Paradoxical consequences of Balzer''s and G?hde''s criteria of theoreticity. Results of an application to ten scientific theories

It is shown that the criteria of T-theoreticity proposed by Balzer and Gähde lead to strongly counterintuitive and in this sense paradoxical results: most of the obviously empirical or at least nontheoretical terms come out as theoretical. This is demonstrated for a lot of theories in different areas. On the way, some improved and some new structuralist theory-reconstructions are given. The conclusion is drawn that the T-theoreticity of a term cannot possibly be proved on the basis of the mathematical structure of theory T alone (as Gähde and Balzer suggest). Rather, an independent notion of pre-T-theoreticity and-more importantly-of empiricity is needed; i.e., not empirical and not pre-T-theoretical are independent, necessary but not sufficient conditions for T-theoretical (this is also a necessary complement of Sneed's original criterion). Finally it is asked whether the structuralist criterion of T-theoreticity complemented by such independent conditions would be a satisfactory answer to Putnam's challenge, and the answer again is negative: the criterion is not able to distinguish between empirically contentful and completely contentless (superfluous) theoretical terms.     

Remarks on “equivalent linear logistic test models” by Bechger,Verstralen, and Verhelst (2002)

This paper discusses a new form of specifying and normalizing a Linear Logistic Test Model (LLTM) as suggested by Bechger, Verstralen, and Verhelst (Psychometrika, 2002). It is shown that there are infinitely many ways to specify the same normalization. Moreover, the relationship between some of their results and equivalent previous results in the literature is clarified, and it is shown that the goals of estimating and testing a single element of the weight matrix, for which they propose new methods, can be reached by means of simple, well-known tools already implemented in published LLTM software.     

Stroop facilitation in tinnitus patients: an experiment conducted via the world wide web.

Cognitive mechanisms have been proposed to play an important role in tinnitus. In the present study, tinnitus participants were administered an emotional Stroop test via the Internet, incorporating words related to tinnitus concerns. In line with previous research using this Web-based version of the emotional Stroop test, faster color naming was demonstrated for concern-relevant words relative to neutral words. The present results thus provided support for a role for cognitive factors that are important for the understanding of tinnitus. However, future research is warranted in order to clarify the precise mechanisms involved in tinnitusrelated Stroop effects.     

The Role of Simple Semantics in the Process of Artificial Grammar Learning

This study investigated the effect of semantic information on artificial grammar learning (AGL). Recursive grammars of different complexity levels (regular language, mirror language, copy language) were investigated in a series of AGL experiments. In the with-semantics condition, participants acquired semantic information prior to the AGL experiment; in the without-semantics control condition, participants did not receive semantic information. It was hypothesized that semantics would generally facilitate grammar acquisition and that the learning benefit in the with-semantics conditions would increase with increasing grammar complexity. Experiment 1 showed learning effects for all grammars but no performance difference between conditions. Experiment 2 replicated the absence of a semantic benefit for all grammars even though semantic information was more prominent during grammar acquisition as compared to Experiment 1. Thus, we did not find evidence for the idea that semantics facilitates grammar acquisition, which seems to support the view of an independent syntactic processing component.     

From Equality‐Based Respect to Environmental Activism: Antecedents and Consequences of Global Identity

Global identity reflects social identification with the world and the largest, most inclusive human ingroup and is generally associated with behavior that serves the world and all humans, such as transnational cooperation or proenvironmental engagement. While the outcomes of being globally identified are well‐established, the antecedents of global identity are only partially explored. Drawing from research suggesting that respect fosters identification in small groups, we argue that the general experience of being respected as an equal by others increases global identification. In an online study with 469 Germans (students and nonstudents), we tested the relation between equality‐based respect and global identification in a structural equation model, with proenvironmental intentions and donation behavior as outcome variables. As expected, equality‐based respect, but not other forms of social recognition (need‐based care and achievement‐based social esteem), predicted global identity while higher global identity, in turn, predicted proenvironmental activism. These effects were substantial beyond known predictors of proenvironmental behavior and thus suggest that equality‐based respect represents an important facet of responses to global challenges.     

Music fan personality stereotyping in a sample of South African young adults

This study aimed to elicit stereotypes about personality characteristics of young adults residing in South Africa, based solely on music genres. Participants were 941 undergraduate students at a South African university. They responded to a number of surveys about music genre preferences and personality traits. Data were analysed for trends and patterns in personality attributions based on music genre preferences. The results indicated that participants hold distinct stereotypes about the personality traits, so that those with who preferred Classical, Blues and Jazz music were seen to display higher openness to experience than comparison groups with other music genre preferences. Those with Rap, Reggae and Folk music genre preferences were stereotyped as artistic and unconventional. Young South African adults appear to use musical preference to define personality.     

Cognitive behavioral therapy in practice: therapist perceptions of techniques,outcome measures,practitioner qualifications,and relation to research

Cognitive behavioral therapy (CBT) has a strong evidence base for several psychiatric disorders, however, it may be argued that currently there is no overall agreement on what counts as ‘CBT’. One reason is that CBT is commonly perceived as encompassing a broad range of treatments, from purely cognitive to purely behavioral, making it difficult to arrive at a clear definition. The purpose of the present study was to explore practicing therapists’ perceptions of CBT. Three hundred fifty members of two multi-disciplinary interest groups for CBT in Sweden participated. Mean age was 46 years, 68% were females, 63% psychologists and mean number of years of professional experience was 12 years. Participants completed a web-based survey including items covering various aspects of CBT practice. Overall, therapist perceptions of the extent to which different treatment techniques and procedures were consistent with CBT were in line with current evidence-based CBT protocols and practice guidelines, as were therapists’ application of the techniques and procedures in their own practice. A majority of participants (78%) agreed that quality of life or level of functioning were the most important outcome measures for evaluating treatment success. Eighty percent of therapists believed that training in CBT at a basic level was a requirement for practicing CBT. There was a medium size Spearman correlation of r_s=.46 between the perceived importance of research to practice and the extent to which participants kept themselves updated on research. Implications for training, quality assurance, and the effectiveness of CBT in clinical practice are discussed.     

Group acceptance and commitment therapy (ACT) for bipolar disorder and co-existing anxiety – an open pilot study

Previous studies have supported acceptance and commitment therapy (ACT) for reducing impairment related to various chronic conditions. ACT may possibly be beneficial for bipolar disorder (BD) with co-existing anxiety, which is associated with a poorer treatment outcome. Efforts are needed to identify suitable psychological interventions for BD and co-existing anxiety. In this open clinical trial, we included 26 patients with BD type 1 or 2 at an outpatient psychiatric unit specializing in affective disorders. The intervention consisted of a 12-session manualized group treatment that included psychoeducation, mindfulness, engaging in values-based behaviour, cognitive defusion, acceptance and relapse prevention modules. Participants completed four self-report questionnaires covering anxiety symptoms (Beck Anxiety Inventory - BAI), depressive symptoms (Beck Depression Inventory - BDI-II), quality of life (Quality of Life Inventory - QOLI) and psychological flexibility (Acceptance and Action Questionnaire - AAQ-2) before, during and after the treatment. At post-treatment, the participants reported significant improvements in all outcome measures, with large effects (Cohen’s d between 0.73 and 1.98). The mean reduction in anxiety symptoms was 45%. At post-treatment, 96% of the patients were classified as responders on at least one of the outcome measures. A limitation is that the trial is uncontrolled. The results suggest that ACT has the potential to be an effective treatment for BD patients with co-existing anxiety. Further randomized studies are warranted.
