Memory Processes

One conclusion from the literature on age differences in memory has been that primary memory processes are unaffected by advancing age. An exception to this generalization is the finding that material in primary memory is scanned more slowly with advancing age. Previous studies of this phenomenon, however, have yielded inconsistent results. In the present study we compared memory scanning rates of 12 young and 12 elderly subjects. There were no age differences in scanning speed or accuracy. The results support Craik's 1977 contention that primary memory processes are relatively unaffected by the aging process.

Our aim was to determine parameters of motor evoked potential (MEP) from the tongue in healthy persons.Methods. 25 healthy individuals (average age 22.4 ± 6.2 years, range 18–41 years, 12 females & 13 males) were enrolled. All underwent diagnostic TMS, single-pulse protocol, 90-sm round coil, Neiro-MS-D device. Coil was placed on Fz point, registration was performed by the surface electrode on the middle line of the tongue.Results. MEP was registered in all cases, its average latency was 7.14 ± 0.63 ms, average amplitude — 1.79 ± 1.09 μV. There were no gender & age differences.Conclusion. In healthy people aged 18–41 years MEP from the tongue may be registered in 100% of the cases; its average latency is 7.14 ± 0.63 ms, average amplitude — 1.79 ± 1.09 μV; there are no significant age & gender differences. TMS of the tongue according to this protocol is relatively simple, not time-and efforts-consuming & may be widely implemented in clinical neurophysiology.

Contralateral Ear

In studies which attempt to define the influence of various factors on recovery of hair cell integrity after acoustic trauma, an experimental and a control ear which initially have equal degrees of damage are required. With in a group of animals receiving an identical level of acoustic trauma there is more symmetry between the ears of each individual, in respect to function, than between animals. Figure 1 illustrates this, left and right cochlear evoked potential (CAP) audiograms are shown for two chinchillas receiving identical trauma. For this reason the contralateral ear is used as control.To compliment such functional evaluations we have devised a scoring system, based on the condition of hair cell stereocilia as revealed by scanning electron microscopy, which permits total stereociliar damage to be expressed numerically. This quantification permits correlation of the degree of structural pathology with functional changes. In this paper wereport experiments to verify the symmetry of stereociliar integrity between two ears, both for normal (non-exposed) animals and chinchillas in which each ear has received identical noise trauma.

Underlying Processes

Whereas subjective well-being remains relatively stable across adulthood, emotional experiences show remarkable short-term variability, with younger and older adults differing in both amount and correlates. Repeatedly assessed affect data captures both the dynamics and stability as well as stabilization that may indicate emotion-regulatory processes. The article reviews (1) research approaches to intraindividual affect variability, (2) functional implications of affect variability, and (3) age differences in affect variability. Based on this review, we discuss how the broader literature on emotional aging can be better integrated with theories and concepts of intraindividual affect variability by using appropriate methodological approaches. Finally, we show how a better understanding of affect variability and its underlying processes could contribute to the long-term stabilization of well-being in old age.

Abstract. Research on age differences in media usage has shown that older adults are more likely than younger adults to select positive emotional content. Research on emotional aging has examined whether older adults also seek out positivity in the everyday situations they choose, resulting so far in mixed results. We investigated the emotional choices of different age groups using video games as a more interactive type of affect-laden stimuli. Participants made multiple selections from a group of positive and negative games. Results showed that older adults selected the more positive games, but also reported feeling worse after playing them. Results supplement the literature on positivity in situation selection as well as on older adults’ interactive media preferences.
