Conditioning of counter-empathetic emotional responses

The present research tested the hypothesis that the quality of an observer's vicarious emotional response, as measured by autonomic, expressive, and self-report indexes, is a function of the observer's conditioning history with particular facial expressive displays of emotion. It was predicted that conditions of congruence (Symmetry) between the affective expression of a model and the outcome (shock or reward) presented to an observer would enhance initial empathetic responses, but that conditions of incongruence (Asymmetry) between the model's displays and observer's outcomes would lead to counter-empathetic responses. These changes in the quality of observers' vicarious emotional responses should generalize to a test phase when no rewards or punishments are presented to observers. The results for all measures were consistent and indicate that asymmetric conditioning modified the initial empathetic responses of observers to either counter-empathetic responses or indifference. On the other hand, symmetric conditioning enhanced observers' initial empathetic responses. These effects were evident in the test phase when no reinforcements were administered to the subject. The results are consistent with the theoretical assumption that facial expressions of emotion can acquire meaning and hedonic valence because of their predictive significance and thus can function as conditioned stimuli capable of evoking empathetic and counter-empathetic emotional responses.     

Effects of perceived similarity on vicarious emotional conditioning

The present experiment tested the hypothesis that perceived similarity between observers and models enhances vicarious emotional conditioning. Subjects were led to believe that they were either similar to the model in beliefs and attitudes, different from him or were given no information about him. They then underwent a vicarious classical conditioning procedure by witnessing the model express pain reactions in conjunction with a neutral stimulus. Observers developed emotional reactions to the neutral stimulus alone after seeing it paired with modeled pain expressions. Preceived similarity, however, had no significant effect on either the level of vicarious conditioning or the rate of extinction. Subjects who had no information concerning the model displayed stronger autonomic responses to the model's pain expressions, and more frequent and intense autonomic responses to the conditioned stimulus during tests for acquisition and extinction. In correlational analyses, subjects in the latter condition also yielded a significant positive relationship between self-reported arousal and vicarious emotional conditioning. The obtained findings were interpreted in terms of the emotion arousing properties of unfamiliarity.     

Effects of vicarious consequences on imitation and recall: Some developmental findings

Two experiments were conducted using a multiple-item list in which each item consisted of a pair of pictures. The model indicated which member of each pair she preferred and was either positively reinforced, negatively reinforced, or received neutral consequences. The S then indicated his preferences (imitation test). Following the imitation test, each S was asked to recall the model's choices. Age was an independent variable in both experiments. Imitation scores of the children, preschool to sixth-grade age range, were strongly influenced by differential vicarious reinforcement. Vicarious reward increased imitation and vicarious punishment decreased it. College students' imitation scores were only minimally influenced by differential vicarious reinforcement. Within- and between-subjects variations of vicarious reinforcement had similar effects. Recall scores were surprisingly high and were not significantly influenced by differential vicarious reinforcement. Interestingly, age and percentage of correct recall were negatively correlated.     

Behavioral inhibition and amplification during emotional arousal: a comparison of two age groups

This study investigated age differences in the ability to suppress and amplify expressive behavior during emotional arousal. Young and old participants viewed 3 film clips about medical procedures while their behavioral, autonomic, and subjective responses were recorded. Half of the participants viewed all 3 films without additional instructions; the other half was asked to suppress and amplify their behavioral expression during the 2nd and 3rd films. Except for heart rate, suppression and amplification produced similar patterns of autonomic activation. Neither suppression nor amplification had effects on self-reported emotion. There were no age differences in the ability to suppress or amplify emotional expression or in their physiological or subjective consequences. Considering that older people's unregulated reactivity was lower than that of young adults, suppression may have been easier and amplification more difficult for older adults. Voluntary emotion regulation might be one domain of human performance that is spared from age-related losses.     

Effects of differentially modeled stimuli on vicarious autonomic arousal

The present study examined effects of variations in modeled pain cues on level of vicarious arousal, using heart rate and blood-volume amplitude as psychophysiological measures. Students were assigned randomly to one of four groups in which they either (a) underwent directly the cold-pressor test, (b) observed a model exposed to the cold-pressor test and expressing pain by facial and bodily movements, (c) heard only the modeled verbal expressions of pain, or (4) observed the model express neither verbal expressions nor physical movements while undergoing the painful stimulation. The results show aversive stimulation increases heart rate whereas vicarious aversive stimulation produces reductions in heart rate. The deceleration of heart rate was not found in response to all three forms of modeling. Both direct and vicarious aversive stimulation produced decreases in the amplitude of vasomotor responses. The size of the decrement between direct stimulation and the minimal modeling condition of vicarious arousal showed significant differences, but differences between direct stimulation and the maximal modeling condition were not significant. The vasoconstriction was found in response to two forms of modeling.     

Imitation as a function of response commonality,serial order,and vicarious punishment

The effects of response commonality, serial order of modeled responses, and vicarious punishment on young boys' recall and acceptance of 20 commodity prefereces of an adult were examined in a 2 (common dimension vs no-common dimension) × 2 (vicarious punishment vs no-vicarious consequences) × 2 (recall or acceptance test) × 5 (response-block) factorial experiment. As predicted, the presence of a common dimension resulted in improved recall of the modeled responses, vicarious punishment was more effective under common dimension than no-common dimension conditions, and a serial order effect for recall of the modeled responses was obtained. The overall pattern of results is discussed in terms of the conceptualization that imitation requires both that the observer (1) has acquired and retained the model's responses and (2) has been placed in circumstances which favor activating this learning into overt performance.     

Autonomic and subjective responsivity to emotional images in people with dissociative seizures

People with dissociative seizures (DS) report a range of difficulties in emotional functioning and exhibit altered responding to emotional facial expressions in experimental tasks. We extended this research by investigating subjective and autonomic reactivity (ratings of emotional valence, arousal and skin conductance responses [SCRs]) to general emotional images in 39 people with DS relative to 42 healthy control participants, whilst controlling for anxiety, depression, cognitive functioning and, where relevant, medication use. It was predicted that greater subjective negativity and arousal and increased SCRs in response to the affective pictures would be observed in the DS group. The DS group as a whole did not differ from controls in their subjective responses of valence and arousal. However, SCR amplitudes were greater in ‘autonomic responders’ with DS relative to ‘autonomic responders’ in the control group. A positive correlation was also observed between SCRs for highly arousing negative pictures and self‐reported ictal autonomic arousal, in DS ‘autonomic responders’. In the DS subgroup of autonomic ‘non‐responders’, differences in subjective responses were observed for some conditions, compared to control ‘non‐responders’. The findings indicate unaffected subjective responses to emotional images in people with DS overall. However, within the group of people with DS, there may be subgroups characterized by differences in emotional responding. One subgroup (i.e., ‘autonomic responders’) exhibit heightened autonomic responses but intact subjective emotional experience, whilst another subgroup (i.e., ‘autonomic non‐responders’) seem to experience greater subjective negativity and arousal for some emotional stimuli, despite less frequent autonomic reactions. The current results suggest that therapeutic interventions targeting awareness and regulation of physiological arousal and subjective emotional experience could be of value in some people with this disorder.     

Processing of observed pupil size modulates perception of sadness and predicts empathy

Facial autonomic responses may contribute to emotional communication and reveal individual affective style. In this study, the authors examined how observed pupillary size modulates processing of facial expression, extending the finding that incidentally perceived pupils influence ratings of sadness but not those of happy, angry, or neutral facial expressions. Healthy subjects rated the valence and arousal of photographs depicting facial muscular expressions of sadness, surprise, fear, and disgust. Pupil sizes within the stimuli were experimentally manipulated. Subjects themselves were scored with an empathy questionnaire. Diminishing pupil size linearly enhanced intensity and valence judgments of sad expressions (but not fear, surprise, or disgust). At debriefing, subjects were unaware of differences in pupil size across stimuli. These observations complement an earlier study showing that pupil size directly influences processing of sadness but not other basic emotional facial expressions. Furthermore, across subjects, the degree to which pupil size influenced sadness processing correlated with individual differences in empathy score. Together, these data demonstrate a central role of sadness processing in empathetic emotion and highlight the salience of implicit autonomic signals in affective communication.     

Conditioning of electrodermal responses through vicarious instigation and through perceived threat to a performer

Abstract.— In order to demonstrate vicarious classical conditioning, and to investigate the necessity of vicarious instigation for vicarious conditioning of skin conductance responses, two groups of 32 students each observed a performer ( P ) allegedly trying to solve easy and difficult number series displayed for both the P and the observers ( Os ). Difficult problems served as CS+ and easy ones as CS-for os in both groups; indicated shock to the P as unconditioned stimulus (UCS) for one group, and perceived threat of shock to P as UCS for the other. Within the two groups half of the os were instructed to empathize with the P , whereas the other half was instructed just to watch her movements. The results demonstrated vicarious instigation and conditioning for the group having indicated shock as UCS, and conditioning without instigation for the group having perceived threat of shock as UCS. Since results for the conditioned response and the vicariously instigated response go beyond earlier interpretations, a theoretical elaboration in the cognitive direction is argued for.     

Informational analysis of imitation: Further comments

An informational analysis of imitation as proposed by Liebert and Fernandez (1970a) is examined. Based on the Liebert and Fernandez data and statistical procedures, as well as inconsistent findings in other studies in the area, at least certain components of the informational heuristic would appear to have serious limitations. In particular, the proposal that both vicarious reward and punishment, relative to no vicarious consequences, will increase recall of the model's acts is questioned.     

Acquisition of phobias and anxiety response patterns in clinical patients

The ways in which phobic patients (N = 106; animal-, social- and claustrophobics) acquired their phobias were investigated in the present study. The results showed that a large majority (58%) of the patients attributed their phobias to conditioning experiences, while 17% recalled vicarious experiences, 10% instructions/information and 15% could not recall any specific onset circumstances. There was no clearcut relationship between the ways of acquisition and anxiety components (subjective, behavioral, physiological), nor did the conditioning and indirectly acquired phobias differ in severity. However, some interesting trends emerged in the data, showing that animal phobics who recalled conditioning experiences to a larger extent also responded physiologically. For patients with indirect onset experiences (for all three types of phobias) the reverse was true, i.e. they responded to a larger extent in a cognitive-subjective way, rather than with increased physiological arousal.     

Effects of emotional valence and arousal manipulation on eyeblink classical conditioning and autonomic measures

Using a classical eyeblink conditioning paradigm, we have previously shown that the rate of acquisition of a conditioned response may be manipulated by engaging subjects in background tasks of varying complexity concurrent to conditioning. To further examine the influence of the background environment on conditioning, a picture set designed to elicit emotional responses, the International Affective Picture System (IAPS), was presented to subjects during classical eyeblink conditioning. The results suggest that eyeblink conditioning does appear to be sensitive to contextual manipulations of arousal. Pictures rated as very arousing were found to engage subjects enough to enhance learning, although not to the point that autonomic functions were significantly altered between picture groups. We suggest that group differences in learning may be a result of either novelty of, or vigilance to, interesting pictures rather than as a direct result of physiological arousal.     

Effects of nonverbal dissimulation on emotional experience and autonomic arousal.

Three studies are reported that examine the relationship between the nonverbal display of emotional affect and indices of the emotional state. Subjects were asked either to conceal or to exaggerate the facial display associated with the anticipation and reception of painful shocks that varied in intensity. Both self-reports of shock painfulness and skin conductance measures of emotional response showed significant changes paralleling the changes induced in expressive behavior; that is, the suppression of expressive responses decreased the magnitude of phasic skin conductance changes and subjective reports of painfulness as compared to the free expression or exaggeration of pain-related expressive response. The effects were obtained for shocks of varying intensities and for both male and female subjects. The findings support theories of emotion that assume that expressive responses serve a self-regulatory as well as a social-communicative function, and further suggest that the self-regulation is mediated neurally, rather than via a process of self-attribution. Finally, the results highlight the need for research on dissimulation in social interaction to consider the effects of acting upon the actor, as well as its effects upon the inferences of observers.

We suggest that group differences in learning may be a result of either novelty of, or vigilance to, interesting pictures rather than as a direct result of physiological arousal.     

The relation of vicarious to direct instigation and conditioning of electrodermal responses

Abstract.— Three groups with 16 Ss each and run in pairs, participated in a differential, successive components, long interstimulus interval conditioning paradigm with the skin conductance response as dependent variable. For the problem solving group the task was described as guessing which of two lamps (CS₂s) would follow after two different tones (CS₁s). In the observer group they were further informed that the other subject in the pair, the model, would receive shocks at CS+ offset, which actually was the case for the model group. Skin conductance responses were scored in five intervals during and after the non-overlapping presentation of the two CSs with a duration of 8 sec each. The results indicated no differentiation in any interval for the problem-solvers, and parallel instigation to shock and threat of shock, and conditioning in the observer and model groups, with the exception of conditioning in the 1st interval for observers only. The results were interpreted as parallel instigation and conditioning between vicarious and direct learning, the reported difference being due only to different UCS-intensities causing a blocking of first-order conditioning in the model but not in the observer group.     

The development of skin conductance fear conditioning in children from ages 3 to 8 years

Although fear conditioning is an important psychological construct implicated in behavioral and emotional problems, little is known about how it develops in early childhood. Using a differential, partial reinforcement conditioning paradigm, this longitudinal study assessed skin conductance conditioned responses in 200 children at ages 3, 4, 5, 6, and 8 years. Results demonstrated that in both boys and girls: (1) fear conditioning increased across age, particularly from ages 5 to 6 years, (2) the three components of skin conductance fear conditioning that reflect different degrees of automatic and controlled cognitive processes exhibited different developmental profiles, and (3) individual differences in arousal, orienting, and the unconditioned response were associated with individual differences in conditioning, with the influence of orienting increasing at later ages. This first longitudinal study of the development of skin conductance fear conditioning in children both demonstrates that children as young as age 3 years evidence fear conditioning in a difficult acquisition paradigm, and that different sub-components of skin conductance conditioning have different developmental trajectories.     

A hierarchy of information sources for inferring emotional reactions

The ability of children and adults to infer emotional reactions from different sources of information was investigated. Preschoolers (mean age, 4–9), second graders (mean age, 4–9), and college students were asked to infer emotional reactions from verbally presented stories in which sources of information occurred either singly, in conflict, or in congruence. The sources investigated were situational (the protagonist's social or physical situation), normative (the dispositions of a group to which the protagonist belongs), and personal (the dispositions of the protagonist in particular). Subjects indicated the protagonist's emotional reaction to an event in the story by choosing one of three facial expressions, representing happy, upset, and afraid. A hierarchy of sources for making emotional inferences was found at all three grade levels: personal information was preferred over normative information, and both were dominant over situational information. The relevance of present methods and findings to the study of the development of “empathy” is discussed.     

Effects of repeated exposure to sexually violent or nonviolent stimuli on sexual arousal to rape and nonrape depictions

The major purpose of this investigation was to examine the effects of repeated exposure to sexually violent stimuli (SVS) in relatively ‘naturalistic settings’ on sexual arousal to rape and nonrape stimuli. Repeated exposure effects using nonviolent erotica were also examined. Sixty-nine male Ss participated in the study. A preexposure session was conducted in which Ss were exposed to written and pictorial depictions of rape and mutually-consenting intercourse. Based on Ss' penile tumescence to these depictions, they were classified as either Force-oriented, Nonforce-oriented or Unclassifiable. Subsequently, Ss were randomly assigned to sexually violent (SVS), sexually nonviolent (SNVS) or control conditions within each force-orientation group. Those assigned to the SVS condition were then exposed to 10 SVS including feature-length films and written and pictorial depictions over a period of 4 weeks. Ss in the SNVS condition were exposed to 10 similar media presentations depicting sexually nonviolent activities only. Ss in the control condition were not exposed to any stimuli during this 4-week period. Soon after completion of the exposure phase, Ss returned for a postexposure laboratory session in which they were presented with four depictions that were similar in theme to those in the preexposure session. Penile tumescence scores and self-reports of sexual arousal were obtained. Results revealed that, for Force-oriented Ss, those exposed to either SVS or SNVS were less aroused to the rape depictions in the postexposure session than those in the control condition. A similar pattern occurred with the nonrape depictions for these Ss, though it was considerably less pronounced. No evidence of a similar ‘satiation’ pattern was obtained for either Nonforce-oriented or Unclassifiable Ss, with these Ss showing no significant differences among the three exposure conditions. The findings are discussed in the context of cognitions, personality differences, conditioning processes, stimulus parameters and response habituation theories. Social and clinical implications are also discussed.     

Extraversion and sleep: A psychophysiological study of the arousal hypothesis

In order to examine Eysenck's (1967) hypothesis concerning the relationship between extraversion and arousal, autonomic measures were taken from introverts and extraverts immediately before sleep and during 6 hr of sleep. Introverts and extraverts did not differ in heart rate (HR) or skin-potential response rate (SPR) during the pre-sleep period. A variety of sleep-related measures of arousal provided no strong support for the hypothesis that introverts are more aroused than extraverts. The only consistent autonomic difference between introverts and extraverts during sleep was a tendency for introverts to have higher SPRs in the second 3 hr of the night. The results are discussed in terms of the level of environmental stimulation present in the experimental conditions, and suggestions are made for future sleep studies of the relationship between extraversion and arousal.     

Correspondence and mediational properties of the Fishbein model: An application to adolescent alcohol use

The generalizability of the Fishbein model for behavior prediction was extended to a new field behavior, alcohol drinking by adolescents. The model's two components (i.e., attitudes and normative beliefs) varied in their predictive importance depending on the behavior's situational context. Following this field demonstration, two issues related to properties affecting the model's predictive effectiveness were investigated. First, it was found that the predictability of alcohol-drinking intentions (BI) declined when attitudes (A_act) and normative beliefs (NB) did not correspond with BI in terms of alcohol type (beer, liquor, or wine) and drinking situation (home, party, or pub). A second experiment tested the hypothesis that exogenous variables (those other than A_act and NB) would have a direct influence on BI. A comprehensive test was provided within the context of Jessor's multivariate predictive system for adolescent alcohol use. Present data indicate only a marginal increase in explained variance occurred when applying this system, thereby generally indicating the sufficiency of the Fishbein model's two components.
