Recovery opportunities,work–home conflict,and emotional exhaustion among hematologists and oncologists in private practice

Hematologists and oncologists in private practice play a central role in the care provided for cancer patients. The present study analyzes stress and relaxation aspects in the work of hematologists and oncologists in private practice in Germany in relation to emotional exhaustion, as a core dimension of burnout syndrome. The study focuses on the opportunities for internal recovery using breaks and time out during the working day, the frequency of working on weekends and on vacation, and the physician’s work–home and home–work conflict. Postulated associations between the constructs were analyzed using a structural equation model. If work leads to conflicts in private life (work–home conflict), it is associated with greater emotional exhaustion. Working frequently at the weekend is associated with greater work–home conflict and indirectly with greater emotional exhaustion. By contrast, the availability of opportunities to relax and recover during the working day is associated with less work–home conflict and indirectly with less emotional exhaustion. These results underline the importance of internal recovery opportunities during the working day and a successful interplay between working and private life for the health of outpatient hematologists and oncologists.     

Cognitive and emotional demands of black humour processing: the role of intelligence,aggressiveness and mood

Humour processing is a complex information-processing task that is dependent on cognitive and emotional aspects which presumably influence frame-shifting and conceptual blending, mental operations that underlie humour processing. The aim of the current study was to find distinctive groups of subjects with respect to black humour processing, intellectual capacities, mood disturbance and aggressiveness. A total of 156 adults rated black humour cartoons and conducted measurements of verbal and nonverbal intelligence, mood disturbance and aggressiveness. Cluster analysis yields three groups comprising following properties: (1) moderate black humour preference and moderate comprehension; average nonverbal and verbal intelligence; low mood disturbance and moderate aggressiveness; (2) low black humour preference and moderate comprehension; average nonverbal and verbal intelligence, high mood disturbance and high aggressiveness; and (3) high black humour preference and high comprehension; high nonverbal and verbal intelligence; no mood disturbance and low aggressiveness. Age and gender do not differ significantly, differences in education level can be found. Black humour preference and comprehension are positively associated with higher verbal and nonverbal intelligence as well as higher levels of education. Emotional instability and higher aggressiveness apparently lead to decreased levels of pleasure when dealing with black humour. These results support the hypothesis that humour processing involves cognitive as well as affective components and suggest that these variables influence the execution of frame-shifting and conceptual blending in the course of humour processing.     

Clinicians' Observations of Family Interactions in the Reunification Process: The Parent Child Checklist

The present article employed a sample of 365 families of children in foster care to conduct a validation test of a newly developed instrument, the Parent Child Checklist (PCC). The PCC is a 54-item direct observation measure assessing parent–child interactions in the context of a family session. The PCC was developed to support the effective implementation of an evidence-based intervention, Parent Management Training-Oregon model, in the Kansas child welfare system. The PCC was designed to capture two scales of child behavior (prosocial and problem behavior) and five parenting domains (encouragement, positive involvement, problem solving, communication skill, and effective discipline). A combination of exploratory and confirmatory factor analysis was used in this first stage validation of the checklist. Results indicated the PCC scales obtained adequate internal consistency and interrater reliability. The confirmatory factor analysis supported 6 of the 7 expected scale domains; however, a two-factor solution was better - supported among the discipline items, labeled as effective and ineffective discipline. Test–retest reliability ranged from 0.45 to 0.80 across child behavior and parenting domains with alpha levels ranging from 0.65 to 0.88. A behavioral observation rating scale for clinicians that is reliable and feasible to implement can represent a significant improvement to practice-as-usual.     

On the representation of intentions: Do personally relevant consequences determine activation?

The intention-superiority effect describes shorter latencies for reactions to stimuli intended for future enactment, relative to stimuli associated with no enactment or canceled enactment. Previous attempts to demonstrate an intention-superiority effect for other types of tasks—for instance, observing the experimenter executing actions—have not yielded an intention-superiority effect. A reason for this could be that the typical enactment task was associated with a higher degree of personal relevance than were other laboratory-based tasks and that task importance or its consequences heighten the accessibility of intention-relevant materials. In two experiments, we demonstrate an intention-superiority effect for different types of tasks (e.g., monitoring a video clip) when task realization has personally relevant consequences in terms of a performance evaluation. In contrast, we found no intention-superiority effect when future enactment had no personally relevant consequences for participants. These findings imply that the intention-superiority effect is not restricted to actions but occurs generally for relevant plans.     

Age-related effects in interlimb practice on coding complex movement sequences

Hikosaka et al. (1999) proposed that sequential movements are acquired in independent visual-spatial and motor coordinate systems with coding initially represented in visual-spatial coordinates, and later after extended practice in motor coordinates. One aspect of sequence learning that has not been systematically studied, however, is the question of whether or not older adults show the same pattern of coding in inter-limb practice as younger learners. In the present experiment an inter-limb practice paradigm was designed to determine the role that visual-spatial (Cartesian) and motor (joint angles, activation patterns) coordinates play in the coding and learning of a complex movement sequence. Younger and older adults practiced a 16-element movement sequence with one limb on Day 1 and the contra-lateral limb on Day 2. Practice involved the same sequence with either the same visual-spatial or motor coordinates on the two days. Retention tests were conducted on Day 3. Results indicated that keeping the visual-spatial coordinates the same during acquisition resulted in superior retention only for younger adults. Results also indicated the overall slowing of sequential movement production for older adults which appears to result from these participants inability to impose a structure on the sequence. This provides strong evidence that the visual-spatial code plays a dominant role in complex movement sequences and this code is represented in an effector-independent manner for younger adults, but not for older adults.     

ERP correlates of performance monitoring in elderly

Previous studies on performance monitoring repeatedly found attenuated error-related negativities (Ne/ERN) in elderly, while findings for the correct-related negativity (Nc/CRN) are inconsistent. The present study aimed at clarifying inconsistent Nc/CRN results in elderly. Therefore, a refined design was employed to control for potential influences on the Nc/CRN, namely decision uncertainty and partial error processing. Further, we intended to study Nc/CRN variations with trial compatibility that were found in previous studies for younger but not for older adults. Results revealed increased Nc/CRN and decreased Ne/ERN amplitudes in older compared to younger adults. While the Ne/ERN was larger than the Nc/CRN in younger adults, both components were similar-sized in older adults. Further, a modulation of Nc/CRN amplitudes between compatible and incompatible trials was observed in younger adults, but was absent in older adults. Reduced differentiation of response-related negativities with response accuracy or stimulus compatibility in elderly suggests a reduced adaptation of associated processes to changing demands. Further, this might also point to different processes reflected by Nc/CRN and Ne/ERN and to reduced error-specific monitoring but increased general or strategic monitoring in elderly.     

Perception as interacting psychophysical functions. Could the configuring of features replace a specialised receptor?

This paper illustrates how perception is achieved through interactions among the psychophysical functions of judged features of an object. The theory is that the perceiver places processed features in a multidimensional space of discriminal processes. Each dimension is scaled in units of discrimination performance. The zero coordinate of each feature is its level in an internal standard (norm) established by previous experience of that category of object in context. Experiments are reported which show that one, two, or three concurrent single-featured objects matched the multiple features of another object in two ways. Either stimulation from the two objects had discrimination distances from norm that added, or the stimulation by one object was processed through a concept describing stimulation by the other object. It follows that, in this case, perception via a receptor for the multi-featured object can be replaced by a point of balance among receptors for each single feature. The object with its own receptor is the gustatory stimulant L-glutamic acid as its monosodium salt. The features that stimulate diverse gustatory receptors of their own are sodium chloride, citric acid, sucrose, and caffeine. A more complex approach to dimensional coding was developed earlier for photoreceptors in colour judgments. The present approach is modality independent, mathematically simple, and economical in experimental data.     

Reconstructing alcohol-induced memory blackouts

Many people who drink alcohol have experienced a blackout; whereby they are unable to recall events that occurred during a period of intoxication. Following these blackout episodes individuals may attempt to reconstruct what happened to them. Blackouts therefore afford an excellent opportunity to study the strategies people use to reconstruct forgotten experiences. We conducted a survey of university students to explore how people choose to reconstruct blackouts, and the likely accuracy of these reconstructions. Our findings add to the growing research literature on people's strategies for validating their past experiences, and highlight the important role of external sources in the reconstruction process. The data show that people's desire to "fill in the blanks" can lead them to rely on rather unreliable sources, and may also encourage them to adopt weaker source-monitoring criteria. Indeed, in at least some cases reconstructing blackouts appears to lead to the development of false beliefs or memories.
