Life is pleasant--and memory helps to keep it that way!

People's recollections of the past are often positively biased. This bias has 2 causes. The 1st cause lies in people's perceptions of events. The authors review the results of several studies and present several new comparative analyses of these studies, all of which indicate that people perceive events in their lives to more often be pleasant than unpleasant. A 2nd cause is the fading affect bias: The affect associated with unpleasant events fades faster than the affect associated with pleasant events. The authors review the results of several studies documenting this bias and present evidence indicating that dysphoria (mild depression) disrupts such bias. Taken together, this evidence suggests that autobiographical memory represents an important exception to the theoretical claim that bad is stronger than good.

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.     

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.

Characteristics associated with real and made-up events: The effects of event valence, event elaboration, and individual differences.

In three studies, participants rated both real and made-up personal events on several different characteristics. These included meta-cognitive beliefs about the perceived realness and typicality of these events, imagery ratings of visual detail, and emotional ratings of intensity and feelings. Studies 1 and 2 explored the impact of event valence (pleasant versus unpleasant) on these characteristics, whereas Study 3 focused on the effects of event elaboration involving guided imagery and journaling techniques. All three studies also included consideration of individual difference factors that might either enhance or attenuate the ratings that were obtained. Both Studies 1 and 2 found that pleasant events (be they real or made-up), were viewed as more typical, and more likely to have happened and be true, than unpleasant events. This pattern of meta-cognitive judgments provided support for a general positivity hypothesis, which proposes that most individuals orient towards and emphasize pleasant rather than unpleasant life experience and events. In contrast, the imagery-related components of these events, such as visual details, location, and time, were much less sensitive to the manipulation of event valence. Strong imagery-related effects, however, were noted when events were elaborated in the final study. Furthermore, this event elaboration manipulation also resulted in heightened meta-cognitive judgments of typicality, likelihood of the event having happened, and of being true. Finally, across all three studies, a series of correlational analyses indicated that the individual difference factors did not have any systematic effect on any of the event characteristic ratings. However, when event valence was not specifically manipulated (in Study 3), depressed individuals spontaneously provided twice as many unpleasant personal events as nondepressed individuals. These findings were then discussed in terms of source-confusion issues regarding personal memory accuracy, as well as the further extension of a recent model of autobiographical memory to incorporate event properties such as valence and elaboration.

Self-Monitoring, Activity Levels, and Mood in the Development and Maintenance of Depression.

The reactive effect on mood of self-monitoring pleasant and unpleasant events was assessed. Forty-five females spent 28 days monitoring in one of four conditions: (a) pleasant events, (b) unpleasant events, (c) both, and (d) no monitoring. Motor activity level (pedometer recordings) and mood were also assessed daily. Class of event monitored was not found to influence mood. Correlations between mood and both pleasant and unpleasant events were found even with activity level partialed out. Implications for self-monitoring assessment in depression therapy programs and for models of depression are discussed. (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)     

Some relations between pleasant and unpleasant mood-related events and depression.

Studied (a) the validity of 2 methods of identifying reinforcing and punishing events, (b) their interrelations and dimensional structure, and (c) their relation to depression. A total of 909 Ss who were screened with the MMPI and classified as depressed, nondepressed psychiatric, or normal control rated the frequency and the subjective enjoyability or aversiveness of 320 pleasant (the Pleasant Event Schedule Form III) and 320 unpleasant events (the Unpleasant Events Schedule Form I). Some Ss also monitored the occurrence of pleasant and unpleasant events and rated their mood on a daily basis (Depression Adjective Check List). Correlations between each event and mood were calculated and used to identify 49 pleasant and 35 unpleasant "mood-related events." The proportion of Ss for whom the events correlated with mood and the mean enjoyability and aversiveness of the items were hypothesized to be measures of reinforcing or punishing impact. As predicted, statistically significant correlations between these 2 measures were obtained. The mood-related events also discriminated more strongly between depressed and nondepressed groups than the non-mood-related events did. The intercorrelations between pleasant and unpleasant events yielded separate and orthogonal dimensions of punishment and of reinforcement.

Mood, pleasant events, and unpleasant events: Two pilot studies.

Assessed the relationship between mood and both pleasant and unpleasant events in 2 studies with a total of 34 undergraduates. Ss made self-ratings of mood and kept daily logs of pleasant and unpleasant events for approximately 2 wks. Intrasubject correlations in both studies suggested that mood was related to pleasant and unpleasant events independently. Intersubject correlations were consistent but nonsignificant. Cross-lagged correlations were significantly less than same-day correlations. Weighted event scores produced marginally higher correlations with mood than unweighted scores. Minor sex differences are noted. Implications of these results for theory and practice are discussed. (17 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Mood dependent memory for events of the personal past.

Previous research on mood dependent memory (MDM) suggests that the more one must rely on internal resources, rather than on external aids, to generate both the target events and the cues required for their retrieval, the more likely is one's memory for these events to be mood dependent. To instantiate this "do-it-yourself" principle, 3 experiments were conducted in which Ss experiencing either a pleasant or an unpleasant mood generated autobiographical events in response to neutral nouns. Subsequently, Ss were tested for event free recall while in the same or the alternative mood state. All 3 studies showed MDM, such that the likelihood of recalling an event generated 2 or 3 days ago was higher when generation and recall moods matched than when they mismatched. Prospects for future research aimed at elucidating and extending these results are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Predispositions to approach and avoid are contextually sensitive and goal dependent.

The authors show that predispositions to approach and avoid do not consist simply of specific motor patterns but are more abstract functions that produce a desired environmental effect. It has been claimed that evaluating a visual stimulus as positive or negative evokes a specific motor response, extending the arm to negative stimuli, and contracting to positive stimuli. The authors showed that a large congruency effect (participants were faster to approach pleasant and avoid unpleasant stimuli, than to approach unpleasant and avoid pleasant stimuli) could be produced on a novel touchscreen paradigm (Experiment 1), and that the congruency effect could be reversed by spatial (Experiment 2) and nonspatial (Experiment 3) response effects. Thus, involuntary approach and avoid response activations are not fixed, but sensitive to context, and are specifically based on the desired goal.

On the Subjective Quality of Social Justice: The Role of Affect as Information in the Psychology of Justice Judgments.

This article argues that it is not uncommon for people forming justice judgments to lack information that is most relevant in the particular situation. In information-uncertain conditions, people may therefore construct justice judgments by relying on how they feel about the events they have encountered, and justice judgments may hence be strongly influenced by affect information. Findings show that in information-uncertain conditions, the affective states that people had been in prior and unrelated to the justice event indeed strongly influenced their justice judgments. These findings thus reveal that in situations of information uncertainty, people's judgments of justice can be very subjective, susceptible to affective states that have no logical relationship with the justice judgments they are constructing. Implications for the social psychology of justice and the literature on social cognition and affect are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Emotional reactivity to daily events in major and minor depression.

Although emotional dysfunction is an important aspect of major depressive disorder (MDD), it has rarely been studied in daily life. Peeters, Nicolson, Berkhof, Delespaul, and deVries (2003) observed a surprising mood-brightening effect when individuals with MDD reported greater reactivity to positive events. To better understand this phenomenon, we conducted a multimethod assessment of emotional reactivity to daily life events, obtaining detailed reports of appraisals and event characteristics using the experience-sampling method and the Day Reconstruction Method (Kahneman, Krueger, Schkade, Schwarz, & Stone, 2004) in 35 individuals currently experiencing a major depressive episode, 26 in a minor depressive (mD) episode, and 38 never-depressed healthy controls. Relative to healthy controls, both mood-disordered groups reported greater daily negative affect and lower positive affect and reported events as less pleasant, more unpleasant, and more stressful. Importantly, MDD and mD individuals reported greater reductions in negative affect following positive events, an effect that converged across assessment methods and was not explained by differences in prevailing affect, event appraisals, or medications. Implications of this curious mood-brightening effect are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Affect and memory: Effects of pleasant and unpleasant odors on retrieval of happy and unhappy memories.

Interpretation of studies of induced mood and memory is complicated by the fact that mood induction procedures may elicit mood-related cognition in addition to mood per se. We used odors to produce positive and negative experiences with minimal cognitive involvement. College women recalled memories cued by neutral words while exposed to a pleasant odor, unpleasant odor, or no odor. Subjects then rated their memories as to how happy or unhappy the events recalled were at the time they occurred. Subjects in the pleasant odor condition produced a significantly greater percentage of happy memories than did subjects in the unpleasant odor condition. When subjects who did not find the odors at least moderately pleasant or unpleasant were removed from the analysis, more pronounced effects on memory were found. The results suggest that congruence between the general hedonic tone of current experience and that of material in long-term memory is sufficient to bias retrieval.

Film music influences how viewers relate to movie characters.

Film music has powerful aesthetic effects on the perception and understanding of screen content, but does it also influence viewers' sense of connection with movie characters thereby creating antecedents for an experience of empathy? Participants viewed clips showing characters' neutral or ambiguous reaction to an event, person, or object. Viewers rated character likability and their certainty about characters' thoughts in three conditions: thriller music, melodrama music, and no music. The effect of music conditions differed significantly from the no music condition. Compared to melodramatic music, thriller music significantly lowered likability and certainty about characters' thoughts. During subsequent cued recall of screen content, thriller music increased anger attributions and lowered sadness attributions, while melodramatic music increased love attributions and lowered fear attributions. The study provides evidence that film music can influence character likability and the certainty of knowing the character's thoughts, which are antecedents of empathetic concern and emphatic accuracy. Thus film music may be regarded as modulating antecedents of empathic concern and empathic accuracy. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Common and distinct patterns of affective response in dimensions of anxiety and depression.

The authors examined the time course of affective responding associated with different affective dimensions--anxious apprehension, anxious arousal, and anhedonic depression--using an emotion-modulated startle paradigm. Participants high on 1 of these 3 dimensions and nonsymptomatic control participants viewed a series of affective pictures with acoustic startle probes presented before, during, and after the stimuli. All groups exhibited startle potentiation during unpleasant pictures and in anticipation of both pleasant and unpleasant pictures. Compared with control participants, symptomatic participants exhibited sustained potentiation following the offset of unpleasant stimuli and a lack of blink attenuation during and following pleasant stimuli. Common and unique patterns of affective responses in the 3 types of mood symptoms are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Does anhedonia in schizophrenia reflect faulty memory for subjectively experienced emotions?

The authors evaluated whether self-reported trait anhedonia in schizophrenia reflects faulty memory, such that patients are capable of experiencing pleasure while engaged in enjoyable activities but underestimate their pleasure in recalling these experiences. Thirty schizophrenia patients and 31 nonpatient control participants rated their emotional responses to pleasant and neutral foods and film clips and completed a surprise recall task for their emotions after a 4-hr delay. Despite reporting elevated trait anhedonia, patients did not significantly differ from control participants in immediate pleasant emotional responses to the stimuli or in delayed recall for these experiences. In-the-moment pleasure and short-term retention for emotional experiences thus appear to be relatively intact in schizophrenia. Alternative explanations for the hedonic deficit in this disorder are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Desensitization to media violence: Links with habitual media violence exposure, aggressive cognitions, and aggressive behavior.

This study examined the links between desensitization to violent media stimuli and habitual media violence exposure as a predictor and aggressive cognitions and behavior as outcome variables. Two weeks after completing measures of habitual media violence exposure, trait aggression, trait arousability, and normative beliefs about aggression, undergraduates (N = 303) saw a violent film clip and a sad or a funny comparison clip. Skin conductance level (SCL) was measured continuously, and ratings of anxious and pleasant arousal were obtained after each clip. Following the clips, participants completed a lexical decision task to measure accessibility of aggressive cognitions and a competitive reaction time task to measure aggressive behavior. Habitual media violence exposure correlated negatively with SCL during violent clips and positively with pleasant arousal, response times for aggressive words, and trait aggression, but it was unrelated to anxious arousal and aggressive responding during the reaction time task. In path analyses controlling for trait aggression, normative beliefs, and trait arousability, habitual media violence exposure predicted faster accessibility of aggressive cognitions, partly mediated by higher pleasant arousal. Unprovoked aggression during the reaction time task was predicted by lower anxious arousal. Neither habitual media violence usage nor anxious or pleasant arousal predicted provoked aggression during the laboratory task, and SCL was unrelated to aggressive cognitions and behavior. No relations were found between habitual media violence viewing and arousal in response to the sad and funny film clips, and arousal in response to the sad and funny clips did not predict aggressive cognitions or aggressive behavior on the laboratory task. This suggests that the observed desensitization effects are specific to violent content. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Pleasant events, unpleasant events, and depression.

A review of previous research on P. M. Lewinsohn's (1974) model of depression shows that the causal link between a lack of response-contingent positive reinforcement and subsequent depression remains unsubstantiated. The present study tested this causal relationship through the use of cross-lagged panel correlation. 197 undergraduates completed a battery of measures of depression and pleasant events (including the Beck Depression Inventory and the Pleasant Events Schedule, respectively) twice, 1 mo apart. Results reveal that the null hypothesis of spuriousness could not be rejected, suggesting that the relation often found between a lack of pleasant events and depression is probably due to some unmeasured 3rd variable. Results also indicate that there was no causal relation between unpleasant events and depression. Possible 3rd-variable explanations are discussed.

Pleasantness-unpleasantness of environmental sounds and gender difference in evaluation

The present experiment examined emotional evaluation of 40 environmental sounds which were presented to 388 college students in a lecture room. Students were required to rate pleasantness-unpleasantness, to identify the sounds, and to rate their confidence about their identifications. Analysis showed that the pleasant sounds were natural and musical sounds and that the unpleasant sounds were sounds of a belch, of a dentist's drill, and of scratching on a blackboard. It is interesting that for pleasant sounds confidence was always high, which suggested that emotional evaluation of the environmental sounds was closely related to the confidence of observers in their identifications of the sounds. Gender differences were noted on the ratings on pleasantness-unpleasantness of environmental sounds, that is, women evaluated the pleasant sounds as more pleasant than men, and men evaluated the unpleasant sounds as not so unpleasant as did women.
