The Slip Induction Task: Creating a window into cognitive control failures

Regardless of age, education, or social status, we all experience moments where we ask ourselves, "what was I thinking?!?" Typically, we experience errors of this sort, or slips of action, during routine tasks that require a whole sequence of movements. However, most action slip research has focused on creating response conflict within single movements. The Slip Induction Task (SIT) is a step toward creating response conflict within truer to life action routines. As such, the SIT attempts to induce action slips in a well-learned movement routine through the occasional presentation of unexpected cues. We find that the SIT is able to reliably induce action slips, especially when the unexpected cue necessitates a movement to an unexpected target location. Furthermore, when participants are able to avoid an action slip, these changes in movement routine are accompanied by a cost in speed.     

Pantomime and imitation of limb gestures in relation to the severity of Alzheimer's disease

The present study was designed to investigate the relationship between performance of limb gestures and the severity of Alzheimer's disease (A.D.). Apraxia tends to occur at later stages of A.D., and the severity of apraxia has been shown to vary with the severity of A.D. dementia. Participants were 19 mild (including 9 with no cognitive impairment and 10 with mild impairment) and 18 moderate A.D. patients as well as 25 controls and they were asked to pantomime (P) or imitate (both concurrent (CI) and delayed (DI)), eight transitive gestures to assess praxis performance. Results indicated that the moderate patients performed less accurately than mild and non-impaired patients, and that across all groups, the imitation conditions were performed less accurately than pantomime, relative to controls. Correlational analyses revealed that MMSE scores were correlated with all three performance conditions suggesting that impaired praxis performance may relate to more global impairment. Finally, a frequency analysis was conducted to examine whether A.D. patients showed patterns of apraxia as described in Roy's model (1996). Results indicated that A.D. patients showed greatest impairment on pattern 7 (deficits in P, DI, and CI), reflecting late-stage gesture production, with a greater frequency of moderate patients exhibiting each apraxic pattern.     

Qualitative Study of Suicidality and Help-Seeking Behaviors in African American Adolescents

This qualitative study explores adolescents’ perceptions of help-seeking behaviors in the context of a hypothetical suicide crisis. Cauce and colleague’s (2002, Journal of Consulting and Clinical Psychology, 70, 44–55) model was used to examine help-seeking behaviors in 3 domains: problem recognition, decision to seek help, and selection of helpers. Forty-two church-going African American adolescents participated in 1 of 6 focus groups that discussed ways to help a hypothetically suicidal student in a vignette. Findings suggest that although the majority of youth had been exposed to a suicidal peer (76%), they were unsure of the seriousness of suicide as a problem in the African American community. The findings suggest that youth were less comfortable with formal interventions in school, religious institutions or traditional mental health settings. However, youth were open to community-based programs that could be located in school, church or community settings if helpers were: young adults, empathic listeners, non-judgmental, maintained confidentiality, and viewed as “natural helpers”. Implications for developing church-based suicide interventions are discussed. This study was supported by a K-01 Career Development Award from NIMH     

Suicide and African American teenagers: risk factors and coping mechanisms

In this study we investigated whether locus of control, hopelessness, and depression were primary risk factors for suicide ideation and attempts in African American youth, and whether congruency between locus of control and religious coping style reduced suicide risk. The sample consisted of 176 African American high school students (115 females; 61 males). Multiple and logistic regression were used to determine relationships among study variables. Depression was found to mediate the relationship between hopelessness and suicidal behaviors. External locus of control led to greater risk for hopelessness and depression, with a trend in the predicted direction for suicide attempts. Religious coping style alone was not always associated with reduction of risk of suicidal behaviors, yet some evidence suggests that congruency between locus of control and religious coping style reduces risk. Results provide additional support for suicide interventions to target depressive symptoms. Results also highlight the importance of examining the role of culturally salient variables such as fatalism and religious coping style when developing intervention programs for suicide.     

Relationship Between Religious Coping and Suicidal Behaviors Among African American Adolescents

This study investigated whether hopelessness and depression were risk factors for suicidal thoughts and behaviors in African American adolescents and looked at whether religious participation and religious coping protected these students from suicidality. Participants were 212 African American high school students (133 females, 79 males). The results of multiple and logistic regression analyses found that hopelessness and depression were risk factors for suicidal ideation and attempts. Religious coping style was significantly related to suicidal behaviors: Self-directed coping was related to increased hopelessness, depression, and suicide attempts, and collaborative coping was related to increased reasons for living. Gender differences were found in symptoms of depression, religious coping style and religious participation. Results provide additional support for suicide interventions to target hopelessness and depressive symptoms and highlight the importance of examining the role of culturally salient variables, such as religious participation and religious coping style, when developing intervention programs for suicide.     

Post-migration Education Among Recent Adult Immigrants to Canada

The present study examines post-migration educational investment by new immigrants to Canada from two perspectives. First, what are the factors that influence whether a new immigrant invests in post-migration education (PME)? Second, is investment in PME associated with improved earnings? The results indicate that younger immigrants from ??non-traditional?? source countries, who are already well educated, fluent in English or French, and worked in a professional or managerial occupation prior to migration are most likely to enroll in PME. But acceptance of previous work experience by Canadian employers lowers the likelihood of investing in PME. Family obligations also reduce the likelihood of participating in PME. Financial limitations are not found to affect participation in PME. The earnings effect of PME is dependent on the type of course undertaken. In the short term, job-related seminars lead to improved earnings growth, while post-secondary courses result in a period of deceased earnings growth. Policy implications are discussed.     

Developing suicide prevention programs for African American youth in African American churches

Suicide prevention programs for African American youth in African American churches may have broad appeal because: (1) the Black Church has a strong history of helping community members, regardless of church membership; (2) African Americans have the highest level of public and private religiousness; and (3) the church can help shape religious and cultural norms about mental health and help-seeking. The proposed gatekeeper model trains lay helpers and clergy to recognize the risk and protective factors for depression and suicide, to make referrals to the appropriate community mental health resources, and to deliver a community education curriculum. Potential barriers and suggestions for how to overcome these barriers are discussed.     

An Analysis of Thoughts,Behaviours, and Emotions in Daily Decision-Making

Cognitive theory and naturalistic decision-making models were utilized to examine the relationship between thoughts, behaviours, and emotions in daily decision-making. An experimental survey using vignettes examined the effects of investment of cognitive and behavioural effort in hypothetical vignettes on emotional responses to uncertain negative outcomes. For each vignette, this negative outcome was either surprising or distressing. Further, the type of uncertainty was an alteration, inclusion, or cancellation pertaining to the original vignette, yielding six conditions in the within-groups design. Participants (N = 335, 220 females) responded to each vignette by choosing a behavioural effort option (low or high), following which they elaborated the reason for their choice (high or low cognitive effort). They also responded to the predetermined negative outcome on an affective scale (emotional response). Results showed that (a) emotional responses to vignettes varied, based on the type of uncertainty in the scenario; (b) surprising outcomes elicited higher emotional distress; (c) behavioural effort positively predicted emotional distress when the type of uncertainty was alteration or inclusion; and (d) strategies involving high cognitive effort predicted investment of high behavioural effort in the vignette. Implications of examining behavioural, cognitive, and emotional processes leading to daily decisions are discussed in the context of coping with uncertainty.
