Cognitive change 5 years after coronary artery bypass surgery.

A longitudinal study of cognitive function after coronary artery bypass surgery examined 107 participants using 11 tests, preoperatively and at 6 days, 8 weeks, and 5 years after surgery. The overall neuropsychological (NP) change score declined at 6 days, showed some recovery at 8 weeks, and declined again at 5 years. The number of microemboli recorded during surgery, postoperative short-term cognitive change, and degree of recovery at 8 weeks were identified as predictors of change in NP score to 5 years. This suggests that even over a 5-year period, operative damage is detectable. Patients' vulnerability to short-term deterioration and resilience or ability to recover over a few weeks from operative cerebral insult are important processes of unknown mechanisms.     

Is there "feedback" during visual imagery? Evidence from a specificity of practice paradigm.

The specificity of practice hypothesis predicts the development of a sensorimotor representation specific to the afferent feedback available during skill acquisition (Proteau, 1992; Proteau, Marteniuk, Girouard, & Dugas, 1987). In the present investigation, we used the specificity of practice hypothesis to test whether skill acquisition through visual imagery would lead to the development of a sensory-specific movement representation similar to one resulting from actual practice. To accomplish this objective, participants practiced walking a 12-m linear path in one of three practice conditions, full-vision (FV), no-vision (NV), or visual imagery (VI), for either 10 or 100 trials. Knowledge of spatial and/or temporal results (KR) was provided to participants following each trial during this phase. Following acquisition, participants completed 10 NV trials without KR. An analysis of root-mean-squared-error (RMSE) indicated NV participants were more accurate than both FV and VI participants in the transfer condition. We believe the equivalence in transfer RMSE between FV and VI suggests that there are similarities between the movement representations attained by FV and VI practice.     

Spiritual Maturity and Social Support in a National Study of a Male Religious Order

This national study analyzed the relationship of spiritual maturity and valued relationships with social support and life satisfaction using a random sample of male religious from one Roman Catholic order (N = 251). Four measures were used: (a) NEO-Five Factor Inventory (NEO-FFI; Costa & McCrae, 1992), (b) Spiritual Maturity Index (SMI; Ellison, 1983), (c) Social Support Appraisals Scale (SS-A; Vaux, et al., 1986), and (d) Satisfaction With Life Scale (SWLS; Diener, Emmons, Larsen, & Griffin, 1985). Hierarchical regression results showed that Spiritual Maturity was a significant predictor of Perceived Social Support (F (1, 237) = 20.662, p ≤ .001) and Life Satisfaction (F(1, 237) = 13.205, p ≤ .001). The study also showed that valued relationships inside (versus outside) the order predicted Life Satisfaction (F(1, 236) = 4.722, p ≤ .05). These findings demonstrate the importance of spiritual development and peer relationships as a way of enhancing vocational stability and satisfaction in male religious.     

Concurrent cognitive task modulates coordination dynamics

Does a concurrent cognitive task affect the dynamics of bimanual rhythmic coordination? In‐phase coordination was performed under manipulations of phase detuning and movement frequency and either singly or in combination with an arithmetic task. Predicted direction‐specific shifts in stable relative phase from 0° due to detuning and movement frequency were amplified by the cognitive task. Nonlinear cross‐recurrence analysis suggested that this cognitive influence on the locations of the stable points or attractors of coordination entailed a magnification of attractor noise without a reduction in attractor strength. An approximation to these findings was achieved through parameter changes in a motion equation in relative phase. Results are discussed in terms of dual‐task performance as limited resources, dynamics rather than chronometrics, and reparameterization rather than degradation.     

Attentional mechanisms linking rejection to hostile reactivity: the role of "hot" versus "cool" focus

Drawing on the hot–cool systems analysis of self–regulation, we examined whether attentional focus mediates the negativity of cognitive–affective reactions to interpersonal rejection. The hypothesis was that whereas a hot, arousing focus to representing rejection experiences should increase anger–hostility, accessing the cool system through distraction and distancing should attenuate such responses. Participants imagined an autobiographical rejection experience, focusing either on their physiological and emotional reactions (hot focus) or on the physical setting of the experience (cool focus). Participants in a third condition received no specific attentional instructions. Both implicit and explicit measures showed that hostile thoughts and feelings were attenuated in the cool–focus compared with the hot–focus condition. The findings support the adaptive value of activating a cooling strategy under hot, arousing conditions that otherwise elicit automatic, hot–system responses.     

Tactical differences in coping with rejection sensitivity: the role of prevention pride

Prevention pride reflects a person's subjective history of success in preventing negative outcomes, leading to a strategic avoidance of errors of commission (e.g., explicit mistakes) in new situations. Two studies examined the impact of prevention pride on the strategies that highly rejection sensitive (HRS) people use to cope with the anxiety of anticipated rejection and the negative feelings elicited by perceived rejection. It was hypothesized that prevention pride orientation would lead HRS people toward covert and passive rather than overt and active forms of negative coping. Results indicated that HRS individuals who were also high in prevention pride reported increased use of self-silencing, presumably to prevent rejection. When rejection was perceived, however, they expressed hostility passively, by reducing positive behavior (e.g., withdrawing love and support) while inhibiting direct, active acts of hostility (e.g., yelling).     

Racial differences in self-disclosure of suicidal ideation and reasons for living: implications for training

Racial differences in suicidal self-disclosure and reasons for living were investigated in 2 separate studies. In Study 1, a random sample of archival client and therapist intake data from a university counseling center for 1 year was examined, and results indicate that ethnic minority clients do not self-disclose suicidal ideation as readily as their nonethnic minority peers. In addition, a significantly higher number of ethnic minority clients were deemed "hidden ideators" because their suicidal ideation only became evident when a counselor performed a suicide risk assessment. Only 1 of the 36 ethnic minority clients with suicidal ideation in the sample voluntarily self-disclosed this ideation at intake without an assessment by the therapist. Study 2 used the Reasons for Living Inventory (RFL) and compared African American and European American college students from an introductory psychology course. The RFL is a useful instrument to compare potential race differences in reasons people report for choosing not to kill themselves, because it does not require respondents to self-disclose (or to have) current suicidal ideation. The results from Study 2 indicate European Americans report fewer reasons for choosing not to kill themselves than their African American peers and that African Americans scored significantly higher than European Americans on the moral objections and survival and coping beliefs subscales of the RFL. Implications for training counselors in suicide risk assessment, prevention, and treatment with ethnic minorities are discussed.     

Children of depressed parents: an integrative review

This article reviews the various literatures on the adjustment of children of depressed parents, difficulties in parenting and parent-child interaction in these families, and contextual factors that may play a role in child adjustment and parent depression. First, issues arising from the recurrent, episodic, heterogeneous nature of depression are discussed. Second, studies on the adjustment of children with a depressed parent are summarized. Early studies that used depressed parents as controls for schizophrenic parents found equivalent risk for child disturbance. Subsequent studies using better-defined samples of depressed parents found that these children were at risk for a full range of adjustment problems and at specific risk for clinical depression. Third, the parenting difficulties of depressed parents are described and explanatory models of child adjustment problems are outlined. Contextual factors, particularly marital distress, remain viable alternative explanations for both child and parenting problems. Fourth, important gaps in the literature are identified, and a consistent, if unintentional, "mother-bashing" quality in the existing literature is noted. Given the limitations in knowledge, large-scale, long-term, longitudinal studies would be premature at this time.
