The influence of emotional valence on age differences in early processing and memory.

This study examined older and younger adults' attentional biases and subsequent incidental recognition memory for distracting positive, negative, and neutral words. Younger adults were more distracted by negative stimuli than by positive or neutral stimuli, and they correctly recognized more negative than positive words. Older adults, however, attended equally to all stimuli yet showed reliable recognition only for positive words. Thus, although an attentional bias toward negative words carried over into recognition performance for younger adults, older adults' bias appeared to be limited to remembering positive information.

Binocular rivalry and the study of identification in asthmatic and nonasthmatic boys.

Describes a method for studying motivational properties of identification in a group of 55 8-11 yr. old asthmatic and nonasthmatic boys. Selective attention of a child toward his mother or father was measured by the child's resolution of a binocular rivalry test in which the competing stimuli were photographs of the child's own parents. Perceptual dominance scores derived from this test were then examined in relation to certain other perceptions of the child. Split-half reliability of perceptual dominance scores was .84. Perceptual dominance of the father was positively related to perceived power of the father among nonasthmatic boys (r = .37, p     

Here is looking at you: Emotional faces predominate in binocular rivalry.

Two incompatible pictures compete for perceptual dominance when they are presented to one eye each. This so-called binocular rivalry results in an alternation of dominant and suppressed percepts. In accordance with current theories of emotion processing, the authors' previous research has suggested that emotionally arousing pictures predominate in this perceptual process. Three experiments were run with pictures of emotional facial expressions that are known to induce emotions while being well controlled in terms of physical characteristics. In Experiment 1, photographs of emotional and neutral facial expressions were presented of the same actor to minimize physical differences. In Experiment 2, schematic emotional expressions were presented to further eliminate low-level differences. In Experiment 3, a probe-detection task was conducted to control for possible response-biases. Together, these data clearly demonstrate that emotional facial expressions predominate over neutral expressions; they are more often the first percept and they are perceived for longer durations. This is not caused by physical stimulus properties or by response-biases. This novel approach supports that emotionally significant visual stimuli are preferentially perceived.

A cross-cultural study of perceptual predominance in binocular rivalry.

Pairs of similar scenes, one Mexican and one from the United States, were presented stereoscopically to 12 Mexican Ss and 12 matched Ss from the United States. "Under these conditions of experimentally induced binocular rivalry,… scenes from the S's own culture tended to be perceptually predominant."

Aging and the depth of binocular rivalry suppression.

Two experiments were designed to examine the effect of aging on the strength of binocular rivalry suppression. To produce rivalry, orthogonally oriented sine-wave luminance gratings were presented dichoptically. The observers were then required either to discriminate the spatial location of a probe spot presented to the dominant or suppressed eye's view or to detect the presence or absence of the probe. The observers in the younger and older age groups exhibited typical rivalry suppression for both tasks (i.e., the probe was more difficult to detect or discriminate when presented to the suppressed eye), but the magnitude of the suppression was significantly larger in the older observers. This increased suppression that accompanies aging can be explained by a reduction in the inhibition produced by the binocular matching circuitry of S. R. Lehky and R. Blake's (1991) model.

The emotional blink: Adult age differences in visual attention to emotional information.

To assess age differences in attention-emotion interactions, the authors asked young adults (ages 18-33 years) and older adults (ages 60-80 years) to identify target words in a rapid serial visual presentation (RSVP) task. The second of two target words was neutral or emotional in content (positive in Experiment 1, negative in Experiment 2). In general, the ability to identify targets from a word stream declined with age. Age differences specific to the attentional blink were greatly reduced when baseline detection accuracy was equated between groups. With regard to emotion effects, older adults showed enhanced identification of both positive and negative words relative to neutral words, whereas young adults showed enhanced identification of positive words and reduced identification of negative words. Together these findings suggest that the nature of attention-emotion interactions changes with age, but there was little support for a motivational shift consistent with emotional regulation goals at an early stage of cognitive processing.

Rate of binocular rivalry alternation in psychotic and nonpsychotic patients.

To determine the relationship between binocular rivalry rate and the presence of psychopathology, rivalry rate measures for 2 1-min. observation periods were taken from 3 matched groups of organic, schizophrenic, and nonorganic-nonpsychotic patients. The rate of the nonorganic-nonpsychotic group increased significantly over observation periods relative to the other groups, a result consistent with other data which suggests that rate provides some measure of cognitive efficiency. Differences in rate between organic and schizophrenic groups were not found, contrary to previous report. Procedural variables which could account for the discrepancy are discussed.

Affective learning increases sensitivity to graded emotional faces.

How does the affective significance of emotional faces affect perceptual decisions? We manipulated affective significance by pairing 100% fearful faces with aversive electrical stimulation and hypothesized that increasing the significance of a stimulus via its prior history would lead to enhanced processing. After fear conditioning, participants viewed graded emotional faces that ranged from neutral to fearful. Faces were shown either in a color that was previously paired with shock or a color not paired with shock during conditioning. Increases in the frequency of "fearful" responses for faces shown in the shock-paired color were most robust for faces at intermediate intensity levels (40-60% fearful). Psychometric fits to the data revealed significant increased sensitivity for shock-paired relative to unpaired faces. Thus, despite identical physical features for shock-paired and unpaired stimuli (aside from the color, which was counterbalanced), more frequent (and faster) "fearful" responses were made when participants viewed affectively significant stimuli.

No aging bias favoring memory for positive material: Evidence from a heterogeneity-homogeneity list paradigm using emotionally toned words.

Some authors argue for a memory advantage of older adults for positively toned material. To investigate the contribution of selective processing to a positivity effect, the authors investigated young (n = 72, aged 18 to 31) and older (n = 72, aged 64 to 75) adults' memory for emotionally toned words using a multitrial paradigm that compares performance for heterogeneous (mixed valence) and homogeneous (single valence) lists. Regarding the age comparison, there was no evidence for an aging bias favoring positive material. Moreover, older adults' memory was less affected by emotion-based processing prioritization. Although there was no support for age-specific processing biases in memory for emotionally toned words, the findings are consistent with proposals that negative information receives processing priority in some contexts. Possible limits to the generalizability of the present findings (e.g., to nonverbal material) are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Memories of social interactions: Age differences in emotional intensity.

The current study examined age differences in the intensity of emotions experienced during social interactions. Because emotions are felt most intensely in situations central to motivational goals, age differences in emotional intensity may exist in social situations that meet the goals for one age group more than the other. Guided by theories of emotional intensity and socioemotional selectivity, it was hypothesized that social partner type would elicit different affective responses by age. Younger (n = 71) and older (n = 71) adults recalled experiences of positive and negative emotions with new friends, established friends, and family members from the prior week. Compared with younger adults, older adults reported lower intensity positive emotions with new friends, similarly intense positive emotions with established friends, and higher intensity positive emotions with family members. Older adults reported lower intensity negative emotions for all social partners than did younger adults, but this difference was most pronounced for interactions with new friends.

Divergent trajectories in the aging mind: Changes in working memory for affective versus visual information with age.

Working memory mediates the short-term maintenance of information. Virtually all empirical research on working memory involves investigations of working memory for verbal and visual information. Whereas aging is typically associated with a deficit in working memory for these types of information, recent findings suggestive of relatively well-preserved long-term memory for emotional information in older adults raise questions about working memory for emotional material. This study examined age differences in working memory for emotional versus visual information. Findings demonstrate that, despite an age-related deficit for the latter, working memory for emotion was unimpaired. Further, older adults exhibited superior performance on positive relative to negative emotion trials, whereas their younger counterparts exhibited the opposite pattern.

Effects of emotional valence and arousal upon memory trade-offs with aging.

Attention can be attracted faster by emotional relative to neutral information, and memory also can be strengthened for that emotional information. However, within visual scenes, often there is an advantage in memory for central emotional portions at the expense of memory for peripheral background information, called an emotion-induced memory trade-off. The authors examined how aging impacts the trade-off by manipulating valence (positive, negative) and arousal (low, high) of a central emotional item within a neutral background scene and testing memory for item and background components separately. They also assessed memory after 2 study–test delay intervals, to investigate age differences in the trade-off over time. Results revealed similar patterns of performance between groups after a short study–test delay, with both age groups showing robust memory trade-offs. After a longer delay, young and older adults showed enhanced memory for emotional items but at a cost to memory for background information only for young adults in negative arousing scenes. These results emphasize that attention and consolidation stage processes interact to shape how emotional memory is constructed in young and older adults.

"Selective Preference in Visual Fixation Away From Negative Images in Old Age? An Eye-Tracking Study": Correction.

Reports an error in the original article by D. M. Isaacowitz et al (Psychology and Aging, 2006[March], Vol 21[1], 40-48). Because of a printer's error, an incorrect version of Figure 2 appeared in the article. The correct version of the figure is provided. (The following abstract of this article originally appeared in record 2006-03906-005.) Recent studies have suggested that older individuals selectively forget negative information. However, findings on a positivity effect in the attention of older adults have been more mixed. In the current study, eye tracking was used to record visual fixation in nearly real-time to investigate whether older individuals show a positivity effect in their visual attention to emotional information. Young and old individuals (N = 64) viewed pairs of synthetic faces that included the same face in a nonemotional expression and in 1 of 4 emotional expressions (happiness, sadness, anger, or fear). Gaze patterns were recorded as individuals viewed the face pairs. Older adults showed an attentional preference toward happy faces and away from angry ones; the only preference shown by young adults was toward afraid faces. The age groups were not different in overall cognitive functioning, suggesting that these attentional differences are specific and motivated rather than due to general cognitive change with age.

Specifying emotional information: Regulation of emotional intensity via executive processes.

The degree of specificity at which emotional information is activated might determine evoked emotional intensity. However, the nature of this effect remains unclear. Four studies tested (a) whether people hold the na?ve theory that activating specific details of emotional information arouses acute feelings; (b) whether an emotionally distressed population (social phobics) also holds that theory; and (c) whether voluntarily focusing on specific aspects of a distressing situation reduces its emotional impact. Results indicate that control as well as emotionally distressed people hold a na?ve theory that specifying emotion increases its intensity. However, Studies 3 and 4 showed that voluntarily elaborating specific aspects of a distressing situation reduces distress. Results are discussed in terms of voluntary versus automatic processing of emotional information. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Intrasexual vigilance: The implicit cognition of romantic rivalry.

Four experiments tested the hypothesis that concerns about infidelity would lead people, particularly those displaying high chronic levels of romantic jealousy, to display a functionally coordinated set of implicit cognitive biases aimed at vigilantly processing attractive romantic rivals. Priming concerns about infidelity led people with high levels of chronic jealousy (but not those low in chronic jealousy) to attend vigilantly to physically attractive same-sex targets at an early stage of visual processing (Study 1), to strongly encode and remember attractive same-sex targets (Study 2), and to form implicit negative evaluations of attractive same-sex targets (Studies 3 and 4). In each case, effects were observed only for same-sex targets who were physically attractive—individuals who can pose especially potent threats to a person’s own romantic interests. These studies reveal a cascade of implicit, lower order cognitive processes underlying romantic rivalry and identify the individuals most likely to display those processes. At a broader conceptual level, this research illustrates the utility of integrating social cognitive and evolutionary approaches to psychological science.

Reported exposure and emotional reactivity to daily stressors: The roles of adult age and global perceived stress.

A central goal of daily stress research is to identify resilience and vulnerability factors associated with exposure and reactivity to daily stressors. The present study examined how age differences and global perceptions of stress relate to exposure and emotional reactivity to daily stressors. Sixty-seven younger (Mage = 20) and 116 older (Mage = 80) adults completed a daily stress diary and measures of positive and negative affect on 6 days over a 14-day period. Participants also completed a measure of global perceived stress. Results revealed that reported exposure to daily stressors is reduced in old age but that emotional reactivity to daily stressors did not differ between younger and older adults. Global perceived stress was associated with greater reported exposure to daily stressors in older adults and greater stress-related increases in negative affect in younger adults. Furthermore, across days on which daily stressors were reported, intraindividual variability in the number and severity of stressors reported was associated with increased negative affect, but only among younger adults.

Fuzzy picture processing: Effects of size reduction and blurring on emotional processing.

Previous studies have suggested that picture size reduction affects emotional reactions, possibly because scenes subtending a small visual angle are perceived as being more distant and less relevant compared to larger stimuli. However, pictures that subtend a small visual angle also contain few fine-grained details, which may determine less vivid representations and responses compared to larger and more detailed images. Critically, the present study compared two different types of manipulations, namely size reduction and low-pass spatial filtering, which determined similar detail loss but affected visual angles differently. Affective modulation was assessed using an evaluative task and a behavioral interference task. Results showed that the availability of fine-grained details, independently of visual angle, modulated emotional evaluation. Moreover, interference in an unrelated task was unaffected by either size reduction or low-pass spatial filtering. These findings suggest that high spatial frequencies affect subjective emotional response whereas attentional capture by affective stimuli seems to rely on information that is sufficient to allow a categorization of picture content.

Detection of emotional faces: Salient physical features guide effective visual search.

In this study, the authors investigated how salient visual features capture attention and facilitate detection of emotional facial expressions. In a visual search task, a target emotional face (happy, disgusted, fearful, angry, sad, or surprised) was presented in an array of neutral faces. Faster detection of happy and, to a lesser extent, surprised and disgusted faces was found both under upright and inverted display conditions. Inversion slowed down the detection of these faces less than that of others (fearful, angry, and sad). Accordingly, the detection advantage involves processing of featural rather than configural information. The facial features responsible for the detection advantage are located in the mouth rather than the eye region. Computationally modeled visual saliency predicted both attentional orienting and detection. Saliency was greatest for the faces (happy) and regions (mouth) that were fixated earlier and detected faster, and there was close correspondence between the onset of the modeled saliency peak and the time at which observers initially fixated the faces. The authors conclude that visual saliency of specific facial features--especially the smiling mouth--is responsible for facilitated initial orienting, which thus shortens detection.

Response bias in "remembering" emotional stimuli: A new perspective on age differences.

Older adults sometimes show a recall advantage for emotionally positive, rather than neutral or negative, stimuli (S. T. Charles, M. Mather, & L. L. Carstensen, 2003). In contrast, younger adults respond "old" and "remember" more often to negative materials in recognition tests. For younger adults, both effects are due to response bias changes rather than to enhanced memory accuracy (S. Dougal & C. M. Rotello, 2007). We presented older and younger adults with emotional and neutral stimuli in a remember-know paradigm. Signal-detection and model-based analyses showed that memory accuracy did not differ for the neutral, negative, and positive stimuli, and that "remember" responses did not reflect the use of recollection. However, both age groups showed large and significant response bias effects of emotion: Younger adults tended to say "old" and "remember" more often in response to negative words than to positive and neutral words, whereas older adults responded "old" and "remember" more often to both positive and negative words than to neutral stimuli.
