Dissertation experiences of doctoral graduates from professional psychology programs

Worldwide, dissertation experiences are acknowledged to be challenging endeavors for students and the faculty members who advise them, and dissertation completion continues to be a concern when seeking to improve overall doctoral graduation rates. Although a number of factors have been associated with completion rates across disciplines, further research is needed within professional psychology graduate programs to understand overall student dissertation experiences. In this USA-based investigation, a mixed-method design was used to examine the experiences of 25 professional psychology doctoral graduates’ dissertation experiences, 12 of which were self-identified as positive and 13 as negative. Participants with positive experiences typically had supportive relationships with their dissertation chairs and committee members, which enhanced their research confidence and professional development. Participants with negative dissertation experiences typically had difficult relationships with dissertation chairs and committee members, which was associated with immediate and long-lasting negative consequences for participants’ professional growth and emotional well-being. The advisory working alliance was stronger for graduates with positive than negative experiences, although research attitudes and self-efficacy beliefs were not different between the two groups.     

Spatial properties of mechanisms for detection of moving dot targets in dynamic visual noise

The maximum displacement threshold for direction discrimination (dmax) was determined for single or paired dot targets moving discretely against a background of dynamic visual noise. dmax rose as the spatial density of noise was reduced, or when the interframe interval was decreased. dmax was greater for dot pairs than for single dots, and rose progressively as the distance between the dots was reduced. dmax was also greater if the orientation of the target dot pairs differed from the orientation of paired dots in the background noise. Dichoptic presentation of the target and background noise allowed the target to be detected with an accuracy that did not depend on displacement.     

Connecting the dots: Illusory pattern perception predicts belief in conspiracies and the supernatural

A common assumption is that belief in conspiracy theories and supernatural phenomena are grounded in illusory pattern perception. In the present research we systematically tested this assumption. Study 1 revealed that such irrational beliefs are related to perceiving patterns in randomly generated coin toss outcomes. In Study 2, pattern search instructions exerted an indirect effect on irrational beliefs through pattern perception. Study 3 revealed that perceiving patterns in chaotic but not in structured paintings predicted irrational beliefs. In Study 4, we found that agreement with texts supporting paranormal phenomena or conspiracy theories predicted pattern perception. In Study 5, we manipulated belief in a specific conspiracy theory. This manipulation influenced the extent to which people perceive patterns in world events, which in turn predicted unrelated irrational beliefs. We conclude that illusory pattern perception is a central cognitive mechanism accounting for conspiracy theories and supernatural beliefs.     

Genetic Counsellors and Private Practice: Professional Turbulence and Common Values

Genetic counsellors face tensions between past and future identities: between established values and goals, and a broadening scope of settings and activities. This study examines the advent of genetic counsellors in private practice in Australia and New Zealand from the perspectives of the small numbers working in this sector and those who have only worked in public practice. Semi-structured interviews were conducted with 16 genetic counsellors who had experience in private practice, and 14 genetic counsellors without private sector experience. Results demonstrated that circumstantial and personal factors can mitigate the challenges experienced and the amount of support desired by those who had established a private practice, and those who were employed by private companies. Notably, most participants with private sector experience perceived themselves to be viewed negatively by other genetic counsellors. Most participants without private sector experience expressed concern that the challenges they believed genetic counsellors face in private practice may impact service quality, but wished to address such concerns by providing appropriate support. Together, our results reinforce that participants in private and public sectors are strong advocates for peer support, multidisciplinary team work, and professional development. These core values, and seeking understanding of different circumstances and support needs, will enable genetic counsellors in different sectors to move forward together. Our results suggest supports that may be acted upon by members of the profession, professional groups, and training programs, in Australia, New Zealand, and overseas.     

Mindfulness‐based cognitive therapy is effective as relapse prevention for patients with recurrent depression in Scandinavian primary health care

This study examined the effectiveness of mindfulness‐based cognitive therapy (MBCT) in primary care for patients with recurrent depression (major depressive disorder: MDD). According to the World Health Organization (WHO), MDD is now the leading cause of disease burden in middle‐ and high‐income countries. Patients (N = 45) with three or more previous depressive episodes were recruited to participate in MBCT as a preventative intervention. Using a benchmarking approach, outcome data was compared with data from a recent efficacy study. The methodology is a rigorous approach to assessing effectiveness when evidence‐based UK protocols are transferred into the existing Scandinavian service delivery. Additionally, a person‐centred methodological approach was used to assess clinical significance on the Reliable Change Index (RCI). The analysis revealed comparable or larger effects from pre‐test to post‐test in reduced psychiatric symptoms, increased quality of life and level of mindfulness, and the effects were maintained over 14 months. Analysis of the relapse rate in the current study (16%) compared to the TAU in the efficacy study (68%) yielded an h value of 0.78, a moderate effect size. Only 13% dropped out of the treatment. According to the RCI findings, 65% to 67% of participants in the clinical group improved, no individual worsened, and women showed a significantly greater improvement of depression and anxiety than men. Therapeutic alliance and motivation had no impact on the outcome. The overall result suggests that MBCT can be implemented successfully in Scandinavian primary health care as a preventive intervention for patients with recurrent depression.     

Are children with Specific Language Impairment competent with the pragmatics and logic of quantification?

Specific Language Impairment (SLI) is understood to be a disorder that predominantly affects phonology, morphosyntax and/or lexical semantics. There is little conclusive evidence on whether children with SLI are challenged with regard to Gricean pragmatic maxims and on whether children with SLI are competent with the logical meaning of quantifying expressions. We use the comprehension of statements quantified with ‘all’, ‘none’, ‘some’, ‘some…not’, ‘most’ and ‘not all’ as a paradigm to study whether Spanish-speaking children with SLI are competent with the pragmatic maxim of informativeness, as well as with the logical meaning of these expressions.Children with SLI performed more poorly than a group of age-matched typically-developing peers, and both groups performed more poorly with pragmatics than with logical meaning. Moreover, children with SLI were disproportionately challenged by pragmatic meaning compared to their age-matched peers. However, the performance of children with SLI was comparable to that of a group of younger language-matched typically-developing children. The findings document that children with SLI do face difficulties with employing the maxim of informativeness, as well as with understanding the logical meaning of quantifiers, but also that these difficulties are in keeping with their overall language difficulties rather than exceeding them. The implications of these findings for SLI, linguistic theory, and clinical practice are discussed.
