“Atmosphere”, a Precursor of “Cognitive Schemas”: Tracing Tacit Phenomenological Influences on Cognitive Behaviour Therapy

Whilst individuals deal with divergent sorts of stimuli from the environment, they also tend to display some regularity in the way they respond to related patterns. These consistent responses can be conceptualised as cognitive schemas. A paramount component of Cognitive Behaviour Therapy (CBT) is the notion of cognitive schemas as they are a favoured point of therapeutic intervention. CBT as articulated by Beck in the 1960s owes intellectual acknowledgment to Merleau-Ponty and Heidegger and their notions of “atmosphere” and “clearing” respectively. This essay explores the notion of cognitive schema and atmosphere as applied to emotional pathology. It suggests that the well-known influence that phenomenology had on existential psychology could be extended to empirical clinical psychology, like CBT. The strategy adopted in this paper is to use Dreyfus’ ontological and epistemological distinction in psychopathology and then make a similar distinction, albeit using different terminology, in the CBT tradition. Some empirical findings from the literature are examined which render support to the existence of cognitive schemas and their crucial contributory role in the aetiology and maintenance of emotional disorders. It is noted that some of the features of these cognitive schemas were espoused well before Beck by Merleau-Ponty and the phenomenological-existential tradition.

Galvanic skin response in mood disorders: A critical review

To critically review the literature on Galvanic Skin Response (GSR) within Mood Disorder populations. GSR profiles were examined for the various types of Mood Disorder and their association with comorbidity, suicidality and predispositions. This review examined studies with emotional and non-emotional stimuli whilst aiming to identify a Mood Disorder GSR profile by comparisons with healthy controls and other psychological or physical disorders. A systematic search for relevant literature was conducted using PsychINFO, CINAHL and MEDLINE databases. Studies using emotional stimuli to measure GSR in mood disorder patients were included. Some studies did not use emotional stimuli, however were included as GSR measures were conducted separately from stimuli presentation. A greater proportion of studies reported results in support of a specific GSR profile for mood disorders as well as indicating GSR variation depending on type of disorder. Distinguishing the GSR profile from other psychological or physical disorders was more challenging, as it is less clear if pathology causes differences in GSR when issues such as comorbidity are present. Bilateral GSR differences, GSR differences between the left and right hand, were also reported in a number of studies. Results indicated mood disorder patients have low or flat GSR profiles, consistent with review expectations. Bilateral analysis also indicated a common left-hand bias among mood disorder patients

Psychophysiological research of borderline personality disorder: Review and implications for biosocial theory

According to the Biosocial theory, Borderline Personality Disorder (BPD) is developed by a biological predisposition to hyperarousal and hyperreactivity combined with an invalidating environment. Although widely supported by subjective measures, the impaired insight present in BPD may skew results, and thus psychophysiological measures have been suggested as an alternative method of examining possible biological differences in BPD. The current review aimed to critically assess psychophysiological research of BPD by electronic searching of relevant databases, with 22 articles meeting inclusion criteria. Results showed that in contrast to the hyperarousal proposed in the Biosocial theory, BPD was associated with hypoarousal and hyporeactivity to non-emotionally valenced stimuli. However, there was also evidence of BPD hyperreactivity towards negatively valenced stimuli, and impaired habituation during stressor tasks. As current psychophysiological results were inconsistent, it has been postulated that there may be possible subtypes of BPD. Further, evolutionary-based theories do not appear to adequately explain the complexity of emotion dysregulation in BPD, thus the Emotional Coherence theory has been proposed as an alternate method of conceptualising the role of psychophysiology in BPD. From the lack of clear or consistent findings, further research in the area appears necessary to determine the role of psychophysiology in BPD

Mindfulness-based treatment for bipolar disorder: A systematic review of the literature

Despite the increasing number of studies examining the effects of mindfulness interventions on symptoms associated with Bipolar Disorder (BD), the effectiveness of this type of interventions remains unclear. The aim of the present systematic review was to (i) critically review all available evidence on Mindfulness Based Cognitive Therapy (MBCT) as a form of intervention for BD; (ii) discuss clinical implications of MBCT in treating patients with BD; and (iii) provide a direction for future research. The review presents findings from 13 studies (N = 429) that fulfilled the following selection criteria: (i) included BD patients; (ii) presented results separately for BD patients and control groups (where a control group was available); (iii) implemented MBCT intervention; (iv) were published in English; (v) were published in a peer reviewed journal; and (vi) reported results for adult participants. Although derived from a relatively small number of studies, results from the present review suggest that MBCT is a promising treatment in BD in conjunction with pharmacotherapy. MBCT in BD is associated with improvements in cognitive functioning and emotional regulation, reduction in symptoms of anxiety depression and mania symptoms (when participants had residual manic symptoms prior to MBCT). These, treatment gains were maintained at 12 month follow up when mindfulness was practiced for at least 3 days per week or booster sessions were included. Additionally, the present review outlined some limitations of the current literature on MBCT interventions in BD, including small study sample sizes, lack of active control groups and idiosyncratic modifications to the MBCT intervention across studies. Suggestions for future research included focusing on factors underlying treatment adherence and understanding possible adverse effects of MBCT, which could be of crucial clinical importance

Assessing emotional reactivity: psychometric properties of the Perth emotional reactivity scale and the development of a short form

The Perth Emotional Reactivity Scale (PERS) is a 30-item self-report measure of trait levels of emotional reactivity. In this article, we examine the psychometric properties of the PERS subscale and composite scores in an adult community sample (N = 428), and develop an 18-item short form of the measure (PERS–S). The PERS and PERS–S are designed to assess the typical ease of activation, intensity, and duration of one\u27s emotional responses, and do so for positive and negative emotions separately. Our confirmatory factor analyses supported that the PERS and PERS–S both had the same theoretically congruent factor structure, and that all subscale and composite scores displayed high internal consistency reliability. Correlations with scores from established measures of psychopathology and emotion regulation also supported the validity of PERS and PERS–S scores. Our data therefore suggest that the PERS–S subscale and composite scores retain the psychometric strengths of their longer PERS counterparts. We conclude that both forms of the measure have good utility. Clinical and research applications are discussed

Estimation of Exoplanetary Planet-to-Star Radius Ratio with Homomorphic Processing

In this paper a homomorphic filtering scheme is proposed to improve the estimation of the planet/star radius ratio in astronomical transit signals. The idea is to reduce the effect of the short-term earth atmosphere variations. A two-step method is presented to compute the parameters of the transit curve from both the unfiltered and filtered data. A Monte Carlo analysis is performed by using correlated and uncorrelated noise to determine the parameters of the proposed FFT filter. The method is tested with observations of WASP-19b and WASP-17b obtained with the FORS2 instrument at the Very Large Telescope (VLT). The multi parametric fitting and the associated errors are obtained with the JKTEBOP software. The results with the white light of the exo-planet data mentioned above suggest that the homomorphic filtering can lead to substantial relative reductions in the error bars as high as 45.5% and 76.9%, respectively. The achieved reductions in the averaged error bars per channel were 48.4% with WASP-19b and 63.6% with WASP-17b. Open source MATLAB code to run the method proposed here can be downloaded from http://www.cmrsp.cl. This code was used to obtain the results presented in this paper

The Dynamic Nelson-Siegel model: empirical results for Chile and US

The model proposed by Nelson and Siegel (1987) has been used for several researcher to fit the yield curve. In this paper we propose a discrete-time version of that model by using dynamic factors, such that the model is dynamic in the sense proposed by Diebold and Li (2006). We found the exact parameters in the VAR model that generates Dynamic-Nelson-Siegel (DNS) which has a strong implication in the time-series properties of the interest rates: those should be model by an ARIMA(2,1,2). Finally we provide empirical evidence of the model for the cases of Chile and US, our finding matches previous results about the non-linear parameter of the model.Nelson-Siegel, Yield Curve, ARIMA

Assessing alexithymia: Psychometric properties and factorial invariance of the 20-item Toronto Alexithymia Scale in nonclinical and psychiatric samples

The 20-item Toronto Alexithymia Scale (TAS-20) is a self-report questionnaire designed to measure the three components of alexithymia; difficulty identifying feelings in the self (DIF), difficulty describing feelings (DDF), and externally orientated thinking (EOT). We examined the scale’s psychometric properties in Australian nonclinical (N = 428) and psychiatric (N = 156) samples. In terms of factorial validity, confirmatory factor analyses found the traditional 3-factor correlated model (DIF, DDF, EOT) to be the best and most parsimonious solution, but it did not reach adequate levels of goodness-of-fit in either sample. Several EOT items loaded poorly on their intended factor, and a reverse-scored item method factor was present; the factor structure of the scale was invariant across both samples. A higher-order factor model (with a single higher-order factor) was slightly inferior to the correlated models, but still tenable. The total scale score and DIF and DDF subscales displayed sound internal consistency, but the EOT subscale did not. We conclude that the TAS-20 has, for the most part, adequate psychometric properties, though interpretation should focus only on the total scale score and DIF and DDF subscales; we recommend the EOT subscale score not be used. Implications for clinical use and future revision of the scale are discussed
