Macrophage activation for tumor cytotoxicity: regulatory mechanisms for induction and control of cytotoxic activity.
Differenze individuali nel ricordo autobiografico relativo al periodo dell'amnesia infantile
Examined individual differences in recollection of autobiographical events of the childhood amnesia period. Two studies were conducted: in the 1st study 3 groups of subjects (8, 12, and 18 yrs old) were tested on events recollection about different childhood periods (0-3; 3-6; 6-8 yrs), The 2nd study investigated individual differences about autobiographical recollection in children with social adaptation problems ("toughs"). Study 1 confirmed the literature data about childhood amnesia. The results obtained from the 2nd study showed that children labelled as "toughs" recollect more events from their past than the others and these events were mainly labeled with negative emotion. The results are discussed within the models supporting the idea that lifestyle and social adaptation could affect the ontogenetic development of episodic autobiographical memor
Giovani, lavoro e welfare in Italia: hard times?
il contributo si propone di fornire alcuni dati giudicati utili per ricostruire la situazione in cui si trovano a vivere i giovani di oggi in relazione ad aspetti tangibili, quali l'ingresso nel mondo del lavoro, il rendimento dei titoli di studio, l'indipendenza dalla famiglia di origine e il sostegno sociale disponibile, senza negare attenzione alla rappresentazione di sè condivisa dai giovani di oggi. In secondo luogo, intende mettere a fuoco con un approfondimento specifico uno degli "adattamenti" possibili ad una situazione non propriamente amichevole: l'emigrazione
Time course of sleep inertia dissipation in memory tasks
Sleep inertia (SI) refers to a complex psychophysiological phenomenon, observed after awakening, that can be described as the gradual recovery of waking-like status. The time course of cognitive performance dissipation in an everyday life condition is still unclear, especially in terms of the sleep stage at awakening (REM or NREM-stage 2) and the relative effects on perfor-mance. The present study aimed to investigate the SI dissipation in different memory performances upon spontaneous morning awakening after uninterrupted nighttime sleep. Eighteen young adults (7 females; mean age 24.9 ± 3.14 years) spent seven non-consecutive nights (one baseline, three REM awakenings and three St2 awakenings) in the laboratory under standard polysomnographic (PSG) control. Participants were tested after three REM awakenings and three St2 awakenings, and three times at 11:00 a.m. as a control condition. In each testing session, participants filled in the Global Vigor and Affect Scale and carried out one memory task (episodic, semantic, or procedural task). For each condition, participants were tested every 10 min within a time window of 80 min. In ac-cordance with previous studies, SI affected subjective alertness throughout the entire time window assessed. Moreover, SI significantly affected performance speed but not accuracy in the semantic task. With reference to this task, the SI effect dissipated within 30 min of awakening from REM, and within 20 min of awakening from St2. No significant SI effect was observed on episodic or procedural memory tasks
The effects of ongoing activity in time estimation in prospective remembering
Two experiments examined whether time-based prospective memory performance is influenced by
the continuous or discontinuous nature of an ongoing activity. The first experiment demonstrated that
prospective memory performance was not influenced by the engagement in continuous or discontinuous
ongoing activity. The second experiment demonstrated that a discontinuous ongoing activity
negatively affected prospective memory performance when participants had to execute two timebased
tasks for which the retention intervals partially overlapped. The results suggest that when
individuals are engaged in multiple time-based tasks, a general timing disruption occurs, with a
proactive interference effect resulting in costs that are detrimental to prospective timing
