An evaluation of the cross‐national generalizability of organizational commitment

Using data from two large multinational samples, this research sought to contribute to our knowledge of international organizational behaviour by examining the cross‐national generalizability of organizational commitment. Sample 1 included employees of 10 subsidiaries of a large multinational organization, whereas Sample 2 relied on data collected in 25 nations in the context of a large opinion survey. Results in both samples supported the expectation that measures of commitment would be more susceptible to measurement non‐equivalence than measures of job satisfaction. Differences in relationships between commitment and satisfaction across countries were observed in both samples, as were differences in mean commitment levels. Nation‐level individualism/collectivism (I/C) failed to account for the observed differences, however, suggesting that commitment and I/C are largely independent, despite theoretical arguments to the contrary. Results of the study suggest that despite some cross‐national variation, differences in commitment across national boundaries are small and empirically unrelated to I/C.     

Neural correlates of subliminal and supraliminal letter processing--an event-related fMRI study

One problem of interpreting research on subconscious processing is the possibility that participants are weakly conscious of the stimuli. Here, we compared the fMRI BOLD response in healthy adults to clearly visible single letters (supraliminal presentation) with the response to letters presented in the absence of any behavioural evidence of visibility (subliminal presentation). No letter catch trials served as a control condition. Forced-choice responses did not differ from chance when letter-to-background contrast was low, whereas they were almost 100% correct when contrast was high. A comparison of fMRI BOLD signals for supraliminal and subliminal letters with the control trials revealed a signal increase in left BA 37 (fusiform gyrus). Comparison of supraliminal with subliminal letters showed a significant increase in the right inferior frontal gyrus (BA 44, partly extending to BA 9 and BA 45, as well as BA 46). Finally, a comparison of subliminal with supraliminal letters showed increases in the left middle temporal gyrus (BA 21) and the right extrastriate cortex (BA 19).     

Outcomes from Multisystemic Therapy in a Statewide System of Care

We examined client outcomes from the implementation of Multisystemic Therapy (MST) in a statewide child and adolescent mental health system. Specifically, we examined (1) the validity of therapist-rated MST outcome measures by comparing them to ratings of functional impairment and level of service needs by CAMHD care coordinators, who provide case management and care coordination services, (2) potential client and service predictors of therapist-rated outcomes, and (3) improvement in youth functioning around the time of entry to and exit from MST compared with rates of improvement reported in randomized controlled trials (RCTs) by the developers of MST. Results suggested that therapist-rated MST outcomes were valid indicators of treatment success. Similar to other findings in the MST literature, few client or service characteristics predicted these outcomes. Finally, although MST entry–exit effect sizes were lower than the mean derived from RCTs published by the developers, they were within the 95% confidence interval. Together, these findings support the implementation of MST in complex systems of care with continued attention to quality assurance and ongoing use of data for evaluation.     

Decision noise may mask criterion shifts: Reply to Balakrishnan and MacDonald (2008)

J. D. Balakrishnan and J. A. MacDonald (2008) argue that RTbased measures of signal detection processes provide evidence against signal detection theory’s notion of a flexible decision criterion. They argue that this evidence is immune to the alternative explanation proposed by S. T. Mueller and C. T. Weidemann (2008), that decision noise may mask criterion shifts. We show that noise in response times can produce the same effects as are produced by noise in confidence ratings. Given these results, the evidence is not sufficient to categorically reject the notion of a flexible response policy implemented through shifts in a decision criterion. nt]mis|This research was supported in part by a postdoctoral fellowship to C.T.W. from the German Academic Exchange Service (DAAD).     

The self-protective and undermining effects of attributional ambiguity

Two experiments assessed the self-protective and undermining effects of attributional ambiguity. Both studies utilized immersive virtual environment technology to achieve otherwise difficult manipulations of stigma. In Experiment 1, White and Latino participants were either stigmatized (represented as Latino) or not (represented as White) and given negative leadership performance feedback. Afterwards, stigmatized participants reported higher well-being and attributed negative feedback more to discrimination than nonstigmatized participants. In Experiment 2, Latinos represented veridically showed self-protective effects after receiving negative leadership feedback. Additionally, this experiment revealed undermining effects of attributional ambiguity such that those participants represented as Latino discounted positive feedback and reported lower well-being. Thus, attributional ambiguity of stigmatized individuals (real or induced) buffered well-being in the face of negative feedback but undermined the well-being effects of positive feedback.     

Psychosocial mediation of religious coping styles: a study of short-term psychological distress following cardiac surgery

Although religiousness and religious coping styles are well-documented predictors of well-being, research on the mechanisms through which religious coping styles operate is sparse. This prospective study examined religious coping styles, hope, and social support as pathways of the influence of general religiousness (religious importance and involvement) on the reduced postoperative psychological distress of 309 cardiac patients. Results of structural equation modeling indicated that controlling for preoperative distress, gender, and education, religiousness contributed to positive religious coping, which in turn was associated with less distress via a path fully mediated by the secular factors of social support and hope. Furthermore, negative religious coping styles, although correlated at the bivariate level with preoperative distress but not with religiousness, were associated both directly and indirectly with greater post-operative distress via the same mediators.     

Prenatal Diagnosis for Inherited Deafness—What is the Potential Demand?

Genetic testing for inherited deafness is now available within some genetics centres. This study used a structured questionnaire to assess the potential uptake of prenatal diagnosis (PND) for inherited deafness, and document the opinions of deaf and hearing individuals toward PND and termination of pregnancy (TOP) for hearing status. Participants were self-selected from the whole of the UK, of whom 644 were deaf, 143 were hard of hearing or deafened, and 527 were hearing individuals who had either a deaf parent or child. The results showed that 21% of deaf, 39% of hard of hearing and deafened, and 49% of hearing participants said they would consider PND for deafness. Six percent of deaf, 11% of hard of hearing and deafened, and 16% of hearing participants said they would consider a TOP if the fetus was found to be deaf. Two percent of deaf participants said they would prefer to have deaf children and would consider a TOP if the fetus was found to be hearing.     

Weight beliefs and messages: Mindsets predict body‐shame and anti‐fat attitudes via attributions

In two samples (N = 247, N = 291), we examined the link between beliefs and messages about the changeable (incremental theory) vs. fixed (entity theory) nature of weight, attributions for weight, and body shame. We recruited participants using online sampling, employing a correlational design in Study 1 and an experimental design in Study 2. Across both studies, we found evidence for the stigma‐asymmetry effect—incremental, relative to entity beliefs/messages of weight predicted both (a) stronger onset responsibility attributions, indirectly increasing body shame and (b) stronger offset efficacy attributions, indirectly decreasing body shame. Study 2 replicated the stigma‐asymmetry effect with anti‐fat attitudes. We discuss implications for public health obesity messages with the goal of reducing stigma.     

Influence of Motor Cortex Stimulation During Motor Training on Neuroplasticity as a Potential Therapeutic Intervention

Rehabilitation options to promote neuroplasticity may be enhanced when patients are engaged in motor practice during repetitive transcranial magnetic stimulation (rTMS). Twelve participants completed 3 separate sessions: motor practice, motor practice with rTMS, and rTMS only: motor practice consisted of 30 isometric contractions and subthreshold rTMS was 30, 3-s trains at 10 Hz. Assessments included the Box and Block Test (BBT), force steadiness (10% of the maximum voluntary contraction), and TMS (cortical excitability, intracortical inhibition, and intracortical facilitation). Participants significantly increased BBT scores following the combined condition. Force steadiness improved after all 3 conditions (p < .05). TMS outcomes depended on intervention condition with significant increases in facilitation following the motor practice plus rTMS condition. All interventions influenced motor control, yet are likely modulated differently when combining motor practice plus rTMS. These results help guide the clinical utility of rTMS as an intervention to influence motor control.
