Objective and subjective measures indicate that orthographically similar words produce a blocking experience.
Memory blocks are a common experience characterised by inappropriate retrieval of information that impairs memory search processes. In five studies, memory blocks were induced via exposure to orthographically similar words (Smith & Tindell, 1997) while participants reported their subjective experiences to determine whether the memory block effect (MBE) paradigm produces a feeling of being blocked. Experiments 1 and 3 provided evidence that the MBE is associated with more blocked experiences. In Experiments 2 and 4 increased blocking experiences correlated with blocked fragments when the experimental manipulation was disguised, which demonstrates that ratings were not contaminated by demand characteristics. Experiment 5 demonstrated that blocking happens even when there is no study list. Collectively, the subjective retrieval ratings and the objective response data provide converging evidence that exposure to orthographically similar words induces a memory block characterised by an ineffective memory search that perseverates on interfering information.
