Attention,Memory, and Language after Pediatric Ischemic Stroke

A previous study evaluating receptive language after unilateral brain damage in childhood hypothesized lateralized attention and memory deficits without direct measurement. Our study directly measured attention, memory, and language in order to evaluate empirically the severity and laterality of sequelae. The performances of 11 individuals with a unilateral ischemic-lesion (7 right and 4 left hemisphere) were compared to controls matched on age, sex, and socioeconomic status. Results suggest subtle but persistent deficits in verbal memory, functional memory, and speed of processing after a lesion to either hemisphere. Lesions sustained before two years of age were associated with the lowest IQ scores. Our findings provide support for a configural representation of language that can to some extent compensate for inefficient or damaged components (Bates, 1994), and the middle-ground lateralization position (Thal et al., 1991) that asserts initial hemispheric specialization with the potential for reorganization.     

Psychophysiological evidence for the genuineness of swimming-style colour synaesthesia

Recently, swimming-style colour synaesthesia was introduced as a new form of synaesthesia. A synaesthetic Stroop test was used to establish its genuineness. Since Stroop interference can occur for any type of overlearned association, in the present study we used a modified Stroop test and psychophysiological synaesthetic conditioning to further establish the genuineness of this form of synaesthesia. We compared the performance of a swimming-style colour synaesthete and a control who was trained on swimming-style colour associations. Our results showed that behavioural aspects of swimming-style colour synaesthesia can be mimicked in a trained control. Importantly, however, our results showed a psychophysiological conditioning effect for the synaesthete only. We discuss the theoretical relevance of swimming-style colour synaesthesia according to different models of synaesthesia. We conclude that swimming-style colour synaesthesia is a genuine form of synaesthesia, can be mimicked behaviourally in non-synaesthetes, and is best explained by a re-entrant feedback model.     

Stopping while going! Response inhibition does not suffer dual-task interference

Although dual-task interference is ubiquitous in a variety of task domains, stop-signal studies suggest that response inhibition is not subject to such interference. Nevertheless, no study has directly examined stop-signal performance in a dual-task setting. In two experiments, stop-signal performance was examined in a psychological refractory period task, in which subjects inhibited one response while still executing the other. The results showed little evidence for the refractory effect in stop-signal reaction time, and stop-signal reaction time was similar in dual-task and single-task conditions, despite the fact that overt reaction times were significantly affected by dual-task interference. Therefore, the present study supports the claim that response inhibition does not suffer dual-task interference.     

Factors affecting occupational advice for speakers who do and do not stutter

Factors affecting perceptions of occupational suitability were examined for speakers who stutter and speakers who do not stutter. In Experiment 1, 58 adults who do not stutter heard one of two audio recordings (less severe stuttering, more severe stuttering) of a speaker who stuttered. Participants rated the speaker's communicative functioning, personal attributes, and suitability for 32 occupations, along with perceptions of the occupations' speaking demands and educational requirements. Perceived speaking demand strongly affected occupational suitability ratings at both levels of stuttering severity. In Experiment 2, 58 additional adults who do not stutter heard a recording of another adult in one of two conditions (fluent speech, pseudo-stuttering), and provided the same ratings as in Experiment 1. In the pseudo-stuttering condition, participants' perceptions of occupational speaking demand again had a strong effect on occupational suitability ratings. In the fluent condition, suitability ratings were affected primarily by perceived educational demand; perceived speaking demand was of secondary importance. Across all participants in Experiment 2, occupational suitability ratings were associated with ratings of the speaker's personal attributes and communicative functioning. In both experiments, speakers who stuttered received lower suitability ratings for high speaking demand occupations than for low speaking demand occupations. Ratings for many high speaking occupations, however, fell just below the midpoint of the occupational suitability scale, suggesting that participants viewed these occupations as less appropriate, but not necessarily inappropriate, for people who stutter. Overall, the findings support the hypothesis that people who stutter may face occupational stereotyping and/or role entrapment in work settings. EDUCATIONAL OBJECTIVES: At the end of this activity the reader will be able to (a) summarize main findings on research related to the work-related experiences of people who stutter, (b) describe factors that affect perceptions of which occupations are best suited for speakers who stutter and speakers who do not stutter, and (c) discuss how findings from the present study relate to previous findings on occupational advice for people who stutter.     

Caller characteristics, call contents, and types of assistance provided by caller sex and age group in a Canadian Inuit crisis line in Nunavut, 1991-2001

Analysis of calls made to a northern Canadian Inuit crisis line in the territory of Nunavut between 1991 and 2001 revealed that the majority of users were adult females who called to discuss problems primarily related to relationships and loneliness/boredom. Younger callers tended to make prank calls. The volunteer staff used mostly empathetic listening and suggestions. Referral recommendations made were primarily to social services. Although some callers experienced a language barrier, others found the service to be helpful. Results suggest that the crisis line was underused by young Inuit males who represent a group that are most in need of crisis intervention.     

Operationalizing the Assessment and Management of Violence Risk in the Short-term

Assessing risk of violence in the short term is crucial for managing and preventing violence, especially in institutions such as psychiatric units and prisons. Despite a lack of consensus on the definition of "short term", a number of recent tools and guidelines have been developed to aid short-term clinical decision-making. Whereas the supporting evidence for the new tools is impressive, limitations remain in terms of the focus on prediction, limited consideration of strengths, and poor integration with formulation and risk management. The Short-Term Assessment of Risk and Treatability (START) is a brief clinical guide for the dynamic assessment of risks, strengths and treatability. It focuses on short-term risks and the characteristics of the individual that, if changed, might lead to an increase or decrease in risk. The START has the potential to operationalize the structured professional judgment (SPJ) approach in order to inform the evaluation of multiple risk domains relevant to everyday psychiatric clinical practice. However, explicit guidance on integrating risk assessment, formulation and management is limited in the START and this paper describes the SPJ approach, reviews recent developments in approaches to risk, and considers how the START can be used to inform SPJ approaches and link risk assessment, formulation, and management.

Psychometric Evaluation of the Borderline Personality Disorder Severity Index-IV-Adolescent Version and Parent Version

The Borderline Personality Disorder Severity Index-IV-adolescent and parent versions (BPDSI-IV-ado/p) are DSM-IV based semi-structured interviews for the assessment of the severity of symptoms of borderline personality disorder (BPD) in adolescents. The present study evaluates the psychometric properties of the BPDSI-IV-ado/p. The interviews were administered to 122 adolescents, aged 14-19 years and their parents/caretakers who were referred to mental health centres for emotion regulation problems, and to 45 healthy controls. The interrater reliability and internal consistency of all nine subscales (following the nine BPD symptoms in DSM-IV) proved to be good to excellent. Discriminant, concurrent, and construct validity were satisfactory. Cut-off scores that optimize sensitivity and specificity were derived. Informant agreement between adolescents and parents/caretakers was modest. The results of this study suggest that the BPDSI-IV adolescent and parent versions are valid and reliable instruments for the assessment of BPD symptom severity in adolescents.     

Essential Elements of Genetic Cancer Risk Assessment, Counseling, and Testing: Updated Recommendations of the National Society of Genetic Counselors

Updated from their original publication in 2004, these cancer genetic counseling recommendations describe the medical, psychosocial, and ethical ramifications of counseling at-risk individuals through genetic cancer risk assessment with or without genetic testing. They were developed by members of the Practice Issues Subcommittee of the National Society of Genetic Counselors Familial Cancer Risk Counseling Special Interest Group. The information contained in this document is derived from extensive review of the current literature on cancer genetic risk assessment and counseling as well as the personal expertise of genetic counselors specializing in cancer genetics. The recommendations are intended to provide information about the process of genetic counseling and risk assessment for hereditary cancer disorders rather than specific information about individual syndromes. Essential components include the intake, cancer risk assessment, genetic testing for an inherited cancer syndrome, informed consent, disclosure of genetic test results, and psychosocial assessment. These recommendations should not be construed as dictating an exclusive course of management, nor does use of such recommendations guarantee a particular outcome. These recommendations do not displace a health care provider's professional judgment based on the clinical circumstances of a client.
