“…The experiments reported here provide additional cases in which memories established in the radial maze persisted beyond trial termination (Roberts & Dale, 1981) and also confirm earlier reports of the rather long duration of such memories Maki et al, in press). It now appears that memories of visits to arms in the radial maze last for at least as long between trials as they do within trials (cf.…”

“…More recent research, however, has demonstrated substantial PI, suggesting that working memory for locations within the maze persists between trials. Roberts and Dale (1981) reported that performance deteriorated with repeated radial maze trials. After using a two-choice discrimination task in the radial maze, reported fewer accurate choices after a 5-h ITI than after a 19-h Copyright 1986 Psychonomic Society, Inc.…”

“…Maki et al (in press) suggested that PI could occur for at least two reasons. One source of PI could be a failure of recency discrimination (D ' Amato, 1973;Roberts & Dale, 1981;Staddon, 1983, pp. 376-389); the rat could have trouble discriminating memories of visits to different locations at different times.…”

Rats were trained in 8-and 12-arm radial mazes. Each trial began with a study phase (forced choices of 4 arms). The trial ended after a 2-h delay in a test phase consisting of free choices among 8 arms; choices of the 4 arms not yet visited were correct (rewarded). Proactive interference (PI) was induced by an interference phase that occurred on some days 2 or 3 h prior to the study phase. In the PI-repetition condition, the interference phase consisted of forced choices of the 8 arms that were later presented in the study and test phases; in the PI-nonrepetition condition, the interference consisted of forced choices of the 4 arms that were correct during the test phase. Test-phase performance was most accurate in the No PI (single-trial) condition and least accurate in the PI-repetition condition. A second experiment showed that repetitions per se were not responsible for the PI; when the interference phase consisted only of choices of the same 4 arms later presented in the study phase, no PI was observed. These findings suggest two sources of PI. One source, measured by the difference between No PI and PI-nonrepetition conditions, appears to be a difficulty in discriminating the temporal order of visits to arms in the interference and study phases. The other source of PI, measured by the difference between the nonrepetition and repetition conditions, remains to be identified; some possibilities are discussed.

“…High degrees of response stereotypy commonly occur when rats are tested on the radial maze: in particular, subjects choose sequences of adjacent arms [5,7,10,15,17,22,24,26]. Similar response patterning has been observed in Betta splendens [19], pigeons [2,18], mice [6,16], gerbils [25], and children [1].…”

“…Subjects rapidly attain high choice accuracy, learning to collect all eight pieces of food in only eight or nine choices. Although response strategies, such as choosing adjacent arms in a clockwise order, are not necessary for accurate choice on the radial maze (Olton, Collison, & Werz, 1977;Roberts & Dale, 1981), response patterning is prevalent in radial maze research (Dale, 1982;Einon, 1980;Foreman, 1985). In the present experiment, we examined both choice accuracy and response patterns on the radial maze.…”

Four groups of rats were tested on an eight-arm radial maze under a free-choice procedure. The subjects were maintained at either 80% or 100% of their preexperimental free-feeding weights through restricted access to either food or water. Water-deprived subjects received water in the maze; food-deprived subjects received food. Water-deprived subjects learned the task faster than food-deprived subjects. The four groups developed different response patterns. These were measured by the mean transition size, the average angular distance (in 45°units) between consecutively chosen arms. Rats foraging for food and water developed different search strategies, with water-deprived subjects exhibiting lower mean transition sizes. When the subjects were given three consecutive trials, 2 min apart, choice accuracy declined across trials, although performance on the last two trials improved across days. The groups' mean transition sizes remained different, and were constant over trials and days. Thus, the test procedures differentially affected choice accuracy and response patterning.
