The leaflet was identified in a previous study as addressing research-based cognitive antecedents of condom use. A pre-post-test experimental study including three conditions was conducted: (a) presentation of the leaflet; (b) presentation of the leaflet plus incentive for systematic processing; (c) no-leaflet control. The leaflet was evaluated in terms of its capacity to change eight cognitive correlates of condom use identified in a recent meta-analysis. The sample consisted of 230 tenth-grade students. Following baseline assessments, leaflet-induced change was measured immediately following the intervention and at a follow up 4 weeks post-intervention. The target leaflet alone did not result in significant changes in the cognitive antecedents of condom use compared with the control condition. However, in combination with an incentive for systematic processing, the target leaflet had a greater impact on cognitive antecedents than the no-leaflet control condition. The findings are discussed with regard to the development and evaluation of research-based health-promotion materials Y1 - 2006 SN - 1359-107X ER - TY - JOUR A1 - Richter, Eike M. A1 - Engbert, Ralf A1 - Kliegl, Reinhold T1 - Current advances in SWIFT N2 - Models of eye movement control are very useful for gaining insights into the intricate connections of different cognitive and oculomotor subsystems involved in reading. The SWIFT model (Engbert, Longtin, & Kliegl (2002). Vision Research, 42, 621 - 636) proposed a unified mechanism to account for all types of eye movement patterns that might be observed in reading behavior. The model is based on the notion of spatially distributed, or parallel, processing of words in a sentence. We present a refined version of SWIFT introducing a letter-based approach that proposes a processing gradient in the shape of a smooth function. We show that SWIFT extents its capabilities by accounting for distributions of landing positions.

A1 - Becker, Katja T1 - Association between ADHD and smoking in adolescence : shared genetic, environmental and psychopathological factors N2 - The present study aimed to examine the extent to which the co-occurrence of ADHD and smoking in adolescents could be attributed to common genetic, environmental and psychopathological factors. Data are from an ongoing prospective study of the outcome of early risk factors. At age 15 years, 305 adolescents completed self-report questionnaires measuring tobacco consumption and deviant peer affiliations. Lifetime psychiatric diagnoses were obtained using standardized interviews. DNA was genotyped for the dopamine D4 receptor (DRD4) gene exon III polymorphism. Adolescents with a lifetime diagnosis of ADHD displayed significantly higher smoking activity than non-ADHD controls. A major component of this association could be accounted for by deviant peer affiliations and the comorbidity with oppositional-defiant and conduct disorder, while a minor part was attributable to DRD4 in males but not in females. These findings suggest that the association of ADHD with smoking relies on risk factors shared by the two behaviors.

O. Miller, 1986) and temporal order judgments (TOJs) share many important similarities and address related questions concerning the time course of sensory processing. The author of this article proposes and tests a new aggregate diffusion-based model to quantitatively explain both the RSE and TOJs and the relationship between them. Parametric data (13 stimulus onset asynchronies) from an experiment with pairs of visual stimuli (626-nm LEDs) confirm that, relative to central signals (3 degrees), peripheral signals (35 degrees) yield slower reaction times, more strongly modulated RSE time-course functions, and flatter TOJ psychometric functions. All of these qualitative features are well captured, even in quantitative detail, by the aggregate diffusion model Y1 - 2006 ER - TY - JOUR A1 - Kliegl, Reinhold A1 - Bates, Douglas T1 - International collaboration in psychology is on the rise N2 - There has been a substantial increase in the percentage for publications with co-authors located in departments from different countries in 12 major journals of psychology. The results are evidence for a remarkable internationalization of psychological research, starting in the mid 1970s and increasing in rate at the beginning of the 1990s. This growth occurs against a constant number of articles with authors from the same country; it is not due to a concomitant increase in the number of co-authors per article. Thus, international collaboration in psychology is obviously on the rise.

Since their first description more than 40 years ago, the role of microsaccades in vision has been controversial. In this issue, Martinez-Conde and colleagues present a solution to the long-standing research problem connecting this basic oculomotor function to visual perception, by showing that microsaccades may control peripheral vision during visual fixation by inducing flips in bistable peripheral percepts in head-unrestrained viewing. Their study provides new insight into the functional connectivity between oculomotor function and visual perception Y1 - 2006 UR - http://www.neuron.org/ U6 - https://doi.org/10.1016/j.neuron.2006.01.005 SN - 0896-6273 ER - TY - JOUR A1 - Kliegl, Reinhold A1 - Nuthmann, Antje A1 - Engbert, Ralf T1 - Tracking the mind during reading : the influence of past, present, and future words on fixation durations N2 - Reading requires the orchestration of visual, attentional, language-related, and oculomotor processing constraints. This study replicates previous effects of frequency, predictability, and length of fixated words on fixation durations in natural reading and demonstrates new effects of these variables related to previous and next words. Results are based on fixation durations recorded from 222 persons, each reading 144 sentences. Such evidence for distributed processing of words across fixation durations challenges psycholinguistic immediacy-of-processing and eye- mind assumptions. Most of the time the mind processes several words in parallel at different perceptual and cognitive levels. Eye movements can help to unravel these processes Y1 - 2006 UR - http://psycnet.apa.org/index.cfm?fa=browsePA.volumes&jcode=xge&vol=135&issue=1 U6 - https://doi.org/10.1037/0096-3445.135.1.12 SN - 0096-3445 ER - TY - JOUR A1 - Oberauer, Klaus A1 - Göthe, Katrin T1 - Dual-task effects in working memory : interference between two processing tasks, between two memory demands, and between storage and processing N2 - Two experiments with a working-memory updating task investigated dual-task interference between short-term storage of numerical and spatial material, between execution of a numerical and a spatial updating operation, and between storage and processing. Participants memorised a set of digits and a set of spatial positions, updated elements of both sets by a sequence of operations, and then recalled the final values. In Experiment 1, a single element in each memory set had to be updated several times. There was little interference between storage of the two sets, and between storage and processing, but parallel execution of the two operations was not possible. In Experiment 2, all elements in both memory sets were updated in random order. There was substantial interference between memory for the numerical and the spatial sets, and between storage and processing. Parallel execution of two operations was again not possible. Moreover, trying to do two operations simultaneously resulted in impaired memory of final results. The results support the distinction between the activated part of long-term memory that can hold elements currently not needed for processing, and a more central, capacity-limited part of working memory that provides access to its contents for processing Y1 - 2006 UR - http://www.informaworld.com/openurl?genre=journal&issn=0954-1446 U6 - https://doi.org/10.1080/09541440500423038 ER - TY - JOUR A1 - Vollmeyer, Regina A1 - Rheinberg, Falko T1 - Motivational Effects on self-Regulated learning with different Tasks JF - Educational psychology review N2 - In our cognitive motivational process model (Vollmeyer & Rheinberg, Zeitschrift für Pädagogische Psychologie, 12:11–23, 1998) we assume that initial motivation affects performance via motivation during learning and learning strategies. These variables are also central for self-regulation theories (e.g., M. Boekaerts, European Psychologist, 1:100–122, 1996). In this article we discuss methods with which the model can be tested. Initial motivation with its four factors challenge, probability of success, interest, and anxiety was measured with the Questionnaire on Current Motivation (QCM; Rheinberg, Vollmeyer, & Burns, Diagnostica, 47:57–66, 2001). As an indicator for the functional state we assessed flow with the FKS (Rheinberg, Vollmeyer, & Engeser, Diagnostik von Motivation und Selbstkonzept [Diagnosis of Motivation and Self-Concept], Hogrefe, Göttingen, Germany, 261–279, 2003). We also used different tasks, including a linear system, a hypermedia program, and university-level classes. In general, our methods are valid and with them we found support for our model.
