Role of the unquantified electroencephalography in psychiatric research

This paper outlines potential research applications of the unquantified (paper or digital) electroencephalography (EEG) in psychiatry. Three main areas are highlighted: first, the need for thorough familiarity with the unquantified EEG is emphasized, including the ability to confidently recognize all normal and abnormal activities that could influence further analysis of the record as well as artifacts that can contaminate the tracings; second, the fact that definitive studies relating EEG abnormalities to psychiatric symptomatology and clinical response are lacking; and third, the potential for EEG to be utilized as a tool to decrease the risk of invasive research studies is discussed.     

Natural Theology in Paul? Reading Romans 1.19–20

This reading of Romans 1.19–20 suggests that, viewed within the argumentative progression of the letter from 1.18–3.20, these verses are properly understood as a subversion of the premises of natural revelation, rather than an endorsement of them. The traditional account of Paul's argument, in which 1.19–20 announces a theology of natural knowledge of God, is contradicted both by Paul's wider theological commitments and by his attitude to the privileges of Judaism. An alternative construal of the argument considers it as an ad hominem strategy, in which the opening verses serve to recapitulate at the beginning of the argument the presuppositions that Paul seeks ultimately to overthrow.     

Division by multiplication

In two experiments, item-specific transfer was examined in simple multiplication and division with prime and probe problems separated by four to six trials. As was predicted by Rickard and Bourne's (1996) identical-elements model, response time (RT) savings were larger with identical (e.g., prime 63 divided by 7, probe 63 divided by 7) than with inverted (63 divided by 9 and 63 divided by 7) division problems, whereas identical (7 x 9 and 7 x 9) and inverted (9 x 7 and 7 x 9) multiplication problems produced equivalent transfer. Nonetheless, there was statistically significant transfer between inverted division problems. Furthermore, RT savings in the multiplication-to-division transfer conditions (e.g., prime 7 x 9, probe 63 divided by 7) indicated that multiplication mediated large-number division problems. These latter effects are not predicted by the identical-elements model but may be reconciled with the model by distinguishing associative transfer (facilitation owing to strengthening of a common problem node in memory) from mediated transfer (facilitation owing to mediation by a strengthened, related problem). Skilled adults can exploit the conceptual correspondences between multiplication and division facts in a highly efficient way to facilitate performance.     

More about brows: how poses that change brow position affect perceptions of gender

The speeded categorisation of gender from photographs of men's and women's faces under conditions of vertical brow and vertical head movement was explored in two sets of experiments. These studies were guided by the suggestion that a simple cue to gender in faces, the vertical distance between the eyelid and brow, could support such decisions. In men this distance is smaller than in women, and can be further reduced by lowering the brows and also by lowering the head and raising the eyes to camera. How does the gender-classification mechanism take changes in pose into account? Male faces with lowered brows (experiment 1) were more quickly and accurately categorised (there was little corresponding 'feminisation' of raised-brow faces). Lowering gaze had a similar effect, but failed to interact with head lowering in a simple manner (experiment 2). We conclude that the initial classification of gender from the facial image may not involve normalisation of the face image to a canonical state (the 'mug-shot view') for expressive pose (brow movement and direction of gaze). For head pose (relative position of the features when the face is not viewed head-on), normalisation cannot be ruled out. Some perceptual mechanisms for these effects, and their functional implications, are discussed.     

Distress in spouses of Vietnam veterans: associations with communication about deployment experiences

Emerging literature shows a consistent pattern of relationship and psychological distress in spouses or partners of combat veterans with symptoms of posttraumatic stress disorder (PTSD). One possible mechanism of partners' distress posited in clinical literature is that excessive discussion of traumatic events from deployment may have negative effects on partners. At the extreme, some partners are suggested to develop PTSD-like symptoms, or secondary traumatic stress. Despite these hypotheses, there have been few empirical tests of the effects of communicating about such events. In a sample of 465 combat veterans and their spouses who participated in the Family Interview Component of the National Vietnam Veterans Readjustment Study, we explored how the extent of couples' deployment-related communication was associated with partner relationships and psychological distress, and whether such associations were moderated by the severity of veterans' PTSD symptoms. Results showed that Vietnam-specific communication correlated negatively with relationship distress, but the effect was negligible after controlling for overall communication in the relationship. On the other hand, Vietnam-specific communication did not correlate with psychological distress, but the association was significantly moderated by veterans' PTSD symptom severity. Specifically, communication about Vietnam was increasingly and positively associated with partners' psychological distress as veterans' symptoms of PTSD rose into the clinical range, but nonsignificantly and negatively associated with such distress as PTSD symptoms decreased below this level. The findings support previous clinical recommendations that couples' discussions of potentially traumatic events be approached cautiously, and they suggest a need to attend to the content of couples' communications when conducting dyadic interventions for PTSD.     

Relationship between reaction time variability and motor skill development in ADHD

Slower and more variable reaction times to computerized tasks have been documented in children diagnosed with attention deficit/hyperactivity disorder (ADHD). Recent research supports a role for attentional lapses in generating abnormally variable and slow responses. However, given the association between ADHD and impairments in motor control, we hypothesized that slower or more variable reaction times might also correlate with motor development. The aim of this case-control study was to explore the relationship between motor function, reaction speed and variability, and ADHD. After comprehensive educational and clinical assessments, motor skill development was evaluated in 35 children ages 9 to 14 (19 with ADHD) using the Physical and Neurological Examination for Subtle Signs (PANESS) test battery. Finger-sequencing speed and variability were quantified with goniometers. Reaction times were measured with 20 trials each of computerized simple and choice (binary) tasks. Compared to healthy controls, children with ADHD had slower and more variable reaction times, and these findings correlated with impaired motor development (PANESS) and slow and variable finger sequencing (goniometers). Further studies of motor development in ADHD may identify factors influencing speed and variability of reaction times.     

Unemployed Adults’ Career Thoughts,Career Self‐Efficacy,and Interest: Any Similarity to College Students?

Little empirical knowledge about unemployed adults exists during a time when this group needs substantial career assistance. Because there is greater empirical understanding of college student career development compared with what is known about unemployed adults, a chi square and analyses of covariance were used to compare the career thinking, self‐efficacy, and interests of 169 unemployed adults seeking public job center assistance with that of 200 college students. Additionally, a diverse sample of 2,444 unemployed adults is demographically reviewed. Unemployed adults reported a higher level of Realistic interests and similar levels of negative career thinking and career decision‐making self‐efficacy compared with college students.     

Mapping novel labels to actions: how the rhythm of words guides infants' learning

We investigated the effect of lexical stress on 16-month-olds' ability to form associations between labels and paths of motion. Disyllabic English nouns tend to have a strong-weak (trochaic) stress pattern, and verbs tend to have a weak-strong (iambic) pattern. We explored whether infants would use word stress information to guide word-action associations during learning. Infants heard two novel words with either verb-like iambic stress or noun-like trochaic stress. Each word was paired with a single novel object performing one of two path actions and was tested using path-switch trials. Only infants in the iambic stress condition learned the association between the novel words and the path actions. To further investigate infants' difficulty in mapping the trochaic labels to the actions, we conducted an additional study in which infants were given an object switch task using the trochaic labels. In this case, infants were able to associate the trochaic labels with the objects, providing further support that infants use lexical stress to guide label-referent associations. This study demonstrates that by 16months, English-learning infants have developed a bias to expect disyllabic action labels to have iambic stress patterns, consistent with native language stress patterns.
