Validity of a short form of the WISC-III in children with traumatic head injury

The concurrent, construct, and criterion validities of Donders' (in press) short form of the Wechsler Intelligence Scale for Children - Third Edition (WISC-III) were evaluated in a sample of 171 children with traumatic head injury (THI). Correlations between the short-form deviation quotients and their full-length counterparts were statistically significant. Confirmatory factor analysis revealed that a four-factor model (composed of Verbal Comprehension, Perceptual Organization, Freedom from Distractibility, and Processing Speed) fit the data relatively well. The short-form deviation quotients also had statistically significant correlations with length of coma. It is concluded that this short form is an accurate and valid alternative to the full-length WISC-III in children with THI.

A Group of Black South Africans' Experience of Telling their Untold Stories about the Apartheid Era

The aim of this research was to explore a group of black South Africans' experiences of telling their untold stories of survival about the apartheid era. The expectation was that if they did become more aware of these alternative stories, it could have a far-reaching effect on their lives. A qualitative study was conducted with a group of seven black South African survivors of the apartheid era, ranging in age from 42–62 years (males =5, females =2). These participants formed part of an earlier study investigating their perceptions regarding factors that helped them to survive the apartheid era. For the present study, unstructured interviews were conducted focusing on their subjective experiences after the initial study. Analysis of the data yielded seven prevalent themes, namely a positive experience that made a difference, gaining of a positive attitude, not all white people are bad, transgressing the past and moving on, awareness of personal strengths, forgiveness and starting to talk to family and friends. The participants became aware of their untold stories of survival and experienced a positive change within themselves, towards others, the past and the future.     

Isolement et solitude au travail : l’exemple des agents d’accueil de parcs urbains. Des effets pathogènes aux processus de régulation et de dégagement

Through action-research case study in the area of “Parks and Gardens”, this paper focused on the relations between “aloneness”, “loneliness” and “solitude” at work and their necessary distinctions. The Socio-Clinical work psychology approach used during the intervention helped to highlight some key elements. While aloneness characterizes a stretched between the subject and its external environment link, loneliness and solitude are defined as intra-subjective process mainly emotional psycho. These last notions remain in any case a test for physical and psychological occupational health. It seems that the outcomes depend largely on the ability of the subject to convert aloneness to solitude. In our case study three valences of aloneness with different level of risk for health, were underline: solitude, as creative aloneness; defensive aloneness; and loneliness. The advantages of this new approach for prevention are discussed in the positioning relative to other work on the subject.     

An adolescent perspective on injury recovery and the return to sport

ObjectivesThe purpose of this investigation was to examine adolescent athletes' injury recovery and return-to-sport experiences. Given previous research highlighting competence, autonomy, and relatedness concerns among returning athletes (Podlog & Eklund, 2006), we sought to examine the extent to which basic psychological needs theory (BPNT: Ryan & Deci, 2007) could be used as framework for interpreting the research findings.DesignA qualitative design was employed in the present investigation.MethodEleven Australian athletes (M age = 15.3) who had incurred a range of severe injuries (e.g., anterior cruciate ligament tears, shoulder dislocations) were interviewed on 2–3 occasions (n = 27 interviews) spanning an 11-month period.ResultsAnalysis of the data revealed the following four key themes: (a) injury stress, (b) coping strategies, (c) experiences with social support, and (d) recovery outcomes. Injury stress provides insights into a range of stressors and strain responses reported by the adolescents across the recovery phases, while the theme on coping highlights the specific strategies used to maintain motivation, reduce uncertainties associated with the injury experience, and to keep focused on future athletic attainment. The third theme, experiences with social support, considers the transactions the adolescents held with members of their social network throughout their recovery. The final theme, recovery outcomes, describes participant perceptions of a successful/unsuccessful recovery and stress-related growth.ConclusionsResults suggest that competence and relatedness issues highlighted in BPNT may be relevant in exploring adolescent athletes' injury experience. Somewhat less evidence for the autonomy dimension of BPNT was apparent in adolescent comments.     

Distinguishing multi-voxel patterns and mean activation: Why, how, and what does it tell us?

The introduction of multi-voxel pattern analysis (MVPA) to the functional magnetic resonance imaging (fMRI) community has brought a deeper appreciation for the diverse forms of information that can be present within fMRI activity. The conclusions drawn from MVPA investigations are frequently influenced by both the ability to decode information from multi-voxel patterns and mean activation levels. In practice, MVPA studies vary widely in why and how they test for differing overall response levels. In this article, I examine the place of univariate information in MVPA investigations. I first discuss the variety of interpretations given to finding univariate response differences. I go on to discuss some of the analysis approaches used to investigate and compare univariate and multivariate sources of information, which can illuminate their respective contributions. It will be important for the MVPA and general fMRI community to continue to discuss and debate these important issues.     

Pupil diameter measurement errors as a function of gaze direction in corneal reflection eyetrackers

Pupil dilation is a useful, noninvasive technique for measuring the change in cognitive load. Since it is implicit and nonverbal, it is particularly useful with preverbal or nonverbal participants. In cognitive psychology, pupil dilation is most often measured by corneal reflection eye-tracking devices. The present study investigates the effect of gaze position on pupil size estimation by three common eye-tracking systems. The task consisted of a simple object pursuit situation, as a sphere rotated around the display screen. Systematic errors of pupil size estimation were found with all three systems. Implications for task-elicited pupillometry, especially for gaze-contingent studies such as object tracking or reading, are discussed.     

Life Events may Contribute to Family Communication About Cancer Risk Following BRCA1/2 Testing

We assessed whether certain life events contributed to the communication about cancer risk within families who have undergone BRCA1/2 testing. We also explored what type of resources participants would have valued to help in supporting family communication about genetic information. Two hundred and forty-six individuals (218 women, 28 men) who received a BRCA1/2 genetic test result 3 to 10 years earlier (mean of 6.4 years) participated in a telephone interview. Participants were asked about the occurrence of a number of life events (cancer diagnosis, death, uptake of prophylactic surgery, and providing care to a family member with cancer) in their family since their BRCA1/2 test result disclosure and, for each occurrence, whether it fostered family communication about cancer risk. A total of 182 participants (74 %) reported that they or one of their relatives received a cancer diagnosis, 176 (72 %) reported that someone died in their family, and 73 (30 %) stated that they or one of their relatives undertook a prophylactic surgery. During this period, 109 participants (44 %) also provided care for a family member who had cancer. Among participants who reported these life events, family communication was fostered by these events in proportions varying from 50 % (death) to 69 % (cancer diagnosis). Our results indicate that life events may contribute to family communication about cancer risk. Further research is needed to determine whether these events provide a “window of opportunity” to reach family members, address their needs and concerns about cancer, update family cancer history, and introduce genetic counseling and risk assessment.     

Acceptance of Genetic Counseling and Testing in a Hospital-Based Series of Patients with Gynecological Cancer

Referral of patients with endometrial (EC) and/or ovarian cancer (OC) for genetic counseling is based on age at diagnosis and family history. Many patients with hereditary cancers are missed by following this strategy. We determined acceptance and mutation detection rate of offering genetic counseling and testing to unselected EC and OC patients. Therefore, in 2007, EC and OC patients were invited for genetic counseling and testing. Patients were asked for their reasons to accept or decline. Nineteen out of fifty-two EC patients (36 %) and twenty-two out of thirty-five OC patients (63 %) accepted genetic counseling, mainly to receive risk assessment for themselves and relatives. Counseling was declined mainly because patients did not want more tests or had no relatives for whom it was relevant. Eighteen out of nineteen EC patients (95 %) and twenty out of twenty-two OC patients (91 %) underwent genetic testing. One EC patient carried an MSH6 mutation (mutation detection rate: 6 %). BRCA1/2 mutations were found in two out of twenty OC patients (10 %). Eleven patients (29 %) received surveillance recommendations for themselves and their relatives. Finally, family history recorded by the gynecologist was compared to that taken by the clinical geneticist. Gynecologists reported family history in ten out of forty-one participants (24 %). In conclusion, genetic counseling and testing are acceptable to patients with OC and/or EC. The 10 % BRCA1/2 mutation detection rate and underreporting of family history by gynecologists warrant referral for genetic counseling for all OC patients, followed by BRCA1/2 testing if indicated. We recommend that microsatellite instability and immunohistochemical analysis be performed in all EC patients, followed by genetic counseling if appropriate. These strategies will lead to better cancer prevention in gynecological cancer patients and their relatives.     

Post-response stimulation and the Simon effect: Further evidence of action-effect integration

The recently proposed action-concept view of perceptual-motor behaviour posits that a stimulus which consistently follows a certain response will become associated with that response. Some evidence in favour of this view comes from the finding that the size of the Simon effect can be altered by the inclusion of post-response stimuli. However, only one study has investigated the effects of including same-side in addition to opposite-side post-response stimuli, as well as a neutral Simon condition, and, possibly because of a failure of random assignment, the results from that study were inconclusive. In light of this limitation, a Simon experiment was performed in which the location of post-response stimulation was manipulated within subjects. The results showed that: (1) the Simon effect can both decrease and increase in the presence of post-response stimuli, and (2) the amounts of Simon interference and Simon facilitation are both affected by post-response stimuli, whereas performance on neutral trials is not. These findings provide additional support for the action-concept view and suggest that further research concerning this new approach is warranted.
