RATIONALE: Abnormal amygdala and frontocortical responses to emotional stimuli are implicated in bipolar disorder (BD) and have been proposed as potential treatment targets.
OBJECTIVES: The aim of this study was to investigate amygdala and frontocortical responses to emotional face stimuli in BD and the influences of mood-stabilizing medications on these responses.
METHODS: Functional magnetic resonance imaging was performed while 17 BD participants (5 unmedicated) and 17 healthy comparison (HC) participants viewed faces with happy, sad, fearful, or neutral expressions.
RESULTS: The group by stimulus-condition interaction was significant (p<0.01) for amygdala activation, with the greatest effects in the happy face condition. Relative to HC, amygdala increases were greater in unmedicated BD, but lower in medicated BD. Rostral anterior cingulate (rAC) activation was decreased in unmedicated BD compared to HC; however, BD participants taking medication demonstrated rAC activation similar to HC participants.
CONCLUSIONS: Although the sample sizes were small, these preliminary results suggest that …

Levels Of Consciousness, Archetypal Energies, And Earth Lessons: An Emerging Worldview, Carroy U. Ferguson
Carroy U "Cuf" Ferguson, Ph.D.
Worldviews emerge from our individual and collective Levels of Consciousness at given points in time and space and from what we come to “believe” is possible or not. In my own experience, my research on Consciousness, and my study of various cultures, societies, and Consciousness literature, I have identified at least seven Levels of Consciousness, twenty-five Archetypal Energies, and various Earth Lessons, which we seem to commonly experience as human beings, in our own unique personal, societal, and global life spaces.

Using fMRI, we investigated the functional organization of prefrontal cortex (PFC) as participants briefly thought of a single just-experienced item (i.e., refreshed an active representation). The results of six studies, and a meta-analysis including previous studies, identified regions in left dorsolateral, anterior, and ventrolateral PFC associated in varying degrees with refreshing different types of information (visual and auditory words, drawings, patterns, people, places, or locations). In addition, activity increased in anterior cingulate with selection demands and in orbitofrontal cortex when a nonselected item was emotionally salient, consistent with a role for these areas in cognitive control (e.g., overcoming "mental rubbernecking"). …

Objective: Existing evidence from anxiety disorder research indicates that social phobics (SP) with avoidant personality disorder (AVPD) experience more anxiety and show more impairment than patients with SP alone. The purpose of this study was to examine whether in patients diagnosed with AVPD, the co-occurrence of SP adds to its severity. We hypothesized that the addition of SP will not add to the severity of AVPD alone.
Method: Two groups of patients (AVPD = 224; AVPD/SP = 101) were compared at baseline and 2 years later on multiple demographic and clinical variables.
Results: Patients with AVPD and an additional diagnosis …

Deep encoding, relative to shallow encoding, has been shown to increase the probability of false memories in the Deese/Roediger-McDermott (DRM) paradigm (Thapar & McDermott, 2001; Toglia, Neuschatz, & Goodwin, 1999). In two experiments, we showed important limitations on the generalizability of this phenomenon; these limitations are clearly predicted by existing theories regarding the mechanisms underlying such false memories (e.g., Roediger, Watson, McDermott, & Gallo, 2001). Specifically, asking subjects to attend to phonological relations among lists of phonologically associated words (e.g.,weep, steep, etc.) increased the likelihood of false recall (Experiment 1) and false recognition (Experiment 2) of a related, nonpresented associate …
Importance Of Perceptual Representation In The Visual Control Of Action, Jack M. Loomis, Andrew C. Beall, Jonathan W. Kelly, Kristen L. Macuga
Importance Of Perceptual Representation In The Visual Control Of Action, Jack M. Loomis, Andrew C. Beall, Jonathan W. Kelly, Kristen L. Macuga

In recent years, many experiments have demonstrated that optic flow is sufficient for visually controlled action, with the suggestion that perceptual representations of 3-D space are superfluous. In contrast, recent research in our lab indicates that some visually controlled actions, including some thought to be based on optic flow, are indeed mediated by perceptual representations. For example, we have demonstrated that people are able to perform complex spatial behaviors, like walking, driving, and object interception, in virtual environments which are rendered visible solely by cyclopean stimulation (random-dot cinematograms). In such situations, the absence of any retinal optic flow that is …
Embracing Segregation: The Jurisprudence Of Choice And Diversity In Race And Sex Separatism In Schools, Nancy Levit
Embracing Segregation: The Jurisprudence Of Choice And Diversity In Race And Sex Separatism In Schools, Nancy Levit
Nancy Levit
Fifty years after Brown v. Board of Education, segregation based on race and sex is sweeping the nation's educational systems. Courts are rapidly dismantling desegregation orders, and when those desegregation orders end, school districts racially resegregate. At precisely the same time this end to racial desegregation is occurring, the government is beginning to sponsor sex segregation in schools as well. The No Child Left Behind Act provides over $400 million in federal funds for experiments in education, such as single-sex schools and classes. Embracing Segregation draws connections between the end of racial desegregation and the beginning of government-sponsored sex segregation …
Review Of Sweet Dreams: Philosophical Obstacles To A Science Of Consciousness, Leslie Marsh
Review Of Sweet Dreams: Philosophical Obstacles To A Science Of Consciousness, Leslie Marsh
Leslie Marsh
The question of how a physical system gives rise to the phenomenal or experiential (olfactory, visual, somatosensitive, gestatory and auditory), is considered the most intractable of scientific and philosophical puzzles. Though this question has dominated the philosophy of mind over the last quarter century, it articulates a version of the age-old mind–body problem. The most famous response, Cartesian dualism, is on Daniel Dennett’s view still a corrosively residual and redundant feature of popular (and academic) thinking on these matters. Fifteen years on from his anti-Cartesian theory of consciousness (Consciousness Explained, 1991), Dennett’s frustration with this tradition is still palpable. This …

More Than Meets The Eye: Investigating Imagery Type, Direction, And Outcome, Sanna Nordin, Jennifer Cumming

The effects of imagery direction on self-efficacy and performance in a dart throwing task were examined. Two imagery types were investigated: skill-based cognitive specific (CS) and confidence-based motivational general-mastery (MG-M). Seventy-five novice dart throwers were randomly allocated to one of three conditions: (a) facilitative imagery, (b) debilitative imagery, or (c) control. After 2 imagery interventions, the debilitative imagery group rated their self-efficacy significantly lower than the facilitative group and performed significantly worse than either the facilitative group or the control group. Efficacy ratings remained constant across trials for the facilitative group, but decreased significantly for both the control group and …
Professional Dancers Describe Their Imagery: Where, When, What, Why, And How, Sanna M. Nordin, Jennifer Cumming
Professional Dancers Describe Their Imagery: Where, When, What, Why, And How, Sanna M. Nordin, Jennifer Cumming
Jennifer Cumming
In-depth semistructured interviews were conducted with 14 male and female professional dancers from several dance forms. Interviews were primarily based in the 4 Ws framework (Munroe, Giacobbi, Jr., Hall, & Weinberg, 2000), which meant exploring Where, When, Why, and What dancers image. A dimension describing How the dancers employed imagery also emerged. What refers to imagery content, and emerged from two categories: Imagery Types and Imagery Characteristics. Why represents the reason an image is employed and emerged from five categories: Cognitive Reasons, Motivational Reasons, Artistic Reasons, Healing Reasons, and No reason – Triggered Imagery. There were also large individual differences …
