Equivalent auditory distraction in children and adults.

There is an ongoing debate about whether children have more problems ignoring auditory distractors than adults. This is an important empirical question with direct implications for theories making predictions about the development of selective attention. In two experiments, the disruptive effect of to-be-ignored speech on short-term memory performance of third graders, fourth graders, fifth graders, younger adults, and older adults was examined. Three auditory conditions were compared: (a) steady state sequences in which the same distractor was repeated, (b) changing state sequences in which different distractors were presented, and (c) auditory deviant sequences in which a deviant distractor was presented in a sequence of repeated distractors. According to the attentional resource view, children should exhibit larger disruption by changing and deviant sounds due to their poorer attentional control abilities compared with adults. The duplex-mechanism account proposes that the auditory deviant effect is under attentional control, whereas the changing state effect is not, and thus predicts that children should be more susceptible to auditory deviants than adults but equally disrupted by changing state sequences. According to the renewed view of age-related distraction, there should be no age differences in cross-modal auditory distraction because some of the irrelevant auditory information can be filtered out early in the processing stream. Children and adults were equally disrupted by changing and deviant speech sounds regardless of whether task difficulty was equated between age groups or not. These results are consistent with the renewed view of age-related distraction.

The relation between awareness of personal resources and metabolic control in children and adolescents with type 1 diabetes.

INTRODUCTION: The study aims to elucidate whether awareness of personal resources, such as positive attributions and beliefs or social support, affects metabolic control in children and adolescents with type 1 diabetes. In addition, it will be determined to what extent metabolic control is influenced by concordance between children and parents regarding awareness of resources and the parents' ability to adopt their children's perspective. Also, the children's wishes particularly in relation to their illness will be investigated, as well as the kind of advice they would offer to fellow patients. METHODS: Seventy-eight children/adolescents with type 1 diabetes completed the Essen Resource Inventory for Children and Adolescents including personal, social, structural, and migration-specific resources. In addition, children/adolescents and their parents completed a systemic-oriented, diabetes-specific resource questionnaire in order to explore the parents' ability to adopt their children's perspective. RESULTS: Resources such as body awareness and open-minded attitude to the disease were associated with metabolic control. Particularly, resources associated to a migration background were found to be inversely correlated with hemoglobin A1c (HbA1c) value. Moreover, it was shown that the parents' ability to adopt their children's perspective was associated with improved metabolic control. Children advising fellow patients to accept the disease showed the best HbA1c value. DISCUSSION: This data identified specific modifiable factors related to metabolic control that can be addressed during counseling of pediatric patients. Also the parents' ability for adopting their child's perspective was identified as a relevant factor which should be considered during clinical counseling of young type 1 diabetes patients.

Development and Validation of a Questionnaire to Measure Psychosocial Work Stressors in Modern Working Environments.

OBJECTIVE: The rapid development of technology is changing working conditions of many employees. With this, appropriate measurement instruments to capture work-related psychosocial risks to create healthy working conditions are becoming more and more important. Therefore, we developed and validated a questionnaire to assess stressors in work settings which are characterized by a high degree of digitization. METHOD: The validation was based on two independent studies with data collected in four subsamples. All participants were asked about their working conditions and health-related topics using online questionnaires. RESULTS: The resulting 16-item questionnaire consists of five scales: work load, boundary permeability, participation, leader support, and usability. CONCLUSIONS: The results show that the five identified stressors showed acceptable to good values with regard to reliability (internal consistencies, test-retest reliabilities, and interrater agreement) as well as (convergent and concurrent) validity.

Time of presentation affects auditory distraction: Changing-state and deviant sounds disrupt similar working memory processes.

Four experiments tested conflicting predictions about which components of the serial-recall task are most sensitive to auditory distraction. Changing-state (Experiments 1a and 1b) and deviant distractor sounds (Experiments 2a and 2b) were presented in one of four different intervals of the serial-recall task: (1) during the first half of encoding, (2) during the second half of encoding, (3) during the first half of retention, or (4) during the second half of retention. According to the embedded-processes model, both types of distractors should interfere with the encoding and rehearsal of targets in the focus of attention. According to the duplex-mechanism account, changing-state distractors should interfere only with rehearsal, whereas deviant distractors should interfere only with encoding. Inconsistent with the latter view, changing-state and deviant distractor sounds interfered with both the encoding and the retention of the targets. Both types of auditory distraction were most pronounced during the second half of encoding when the increasing rehearsal demands had to be coordinated with the continuous updating of the rehearsal set. These findings suggest that the two types of distraction disrupt similar working memory mechanisms.

A semantic mismatch effect on serial recall: Evidence for interlexical processing of irrelevant speech.

Short-term memory (STM) for serially presented visual items is disrupted by task-irrelevant, to-be-ignored speech. Five experiments investigated the extent to which irrelevant speech is processed semantically by contrasting the following two hypotheses: (1) semantic processing of irrelevant speech is limited and does not interfere with serial STM or (2) irrelevant speech is routinely processed semantically at an interlexical level to allow for the detection of stimuli that are of potential relevance for the individual. We tested these hypotheses by comparing the disruption of serial recall by distractor sentences with semantically expected endings to that of sentences with semantically unexpected endings. Sentences with unexpected endings consistently produced more disruption than sentences with expected endings. Phonologically expected, but semantically unexpected endings had the same effect, demonstrating that a semantic and not a phonological mismatch is responsible for the increased disruption. In all five experiments, the semantic mismatch effect was not reduced after repeated exposure to sentences with unexpected endings. The results suggest that (1) semantic processing occurs at the interlexical level of irrelevant speech, which requires the integration of words into the sentence context and (2) the semantic content of a distractor interferes with the maintenance of serial information in short-term-memory if it is unexpected.

Perceived stress in human-machine interaction in modern manufacturing environments-Results of a qualitative interview study.

Rapid advances in digitization technologies are changing modern working conditions especially in industrial settings. Consequently, employees are confronted with new forms of human-machine interaction. Whether changes in working conditions in general, and the increasing relevance of human-machine interaction in particular, affect psychosocial working conditions, and employee's health is currently matter of debate, but empirical data are lacking. Therefore, we conducted semistructured interviews with 36 employees working in five different companies. The interviews were aimed at identifying potential stressors associated with the introduction and use of modern technologies in the manufacturing industry. The results show that stressors linked to human-machine interaction are technical problems, poor usability, low situation awareness, and increased requirements on employees' qualification. For example, technical problems such as breakdowns or slowdowns were described as a main stressor when employees were not qualified to handle these problems on their own, thus decelerating work flows and causing additional time pressure. Overall, the results show that problems in human-machine interaction, which have been observed in laboratory and nonindustrial settings, also apply to industrial work places with highly automated working conditions and are a potential source of stress. These factors should be considered in psychosocial risk assessment of work-related stressors.

Attentional capture by taboo words: A functional view of auditory distraction.

It is well established that task-irrelevant, to-be-ignored speech adversely affects serial short-term memory (STM) for visually presented items compared with a quiet control condition. However, there is an ongoing debate about whether the semantic content of the speech has the capacity to capture attention and to disrupt memory performance. In the present article, we tested whether taboo words are more difficult to ignore than neutral words. Taboo words or neutral words were presented as (a) steady state sequences in which the same distractor word was repeated, (b) changing state sequences in which different distractor words were presented, and (c) auditory deviant sequences in which a single distractor word deviated from a sequence of repeated words. Experiments 1 and 2 showed that taboo words disrupted performance more than neutral words. This taboo effect did not habituate and it did not differ between individuals with high and low working memory capacity. In Experiments 3 and 4, in which only a single deviant taboo word was presented, no taboo effect was obtained. These results do not support the idea that the processing of the auditory distractors' semantic content is the result of occasional attention switches to the auditory modality. Instead, the overall pattern of results is more in line with a functional view of auditory distraction, according to which the to-be-ignored modality is routinely monitored for potentially important stimuli (e.g., self-relevant or threatening information), the detection of which draws processing resources away from the primary task.

Semantic priming by irrelevant speech.

To-be-ignored, task-irrelevant speech disrupts serial recall performance relative to a quiet control condition. In most studies, the content of the auditory distractors had no effect on their disruptive potential, one's own name being one of the few exceptions. There are two possible explanations of this pattern: (1) Semantic features of the irrelevant speech are usually not processed, except for highly relevant auditory distractors, or (2) semantic processing of the irrelevant speech always occurs, but usually does not affect serial recall performance. To test these explanations, we presented to-be-ignored auditory distractor words drawn from different categories while participants memorized visual targets for serial recall. Afterwards, participants were invited to what they believed to be an unrelated norming study, in which they were required to spontaneously produce words from the categories from which the auditory distractor words were drawn. Previously ignored words were produced with a higher probability than words from a parallel, nonpresented set, demonstrating that features of to-be-ignored, task-irrelevant speech that do not interfere with immediate serial recall performance are nevertheless processed semantically and may have substantial effects on subsequent behavior.
