Many different cortical areas are thought to be involved in the process of selecting motor responses, from the inferior frontal gyrus, to the lateral and medial parts of the premotor cortex. The objective of the present study was to examine the neural underpinnings of motor response selection in a set of overt language production tasks. To this aim, we compared a sentence repetition task (exter...

We obtained behavioral data to evaluate two alternative hypotheses about the neural mechanisms of gaze control. The "fixation" hypothesis states that neurons in rostral superior colliculus (SC) enforce fixation of gaze. The "microsaccade" hypothesis states that neurons in rostral SC encode microsaccades rather than fixation per se. Previously reported neuronal activity in monkey SC during the s...

Studies of compound word processing have revealed effects of the compound's constituents in a wide variety of word production and comprehension tasks. Surprisingly, effects of the compound's constituents were not found in a recent word production study using the picture-naming task. Here, we examined whether these contrasting constituent effects reflect methodological differences or whether the...

We used fMRI to investigate competition during language production in two word production tasks: object naming and color naming of achromatic line drawings. Generally, fMRI activation was higher for color naming. The line drawings were followed by a word (the distractor word) that referred to either the object, a related object, or an unrelated object. The effect of the distractor word on the B...

Simply put, throughput is the amount of work that a computer or system of computers completes over a given interval of time. Increasing throughput is a constant demand placed on IT managers, researchers, and scientists. Increasing throughput might be accomplished by several different methods, but each method requires scheduling more tasks to machines in the system. However, scheduling tasks in ...

To investigate the influence of semantic/pragmatic variables on children's production of verb-phrase anaphora (VPA), a spoken sentence completion task (e.g., John is throwing a ball and ... Mary is too) was administered to four-, seven- and ten-year-olds. The frequency of VPA production was affected by whether the two clauses had the same or different polarity and by whether the actions were po...

In two experiments, we aimed to show the importance of task characteristics in scalar implicature production. In Experiment 1, we found that five-year-olds were significantly more pragmatic when given an Action-Based Task (ABT), in which they had to respond by performing an action than in a Truth-Value Judgement Task (TVJT), in which they had to evaluate the truth-value of statements. Experimen...

Few studies have been done examining noise exposures associated with agricultural tasks. This study was conducted to address that research gap by calculating the noise exposures for tasks and equipment associated with grain production and assessing the variability in those exposures. An additional aim of this study was to identify tasks and equipment that could be targeted for intervention stra...

this study explored the effect of contrastive phrase resynthesis instruction ongaining the teachability hypothesis stages in self-paced versus time-constrained oralproduction and recognition. three groups (i.e., 23 learners) of high beginner femalelearners in an english language institute were randomly selected from a cohort oflearners. one group received contrastive metalinguistic instruction ...

The phenomenon of meaning-preserving corrections given by an adult to a child involves several aspects: (1) the child produces an incorrect utterance, which the adult nevertheless understands, (2) the adult produces a correct utterance with the same meaning and (3) the child recognizes the adult utterance as having the same meaning as its previous utterance, and takes that as a signal that its ...
