In un certo senso, viene data per scontata la sua utilità all'interno del processo formativo. Non sono presenti contributi che indichino “quando” il tutor è utile e “quanto” sia grande questo contributo.

Theoretical models by Baddeley (2001) and by Thorndyke and Hayes-Roth (1982) were used as frameworks for studying respectively Working Memory and Spatial Knowledge. In the introduction, the two models are discussed (chapter 2 and 3 for Working Memory; chapter 4, 5, 6, 7 for the spatial knowledge). Then, possible links between the two issues are highlighted (chapter 8).

The study reported in this paper was aimed at investigating the existence of schemata specifically involved in the cognitive organization of a web page. Particularly, the hypothesis was that the location of some web objects (namely, links to specific contents) might be expected by the users at specific spatial locations. Results confirm that user's expectations are due to the activity of “low” and “high” level schemata allowing performance optimization.

An analysis of shared last names among academics was recently proposed to measure the diffusion of nepotism, the results of which have had a huge resonance. This method was thus proposed to orient the decisions of policy makers concerning cuts and funding. Because of the social relevance of this issue, the validity of this method must be assessed. Thus, we compared results from an analysis of Italian and United Kingdom academic last names, and of Italian last and given names.

In the current research, we detected three sub-populations of C57BL/6J mice that spontaneously responded with avoiding, balancing or approaching behaviours in the presence of the same conflicting stimuli.

In uncovering the psychological challenges that individuals and teams can face, we need research options that integrate psychosocial aspects with behavioral, performance, technical and environmental issues. Future perspectives in Space Psychology and Human Spaceflight are reviewed in this paper.

И■ The electrophysiological study of Ьга1д activity is an important field of psychophysiological research, in that it allows an on-line investigation qf cognitive processes. In this sense, during the last decade a number of studies investigated the relationship between ERPs and memory.

At different times before this critical moment, a third spot moved, indicating the side the lever should be tilted. The interval between the instant the direction was indicated and the instant the lever should be tilted varied randomly from 51 to 1071 ms. Clearly, for very short intervals (50–150 ms) responses in the direction indicated were 50% of the total (random performance), ...

One hypothesis that accounts for such links is that spatial attention operates upon representations of common locations in the external space. However, convincing evidence only exists for cross-modal links in spatial orienting, leaving the dynamics of these effects unexplored.

During a session of two hours, sixty EPs were recorded on the left and right cerebral hemispheres. The amplitude of N75-P100 component was measured. Remarkable variations were found with a periodicity from 15 to 60 min in six out of seven subjects. No hemispheric differences were found in the rhythmic variations. The results are in agreement with the behavioral data which show ultradian variations in visual performance depending on a general activation oscillator.
