意识状态改变的心理生理学理论与实证研究

从“意识状态”解释人类意识的本质是当前意识心理学研究的一个重要取向。研究意识状态改变(ASC)的物质生理基础具有十分突出的理论和临床实践意义。意识状态改变可以分为自发、物理和生理原因、心理方式和疾病引起这样四个方面,不同类型的意识状态改变可以从激活、意识域、自我觉察和感觉振荡四个维度进行综合归类和分析。不仅脑结构功能状态、脑动力的暂时变化、神经化学过程和新陈代谢过程等因素影响着人的意识经验改变状态,而且环境变化、心理活动和自我控制及技巧也可以暂时改变人的意识功能状态。

Having it Both Ways: Consciousness, Unique Not Otherworldly

I respond to Chalmers’ (2006, 2010) objection to the Phenomenal Concept Strategy (PCS) by showing that his objection is faced with a dilemma that ultimately undercuts its force. Chalmers argues that no version of PCS can posit psychological features that are both physically explicable and capable of explaining our epistemic situation. In response, I show that what Chalmers calls ‘our epistemic situation’ admits either of a phenomenal or of a topic-neutral characterization, neither of which supports Chalmers’ objection. On the one hand, if our epistemic situation is characterized phenomenally, then Chalmers’ demand that PCS should explain our epistemic situation is misplaced. PCS can explain our epistemic situation only if there is a reductive explanation of consciousness. But according to PCS, no reductive explanation of consciousness can be given. On the other hand, if our epistemic situation is characterized topic-neutrally, then PCS is not only physically explicable, but it also explains our epistemic situation. Either way, PCS is safe.     

Viewpoint-dependent Priming Effects in the Perception of Human Actions and Body Postures

The identification of human actions and body postures viewed from different viewpoints was examined in four long-term priming experiments with static pictures of a human model. In Experiments 1 and 2 participants had to name or describe the pictures, and in Experiments 3 and 4 participants had to decide whether the pictures showed a possible or impossible body pose. Reliable priming effects were obtained only when priming and primed action or pose shared the same in-depth orientation (Experiments 1 and 4) and left-right reflection (Experiments 2 and 3). Having seen the same action or pose in a different orientation did not reliably facilitate identification performance later on. Also, there was no priming for poses that are impossible to perform with a human body, not even when an identical same-view prime was used. These findings suggest that the stored representations that mediate the identification of human actions and postures are viewpoint specific.     

《希伯来圣经》中的神人约——仪式、性质及团体意识

《希伯来圣经》中神人约的订立需要举行特定的仪式。尽管立约由神一方提出,神人约的完成却需要双方的努力。神人约具有双向性,它反映了神人双方的相互需要。神人约中蕴涵着深厚的团体意识,它使以色列成为一个非常有凝聚力的民族整体。     

Body Image Scores and Varieties of Consciousness

Dreams, depersonalization experiences, daydreams, and autobiographies were compared in regard to barrier, penetration, and neutral imagery and action scores. Significant differences were found between these varieties of consciousness on all three scores. Only barrier scores showed significant differences between males and females.     

Confucian Ritual as Body Language of Self, Society, and Spirit

This article explains how li ?Y or ??ritual propriety?? is the ??body language?? of ren ?? or the authentic expression of our humanity. Li and ren are interdependent aspects of a larger creative human way (rendao ???) that can be conceptually distinguished as follows: li refers to the ritualized social form of appropriate conduct and ren to the more general, authentically human spirit this expresses. Li is the social instrument for self-cultivation and the vehicle of harmonious human interaction. More, li must mean something that is effectively communicated to others for an authentic, human (ren) interaction to occur. Li is the body language of ren in being the ritual vehicle for its?? expression; however, li is underdetermined by ren and so must be distinguished from it in on further grounds: authentic human activity must not just be equivocated with social convention because conclusively establishing whether a particular action is li (or is a truly ren action) is impossible. As a result, li is often confused with social power and privilege that is easier to empirically identify than ren conduct is, but this is a mistake since li has to express ren or it is not li at all. The inescapable ambiguity of li ?C an ambiguity that attaches to any language ?C can be critiqued by the Western view that sees something ??essential?? to the ??self,?? and that makes one a ??self?? in and of oneself and not in a way that depends on others. I show that such Western individualism ?C while resting on a fundamentally different way of thinking of being a person and living a good life ?C does not reduce Confucian ritual to being an instrument for social discrimination and subordination. My argument is indebted to twentieth-century philosophy of language in the West that offered the idea that some words are actions.     

Integrative Properties of the Pe1 Neuron, a Unique Mushroom Body Output Neuron

A mushroom body extrinsic neuron, the Pe1 neuron, connects the peduncle of the mushroom body (MB) with two areas of the protocerebrum in the honeybee brain, the lateral protocerebral lobe (LPL) and the ring neuropil around the α-lobe. Each side of the bee brain contains only one Pe1 neuron. Using a combination of intracellular recording and neuroanatomical techniques we analyzed its properties of integrative processing of the different sensory modalities. The Pe1 neuron responds to visual, mechanosensory, and olfactory stimuli. The responses are broadly tuned, consisting of a sustained increase of spike frequency to the onset and offset of light flashes, to horizontal and vertical movements of extended objects, to mechanical stimuli applied to the antennae or mouth parts, and to all olfactory stimuli tested (29 chemicals). These multisensory properties are reflected in its dendritic organization. Serial reconstructions of intracellularly stained Pe1 neurons using confocal microscopy reveal that the Pe1 neuron arborizes throughout all layers of MB peduncle with finger-like, vertically oriented dendrites. The peduncle of the MB is formed by the axons of Kenyon cells, whose dendritic inputs are organized in modality-specific subcompartments of the calyx region. The peduncular arborization indicates that the Pe1 neuron receives input from Kenyon cells of all calycal subcompartments. Because the Pe1 neuron changes its odor responses transiently as a consequence of olfactory learning, we hypothesize that the multimodal response properties might have a role in memory consolidation and help to establish contextual references in the long-term trace.     

Body Dissatisfaction in Adolescent Boys and Girls: Objectified Body Consciousness, Internalization of the Media Body Ideal and Perceived Pressure from Media

The aim of the present study was to examine a theoretical model describing the relationships between body shame and body surveillance (components of objectified body consciousness), internalization of the media body ideal, perceived pressure from media, body mass index and body dissatisfaction in Swiss adolescent boys and girls. A sample of 819 boys and 791 girls aged 14–16 years completed self-report measures of the mentioned concepts. As expected, girls had higher body shame and body surveillance than boys. Structural equation modelling supported the proposed model in both boys and girls. The findings suggest processes that may contribute to body dissatisfaction.     

Social Psychology and the Empirical Body: Rethinking the Relationship

Although social science work on the body has demonstrated its thorough socialisation, social psychology has barely recognised the mutual interdependence of the physical body and the social world. Accordingly, we propose that social psychology might be enriched and extended by detailed investigation of changes in the activity of the empirical body alongside processes of meaning-making during social interaction. We illustrate our proposal with a case study of changes in blood pressure during conversation, explored in conjunction with analyses using four discursive frames: gaining voice, identity negotiation, joint action/knowing of the third kind and positioning theory. We argue that this approach challenges the artificial separation of social psychology from other sub-disciplines, might inform social psychological analyses of emotion and belief and allows it to address substantive topics, such as psychopathology, which it typically largely excludes.     

Body Consciousness Across the Adult Years: Variations with Actual and Subjective Age

Age-related trends and predictors were explored with respect to three dimensions of adults’ body consciousness. Consistent with the notion that aging adults’ perceptions of their bodies are multidimensional and multidirectional, adults reported being more concerned about their external physical appearance (public body consciousness), more aware of their internal body sensations (private body consciousness), and more positive in their self-evaluations of their bodies (body competence). Moreover, consistent with the claim that such attitudes are multi-determined, the present research found that aging adults’ personal anxiety about aging and their subjective age identities were significant predictors of variations in their body consciousness. Moreover, the predictive value of these psychological variables rivaled the predictive value of chronological age.

Consciousness: a neurological perspective

Consciousness is a state so essentially entwined with human experience, yet so difficult to conceptually define and measure. In this article, we explore how a bidimensional model of consciousness involving both level of arousal and subjective awareness of the contents of consciousness can be used to differentiate a range of healthy and altered conscious states. These include the different sleep stages of healthy individuals and the altered states of consciousness associated with neurological conditions such as epilepsy, vegetative state and coma. In particular, we discuss how arousal and awareness are positively correlated in normal physiological states with the exception of REM sleep, while a disturbance in this relationship is characteristic of vegetative state, minimally conscious state, complex partial seizures and sleepwalking.     

Gender Differences in Undergraduates' Body Esteem: The Mediating Effect of Objectified Body Consciousness and Actual/Ideal Weight Discrepancy

Three hundred twenty-seven undergraduatemostlyEuropean American women and men were surveyed totest whether feminist theoryabout how women come to viewtheir bodies as objects to be watched (Objectified Body Consciousness or OBC) can be useful inexplaining gender differences in body esteem. The OBCscales (McKinley & Hyde, 1996) were demonstrated tobe distinct dimensions with acceptable reliabilities for men. Relationships between bodysurveillance, body shame, and body esteem were strongerfor women than for men. Women had higher surveillance,body shame, and actual/ideal weight discrepancy, andlower body esteem than did men. Multiple regressionanalysis found that gender differences in body esteemwere no longer significant when OBC was entered into theequation, supporting feminist theory about women's body experience.     

Objectified Body Consciousness in a Developing Country: A Comparison of Mothers and Daughters in the US and Nepal

Self-objectification (Fredrickson and Roberts 1997) has been related to negative psychological consequences in U.S. women. However, little cross-cultural research has been done. We compared convenience samples of American and Nepali women on two measures of self-objectification. Pairs of Nepali mothers and daughters (N?=?23) and pairs of U.S. mothers and daughters (N?=?24) completed a quantitative and a qualitative measure of self-objectification. Cultural and generational differences were found. Nepali women engaged in less self-surveillance than U.S. women. Older women engaged in less self-surveillance than younger women. Women in both cultures had high beliefs in their ability to control the body. An additional dimension of body consciousness, termed Functionality, was particularly important to younger Nepali women.     

Body on My Mind: The Lingering Effect of State Self-objectification

Objectification theory explicates a model in which women are socialized to view their own bodies as objects to be evaluated. In the current study, we used a 2 (self-objectification condition: swimsuit versus sweater)?×?2 (gender) factorial design to examine whether body-related thoughts continued after women were removed from a self-objectifying situation. Results showed that, compared to participants in the other three groups, women in the self-objectification condition listed more body-related thoughts during a free response task given after they had re-dressed. The amount of shame experienced during self-objectification mediated the relationship between self-objectification condition and lingering body-related thoughts. This study adds to the understanding of how the process of self-objectification works to maintain women’s focus on their appearance.     

Codependency: An Empirical Study from a Systemic Perspective

To empirically investigate the construct validity of codependency, differences between young adults on a measure of codependency on theoretically relevant variables were examined. Compared with individuals who scored low on codependency, those who obtained high scores reported significantly more family of origin difficulties and parental mental health problems, problematic intimate relationships including relationships with chemically dependent partners, and personal psychological problems including compulsivity. Contrary to prevailing theoretical predictions the high codependency group did not contain more individuals whose parents had alcohol or drug abuse problems, or a higher level of childhood physical or sexual abuse. These results suggest that co-dependency is one aspect of wider multigenerational family systems problems which are not unique to families where drug and alcohol abuse or physical and sexual abuse are major concerns.     

Subjectifying the Personality State: Theoretical Underpinnings and an Empirical Example

Recent developments in personality research highlight the value of modelling dynamic state-like manifestations of personality. The present work integrates these developments with prominent clinical models addressing within-person multiplicity and promotes the exploration of models centred on state-like manifestations of personality that function as cohesive organizational units. Such units possess distinct subjective qualities and are characterized by specific affects, behaviours, cognitions, and desires that tend to be co-activated. As background, we review both theory and research from the fields of social cognition, psychotherapy, and psychopathology that serve as the foundation for such models. We then illustrate our ideas in greater detail with one well-supported clinical model—the schema therapy mode model, chosen because it provides a finite and definite set of modes (i.e. cohesive personality states). We assessed these modes using a newly developed experience-sampling measure administered to 52 individuals (four times daily for 15 days). We estimated intraindividual and group-level temporal and contemporaneous networks based on the within-person variance as well as between-person network. We discuss findings from exemplar participants and from group-level networks and address cross-model particularities and consistencies. In conclusion, we consider potential idiographic and nomothetic applications of subjective states dynamic personality research based on intensive longitudinal methods. © 2020 European Association of Personality Psychology     

The Deceiving Mirror. Altered Body Perception and Alexithymia in a Group of Sports Adolescents and Adults

Recent literature emphasizes an altered perception of the body in subjects practicing sport to pursue an ideal body image. Sometimes such bodily misperception is associated with the inability to recognize and express emotions, and addiction to sport. This research investigates the relationship between body image and alexithymia in a group of 363 sportive adolescents and adults, including 78 males and 285 females, aged 11 to 68?years. Participants completed the Anamnestic Data Questionnaire, Body Uneasseness Test, and Toronto Alexithymia Scale (TAS-20). Results highlight differences between adolescents and adults, especially about externally oriented thinking, concern for body image, and compulsive self-monitoring.
