Aging, Emotion, Attention, and Binding in the Taboo Stroop Task: Data and Theories.

How does aging impact relations between emotion, memory, and attention? To address this question, young and older adults named the font colors of taboo and neutral words, some of which recurred in the same font color or screen location throughout two color-naming experiments. The results indicated longer color-naming response times (RTs) for taboo than neutral base-words (taboo Stroop interference); better incidental recognition of colors and locations consistently associated with taboo versus neutral words (taboo context-memory enhancement); and greater speed-up in color-naming RTs with repetition of color-consistent than color-inconsistent taboo words, but no analogous speed-up with repetition of location-consistent or location-inconsistent taboo words (the consistency type by repetition interaction for taboo words). All three phenomena remained constant with aging, consistent with the transmission deficit hypothesis and binding theory, where familiar emotional words trigger age-invariant reactions for prioritizing the binding of contextual features to the source of emotion. Binding theory also accurately predicted the interaction between consistency type and repetition for taboo words. However, one or more aspects of these phenomena failed to support the inhibition deficit hypothesis, resource capacity theory, or socio-emotional selectivity theory. We conclude that binding theory warrants further test in a range of paradigms, and that relations between aging and emotion, memory, and attention may depend on whether the task and stimuli trigger fast-reaction, involuntary binding processes, as in the taboo Stroop paradigm

Memory for Emotionally Provocative Words in Alexithymia: A Role for Stimulus Relevance

Alexithymia is associated with emotion processing deficits, particularly for negative emotional information. However, also common are a high prevalence of somatic symptoms and the perception of somatic sensations as distressing. Although little research has yet been conducted on memory in alexithymia, we hypothesized a paradoxical effect of alexithymia on memory. Specifically, recall of negative emotional words was expected to be reduced in alexithymia, while memory for illness words was expected to be enhanced in alexithymia. Eighty-five high or low alexithymia participants viewed and rated arousing illness-related ( pain ), emotionally positive ( thrill ), negative ( hatred ), and neutral words ( horse ). Recall was assessed 45 min later. High alexithymia participants recalled significantly fewer negative emotion words but also more illness-related words than low alexithymia participants. The results suggest that personal relevance can shape cognitive processing of stimuli, even to enhance retention of a subclass of stimuli whose retention is generally impaired in alexithymia

Experiencing discrimination increases risk taking.

Prior research has revealed racial disparities in health outcomes and health-compromising behaviors, such as smoking and drug abuse. It has been suggested that discrimination contributes to such disparities, but the mechanisms through which this might occur are not well understood. In the research reported here, we examined whether the experience of discrimination affects acute physiological stress responses and increases risk-taking behavior. Black and White participants each received rejecting feedback from partners who were either of their own race (in-group rejection) or of a different race (out-group rejection, which could be interpreted as discrimination). Physiological (cardiovascular and neuroendocrine) changes, cognition (memory and attentional bias), affect, and risk-taking behavior were assessed. Significant participant race × partner race interactions were observed. Cross-race rejection, compared with same-race rejection, was associated with lower levels of cortisol, increased cardiac output, decreased vascular resistance, greater anger, increased attentional bias, and more risk-taking behavior. These data suggest that perceived discrimination is associated with distinct profiles of physiological reactivity, affect, cognitive processing, and risk taking, implicating direct and indirect pathways to health disparities

Does a brief mindfulness intervention counteract the detrimental effects of ego-depletion in basketball free throw under pressure?

Research has shown that a brief mindfulness intervention may counteract the depleting effects of an emotion suppression task upon a subsequent psychological task that requires self-control. However, the effects of a brief mindfulness intervention on perceptual–motor tasks particularly in stressful situations have not yet been examined. The purpose of this study was to investigate whether a brief mindfulness intervention can counteract the detrimental effects of ego-depletion in basketball free throw performance under pressure. Seventy-two basketball players (mean age = 28.6 ± 4.0 yrs) were randomly assigned to one of the following 4 groups: depletion/mindfulness, no depletion/mindfulness, depletion/no mindfulness and control (no depletion/no mindfulness). The mindfulness intervention consisted of a 15-min breathe and body mindfulness audio exercise, while the control condition (no mindfulness) listened to an audio book. A modified Stroop color-word task was used to manipulate self–control and induce ego depletion. Participants performed 30 free throws before and after the experimental manipulations. Results showed that basketball players’ free throw performance decreased after ego-depletion, but when ego-depletion was followed by the mindfulness intervention, free throw performance was maintained at a level similar to the control group. Our results indicate that a brief mindfulness intervention mitigates the effects of ego depletion in a basketball free-throw task

Signals of threat do not capture, but prioritize, attention: a conditioning approach

Research suggests that threatening information captures attention more rapidly than neutral information. However, in most studies threat stimuli differ perceptually from neutral stimuli and are instrumental to perform the task, leaving the question unanswered whether threat is sufficient to capture attention. In experiment 1, we designed a visual search task with stimuli of equal salience (colored circles) that have the potential to lead to efficient search (10 ms/item). In experiment 2, one of the colors (conditioned stimulus, CS+) was made threatening by means of fear conditioning. Participants responded to a target presented in one of the circles. Overall, the search was faster on congruent trials (where the target was presented in the CS+) than on baseline trials (where the CS + was absent). Furthermore, the search was slower on incongruent trials (where the target was presented in another color than the CS+) than on baseline trials. The search on congruent trials was affected by set size (90 ms/item), but to a lesser extent than on baseline trials (105 ms/item). We conclude that threat prioritizes, but does not capture attention

The positivity effect in older adults : the role of affective interference and inhibition

Objectives: Research shows that aging often involves a decrease in the experience of negative affect and might even be associated with a stabilization or an increase in experience concerning positive affect. As it has been suggested that these changes could be related to the processing of emotional information, the aim of this study was to investigate interference and inhibition toward sad and happy faces in healthy elderly people compared to a younger population. Method: We used an affective modification of the negative priming task. If interference is related to enhanced inhibition, reduced interference from negative stimuli and a related weakened inhibition toward negative stimuli in the elderly group would be in line with the positivity hypothesis. Results: As expected, the results indicated that interference from negative stimuli was significantly lower in older adults as compared to younger adults, whereas this was not the case for positive stimuli. Moreover, at inhibitory level a significantly reduced processing of negative stimuli was observed only in the older adult group, whereas there was no such effect in the case of positive material. Conclusion: These observations are indicative for a decreased negative bias in older adults at information processing level. This provides new insights with regard to age-related differences in emotion processing

Processing advantage for emotional words in bilingual speakers

Effects of emotion on word processing are well established in monolingual speakers. However, studies that have assessed whether affective features of words undergo the same processing in a native and non-native language have provided mixed results: studies that have found differences between L1 and L2 processing, attributed it to the fact that a second language (L2) learned late in life would not be processed affectively, because affective associations are established during childhood. Other studies suggest that adult learners show similar effects of emotional features in L1 and L2. Differences in affective processing of L2 words can be linked to age and context of learning, proficiency, language dominance, and degree of similarity between the L2 and the L1. Here, in a lexical decision task on tightly matched negative, positive and neutral words, highly proficient English speakers from typologically different L1 showed the same facilitation in processing emotionally valenced words as native English speakers, regardless of their L1, the age of English acquisition or the frequency and context of English use
