We examined the emotional effects of (a) a rising versus a falling chromatic tone sequence in the background of audio news and (b) foreground versus background diatonic and chromatic tone sequences. In experiment one, 26 participants rated audio news messages with rising and falling chromatic background tone sequences on the valence and arousal dimensions. Cardiac activity, electrodermal activity (EDA), and facial muscle activity were also recorded continuously. In experiment two, 24 participants rated six plain tone sequences ( i.e., rising and falling chromatic, major, and minor) and six news messages with the aforementioned tone sequences mixed in the background on the valence and arousal dimensions. In experiment 1, both self-reported arousal and physiological arousal as measured by EDA were higher during the news with a rising-tone sequence compared to those with a falling-tone sequence. In experiment 2, rising-tone sequences prompted both higher arousal and pleasantness ratings. However, the responses were moderated by the type of listening task: foreground listening prompted responses related to musical connotations ( i.e., major tone sequences were rated as most pleasant and minor as most unpleasant), whereas background listening prompted responses dependent on the emotional congruence between the news messages and tone sequences ( i.e., the minor mode versions were rated as most pleasant and the major mode versions as most unpleasant). In addition, level of education-, music listening frequency-, and age-related differences in the responses were found and are discussed.

The Brain

Emerging evidence indicates that stimulus novelty is affectively potent and reliably engages the amygdala and other portions of the affective workspace in the brain. Using fMRI, we examined whether novel stimuli remain affectively salient across the lifespan, and therefore, whether novelty processing—a potentially survival-relevant function—is preserved with aging. Nineteen young and 22 older healthy adults were scanned during observing novel and familiar affective pictures while estimating their own subjectively experienced aroused levels. We investigated age-related difference of magnitude of activation, hemodynamic time course, and functional connectivity of BOLD responses in the amygdala. Although there were no age-related differences in the peak response of the amygdala to novelty, older individuals showed a narrower, sharper (i.e., “peakier”) hemodynamic time course in response to novel stimuli, as well as decreased connectivity between the left amygdala and the affective areas including orbito-frontal regions. These findings have relevance for understanding age-related differences in memory and affect regulation.

OBJECTIVE: To explore the possible differences in subjective analysis of the emotional stimuli from the International Affective Picture System between elderly and young samples. METHOD: 187 elderly subjects ranked the International Affective Picture System images according to the directions from the Manual of Affective Ratings. Their scores were compared to those obtained from International Affective Picture System studies with young people. RESULT: There is an age-related difference in arousal and valence in the International Affective Picture System rating. The correlation between affective valence and arousal is strong, and negative for the elderly. The expected versus the observed frequency of International Affective Picture System images between elderly and young samples show a statistical difference. CONCLUSION: This study shows an inter-age statistical dichotomy in how elderly and young people subjectively evaluate International Affective Picture System images.

The aim of the present research was to assess age-related differences in how children and adults interpret and visually process emotionally ambiguous neutral faces. Children and adults provided neutral child faces with valence and arousal ratings while eye movements were recorded. Consistent with previous research, children and adults both interpreted the neutral faces as negatively valenced. Both age groups showed fewer fixations to the eye region when they rated the faces as positive. However, adults fixated more on the eye region when they rated the faces as negative whereas children fixated more on the eye region when they rated the faces as neutral. This finding may suggest that children strategically allocate attentional resources to the eye region when processing emotionally ambiguous faces to gather critical affective information. These findings have implications for the utilization of neutral faces as an experimental control condition and serve as the foundation for future research on the development of mechanisms that underlie the interpretation of emotionally ambiguous faces.

The Way

Abstract Emotion concepts are representations that enable people to make sense of their own and others’ emotions. The present study, theoretically driven by the conceptual act theory, explores the overall spectrum of emotion concepts in older adults and compares them with the emotion concepts of younger adults. Data from 178 older adults (⩾55 years) and 176 younger adults (20–30 years) were collected using the Semantic Emotion Space Assessment task. The arousal and valence of 16 discrete emotions – anger, fear, sadness, happiness, disgust, hope, love, hate, contempt, guilt, compassion, shame, gratefulness, envy, disappointment, and jealousy – were rated by the participants on a graphic scale bar. The results show that (a) older and younger adults did not differ in the mean valence ratings of emotion concepts, which indicates that older adults do not differ from younger adults in the way they conceptualise how pleasant or unpleasant emotions are. Furthermore, (b) older men rated emotion concepts as more arousing than younger men, (c) older adults rated sadness, disgust, contempt, guilt, and compassion as more arousing and (d) jealousy as less arousing than younger adults. The results of the present study indicate that age-related differentiation of conceptual knowledge seems to proceed more in the way that individuals understand how arousing their subjective representations of emotions are rather than how pleasant they are.

Various inclusion bodies occur in vertebrate retinal photoreceptor cells. Most of them are membrane bound and associated with phagocytosis or they are age related residual bodies. We found an additional inclusion body in foveal cone cells of the baboon (Papio anubis) retina.The eyes of a 15 year old baboon were fixed by immersion in cacodylate buffered glutaraldehyde (2%)/formaldehyde (2%) as described in detail elsewhere . Pieces of retina from various locations, including the fovea, were embedded in epoxy resin such that radial or tangential sections could be cut.Spindle shaped inclusion bodies were found in the cytoplasm of only foveal cones. They were abundant in the inner segments, close to the external limiting membrane (Fig. 1). But they also occurred in the outer fibers, the perikarya, and the inner fibers (Henle’s fibers) of the cone cells. The bodies were between 0.5 and 2 μm long. Their central diameter was 0.2 to 0. 3 μm. They always were oriented parallel to the long axis of the cone cells. In longitudinal sections (Figs. 2,3) they seemed to have a fibrous skeleton that, in cross sections, turned out to consist of plate-like (Fig.4) and tubular profiles (Fig. 5).

Autophagy is a process of lysosome-dependent intracellular degradation that participates in the liberation of resources including amino acids and energy to maintain homoeostasis. Autophagy is particularly important in stress conditions such as nutrient starvation and any perturbation in the ability of the cell to activate or regulate autophagy can lead to cellular dysfunction and disease. An area of intense research interest is the role and indeed the fate of autophagy during cellular and organismal ageing. Age-related disorders are associated with increased cellular stress and assault including DNA damage, reduced energy availability, protein aggregation and accumulation of damaged organelles. A reduction in autophagy activity has been observed in a number of ageing models and its up-regulation via pharmacological and genetic methods can alleviate age-related pathologies. In particular, autophagy induction can enhance clearance of toxic intracellular waste associated with neurodegenerative diseases and has been comprehensively demonstrated to improve lifespan in yeast, worms, flies, rodents and primates. The situation, however, has been complicated by the identification that autophagy up-regulation can also occur during ageing. Indeed, in certain situations, reduced autophagosome induction may actually provide benefits to ageing cells. Future studies will undoubtedly improve our understanding of exactly how the multiple signals that are integrated to control appropriate autophagy activity change during ageing, what affect this has on autophagy and to what extent autophagy contributes to age-associated pathologies. Identification of mechanisms that influence a healthy lifespan is of economic, medical and social importance in our ‘ageing’ world.
