluster analysis identified different patterns of parental monitoring, associated with different levels of involvement in individual and group delinquency during adolescence. The results showed parental trust, control, and adolescent disclosure to be inversely associated with violent behaviors. Our results challenge the assumption that greater parental control can reduce preadolescents’ antisocial behavior.     

Psychopathic Personality Traits in Relation to Self-report Delinquency in Adolescence: Should We Mind About Interaction Effects?

The aim of the present study was to investigate if interaction effects among Youth Psychopathic Traits Inventory (YPI) Grandiose-Manipulative (GM), Callous-Unemotional (CU), and Impulsive-Irresponsible (II) may add significant information in predicting self-reports of juvenile delinquent behavior among adolescents. A sample of 558 Italian high school students were administered the YPI and the Self-Reports of Delinquency Scale (SRDS) in order to evaluate interaction effects among YPI GM, CU, and II dimensions. Results showed a significant effect for a three-way interaction among the three YPI dimensions in predicting the SRDS total score, β?=?.19, p?<?.01. In conclusion, the findings seem to underline that a three-factor model of psychopathy may help clinicians and researchers in predicting self-reported delinquency better than the individual factors.     

Subjective organization in the episodic memory of individuals with Parkinson’s disease associated with mild cognitive impairment

Word clustering (i.e., the ability to reproduce the same word pairs in consecutive recall trials of an unrelated word list) has been extensively investigated as a proxy of subjective organization (SO) of memorandum. In healthy subjects and in groups of brain-damaged patients, the rate of SO generally predicts accuracy of word list recall. This study aimed at evaluating SO in the performance of patients with Parkinson’s disease (PD) on a word list recall task in order to investigate the basic mechanisms of episodic memory impairment that are frequently observed in these patients. For this purpose, 56 PD patients, who were stratified according to the presence and quality of mild cognitive impairment (MCI), and a group of healthy controls (HCs) were administered a word list task and an extensive battery of neuropsychological tests. Results showed that recall accuracy on the word list task progressively decreased passing from HC to PD patients without cognitive impairment, to patients with single-domain dysexecutive MCI and to patients with multiple-domain dysexecutive and amnesic MCI. Conversely, only the latter PD group showed a lower SO score than that achieved by the other groups. In the overall PD group, correlational and regression analyses demonstrated that SO scores and a composite score of executive functions were not reciprocally related, but both provided an independent and significant contribution to the prediction of word list recall accuracy. These data are discussed in terms of the contribution of executive functions and hippocampal storage processes to the onset of memory impairment in PD.     

Interference and conflict monitoring in individuals with amnestic mild cognitive impairment: A structural study of the anterior cingulate cortex

Amnestic mild cognitive impairment (aMCI) is a clinical condition characterized by memory impairment in the absence of any other cognitive impairment and is commonly associated with high conversion to Alzheimer's disease. Recent evidence shows that executive functions and selective attention mechanisms could also be impaired in aMCI. In this study, we investigated performance differences (i.e., reaction times [RTs] and accuracy) between a group of aMCI participants and a group of age‐matched healthy individuals on the attentional network task (ANT) focusing on situations with increased interference. In particular, we assessed the relationship between interference and conflict effects and grey matter volumes (GMVs) of the anterior cingulate cortex (ACC)/pre‐supplementary motor area in the entire sample because of its crucial role in conflict monitoring. When compared with controls, aMCI participants were less accurate on the ANT, showing increased interference and conflict effects, but no differences in RTs. In addition, aMCI participants exhibited lower GMV in the ACC than controls. While better accuracy for interference and conflict effects was associated with an increase of GMV in the ACC for both groups, RTs from the interference effect were negatively correlated with GMV of the ACC only in aMCI participants. In other words, lower GMV values of the ACC were paralleled with significantly impaired performance in terms of interference resolution. In conclusion, our study suggests the presence of a selective impairment in interference and conflict monitoring in aMCI, which in turn is associated with decreased GMVs in the ACC.     

Global/local processing and negative priming: the influence of selection difficulty and stimulus exposure

Negative priming is a decrement in performance observed when a previously ignored stimulus is re-presented as a target. The present study examined the relation between selection difficulty and negative priming in five experiments that used hierarchical stimuli (large letters made up by small letters). The results show that negative priming is greater when subjects direct attention to the local level (more difficult selection) than when they direct attention to the global level (less difficult selection). However, that occurs only when exposure of prime and probe is sufficiently long. With shorter presentations, negative priming is still observed but is no longer modulated by selection difficulty. These results suggest that both anticipatory and reactive mechanisms are responsible for the occurrence of negative priming and that instantiation of the reactive mechanism depends on the time available for prime and probe selection.

Personality and Optimal Experience in Adolescence: Implications for Well-Being and Development

Past research has repeatedly identified relations between optimal experience—or flow—and well-being across the lifespan. In the attempt to identify the conditions favoring this experience, some studies took into account personality traits. While most of them operationalized flow in terms of intensity, we presently focused on perceived occurrence versus absence of flow. Specifically, we investigated the relations between flow occurrence, hedonic and eudaimonic well-being, activities associated with flow, and personality in adolescence. A group of 408 Italian teenagers (mean age = 17.31; SD = 1.13) were administered Flow Questionnaire, Satisfaction with Life Scale, Positive and Negative Affect Schedule, Psychological Well-being Scales, and the Big Five Questionnaire. Participants reporting optimal experience in their lives were compared with those not reporting it. Results showed that adolescents experiencing flow reported higher satisfaction with life, hedonic balance, and psychological well-being than their counterparts. Findings from logistic regression analyses further showed that openness to experience was the sole personality factor predicting flow occurrence, and that no personality factors were predictive of type of activities adolescents associated with flow. Findings point to the promotion of optimal experience among adolescents through the support of curiosity and openness to new experiences in engaging opportunities for action. They further call for the development of an integrated model taking into account both individual predispositions and social and cultural factors in well-being promotion.     

The Contribution of Job Happiness and Job Meaning to the Well-Being of Workers from Thriving and Failing Companies

In a time of global economic crisis, workers’ well-being is of paramount concern for both organizations and society at large. Conceptualizations within positive psychology distinguish between hedonic and eudaimonic well-being components, and call for the need to include them in an integrated perspective. Within this framework, the present study aimed at investigating the impact of situational uncertainty on eudaimonic and hedonic well-being, and the spillover effects of work into individuals’ lives. Data were collected from 85 Italian employees at a thriving insurance company and at a failing one. Participants were administered Job Content Questionnaire, Eudaimonic and Hedonic Happiness Investigation, Satisfaction with Life Scale, and Psychological Wellbeing Scales. Data were analyzed through hierarchical regression analyses. Concerning well-being at work, employees at the failing company reported higher job insecurity and lower job happiness compared to employees at the thriving company, while job meaning scores did not differ between groups. Concerning general well-being, an unexpected positive association was found between positive relations and situational uncertainty. A spillover effect of job happiness and meaning on life satisfaction, environmental mastery, and autonomy was also detected. In particular, a moderating effect of job meaning was identified, showing that attributing high importance to one’s job had wide affective consequences, spilling over to global life evaluations. Findings bring forward practical suggestions for well-being promotion, in terms of shifting domain importance (Wu Journal of Happiness Studies 10:37–47, 2009), and investing in multiple life areas (Sirgy and Wu Journal of Happiness Studies 10:183–196, 2009) for the promotion of a balanced life.     

Action matters: The role of action plans and object affordances in selection for action

In a series of three experiments requiring selection of real objects for action, we investigated whether characteristics of the planned action and/or the “affordances” of target and distractor objects affected interference caused by distractors. In all ofthe experiments, the target object was selectedon the basis of colour and was presented alone or with a distractor object. We examined the effect of type of response (button press, grasping, or pointing), object affordances (compatibility with the acting hand, affordances for grasping or pointing), and target/distractor positions (left or right) on distractor interference (reaction time differences between trials with and without distractors). Different patterns of distractor interference were associated with different motor responses. In the button-press conditions of each experiment, distractor interference was largely determined by perceptual salience (e.g., proximity to initial visual fixation). In contrast, in tasks requiring action upon the objects in the array, distractors with handles caused greater interference than those without handles, irrespective of whether the intended action was pointing or grasping. Additionally, handled distractors were relatively more salient when their affordances for grasping were strong (handle direction compatible with the acting hand) than when affordances were weak. These data suggest that attentional highlighting of specific target and distractor features is a function of intended actions.
