Estimating rates of chronic fatigue syndrome from a community-based sample: A pilot study

Most of the Chronic Fatigue Syndrome (CFS) epidemiological studies have relied on physicians who refer patients having at least 6 months of chronic fatigue and other symptoms. However, there are a number of potential problems when using this method to derive prevalence statistics. For example, some individuals with CFS might not have the economic resources to access medical care. Other individuals with CFS might be reluctant to use medical personnel, particularly if they have encountered physicians skeptical of the authenticity of their illness. In addition, physicians that are skeptical of the existence of CFS might not identify cases. In the present pilot study, a random community sample (N=1,031) was interviewed by telephone in order to identify and comprehensively evaluate individuals with symptoms of CFS and those who self-report having CFS. Different definitions of CFS were employed, and higher rates (0.2%) of CFS were found than in previous studies. Methodological benefits in using more rigorous epidemiological methods when estimating CFS prevalence rates are discussed.

A threat to Canadian national security: a lesbian soldier’s story

Before 1992, lesbians and gay soldiers were purged and discharged from the Canadian military for “reasons of homosexuality.” Those caught or suspected of homosexuality were subject to lengthy, humiliating, and degrading interrogations. This short story sheds light on this painful past. It is based on findings of a nationally funded pan-Canadian longitudinal study examining how Canadian military policies and practices influenced the lives of lesbian, gay, bisexual, and transgender soldiers and their partners. In total, 126 people were interviewed. While in the military, countless soldiers were investigated, numerous interrogated, many lost their careers, some committed suicide and others survived. Personal details have been changed to ensure the anonymity of the people, but it is their voices that tell this story. An official state apology was delivered November 28, 2017. Due to an impending class action court case, an agreement for compensation was also reached. Compensation and memorials will be forthcoming to those who were affected by the LGBTQI2+ purge campaign. To this day, no evidence exits that these soldiers were “ever” a threat to national security.     

On the Disambiguation of Meaning and the Effect of Cognitive Load

Most research supports a non-selective (or exhaustive) account of activation whereby multiple meanings of a word are initially activated (Degani and Tokowicz Quarterly Journal of Experimental Psychology, 63, 1266-1303, 2010). But what happens to the non-selected meaning of an ambiguous word (e.g., bark) and how is the decision made to select one meaning over the other? A great deal of research by Gernsbacher and colleagues (e.g., Gernsbacher and Faust 1991a) suggests that the non-selected meaning is “discarded” via active suppression. The present paper examines meaning-selection in ambiguous words using a word to elicit meaning context (rather than a sentence). Additionally, a manipulation of cognitive load (Experiment 2) was employed to examine these processes. Results support a suppression account of meaning selection. An updated conceptualization of ambiguity resolution is proposed.     

Detecting Duplication in Students’ Research Data: A Method and Illustration

Research integrity is core to the mission of higher education. In undergraduate student samples, self-reported rates of data fabrication have been troublingly high. Despite this, no research has investigated undergraduate data fabrication in a more systematic manner. We applied duplication screening techniques to 18 data sets submitted by psychology honors students for assessment. Although we did not identify any completely duplicated cases, there were numerous partial duplicates. Rather than indicating fabrication, however, these partial duplicates are likely a consequence of poor measure selection, insufficient data screening, and/or participant characteristics. Implications for the teaching and supervision of honors students are discussed.     

Parents’ Verbal Communication and Childhood Anxiety: A Systematic Review

Parents’ verbal communication to their child, particularly the expression of fear-relevant information (e.g., attributions of threat to the environment), is considered to play a key role in children’s fears and anxiety. This review considers the extent to which parental verbal communication is associated with child anxiety by examining research that has employed objective observational methods. Using a systematic search strategy, we identified 15 studies that addressed this question. These studies provided some evidence that particular fear-relevant features of parental verbal communication are associated with child anxiety under certain conditions. However, the scope for drawing reliable, general conclusions was limited by extensive methodological variation between studies, particularly in terms of the features of parental verbal communication examined and the context in which communication took place, how child anxiety was measured, and inconsistent consideration of factors that may moderate the verbal communication–child anxiety relationship. We discuss ways in which future research can contribute to this developing evidence base and reduce further methodological inconsistency so as to inform interventions for children with anxiety problems.     

Learning to Heal from Those Who Know! The “Lived” Experience of a Peer Support Program for Adult Survivors of Childhood Trauma

This study explored the dual phenomenon of experiencing a peer support residential trauma program from the perspective of (a) a client, and (b) a facilitator. It sought both positive and negative subjective interpretations. Participants were former clients and current facilitators of the program. Data were collected through a focus group, and analyzed using interpretative phenomenological analysis. One superordinate theme, altruistic growth, overarched 2 subordinate themes. The first, modeling through respect, included subthemes of respect and hope and empowerment. The second subordinate theme, reciprocal model of care, encapsulated personal challenges such as facing the mirror, old demons, and burnout and breaking points. Conversely, participants mused on these challenges as opportunities for further healing through opportunities for self-nurturing and gratitude. Implications for treatment of adult survivors of childhood trauma are discussed. For facilitators, the program was seen as offering further personal reflection and a giving forward that was interpreted as altruistic growth.     

Making sense of ourselves: self-narratives and personal identity

Some philosophers take personal identity to be a matter of self-narrative. I argue, to the contrary, that self-narrative views cannot stand alone as views of personal (or numerical) identity. First, I consider Dennett’s self-narrative view, according to which selves are fictional characters—abstractions, like centers of gravity—generated by brains. Neural activity is to be interpreted from the intentional stance as producing a story. I argue that this is implausible. The inadequacy is masked by Dennett’s ambiguous use of ‘us’: sometimes ‘us’ refers to real human beings, and sometimes ‘us’ refers to selves or fictional characters. Second, I consider Schechtmann’s view that self-narratives create persons (in the sense that she calls ‘characterization’ or personality. I argue that the sense in which a self-narrative creates a person cannot stand on its own: a person must already exist (in the sense of numerical identity) in order for there to be a self-narrative. Finally, I offer my own account of persons.     

Stimulus Parameters Underlying Sound-Symbolic Mapping of Auditory Pseudowords to Visual Shapes

Sound symbolism refers to non-arbitrary mappings between the sounds of words and their meanings and is often studied by pairing auditory pseudowords such as “maluma” and “takete” with rounded and pointed visual shapes, respectively. However, it is unclear what auditory properties of pseudowords contribute to their perception as rounded or pointed. Here, we compared perceptual ratings of the roundedness/pointedness of large sets of pseudowords and shapes to their acoustic and visual properties using a novel application of representational similarity analysis (RSA). Representational dissimilarity matrices (RDMs) of the auditory and visual ratings of roundedness/pointedness were significantly correlated crossmodally. The auditory perceptual RDM correlated significantly with RDMs of spectral tilt, the temporal fast Fourier transform (FFT), and the speech envelope. Conventional correlational analyses showed that ratings of pseudowords transitioned from rounded to pointed as vocal roughness (as measured by the harmonics-to-noise ratio, pulse number, fraction of unvoiced frames, mean autocorrelation, shimmer, and jitter) increased. The visual perceptual RDM correlated significantly with RDMs of global indices of visual shape (the simple matching coefficient, image silhouette, image outlines, and Jaccard distance). Crossmodally, the RDMs of the auditory spectral parameters correlated weakly but significantly with those of the global indices of visual shape. Our work establishes the utility of RSA for analysis of large stimulus sets and offers novel insights into the stimulus parameters underlying sound symbolism, showing that sound-to-shape mapping is driven by acoustic properties of pseudowords and suggesting audiovisual cross-modal correspondence as a basis for language users' sensitivity to this type of sound symbolism.
