Whose idea was that? Source monitoring for idea ownership following elaboration

Unconscious plagiarism (UP) occurs when an individual claims a previously experienced idea as their own. Previous studies have explored the cognitive precursors of such errors by manipulating the ways that ideas are thought about between initial idea exposure and later test. While imagining other's ideas does not increase rates of UP relative to control on either a recall-own or generate-new task, improving others’ ideas substantially increases such errors in the recall-own task. This study explored the effects of elaboration on rates of UP when a source-monitoring test replaced the recall-own test. Plagiarism was again observed following idea improvement but not idea imagery even though participants engaged explicit source evaluation. Thus the probability of plagiarising another's idea appears linked to the generative nature of the idea processing performed.     

Roles of Visual Information for Control of Reaching Movements in Children

Poststroke hemiparetic individuals (n = 9) and a control group (n = 9) completed a frequency-scaled circle-drawing task in unimanual and bimanual conditions. Measures of intralimb spatial and temporal task accuracy and interlimb coordination parameters were analyzed. Significant reductions in task performance were seen in both limbs of the patients and controls with the introduction of bimanual movement. Spatial performance parameters suggested that the 2 groups focused on different hands during bimanual conditions. In the controls, interlimb coordination variables indicated predictable hand dominance effects, whereas in the patient group, dominance was influenced by the side of impairment and prior handedness of the individual. Therefore, in this particular bimanual task, performance improvements in the hemiplegic side could not be elicited. Intrinsic coupling asymmetries between the hands can be altered by unilateral motor deficits.     

Symbolic Politics and the Prediction of Attitudes Toward Federal Regulation of Reduced‐Exposure Tobacco Products1

The present study relies on symbolic politics theory to predict public attitudes toward the federal regulation of conventional tobacco products (a familiar attitude object) and reduced‐exposure tobacco products (a relatively novel attitude object). We predicted that attitudes toward most forms of regulation would be more strongly influenced by symbolic beliefs about the role of government in society than by self‐interested concerns, with the exception of taxation. We predicted that the financial consequences of taxation policies would be less ambiguous for those who are affected, resulting in a stronger relationship between self‐interest and policy attitudes. The results strongly supported our hypotheses, suggesting a process by which symbolic beliefs and self‐interested concerns influence attitude formation. Theoretical and policy implications are discussed.     

Infants’ reasoning about ambiguous motion events: The role of spatiotemporal and dispositional status information

Two experiments investigate whether 7-month-olds reason about the origin of motion events by considering two sources of causally relevant information: spatiotemporal cues and dispositional status information derived from the identification of an object as either animate (with the enduring causal property of self-initiated motion) or inanimate (requiring an external cause of motion). Infants were shown a ball, a human hand, and an animal engaged in a motion event. While dispositional status information remained constant, spatiotemporal relations varied across conditions. Based on looking time data, we conclude that infants attend flexibly to both types of information. Without spatiotemporal cues, infants rely on dispositional status information. When two objects provide dispositional cues to motion origin, but only one also provides corresponding spatiotemporal information, infants attribute the motion to the object providing both types of information. Given an ambiguous motion event with two dispositional motion originators but no additional spatiotemporal cues, infants may prefer either of the two.     

Do sex differences in a faceted model of fluid and crystallized intelligence depend on the method applied?

Recently, different methodological approaches have been discussed as an explanation for inconsistencies in studies investigating sex differences in different intelligences. The present study investigates sex differences in manifest sum scores, factor score estimates, and latent verbal, numerical, figural intelligence, as well as fluid and crystallized intelligence as measured by the German Intelligence-Structure-Test 2000-R (IST 2000-R; Liepmann, Beauducel, Brocke, & Amthauer, 2007). The not population-representative sample consisted of 977 German 11th and 12th graders enrolled in a “Gymnasium” (551 female; mean age: M = 16.70; SD = 0.65) who completed the IST 2000-R. Sex differences in fluid and crystallized intelligence were not influenced by the method applied with men performing better than women. However, extent and direction of sex differences in verbal, numerical, and figural intelligence differed by the method applied. Whereas there was a male advantage in all three factors measured as manifest sum scores, women performed better in verbal intelligence as measured by factor scores or as latent variables. Effect sizes of sex differences in numerical and figural intelligence were also greatly reduced when applying the latter two methods. Results are discussed with regard to their theoretical and practical implications.     

65 Jahre später

Research on the long-term emotional impact of World War II experiences is an important psychoanalytical issue and requires an interdisciplinary approach. In the project: “Witnesses of the ‘Operation Gomorrha (Hamburg Firestorm)’ (1943) and their families” long-term processing of and coping with war experiences of former children and adolescents are investigated by historians and psychoanalysts. A sample of 64 witnesses (34 women, 30 men, average age 75 years) and their families was recruited and investigated by semi-structured interviews. The interviews were analyzed by methods of “renarrated and interpreted history of coping” and group analysis against the background of historical, psychological and cultural approaches. A total of nine prototypical cases give insight into different biographically determined representations of the “Firestorm” and the conjunction with socio-cultural processes. Analysis of coping over the life-time has to take life experiences after the war and during the time of rebuilding into account. The research project attracts much interest among the former “war”-children.
