What Factors Influence Therapy Drop Out?

Are there systematic factors that predict client drop out in marriage and family therapy? Based on our review of literature we investigated the influence on drop out of personality characteristics such as hostility, anxiety, satisfaction with life, and self-esteem. We also investigated several demographic variables. The following variables were statistically significant predictors of client drop out: modality of treatment, marital status, occupation, income, and previous therapy experience.     

Does spatial learning ability of common voles (<Emphasis Type="Italic">Microtus arvalis</Emphasis>) and bank voles (<Emphasis Type="Italic">Myodes glareolus</Emphasis>) constrain foraging efficiency?

Place learning abilities represent adaptations that contribute also to foraging efficiency under given spatio-temporal conditions. We investigated if this ability in turn constrains decision making in two sympatric vole species: while the herbivorous common vole (Microtus arvalis) feeds on spatio-temporally predictable food resources (e.g. roots, tubers and shoots of plant tubers), the omnivorous bank vole (Myodes glareolus) additionally subsists on temporally unpredictable food resources (e.g. insects and seeds). Here, we compare the spatial reference memory and working memory of the two species. In an automated operant home cage with eight water places, female voles either had to learn the fixed position of non-depletable places (reference memory task) or learn and avoid previously visited water places depleted in a single visit (win-shift task). In the reference memory task, Microtus females required significantly more choices to find all water places, initially performed slightly worse than Myodes females, and displayed slightly lower asymptotic performance. Both species were highly similar in new learning of the same task. In the more complex win-shift task, asymptotic performance was significantly lower in Microtus (72% correct) than in Myodes (79%). Our results suggest that both vole species resemble each other in their efficiency to exploit habitats with low spatio-temporal complexity but may differ in their efficiency at exploiting habitats with temporally changing spatial food distributions. The results imply that spatial ability adjusted to specific food distributions may impair flexible use of habitats that differ in their food distribution and therefore, decrease a species’ chances of survival in highly dynamic environments.     

Phases of Organ Integration and Conflict in a Transplant Recipient: A Longitudinal Study Using a Diary

In this paper the results from a research project on self-perception and psychological processing following transplantation of solid organs are presented. A diary at the individual case level was introduced to generate a longitudinal analysis. In the following paper we describe an evaluation of the entries of a single patient following a living donor kidney transplant. Conflicts in the relationship between the transplant recipient and the donor, who is also his wife, are clearly evident, and these are interpreted as incorporation conflicts in light of current psychoanalytic theory.     

Family climate of routine asthma care: associating perceived burden and mother-child interaction patterns to child well-being

This preliminary report links the literatures on family asthma management practices and on the characteristics of family interaction patterns thought to influence children's adjustment to a chronic physical illness. Specifically, this study of 60 families with a child with asthma examined the extent to which perceived burden of routine asthma care affected child mental health via its influence on parent-child interaction patterns. Mothers completed a measure of asthma management routine burden, mother and child were observed in a 15-minute interaction task, and children completed measures of child anxiety and asthma quality of life (QOL). Perceived routine burden significantly predicted child anxiety and QOL through its effect on mother-child rejection/criticism. The same pattern did not hold for mother intrusiveness/control. The results are discussed in terms of how overall family climate and regulation of routines affects child well-being. Implications for clinical practice and limitations of the study are provided.     

Developmental changes in depressive cognitions: a longitudinal evaluation of the Cognitive Triad Inventory for Children

As part of a longitudinal study, the Cognitive Triad Inventory for Children (CTI-C; N. J. Kaslow, K. D. Stark, B. Printz, R. Livingston, & S. L. Tsai, 1992) as well as other measures of cognitive style and depressive symptoms were administered annually to 3 cohorts of children starting in Grades 2, 4, and 6. Developmentally based analyses revealed 4 things: (a) The factor structure of the CTI-C changed over the course of middle childhood and then stabilized in early adolescence; (b) the CTI-C correlated significantly with measures of depression, self-perceived competence, self-worth, perceived controllability, and perceived contingency, but not with measures of attributional style; (c) 1-year stability correlations increased substantially from Grade 2 to Grade 8; and (d) the CTI-C did not generally predict self-reported depressive symptoms 1 year later. Implications emerge regarding developmental changes in the structure of children's depressive cognitions.     

Perceptual saliency of points along the contour of everyday objects: a large-scale study

The aim of this large-scale study was to find out which points along the contour of a shape are most salient and why. Many subjects (N=161) were asked to mark salient points on contour stimuli, derived from a large set of line drawings of everyday objects (N=260). The database of more than 200,000 marked points was analyzed extensively to test the hypothesis, first formulated by Attneave (1954), that curvature extrema are most salient. This hypothesis was confirmed by the data: Highly salient points are usually very close to strong curvature extrema (positive maxima and negative minima). However, perceptual saliency of points along the contour is determined by more factors than just local absolute curvature. This was confirmed by an extensive correlational analysis of perceptual saliency in relation to ten different stimulus factors. A point is more salient when the two line segments connecting it with its two neighboring salient points make a sharp turning angle and when the 2-D part defined by the triplet of salient points is less compact and sticks out more.     

Consumer credit card use: the roles of creditor disclosure and anticipated emotion

In response to federal legislative reform aimed, in part, at reducing consumer bankruptcy filings, the authors conducted 2 experiments examining the role of affect in purchasing behavior. In Experiment 1, they examined consumer debtors, and in Experiment 2, they examined nondebtors. In both experiments, they investigated purchasing decisions made during a simulated online shopping trip, with some participants receiving standard disclosures of interest rates and money owed and with other participants receiving information under the new enhanced disclosure regulations. Results demonstrated support for the influence of anticipated affect in credit card use among both debtors and nondebtors and indicated that anticipated emotion may moderate the impact of the enhanced disclosure regulations.     

Explicating the Openness to Experience Construct and its Subdimensions and Facets in a Work Setting

Recent meta‐analyses (e.g. Barrick, Mount, & Judge, 2001 ) found openness to experience, a factor in the five‐factor model of personality, to be uncorrelated with job performance. We argue that, among others, insignificant validity is due to the broad and heterogeneous nature of the construct. In line with our hypotheses, we found internal structure of openness to be multidimensional. Further analyses on subdimensional and facet level revealed large differences in criterion‐ and construct‐related validity. It could be demonstrated that a subdimension labeled epistemic curiosity and, especially, the facet openness to ideas, which includes aspects like curiosity, flexibility, willingness to learn, and creativity, are highly relevant for work‐related criteria and so far understudied in organizational research.     

When are social judgments made? Evidence for the spontaneousness of trait inferences

Do people make trait inferences, even without intentions or instructions, at the encoding stage of processing behavioral information? Tulving's encoding specificity paradigm (Tulving & Thomson, 1973) was adapted for two recall experiments. Under memory instructions only, subjects read sentences describing people performing actions that implied traits. Later, subjects recalled each sentence under one of three cuing conditions: (a) a dispositional cue (e.g., generous), (b) a strong, nondispositional semantic associate to an important sentence word; or (c) no cue. Recall was best when cued by the disposition words. Subjects were unaware of having made trait inferences. Interpreted in terms of encoding specificity, these results indicate that subjects unintentionally made trait inferences at encoding. This suggests that attributions may be made spontaneously, as part of the routine comprehension of social events.     

Biomechanical motor patterns in normal walking

Motor patterns in normal human gait are evident in several biomechanical and EMG analyses over the stride period. Some of these patterns are invariant over the stride period with changes of cadence, whole others are closely correlated with speed changes. The findings for slow, natural, and fast walking are summarized: 1. Joint angle patterns over the stride period are quite invariant, and do not change with cadence; 2. Moment of force patterns at the ankle are least variable and quite consistent at all speeds; 3. A recently defined support moment is quite consistent at all speeds. 4. Moments at the knee and hip are highly variable at all cadences but decrease their variability as cadence increases; 5. Mechanical power patterns at all joints show consistent timing over the stride period; 6. EMG profiles of 5 muscles show consistent timing over the stride, but the amplitude increases as walking speed increases. Arguments are presented to support the concept that walking speed is largely controlled by gain and that the timing of the motor patterns, which is extremely tightly synchronized with the anatomical position, is under major afferent control.
