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 Parents Matter! Program Interventions: Content and the Facilitation Process

The Parents Matter! Program (PMP) has developed three interventions for parents of 4th and 5th grade African-American children (9–12 years old). The overarching goal of all three interventions is to provide parents with knowledge, skills, and support for enhancing their efforts to raise healthy children. The interventions are: (1) Enhanced Communication and Parenting (five 2 -hour sessions), (2) Brief Communication and Parenting (single 2 -hour session), and (3) General Health (single 2 -hour session). This article discusses the development of these interventions, presents an overview of the content of each intervention, and discusses issues related to the facilitation/presentation of these interventions.     

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.     

The distinctiveness of emotion concepts: a comparison between emotion, abstract, and concrete words

Are the concepts represented by emotion words different from abstract words in memory? We examined the distinct characteristics of emotion concepts in 3 separate experiments. The first demonstrated that emotion words are better recalled than both concrete and abstract words in a free recall task. In the second experiment, ratings of abstract, concrete, and emotion words were compared on concreteness, imageability, and context availability scales. Results revealed a difference between all 3 word types on each of the 3 scales. The third experiment investigated priming in a lexical decision task for homogeneous (abstract-abstract and emotion-emotion) and heterogeneous (abstract-emotion and emotion-abstract) associated word pairs. Priming occurred only for the homogeneous and heterogeneous abstract-emotion word pair conditions. Possible explanations for these findings are discussed in terms of the circumplex, hierarchical, and semantic activation models. The results are most consistent with the predictions of the semantic activation model.     

A field study of frame-of-reference effects on personality test validity

As part of a test validation study at a major U.S.-based airline, the authors tested the effects of providing an "at work" frame-of-reference on the validity of the NEO Five-Factor Inventory among a sample of customer service supervisors (N = 206). Frame-of-reference moderated the validity of the Extraversion and Openness to Experience subscales after controlling for cognitive ability. In addition, the frame-of-reference personality test showed incremental validity over cognitive ability (deltaR2 = .16), but the standard personality test did not (deltaR2 = .05). The authors' discussion focuses on implications for personality theory and research and on implications for increasing the validity of personality tests in organizational settings.     

Developments in long-term explicit memory late in the first year of life: behavioral and electrophysiological indices

Coincident with developments in the temporal-cortical explicit memory network, long-term recall abilities are newly emergent late in the first year of human life. We recorded event-related potentials (ERPs) in 9-month-olds as an index of the integrity of the neural substrate underlying a task thought to reflect explicit memory, namely, deferred imitation. ERP measures of recognition memory 1 week after unique laboratory experiences predicted whether and how much infants recalled of the experiences 1 month later. The findings further imply that memory storage and consolidation processes are a major source of variability in long-term recall memory late in the first year of life.     

Reexposure breeds recall: effects of experience on 9-month-olds' ordered recall

On the basis of three experiences, 9-month-olds recall specific events after one month. We tested whether multiple experiences are necessary, or merely facilitative, of 9-month-olds' long-term recall. In two experiments, using deferred imitation, infants were exposed to multi-step sequences either one time, two times, or three times prior to a one-month delay. In Experiment 1, regardless of the number of experiences, infants did not demonstrate recall. In Experiment 2, infants were tested on and reexposed to the events after one week; recall was tested again one month later. Performance after 1 week in Experiment 2 was greater than performance after one month in Experiment 1. Moreover, presumably as a function of reexposure after one week, infants recalled the individual actions of the events one month later. Infants in the three-experience condition also evidenced ordered recall after one month. Implications for the developmental status of the neural substrate supporting long-term recall are discussed.
