Assessment of executive functioning in childhood epilepsy: The Tower of London and BRIEF

Children and adolescents with epilepsy are known to demonstrate executive function dysfunction, including working memory deficits and planning deficits. Accordingly, assessing specific executive function skills is important when evaluating these individuals. The present investigation examined the utility of two measures of executive functions—the Tower of London and the Behavioral Rating Inventory of Executive Functioning (BRIEF)—in a pediatric epilepsy sample. Ninety clinically referred children and adolescents with seizures were included. Both the Tower of London and BRIEF identified executive dysfunction in these individuals, but only the Tower of London variables showed significant relations with epilepsy severity variables such as age of epilepsy onset, seizure frequency, number of antiepileptic medications, etc. Further, the Tower of London and BRIEF variables were uncorrelated. Results indicate that objective measures of executive function deficits are more closely related to epilepsy severity but may not predict observable deficits, as reported by parents. Comprehensive evaluation of such deficits, therefore, should include both objective measures as well as subjective ratings from caregivers.     

The influence of environmental context in interpersonal observation–execution

Cyclical upper-limb movements involuntarily deviate from a primary movement direction when the actor concurrently observes incongruent biological motion. We examined whether environmental context influences such motor interference during interpersonal observation–execution. Participants executed continuous horizontal arm movements while observing congruent horizontal or incongruent curvilinear biological movements with or without the presence of an object positioned as an obstacle or distractor. When participants were observing a curvilinear movement, an object located within the movement space became an obstacle, and, thus, the curvilinear trajectory was essential to reach into horizontal space. When acting as a distractor, or with no object, the curvilinear trajectory was no longer essential. For observing horizontal movements, objects were located at the same relative locations as in the curvilinear movement condition. We found greater involuntary movement deviation when observing curvilinear than horizontal movements. Also, there was an influence of context only when observing horizontal movements, with greater deviation exhibited in the presence of a large obstacle. These findings suggest that the influence of environmental context is underpinned by the (mis-)matching of observed and executed actions as incongruent biological motion is primarily coded via bottom-up sensorimotor processes, whilst the congruent condition incorporates surrounding environmental features to modulate the bottom-up sensorimotor processes.     

College Adjustment and Subjective Well‐Being When Coping With a Family Member's Illness

Individuals coping with the chronic or terminal illness of a family member are presented with a unique challenge that may influence their adjustment and overall well‐being. This study investigated variables that relate to college adjustment and subjective well‐being, including attachment, social support, coping, and illness‐related constructs, in a sample of undergraduate students (N = 171) faced with this family crisis. The findings and counseling implications for this group are discussed.     

The Retentional and the Repressed: Does Freud's Concept of the Unconscious Threaten Husserlian Phenomenology?

This paper investigates the claims made by both Freudian psychoanalysic thought and Husserlian phenomenology about the unconscious. First, it is shown how Husserl incorporates a complex notion of the unconscious in his analysis of passive synthesis. With his notion of an unintentional reservoir of past retentions, Husserl articulates an unconscious zone that must be activated from consciousness in order to “come to life.” Second, it is explained how Husserl still does not account for the Freudian unconscious. Freud's unconscious could be called, in phenomenological terms, a repressed retentional zone that differs from both near and far retention. Finally, an analysis is offered for the significance of this psychoanalytic argument for phenomenology. Does phenomenology provide a complete account of the psychical life of the subject without the Freudian unconscious? Does phenomenology suggest, as is often done, that Freud's “discovery” of the unconscious is a fantastical invention? Or, does the Freudian unconscious represent a true stumbling block for phenomenology?     

The lived experience of alopecia areata: A qualitative study

This study explored experiences of individuals living with alopecia areata (AA) and alopecia universalis (AU) and investigated their accounts of adjusting to, and coping with, such conditions. Whilst previous research has primarily focused on the adverse psychosocial impact of alopecia, this investigation used Interpretive Phenomenological Analysis to provide a more holistic perspective. Biographical interviews were undertaken with 12 participants (7 women; 5 men) diagnosed with alopecia for periods ranging between 2 and 49 years. Results revealed that strategies used by participants evolved over time and that there were clear gender differences. In the early stages, participants did not want to contemplate that their hair loss would be lasting and managed the condition via concealment. Later coping strategies reflected an embodied acceptance with participants managing the effects of AA/AU and becoming more optimistic about living with the condition. Limitations of the study are discussed as well as implications for patient care.     

Knowledge of response location alone is not sufficient to generate social inhibition of return

Previous research has revealed that the inhibition of return (IOR) effect emerges when individuals respond to a target at the same location as their own previous response or the previous response of a co-actor. The latter social IOR effect is thought to occur because the observation of co-actor's response evokes a representation of that action in the observer and that the observation-evoked response code subsequently activates the inhibitory mechanisms underlying IOR. The present study was conducted to determine if knowledge of the co-actor's response alone is sufficient to evoke social IOR. Pairs of participants completed responses to targets that appeared at different button locations. Button contact generated location-contingent auditory stimuli (high and low tones in Experiment 1 and colour words in Experiment 2). In the Full condition, the observer saw the response and heard the auditory stimuli. In the Auditory Only condition, the observer did not see the co-actor's response, but heard the auditory stimuli generated via button contact to indicate response endpoint. It was found that, although significant individual and social IOR effects emerged in the Full conditions, there were no social IOR effects in the Auditory Only conditions. These findings suggest that knowledge of the co-actor's response alone via auditory information is not sufficient to activate the inhibitory processes leading to IOR. The activation of the mechanisms that lead to social IOR seems to be dependent on processing channels that code the spatial characteristics of action.     

Behavioral and neural correlates of disrupted orienting attention in posttraumatic stress disorder

Prior work has revealed that posttraumatic stress disorder (PTSD) is associated with altered (a) attentional performance and (b) resting-state functional connectivity (rsFC) in brain networks linked to attention. Here, we sought to characterize and link these behavioral and brain-based alterations in the context of Posner and Peterson’s tripartite model of attention. Male military veterans with PTSD (N = 49; all deployed to Iraq or Afghanistan) and healthy age-and-gender-matched community controls (N = 26) completed the Attention Network Task. A subset of these individuals (36 PTSD and 21 controls) also underwent functional magnetic resonance imaging (fMRI) to assess rsFC. The behavioral measures revealed that the PTSD group was impaired at disengaging spatial attention, relative to the control group. FMRI measures further revealed that, relative to the control group, the PTSD group exhibited greater rsFC between the salience network and (a) the default mode network, (b) the dorsal attention network, and (c) the ventral attention network. Moreover, problems with disengaging spatial attention increased the rsFC between the networks above in the control group, but not in the PTSD group. The present findings link PTSD to both altered orienting of spatial attention and altered relationships between spatial orienting and functional connectivity involving the salience network. Interventions that target orienting and disengaging spatial attention may be a new avenue for PTSD research.     

Aerobic exercise in the psychological treatment of adolescents.

A small group of psychiatrically institutionalized adolescents (16 boys, 11 girls) were assigned to a three-day-per-week running/aerobic exercise program or a regular physical activity class. The complete program continued over 9 weeks, with 11 subjects remaining throughout the program. Dependent measures of body-mass index, timed performance on a one-mile run, resting, exercise, and recovery heart rates, and measures of depression, mood-states, and self-efficacy were assessed pre-, mid-, and post-9-wk. treatment and at a 4-wk. follow-up. Improvements in depression, anxiety, hostility, confused thinking, and fatigue were shown in treated girls, with increases in vigor and self-efficacy for all treated subjects.
