Distraction Affects the Performance of Obstacle Avoidance During Walking

In this study, dual-task interference in obstacle-avoidance tasks during human walking was examined. Ten healthy young adults participated in the experiment. While they were walking on a treadmill, an obstacle suddenly fell on the treadmill in front of their left leg during either midswing, early stance, or late stance of the ipsilateral leg. Participants were instructed to avoid the obstacle, both as a single task and while they were concurrently performing a cognitive secondary task (dual task). Rates of failure, avoidance strategy, and a number of kinematic parameters were studied under both task conditions. When only a short response time was available, rates of failure on the avoidance task were larger during the dual task than during the single task. Smaller crossing swing velocities were found during the dual task as compared with those observed in the single task. The difference in crossing swing velocities was attributable to increased stiffness of the crossing swing limb. The results of the present study indicated that divided attention affects young and healthy individuals' obstacle-avoidance performance during walking.     

Boundary Distance Effects on Overshooting

Experiments with a subject-paced pursuit tracking task show that overshoot rate is dependent upon the distance between the target and the display boundary measured in the direction of movement, and that a previously noted inverse relationship with distance to the target is artifactual. The effect held for tasks with direct and reverse control-display relations, and for tasks with constant and variable target distances. The findings were consistent with Wetford’s (1968) hypothesis that a pursuit response is initiated with a ballistic, distance-covering, movement. Ralph Leonardo carried out extensive work in collecting data, Fred Hyde maintained the apparatus, and Georgie Green assisted in data analysis.     

Is the Critical Point for Aperture Crossing Adapted to the Person-Plus-Object System?

When passing through apertures, individuals scale their actions to their shoulder width and rotate their shoulders or avoid apertures that are deemed too small for straight passage. Carrying objects wider than the body produces a person-plus-object system that individuals must account for in order to pass through apertures safely. The present study aimed to determine whether individuals scale their critical point to the widest horizontal dimension (shoulder or object width). Two responses emerged: Fast adapters adapted to the person-plus-object system by maintaining a consistent critical point regardless of whether the object was carried while slow adapters initially increased their critical point (overestimated) before adapting back to their original critical point. The results suggest that individuals can account for increases in body width by scaling actions to the size of the object width but people adapt at different rates.     

Children in psychodynamic psychotherapy: changes in global functioning

This study was part of the Erica Process and Outcome Study. The aim was to investigate if children's global functioning improves after psychodynamic psychotherapy. Variables that may predict changes in global functioning were examined both statistically and qualitatively, for example, the child's age and gender; diagnosis and comorbidity; treatment variables. The sample consisted of 33 children (five to 10 years of age) who participated in psychodynamic psychotherapy with parallel work with parents. Twenty-nine children had at least one DSM-IV diagnosis, and 15 children had comorbid conditions. At the start of psychotherapy, the most frequent diagnoses were attention disorder and disruptive behaviour. Child psychotherapists rated the children's global functioning using CGAS and HCAM. Large effect sizes were obtained (d = 1.80 and d = 1.98). However, no statistical correlations were found between global functioning and the selected variables. In order to illuminate the complex connection between process and outcome the study was complemented with in-depth case studies where data were taken from questionnaires, completed by the child therapists every third month. Two child therapies were selected: one in which the therapist rated a large change and one in which a small change was rated (CGAS). The analysis showed that important individual change, for example, attainment of formulated goals, was not always reflected in the change rated using the CGAS. Findings suggest that psychodynamic child psychotherapy can be beneficial. However, further research is needed to identify factors that contribute to change in children's global functioning.     

Distress and Avoidance in Generalized Anxiety Disorder: Exploring the Relationships with Intolerance of Uncertainty and Worry

Theory and research suggest that treatments targeting experiential avoidance may enhance outcomes for patients with generalized anxiety disorder (GAD). The present study examined the role of experiential avoidance and distress about emotions in a treatment-seeking sample with a principal diagnosis of GAD compared with demographically matched nonanxious controls and sought to explore their shared relationship with two putative psychopathological processes in GAD: intolerance of uncertainty and worry. Patients with GAD reported significantly higher levels of experiential avoidance and distress about emotions compared with nonclinical controls while controlling for depressive symptoms, and measures of these constructs significantly predicted GAD status. Additionally, experiential avoidance and distress about anxious, positive, and angry emotions shared unique variance with intolerance of uncertainty when negative affect was partialed out, whereas only experiential avoidance and distress about anxious emotions shared unique variance with worry. Discussion focuses on implications for treatment as well as future directions for research.     

The Role of Fear-Avoidance Cognitions and Behaviors in Patients with Chronic Tinnitus

The current study investigated the role of fear-avoidance—a concept from chronic pain research—in chronic tinnitus. A self-report measure the “Tinnitus Fear-Avoidance Cognitions and Behaviors Scale (T-FAS)” was developed and validated. Furthermore, the role of fear-avoidance behavior as mediator of the relationship between anxiety sensitivity and tinnitus handicap was investigated. From a clinical setting, N = 373 patients with chronic tinnitus completed questionnaires assessing tinnitus handicap (Tinnitus Handicap Inventory), anxiety, depression (Hospital Anxiety and Depression Scale), anxiety sensitivity (Anxiety Sensitivity Index-3), personality factors (Big Five Inventory-10), and fear-avoidance. To analyze the psychometric properties, principal component analysis with parallel component extraction and correlational analyses were used. To examine a possible mediating effect, hierarchical regression analysis was applied. The principal component analysis resulted in a three-factor solution: Fear-avoidance Cognitions, Tinnitus-related Fear-Avoidance Behavior, and Ear-related Fear-Avoidance Behavior. Internal consistency was satisfactory for the total scale and all subscales. High correlations between tinnitus-related handicap scales, depressive and anxiety symptoms, and the T-FAS were found, whereas associations with personality factors were low. Moreover, results indicate a significant partial mediation of fear-avoidance behaviors in the relationship between anxiety sensitivity and the cognitive dimension of tinnitus handicap. Results show that fear-avoidance behavior plays an important role in tinnitus handicap. More attention should be paid to this concept in research and clinical practice of psychotherapy for chronic tinnitus.     

The Effects of Social Anxiety and State Anxiety on Visual Attention: Testing the Vigilance–Avoidance Hypothesis

A growing theoretical and research literature suggests that trait and state social anxiety can predict attentional patterns in the presence of emotional stimuli. The current study adds to this literature by examining the effects of state anxiety on visual attention and testing the vigilance–avoidance hypothesis, using a method of continuous visual attentional assessment. Participants were 91 undergraduate college students with high or low trait fear of negative evaluation (FNE), a core aspect of social anxiety, who were randomly assigned to either a high or low state anxiety condition. Participants engaged in a free view task in which pairs of emotional facial stimuli were presented and eye movements were continuously monitored. Overall, participants with high FNE avoided angry stimuli and participants with high state anxiety attended to positive stimuli. Participants with high state anxiety and high FNE were avoidant of angry faces, whereas participants with low state and low FNE exhibited a bias toward angry faces. The study provided partial support for the vigilance–avoidance hypothesis. The findings add to the mixed results in the literature that suggest that both positive and negative emotional stimuli may be important in understanding the complex attention patterns associated with social anxiety. Clinical implications and suggestions for future research are discussed.     

Factorial structure of a socialization goal questionnaire across non-migrant and migrant mothers in Germany

The aim of the study was to examine the factorial structure of a socialization goal questionnaire across three groups within Germany. The instrument has been previously used in cross-cultural research to assess autonomy and relatedness orientations, but lacks validation in contexts of migration. Additionally, the original instrument was modified to account for specific manifestations of both orientations. Participants were Turkish migrant, Former Soviet Union migrant and non-migrant mothers with children at preschool age, living in Germany. Single-group confirmatory factor analyses (CFAs) lead to modification of the initial model. Following multigroup CFAs revealed configurational and metric equivalence across the three groups. However, fit indices did not support equivalent structural relations between factors at the variance/covariance level. In sum, the results support the factorial structure of the socialization goal questionnaire, but point to mothers' different conceptualizations of the relationship between both dimensions.     

The impact of experiential avoidance on the relations between illness representations,pain catastrophising and pain interference in chronic pain

Objective: The aim of this study was to examine the effects of experiential avoidance (EA) on the indirect relationship of chronic pain patients’ illness representations to pain interference, through pain catastrophising

Design and main outcome measure: The sample consisted of 162 patients diagnosed with an arthritis-related or a musculoskeletal disorder. The effects of EA on the pathway between illness representations, pain catastrophising and pain interference were examined with PROCESS, a computational tool for SPSS

Results: After controlling for patient and illness-related variables and pain severity, the ‘illness representations–pain catastrophising–pain interference’ pathway was interrupted at the higher levels of EA. The reason was that, at the high levels of EA, either the relation of illness representations to pain catastrophising or the relation of pain catastrophising to pain interference was not statistically significant.

Conclusion: The findings indicate that EA is not a generalised negative response to highly aversive conditions, at least as far as the factors examined in this study are concerned. EA may rather reflect a coping reaction, the impact of which depends on its specific interactions with the other aspects of the self-regulation mechanism. At least in chronic pain, EA should become the focus of potential intervention only when its interaction with the illness-related self-regulation mechanism results in negative outcomes.
