The global workspace theory,the phenomenal concept strategy,and the distribution of consciousness

Peter Carruthers argues that the global workspace theory implies there are no facts of the matter about animal consciousness. The argument is easily extended to other cognitive theories of consciousness, posing a general problem for consciousness studies. But the argument proves too much, for it also implies that there are no facts of the matter about human consciousness. A key assumption is that scientific theories of consciousness must explain away the explanatory gap. I criticize this assumption and point to an alternative strategy for defending scientific theories of consciousness, one that better reflects the ongoing scientific practice. I argue there are introspectable inferential connections from phenomenal concepts to functional concepts that scientists can use to individuate the global workspace in terms of capacities that animals and humans share.     

Motivation for Collective Action: Group Consciousness as Mediator of Personality, life Experiences, and Women's Rights Activism

Prior research on political activism focused on direct predictors of collective action (e.g., life experiences), with little attention paid to what psychologically motivates individuals to act. The group consciousness literature provides an obvious psychological motive for activism, but ignores individual difference variables that differentiate people who develop group consciousness from those who do not. This article integrates the two literatures on activism and group consciousness, and presents a model whereby group consciousness mediates relationships between collective action and personality and life experiences. The general model was evaluated empirically by examining feminist consciousness and women's rights activism in two samples. Feminist consciousness was found to mediate relationships between activism and anumber of personality and life experience variables, including low authoritarianism, political salience, sexual oppression, and education about women's position in society. The possible extension of this model to other kinds of political activism is discussed.     

Computation, reduction, and teleology of consciousness

This paper aims to explore mechanistic and teleological explanations of consciousness. In terms of mechanistic explanations, it critiques various existing views, especially those embodied by existing computational cognitive models. In this regard, the paper argues in favor of the explanation based on the distinction between localist (symbolic) representation and distributed representation (as formulated in the connectionist literature), which reduces the phenomenological difference to a mechanistic difference. Furthermore, to establish a teleological explanation of consciousness, the paper discusses the issue of the functional role of consciousness on the basis of the aforementioned mechanistic explanation. A proposal based on synergistic interaction between the conscious and the unconscious is advanced that encompasses various existing views concerning the functional role of consciousness. This two-step deepening explanation has some empirical support, in the form of a cognitive model and various cognitive data that it captures.     

Physiological arousal,exposure to a relatively lengthy aggressive film,and aggressive behavior

Male college students viewed either a 15-minute aggressive television program excerpt or a neutral one. Half of the students in each group were then angered or treated in a neutral fashion by a confederate. Each subject was allowed to retaliate by delivering electric shocks to the confederate as an evaluation of a problem solution he supposedly had completed. Heart rate was measured (a) before exposure to the television program, (b) after exposure to the program, (c) immediately before delivering the shock, and (d) immediately after shock delivery. Angered men who had seen the aggressive film were most aggressive toward the confederate and exhibited the lowest average pulse rates both before and after shock delivery. The findings are discussed in terms of their implication for arousal vs disinhibition conceptualizations of aggressive behaviors following exposure to television violence.     

Political Participation and Feminist Consciousness Among Women Activists of the 1960s

This paper examined the hypothesis that women who took part in student movements of the 1960s would be distinguishable from their contemporaries in terms of political ideology, political behavior, and feminism in middle age. Women who had been identified as student activists in public records during the late 1960s and early 1970s were compared to a sample of nonactivist peers. Although the two groups scored similarly on variables related to work and family arrangements, former activists scored higher on measures of leftist political orientation and political efficacy, reported greater political salience and collectivism, and reported greater current political participation. Although both groups reported high levels of feminist consciousness and identity, activists scored significantly higher. The difficulty of politically mobilizing women to combat gender discrimination is discussed in light of the discrepancy between consciousness and activism in the comparison group.     

Lost in the Sauce: The Effects of Alcohol on Mind Wandering

ABSTRACT— Alcohol consumption alters consciousness in ways that make drinking both alluring and hazardous. Recent advances in the study of consciousness using a mind-wandering paradigm permit a rigorous examination of the effects of alcohol on experiential consciousness and metaconsciousness. Fifty-four male social drinkers consumed alcohol (0.82 g/kg) or a placebo beverage and then performed a mind-wandering reading task. This task indexed both self-caught and probe-caught zone-outs to distinguish between mind wandering inside and outside of awareness. Compared with participants who drank the placebo, those who drank alcohol were significantly more likely to report that they were zoning out when probed. After this increase in mind wandering was accounted for, alcohol also lowered the probability of catching oneself zoning out. The results suggest that alcohol increases mind wandering while simultaneously reducing the likelihood of noticing one's mind wandering. Findings are discussed with regard to theories of alcohol and theories of consciousness.     

THE DUALISTIC,DISCARNATE PICTURE THAT HAUNTS THE COGNITIVE SCIENCE OF RELIGION

A dualistic, discarnate picture haunts contemporary cognitive science of religion (CSR). Cognitive scientists of religion generally assert or assume a reductive physicalism, primarily through unconscious mental mechanisms that detect supernatural agency where none exists and a larger purpose to life when none exists. Accompanying this focus is a downplaying of conscious reflection in religious belief and practice. Yet the mind side of dualism enters into CSR in interesting ways. Some cognitive scientists turn practitioners of religion into dualists who allegedly believe in disembodied spirits. By emphasizing supernatural agency, CSR neglects nonpersonal powers and meanings in religion, both in terms of magical thinking and practice and of nonpersonal conceptions of divinity. Additionally, some cognitive scientists of religion declare that all humans are innate dualists. They use this alleged dualism to explain beliefs about both an afterlife and transfers of consciousness. Finally, some call on this dualism to serve a salvific function, trying to salvage some meaning to human life.     

Characteristics of dropouts, remainers, and refusers at a psychosocial rehabilitation program for the chronically mentally disabled

Thirty-eight chronically mentally disabled patients who were invited to join a newly established, vocationally oriented, day treatment program in Raleigh, North Carolina, served as subjects. We attempted to determine whether demographic and psychosocial characteristics significantly differed among groups of clients who dropped out of, remained in, or refused membership in this community-support program. A variety of demographic, expectancy, psychological, and psychosocial measures were administered to each subject. Most significant was the finding that the subjects' perceived level of help and support from friends was a significant determinant of the level of program participation. Those subjects who refused to participate (refusers) perceived themselves as receiving proportionately less support than did members of the other two groups (dropouts and remainers).     

Against the spotlight model of consciousness

The spotlight metaphor for the characterization of consciousness is examined. It is argued that, in effect, models based on this metaphor are not explanatory. In crucial respects, the models are not informative and they can account neither for the specific qualities of human consciousness nor for its function. In the spirit of pragmatic analyses in language, it is suggested that consciousness be viewed as an act. With this, a shift is made from a selectional to a generative perspective of consciousness. The proposal is grounded in a general critique of cognitive modelling in terms of underlying mental representations.     

Stigma Consciousness and the Race Gap in College Academic Achievement

Stereotyped individuals vary in how chronically self-conscious they are of their stigmatized status, a variable called stigma consciousness. The present study examined whether stigma consciousness was negatively related to academic achievement in college for academically stigmatized (Black and Hispanic) students, but not for academically non-stigmatized (White and Asian) students. Results revealed that stigmatized students who were high in stigma consciousness had lower GPAs than stigmatized students who were low in stigma consciousness. Moreover, GPAs of stigmatized students who were low in stigma consciousness did not differ from those of non-stigmatized students. These results complement recent laboratory investigations of stigma consciousness among women and contribute to the literature on stereotype threat by extending the phenomenon to real-world academic performance.     

Transcendental meditation, mindfulness, and longevity: an experimental study with the elderly

Can direct change in state of consciousness through specific mental techniques extend human life and reverse age-related declines? To address this question, 73 residents of 8 homes for the elderly (mean age = 81 years) were randomly assigned among no treatment and 3 treatments highly similar in external structure and expectations: the Transcendental Meditation (TM) program, mindfulness training (MF) in active distinction making, or a relaxation (low mindfulness) program. A planned comparison indicated that the "restful alert" TM group improved most, followed by MF, in contrast to relaxation and no-treatment groups, on paired associate learning; 2 measures of cognitive flexibility; mental health; systolic blood pressure; and ratings of behavioral flexibility, aging, and treatment efficacy. The MF group improved most, followed by TM, on perceived control and word fluency. After 3 years, survival rate was 100% for TM and 87.5% for MF in contrast to lower rates for other groups.     

Anesthesia, neural information processing, and conscious awareness

Possible systemic effects of general anesthetic agents on neural information processing are discussed in the context of the thalamocortical suppression hypothesis presented by Drs. Alkire, Haier, and Fallon (this issue) in their PET study of the anesthetized state. Accounts of the neural requisites of consciousness fall into two broad categories. Neuronal-specificity theories postulate that activity in particular neural populations is sufficient for conscious awareness, while process-coherence theories postulate that particular organizations of neural activity are sufficient. Accounts of anesthetic narcosis, on the other hand, explain losses of consciousness in terms of neural signal-suppressions, transmission blocks, and the disruptions of signal interpretation. While signal-suppression may account for the actions of some anesthetic agents, the existence of anesthetics, such as choralose, that cause both loss of consciousness and elevated discharge rates, is problematic for a general theory of narcosis that is based purely on signal suppression and transmission-block. However, anesthetic agents also alter relative firing rates and temporal discharge patterns that may disrupt the coherence of neural signals and the functioning of the neural networks that interpret them. It is difficult at present, solely on the basis of regional brain metabolic rates, to test process-coherence hypotheses regarding organizational requisites for conscious awareness. While these pioneering PET studies have great merit as panoramic windows of mind-brain correlates, wider ranges of theory and empirical evidence need to be brought into the formulation of truly comprehensive theories of consciousness and anesthesia.     

Consciousness: mapping the theoretical landscape

What makes us conscious? Many theories that attempt to answer this question have appeared recently in the context of widespread interest about consciousness in the cognitive neurosciences. Most of these proposals are formulated in terms of the information processing conducted by the brain. In this overview, we survey and contrast these models. We first delineate several notions of consciousness, addressing what it is that the various models are attempting to explain. Next, we describe a conceptual landscape that addresses how the theories attempt to explain consciousness. We then situate each of several representative models in this landscape and indicate which aspect of consciousness they try to explain. We conclude that the search for the neural correlates of consciousness should be usefully complemented by a search for the computational correlates of consciousness.     

Consciousness as recursive, spatiotemporal self-location

At the phenomenal level, consciousness arises in a consistently coherent fashion as a singular, unified field of recursive self-awareness (subjectivity) with explicitly orientational characteristics—that of a subject located both spatially and temporally in an egocentrically-extended domain. Understanding these twin elements of consciousness begins with the recognition that ultimately (and most primitively), cognitive systems serve the biological self-regulatory regime in which they subsist. The psychological structures supporting self-located subjectivity involve an evolutionary elaboration of the two basic elements necessary for extending self-regulation into behavioral interaction with the environment: an orientative reference frame which consistently structures ongoing interaction in terms of controllable spatiotemporal parameters, and processing architecture that relates behavior to homeostatic needs via feedback. Over time, constant evolutionary pressures for energy efficiency have encouraged the emergence of anticipative feedforward processing mechanisms, and the elaboration, at the apex of the sensorimotor processing hierarchy, of self-activating, highly attenuated recursively-feedforward circuitry processing the basic orientational schema independent of external action output. As the primary reference frame of active waking cognition, this recursive self-locational schema processing generates a zone of subjective self-awareness in terms of which it feels like something to be oneself here and now. This is consciousness-as-subjectivity.     

Importance of considering background factors when evaluating the effects of compensatory education programs designed for young children

A comparison was made of the intelligence and achievement of three groups of disadvantaged Negro kindergarten children: 27 who attended a summer Headstart program, 56 who attended a year-long Prekindergarten program, and 44 who had no preschool experience. No differences were found in test scores among the groups. When the socioeconomic background of the children was investigated, it was found that although the children were correctly classified as lower class, there were differecees among them in terms of socioeconomic status, and these differences were related to their test scores. The results suggest that the common practice of grouping all disadvantaged children in one category (lower class) may mask differences that may have an important effect on the children's ability to benefit from compensatory education programs. This may make it difficult to determine whether compensatory education has been effective.     

Eliciting Change in Maltreating Fathers: Goals, Processes, and Desired Outcomes

There has been a growing recognition of the need to provide appropriate intervention services to fathers who have been abusive in their families. This paper highlights four specific treatment goals for fathers who maltreat their children, along with therapeutic strategies necessary to accomplish desired outcomes. These goals were developed as part of the Caring Dads: Helping Fathers Value Their Children program and include: (a) developing sufficient trust and motivation to engage men in the process of examining their fathering; (b) increasing men's awareness and application of child-centered fathering; (c) increasing men's awareness of, and responsibility for, abusive and neglectful fathering, including domestic violence; and (d) rebuilding trust with their children and planning for the future. The strategies include a range of approaches, such as motivational interviewing, psychoeducation, cognitive-behavioral techniques, confrontation, and shame work. We describe each goal in terms of desired outcomes and primary therapeutic techniques used by the facilitators, and illustrate each with examples of exercises from the Caring Dads program. Implications for the training of therapists working with maltreating fathers are also highlighted.     

Transcendence and psychological health: studies with long-term participants of the transcendental meditation and TM-Sidhi program

We investigated the nature of the relationship between experiences of transcendental consciousness and psychological health. In Study 1, three groups with different levels of experience in transcendental meditation (TM) and in the TM-Sidhi program (techniques that have been shown to produce experiences of transcendental consciousness) were studied, using the self-investigation method of Hermans (1976). We employed blind interviewers and raters with various attitudes toward TM to minimize the possible impact of a variety of artifacts. Cross-sectionally, experience with TM and the TM-Sidhi program was positively related to a general measure of psychological health (p = .002); longitudinally, the meditating groups improved more than the control group on the psychological health measure (p less than .03). In Study 2, two contrast groups of long-term participants were similar on several confounding variables but differed on physiological indicators of experiences of transcendental consciousness. The groups with the positive physiological indicators showed a trend toward higher scores on the psychological health factor (p = .092), indicating that psychological health may be developed through the systematic cultivation of transcendental meditation and the TM-Sidhi program.
