Repressive coping: Distraction using pleasant thoughts and memories.

To avoid exposure to unpleasant or unwanted emotional material, some people may distract themselves by summoning up pleasant thoughts such as happy memories. Manipulation of negative affect might therefore result in heightened accessibility of pleasant thoughts and memories, contrary to hypotheses of mood-congruent recall. In Experiment 1, repressors were faster to recall happy memories after watching an unpleasant film than after watching a neutral film. Nonrepressors showed the opposite effect (i.e., mood-congruent memory). In Experiment 2, after an unpleasant film, repressors were faster to recall a happy memory than to recall a sad memory. In Experiment 3, repressors spontaneously generated pleasant thoughts after watching an unpleasant film, whereas nonrepressors did not. Thus, repressors apparently cope with exposure to negative affective material by accessing pleasant thoughts. Results are discussed in terms of cognitive defenses against emotional distress and the associative structure of repression. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The 120-S minute: using analysis of work activity to prevent psychological distress among elementary school teachers

To avoid exposure to unpleasant or unwanted emotional material, some people may distract themselves by summoning up pleasant thoughts such as happy memories. Manipulation of negative affect might therefore result in heightened accessibility of pleasant thoughts and memories, contrary to hypotheses of mood-congruent recall. In Experiment 1, repressors were faster to recall happy memories after watching an unpleasant film than after watching a neutral film. Nonrepressors showed the opposite effect (i.e., mood-congruent memory). In Experiment 2, after an unpleasant film, repressors were faster to recall a happy memory than to recall a sad memory. In Experiment 3, repressors spontaneously generated pleasant thoughts after watching an unpleasant film, whereas nonrepressors did not. Thus, repressors apparently cope with exposure to negative affective material by accessing pleasant thoughts. Results are discussed in terms of cognitive defenses against emotional distress and the associative structure of repression.     

Differential effects of induced mood on retrieval of pleasant and unpleasant events from episodic memory.

Examined the effect of depressed mood on the accessibility of memories of past real-life experiences of a pleasant or unpleasant nature. By means of a mood induction procedure, 30 students (mean age 19.2 yrs) were made happy on one occasion and depressed on another. The 2 mood states differed significantly on self-report, speech-rate, and recall-latency measures. Stimulus words to which Ss had to associate past pleasant or unpleasant experiences were presented in each mood condition, and latency of retrieval was measured. Time to retrieve pleasant memories, relative to time to retrieve unpleasant memories, was significantly longer when Ss were depressed than when they were happy, suggesting a differential effect of mood on the accessibility of these 2 types of memory. Results are considered in relation to state-dependent learning and activation of memories, and their implications for models and treatment of depression are discussed. It is suggested that cognitive models of depression need to be extended to include a reciprocal relation between thought content and depressed mood.

Constraints on the effects of mood on memory.

In Study 1, pleasant and unpleasant personality trait words and abstract nouns were encoded in neutral mood and recalled in either induced depressed or induced happy mood, using 32 female and 32 male undergraduates assigned in equal numbers to 1 of the 4 conditions. Females recalled more pleasant than unpleasant words when in a happy mood and more unpleasant than pleasant words when in a depressed mood. Males failed to show this effect. Both sexes responded equally well to the induction procedures. There were no sex differences in pleasantness ratings of the words to be recalled. A prediction that differential effects of mood on recall would be greater for trait words than abstract nouns was not confirmed. In Study 2, everyday usage ratings by 36 Ss from Study 1 were obtained for the trait words from Study 1. Females gave higher usage ratings than males and, within the females, usage predicted the extent to which a word was preferentially recalled in a congruent mood state. Findings are discussed in relation to the associative network model of mood and memory, sex differences in depression, and cognitive vulnerability to depression.

Children's facial responsiveness to odors: Influences of hedonic valence of odor, gender, age, and social presence.

Facial responsiveness to pleasant and unpleasant odors was examined in 5- to 12 year-old children in either an alone condition (AC) or a social presence condition (SPC). The children failed to display reflex-like patterns, but they exhibited facial configurations that varied according to the odor valence and the social condition. Girls evidenced more smiles than did boys, but this sex difference was significant only in response to unpleasant odors in the SPC. Furthermore, untrained observers were able to accurately identify the children's facial responses to unpleasant odors in the AC only and to pleasant odors in the SPC only. These findings (a) suggest that facial responsiveness to odors is flexible and able to reorganize when display rules operate and (b) support the emotional and communicative functions of human facial behavior.

Effect of verbal cues on recognition memory and pleasantness evaluation of unfamiliar odors

The experiment investigated the effect of verbal cues on recognition memory for unfamiliar odors. 58 participants learned 20 odors of chemical substances. The control group learned the odors without accompanying verbal labels whereas two other groups learned the odors with accompanying verbal labels. The labels referred to relatively pleasant or unpleasant odor sources. On a memory test, administered 15 min. and also 1 wk. after the learning phase, participants were asked to recognize 10 learned odors from 10 unlearned odors and to evaluate each odor's pleasantness. Analysis showed (a) the verbal labels did not facilitate recognition of the unfamiliar odors, (b) recognition performance was lower after 1 wk. than after 15 min., and (c) rated pleasantness tended to be affected by the verbal label assigned to the odor in the learning phase.     

Mood and memory under natural conditions: Evidence for mood incongruent recall.

The effect of mood on memory was studied under natural conditions in 2 field quasi-experiments. In both, Ss in happy moods recalled autobiographical memories that were more negative than were memories recalled by subjects in bad moods, a phenomenon termed mood incongruent recall. Three subsequent laboratory experiments are reported that suggest that mood incongruent recall is a reliable phenomenon, occurring when subjects are unaware that their moods are relevant to the experiment. Mood incongruent recall is hypothesized to be related to mood regulation. The implications of these findings for the relation between mood and memory, for mood congruent recall, for laboratory mood inductions, and for self-regulation of mood and depression are discussed.

Effects of olfactory stimuli on urge reduction in smokers.

This study examined the possibility that exposure to olfactory stimuli can reduce self-reported urge to smoke. After an initial assessment of self-reported urge, nicotine-deprived smokers evaluated the pleasantness of a series of 8 odors. Facial expressions during odor presentations were coded with P. Ekman and W. V. Friesen's (1978) Facial Action Coding System. After odor administration, participants were exposed to smoking cues. Next, participants were administered their most pleasant, least pleasant, or a control odor (water) and reported their urge to smoke. Results indicated that sniffing either a pleasant or unpleasant odor reduced reported urge to smoke relative to the control odor. Reported pleasantness of the odors did not differentially affect urge reduction. Odors eliciting negative-affect-related expressions, however, were less effective than odors that did not elicit negative-affect-related expressions in reducing reported urge. Results of this preliminary investigation provide support for the consideration of odor stimuli as an approach to craving reduction. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Sequential unfolding of novelty and pleasantness appraisals of odors: Evidence from facial electromyography and autonomic reactions.

We investigated the effects of odors on appraisal processes and consequent emotional responses. The main goal was to test whether an odor is detected as novel or familiar before it is evaluated as pleasant or unpleasant. Participants performed a recognition task in which they were presented with pairs of unpleasant or pleasant odors (sample and target odors). Within a pair, the sample and target were either identical or different to assess participants’ novelty detection; unpleasant and pleasant target odors were contrasted to examine participants’ appraisal of intrinsic pleasantness. We measured facial expressions using electromyography and physiological reactions using electrocardiogram and electrodermal activity in response to odors. The earliest effects on facial muscles and heart rate occurred in response to novelty detection. Later effects on facial muscles and heart rate were related to pleasantness evaluation. This study is the first to demonstrate the existence of a sequence of appraisal checks for odors eliciting emotional reaction. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Repression and the inaccessibility of affective memories.

Examined 3 groups of Ss (repressors, low anxious, and high anxious) under 6 conditions of recall (general, happy, sad, anger, fear, and wonder). Ss were asked to recall personal experiences from childhood and to rate their current mood and the affective intensity of the memories. Repressors recalled significantly fewer negative memories than did low-anxious and high-anxious Ss and were substantially older at the time of the earliest negative memory recalled. Compared with low-anxious Ss, repressors also recalled fewer positive affective memories as well. This pattern of findings is consistent with the hypothesis that repression involves an inaccessibility to negative emotional memories and indicates further that repression is associated in some way with the suppression or inhibition of emotional experiences in general. The concept of repression as a process involving limited access to negative affective memories appears to be valid. (38 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Further evidence for mixed emotions.

Emotion theorists have long debated whether valence, which ranges from pleasant to unpleasant states, is an irreducible aspect of the experience of emotion or whether positivity and negativity are separable in experience. If valence is irreducible, it follows that people cannot feel happy and sad at the same time. Conversely, if positivity and negativity are separable, people may be able to experience such mixed emotions. The authors tested several alternative interpretations for prior evidence that happiness and sadness can co-occur in bittersweet situations (i.e., those containing both pleasant and unpleasant aspects). One possibility is that subjects who reported mixed emotions merely vacillated between happiness and sadness. The authors tested this hypothesis in Studies 1–3 by asking subjects to complete online continuous measures of happiness and sadness. Subjects reported more simultaneously mixed emotions during a bittersweet film clip than during a control clip. Another possibility is that subjects in earlier studies reported mixed emotions only because they were explicitly asked whether they felt happy and sad. The authors tested this hypothesis in Studies 4–6 with open-ended measures of emotion. Subjects were more likely to report mixed emotions after the bittersweet clip than the control clip. Both patterns occurred even when subjects were told that they were not expected to report mixed emotions (Studies 2 and 5) and among subjects who did not previously believe that people could simultaneously feel happy and sad (Studies 3 and 6). These results provide further evidence that positivity and negativity are separable in experience. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Personal nostalgia, world view, memory, and emotionality

Batcho's 1995 Nostalgia Inventory was completed by 210 respondents, 88 males and 122 females, ranging in age from 5 to 79 years old. Subjects scoring high on the Nostalgia Inventory rated the past more favorably than did subjects scoring low on the inventory but did not differ in ratings of the present or future. High-scoring individuals rated themselves more emotional, with stronger memories, need for achievement, and preference for activities with other people, but not as less happy, risk or thrill seeking, religious, logical, easily bored, or expecting to succeed. In a second study, 113 undergraduates, 32 men and 81 women, completed measures of nostalgia, memory, and personality. High-scoring subjects showed no advantage in free recall over low-scoring subjects but recalled more people-oriented autobiographical memories. Individuals scoring high on nostalgia were no more optimistic, pessimistic, or negatively emotional but scored higher on a measure of emotional intensity. Personal nostalgia was distinguished from social-historical nostalgia and world view. Results were discussed with respect to major theoretical approaches.     

Affect and Face Perception: Odors Modulate the Recognition Advantage of Happy Faces.

Previous choice reaction time studies have provided consistent evidence for faster recognition of positive (e.g., happy) than negative (e.g., disgusted) facial expressions. A predominance of positive emotions in normal contexts may partly explain this effect. The present study used pleasant and unpleasant odors to test whether emotional context affects the happy face advantage. Results from 2 experiments indicated that happiness was recognized faster than disgust in a pleasant context, but this advantage disappeared in an unpleasant context because of the slow recognition of happy faces. Odors may modulate the functioning of those emotion-related brain structures that participate in the formation of the perceptual representations of the facial expressions and in the generation of the conceptual knowledge associated with the signaled emotion.

Recall of pleasant and unpleasant words in depressed subjects.

In Exp I, 20 clinically depressed inpatients (mean age 39.9 yrs), 20 nondepressed inpatients (mean age 42.65 yrs), and 20 nonpatients (mean age 44 yrs) were shown a word list containing pleasant and unpleasant words. One-half of Ss in each group were given free-recall instructions, the other half were asked to rate each word on a pleasantness scale prior to recall. Results show that only depressed Ss given free-recall instructions recalled more unpleasant words than pleasant words. In Exp II, 30 clinically depressed inpatients (mean age 39.33 yrs) were shown a word list consisting of either (1) pleasant and unpleasant words, (2) unpleasant words, or (3) pleasant words. Results show that only Ss receiving the mixed list recalled more unpleasant than pleasant words. Findings support the hypothesis that depressed Ss selectively process unpleasant words and that this processing is at the expense of attention to pleasant words.

Olfaction and the "data" memory system in rats.

Conducted studies to characterize the memory system involved in successive olfactory discrimination learning in rats. Two odors emanated from different arms of a radical maze; 1 of the arms contained a water reward. After training on 4 to 5 pairs of odors Ss learned to discriminate the members of a new pair in 5–20 trials. Experiments in which either member of the pair was compared with a novel cue indicated that the Ss learn both positive and negative odors, rather than ignoring the negative cue. The memories for the odors were apparently persistent, and no evidence for retroactive interference from subsequent training was obtained. Animals trained on 3 component odors with 2 in common did not recognize the elements that were unshared when these were presented by themselves. Even when 1 of the 2 shared components was combined with the differentiating component into a cue the new cue was treated as a novel odor. Inclusion of a previously learned simple odor in a complex odor did affect the learning of that odor. Findings, combined with those of previous studies in which lesions were used, suggest that learning that a series of odor discriminations involves a version of the "data" memory system described by cognitive psychologists.

Affect, pain, and autobiographical memory.

Twenty-five young female undergraduates were tested on two occasions: once when they were experiencing menstrual pain of at least moderate severity and once when they were pain free. On each occasion, Ss rated their current levels of pain and affect and retrieved real-life events from their personal past. At the end of the second occasion, Ss were reminded of all of the events they had retrieved on either occasion, and then rated the pleasantness of these events at the time of their original occurrence. Results revealed that the impact of pain on autobiographical memory was wholly mediated by its influence on mood. That is, pain impeded access to memories of pleasant personal experiences, whereas it promoted the retrieval of unpleasant events only if pain was accompanied by an increase in unpleasant affect. Discussion centers on the clinical and cognitive implications of the present results, and on prospects for future research. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Semantic activation and episodic odor recognition in young and older adults.

Young, young–old, and old adults were examined in immediate and delayed episodic recognition of common odors. Items were presented in 3 different formats: name-only, odor-only, or odor-name. Ss made familiarity ratings for all items at study. In the delayed recognition test, Ss were asked to name the odors. Young Ss outperformed the 2 older age groups in both recognition tests, although the 2 older groups did not differ. Performance was higher in the odor-name condition than in the single-format conditions. Both familiarity and naming were related to recognition in all age groups. Most important, when naming was statistically controlled, age differences in odor recognition disappeared, suggesting that access to verbal labels largely determine age differences in recognition of common odors. Finally, the finding that recognition was enhanced in both young and older Ss in the odor-name condition suggests that odor memory may involve a similar degree of plasticity as other varieties of episodic memory.

Memories of yesterday’s emotions: Does the valence of experience affect the memory-experience gap?

Intense pain is often exaggerated in retrospective evaluations, indicating a possible divergence between experience and memory. However, little is known regarding how people retrospectively evaluate experiences with both pleasant and unpleasant aspects. The Day Reconstruction Method (DRM; Kahneman. Krueger, Schkade, Schwarz, & Stone, 2004b) provides a unique opportunity to examine memory-experience gaps in recollections of individual days, which elicit a wide gamut of emotions. We asked female participants (N = 810, Study 1, and N = 615, Study 2) to reconstruct episodes of the previous day using the DRM and demonstrated that memory and experience diverge for both pleasant and unpleasant emotions. When they rated their day overall in a retrospectively evaluative frame of mind, the participants recalled more unpleasant and pleasant emotions than they reported feeling during the individual episodes, with a larger gap for unpleasant emotions than for pleasant emotions. The findings suggest that separate processes are used for committing positive and negative events to memory and that, especially when unpleasant emotions are involved, prudence is favored over accuracy.
