The Use of Multitrait–Multimethod Data for Detecting Nonlinear Relationships: The Case of Psychological Climate and Job Satisfaction

Previous monomethod research has found mixed support for nonlinear effects between certain job characteristics (e.g., job autonomy, job complexity) and outcome variables (e.g., job performance). We hypothesized that these weak nonlinear findings may be due to the prevalence of monomethod research that can lead to a lack of complete measurement and/or introduce common methods variance, either of which may mask the true shape of relationships. Using hierarchical regression analyses and a multitrait–multimethod (MTMM) research design, we found strikingly different results between monomethod and MTMM data when considering the relationships between three psychological climate variables and job satisfaction. While the monomethod results mirrored earlier inconclusive findings, the MTMM data indicated that nonlinear equations explained significantly more of the relationship between all three climate dimensions and job satisfaction. These results suggest that the use of MTMM data allows one to more effectively test for nonlinear effects. Furthermore, these nonlinear results suggest that the format of employee questionnaires should probably change from asking how much an employee has of certain constructs to asking does the employee want more or less of these constructs.     

From majority to minority and vice versa: the asymmetrical effects of losing and gaining majority position within a group

Two studies examined the effects of stable, partially changed, and completely changed majority and minority positions within a group on perception and evaluation of the group. It was hypothesized that loss of majority position (majority-to-minority change) would have stronger effects than gain of majority position (minority-to-majority change). The hypothesized asymmetrical effect was demonstrated in that loss of majority position decreased perception of group-self similarity, group attraction, and expectations for positive interactions with the group, whereas a corresponding gain of position did not increase them. Thus immediately following changes, the group is especially fragile because disintegrative forces created by the loss of majority position are stronger than integrative forces created by the gain of majority position.     

Cocaine exposure is associated with subtle compromises of infants' and mothers' social-emotional behavior and dyadic features of their interaction in the face-to-face still-face paradigm

Prenatal cocaine and opiate exposure are thought to subtly compromise social and emotional development. The authors observed a large sample of 236 cocaine-exposed and 459 nonexposed infants (49 were opiate exposed and 646 nonexposed) with their mothers in the face-to-face still-face paradigm. Infant and maternal behaviors were microanalytically coded. No opiate-exposure effects were detected. However, mothers of cocaine-exposed infants showed more negative engagement than other mothers. The cocaine-exposed dyads also showed higher overall levels of mismatched engagement states than other dyads, including more negative engagement when the infants were in states of neutral engagement. Infants exposed to heavier levels of cocaine showed more passive-withdrawn negative engagement and engaged in more negative affective matching with their mothers than other infants. Although effect sizes were small, cocaine exposure, especially heavy cocaine exposure, was associated with subtly negative interchanges, which may have a cumulative impact on infants' later development and their relationships with their mothers.     

Crystallization of desire and crystallization of discontent in narratives of life-changing decisions

Two studies of adults examined personal narratives of life-changing decisions in relation to personality and well-being. Participants whose decision narratives emphasized a crystallization of desire (i.e., approaching a desired future) rather than a crystallization of discontent (i.e., escaping an undesired past; Baumeister, 1991, 1994) reported higher well-being, fewer avoidance strivings, lower Neuroticism (in Study 1 only), and better decision outcomes (in Study 2). However, neither strivings, traits, nor outcomes accounted for the relationship between crystallization of desire and well-being. The discussion considers the roles of life-changing decisions and personal narratives in research on personality, well-being, and positive personal development.     

Developments in declarative memory

The second year of life is marked by changes in the robustness of recall memory. Both retrieval and storage processes have been implicated as the major source of age-related improvements in recall. Children 13 to 20 months of age were matched for levels of learning of laboratory events (thereby eliminating encoding as a source of developmental difference) and tested for recall after delays as long as 6 months. In Experiment 1, 16-month-olds evidenced less loss of information and more relearning than 13-month-olds. In Experiment 2, 20-month-olds evidenced less loss of information and more relearning than 16-month-olds. Patterns of performance across test trials and in relearning implicate a decline in susceptibility to storage failure as the primary source of the observed developmental trend.     

Bodies and their parts

How do we think about the space of bodies? Several accounts of mental representations of bodies were addressed in body part verification tasks. Animagery account predicts shorter times to larger parts (e.g., back < hand). Apart distinctiveness account predicts shorter times to more discontinuous parts (e.g., arm < chest). Apart significance account predicts shorter times to parts that are perceptually distinct and functionally important (e.g., head < back). Because distinctiveness and significance are correlated, the latter two accounts are difficult to distinguish. Both name-body and body-body comparisons were investigated in four experiments. In all, larger parts were verified more slowly than smaller ones, eliminating the imagery/size account. Despite the correlation between distinctiveness and significance, the data suggest that when comparisons are perceptual (body-body), part distinctiveness is the best predictor, and when explicit or implicit naming is involved, part significance is the best predictor. Naming seems to activate the functional aspects of bodies.     

Age,culture, and loneliness among czechs and canadians

The present study examined the influence of cultural background on the experience of loneliness. One hundred and ninety-four Canadians and 209 participants from the Czech Republic formed the subject pool. Rather than compare the two populations and disregard the within and between age differences, the cultural groups were divided into age subgroups. These were young adults (18–30 years old), adults (31–59) and seniors (60–89). They answered a 30-item yes/no questionnaire. The questionnaire is composed of five subscales, namely. Emotional Distress, Social Inadequacy and Alienation, Growth and Discovery, Interpersonal Isolation, and Self-Alienation. Results indicated that overall, the cultural groups differed in their experiences of loneliness. Further, when each age group was compared across the two cultures, it was evident that the age groups scored significantly differently from its counterparts in the other culture. Scores of different age groups within cultures were also examined. This study was supported by York University's Grant # 496055     

The integration of continuous and discrete latent variable models: potential problems and promising opportunities

Structural equation mixture modeling (SEMM) integrates continuous and discrete latent variable models. Drawing on prior research on the relationships between continuous and discrete latent variable models, the authors identify 3 conditions that may lead to the estimation of spurious latent classes in SEMM: misspecification of the structural model, nonnormal continuous measures, and nonlinear relationships among observed and/or latent variables. When the objective of a SEMM analysis is the identification of latent classes, these conditions should be considered as alternative hypotheses and results should be interpreted cautiously. However, armed with greater knowledge about the estimation of SEMMs in practice, researchers can exploit the flexibility of the model to gain a fuller understanding of the phenomenon under study.     

In Search of a Neuronal Signature of Consciousness – Facts,Hypotheses and Proposals

Evolution leads to more and more complex structures, e.g., molecules, cells and organisms. By means of such structures elementary dynamic bio-electrical fields originate in single cells. They further develop into neurons with neuronal fields, and these combine and integrate in brains into global neuro-electrical fields (NEF) as a medium for the fast representation of outer stimuli. The present hypothesis proposes a specific state of the global NEF in brains as the signature of consciousness. This NEF changes periodically between two states, a de- and a hyperpolarized brain state, and these in turn are paralleled intimately by transitions between consciousness and unconsciousness. In the hyperpolarized state the elementary neuronal fields are enslaved and synchronized by strong oscillations, and under these conditions the NEF is of low information capacity. In the depolarized state, however, the elementary fields are freed to self-organize and superimpose into an integrated NEF rich in information. In this condition the NEF acquires a qualitatively new state variable: consciousness. This new variable is no longer physically measurable; it can only be perceived by introspection.     

Interpersonal problems and outcome in outpatient psychotherapy: findings from a long-term longitudinal study in Germany

We used a comprehensive longitudinal data set from Germany to examine trajectories of symptom distress depending on interpersonal problems at study intake measured via the Inventory of Interpersonal Problems-64 (IIP-64; Horowitz, Strau, & Kordy, 1994). Participants (N=622) underwent mid- or long-term outpatient psychotherapy (either psychodynamically oriented psychotherapy, cognitive behavioral therapy, or analytic psychotherapy). Data comprises up to 5 assessments during a 2-year period and was analyzed via hierarchical linear modeling. In the analytic psychotherapy subgroup, initial symptom level was higher in submissive patients. Initial interpersonal problems were not predictive of the rate of symptom change during therapy. Only in psychodynamic treatments, low affiliation positively affected treatment outcome. Interpersonal problems at intake were not related to the number of utilized sessions and utilization rate across treatment subgroups. We discuss the findings and outline future research topics.
