Fear of Anxiety in Fearful Adults: An Analysis of Heterogeneity Among Phobia Types

Fear of anxiety, the fear of developing physiological symptoms associated with anxiety, is investigated in this study and the extent to which fear of anxiety is differentially present in the various subtypes of specific phobias. Participants were 260 undergraduate students divided into those having fears corresponding to one of the specific phobia types and those having no reported fears. Participants completed a variety of measures including the Agoraphobic Cognitions Questionnaire and the Body Sensations Questionnaire. Results indicated fearful participants had more fear of anxiety than non-fearful participants. In addition, non-fearful participants reported significantly less frequent catastrophic cognitions than fearful participants of the situational and other types. Non-fearful control participants also reported less fear of bodily sensations than fearful participants of the animal and other subtypes. This study provides supporting evidence that the phenomenon of fear of anxiety is present in fears similar to specific phobias.     

Emotion Regulation and Stress

This paper examines the similarities and differences between emotion regulation and stress coping and reviews research that suggests that the association between emotion regulation and stress may be explained by the common neural structures. Developmental changes related to emotion regulation and stress are also discussed. Overall, the research suggests that individuals vary in their ability to regulate emotions and cope with stress, and these abilities may differ across age. Little is known, however, about the factors that influence individual differences in emotion regulation and stress coping. We suggest that behavioral genetic designs may be an important avenue for future research. Such research would indicate the extent to which variation in emotion regulation and stress are due to genetic and/or environmental influences and further the extent to which common genetic and/or environmental factors explain the links between emotion regulation and stress.     

Anticipatory attention during the sleep onset period

To examine whether anticipatory attention or expectancy is a cognitive process that is automatic or requires conscious control, we employed a paired-stimulus event-related potential (ERP) paradigm during the transition to sleep. The slow negative ERP wave observed between two successive stimuli, the Contingent Negative Variation (CNV), reflects attention and expectancy to the second stimulus. Thirteen good sleepers were instructed to respond to the second stimulus in a pair during waking sessions. In a non-response paradigm modified for sleep, participants then fell asleep while tones played. As expected, N1 decreased and P2 increased in amplitude systematically with the loss of consciousness at sleep onset; the CNV was increasingly more positive. Sleep onset latency was correlated with the amplitude of the CNV. The systematic attenuation of the CNV waveform at sleep onset and its absence in sleep indicates that anticipatory attention requires endogenous conscious control.     

Measuring multiple minority stress: the LGBT People of Color Microaggressions Scale

Lesbian, gay, and bisexual individuals who are also racial/ethnic minorities (LGBT-POC) are a multiply marginalized population subject to microaggressions associated with both racism and heterosexism. To date, research on this population has been hampered by the lack of a measurement tool to assess the unique experiences associated with the intersection of these oppressions. To address this gap in the literature, we conducted a three-phase, mixed method empirical study to assess microaggressions among LGBT-POC. The LGBT People of Color Microaggressions Scale is an 18-item self-report scale assessing the unique types of microaggressions experienced by ethnic minority LGBT adults. The measure includes three subscales: (a) Racism in LGBT communities, (b) Heterosexism in Racial/Ethnic Minority Communities, and (c) Racism in Dating and Close Relationships, that are theoretically consistent with prior literature on racial/ethnic minority LGBTs and have strong psychometric properties including internal consistency and construct validity in terms of correlations with measures of psychological distress and LGBT-identity variables. Men scored higher on the LGBT-PCMS than women, lesbians and gay men scored higher than bisexual women and men, and Asian Americans scored higher than African Americans and Latina/os.     

Tracking and capture of constant and varying velocity stimuli: a cross-species comparison of pigeons and humans

The mechanisms underlying tracking and capture of moving objects in non-human animals are poorly understood. This set of experiments sought to further explore aspects of anticipatory tracking in pigeons and to conduct comparisons with human participants. In Experiment 1a, pigeons were presented with two types of varying velocities (fast-slow-fast or slow-fast-slow) in separate phases. They were readily able to track and anticipate both of these motion types. To examine the effects of predictability on anticipatory tracking, Experiment 1b presented the pigeons with the same two varying velocities randomly intermixed within a session. This resulted in reduced capture success, later capture, and errors that no longer anticipated ahead of the motion, suggesting that the anticipatory mechanism had been disrupted. This implies that the mechanisms involved in pigeon tracking are different from the predictive extrapolation mechanism proposed in humans. Experiment 2 tested this by presenting adult humans with a tracking task that was similar to tasks previously received by the pigeons. The capture behavior of humans was similar to the pigeons, but the errors revealed different processes underlying their tracking behavior.     

Semantic Capacities of the Right Hemisphere as Seen in Two Cases of Pure Word Blindness

Two patients with pure alexia were studied with tachistoscopically presented stimuli to examine factors influencing their ability to distinguish words from nonwords and to derive semantic information at exposures too brief for explicit letter identification. Both patients had profound right hemianopia and computerized tomography (CT) evidence of splenial destruction. Both patients were successful in making word/nonword decisions for high-frequency, but not low-frequency, words. They could judge semantic class membership reliably for such common categories as animals and vegetables, but not for arbitrarily selected categories, such as office-related items. Judgments about the gender of people's names and place versus person name distinctions were made with high reliability. Results are interpreted as evidence for limited word recognition and semantic-processing capacity in the right hemisphere.     

Concordance Between Parent Reports of Children's Mental Health Services and Service Records: The Services Assessment for Children and Adolescents (SACA)

The concordance between parent reports of children's mental health services and medical and administrative service records were assessed in a field test of the Services Assessment for Children and Adolescents (SACA) interview instrument. Service use reports from primary caregivers, usually mothers, for their child's emotional or behavioral problems were compared against inpatient, outpatient, and school records in St. Louis, one of the pilot sites for the Multi-Site Study of Service Use, Need, Outcomes and Costs in Child and Adolescent Populations (UNOCCAP). A global any use service variable, comprised of inpatient, outpatient, and school reports, yielded an overall service use concordance kappa of .76 between parent reports and records. Parent reports of inpatient hospitalization services using the SACA yielded the highest agreement with medical records, with kappa statistics of 1.00 for use of any inpatient hospital care and for medication use. Parent reports of specific inpatient services concurred with medical records more moderately, yielding kappas from .50 to .66. Reports of any outpatient mental health services yielded variable rates of agreement, with kappas ranging from .67 for any use of outpatient care, to .66 for medication use, to negligible kappas for specific treatments. Parent reports of school services were weakly related to records for most services, except for moderate agreement (.48) on placement in special classrooms for emotional or behavioral problems. Family burden or impact discriminated more powerfully than other variables between respondents who concurred with records and those who did not.     

Self-Editing: On the Relation Between behavioral and Psycholinguistic Approaches

In Skinner's (1957) conceptual analysis, the process of self-editing is integral to the dynamic complexities of multiply determined verbal behavior, but the analysis has generated little in the way of an experimental analysis. The majority of scientific work on self-editing has taken place within linguistics and cognitive psycholinguistics. Here we compare and contrast behavioral and cognitive psycholinguistic approaches to self-editing, highlighting points of contact that can be identified despite fundamental differences in theoretical styles. We conclude that the two approaches are not mutually exclusive on all dimensions, and suggest that a consideration of cognitive psycholinguistic research may help to spur an experimental analysis of self-editing from a behavioral perspective.     

A fresh look at an ancient receptor family: emerging roles for low density lipoprotein receptors in synaptic plasticity and memory formation

The well-known family of low-density lipoprotein receptors represents a collection of ancient membrane receptors that have been remarkably conserved throughout evolution. These multifunctional receptors, known to regulate cholesterol transport, are becoming increasingly interesting to the neuroscience community due to their ability to transduce a diversity of extracellular signals across the membrane in the adult CNS. Their roles in modulating synaptic plasticity and necessity in hippocampus-specific learning and memory have recently come to light. In addition, genetic, biochemical and behavioral studies have implicated these signaling systems in a number of human neurodegenerative and neuropsychiatric disorders involving loss of cognitive ability, such as Alzheimer's disease, schizophrenia and autism. This review describes the known functions of these receptors and discusses their potential role in processes of synaptic regulation and memory formation.     

The application of mindfulness-based cognitive interventions in the treatment of co-occurring addictive and mood disorders

This article reviews the theory, clinical application, and empirical findings on mindfulness-based cognitive therapy (MBCT) for mental health and addictive disorders. Expanding upon the research demonstrating the efficacy of cognitive-behavioral therapy (CBT) for addiction, this article develops and explores the rationale for combining mindfulness-based interventions with evidence-based CBTs in treating addictive disorders, with an emphasis on substance use disorders with co-occurring mood disorders. This article proposes that deficits in affect--regulation related to the behavioral and emotional effects of neurobiological changes that occur with long-term substance abuse--pose a unique set of challenges in early recovery. Prolonged use of addictive substances impairs the brain pathways that mediate certain affect regulation functions. These functions involve attention and inhibitory control, the saliency of and response to addictive versus natural reward stimuli, and the ability to detach or maintain perspective in response to strong emotional states. In treating this affective dysregulation, which can contribute to the vulnerability to relapse in the early stages of recovery, the affect-regulation-specific focus of MBCT adds a valuable element to augment CBT for addiction. Summarizing magnetic resonance imaging and positron emission tomography findings on the effects of MBCT and the neurobiology of drug addiction, this article outlines directions for further research on potential benefits of MBCT for the recovering individual. Finally, this article describes a structured protocol, developed at the Mount Sinai School of Medicine in New York City, which combines CBT with mindfulness-based intervention, for the treatment of affect-regulation issues specific to co-occurring addictive and mood disorders.
