Schizotypal personality and vulnerability to involuntary autobiographical memories

Background and objectives: Individuals who score high on positive schizotypy personality traits are vulnerable to more frequent trauma-related intrusive memories after a stressful event. This vulnerability may be the product of a low level of contextual integration of non-stressful material combined with a heightened sensitivity to a further reduction in contextual integration during a stressful event. The current study assessed whether high scoring schizotypes are vulnerable to frequent involuntary autobiographical memories (IAMs) of non-stressful material. Methods: A free-association word task was used. Participants completed three recorded trials which were then replayed to allow the identification of any associations where an involuntary autobiographical memory had come to mind. Self-report measures of schizotypy and anxiety were completed. Results: All participants retrieved at least one IAM from the three free-association word trials, with 70% experiencing two or more IAMs. Individuals scoring high in schizotypy reported more IAMs than those who scored low. Over 75% of the memories retrieved were neutral or positive in content. Limitations: The current study is an improvement on previous methodologies used to assess IAMs. However, bias due to retrospective recall remains a possibility. Conclusions: Individuals scoring high in schizotypy are vulnerable to an increased level of neutral intrusive memories which may be associated with a ‘baseline’ level of information-processing which is low in contextual integration.

The effect of BREEAM on clients and construction professionals

The effects and influence of the Building Research Establishment’s Environmental Assessment Methods (BREEAM) on construction professionals are examined. Most discussions of building assessment methods focus on either the formal tool or the finished product. In contrast, BREEAM is analysed here as a social technology using Michel Foucault’s theory of governmentality. Interview data are used to explore the effect of BREEAM on visibilities, knowledge, techniques and professional identities. The analysis highlights a number of features of the BREEAM assessment process which generally go unremarked: professional and public understandings of the method, the deployment of different types of knowledge and their implication for the authority and legitimacy of the tool, and the effect of BREEAM on standard practice. The analysis finds that BREEAM’s primary effect is through its impact on standard practices. Other effects include the use of assessment methods to defend design decisions, its role in both operationalizing and obscuring the concept of green buildings, and the effect of tensions between project and method requirements for the authority of the tool. A reflection on assessment methods as neo-liberal tools and their adequacy for the promotion of sustainable construction suggests several limitations of lock-in that hinder variation and wider systemic change.

Individual differences in mental control predict involuntary musical imagery

The experience of earworms, a type of involuntary musical imagery, may reflect a systematic failure in mental control. This study focused on how individual differences in each of two factors, schizotypy, or “openness to experience”, and thought suppression might relate to the appearance of the involuntary musical image (earworm). Schizotypy, was measured by Raine’s schizotypal personality questionnaire (SPQ; Raine, 1991) and thought suppression was measured by the White Bear Suppression Inventory (WBSI; Wegner & Zanakos, 1994). Each was found to contribute independently to the overall experience of involuntary musical imagery. Schizotypy was correlated with the length and disruptiveness of earworms, the difficulty with which they were dismissed and the worry they caused, but was not correlated with the frequency of such intrusive imagery. In turn, schizotypy was predicted by suppression and intrusion components of WBSI. The WBSI is associated with the length, disruptiveness, difficulty dismissing and interference but not with the worry caused or the frequency of earworms. The assumption of “ownership” of earworms was also found to affect the extent to which the earworms were considered worrying. Multiple regression analysis showed that both schizotypy and the WBSI predicted the difficulty with which unwanted musical images were dismissed, but that the WBSI accounted for additional variance on top of that accounted for by schizotypy. Finally we consider how earworm management might relate to wider cognitive processes.

Examining vulnerability to involuntary memories in schizophrenia comorbid with post-traumatic stress disorder

The current study explored whether individuals diagnosed with schizophrenia and a high level of PTSD symptoms experience more frequent neutral intrusive memories than individuals diagnosed with schizophrenia with low level PTSD symptoms. Results supported a vulnerability to neutral intrusive memories within the comorbid group, which did not seem to be related to psychotic symptom severity. It is possible that a subgroup of psychotic individuals’ process information in a manner that make them susceptible to frequent intrusive memories, characteristic of a PTSD presentation. A longitudinal study is required to specify the development of this vulnerability so as to inform future interventions.

The classification of involuntary musical imagery: the case for earworms

Involuntary musical imagery (INMI) is the subject of much recent research interest. INMI covers a number of experience types such as musical obsessions and musical hallucinations. One type of experience has been called earworms, for which the literature provides a number of definitions. In this paper we consider the origins of the term earworm in the German language literature and compare that usage with the English language literature. We consider the published literature on earworms and conclude that there is merit in distinguishing between earworms and other types of types of involuntary musical imagery described in the scientific literature: e.g. musical hallucinations, musical obsessions. We also describe other experiences that can be considered under the term INMI. The aim of future research could be to ascertain similarities and differences between types of INMI with a view to refining the classification scheme proposed here.

Stigma and risky behaviors among male clients of sex workers in the UK in 2001

This paper builds on existing theoretical work on sex markets (Della Giusta, Di Tommaso, and Strøm, 2009a). Using data from the British Sexual Attitudes Survey, we aim to replicate the analysis of the demand for paid sex previously conducted for the US (Della Giusta, Di Tommaso, Shima and Strøm, 2009b). We want to test formally the effect of attitudes, risky behaviors and personal characteristics on the demand for paid sex. Findings from empirical studies of clients suggest that personal characteristics (personal and family background, self-perception, perceptions of women, sexual preferences etc), economic factors (education, income, work) as well as attitudes towards risk (both health hazard and risk of being caught where sex work is illegal), and attitude towards relationships and sex are all likely to affect demand. Previous theoretical work has argued that stigma plays a fundamental role in determining both demand and risk, and that in particular due to the presence of stigma the demand for sex and for paid sex are not, as has been argued elsewhere, perfect substitutes. We use data from the British Sexual Attitudes Survey of 2001 to test these hypotheses. We find a positive effect of education (proxy for income), negative effects of professional status (proxies for stigma associated with buying sex), positive and significant effects of all risky behavior variables and no significant effects of variables which measure the relative degree of conservatism in morals. We conclude with some policy implications.

Clients who stalk psychologists: prevalence, methods, and motives

There is emerging recognition that psychologists are susceptible to various forms of intrusiveness by clients, including stalking. Information regarding the contexts in which stalking emerges and the behaviors to which clinicians are subjected is limited. A random sample of Australian psychologists (N = 1,750) was surveyed to ascertain the prevalence, nature, and occupational impact of stalking by clients. Of the 830 respondents, 19.5% had been stalked for 2 weeks or more. Psychologists typically perceived the stalking to be motivated by resentment (42%) or infatuation (19%). Most practitioners altered their professional practice as a consequence of the harassment and 29% considered leaving the profession. Stalking by clients is a salient professional issue that requires greater attention to better manage conduct that is potentially damaging to both therapists and clients.

Not the same : a comparison of female and male clients seeking treatment from problem gambling counselling services

Previous studies of problem gamblers portray this group as being almost exclusively male. However, this study demonstrates that females comprised 46% of the population (n = 1,520) of persons who sought assistance due to concerns about their gambling from the publicly-funded BreakEven counselling services in the state of Victoria, Australia, in one 12-month period. This suggests that the model of service delivery which is community based counselling on a non-residential basis may be better able to attract female clients than treatment centres where males predominate such as veterans centres. A comparative analysis of the social and demographic characteristics of female and male gamblers within the study population was undertaken. As with previous studies, we have found significant differences between males and females who have sought help for problems associated with their gambling. Gender differences revealed in this study include females being far more likely to use electronic gaming machines (91.1% vs. 61.4%), older (39.6 years vs. 36.1 years), more likely to be born in Australia (79.4% vs. 74.7%), to be married (42.8% vs. 30.2%), living with family (78.9% vs. 61.5%) and to have dependent children (48.4% vs. 35.7%), than males who present at these services. Female gamblers (A$7,342) reported average gambling debts of less than half of that owed by males (A$19,091). These gender differences have implications for the development and conduct of problem gambling counselling services as it cannot be assumed that models of service which have demonstrated effectiveness with males will be similarly effective with females.

Choosing response scale labels and length: guidance for researchers and clients

There has been much debate over the optimal format for scales, particularly in regard to two key issues - the labelling of points and the overall length of response scales. This paper reviews the evidence regarding the advantages of different scale types and lengths, and provides guidance as to what scale types suit different research objectives. Using a direct comparison of 400 responses on 5-point and 11 -point scales to the same question, by the same people, we examine some of the important differences previously found and then illustrate the impact they have on data quality and useability. Our conclusion, based on past research and our own analysis, is that longer, balanced and unlabelled scales offer the maximum flexibility and reliability in the majority of cases.

In search of a future strategy for market research services : clients' views on market research suppliers

The market research environment is transforming rapidly and research suppliers may not be keeping up with changing research client needs. This paper examines research client perceptions of current research supplier performance and future competencies. The key findings are that research suppliers need to move their staffing profiles beyond technical expertise in conducting research (generating outputs) to functional expertise in understanding research outcomes within internal and external organizational contexts. The transition from data collector to expert advisor may involve anew business model and new pricing strategies based on intellectual expertise rather than margins on data collection services.
