当一个与目标词在图形上相似的启动语促进了目标词的加工时，就会发生形式启动。在激活模型（如莫顿的logogen模型）中，这种效应可以解释为部分激活效应。一个与目标有相同字母的质数必然会在质数和目标的探测器中产生激活。或者，形式启动可以被看作是重复启动的一种特殊情况，在这种情况下，启动者实际上访问了目标的条目。结果表明，在词汇判断任务中，掩蔽启动效应可以获得的图形相关的对，如bontrast-CARST，但没有四个字母对，如bamp-CAMP。结果表明，启动效应受相邻词密度的控制，短词的相邻词多，长词的相邻词少。这一假设是支持的发现，形式启动发生四个字母的单词，如果总理和目标是从低密度的街区。对于部分激活理论，抑制机制，是敏感的素数邻居的数量需要解释的结果。在所考虑的几个版本的重复帐户中，“最佳匹配”假设似乎是最有希望的：这假设启动仅限于与启动最匹配的刺激。它还表明，在形式和意义（例如，制造，使）相关的启动目标对产生相同的启动效果，如预测的重复帐户，假设一个共同的条目下的两种形式。
Form-priming occurs when a prime that is graphemically similar to the target word facilitates processing of the target. In an activation model (such as Morton''s logogen model), such an effect can be interpreted as a partial-activation effect. A prime that shares letters with the target must inevitably produce activation in the detectors for both the prime and the target. Alternatively, form-priming could be seen as a special case of repetition-priming, in which the prime actually accesses the entry for the target. It is shown that masked-priming effects in the lexical decision task can be obtained for graphemically related pairs such as bontrast-CONTRAST, but not for four-letter pairs such as bamp-CAMP. It is suggested that the priming effect is controlled by neighbourhood density, shorts words usually having many neighbours, long words having very few. This hypothesis is supported by the finding that form-priming does occur for four-letter words if the prime and target are drawn from low-density neighbourhoods. For a partial-activation theory, an inhibitory mechanism that is sensitive to the number of prime-neighbours is required to explain the results. Of the several versions of a repetition account considered, the "best match" hypothesis appears to be the most promising: this assumes that priming is limited to the stimulus that best matches the prime. It is also shown that prime-target pairs that are related in form and meaning (e.g. made-MAKE) produce the same priming effect as identical pairs, as predicted by a repetition account that assumes a common entry underlying both forms.
