How chronotype, sleep-wake cycle, subjective time experience influence retrospective, and prospective memory functioning
No full textBackground: The sleep-wake cycle and chronotype are key contributors to memory consolidation. Emerging evidence also highlights their role in shaping the subjective experience of time, which, in turn, can influence cognitive performance, particularly memory. This study investigated how sleep-wake quality, circadian typology, and subjective time perception relate to failures in retrospective and prospective memory. Method: A total of 666 participants (73% female; M = 37.83 years, SD = 14.65) completed the reduced Morningness-Eveningness Questionnaire (rMEQ), Mini-Sleep Questionnaire (MSQ), Prospective and Retrospective Memory Questionnaire (PRMQ), Subjective Time Questionnaire (STQ), and ad hoc questions about sleep habits during weekdays and weekends. Results: Results indicated that evening-types reported later sleep and wake times, more pronounced sleep-wake disturbances, greater memory lapses, and stronger experiences of time expansion/boredom. Correlational analyses showed that both time pressure and time expansion/boredom were negatively associated with PRMQ scores, leading to increased memory errors. The regression models showed that memory performance was generally predicted by wake factor, time pressure and time expansion/boredom. Then, mediation models revealed that eveningness was associated with greater wake problems, which were positively related to altered time perception (i.e., time pressure and time expansion/boredom), which in turn predicted more frequent retrospective and prospective memory failures. Discussion: These findings suggest that circadian typology, wake-related disturbances, and subjective time perception interactively contribute to memory performance, and propose a model linking biological rhythms and temporal experience to memory functioning, suggesting a possible influence of attention and arousal

INTRODUZIONE ALLA PROTEZIONE DEI DATI PERSONALI
No full textIl pieno sviluppo della persona umana, verso il quale muove il nostro ordinamento, presuppone la necessaria tutela della sfera di riservatezza di ciascun individuo.
Tale esigenza accompagna la persona in ogni momento della sua vita ed è pertanto sentita anche in ambito lavorativo, allorquando si accede al luogo di lavoro per adempiere alla prestazione lavorativa. In forza del contratto col quale
viene assunto, il lavoratore si impegna ad eseguire un’obbligazione che consiste nell’adempiere ad una attività psico-fisica a vantaggio del datore di lavoro; ciò implica un coinvolgimento della sua persona, così legittimando l’esigenza
di una specifica tutela delle informazioni ad egli attinenti
Profili giuridici dell’uso della posta elettronica
No full textLo sviluppo delle nuove tecnologie se da un lato ha portato nel contesto lavorativo nuove potenzialità comunicative in grado di rivoluzionare i metodi e l’organizzazione del lavoro, ha messo in luce anche diverse problematiche e criticità. In particolare, l’utilizzo di Internet e della posta elettronica, modificando il modo di comunicare e quindi di gestire in generale l’attività
lavorativa, ha evidenziato la necessità urgente di tutelare la riservatezza degli individui che utilizzano tali sistemi, garantendo un trattamento dei dati personali legittimo, corretto e trasparente. L’impiego di queste nuove tecnologie
per lo svolgimento delle mansioni lavorative espone il lavoratore alrischio costante di essere controllato e tale controllo può non esaurirsi nella semplice verifica dell’effettivo adempimento della prestazione lavorativa, ma arrivare ad interessare campi privati che devono essere tutelati come riservati. I problemi che più spesso vengono riscontrati nell’utilizzo della posta elettronica in ambiente lavorativo riguardano, infatti, la tutela dei dati personali e il legittimo trattamento che di questi viene fatto

Gender composition of pairs influences joint action effect
No full text: Research on joint action has demonstrated that individuals are sensitive to a coactor's attentional relation to jointly attend stimuli. It has also been suggested that some features are necessary to resolve the discrimination problem (i.e., self-own and other-own actions). In the present study, we aimed to test whether the gender composition of interacting pairs modulated the joint action effect. Same- (female-female or male-male) and mixed- (female-male) gender pairs performed a joint version of flanker tasks in Experiment 1 (90 participants, 50% males), while in Experiment 2 (154 participants, 50% males) Navon tasks were performed. In Experiment 1, a higher joint flanker effect in same-gender pairs than in mixed-gender pairs, and this joint effect was similar to the classical flanker effect reported by males and females in a classical procedure of the task (70 participants, 50% males). In Experiment 2, the same-gender pairs reported a joint Navon effect, which was reversed in mixed-gender pairs. In conclusion, our findings support how the gender composition of interacting pairs plays a role in joint attentional tasks
Circadian motor activity of non-dominant hand reaches acrophase later than dominant hand
Full text linkMotor activity during the first half of nocturnal sleep is lateralized to the non-dominant hand. What remains is to determine which account could explain this phenomenon: the more pronounced homeostatic deactivation of the dominant hemisphere or the circadian asymmetry in the hemispheric activation. To better understand the nature of these motor asymmetries, we performed an ecological study assessing the circadian motor activity in 34 evening, 52 intermediate, and 27 morning types. We observed a significant circadian phase delay of the 24-h motor activity pattern of the left hand in comparison to the right hand, regardless of chronotype. Moreover, we replicated higher motor activity in the left hand in comparison to the right hand in late evening that reached statistical significance only in evening and intermediate types. Analysing motor activity around bedtime and wake-up time, we observed a reverse pattern between circadian typologies: evening types showed higher activity in the left hand in comparison to the right hand before bedtime, while morning types showed significantly higher motor activity in the right hand in comparison to the left after wake-up time. Results support the hypothesis of a different circadian phase relationship between the two hemispheres

The Italian Validation of the Zimbardo Time Perspective Inventory and Its Comparison with Three Time Perspective Inventories
Full text linkThe Zimbardo time perspective inventory (ZTPI) is the most well-known and widely used measure of time perspective. However, the assessment of the psychometric properties of the ZTPI reveals several problems, and various short versions have been proposed to overcome these problems. In a large Italian sample (N = 2295; 1326 women; age range 18–74 years), the present study aimed to test a short version of the ZTPI (ZTPI-16) defined by high frequency items (i.e., “good” items), reviewing the items composition of previous alternative short versions of the scale. Beyond the assessment of the factorial structure of this new short ZTPI, we compared the ZTPI-16 to the original ZTPI (ZTPI-56) and another already validated version of the ZTPI in the Italian context, such as Zimbardo’s Stanford time perspective inventory (ZTPI-22), the short version of the ZTPI (ZTPI-30), and the ZTPI-36 proposed analyzing the data from 24 countries. The results confirmed the psychometric problems of the ZTPI-56, whereas the ZTPI-16 reported adequate structural validity and reliability. Moderate-to-strong correlations between same temporal subscales in different ZTPI versions were also found. These data suggest that the review of the “good” items is a new direction in the development of ZTPI versions with good psychometric properties and comparable data among cultures
