Item Recognition (Sternberg, 1966) is a task which reflects the operation of human memory. This task was considered as a candidate for use in a battery of Performance Evaluation Tests for Environmental Research (PETER). Environmental research involves comparison of performances in a baseline environment and in a novel environment. It is desirable that scores be stable at different occasions in the baseline environment, so that changes due to the novel environment will be clear if they occur. It was found that item recognition results were similar to those obtained by other investigations, although the traditional item recognition score (slope) was unreliable across repeated measurements. The response time (RT) was stable for each of the four memory set sizes (1, 2, 3 & 4 items), from the standpoint of reliability, after the fourth session.

Listed are 90 reports of the Performance Evaluation Tests for Environmental Research (PETER) Program. Conducted from 1977 to 1982, the programs' purpose was to develop a test battery for use in repeated measures investigations of environmental effects on human performance, e.g., vehicle motion, toxic substances, aging, etc. The battery also has applications to training, selection, and research on equipment design. The PETER Program concentrated on selecting tests which remained stable with repeated measurements, as environmental research usually involves testing before, during, and after exposure. Stability of the means, variances, and intertrial correlations ensures that simple analyses may be applied with minimal complications and without difficulties of attribution of effect. Over 80 measures were evaluated, 30% were found suitable for repeated measures applications, 20% were acceptable for limited use, and 50% could not be recommended. The unsuitability of many tasks brings into question the validity of portions of the literature on environmental effects. The reports describe program rationale, development of statistical methodology, and stable tasks. PETER reports are available from published sources, authors, or the Naval Biodynamics Laboratory.

Auditory digit span was evaluated as an instrument for repeated measurements experimentation. Twelve subjects were tested for one hour on each of 12 consecutive workdays in a standard environment. Both forward and backward digit span were measured. It was found that forward digit span was suitable for repeated measures after ten days of practice at 30 minutes per day. The criteria for suitability were predictability of the mean scores, constancy of the standard deviations and differential stability of the intertrial correlations. These criteria are sufficient conditions both for repeated measures Analysis of Variance, and for interpretation of experimental effects. Although the backward digit span scores did not meet these criteria, they became more and more correlated with the forward digit span scores as the experiment progressed. This indicates that the mental content of the two tests of memory converged with practice. One implication of this finding is to question the meaningfulness of factor structure after only limited practice. The forward auditory digit span test was recommended for inclusion in a battery of Performance Evaluation Tests for Environmental Research (PETER).

Michel Butor, born in 1926, one of the leaders of the French New Novel movement, has written only four novels between 1954 and 1960. The most famous of them is La Modification (Second thoughts), published in 1957. The author of the paper analyzes two other Butor’s novels: L’Emploi du temps (Passing time) – 1956, and Degrés (Degrees) – 1960. The theme of absence is crucial in both of them. In the former, the novel, presented as the diary of Jacques Revel, a young Frenchman spending a year in Bleston (a fictitious English city vaguely similar to Manchester), describes the narrator’s struggle to survive in a double – spatial and temporal – labyrinth. The first of them, formed by Bleston’s streets, squares and parks, is symbolized by the City plan. During his one year sojourn in the city, using its plan, Revel learns patiently how to move in its different districts, and in its strange labyrinth – strange because devoid any centre – that at the end stops annoying him. The other, the temporal one, symbolized by the diary itself, the labyrinth of the human memory, discovered by the narrator rather lately, somewhere in the middle of the year passed in Bleston, becomes, by contrast, more and more dense and complex, which is reflected by an increasinly complex narration used to describe the past. However, at the moment Revel is leaving the city, he is still unable to recall and to describe the events of the 29th of February 1952. This gap, this absence, symbolizes his defeat as the narrator, and, in the same time, the human memory’s limits. In Degrees temporal and spatial structures are also very important. This time round, however, the problems of the narration itself, become predominant. Considered from this point of view, the novel announces Gerard Genette’s work Narrative Discourse and his theoretical discussion of two narratological categories: narrative voice and narrative mode. Having transgressed his narrative competences, Pierre Vernier, the narrator of the first and the second parts of the novel, who, taking as a starting point, a complete account of one hour at school, tries to describe the whole world and various aspects of the human civilization for the benefit of his nephew, Pierre Eller, must fail and disappear, as the narrator, from the third part, which is narrated by another narrator, less audacious and more credible.
