In a previous study, Parisse suggested that subject dislocations in French language (e.g. "la fille "elle" dort") could be considered as a marker of morphosyntactic development in children with normal language development. The present study aimed to develop this proposition and to confirm it with experimental data, more…

The authors argue that human sequential learning is often but not always characterized by a shift from stimulus- to plan-based action control. To diagnose this shift, they manipulated the frequency of 1st-order transitions in a repeated manual left-right sequence, assuming that performance is sensitive to frequency-induced biases under stimulus-…

This work presents a self-help, Internet-based telepsychology program for the treatment of public speaking fears. The system is comprised of 3 parts: The "assessment protocol" gives the patient information about his or her problem (i.e., amount of interference it creates in his or her life, severity, degree of fear and avoidance). The…

The authors studied the role of attention as a selection mechanism in implicit learning by examining the effect on primary sequence learning of performing a demanding target-selection task. Participants were trained on probabilistic sequences in a novel version of the serial reaction time (SRT) task, with dual- and triple-stimulus participants…

A study investigates recurrence relations, sequences in which each term is determined by one or more previous terms. Results provide another approach to the problem of finding closed forms for recursively-defined sequences.

Traditional education, employing lectures or telecommunicative instruction methods, has been very effective in providing topical facts. However, the development of student skills and thinking ability require higher levels of instruction and more opportunity to practice and apply acquired knowledge. As students progress through a particular…

In 2 experiments, the efficacy of motor imagery for learning to type number sequences was examined. Adults practiced typing 4-digit numbers. Then, during subsequent training, they either typed in the same or a different location, imagined typing, merely looked at each number, or performed an irrelevant task. Repetition priming (faster responses…

The production of complex sequences like music or speech requires the rapid and temporally precise production of events (e.g., notes and chords), often at fast rates. Memory retrieval in these circumstances may rely on the simultaneous activation of both the current event and the surrounding context (Lashley, 1951). We describe an extension to a…

The journey children make from tube feeding to oral feeding is personal for each child and family. There is a sequence of predictable plateaus that children climb as they move toward orally eating. By better understanding this sequence, parents and children can maximize the development, learning, enjoyment and confidence at each plateau. The…

The present study attempted to demonstrate that subjects do attend to and abstract complex contingencies between events in probabilistic, nondeterministic schedules. (Authors)

Three severely retarded children (8 and 16 years old) were taught to point to consonant/vowel/consonant nonsense labels depicted by geometric forms under both serial (in which training was in one item at a time) and concurrent (in which training was in three items at a time) training conditions. (Author)

Target location probability was manipulated in a visual search task. When the target was twice as likely to appear on 1 side of the display as the other, manual button-press response times were faster (Experiment 1A) and first saccades were more frequently directed (Experiment 1B) to the more probable locations. When the target appeared with equal…

Behavior analysts have offered accounts of the behavior involved in matching to sample and delayed matching to sample. But until recently have not offered a behavioral analysis of generalized matching-to-sample. The concept of joint control, however, seems especially suited to such an analysis The present study used a joint-control procedure to…
