Impaired Children

This study investigated the dimensional knowledge evidenced by language impaired (LI) preschoolers. Ten LI and 10 language normal (LN) children, aged 3:6 to 5:9, were asked to solve verbal and nonverbal problems requiring color and size judgments. There were no group differences on the verbal task, but the LI children performed less well than the LN children on the nonverbal task. Much of this difference stemmed from their difficulty with size items. The ordinal nature of the size dimension implies greater cognitive processing demands than are inherent in nominal dimensions such as color. Given the known processing limitations of language impaired children, this complexity apparently can lead to erroneous judgment even when requisite knowledge is present. It may also contribute to delays in the initial construction of dimensional knowledge.

Abstract The distribution of attention between competing processing demands can have dramatic real-world consequences, however little is known about how limited attentional resources are distributed during real-world behaviour. Here we employ mobile EEG to characterise the allocation of attention across multiple sensory-cognitive processing demands during naturalistic movement. We used a neural marker of attention, the Event-Related Potential (ERP) P300 effect, to show that attention to targets is reduced when human participants walk compared to when they stand still. In a second experiment, we show that this reduction in attention is not caused by the act of walking per se. A third experiment identified the independent processing demands driving reduced attention to target stimuli during motion. ERP data reveals that the reduction in attention seen during walking reflects the linear and additive sum of the processing demands produced by visual and inertial stimulation. The mobile cognition approach used here shows how limited resources are precisely re-allocated according to the sensory processing demands that occur during real-world behaviour.

Prospective Memory Performance

Prospective memory performance as a measure of everyday cognitive functioning is of increasing importance for developmental research. However, comparisons of studies on prospective memory development in adults reveal essential differences. Although some studies report no age effects, others find age effects of widely varying magnitudes. We suggest that differences in these findings on prospective memory performance can be explained by an age by task interaction (i.e., large amounts of cognitive load imposed by time-based prospective memory tasks disproportionally penalise older adults who possess fewer cognitive resources). We explored our hypothesis in a study with 90 young adults (M = 24.0 years) and 75 older adults (M = 69.0 years) by manipulating the overall cognitive processing demands of the prospective task situation. We varied the cognitive load of the background task while holding constant the time-based prospective memory task. Results indicate that the effects of increased overall processing demands strongly influence older adults’ performance. Results are discussed within the framework of capacity explanations of cognitive ageing that focus on the role of working memory resources in monitoring processes.
