The perceptual basis of the modality effect in multimedia learning

Various studies have demonstrated an advantage of auditory over visual text modality when learning with texts and pictures. To explain this modality effect, two complementary assumptions are proposed by cognitive theories of multimedia learning: first, the visuospatial load hypothesis, which explains the modality effect in terms of visuospatial working memory overload in the visual text condition; and second, the temporal contiguity assumption, according to which the modality effect occurs because solely auditory texts and pictures can be attended to simultaneously. The latter explanation applies only to simultaneous presentation, the former to both simultaneous and sequential presentation. This paper introduces a third explanation, according to which parts of the modality effect are due to early, sensory processes. This account predicts that-for texts longer than one sentence-the modality effect with sequential presentation is restricted to the information presented most recently. Two multimedia experiments tested the influence of text modality across three different conditions: simultaneous presentation of texts and pictures versus sequential presentation versus presentation of text only. Text comprehension and picture recognition served as dependent variables. An advantage for auditory texts was restricted to the most recent text information and occurred under all presentation conditions. With picture recognition, the modality effect was restricted to the simultaneous condition. These findings clearly support the idea that the modality effect can be attributed to early processes in perception and sensory memory rather than to a working memory bottleneck.     

Report on the conference on 'Men, Women, and Medicine: A New View of the Biology of Sex/Gender Differences and Aging' held in Berlin, 24–26th February 2006

The first world wide symposium on the topic of gender-specific medicine provided the latest research on differences in sex and/or gender in medicine and medical care. The presentations ranged beyond the topic of reproduction to encompass the entire human organism. This report critically reviews three issues that emerged during the Conference: gender mainstreaming, the concept of sex/gender differences and the issue of men's health. It suggests that the interdisciplinary concept of gender-specific medicine has to be mirrored by the integration of social and cultural studies into medical research and practice.     

The Image of God as Techno Sapiens

Suppose there comes a day when Homo sapiens has evolved into or been overtaken by techno sapiens. Will it then still make sense to speak of human beings as created in the image of God? What is the relevance of asking such a question today? I offer a sketch of the present state of development and discussion in artificial intelligence (AI) and artificial life (AL) and discuss some implications for the human condition. Taking into account both reality and fiction in AI and AL, I hold that, regardless of the degree of realization, issues related to technological evolution inform the cultural agenda—at least the European–American one. I comment on antireductionist arguments and on arguments from philosophy and (history of) culture. I argue in favor of a consonance between neurotechnology and the Christian gospel in terms of realizing the marks of messianic life. However, issues of justice, reason versus nature, and perfection and finitude versus imperfection and immortality call for further illumination. Even though no principal opposition seems to exist between technological evolution and possible interpretations of the concept of the image of God (imago dei), a number of significant dissimilarities need to be addressed, such as the differences between technical improvement and forgiveness or transformation and between immortality and resurrection. The role of irregularity, disturbance, and error for creative processes in nature and culture is an exciting topic in science and technology as well as in theology.     

Testing the Four Main Predictions of the Interpersonal–Psychological Theory of Suicidal Behavior in an Inpatient Sample Admitted Due to Severe Suicidality

This study aimed to evaluate four main predictions of the Interpersonal Psychological Theory of Suicide (IPTS): the importance of perceived burdensomeness (PB), thwarted belongingness (TB), hopelessness (H), and capability for suicide (CS) for (passive/active) suicide ideation, suicide intent and suicide attempts. N = 308 psychiatric inpatients admitted due to severe suicidality (53.6% female: n = 165; age: M = 36.82, SD = 14.30, range: 18–81) completed self-report measures of TB, PB, H, CS and suicide ideation as well as interviews on suicide intent and suicide attempts. TB and PB were associated with (passive/active) suicidal ideation, whereas the three-way interaction PB, TB, and H was not associated with active suicide ideation. Fearlessness about death in conjunction with active suicidal ideation was not associated with suicide intent and the interaction of PB, TB, and CS was neither predictive of recent suicide attempt status nor lifetime number of suicide attempts. Given the cross-sectional nature of the data, conclusions on causality should be handled carefully. The results challenge the theoretical validity of the IPTS and its clinical utility—at least within the methodological limitations of the current study. Yet, findings underscore the importance of PB in understanding suicidality.     

Mindfulness facets,trait emotional intelligence,emotional distress,and multiple health behaviors: A serial two‐mediator model

In the present study, we tested a serial mindfulness facets‐trait emotional intelligence (TEI)‐emotional distress‐multiple health behaviors mediation model in a sample of N = 427 German‐speaking occupational therapists. The mindfulness facets‐TEI‐emotional distress section of the mediation model revealed partial mediation for the mindfulness facets Act with awareness (Act/Aware) and Accept without judgment (Accept); inconsistent mediation was found for the Describe facet. The serial two‐mediator model included three mediational pathways that may link each of the four mindfulness facets with multiple health behaviors. Eight out of 12 indirect effects reached significance and fully mediated the links between Act/Aware and Describe to multiple health behaviors; partial mediation was found for Accept. The mindfulness facet Observe was most relevant for multiple health behaviors, but its relation was not amenable to mediation. Implications of the findings will be discussed.     

Activation of distractor names in the picture-picture interference paradigm

In four experiments, participants named target pictures that were accompanied by distractor pictures with phonologically related or unrelated names. Across experiments, the type of phonological relationship between the targets and the related distractors was varied: They were homophones (e.g., bat [animal/baseball]), or they shared word-initial segments (e.g., dog-doll) or word-final segments (e.g., ball-wall). The participants either named the objects after an extensive familiarization and practice phase or without any familiarization or practice. In all of the experiments, the mean target-naming latency was shorter in the related than in the unrelated condition, demonstrating that the phonological form of the name of the distractor picture became activated. These results are best explained within a cascaded model of lexical access--that is, under the assumption that the recognition of an object leads to the activation of its name.     

The relationship between confidence and self-concept — Towards a model of response confidence

According to Stankov [Stankov, L. (2000). Complexity, metacognition and fluid intelligence. Intelligence, 28, 121–143.] response confidence in cognitive tests reflects a trait on the boundary of personality and abilities. However, several studies failed in relating confidence scores to other known traits, including self-concept. A model of response confidence is proposed which predicts that confidence judgements do reflect self-concept, but only to the extent that they do not reflect a calibration process based on task-inherent cues. In the current study, 101 students completed various tests of cognitive abilities and skills as well as scales of the SDQ III measuring general academic and problem-solving self-concept. As expected, self-concept predicts a significant proportion of variance in the confidence factor that is over and above the influence of test scores.     

Negative emotionality,attachment quality,and behavior problems in early childhood

Negative emotionality, as well as attachment security and disorganization, are seen as major contributors to social adjustment and maladjustment in childhood. However, relatively little is known about whether infant negative emotionality and attachment quality operate together to affect developing behavior problems. The present study thus aims to contribute to this question. Participants were 64 healthy firstborn children and their primary caregivers. Negative emotionality was assessed at the infant ages of 4, 8, and 12 months using laboratory routines. At 18 months, the Strange Situation procedure was conducted to assess infant attachment security and disorganization, and at 30 months, the child's behavior problems were assessed within a structured clinical interview. Attachment security and attachment disorganization were significantly associated with subsequent behavior problems. There was no significant relation between infant negative emotionality and behavior problems. However, there were indications of a stronger association between attachment disorganization and behavior problems in infants high in negative emotionality. The results underpin the importance of attachment quality as well as negative emotionality in social adjustment. Disorganized attachment precedes poor adjustment, especially in infants high in negative emotionality.
