Consciousness and the self-sensing brain: implications for feeling and meaning

A number of authors have proposed or alluded to the significance for consciousness of sensing within the brain. This article reviews some of these proposals along with questions that have been raised and argues that consciousness might be understood as a property of a system that functions as a sense in the biological meaning of that term. The sense of consciousness is conceived not as a fixed structure but rather as a structure with variations, consistent with contemporary notions of complexity theory. A sense of consciousness has implications for concepts central to an understanding of consciousness, most notably the concepts of feeling and meaning. William James and others have proposed feeling as a ubiquitous aspect of consciousness. The concept of sensing, like that of feeling, provides a bridge between the organic and phenomenological aspects of consciousness, and the rudiments of meaning can be seen in the symbolizing role of a sense as it relates to adaptive problem solving.     

Ghosts of paradigms past: the once and future evolution of psychoanalytic thought

An example of the psychoanalytic mode of thought is put forward concerning how psychoanalytic theories have historically been constituted and transformed. The model of world hypotheses, characterized by multiple irresolvable truth claims, captures the nature of most psychoanalytic theorizing until about 1970. Each of two world hypotheses--one grounded in intrapsychic conflict (seen when the analyst observes from outside the transference) and the other in interpersonal internalization (seen when the analyst observes from inside the bidirectional interactive processes)--is an autonomous and self-sufficient aggregate. The stance taken by the analyst-observer with respect to the analytic interaction is key to seeing how the two world hypotheses are made manifest in clinical work and in theory. By contrast, the model of competing programs captures the essential nature of most psychoanalytic theorizing since about 1970, and is characterized by the necessity of each progressively evolving through a particular kind of commerce with its neighbors. Such commerce is necessary when a program is in danger of degenerating. In this way of thinking, there is a fundamental tension between classical psychoanalysis adapting to the demands and exigencies of its particular and ever evolving historical niche and simultaneously retaining the core commitments that guarantee continuity. Honoring the forces of progression displaces the quest for truth as a paramount goal of psychoanalysis. A developmental lag in recognizing this transformation has hindered progress toward a comparative, process-centered psychoanalysis.     

The facets of anxiety sensitivity represented in the childhood anxiety sensitivity index: confirmatory analyses of factor models from past studies

Results of past factor analytic studies of the Childhood Anxiety Sensitivity Index and Anxiety Sensitivity Index were used to formulate hypotheses about factor models of anxiety sensitivity. Using a nonclinical sample of 767 children and adolescents and confirmatory factor analysis, hypothesized models with 2, 3, and 4 lower order factors (facets) were tested. Goodness-of-fit criteria indicated that a model with 4 facets fits these data well. Support was found for factorial invariance of the 4 facets across age and gender, using nonclinical and clinical samples. Results support a hierarchical factor model in that there was a strong general factor, explaining 71% of the variance. Findings are discussed in the context of anxiety sensitivity theory and research with children and adolescents.     

The influence of ethnic discrimination and ethnic identification on African American adolescents' school and socioemotional adjustment

Abstract Do experiences with racial discrimination at school predict changes in African American adolescents' academic and psy‐chological functioning? Does African American ethnic identity buffer these relations? This paper addresses these two questions using two waves of data from a longitudinal study of an economically diverse sample of African American adolescents living in and near a major East Coast metropolis. The data were collected at the beginning of the 7th grade and after the completion of the 8th grade. As expected, experiences of racial discrimination at school from one's teachers and peers predicts declines in grades, academic ability self‐concepts, academic task values, mental health (increases in depression and anger, decreases in self‐esteem and psychological resiliency), and increases in the proportion of one's friends who are not interested in school and who have problem behaviors. A strong, positive connection to one's ethnic group (our measure of ethnic identity) reduced the magnitude of the association of racial discrimination experiences with declines in academic self‐concepts, school achievement, and perception of friends' positive characteristics, as well as the association of the racial discrimination experiences with increases in problem behaviors.     

Disfluencies signal theee,um, new information

Speakers are often disfluent, for example, saying theee uh candle instead of the candle. Production data show that disfluencies occur more often during references to things that are discourse-new, rather than given. An eyetracking experiment shows that this correlation between disfluency and discourse status affects speech comprehension. Subjects viewed scenes containing four objects, including two cohort competitors (e.g., camel, candle), and followed spoken instructions to move the objects. The first instruction established one cohort as discourse-given; the other was discourse-new. The second instruction was either fluent or disfluent, and referred to either the given or new cohort. Fluent instructions led to more initial fixations on the given cohort object (replicating Dahan et al., 2002). By contrast, disfluent instructions resulted in more fixations on the new cohort. This shows that discourse-new information can be accessible under some circumstances. More generally, it suggests that disfluency affects core language comprehension processes.     

Desensitization of postsynaptic glutamate receptors contributes to high-frequency homosynaptic depression of aplysia sensorimotor connections

Withdrawal reflexes of Aplysia are mediated in part by a monosynaptic circuit of sensory (SN) and motor (MN) neurons. A brief high-frequency burst of spikes in the SN produces excitatory postsynaptic potentials (EPSPs) that rapidly decrease in amplitude during the burst of activity. It is generally believed that this and other (i.e., low-frequency) forms of homosynaptic depression are entirely caused by presynaptic mechanisms (e.g., depletion of releasable transmitter). The present study examines the contribution that desensitization of postsynaptic glutamate receptors makes to homosynaptic depression. Bath application of cyclothiazide, an agent that reduces desensitization of non-NMDA glutamate receptors, reduced high-, but not low-frequency synaptic depression. Thus, a postsynaptic mechanism, desensitization of glutamate receptors, can also contribute to homosynaptic depression of sensorimotor synapses.     

Predicting the suicide attempts of lesbian, gay, and bisexual youth

In this study predictors of serious suicide attempts among lesbian, gay, and bisexual (LGB) youth were examined. Three groups were compared: youth who reported no attempts, youth who reported attempts unrelated to their sexual orientation, and youth whose attempts were considered related to their sexual orientation. About one third of respondents reported at least one suicide attempt; however, only half of the attempts were judged serious based on potential lethality. About half of all attempts were related to youths' sexual orientation. Factors that differentiated youth reporting suicide attempts and those not reporting attempts were greater childhood parental psychological abuse and more childhood gender-atypical behavior. Gay-related suicide attempts were associated with identifiability as LGB, especially by parents. Early openness about sexual orientation, being considered gender atypical in childhood by parents, and parental efforts to discourage gender atypical behavior were associated with gay-related suicide attempts, especially for males. Assessment of past parental psychological abuse, parental reactions to childhood gender atypical behavior, youths' openness about sexual orientation with family members, and lifetime gay-related verbal abuse can assist in the prediction of suicide attempts in this population.     

I wish the hour were over: elements of a moral dilemma

In contrast to the viewpoint that sees conflict as deriving from defense against instinctual drives and thus as an intrapsychic phenomenon, this essay presents conflict as sometimes being an external opposition between disparate configurations of the self. These parallel sectors with different goals and ambitions can be seen in a continuum from the dramatic narcissistic behavior disorders to more subtle instances of moral dilemmas. A clinical illustration is offered to demonstrate its occurrence and management in psychoanalysis.     

The academic achievement of African American students during early adolescence: an examination of multiple risk,promotive, and protective factors

This study examined the effects of multiple risk, promotive, and protective factors on three achievement-related measures (i.e., grade point average, number of absences, and math achievement test scores) for African American 7th-grade students (n = 837). There were 3 main findings. First, adolescents had lower grade point averages, more absences, and lower achievement test scores as their exposure to risk factors increased. Second, different promotive and protective factors emerged as significant contributors depending on the nature of the achievement-related outcome that was being assessed. Third, protective factors were identified whose effects were magnified in the presence of multiple risks. Results were discussed in light of the developmental tasks facing adolescents and the contexts in which youth exposed to multiple risks and their families live.
