Properties of intermodal transfer after dual visuo- and auditory-motor adaptation

Previous work documented that sensorimotor adaptation transfers between sensory modalities: When subjects adapt with one arm to a visuomotor distortion while responding to visual targets, they also appear to be adapted when they are subsequently tested with auditory targets. Vice versa, when they adapt to an auditory-motor distortion while pointing to auditory targets, they appear to be adapted when they are subsequently tested with visual targets. Therefore, it was concluded that visuomotor as well as auditory-motor adaptation use the same adaptation mechanism. Furthermore, it has been proposed that sensory information from the trained modality is weighted larger than sensory information from an untrained one, because transfer between sensory modalities is incomplete. The present study tested these hypotheses for dual arm adaptation. One arm adapted to an auditory-motor distortion and the other either to an opposite directed auditory-motor or visuomotor distortion. We found that both arms adapted significantly. However, compared to reference data on single arm adaptation, adaptation in the dominant arm was reduced indicating interference from the non-dominant to the dominant arm. We further found that arm-specific aftereffects of adaptation, which reflect recalibration of sensorimotor transformation rules, were stronger or equally strong when targets were presented in the previously adapted compared to the non-adapted sensory modality, even when one arm adapted visually and the other auditorily. The findings are discussed with respect to a recently published schematic model on sensorimotor adaptation.     

State anxiety impairs attentional control when other sources of control are minimal

Research suggests anxiety impairs attentional control; however, this effect has been unreliable. We argue that anxiety’s impairment of attentional control is subtle, and can be obscured by other non-emotional sources of control. We demonstrate this by examining conflict adaptation, an enhancement in attentional control following a trial with high conflict between distracter and target stimuli. Participants completed a Stroop task featuring incongruent (e.g. RED in green font; high-conflict) and control (e.g. +++ in green font; low-conflict) trials. More state-anxious participants showed greater Stroop interference following control trials, but interference was uniformly low following incongruent trials. This suggests state anxiety can impair attention, but other sources of top-down control – such as conflict adaptation – can easily overcome this impairment. This is consistent with recent theories of anxious cognition and shows that anxiety researchers must attend to the dynamics and sources of attentional control.     

Enhanced conflict-driven cognitive control by emotional arousal,not by valence

Emotion is widely agreed to have two dimensions, valence and arousal. Few studies have explored the effect of emotion on conflict adaptation by considering both of these, which could have dissociate influence. The present study aimed to fill the gap as to whether emotional valence and arousal would exert dissociable influence on conflict adaptation. In the experiments, we included positive, neutral, and negative conditions, with comparable arousal between positive and negative conditions. Both positive and negative conditions have higher arousal than neutral ones. In Experiment 1, by using a two-colour-word Flanker task, we found that conflict adaptation was enhanced in both positive and negative contexts compared to a neutral context. Furthermore, this effect still existed when controlling stimulus–response repetitions in Experiment 2, which used a four-colour-word Flanker task. The findings suggest emotional arousal enhances conflict adaptation, regardless of emotional valence. Thus, future studies should consider emotional arousal when studying the effect of emotion on conflict adaptation. Moreover, the unique role of the emotional context in conflict-driven cognitive control is emphasised.     

A mixed-methods process evaluation of a goal management intervention for patients with polyarthritis

Process evaluations of newly developed interventions are necessary to identify effective and less effective intervention components. First aim of this study was to identify key components of a psychosocial goal management intervention from the perspective of participants, and second aim was to evaluate the intervention’s fidelity. A mixed-methods approach was applied to 24 interviews with participants post-intervention and 16 audio recordings of random training sessions. Participants experienced three key components: (1) the content, in which specific exercises helped to raise awareness and (intention to) change goal management behaviour, (2) person-focused approach, specifically, the nurse as trainer and personal fit of the approach, and (3) social mechanisms, including facilitating group processes and interpersonal processes. Adherence to the protocol by the trainers was high, while differences were found in the degree to which they were able to apply the intended collaborative approach and psychological communication skills. The applied design provided valuable insights into the processes that took place. Both the effects experienced by participants in relationship to the content, approach and social mechanisms as well as the strengths and weaknesses found with regard to fidelity provide insights that can inform the development and implementation of person-focused interventions.     

Adaptation of CBT for Traumatized Egyptians: Examples from Culturally Adapted CBT (CA-CBT)

In this article we illustrate how CBT can be adapted to a traumatized Egyptian population with Islamic beliefs, giving examples from our adaptation of Culturally Adapted–CBT (CA-CBT) for this cultural group. We discuss a culturally sensitive assessment measure of local somatic complaints and cultural syndromes that was devised based on clinical experience with traumatized Egyptians. We also demonstrate how to normalize symptoms, create positive expectancy about the treatment, and educate about trauma. We give examples of how mindfulness can be adapted for an Egyptian Islamic population, and we describe local religious strategies, such as dhikr (religious chanting), salah (ritualistic prayer), and dua (supplication), that may be used to promote attentional shift from rumination topics and to teach attentional control. We describe how “loving kindness” can be adapted for this group. We outline how to modify culturally generated catastrophic cognitions and how to conduct interoceptive exposure and to create positive re-associations in a culturally sensitive manner. We describe how worry themes are explored and addressed based on a heuristic panic attack–PTSD model; how to teach anger management in a culturally sensitive way; and how to address sleep-related problems in this population. We suggest using cultural transitional “rituals” at the end of the treatment to give patients a sense of closure and a positive feeling of transformation. A case example is presented to illustrate cultural challenges associated with delivering CA-CBT to an Egyptian population. We introduce certain concepts such as cultural grounding and explanatory model bridging, both therapeutic techniques that increase adherence, positive expectancy, and cultural consonance.     

Development and validation of the REMINT: a reflection measure for individuals and teams

A growing number of studies have investigated the role of team reflexivity, the extent to which teams reflect on and adapt their functioning. However, the way team reflexivity has been conceptualized and operationalized reveals several weaknesses, in particular the conception as a unidimensional construct. To provide greater conceptual clarity, we therefore propose a team reflexivity framework that integrates four interacting but distinct reflexive processes. In four studies, we focus on reflection as a fundamental reflexive process, and develop and validate an extended multidimensional reflection measure that captures the relevant dimensions of quality and quantity of reflection and the key transition processes of information seeking and information evaluation. Moreover, in order to delineate two common composition methods, we develop and validate a direct consensus and a referent-shift consensus version of the reflection measure. Data collected from a total of 803 students and employees in four studies revealed excellent construct validity, as well as good nomological validity (Studies 1 and 2). Furthermore, we found evidence of the criterion-related validity at the team level (Study 3) and the individual level (Study 4). Together, the results demonstrate the effectiveness of our measure, revealing consistent relations with outcome measures and diverse behavioural indicators across different contexts.
