Effects of feedback reliability on feedback-related brain activity: A feedback valuation account

Adaptive decision making relies on learning from feedback. Because feedback sometimes can be misleading, optimal learning requires that knowledge about the feedback’s reliability be utilized to adjust feedback processing. Although previous research has shown that feedback reliability indeed influences feedback processing, the underlying mechanisms through which this is accomplished remain unclear. Here we propose that feedback processing is adjusted by the adaptive, top-down valuation of feedback. We assume that unreliable feedback is devalued relative to reliable feedback, thus reducing the reward prediction errors that underlie feedback-related brain activity and learning. A crucial prediction of this account is that the effects of feedback reliability are susceptible to contrast effects. That is, the effects of feedback reliability should be enhanced when both reliable and unreliable feedback are experienced within the same context, as compared to when only one level of feedback reliability is experienced. To evaluate this prediction, we measured the event-related potentials elicited by feedback in two experiments in which feedback reliability was varied either within or between blocks. We found that the fronto-central valence effect, a correlate of reward prediction errors during reinforcement learning, was reduced for unreliable feedback. But this result was obtained only when feedback reliability was varied within blocks, thus indicating a contrast effect. This suggests that the adaptive valuation of feedback is one mechanism underlying the effects of feedback reliability on feedback processing.     

How Therapy With Victims of Political Trauma Repairs the Third—Commentary on Gómez and Kovalskys’s Work in the Context of Postdictatorship Chile

In this discussion I use the concept of the moral Third to designate the position in which we experience the world as lawful because repair is possible. Repair takes place through acknowledgment of harming and consequent suffering. This form of acknowledgment, coupled with social recognition, is considered by the authors to be a crucial part of the therapeutic work with victims of collective trauma, especially of torture by the Pinochet security police. In relation to Gómez’s case, I discuss how the moral Third, the representation of a lawful world, is shattered by attacks on the victim’s family. Further, the witnessing function is reversed and perverted in torture, where the torturer presents a blank face and denies the very suffering he is inducing. The experience of betrayal becomes the core issue which the therapist seeks to address through the attachment relationship itself. In relation to Kovalskys’ case I consider how the moral Third of the activists, the belief in the possibility of a world in which all can live, is attacked in order to affirm the paranoid view that “only one can live.” The lived experience of this traumatizing attack is that the child becomes imbued with the sense of not deserving life, of having gained life at the expense of the other. Helping the patient to testify publicly to her personal history and truth becomes part of the healing process in the context of collective trauma.     

Thai Norms for Name,Image, and Category Agreement,Object Familiarity,Visual Complexity,Manipulability, and Age of Acquisition for 480 Color Photographic Objects

Normative databases containing psycholinguistic variables are commonly used to aid stimulus selection for investigations into language and other cognitive processes. Norms exist for many languages, but not for Thai. The aim of the present research, therefore, was to obtain Thai normative data for the BOSS, a set of 480 high resolution color photographic images of real objects (Brodeur et al. in PLoS ONE 5(5), 2010.  https://doi.org/10.1371/journal.pone.0010773). Norms were provided by 584 Thai university students on eight dimensions: name agreement, object familiarity, visual complexity, category agreement, image agreement, two types of manipulability (graspability and mimeability), and age of acquisition. The results revealed comparatively similar levels of name agreement to Brodeur et al. especially when unfamiliar items were factored out. The pattern of intercorrelations among the Thai psycholinguistic norms was comparable to previous studies and our cross-linguistic correlations were robust for the same set of pictures in English and French. Conjointly, the findings extend the relevancy of the BOSS to Thailand, supporting this photographic resource for investigations of language and other cognitive processes in monolingual, multilingual, and brain-impaired populations.     

Breath Versus Emotions: The Impact of Different Foci of Attention During Mindfulness Meditation on the Experience of Negative and Positive Emotions

Mindfulness meditation yields beneficial effects on the processing of emotions. However, it is still unclear whether the focus of attention during meditation influences these effects. In the present study we aimed at comparing the effects of breathing meditation and emotion-focused meditation on the immediate and delayed processing of negative and positive emotions. The study included 65 adult novice meditators who were exposed to positively and negatively valenced film clips. Participants were randomly assigned to three conditions. While watching the films at t1, they were asked to mindfully focus on their breath (condition 1), on emotions (condition 2), or on nothing in particular (condition 3). Ten minutes later at t2, comparable film clips were shown but all participants watched them without taking up a mindful attitude. Dependent measures were emotional states at t1 and t2. Participants of both meditation conditions particularly showed a more preferable delayed emotional reaction to negative stimuli than participants of the control condition. Breathing meditation and emotion-focused meditation may constitute effective emotion regulation strategies to deal with negatively valenced emotional states.     

The Impact of Chronic Health Conditions as an Underlying Challenge on Couple’s Wellbeing

Chronic health conditions affect over 100 million Americans (Cano and Leonard in J Clin Psychol 62(11):1409–1418, 2006). Many clinicians are not integrating chronic physical health symptoms into psychotherapy. There is a complexity of issues that arise within the context of chronic health conditions. Making more need for couple and family therapists, whose primary focus is on a systemic family perspective, to understand how chronic health conditions are impacting family systems when they present for therapy (Canavarro and Dattilio in Contemp Fam Ther 33:87–90, 2011; Poleshuck et al. in Prof Psychol 41(4):312–318, 2010). The correlation of chronic health conditions on marriages and relationships has received limited attention in clinical research. This secondary data analysis examines the differences in overall well-being and psychological distress of individuals and couples seeking therapy who report a presence of chronic health conditions. Original research on the relationship between chronic health conditions and well-being, as measured by comparison of means, will be presented. Few studies investigate how chronic health conditions, when not the primary reason for seeking therapy, influence wellbeing and distress upon entering therapy. This study included 2742 participants from a clinical sample of individuals and couple seeking therapy in a family therapy clinic at a university training clinic. Independent t-tests, as well as ANOVA, were run to compare well-being and psychological distress of individuals and couples in the sample. Results showed significant differences in both overall wellbeing and psychological distress for both individuals who reported chronic illness for themselves, or their partners, than those that reported no chronic illness. There were also significant differences between groups on both well-being and psychological distress [F (2, 2706)?=?47.55, p?=?.00, F (2, 2697)?=?54.59, p?=?.00]. This results showed significant differences in well-being when no member of the couple has chronic health conditions, one member, or both members, with both members decreasing wellbeing significantly. This study demonstrates that chronic health conditions impact both the individual diagnosed, their partners, and is especially impactful if both members of a couple are diagnosed with chronic health conditions. Study limitations and clinical implications are also discussed.     

Does Rumination Mediate the Association of Private Prayer,Stress, and Their Interaction with Depression among Christians? A Cross-Sectional Study

Mechanisms underlying significant associations between different types of prayer and depression are unknown. Based on the conceptualization of prayer as stress buffering coping style and the Response Style Theory, we proposed that rumination mediates the association of prayer types and stress with depression. This cross-sectional study (N?=?227 Christians, M_age 41.74, SD 14.82, age range 18–82 years, 76% female) used path modeling to test whether rumination mediated the associations between prayer types and prayer types by stress interactions with depression. Rumination fully mediated the associations of the colloquial and ritual prayer by stress interactions with depressive symptoms, while meditative and petitionary prayer was directly associated with depressive symptoms. Further, petitionary prayer and the ritual prayer by stress interaction were associated with more and not with less rumination and depressive symptoms, respectively. Summarized, first empirical evidence supports an integration of prayer, stress, and rumination into one model of depression. However, the exact nature of their interplay depends on the prayer type. If replicated, our findings allow the integration of prayer into cognitive-behavioral treatment of depression in religious and spiritual clients.     

Introspective disputes deflated: the case for phenomenal variation

Sceptics vis-à-vis introspection often base their scepticism on ‘phenomenological disputes’, ‘introspective disagreement’, or ‘introspective disputes’ (ID) (see Kriegel in Phenomenol CognSci 6(1):115–136, 2007; Bayne and Spener in Philos Issues 20(1):1–22, 2010; Schwitzgebel in Perplexities of consciousness, MIT Press, Cambridge, 2011): introspectors massively diverge in their opinions about experiences, and there seems to be no method to resolve these issues. Sceptics take this to show that introspection lacks any epistemic merit. Here, I provide a list of paradigmatic examples, distill necessary and sufficient conditions for IDs, present the sceptical argument encouraged by IDs, and review the two main strategies (resolution and containment) to reject such a scepticism. However, both types of strategies are unsatisfactory. In order to save introspection from the looming sceptical threat, I advocate a deflationary strategy, based on either an ‘Argument from Perceptual Kinship’ or an ‘Argument from Ownership’. In the end, there cannot be any genuine IDs, for nothing can fulfil the reasonable conditions for IDs. What looks like IDs may instead be indicators of phenomenal variation. Debates that look like IDs may then arise even if introspection were a perfect method to know one’s mind. Thus, scepticism vis-à-vis introspection based on IDs rests on shaky grounds.
