Test-retest reliability of component process variables within the Hopkins Verbal Learning Test-Revised

Emerging data support the construct validity of component process variables of learning and memory within the Hopkins Verbal Learning Test-Revised (HVLT-R; Brandt & Benedict, 2001); however, the test-retest reliabilities of such measures are heretofore largely unknown. This study reveals generally modest-to-low 1-year test-retest stability for several key HVLT-R component process variables (e.g., semantic clustering) in 41 healthy, younger adults. These findings are discussed in relation to issues of clinical practice and research design in neuropsychological assessment.     

Toward a phenomenology of feelings

Our understanding of emotion cannot be complete without an understanding of feelings, the experiential aspect of emotion. Despite their importance, little effort has been devoted to the careful apprehension of feelings. Based on our apprehension of many randomly selected moments of pristine inner experience, we present a preliminary phenomenology of feelings. We begin by observing that often feelings occur as directly experienced phenomena of awareness; however, often no feelings are present in experience, or if they are present, they are too faint to be observed by a process intended to observe them. Feelings range from vague to distinct and sometimes do, but other times do not, include bodily sensations. When bodily sensations are present, there is a wide range of clarity and location of these sensations. Sometimes people experience multiple distinct feelings and sometimes people experience one feeling that is a mix or blend of different feelings. We also discuss what feelings are not, including instances when feelings do not appear to be present, despite evidence suggesting the presence of underlying emotional processes (e.g., behavioral evidence of emotion). These instances of emotion but not feeling lead us to speculate that experiencing feelings is a skill developed over time through an interaction of interpersonal and intrapersonal events.

An Analysis of Natural Mentoring Relationship Profiles and Associations with Mentees’ Mental Health: Considering Links via Support from Important Others

We explored associations between natural mentoring relationship profiles and young adults’ life satisfaction and symptoms of depression via participants’ perceived support from important others accounting for participants’ perceived support and mental health prior to the onset of their natural mentoring relationships. Participants included 396 young adults (57 % female; mean age = 30.97, SD = .6), the majority of whom identified as Black or African American (79 % Black, 18 % White, 3 % Biracial). Most participants had completed high school but few participants (13 %) had completed degrees from 4 year institutions. We used a latent profile approach to identify natural mentoring relationship profiles and employed structural equation modeling to test our study hypotheses. Slightly over half of study participants (53 %) reported the presence of a natural mentor in their lives since the age of 14. Results suggest that natural mentoring relationships characterized by high levels of relational closeness and either extended relationship duration or frequent contact may promote improvements in psychological well-being among mentees over time via greater experiences of social support from important others.     

Natural Mentors, Mental Health, and Risk Behaviors: A Longitudinal Analysis of African American Adolescents Transitioning into Adulthood

Patterns of substance use are examined in a sample of over 1,200 youth in a non-metropolitan region of New England. Self-reported history and frequency of alcohol, tobacco, marijuana, inhalants, pain medications, and other hard drug use was assessed for 9th and 10th grade students. Latent class analyses identified four patterns of substance use: non-users (22%), alcohol experimenters (38%), occasional polysubstance users (29%), and frequent polysubstance users (10%). Contextual risk and protective factors in the individual, family, peer, and community domains predicted substance use patterns. Youth report of peer substance use had the largest effects on substance use class membership. Other individual characteristics (e.g., gender, antisocial behavior, academic performance, perceived harm from use), family characteristics (e.g., parental drinking, parental disapproval of youth use), and community characteristics (e.g., availability of substances) demonstrated consistent effects on substance use classes. Implications for prevention are discussed from a social-ecological perspective.     

Finding the Lost Girls: Multiplicity and Dissociation in the Treatment of Addictions

Relational perspectives on the nature of self and the unconscious have transformed how we can understand addictions and substance use problems. Addictions have received little attention in the contemporary literature and therapeutic approaches outside of psychoanalysis have been skeptical of psychoanalytic approaches. It is my contention that viewing substance use problems through the lens of a relational/multiple self-state model offers new clinical possibilities resulting in greater success in treating these patients. In this model, addictive behavior is seen as embedded in dissociated self-states. Therapy focuses on helping the patient to move from dissociation to a true multiplicity and a decreased dependence on substances.     

Getting Personal: Thoughts on Therapeutic Action Through the Interplay of Intimacy,Affect, and Consciousness

How do patients internalize new good object experience and how do these previously closed systems open up? What happens within and between analyst and patient that leads to the opening up of affective channels between them and allows consciousness to become transpersonal? The ways in which self-state experience becomes more fluid and cohesive, or less dissociated, is an affective process. This process occurs intersubjectively, as well as between self-states within each individual. When particular self-states come together between analyst and patient, especially those associated with pain and shame, disruption and instability may result within the mind-system (intrapsychic organization) of either or both partners. Managing the affective strain and psychic destabilization are vital tasks for the analyst and patient, in order for relationships between parts of the self (within one individual) to move from pain and hiddenness to compassionate recognition, thereby allowing and facilitating for parts of the self within the other individual to, in turn, move from pain and hiddenness to compassionate recognition. This is a core process of internal life, leading to the development of intimacy between self-states as well as between individuals.     

Affordance Compatibility Effect for Word Learning in Virtual Reality

Rich sensorimotor interaction facilitates language learning and is presumed to ground conceptual representations. Yet empirical support for early stages of embodied word learning is currently lacking. Finding evidence that sensorimotor interaction shapes learned linguistic representations would provide crucial support for embodied language theories. We developed a gamified word learning experiment in virtual reality in which participants learned the names of six novel objects by grasping and manipulating objects with either their left or right hand. Participants then completed a word–color match task in which they were tested on the same six words and objects. Participants were faster to respond to stimuli in the match task when the response hand was compatible with the hand used to interact with the named object, an effect we refer to as affordance compatibility. In two follow up experiments, we found that merely observing virtual hands interact with the objects was sufficient to acquire a smaller affordance compatibility effect, and we found that the compatibility effect was driven primarily by responses with a compatible hand and not by responses in a compatible spatial location. Our results support theoretical views of language which ground word representations in sensorimotor experiences, and they suggest promising future routes to explore the sensorimotor foundations of higher cognition through immersive virtual experiments.     

Implicit learning, thought-focused attention and obsessive-compulsive disorder: a replication and extension

Although significant empirical support exists for both cognitive and neurobiological models of obsessive-compulsive disorder (OCD), there have been few efforts to integrate findings. In this investigation, we attempted to link models by examining relationships between performance on information processing tasks posited to be markers of OCD-related neuropathology and a self-report measure of excessive thought-focused attention (cognitive self-consciousness; CSC). Congruent with predictions and prior research, OCD patients' performance was impaired in comparison to an anxious control group on the Serial Reaction Time (SRT) Task, a measure of implicit procedural learning. Following completion of the SRT, participants' awareness of the embedded stimulus pattern was assessed. As predicted, participants with OCD demonstrated superior performance on this task. Scoring on a measure of CSC correlated with performance on both tasks, although the amount of variance accounted for was modest. Evaluation of OCD symptom subgroups revealed greater procedural learning impairment in a hoarding subgroup. Implications for theory and treatment are discussed.
