Test-enhanced learning and transfer for tripleassociate word stimuli was assessed in three experiments. In each experiment, training and final-test trials involved the presentation of two words per triple associate (triplet), with the third word having to be retrieved. In agreement with the prior literature on different stimuli, training through testing with feedback yielded markedly better final-test performance than did restudy. However, in contrast to the positive transfer reported for paired associate stimuli, minimal or no positive transfer was observed, relative to a restudy control, from a trained cue combination (e.g., A, B, ?) to other cue combinations from the same triplet that required a different response (e.g., B, C, ?). That result also held when two unique cue combinations per triplet were tested during training, and for triplets with low and high average associative strengths. Supplementary analyses provided insight into the overall transfer effect: An incorrect response during training appears to yield positive transfer relative to restudy, whereas a correct response appears to yield no, or even negative, transfer. Crossexperiment analyses indicated that test-enhanced learning is not diminished when two or three cue combinations are presented during training. Thus, even though learning through testing is highly specific, testing on all possible stimulus-response combinations remains the most efficient strategy for the learning of triple associates.

To evaluate the electrochemical parameters of the reinforced concrete specimens at laboratory level there is no problem at all, because one can use any well-known electrochemical technique, but in site monitoring, there are few techniques being able to obtain these parameters. In this work a viable alternative is presented for the electrochemical evaluation of the reinforced concrete specimens in laboratory or in site monitoring. In order to have a reference of the corrosion rate obtained with the electrochemical noise technique and to be able to establish if these are real ones, measurements with commercial equipment were made applying the polarization resistance technique.Keywords: corrosion, electrochemical noise, polarization resistance, armed concrete, monitoring. IntroducciónEn la industria de la construcción, el hormigón armado con barras de acero es el material más empleado en todo el mundo, debido a su facilidad para moldearse y formar cualquier estructura geométrica, la corrosión del acero de refuerzo tiene una elevada frecuencia con que ocurre, por lo que puede decirse que la corrosión del acero del armado es una de las principales causas de que las estructuras de hormigón armado sufran deterioro prematuro.
