Auditory warnings, signal-referent relations, and natural indicators: re-thinking theory and application

In auditory warning design the idea of the strength of the association between sound and referent has been pivotal. Research has proceeded via constructing classification systems of signal-referent associations and then testing predictions about ease of learning of different levels of signal-referent relation strength across and within different types of auditory signal (viz., speech, abstract sounds, and auditory icons). However, progress is hampered by terminological confusions and by neglect of the cognitive contribution (viz., learning) of the person or user. Drawing upon semiotics and cognitive psychology, the authors highlight the indexical (as opposed to iconic) nature of so-called auditory icons, and the authors identify the cogniser as an indispensable element in the tripartite nature of signification. Classifications that neglect this third element, defining signal-referent relation strength only dyadically, yield results confounded by learning; classifications that correctly include the triadic relation yield research predictions that are redundant. These limitations of the standard method of constructing and testing classification systems suggest that auditory warning design must take the cognitive contribution of the user into account at an earlier stage in the design process.     

Effects of mental imagery styles on shoulder and hip rotations during preparation of pirouettes

To analyze individual behavior in spatial navigation especially for pirouette preparations (complete whole-body rotations), the authors studied horizontal shoulder-hip interactions under 2 constraints: postural (right and left supporting legs [SL]) and spatial (clockwise [CW] and counterclockwise [CCW]). They performed kinematic analysis at the start and end of the shoulder-hip horizontal rotations (run-up) with regard to imagery of motor actions. On the basis of the Vividness of Movement Imagery Questionnaire, they classified 8 female expert ballet dancers and 7 untrained female participants according to their movement imagery style (kinesthetic and visual). At the run-up's end, the shoulders initiated the turn independently of SL but differently depending on training: CW for dancers and CCW for untrained participants (their commonly used direction). Kinesthetic and mixed imagery styles prevailed in dancers, whereas simply a mixed style appeared among untrained participants. Thus, dance training enhances the imagery of kinesthetic sensation and influences the choice of spatial direction, facilitating the body-space interaction.     

Sensorimotor synchronization with adaptively timed sequences

Most studies of human sensorimotor synchronization require participants to coordinate actions with computer-controlled event sequences that are unresponsive to their behavior. In the present research, the computer was programmed to carry out phase and/or period correction in response to asynchronies between taps and tones, and thereby to modulate adaptively the timing of the auditory sequence that human participants were synchronizing with, as a human partner might do. In five experiments the computer's error correction parameters were varied over a wide range, including "uncooperative" settings that a human synchronization partner could not (or would not normally) adopt. Musically trained participants were able to maintain synchrony in all these situations, but their behavior varied systematically as a function of the computer's parameter settings. Computer simulations were conducted to infer the human participants' error correction parameters from statistical properties of their behavior (means, standard deviations, auto- and cross-correlations). The results suggest that participants maintained a fixed gain of phase correction as long as the computer was cooperative, but changed their error correction strategies adaptively when faced with an uncooperative computer.     

Grandmaternal and maternal ethnotheories about early child care.

Parenting ethnotheories represent an organized set of ideas about parents, children, and development that are shared by members of cultural groups. Because these ideas and beliefs reflect cultural models and serve as representational frameworks for parenting strategies, they need to change with historical time. To analyze these changes, the authors interviewed mothers and grandmothers of 3-month-old infants in 4 different cultural environments--urban German middle-class families (41 mothers, 22 grandmothers), urban Indian middle-class families (36 mothers, 12 grandmothers), rural Cameroonian Nso families (29 mothers, 20 grandmothers), and urban Cameroonian Nso families (28 mothers, 12 grandmothers)--in regard to their ideas about infant care. The interviews were analyzed according to content and discourse style. The results reveal that there is not only transmission of parental beliefs from one generation to the next but also variation in adaptation to changing environments. Although the global trend toward more independent cultural models of parenting is confirmed, the magnitude of change varies across the different cultural environments.     

Culture and Biology: The Foundation of Pathways of Development

This paper develops the argument that the relationship of biology and culture is systematic: evolved predispositions and learning devices allow individuals to acquire contextually relevant information to become competent in particular environments. It is proposed to synthesize evolutionary theory with cultural and indigenous approaches defining cultural contexts on the basis of shared practices and shared beliefs. Human development can be understood as a series of evolved developmental tasks that need to be solved locally to define adaptive life histories. Early parenting strategies are defined for two prototypical sociocultural contexts: rural farmers in traditional non‐Western villages and urban Western middle‐class families. Parenting strategies are supposed to lay the foundation during the brain imprint period of infancy for different developmental pathways of self‐development.     

Welfare and the Achievement of Goals

I defend the view that an individual's welfareis in one respect enhanced by the achievementof her goals, even when her goals are crazy,self-destructive, irrational or immoral. This``Unrestricted View' departs from familiartheories which take welfare to involve only theachievement of rational aims, or of goals whoseobjects are genuinely valuable, or of goalsthat are not grounded in bad reasons. I beginwith a series of examples, intended to showthat some of our intuitive judgments aboutwelfare incorporate distinctions that only theUnrestricted View can support. Then, I show howthe view can be incorporated into a broadertheory of welfare in ways that do not produceimplausible consequences. This in hand, Ifinish by providing a more philosophicalstatement of the Unrestricted View and the casein its favor, and respond to some objections.     

Psychosoziale Interventionen bei Patientinnen mit Brustkrebs

Breast cancer patients are subject not only to physical strain but also to substantial psychological and social stress as well as major threats and challenges.The paper presented gives an overview of the research status on psychosocial interventions to support patients in their coping endeavours.Psychosocial basic care of women with breast cancer is performed by the physicians treating oncologically and includes information fitting patients' information needs,and responding to their emotional stress.Evaluated training and educational programs are available for physicians to enhance their psychosocial competence.Psychosocial basic care is completed by psychoeducational interventions.In 20–30% of women with breast cancer, there is a need for a special psychotherapeutic treatment.Especially, supportive and cognitive-behavioral therapies in an individual or a group setting contribute to a reduction of anxiety and depression. Even anticipated side-effects of somatic treatments can be diminished by psychotherapy. Research in the field supports that there is a need for broad integration of psychosocial interventions into disease management programs for women suffering from breast cancer.     

Physiological aspects of flow experiences: Skills-demand-compatibility effects on heart rate variability and salivary cortisol

This research addresses flow theory according to which the compatibility of skills and task demands involved in an activity elicits flow experiences that render the activity intrinsically rewarding. Departing from correlational research, we applied experimental paradigms designed to test the impact of a skills-demands-compatibility on the emergence of flow in computerized tasks. On the one hand, the results from self-reports support the balance hypothesis and indicate that skills-demands-compatibility results in a pleasurable flow experience. On the other hand, the results also indicate that skills-demands-compatibility resulted in (a) reduced heart rate variability indicating enhanced mental workload, and (b) stress as indicated by relatively high levels of salivary cortisol. These results indicate that flow experiences combine subjectively positive elements with physiological elements reflecting strainful tension and mental load.
