“…Notably, the neural source of N2b was shown to be in the anterior frontal lobes, more specifically in the anterior cingulate cortex (for a review, see Mulder et al, 1995) and the same structure was identified as being implicated in cardiac slowing (Powell, Buchanan, & Gibbs, 1990), for example, in a visual attention task (Nobre et al, 1997). As to the effect of aging, it is well established that evoked cardiac deceleration is diminished in elderly people (Friedman, Putnam, & Hamburger, 1990; Podlesny & Dustman, 1982).…”

Our aim was to study age-related differences in the habituation of orienting reaction by using novel visual stimuli. We intended to fill a gap in habituation research by recording both autonomic and ERP components of orienting to visual stimuli in the same sample and in highly related paradigms. We report data showing that in young subjects repetition of visual novels yielded fast habituation of both skin conductance responses and ERP components (P3(novel), N2b) whereas elderly people displayed no sign of habituation. However, cardiac deceleration--thought conventionally to be part of the orienting reaction--did not habituate in either group. Overall, most of our results harmonize with those obtained by using auditory stimuli; therefore we conclude that there is no significant modality specificity in age-related deterioration of habituation processes.

It relies upon the fact that, for example, as children mature, their information processing capabilities improve (cf., Bruner, Olver & Greenfield, 1966), presenting the possibility for differences between age groups to be anchored in such (specifiable) age-related changes in cognitive skill.…”

Comparison of the results of the studies of cognitive development and normal aging suggests a large degree of commonality in both behavioral and ERP effects across a wide age range. Whether measured in young children, adolescents, young, middle-aged or elderly adults, the size of the ERP repetition effect did not differ among the various age groups. This was true whether memory was tested directly during continuous recognition or indirectly during variants of semantic categorization tasks. Similarly, in the studies of adult aging, the degree of RT facilitation during the semantic task did not differ with age and, in both the studies of cognitive development and aging, the degree of RT prolongation during the explicit tasks did not appear to differ as a function of age. Moreover, in the studies of adult aging, the effects of three versus two exposures of a word assessed in the PM session (TABLE 1), modulated RT similarly in all three age groups. These data argue for continuity of information processing across a very wide age range during both direct and indirect memory tasks, when retention is assessed during the recognition (for explicit testing) and repetition (for implicit testing) phases of the task. Since ERP and RT modulation do not appear to differ with age during the retrieval phases of these experiments, how can the performance differential seen in young children and older adults be explained? Some evidence comes from the ERP data recorded during the study phases of our explicit tasks. During continuous recognition, both young children and elderly adults did not show the typical subsequent "memory effect." In the case of the children, the subsequently unrecognized ERP was larger than the subsequently recognized ERP, whereas for the older adults, there was no difference between these two ERPs. Moreover, during these same tasks, the young children did show the "crossover" (new greater than old) pattern for slow wave activity, whereas the older adults did not. Since these ERP findings were obtained during the acquisition phase (i.e., to new items that had to be encoded for subsequent retrieval), the data argue for encoding difficulties as one means of explaining the performance differences seen at the two ends of the age spectrum. However, since the older adults displayed a different new/old pattern for slow wave activity, the two age groups may differ qualitatively in the strategies employed to encode items for subsequent retrieval.(ABSTRACT TRUNCATED AT 400 WORDS)

“…Maternal decelerations can even mimic the shapes of early, variable, and late fetal decelerations (see Figure 4). Although limited, research has found that the etiology of maternal decelerations is likely multifactorial and includes unpleasant cognitive stimuli, emotions, muscle tensing, and/or hypertension-baroreceptor activationvagal stimulation (Ford, Scholey, Ayre, & Wesnes, 2002;Friedman, Putnam, & Hamberger, 1990;Jennings, van der Molen, Somsen, & Brock, 1991;Palomba, Sarlo, Angrilli, Mini, & Stegagno, 2000;Zimmer, Vossel, & Frohlich, 1990). Caffeine ingestion may limit the depth of decelerations.…”
