Films for eliciting emotional states in children

Standardized sets of films have been shown to be effective for eliciting emotional states in adults, but no comparable validated stimuli are available for children. We therefore examined the effects of three pre-selected film clips each of 3-min duration in eliciting a pleasant, neutral and unpleasant emotional state in 297 children aged between 6 and 12 years. After the films were presented on a video projector, affective ratings were obtained with the Self-Assessment-Manikin on the emotional dimensions of valence and arousal. Increasing pleasure ratings were observed from the unpleasant to the neutral to the pleasant film. Associated arousal ratings were stronger for the unpleasant and pleasant films compared to the neutral film. Overall, results showed successful elicitation of targeted emotional states only marginally influenced by age, gender or prior experience with the films. The use of these films is therefore suggested for future studies on emotions in children.     

A novel technology for investigating the dynamics of infant perseverative reaching

We designed and tested a novel technology that enables us to capture the entire stream of behavior in perseverative reaching tasks. Beyond fitting the criteria of the conventional A-not-B task, the novel technology gives us better access to the core features of perseverative reaching, such as timing, behavior history, and reinforcement. The technology allows us to quantitatively manipulate reinforcement characteristics, to accurately program onsets, delays, and stimulus durations as well as locations and salience of the targets, and to automatically record the number of reaches to each target and compute timing. We did a validation study on this new technology, investigating the influence of a number of novel factors on perseverative reaching. We replicated the A-not-B phenomenon and associated developmental changes. In addition, results demonstrated that the new technology offers insights into infants' behavior beyond the first reaching action. Moreover, data collection is fully automated, yielding precise, quantitative data. Future studies using this technology will capitalize on the salient advantages of this technology to more precisely measure goal-directed actions and understand the development of reaching skill.     

Localizing practice effects in dual-task performance

Practice effects on dual-task processing are of interest in current research because they may reveal the scope and limits of parallel task processing. Here we used onsets of the lateralized readiness potential (LRP), a time marker for the termination of response selection, to assess processing changes after five consecutive dual-task sessions with three stimulus onset asynchronies (SOAs) and priority on Task 1. Practice reduced reaction times in both tasks and the interference between tasks. As indicated by the LRP, the reduction of dual-task costs can be explained most parsimoniously by a shortening of the temporal demands of central bottleneck stages, without assuming parallel processing. However, the LRP also revealed a hitherto unreported early activation over the parietal scalp after practice in the short SOA condition, possibly indicating the isolation of stimulus-response translation from other central processing stages. In addition, further evidence was obtained from the LRP for a late motoric bottleneck, which is robust against practice.     

Stability and change in work values among male and female nurses and engineers

Gender related changes of work values were analyzed in a longitudinal questionnaire study of 173 male and 48 female engineers and 353 female and 31 male nurses at three measurement occasions covering about four and half years from the end of their vocational education. At all occasions, Social relations were rated as more important by women than by men and Altruism was given higher ratings by the nurses than by the engineers. Within both occupations women's mean Altruism ratings were higher than men's mean ratings, and in all groups except male engineers the mean ratings dropped between the three occasions. Women's ratings of Benefits and career and Influence were strengthened in both occupations, thereby eliminating an initial gender difference. The stability of work values is discussed in terms of challenges and norms in working life.     

Effects of unilateral hippocampus-amygdala-partial temporal lobe resection on auditory EEG/MEG responses: a case study

Auditory orienting and discrimination were studied with combined multi-channel EEG and MEG recordings in a patient with unilateral amygdala-hippocampus-partial temporal lobe resection of the right hemisphere. The results revealed abnormalities of habituation in alerting- and orienting-related responses, and discrimination-related responses, elicited by auditory stimulation contralateral to the resected cerebral hemisphere. These results give support to the notions about the role of the amygdala and hippocampus in alerting and orienting, respectively, and of the temporal cortex in auditory discrimination.     

Perspective effects in repeated reading: An eye movement study

The present study examined the influence of perspective instructions on online processing of expository text during repeated reading. Sixty-two participants read either a high or a low prior knowledge (HPK vs. LPK) text twice from a given perspective while their eye movements were recorded. They switched perspective before a third reading. Reading perspective affected the first-pass reading and also increased sentence wrap-up processing time in the perspective-relevant sentences. Prior knowledge facilitated the recognition of the (ir)relevance of text information and resulted in relatively earlier perspective effects in the HPK versus LPK text. Repeated reading facilitated processing, as indicated by all eye movement measures. After the perspective switch, a repetition benefit was observed for the previously relevant text information, whereas a repetition cost was found for the previously irrelevant text information. These results indicate that reading perspective and prior knowledge have a significant influence on how readers allocate visual attention during reading.     

Levels of Emotional Awareness Scale (LEAS)

Guided by the idea that alexithymia and other psychopathological phenomena are connected with decreased sensitivity to internal emotional states, Lane and Schwartz (1987) presented a cognitive-developmental theory describing different “Levels of Emotional Awareness”. In 1990, Lane et al. developed a performance measure to identify different states of sensivity to internal emotional states, the “Levels of Emotional Awareness Scale” (LEAS). Subjects are asked to describe anticipated own feelings and those of another person in 20 scenes in a short written answer. We present the results of a study using the German version of the LEAS, the 20-item-version of the Toronto Alexithymia-Scale (TAS 20) and the state-version of the State-Anxiety-Inventory (STAI) on 338 Students of medicine of the Cologne university. The study is discussed with regard to a similar study conducted in the USA (Lane et al. 1996). Theoretical background and psychometric charateristics of the LEAS are related to actual trends in research on alexithymia.     

Das Ausmaß von Müdigkeit und Erschöpfbarkeit in der über 60-jährigen Normalbevölkerung in Deutschland

In a community-based random sample of 622 elderly persons over 60 years of age, fatigue was assessed by means of the multidimensional fatigue inventory (MFI; a self-assessment measure). Higher fatigue values were found with increasing age, particularly physical feelings of fatigue, reduced activity and reduced motivation. Fatigue was associated with depression, with a low health-related quality of life and with subjective physical complaints. Distinct fatigue symptoms in the elderly should therefore be regarded as possible indicators for somatic and/or psychological burdens and should receive diagnostic and therapeutic attention. In the present paper, mean values and percentiles for different age groups over 60 years are given as norm values for the normal population over 60 years of age.
