- Several studies indicate that the recollection process, as assessed by the Remember-Know paradigm (Tulving, 1985) is enhanced for emotional stimuli as compared with neutral ones. The goal of this study was to assess the influence of emotion on recollection process, applying the Processes Dissociation Procedure (PDP; Jacoby, 1991) on emotional and neutral pictures. A total of 63 participants (aged 40-78 years) were included in this study, and the PDP was implemented by a list discrimination task. The results indicate that recollection estimate is lower for positive and negative pictures compared with neutral ones. This finding contrasts with others using the Remember-Know procedure (e.g., Ochsner, 2000) but is in agreement with the previously described trade-off effect (e.g., Jurica and Shimamura, 1999).

- This study examined age differences in phasic heart rate in response to neutral, negative and positive pictures. Heart rate changes and subjective ratings were analyzed in 22 middle-aged (40-55 years) and 30 older (56-78 years) participants. The effects of valence on the HR pattern across time were similar to that obtained by Bradley and co-workers. Conversely to previous studies, we did not report any age-related reduction in cardiac reactivity. Instead, when viewing positive pictures, the triphasic wave form appeared in the group of older adults, but for younger participants, it was replaced by a sustained deceleration. These results were interpreted in the light of the socioemotional selectivity theory.

Effect of Normal Aging on Emotional Processing and Impact of Emotion on Memory : Psychophysiological and Cognitive Findings
- 2006

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- It has long been thought that aging is accompanied by an emotional flattening. Although a different view has started to emerge recently, studies investigating psychophysiological responses in reaction to affective stimuli so far have reported an age-related reduction of the affective response. One of the main goals of this thesis was to revisit this issue by examining subjective reports, phasic heart rate, skin conductance (SCR) and facial electromyography (EMG) in response to a set of neutral and emotional pictures in a group of middle-aged participants (40-55 yrs), as compared with a group of older participants (56-78 yrs). A second main goal was to examine the effect of emotion on memory recollection and familiarity, using a Process Dissociation Procedure (PDP; Jacoby, 1991). In paper I, heart rate changes and reports of emotional experiences when viewing pictures were analysed in middle-aged and older participants. Consistent with previous findings, the results showed a clear differentiation of the heart rate changes as a function of time and picture type. Specifically, aversive pictures gave rise to the steepest initial heart rate deceleration and positive pictures elicited the greatest mid-interval acceleration, the latter being observed only in older participants. Parallel to this finding, older persons rated the positive pictures as being more pleasant than the younger did. The results were in agreement with other recent findings showing that older adults, preferentially pay attention to, and better retrieve positive information as compared with younger. Paper II reported the effects of age and gender on subjective reports, SCR and facial EMG. The effect of gender on subjective reports and psychophysiological measures was consistent with previous studies. No effect of age was found; the response magnitude for affective pictures was of similar size as that of younger adults. However, the gender differences on SCR and facial corrugator electromyography were absent in the group of older persons. The general conclusion that emerged from these two studies is that aging is not associated with a general decline of the emotional response. Nevertheless, the present results indicate that gender-related differences are attenuated in older individuals. Paper III examined the effects of emotion on recollection and familiarity, using a PDP implemented by a list discrimination task. The results revealed a detrimental effect of emotion on recollection process but not on familiarity. The finding was interpreted in the light of the trade-off hypothesis, predicting a memory enhancement of emotion for central information and a compromised effect for irrelevant or background details.
