PURPOSE Delayed auditory feedback (DAF) of a speaker's voice disturbs normal speech production. Various traditional theories assume that the content of the delayed feedback signal interferes with the actual production of a particular speech unit (phonemic content hypothesis). The displaced rhythm hypothesis as an alternative explanation suggests that speech(More)
Three experiments investigated the influence of a non-consciously perceived visual signal on motor reaction time when subjects were exposed to a stimulus contingency according to the general rules of the Pavlovian conditioning procedure. Conscious perception was prevented by meta-contrast backward masking. A total of 128 adult subjects had to discriminate(More)
This study investigated tadpole self-drawings from 183 three- to six-year-old children living in seven cultural groups, representing three ecosocial contexts. Based on assumed general production principles, the influence of cultural norms and values upon specific characteristics of the tadpole drawings was examined. The results demonstrated that children(More)
The role of Pavlovian contingencies in human skilled motor behavior was investigated in three experiments by means of a new conditioning preparation. In Experiment 1 the present method was shown to be appropriate for the study of associative learning. Subjects who experienced a standard delay configuration performed significantly more conditioned responses(More)
The present 2 x 2 study deals with the influence of controllability and predictability of an aversive noise stimulus on a subsequent learning task. Eighty-four subjects participated in two experiments. In correspondence with the concept of learned helplessness, controllability was shown to be the dominant factor in the first experiment. In the second(More)
