The purpose of this study was to investigate the effect of covert rehearsal and the characteristics of the response biasings by interpolated mental activities in- short-term retention of isometric force information. The dependent variables were the percent constant error (PCE) and the percent absolute error (PAE) made by 264 male undergraduate students who attempted to reproduce a criterion force of either 7 kg, 15 kg, or 23 kg during immediate (5 dec.) and delayed (30 sec.) recall tests. The order of administration of the recall tests was counterbalanced across subjects. The 30-sec retention intervals were filled with either covert rehearsal, overt backwards-counting, covert backwards-counting, or resting without rehearsal. The results are summarized as follows: 1) It was found that there was no forgetting over time when the covert rehearsal strategy was used during the retention interval. 2) The vividness scores of kinesthetic imagery during covert rehearsal significantly correlated with the PCE in delayed recall test. These findings suggest that the force information can be centrally processed and decays very little during a retention interval if covert rehearsal strategy is used. 3) The PCE in both criterion forces of 15kg and 23kg significantly shifted in the negative direction over time for the resting condition, while the PCE in both criterion forces of 7kg and 23kg was significantly shifted in the positive direction when the interval was filled with the overt counting. 4) The PCE in the covert backwards-counting condition was less positive than that in the overt counting condition, and was more positive than that in the resting condition. These findings appear to support a dual-process theory by Pepper and Herman involving decay and interference features so that they account for response biasing by interpolated mental activity in short-term memory of force information.
