Drawing the boundary between subject and object: Comments on the mind-brain problem

Physics says that it cannot deal with the mind-brain problem, because it does not deal in subjectivities, and mind is subjective. However, biologists (among others) still claim to seek a material basis for subjective mental processes, which would thereby render them objective. Something is clearly wrong here. I claim that what is wrong is the adoption of too narrow a view of what constitutes ‘objectivity’, especially in identifying it with what a ‘machine’ can do. I approach the problem in the light of two cognate circumstances: (a) the ‘measurement problem’ in quantum physics, and (b) the objectivity of standard mathematics, even though most of it is beyond the reach of ‘machines’. I argue that the only resolution to such problems is in the recognition that closed loops of causation are ‘objective’; i.e. legitimate objects of scientific scrutiny. These are explicitly forbidden in any machine or mechanism. A material system which contains such loops is called ‘complex’. Such complex systems thus must possess nonsimulable models; i.e. models which contain impredicativities or ‘self-references’ which cannot be removed, or faithfully mapped into a single coherent syntactic time-frame. I consider a few of the consequences of the above, in the context of thus redrawing the boundary between subject and object.     

The role of spatial frequency in the processing of hierarchically organized stimuli

Can spatial frequency differences between local and global forms account for differences in the way different levels of structure are analyzed? We examined this question by having subjects identify local or global forms of hierarchical stimuli that had beencontrast balanced. Contrast balancing eliminates low spatial frequencies, so that both local and global forms must be identified on the basis of high spatial frequency information. Response times (RTs) to global (but not local) forms were slowed for contrast-balanced stimuli, suggesting that low spatial frequencies mediate the global RT advantage typically found. In contrast, interference between local and global forms was little affected by contrast balancing or by shifts of attention between local and global forms, suggesting that it does not result from inhibitory interactions between spatial frequency channels or from temporal precedence of low versus high spatial frequency information. Finally, shifts of attention between local and global forms were also little affected by contrast balancing, suggesting that they were not based on spatial frequency.     

Stressors, Stress Mediators, and Emotional Weil-Being Among Spouses of Soldiers Deployed to the Persian Gulf During Operation Desert Shield/Storm

The Family Factors Field Study of Operation Desert Shield/Storm (ODS) was designed to collect data on the impact of the Persian Gulf deployment on soldier/family well-being, and the effectiveness of Army and community resources in assisting and supporting families of deployed soldiers. In October 1990, a task force was assembled, and multi-agency research teams visited several Army installations. Informal individual and group interviews were conducted with spouses, unit family support leaders, unit rear detachment personnel, garrison leaders, and local Army program/service providers. The questions were aimed at identifying key stressors which spouses and children experienced in relation to the sudden deployment, as well a stress mediators such as social supports and personal coping skills. Anecdotal information collected during the site visits, combined with findings from previous research on Army families, was used to develop a questionnaire designed to quantify those variables which emerged as relevant to a study of stressors and stress mediators in the context of the ODS deployment.     

The Psychophysiology of Sensation Seeking

This article summarizes studies relating the trait of sensation seeking to electrodermal and heart-rate responses and cortical evoked potential arousal. Stimulus factors of novelty, intensity, and stimulus significance are important. High sensation seekers tend to give stronger physiological orienting responses than lows to novel stimuli of moderate intensity, particularly when such stimuli are of specific interest. Lows tend to show defensive responses as defined by heart-rate acceleration. The cortical reaction of the highs tends to be augmented by intense visual or auditory stimuli, while that of the lows tends to be reduced or unresponsive to variations in stimulus intensity. Differences between psychophysiological responses of high and low sensation seekers are interpreted as reflective of different evolved biological strategies for processing novel or intense stimulation.     

Interpersonal loss and self-mutilation

Self-mutilation was hypothesized to increase in frequency during periods of interpersonal loss in a treatment program for seriously disturbed adolescents. The study examined changes in the frequency of acts of self-mutilation, aggression, and running away for 32 teenagers who experienced interpersonal loss when staff members left employment. Data were collected for a 4-year period. Statistical findings indicated that the frequency of self-mutilation increased significantly during the time period of anticipated loss, 2 weeks prior to staff terminations. There was no significant increase in the frequency of self-mutilation immediately following the staff terminations. Also, there was no significant change in the rates of aggression or running away either before or after the loss events. It was concluded that the time of anticipated loss was the period of highest risk for these adolescents in terms of self-mutilative behavior.     

SEEING TWO AS ONE:

Abstract -Object tokens are episodic visual representations that mediate the ability to track visual events as they move about and change over time. Multiple tokens also allow the viewer to individuate multiple instances of a single type of object. In the present study, we established a functional link for object tokens in two seemingly disparate visual phenomena: apparent motion and repetition blindness [RB]. In RB, repeated items are more difficult to perceive than unre-peated items. Using displays in which two sets of alphanumeric characters streamed in opposite directions across a computer screen in apparent motion, we found increased RB for targets appearing within a single apparent motion stream, relative to targets in different apparent motion streams. The results are inconsistent with refractory period or memory retrieval accounts of RB and support the role of object tokens in both apparent motion and RB.     

Process characteristics of worry and obsessive intrusive thoughts

One hundred and twenty-five university students were administered a battery of self-report measures to assess worry disposition and content, frequency of obsessive intrusive thoughts, and 10 conceptually derived appraisal dimensions of worry and obsessional intrusions. Process ratings indicated that the worrisome thoughts were considered more disturbing than the ego-dystonic intrusive thoughts. Worry was also distinguished by a focus on the possible consequences of negative events, whereas concern about the personal meaning of the thought was a unique process dimension for obsessive intrusive thoughts. Both content and process variables are important in differentiating worry and obsessive-like intrusive thoughts in a nonclinical population.     

Burnout in Spurned Medical Caregivers and the Impact of Job Expectancy Training

This study represents an extrapolation to the practical realm of a theoretical model that has been supported thus far only by laboratory studies. The model regards the rejection of help by people in need as being stressful for caregivers partly because it violates their expectations of acceptance and threatens their self-image as competent caregivers. It was hypothesized that high levels of perceived rejection by patients and others at work would contribute to burnout in medical caregivers. It was also predicted that high levels of stress preparation in caregivers' training with regard to job expectancies and patient (non)compliance would lessen burnout and buffer the effects of spurning. Responses to a questionnaire by a sample of physicians and hospital nurses revealed a direct association of perceived spurning, as well as an inverse association of stress preparation with burnout, and gave some indication of buffering, as hypothesized. Expressions of violated expectancies and of job disillusionment were directly associated with burnout and inversely associated with stress preparation. Informal job expectancy shaped by coworkers was found to be directly associated with burnout in physicians, but it was inversely associated with burn out in nurses. The implications of these findings are considered     

On seeing oneself as “left out”: The chronically complaining patient in psychotherapy

A clinical observation regarding patients who complain about feeling left out and/or second best provides the framework for this paper. What is expressed is a form of separation anxiety coupled with a loser self-concept. It is suggested that these patients represent a milder form of the moral masochism. Early theoretical formulations include Freud and his emphasis on the superego and Reich's emphasis on the masochist's fear of being left alone. Kramer's little man phenomenon is an example of a more current theoretical formulation which takes account of the complexities of the ego, and composite self and identity in the clinical phenomena observed. A case of a latency-aged child is provided.     

An External Validation of Laboratory Evidence for Earned Dignity

Both theoretical arguments and laboratory evidence indicate that society awards earned dignity (worth) to persons perceived as voluntarily performing praiseworthy behaviors. Laboratory research, as well as common observation, indicates also that society accords an intrinsic dignity unconditionally to all people. On a questionnaire given in class, college students reported increased dignity earned by the Russians from their praiseworthy (i.e., embracing freedom) and voluntary rejection of the attempted coup in 1991. The questionnaire also revealed a general belief in intrinsic dignity. External evidence for earned dignity is shown by increased international support for the Russians after rejection of the coup. This convergence of laboratory and external data validates the laboratory techniques for studying social perception of human dignity.
