Place learning in scopolamine-treated rats: the roles of distal cues and catecholaminergic mediation

Experiments 1 and 2 tested the hypothesis that cholinergic receptor antagonists impair place learning in a water maze by interfering with the processing of distal, visual cues. Extramaze cues were offered to rats in the form of geometrical patterns arranged on the inner circumference of a curtain surrounding the water maze. In Experiment 1 the animals were offered both the distal cues and proximal cues in the form of pingpong balls in fixed positions on the surface of the water while only distal cues were present in Experiment 2. Animals were injected with either scopolamine (0.5 mg/kg body wt) or saline 20 min prior to the daily place learning sessions. Upon reaching criterion level performance the animals were tested on "rotation" sessions on which the distal cues were displaced. The outcome of such "rotations" demonstrated that-regardless of the presence or absence of proximal cues-scopolamine-treated rats relied at least as much as normal animals on the distal cues. The acquisition phase of both Experiments 1 and 2 demonstrated an almost complete lack of scopolamine-associated impairment in acquisition and performance of the place learning task. In Experiment 3 (when scopolamine was no longer administered) the subjects of Experiment 2 were exposed to a series of pharmacological "challenges" of their place learning performance and eventually to surgical ablation of the anteromedial prefrontal cortex. The outcome of the pharmacological challenges and the postoperative test of task performance demonstrated that the place learning performance of animals which had acquired the task under scopolamine was mediated by a neural substrate dissimilar to the substrate of task performance in normal animals. Rats acquiring the task while deprived of the cholinergic system demonstrated above-normal contributions to task mediation from catecholaminergic-probably dopaminergic-mechanisms and tentative results pointed to a "shift" toward prefrontal task mediation.

Rumination mediates the relationship between impaired cognitive control for emotional information and depressive symptoms: A prospective study in remitted depressed adults

Impaired cognitive control may be an important vulnerability factor for depression. Moreover, impairments in cognitive control have been proposed as a crucial process underlying ruminative thinking. The present study investigates the influence of impaired cognitive control for emotional information on rumination and depressive symptoms in a prospective design with a 1 year follow up in a clinical sample. Thirty remitted depressed adults completed the Internal Shift Task (IST), a measure of cognitive control of emotional information, at baseline. Moreover, questionnaires measuring rumination (RRS) and depressive symptoms (BDI-II) were administered. One year later participants were contacted again and asked to complete the BDI-II and RRS. Mediation analyses showed a significant influence of impaired cognitive control for emotional information at baseline on depressive symptoms one year later, which was fully mediated by rumination. These findings underscore the importance of cognitive control abilities as a process underlying rumination and as a vulnerability factor for depression. They can stimulate translational research to improve the effectiveness of interventions that aim to decrease vulnerability by targeting cognitive control.     

Depressive symptoms and cognitive control in a mixed antisaccade task: Specific effects of depressive rumination

Growing empirical evidence suggests that cognitive and affective problems in depression may be a reflection of cognitive control impairments. However, to date, the nature of such impairments is still poorly understood and further investigation of this topic is required to advance current knowledge on the underlying vulnerability factors for depression. Using a mixed antisaccade paradigm, the present study examined if depressive symptoms in general, and more specifically rumination, are related to impairments in cognitive control functions such as inhibition and switching. The results on antisaccade latency and error rates indicated that depressive symptoms in general were not related to impairments in inhibition and switching. However, rumination was associated with impaired inhibition such that high, compared to low, ruminators had slower antisaccade latencies. No group differences were observed on antisaccade error rates. Implications for understanding the underlying vulnerability factors for the development of depressive symptoms are discussed.     

Mood-congruent attention and memory bias in dysphoria: Exploring the coherence among information-processing biases

Recent studies indicate that depression is characterized by mood-congruent attention bias at later stages of information-processing. Moreover, depression has been associated with enhanced recall of negative information. The present study tested the coherence between attention and memory bias in dysphoria. Stable dysphoric (n = 41) and non-dysphoric (n = 41) undergraduates first performed a spatial cueing task that included negative, positive, and neutral words. Words were presented for 250 ms under conditions that allowed or prevented elaborate processing. Memory for the words presented in the cueing task was tested using incidental free recall. Dysphoric individuals exhibited an attention bias for negative words in the condition that allowed elaborate processing, with the attention bias for negative words predicting free recall of negative words. Results demonstrate the coherence of attention and memory bias in dysphoric individuals and provide suggestions on the influence of attention bias on further processing of negative material.     

Avatar‐based counselling for young people within school counselling. Qualitative analysis of client experience

Background

This study is a qualitative analysis of clients’ experiences of a new avatar based counselling intervention, based on the ‘ProReal’ software ( www.proreal.world ). The intervention was piloted in eight secondary schools in the UK in 2016.

Aims

Twenty‐nine participants (53% of the full sample) were interviewed about their use of the software, experience of the intervention, process of change and views about its helpfulness.

Materials and Methods

Interviews were semi‐structured and were analysed using thematic analysis.

Results

The analysis shows that the intervention was potentially attractive to these clients, particularly those enthusiastic about digital software and clients who found visual communication helpful. The software provided additional opportunities for clients to communicate their inner worlds to the counsellor and supported the development of insight. Male clients, in particular, commented on its helpfulness.

Discussion

There is an indication that digital imagery supported the process of change in counselling and the development of meaning bridges: both internally and with the counsellor (Stiles, 2011; Stiles et al., 1990). However, the software could be experienced as an obstacle when clients wanted to talk about specific problems or ‘vent’ their feelings. All clients who reported that they did not find the software helpful were female. There were a number of suggestions about developing the software to increase opportunities for expression as well as appropriateness for clients from different minority ethnic backgrounds.

Conclusion

Use of digital software in counselling has a potential to enhance communication and support a process of change, particularly with male clients, those who find visual communication helpful, and clients enthusiastic about digital technology. Further research is needed to develop the intervention and compare it to the use of other creative media in counselling.     

Psychological type and counselling psychology trainees’ choice of counselling orientation

Clarifying the factors which influence choice of counselling orientation is important. This study investigated whether psychological type is associated with choice of orientation in counselling psychology trainees. Sets of questionnaires were sent to 210 counselling psychology trainees in four universities, which resulted in a sample of 84 participants. The measures were the Keirsey Temperament Sorter II and a short demographic questionnaire which also asked open-ended questions about chosen orientation. Participants who preferred SJ (Sensing-Judging) were more likely to choose the CBT model, NFJ (Intuition-Feeling-Judging) types the Psychodynamic model and NFPs (Intuition-Feeling-Perceiving) the Person-Centred model.     

Worrying and rumination are both associated with reduced cognitive control

Persistent negative thought is a hallmark feature of both major depressive disorder and generalized anxiety disorder. Despite its clinical significance, little is known about the underlying mechanisms of persistent negative thought. Recent studies suggest that reduced cognitive control might be an explanatory factor. We investigated the association between persistent negative thought and switching between internal representations in working memory, using the internal shift task (IST). The IST was administered to a group of undergraduates, classified as high-ruminators versus low-ruminators, or high-worriers versus low-worriers. Results showed that high-ruminators and high-worriers have more difficulties to switch between internal representations in working memory as opposed to low-ruminators and low-worriers. Importantly, results were only significant when the negative stimuli used in the IST reflected personally relevant worry themes for the participants. The results of this study indicate that rumination and worrying are both associated with reduced cognitive control for verbal information that is personally relevant.     

Kognitive Dissonanz nach Entscheidungen und psychische Erkrankungen

Building upon Grawe’s consistency theory the target of this study was to examine if cognitive dissonance has an influence on mental disorders. More precisely, whether post-decisional cognitive dissonance (1) is more pronounced in patients with mental disorders and (2) whether it correlates with symptom burden. Obsessive-compulsive disorder patients (OCD; n?=?15), depressive patients (n?=?20) and controls (n?=?42) completed a post-decisional cognitive dissonance scale as well as a scale assessing their respective symptom burden. Solely OCD patients showed heightened cognitive dissonance compared to controls (p?=?0.019). Among depressive patients, however, a very high correlation was found to exist between symptom burden and cognitive dissonance (r?=?0.70). Therefore, OCD seems to be related to increased cognitive dissonance which supports the assumption that cognitive dissonance plays a role in this mental disorder.
