Recent methodological advances have allowed researchers to address confounds in the measurement of task-switch costs in task-switching performance by dissociating cue switching from task switching. For example, in the transition-cuing procedure, which involves presenting cues for task transitions rather than for tasks, cue transitions (cue…

Implicit sequence learning, as measured using the sequential reaction time (SRT) task paradigm originally introduced by Nissen & Bullemer (1987), has been reported to be impaired in high-functioning individuals with autism (Mostofsky, Goldberg, Landa, & Denckla, 2000). We reasoned that increased exposure to the sequence may particularly benefit…

Through the use of a new serial naming task, the authors investigated implicit learning of repeating sequences of abstract semantic categories. Participants named objects (e.g., table, shirt) appearing in random order. Unbeknownst to them, the semantic categories of the objects (e.g., furniture, clothing) followed a repeating sequence.…

We investigated infants' sensitivity to spatiotemporal structure. In Experiment 1, circles appeared in a statistically defined spatial pattern. At test 11-month-olds, but not 8-month-olds, looked longer at a novel spatial sequence. Experiment 2 presented different color/shape stimuli, but only the location sequence was violated during test;…

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 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…

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…

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…

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…

Introduction: Innovative technology has led to high-precision radiation therapy that has dramatically altered the practice of radiation oncology. This qualitative study explored the implementation of this innovation into practice from the perspective of the practitioners in a large academic radiation medicine program and aimed to improve…

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.

Competence in algebra is linked to access to higher education, employment in better-paying jobs, and, increasingly, the ability to earn a high school diploma. For many students with learning disabilities, developing proficiency in algebra represents a challenging, but necessary goal. Teachers of students with learning disabilities need access to…

The method of scoring is used to obtain maximum likelihood estimates of the parameters in White and Clark's (EJ 075 122) learning hierarchy validation model. From the proportion of the population possessing only the superordinate skill in a pair of hierarchical skills, and its variance, the hypothesis of inclusion is tested. (Author/CTM)

On cyclic-interval reinforcement schedules, animals typically show a postreinforcement pause that is a function of the immediately preceding time interval ("temporal tracking"). Animals, however, do not track single-alternation schedules--when two different intervals are presented in strict alternation on successive trials. In this experiment,…

This study examined the ability of 59 2- and 3-year-old children to monitor goal-directed activities with respect to an anticipated outcome. The study focused on two skills: error monitoring and error avoidance through anticipatory monitoring. To elicit monitoring, a variety of simple tasks were presented to the children. In each, a successful…
