Effects of preexisting moods on observers' reactions to helpful and nonhelpful models

Two experiments investigated the effects of preexisting mood on observers' reactions to helpful and nonhelpful models. The major predictions, derived from a social learning analysis of altruism and Isen's “cognitive loop” hypothesis, where that (1) subjects experiencing positive moods would be prosocially inclined if exposed to a helpful but not a nonhelpful model, and (2) subjects experiencing negative moods would accede to a request for assistance regardless of the type of model they had observed. Introductory psychology students underwent a positive, negative, or (in Experiment 1) a neutral mood induction. They then observed a model respond either positively or negatively to another person's request for assistance, and were subsequently provided an opportunity to assist the help-seeker. The results were highly consistent across the two experiments. The model's behavior had a stronger impact on subjects' help giving than did preexisting moods. However, internal analyses revealed that the intensity of moods that subjects were experiencing affected their reactions to modeling cues. The prosocial behavior of good mood subjects was positively correlated with the positivity of their moods if they had witnessed a helpful but not a nonhelpful model. By contrast, the helpfulness of subjects experiencing negative moods was positively correlated with the negativity of those moods, regardless of the type of model subjects had observed. The implications of these outcomes for the social learning analysis of altruism and the “cognitive loop” hypothesis are discussed.     

Is manipulation of mood a critical component of cognitive bias modification procedures?

This paper investigates whether changes in mood state are an important component of cognitive bias modification (CBM) procedures. In a novel CBM procedure participants read either positive or negative statements relating to social issues for 5 min. Interpretation bias was measured by means of a scrambled sentence test, which was presented both before and after the CBM procedure. Participants who read the positive statements made more positive resolutions to the scrambled sentences, while participants who read the negative statements made more negative resolutions. Thus, the appropriate positive and negative interpretative biases were induced by the CBM procedure. However, significant mood changes also occurred following CBM. In Experiment 2, a musical mood induction procedure was presented with depressing or elating music. As before, a scrambled sentence test was presented both before and after the musical mood induction. Mood changed in accordance with the valence of the music to the same extent as with CBM. Critically however, performance on the scrambled sentence task did not change for both groups. This demonstrates that a change in mood state is not sufficient for a change in cognitive bias to occur.     

Factors related to perceived helpfulness in supporting highly distressed individuals through an online support chat.

The purpose of the study was to examine the contribution made by dimensions of session-impact factors (depth and smoothness), end-of-session factors of client's mood (positivity and emotional arousal), and several textual variables (use of positive and negative emotional words; helper's and client's writing lengths) to perceived helpfulness of emotional support conversations carried on by trained, paraprofessional helpers through an Internet chat with highly distressed individuals. Two studies were conducted at an Israeli, exclusively online emotional support service for suicidal and highly distressed people who have undergone various negative experiences (SAHAR). Study 1 compared 40 chat conversations deliberately indicated by clients as having been helpful at the termination stage of session with 40 other conversations, using expert judgments of session-impact factors, as well as objective word counts for textual variables. Study 2 examined correlations between helpers' evaluation of the sessions' helpfulness to clients in 60 (other) chat support conversations and session-impact factors and textual variables. The findings of Study 1 showed that all four impact factors significantly differentiated between helpful and other conversations, while textual variables did not. In Study 2, the results showed that all four session-impact factors positively correlated with session helpfulness, yielding multiple R = 0.54, as well as the length of helper's and client's writing. The implications of these studies are similar to offline counseling sessions: deep, smooth conversations that yield positive responses and arouse clients' emotions in online support are more helpful than shallow, bumping conversations that leave clients emotionally indifferent. Longer writing, by both helpers and clients, seems to be an important factor, as well.     

Emotional states and memory biases: effects of cognitive priming and mood

Recent studies have shown that naturally occurring and experimentally induced affect states enhance the accessibility to retrieval of memories of life experiences that are congruent in valence with the affect state. Previous studies have suggested that this memory bias results from the influence of affective processes on memory retrieval. In our study we manipulated mood state by having subjects read statements expressing positive or negative self-evaluative ideas or describing somatic states that often accompany positive or negative mood states. The somatic and self-evaluative statements had, in general, equally strong effects on mood state. In spite of this, however, the self-evaluative statements had a stronger impact on recall latencies for life experiences than did the somatic statements. Moreover, the impact of the self-evaluative, but not the somatic, statements on recall was found to be independent of the statements' effects on mood state. This suggests that the cognitions accompanying a mood-altering experience may have a substantial effect on the capacity of the mood state to influence memory retrieval.     

Self-referencing, quality of argument, and persuasion

This research examines whether self-referencing and self-attention facilitate careful examination of a message, referred to as systematic processing. In Experiment 1, undergraduates (n=158) who were induced to be either high or low in self-referencing read either a strong or a weak two-sided article that discussed tuition increases. Contrary to predictions, low self-referencing participants agreed more with increasing tuition than high self-referencing participants. Participants who read strong versus weak arguments agreed more with increasing tuition. In Experiment 2 undergraduates (n=204) who were either high or low in self-attention and either high or low in self-referencing read either a strong or weak two-sided article that discussed tuition increases. Consistent with predictions, participants who were either high in self-attention or high in self-referencing were more persuaded by strong than weak arguments. Specifically, both high self-attention, low self-referencing participants and low self-attention, high self-referencing participants were significantly more persuaded by strong than weak arguments. There was a trend for high self-attention, high self-referencing participants to be more persuaded by strong than weak arguments. There were no argument quality effects for low self-attention low self-referencing participants. The results of these two studies suggest that both self-referencing and self-attention facilitate systematic processing.     

Emotional processing of individuals high in psychopathic traits

One of the most important clinical features of psychopaths is their differential emotional response style. The present study examined the modulating effect of negative mood induction on the processing of emotional information and its relation to psychopathy. The sample of 105 participants were randomly assigned to two types of mood induction conditions (negative vs neutral) and viewed three types of visual stimuli (positive, neutral, negative). Psychopathic Personality Inventory‐R (PPI‐R; Lilienfeld & Andrews) was employed to measure their psychopathic traits. It was hypothesized that individuals high on PPI‐II (i.e., self‐centered impulsivity) would show greater response latencies to emotionally negative pictures when they were induced into a negative mood compared to individuals high on PPI‐I (i.e., fearless dominance). In general, individuals high on PPI‐II showed greater response latencies to emotionally negative pictures, but their responsivity did not vary as a function of mood manipulation or task demands. When controlling the influence of other PPI factors, PPI‐I predicted reaction time (RT) facilitation to positive pictures in general (i.e., faster RT), and when interacting with a negative mood induction, it predicted longer viewing time of and more difficulty disattending from positive pictures (i.e., slower RT). These results were discussed within emotional processing theory associated with psychopathy.     

Are you being served…? An unobtrusive experiment of affective influences on helping in a department store

Based on recent theories of affect and cognition, this unobtrusive field experiment predicted and found that induced positive mood improved real‐life customer service behaviors by less experienced sales staff, but had no effect on the behaviors of experienced long‐term staff in several department stores. Positive or negative mood was unobtrusively induced in sales staff in major department stores by a confederate. A second confederate, blind to the mood induction, then asked employees for help to locate a non‐existent item. The frequency and duration of helpful behaviors in response to the request was recorded. Consistent with Forgas' Affect Infusion Model (AIM), less experienced employees showed a significant mood‐congruent pattern in their responses helping more in a positive than in a negative mood. Long‐term employees who could rely on routine, direct access processing were not influenced by the mood induction. The implications of these findings for contemporary affect‐cognition theorizing and for everyday affective influences on interpersonal behaviors and customer service delivery are considered.

The effect of self-distancing on adaptive versus maladaptive self-reflection in children

Although children and adolescents vary in their chronic tendencies to adaptively versus maladaptively reflect over negative feelings, the psychological mechanisms underlying these different types of self-reflection among youngsters are unknown. We addressed this issue in the present research by examining the role that self-distancing plays in distinguishing adaptive versus maladaptive self-reflection among an ethnically and socioeconomically diverse sample of fifth-grade public schoolchildren. Children were randomly assigned to analyze their feelings surrounding a recent anger-related interpersonal experience from either a self-immersed or self-distanced perspective. They then rated their negative affect and described in writing the stream of thoughts they experienced when they analyzed their feelings. Children's stream-of-thought essays were content analyzed for the presence of recounting statements, reconstruing statements, and blame attributions. Path analyses indicated that children who analyzed their feelings from a self-distanced perspective focused significantly less on recounting the "hot," emotionally arousing features of their memory (i.e., what happened to me?) and relatively more on reconstruing their experience. This shift in thought content--less recounting and more reconstruing--led children in the self-distanced group to blame the other person involved in their recalled experience significantly less, which in turn led them to display significantly lower levels of emotional reactivity. These findings help delineate the psychological mechanisms that distinguish adaptive versus maladaptive forms of self-reflection over anger experiences in children. Their basic findings and clinical implications are discussed.     

Mood as a resource in dealing with health recommendations: How mood affects information processing and acceptance of quit-smoking messages

Objective: An experimental study tested the effects of positive and negative mood on the processing and acceptance of health recommendations about smoking in an online experiment. It was hypothesised that positive mood would provide smokers with the resources to systematically process self-relevant health recommendations.

Design: One hundred and twenty-seven participants (smokers and non-smokers) read a message in which a quit smoking programme was recommended. Participants were randomly assigned to one of four conditions: positive versus negative mood, and strong versus weak arguments for the recommended action.

Main outcome measures: Systematic message processing was inferred when participants were able to distinguish between high- and low-quality arguments, and by congruence between attitudes and behavioural intentions. Persuasion was measured by participant's attitudes towards smoking and the recommended action, and by their intentions to follow the action recommendation.

Results: As predicted, smokers systematically processed the health message only under positive mood conditions; non-smokers systematically processed the health message only under negative mood conditions. Moreover, smokers’ attitudes towards the health message predicted intentions to quit smoking only under positive mood conditions.

Conclusion: Findings suggest that positive mood may decrease defensive processing of self-relevant health information.     

How affective states, task difficulty, and self-concepts influence the formation and consequences of performance expectancies

Positive versus negative affective states are associated with the use of broad versus specific knowledge structures. We predicted that specific self-concepts and task difficulty would affect performance expectancies only for individuals in a negative mood; for individuals in a positive mood, only the general self-concept, but not task difficulty, would affect performance expectancies. In an experiment, we manipulated task difficulty and mood, and we assessed self-concepts, performance expectancies, and task performance. The expected interactions for the formation of performance expectancies (mood × general self-concept, mood × specific self-concept, mood × difficulty) were found. Concerning the consequences of performance expectancies, we predicted that expectancies would affect actual performance only if the task was difficult and if task difficulty was taken into account when the expectancy is generated. This hypothesis was supported: The relationship between performance expectancies and actual performance was significant only for difficult tasks and given negative mood.     

Distinct parietal sites mediate the influences of mood,arousal, and their interaction on human recognition memory

The two dimensions of emotion, mood valence and arousal, have independent effects on recognition memory. At present, however, it is not clear how those effects are reflected in the human brain. Previous research in this area has generally dealt with memory for emotionally valenced or arousing stimuli, but the manner in which interacting mood and arousal states modulate responses in memory substrates remains poorly understood. We investigated memory for emotionally neutral items while independently manipulating mood valence and arousal state by means of music exposure. Four emotional conditions were created: positive mood/high arousal, positive mood/low arousal, negative mood/high arousal, and negative mood/low arousal. We observed distinct effects of mood valence and arousal in parietal substrates of recognition memory. Positive mood increased activity in ventral posterior parietal cortex (PPC) and orbitofrontal cortex, whereas arousal condition modulated activity in dorsal PPC and the posterior cingulate. An interaction between valence and arousal was observed in left ventral PPC, notably in a parietal area distinct from the those identified for the main effects, with a stronger effect of mood on recognition memory responses here under conditions of relative high versus low arousal. We interpreted the PPC activations in terms of the attention-to-memory hypothesis: Increased arousal may lead to increased top-down control of memory, and hence dorsal PPC activation, whereas positive mood valence may result in increased activity in ventral PPC regions associated with bottom-up attention to memory. These findings indicate that distinct parietal sites mediate the influences of mood, arousal, and their interplay during recognition memory.     

Valence and Arousal Ratings for Velten Mood Induction Statements

Participants rated 84 statements adapted from Velten's original mood induction statements—designed to induce positive and negative mood—on two dimensions of emotion (valence and arousal), using the Self Assessment Manikin (SAM) (P. J. Lang, M. M. Bradley, & B. N. Cuthbert, 1999). Fifty-two of these Velten positive, negative, and neutral statements yielded SAM valence ratings that were consistent with Velten's previous valence designation (E. Velten, 1968). Reliability analyses for the positive, negative, and neutral statements indicated a high level of internal consistency in the three statement groups. Arousal and valence ratings of the statements were positively correlated. Related issues concerning differences in rating verbal versus visual emotional stimuli and recommendations for future work to improve the validity of Velten's mood induction statements are addressed.     

Experimental induction of emotional conditions--alternatives to the Velten method]

The technique most often used to induce emotion is based on self-referent statements read by the subjects (Velten, 1968). This technique is known to be of intermediate efficiency. Therefore film and hypnosis-like procedures were investigated as alternative techniques. Efficiency was tested using two selected scales of a mood questionnaire (SES by Hampel, 1977). The subjects were male and female students. Both alternative procedures allowed us to induce significant changes in Ss' moods. The film method was more efficient than the Velten-technique in inducing a negative mood, whereas it was equally efficient in inducing a positive mood. The hypnosis-like procedure, however, was not more efficient than the Velten-technique. Obviously film is a quite efficient and easy applicable alternative technique to induce moods.     

Upsetting social interactions and distress among Alzheimer's disease family care-givers: A replication and extension

Although several studies have suggested that negative aspects of relationships have a greater impact on mood than positive elements, the individuals in these studies have been victims of life crises. To assess the generality of these findings, social support and mood data were collected from two well-matched groups that differed with respect to the presence of a chronic stressor in their lives. The 34 family care-givers for Alzheimer's disease victims and 34 comparison persons (non-care-givers) did not differ in the frequency of contacts, the closeness of their relationships, or ratings of the helpfulness or upset associated with the relationships. However, while upset accounted for a significant portion of the variance in care-givers' depressive symptoms in regression equations, neither upset nor helpfulness was significantly related to mood in non-care-givers. Care-givers whose relatives had more symptomatic Alzheimer's disease behaviors were more distressed and described their relationships with others as more upsetting. Implications for interventions and for the contextual importance of upsetting or negative support are discussed.     

Can happy mood reduce the just world bias? Affective influences on blaming the victim

Do temporary moods influence people's tendency to blame victims for undeserved negative events? Based on research on the just world effect and recent affect theories, this experiment predicted and found that positive mood decreased and negative mood increased people's motivation to blame innocent victims for their misadventures. Participants (N = 70) were induced into positive or negative mood by viewing films, and subsequently read a newspaper article describing a random assault on either a fellow student (in-group member) or a corporate employee (out-group member). Their reactions were assessed on three measures: attributions of responsibility, dissociation from the victim and character evaluations. Positive mood reduced and negative mood increased the tendency to blame the victim, and in-group victims were blamed more than out-group victims. These results are discussed in terms of recent theories of affect and motivation, and their implications for real-life social judgments are considered.     

Sadness and ruminative thinking independently depress people's moods

Depression and rumination often co‐occur in clinical populations, but it is not clear which causes which, or if both are manifestations of an underlying pathology. Does rumination simply exacerbate whatever affect a person is experiencing, or is it a negative experience in and of itself? In two experiments we answer this question by independently manipulating emotion and rumination. Participants were allocated to sad or neutral (in Experiment 1), or sad, neutral or happy (Experiment 2) mood conditions, via a combination of emotionally evocative music and autobiographical recall. Afterwards, in both studies, participants either ruminated by thinking about self‐relevant statements or, in a control group, thought about self‐irrelevant statements. Taken together, our data show that, independent of participants' mood, ruminators reported more negative affect relative to controls. The findings are consistent with theories suggesting that self‐focus is itself unpleasant, and illustrate that depressive rumination comprises both affective and ruminative components, which could be targeted independently in clinical samples.     

Manic thinking: independent effects of thought speed and thought content on mood

This experiment found that the speed of thought affects mood. Thought speed was manipulated via participants' paced reading of statements designed to induce either an elated or a depressed mood. Participants not only experienced more positive mood in response to elation than in response to depression statements, but also experienced an independent increase in positive mood when they had been thinking fast rather than slow--for both elation and depression statements. This effect of thought speed extended beyond mood to other experiences often associated with mania (i.e., feelings of power, feelings of creativity, a heightened sense of energy, and inflated self-esteem or grandiosity).     

Stroke patients' well-being as a function of caregiving spouses' helpful and unhelpful actions

This study examined the perceptions that 55 older married stroke patients had about themselves and about the motivations of their caregiving spouses when they judged their spouses' actions to be helpful and when they judged them to be unhelpful. It also examined how these perceptions were related to patients' well-being (depression, positive affect, marital satisfaction). Patients had more negative perceptions of themselves and of their spouses when they judged the actions to be unhelpful than when they judged them to be helpful. The hypothesis that perceptions about unhelpful actions would be more strongly related to patients' well-being than would perceptions about helpful actions was only partially supported. Perceptions about unhelpful actions were related to patients' depression, but perceptions about helpful actions were related to positive affect. Both kinds of perceptions were related to marital satisfaction. Findings begin to explicate the complex relationship between perceived helpfulness of actions and well-being.     

College Men’s Concerns About Sharing Dormitory Space with a Male-to-Female Transsexual

We examined male college students’ attitudes toward sharing dormitory space with a male-to-female (MTF) transsexual. Participants read three scenarios, in a sequence of either increasing or decreasing contact with the transsexual, in which they imagined sharing dormitory space with a MTF transsexual as a roommate, in the bathroom, and at a residence hall meeting, after each of which they answered open-ended questions about how they would feel or act, or what they would do if they were a resident advisor, in the imagined scenarios. Participants then rated statements measuring their attitudes toward transsexuals and toward masculine norms. Whether they imagined increased or decreased contact, participants expressed comparable transphobia, and made numerous negative and neutral statements and fewer positive statements about how they would feel or act. However, many students made positive statements about how they would act toward the transsexual, particularly in the roommate situation. Adherence to masculine norms and transphobia were so highly positively correlated that they apparently measured a common attitude, but regression analyses indicated that transphobia mediated the association between adherence to masculine norms and frequencies of positive, negative and neutral responses to the open-ended questions. Men who were Christian, from middle to high SES families, and heterosexual were more transphobic and adhered more to masculine norms than those who were nonChristian, from lower SES families, and gay, respectively. Black and white men were equally transphobic and adhered equally to masculine norms. The men’s recommendations when imagining themselves as a resident advisor typically concerned making connections between the men and the transsexual and controlling the situation.     

Cortical alpha rhythm, biofeedback, and the determinants of subjective state

A critical assumption in the rationale for the clinical application of voluntary control over central nervous system (CNS) activity is that there exists a direct relationship between specific CNS activities and specific subjective mood states. The experiment reported here was based on the idea that a joint manipulation of both cognitive and physiological (i.e., alpha electroencephalographic [EEG]) variables would provide information required for an explication of the processes involved in subjective mood change. Three main variables were considered in the present experiment. First, the instructions were designed to induce a "set" or expectations for either positive or negative changes in subjective mood. Second, the type of feedback (alpha or not alpha) was varied. Those in the not-alpha feedback condition received feedback contingent on the absence of alpha activity, whereas those in the alpha feedback condition received feedback contingent on the presence of alpha activity. Third, an estimate of each individual's baseline alpha density was obtained, and on this basis subjects were classified as high-baseline or low-baseline subjects. Baseline alpha density, alpha density during training, and subjective mood were all considered as continuous variables. The results of the present study indicate that biofeedback of the cortical alpha rhythm is neither a sufficient nor a necessary condition for changes in subjective mood. In addition, the type of instructions designed to set subjects for positive or negative alterations in subjective states is predictive of changes in subjective state reported during alpha biofeedback training as well as of success at controlling and changing EEG during feedback training. The data presented here permit a direct examination of the actual relationship of EEG changes to changes in subjective mood state. Similar shifts in subjective mood state can be obtained with either increases or decreases in alpha activity. Further, both positive and negative subjective experiences can be associated with increases in alpha activity.
