The role of physiological arousal in time perception: psychophysiological evidence from an emotion regulation paradigm

Time perception, crucial for adaptive behavior, has been shown to be altered by emotion. An arousal-dependent mechanism is proposed to account for such an effect. Yet, physiological measure of arousal related with emotional timing is still lacking. We addressed this question using skin conductance response (SCR) in an emotion regulation paradigm. Nineteen participants estimated durations of neutral and negative sounds by comparing them to a previously memorized duration. Instructions were given to attend either to temporal or to emotional stimulus features. Attending to emotion with negative sounds generated longer subjective duration and greater physiological arousal than attending to time. However, a shared-attention condition showed discrepancy between behavioral and physiological results. Supporting the idea of a link between autonomic arousal and subjective duration, our results however suggest that this relation is not as direct as was expected. Results are discussed within recent model linking time perception, emotion and awareness.     

Hunger, eating, and ill health

Humans and other warm-blooded animals living with continuous access to a variety of good-tasting foods tend to eat too much and suffer ill health as a result--a finding that is incompatible with the widely held view that hunger and eating are compensatory processes that function to maintain the body's energy resources at a set point. The authors argue that because of the scarcity and unpredictability of food in nature, humans and other animals have evolved to eat to their physiological limits when food is readily available, so that excess energy can be stored in the body as a buffer against future food shortages. The discrepancy between the environment in which the hunger and eating system evolved and the food-replete environments in which many people now live has led to the current problem of overconsumption existing in many countries. This evolutionary perspective has implications for understanding the etiology of anorexia nervosa.

Constructions of emotion: Discrepancy,arousal, and mood

An interactive adventure-type computer game was used to explore the constructive components of emotional experience — sympathetic nervous system arousal and evaluative cognitions — postulated by discrepancy/evaluation theory. Manipulations of expectations produced significant and large heart rate changes for both positive and negative discrepancies. Autonomic response also reflected the degree of interruption/discrepancy produced by an event. Negatively toned (discrepant) events tended to produce significant intensity and higher overall autonomic arousal. In addition, subjects' intensity of experience was related to their autonomic response.The research and preparation of this report were supported by a grant from the Spencer Foundation.

Assessment of Parents,Couples, and Families in Dialectical Behavior Therapy

Family intervention in Dialectical Behavior Therapy (DBT) is a core part of multiple required functions of DBT, providing opportunities for skill training (including relationship-specific skills that are not covered in individual DBT), skill generalization, and direct intervention into the social and family environment. In order to intervene with parents, partners and other family members efficiently and effectively, therapists must first conduct a careful assessment. The core relationship transaction of emotion vulnerability/dysregulation and inaccurate expression leading to invalidating responses (and vice versa) is highlighted, as are the treatment targets in DBT with families, which inform assessment targets. Then, two core assessment procedures are explored, with clinical examples: (a) conducting “double chain” analyses, demonstrating how one person’s social or relationship responses affect the other’s emotional arousal (and vice versa); and (b) direct behavior observation of family interactions, which allow treatment targets to be identified efficiently. These two assessment strategies may also be combined. Implications for family interventions are discussed.     

Love and Power,and the Development of the Brain,Mind, and Agency

In drawing on my own research and collaborative work with Karl Pribram, I show that love (affective attachment) and power (social control) play a central role in psychosocial evolution. When these relations are coupled in a self-regulating system of cooperative interactions, brain growth is stimulated, mind and agency develop, and stable forms of collective social organization are generated. Focusing on the endogenous dynamics of social collectives, the article is organized in four parts. (A "social collective" is defined as a durable arrangement of relations among two or more individuals that is distinguished by shared membership and collaboration in relation to a common function or goal.) Part I summarizes evidence from developmental neuropsychology and social science to show that stable psychosocial organization, across the human life span, is associated with social interaction organized along two dimensions. One dimension involves love, positive affective attachment, and the second involves power, social regulation of the aroused affective energy. Part II draws on Piaget's theory of cooperation and Bradley and Pribrams' theory of communication to describe how mind and agency are generated, and how stable organization is produced, respectively, from the relations involved in the arousal and regulation of affective energy. Combining elements of the two theories, Part III presents a sketch of a holographic model of collective organization in which goal-directed behavior is generated by a feed-forward process involving imaging and information processing of interaction along the two dimensions. Part IV shows how the model accounts for the emergence of human agency within the context of a more general evolutionary theory, such as Laszlo's. The article concludes with a discussion of my approach for building a "fully human theory of evolution."     

On the perpetuation of ignorance: system dependence, system justification, and the motivated avoidance of sociopolitical information

How do people cope when they feel uninformed or unable to understand important social issues, such as the environment, energy concerns, or the economy? Do they seek out information, or do they simply ignore the threatening issue at hand? One would intuitively expect that a lack of knowledge would motivate an increased, unbiased search for information, thereby facilitating participation and engagement in these issues-especially when they are consequential, pressing, and self-relevant. However, there appears to be a discrepancy between the importance/self-relevance of social issues and people's willingness to engage with and learn about them. Leveraging the literature on system justification theory (Jost & Banaji, 1994), the authors hypothesized that, rather than motivating an increased search for information, a lack of knowledge about a specific sociopolitical issue will (a) foster feelings of dependence on the government, which will (b) increase system justification and government trust, which will (c) increase desires to avoid learning about the relevant issue when information is negative or when information valence is unknown. In other words, the authors suggest that ignorance-as a function of the system justifying tendencies it may activate-may, ironically, breed more ignorance. In the contexts of energy, environmental, and economic issues, the authors present 5 studies that (a) provide evidence for this specific psychological chain (i.e., ignorance about an issue → dependence → government trust → avoidance of information about that issue); (b) shed light on the role of threat and motivation in driving the second and third links in this chain; and (c) illustrate the unfortunate consequences of this process for individual action in those contexts that may need it most.     

唤醒定义探析及其认知神经生理基础

唤醒是衡量机体清醒程度和做出反应前准备程度的指标, 其水平可从睡眠到觉醒的连续体上变化, 具有独特的生理机制与神经回路。由于唤醒与情绪关联密切, 唤醒度这个概念常被认为等同于情绪强度, 但情绪强度实际上是唤醒和效价的和向量。受到Lazarus提出的“刺激”定义情绪思想的启发, 对唤醒的内含和心理机制进行了探析, 发现对不符合预期刺激出现的紧急准备是唤醒系统的主要功能, 预期性相关机制是唤醒的重要认知加工机制。其它因素(刺激属性、个体差异等)可能存在以下影响唤醒的原因：改变处理刺激时所需的资源量、影响预期机制。未来研究可从心理唤醒与生理唤醒的关系、唤醒的测量方法、唤醒度与情绪强度的关系、人类临床精神疾病的唤醒特征等角度推动唤醒的基础和应用研究。     

Cognitive and physiological indices of sexual arousal in homosexual,bisexual, and heterosexual males

Cognitive and physiological indices of sexual arousal were investigated utilizing groups of homosexual, bisexual, and heterosexual subjects (ten subjects per group) who were presented both homosexual and heterosexual films and slides. The results indicated that both homosexual and heterosexual subjects were able to estimate accurately their degree of erection to the erotic stimuli. Bisexual subjects, however, showed a large discrepancy between the magnitude of actual erection and verbally reported estimates of penile tumescence. In terms of physiological arousal, the erectile responses of the homosexual and bisexual groups were indistinguishable, a finding which questions the existence of male bisexuality as distinct from homosexuality or as a different sexual orientation in males.     

The Effects of Elevated Arousal and Mood on Maximal Strength Performance in Athletes

Optimal arousal models contend that high arousal contributes to inhibited athletic performance, whereas there is reversal theory research which indicates that high positive arousal may enhance performance. To test these claims, 22 male and 6 female elite athletes were induced into high arousal telic (goal-directed) and high arousal paratelic (non goal-directed, process focussed) motivational states and tested on a standard hand strength task. Personalized guided imagery techniques and paced breathing were used to change psychological and physiological arousal. Significant increases in strength performance occurred when arousal was high and experienced as pleasant excitement in the paratelic condition (i.e., high positive arousal). Heart rate and other indicators of parasympathetic and sympathetic nervous system activity were not found to mediate between psychological arousal and performance. Where athletic performance requires maximal motor strength over a short period, performance benefits of high arousal may be maximized by restructuring motivational state.     

Type A personality and discrepancies between self-report and heart-rate responses to stress

The present study was done to replicate previous findings on the discrepancy between Type A persons' self-reports of stress and their physiological arousal. An attempt was made to clarify whether this discrepancy was due to Type A persons' denial of their arousal or an inability to discriminate physiological change. The students' version of the Jenkins Activity Survey was administered to 30 female students, aged 19 to 43 yr., who then performed a digit recall. A Multiple Affect Adjective Check List and a self-report questionnaire were used to measure affective reactions. Analysis showed that Type A individuals had higher heart-rate responses to stress but did not report greater subjective arousal. These results replicated the previously reported discrepancy. The current findings are somewhat consistent with an explanation based on discrimination.     

Effects of Violent Versus Nonviolent Video Games on Children's Arousal, Aggressive Mood, and Positive Mood

This study investigated the relationship between violent video games and children's mood. A total of 71 children aged 8 to 12 years played a paper-and-pencil game, a nonviolent video game, and a violent video game. Results indicate that arousal, as measured by heart rate and self-reported arousal, increased significantly after playing the violent video game, as compared with the other two game conditions, with girls reporting more arousal than did boys. There was no significant increase in aggressive mood scores for either boys or girls after playing the violent game. Positive mood, as measured by positive affect, showed no significant increases or decreases after playing either video game. However, positive mood, as measured by general mood, showed a significant increase after playing the violent game for both boys and girls, but only as compared with the paper-and-pencil game. Results are interpreted in terms of social learning and cognitive information processing theories of aggression.     

Two Contrasting Explanations of Involvement Violations:

Among the theories that address the impact of variations in immediacy behaviors during ongoing interactions are expectancy violations (EV) and discrepancy arousal (DA) theories. This study of the effects of violations of expectations on arousal, reciprocity, and compensation in the medical practitioner-patient relationship contrasts EV predictions with DA predictions. EV theory predicts that given a communicator with high reward valence, high and very high involvement (including touch and close proximity) should be met with reciprocation (increased involvement), and low and very low involvement should be met with compensation (increased involvement). DA theory predicts compensating very high involvement with decreased involvement, reciprocating high involvement with increased involvement, compensating low involvement with increased involvement, and reciprocating very low involvement, with decreased involvement. Results supported neither theory as all involvement changes were met with reciprocity. Additionally, although all violations/discrepancies were followed by changes in arousal, size of arousal change was not monotonically related to size of involvement change, as predicted by DA theory. Finally, although positive versus negative emotional experiences were not related to physiological indicators of arousal change, size of involvement change was directly related to the experience of positive and negative emotions. Thus, it appears that involvement change size directly predicts emotional experience and is not mediated by arousal change.     

Self-discrepancy and chronic social self-consciousness: Unique and interactive effects of gender and real–ought discrepancy

Drawing on theories of self-discrepancy and self-focused attention, two studies tested the associations between self-discrepancy and chronic social self-consciousness (CSSC), a trait-like view of the self as a social object. In Study 1, hierarchical regression analyses demonstrated that real/own-ought/other discrepancy was uniquely associated with CSSC independent of impression management, neuroticism, and real/own-ideal/own discrepancy among women but not men. In Study 2, the unique relation between real/own-ought/other discrepancy and CSSC was replicated in a larger sample of women after controlling several robust competing variables including the importance of physical appearance. Discussion considers real/own-ought/other discrepancy as a unique psychological predictor of taking a chronic view of the self as a social object among women.     

More than a feeling: Emotional cues impact the access and experience of autobiographical memories

Remembering is impacted by several factors of retrieval, including the emotional content of a memory cue. Here we tested how musical retrieval cues that differed on two dimensions of emotion—valence (positive and negative) and arousal (high and low)—impacted the following aspects of autobiographical memory recall: the response time to access a past personal event, the experience of remembering (ratings of memory vividness), the emotional content of a cued memory (ratings of event arousal and valence), and the type of event recalled (ratings of event energy, socialness, and uniqueness). We further explored how cue presentation affected autobiographical memory retrieval by administering cues of similar arousal and valence levels in a blocked fashion to one half of the tested participants, and randomly to the other half. We report three main findings. First, memories were accessed most quickly in response to musical cues that were highly arousing and positive in emotion. Second, we observed a relation between a cue and the elicited memory’s emotional valence but not arousal; however, both the cue valence and arousal related to the nature of the recalled event. Specifically, high cue arousal led to lower memory vividness and uniqueness ratings, but cues with both high arousal and positive valence were associated with memories rated as more social and energetic. Finally, cue presentation impacted both how quickly and specifically memories were accessed and how cue valence affected the memory vividness ratings. The implications of these findings for views of how emotion directs the access to memories and the experience of remembering are discussed.     

Cognitive dissonance as a function of self-esteem and logical inconsistency

An experiment was conducted to test the importance of self-esteem in the arousal of cognitive dissonance. Recently, Aronson (1969) suggested that the reason an attitude-discrepant speech can arouse dissonance is that it is an indecent act committed by an individual who likes to think of himself as a good and decent person. Looking at counterattitudinal behavior as a discrepancy with one's self-concept rather than as a logical discrepancy between behavioral and attitudinal cognitions differs from Festinger and Carlsnuth's (1959) original notion In the experiment reported, subjects volunteered to take a personality inventory and received either neutral, very favorable, or very unfavorable feedback In this way, subjects' level of self-esteem was raised or lowered Following this procedure, subjects were induced to record a speech that was known to be discrepant with their private beliefs. They were offered either a small or a large inducement for their statements. It was predicted that, regardless of their level of self-esteem, subjects would manifest the inverse relationship between incentive magnitude and attitude change predicted by dissonance theory The major analysis of the results, and the concomitant internal analysis, generally supported the prediction With one qualification, the results were held to be consistent with Festinger and Carlsmith's version of dissonance arousal and inconsistent with the self-esteem analysis     

Social facilitation in chickens: A different level of analysis

An assumption of the arousal (D × H) model of social facilitation effects is that in an otherwise constant stimulus situation the simple presence or absence of a conspecific has a quantitative influence on the D component, and that the habit hierarchy in the situation (H) is unaffected. However, certain evidence from avian subjects seemed inconsistent with the multiplicative effects predicted by the model, and experiments were conducted with the aim of resolving this discrepancy. In general, chickens were tested for consummatory responses in the company of companions, in isolation, or in the company of strangers. Clear findings emerged from these tests that showed that only the companion conditions were “facilitative”. Under the other test conditions there were qualitative (as opposed to merely quantitative) shifts in responses. Apparently, the different social test conditions evoked qualitatively different response hierarchies, and “facilitation” reflected this sort of shift rather than simple quantitative changes in arousal (D) across conditions. It was argued, therefore, that the appropriate level of analysis for facilitation effects for animals in a free response situation is not within the (D × H) envelope, but rather at the level of S (stimulus situation) in the S → (D × H) → R formulation. Implications for the analysis of social facilitation effects in humans were discussed.     

Mousekilling,intermale fighting,and conditioned emotional response in rats

Several possible relationships between two forms of aggression in rats were studied. First, mouse killing and spontaneous intermale fighting were found to be correlated. Rats which attacked other rats were those most likely to kill mice. To determine whether aggressive and nonaggressive rats were also differentially responsive to other situations involving emotional arousal, but not aggression, mouse-killers and nonkillers were compared in a conditioned emotional response (CER) situation. Mouse-killers showed greater suppression to the conditioned stimulus (CS) and to the situational cues of the apparatus. Therefore, a common arousal mechanism may underlie a number of diverse agonistic responses. Nevertheless, extensive mouse-killing experience did not increase the tendency of rats to fight with either adult males or juvenile males.     

Irreplaceability and the intentionality of sexual arousal

Philosophers writing about the intentionality of sexual arousal have generally been of two minds. One approach likens it to an appetite that aims at a distinctive type of gratification. A second treats it as the attempt, through a process of embodiment, to unite with a transcendental self. The first model lays stress on the fungibility of the object of sexual desire: the body and certain of its parts. The latter sees arousal as burdened with impossible satisfaction conditions based on an extravagant metaphysics of the self. In this paper, I defend an account that emphasizes the cooperative element in arousal and assimilates its content to that of other such social activities. This preserves the central place of the self in the intentionality of arousal in a way that is metaphysically benign and that ultimately avoids treating sex as a sui generis form of human interaction.
