Tense and agreement in German agrammatism

This study presents results from sentence-completion and grammaticality-judgment tasks with 7 German-speaking agrammatic aphasics and 7 age-matched control subjects examining tense and subject-verb agreement marking. For both experimental tasks, we found that the aphasics achieved high correctness scores for agreement, while tense marking was severely impaired. To account for the observed tense-agreement dissociation, we suggest that the functional category T(ense)/INFL(ection) is tense-defective in agrammatic aphasia, i.e., it is specified for [+/-Realis], but not for [+/-Past]. It will also be argued that other accounts, specifically the tree-pruning model, do not explain our findings.     

Posttraining prefrontal lesions impair jaw movement conditioning performance,but have no effect on accompanying heart rate changes

This experiment examined the role of the medial prefrontal cortex (mPFC) in regulating learned autonomic and somatomotor responses in rabbits using appetitive Pavlovian conditioning. Interstimulus interval (ISI) duration [i.e., the time between the onset of the conditioned stimulus (CS) and unconditioned stimulus (US)] was manipulated in order to determine whether ISI duration was related to the heart rate (HR) responses obtained during conditioning. Two groups received either a 1- or a 4-s ISI, with a tone as the CS and an intraoral pulse of water as the US. Another two groups received explicitly unpaired presentations of either the 1- or 4-s tone CS and water US. Few conditioned jaw movement (JM) or HR conditioned responses (CRs) were observed in the unpaired conditions. Significant JM conditioning was, however, elicited by the paired conditions, especially to the 4-s ISI. Consistent CS-evoked HR accelerations were observed in both ISI conditions. After five sessions of training, the mPFC was lesioned in half the animals. A separate group of paired animals received sham lesions. After surgical recovery, all animals received 3 days of postoperative training. During the first postoperative training session, JM CRs significantly declined in both groups with mPFC lesions in comparison to the groups with sham lesions. The mPFC lesions, however, did not affect the CS-evoked cardiac accelerations, which again occurred during postoperative training.

Cognitive Behavioral Therapy for Social Anxiety Disorder: Predictors of Treatment Outcome in a Quasi-Naturalistic Setting

We examined the outcomes of individual cognitive behavioral therapy (CBT) for social anxiety disorder (SAD) in a sample of 93 adults seeking treatment in a university outpatient clinic specializing in CBT for SAD. Treatment followed the structure of a manual, but number of sessions varied according to client needs. After approximately 20 weeks of therapy, patients’ social anxiety had decreased and their quality of life had increased. Patients with more severe SAD or comorbid major depressive disorder (MDD) at pretreatment demonstrated higher levels of social anxiety averaged across pre- and posttreatment. However, clinician-rated severity of SAD, comorbid MDD, or comorbid generalized anxiety disorder did not predict treatment outcome. Higher pretreatment scores on measures of safety behaviors and cognitive distortions were associated with higher social anxiety averaged across pre- and posttreatment and predicted greater decreases from pre- to posttreatment on multiple social anxiety outcome measures. We found no predictors of change in quality of life. Those with high levels of safety behaviors and distorted cognitions may benefit more from CBT, perhaps due to its emphasis on targeting avoidance through exposure and changing distorted thinking patterns through cognitive restructuring methods. Our study lends support to the body of research suggesting that manualized CBT interventions can be applied flexibly in clinical settings with promising outcomes for patients over a relatively short course of therapy.     

Overlapping and Distinct Cognitive Impairments in Attention-Deficit/Hyperactivity and Autism Spectrum Disorder without Intellectual Disability

Attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) are commonly comorbid, share genetic liability, and often exhibit overlapping cognitive impairments. Clarification of shared and distinct cognitive effects while considering comorbid symptoms across disorders has been lacking. In the current study, children ages 7–15 years assigned to three diagnostic groups:ADHD (n?=?509), ASD (n?=?97), and controls (n?=?301) completed measures spanning the cognitive domains of attention/arousal, working memory, set-shifting, inhibition, and response variability. Specific processes contributing to response variability were examined using a drift diffusion model, which separately quantified drift rate (i.e., efficiency of information processing), boundary separation (i.e., speed-accuracy trade-offs), and non-decision time. Children with ADHD and ASD were impaired on attention/arousal, processing speed, working memory, and response inhibition, but did not differ from controls on measures of delayed reward discounting, set-shifting, or interference control. Overall, impairments in the ASD group were not attributable to ADHD symptoms using either continuous symptom measures or latent categorical grouping approaches. Similarly, impairments in the ADHD group were not attributable to ASD symptoms. When specific RT parameters were considered, children with ADHD and ASD shared impairments in drift rate. However, children with ASD were uniquely characterized by a wider boundary separation. Findings suggest a combination of overlapping and unique patterns of cognitive impairment for children with ASD as compared to those with ADHD, particularly when the processes underlying reaction time measures are considered separately.     

Creativity through Connectedness: The Role of Closeness and Perspective Taking in Group Creativity

Achievements in various fields of creativity are resulting more and more from collaborative teams. This research investigated the role of interpersonal process variables, namely closeness and perspective taking in group creativity, with a 2 by 2 experimental design. Sixty-one 3-person groups assigned to 4 conditions (a: closeness and perspective taking, b: perspective taking, c: no closeness and no perspective taking, d: closeness). Group members collaboratively wrote stories that were rated by 3 independent expert judges. There was a positive main effect of closeness and negative main effect of perspective taking on group creativity scores. Moreover, the significant interaction between perspective taking and closeness displayed that combination of closeness with perspective taking negatively affect group creativity. These results indicate that closeness might be beneficial for group creativity only when it is not accompanied with perspective taking.     

Differenzialdiagnose schizoaffektive Störung versus bipolare Störung

This case presentation describes a 22-year-old woman after an episode of psychotic mania. Manic-psychotic and depressive episodes, partially with psychotic symptoms, and different diagnoses have been documented for the past 5 years, raising the question of the differential diagnosis between bipolar disorder and schizoaffective disorder. Depending on the classification (ICD-10 versus DSM-5), schizoaffective disorder is defined differently. According to ICD-10, schizoaffective episodes can be diagnosed when affective and schizophrenic symptoms occur simultaneously. In a different approach, DSM-V requires psychotic symptoms in the absence of major mood episodes for at least 2 weeks in the course of the disorder.     

Developmental differences in children’s interpersonal emotion regulation

Previous research on interpersonal emotion regulation (ER) in childhood has been rather unsystematic, focusing mainly on children’s prosocial behaviour, and has been conducted in the absence of an integrative emotion theoretical framework. The present research relied on the interpersonal affect classification proposed by Niven et al. (Emotion, 9:498–509, 2009) to investigate children’s use of different interpersonal ER strategies. The study drew on two samples: 180 parents of children aged between 3 and 8 years reported about a situation where their child was able to change what another person was feeling in order to make them feel better. In addition, 126 children between 3- and 8-years old answered two questions about how they could improve others’ mood. Results from both samples showed age differences in children’s use of interpersonal ER strategies. As expected, ‘affective engagement’ (i.e., focusing on the person or the problem) and ‘cognitive engagement’ (i.e., appraising the situation from a different perspective) were mainly used by 7–8 years-old, whereas ‘attention’ (i.e., distracting and valuing) was most used by 3–4 and 5–6 years-old. ‘Humor’ (i.e., laughing with the target) remained stable across the different age groups. The present research provides more information about the developmental patterns for each specific interpersonal emotion regulation strategy.     

Vividness of positive mental imagery predicts positive emotional response to visually presented Project Soothe pictures

Lang's bioinformational theory of mental imagery proposes that mental imagery and external stimuli engage emotional information-processing systems in similar ways. However, the positive and negative systems are thought to be distinct, so this similarity is likely to show a valence-specific effect. Therefore, we hypothesized that an individual's ability to construct vivid positive, but not negative, mental imagery would predict positive emotional responding to positive visual stimuli, independently of depressive symptoms. Our stimuli were pictures collected through Project Soothe for possible use in psychotherapy ( www.projectsoothe.com ); as these pictures were intended to induce soothing emotion, we hypothesized that theoretically linked variables Self-compassion and Self-criticism would also predict positive responding to the stimuli. A total of 214 participants completed an online study including validated questionnaire measures, mental imagery tasks, and a picture-rating exercise. Only Positive Imagery Vividness and Self-compassion were significant predictors of positive responding to the soothing pictures, even controlling for depressive symptoms, and Negative and General Imagery Vividness. These findings support Lang's theory and provide evidence for individual differences in a positive processing tendency shared across mental imagery-based and perceptual representations. As this relationship is distinct from depressive symptoms, future imagery-based psychotherapies might aim to influence this positive processing tendency.
