In an experimental study the attempt was made to examine the effects of the Reciprocal Teaching method on measures of metacognition and try to identify the effective features of this method that are necessary for the learning gains to occur. Reciprocal Teaching, originally developed by Palincsar and Brown (1984), is a very successful training program which was designed to improve student's reading comprehension skills by teaching them reading strategies. In the present study the tasks and responsibilities assumed by 5thgrade elementary students (N = 55) participating in a 16-session reading strategy training were varied systematically. Not only the students who participated in the training program in one of the three experimental conditions were compared with respect to knowledge and performance measures, but there was also a comparison to their control classmates who did not participate in strategy training (N = 86). Detailed analyses of video-taped sessions provided additional information. The strategy training was most beneficial for measures of knowledge and performance more closely related to the content of the training program, namely knowledge about specific reading strategies taught in training and application of those strategies. No significant effects were observed for more distal measures (general strategy knowledge, reading comprehension). As for the features of the program, it could be shown that students of the two experimental conditions where the students were responsible for giving each other feedback on performance (with respect to both content and strategy application) and guiding the correction of the answer outperformed both the experimental condition in which the trainer was responsible for those tasks and the control group. It is concluded that it is not merely the application of strategies, but the combination of strategy application with concurrent teaching and learning of metacognitive acquisition procedures (analysis, monitoring, evaluation, and regulation) in an inter-individual way as the precedent of these processes occurring intra-individually that seems to be an efficient way of acquiring metacognitive knowledge and skills. It was also shown that strategy training does not necessarily have to include the precise kind of interaction that characterizes the Reciprocal Teaching method. Instead, the tasks of monitoring, evaluating, and regulating other children's learning processes - i.e., tasks associated with the "teacher role" - are the ones that promote the acquisition of metacognitive knowledge and skills. Generally, any strategy training program that not only provides children with plentiful opportunities for practice, but also prompts them to engage in these kinds of metacognitive processes, may help children to acquire metacognitive knowledge and skills.
Mathematical models have become an important tool for understanding the control of eye movements during reading. Main goals of the development of the SWIFT model (Engbert, Longtin, & Kliegl, 2002)were to investigate the possibility of spatially distributed processing and to implement a general mechanism for all types of eye movements we observe in reading experiments. Here, we present an advanced version of SWIFT which integrates properties of the oculomotor system and effects of word recognition to explain many of the experimental phenomena faced in reading research. We propose new procedures for the estimation of model parameters and for the test of the model’s performance. A mathematical analysis of the dynamics of the SWIFT model is presented. Finally, within this framework, we present an analysis of the transition from parallel to serial processing.

We propose two principles that facilitate integration of two relational premises in spatial reasoning. Integration is easier if the anaphor in the second premise, P2, bears the role of the relatum (relatum = given). Moreover, integration is easier if, in P2, the anaphor is mentioned before the new element (given-new). In premises with canonical word order (grammatical subjects mentioned first), these principles always conflict with one another. In topicalized statements mentioning the prepositional phrase first, the two principles work in tandem. By varying word order, we tested the two principles by measuring P2 comprehension times. Comprehension times indicated that integration was easiest when P2 obeyed both principles and most difficult when both principles were violated. Canonical premises were of intermediate difficulty. This pattern emerged regardless of whether the anaphor was a definite description or a pronoun
This paper describes the current findings concerning efficacy from randomized controlled trials of family-based interventions for children and adolescents with anxiety and depressive disorders. To date, parents have only been included in controlled trials of cognitive-behavioral interventions. Efficacy trials for anxiety disorders have only been carried out in 6- to 14-year olds, but have shown that younger children (7 to 10 years old) benefited when the family was involved. By contrast, the existing efficacy trials for depressive disorders have been limited to adolescents (13 to 18 years old), and have shown that family-based interventions are not superior to pure adolescent therapy
When participants judge the parity of visually presented digits, left-hand responses are faster for numerically small numbers, whereas right-hand responses are faster for large numbers [SNARC effect; S. Dehaene, S. Bossini, P. Giraux, The mental representation of parity and number magnitude. J. Exp. Psychol. Gen., 122, (1993) 371-396]. The present study aimed to find more direct evidence for the functional locus of this effect by recording brain waves while participants performed speeded parity judgments giving manual responses. Our results show clear and robust SNARC effects in the response-locked event-related potentials (ERPs) compared to the stimulus-locked ERPs, confirming that the SNARC effect arises during response-related rather than stimulus-related processing stages. Further analyses of lateralized readiness potentials strongly suggest that the SNARC effect begins to emerge in a response-related stage prior to response preparation and execution, more specifically, in a response selection stage.

We resolve a controversy about reading fixations before word-skipping saccades which were reported as longer or shorter than control fixations in earlier studies. Our statistics are based on resampling of matched sets of fixations before skipped and nonskipped words, drawn from a database of 121,321 single fixations contributed by 230 readers of the Potsdam sentence corpus. Matched fixations originated from single-fixation forward-reading patterns and were equated for their positions within words. Fixations before skipped words were shorter before short or high-frequency words and longer before long or low-frequency words in comparison with control fixations. Reasons for inconsistencies in past research and implications for computational models are discussed
Individual differences in women's avoidant and vigilant style in coping with the threat of rape were explored in four studies. In the first study, 97 women read a rape scenario and completed measures of cognitive vigilance and avoidance. They also provided ratings of fear of rape and anticipated coping problems in case of sexual assault. Vigilance was associated with significantly higher levels of fear of rape and anticipation of more severe coping problems. No effects were found for cognitive avoidance. Study 2 replicated these findings with a sample of 275 women. In addition, it showed that high vigilance was associated with significantly more rape-preventive behaviors. Study 3, including 172 women, was an online study on the effect of cognitive coping style on fear of rape, anticipated coping problems, and two behavioral measures of rape avoidance. High vigilance was related to higher levels of fear of rape, anticipation of more severe coping problems, and more rape-preventive behaviors. Finally, Study 4 (N = 2 10) showed that individual differences in cognitive coping style affected rape-related affect and behavior in the absence of a rape scenario, underlining the chronic salience of the threat of rape for women. Vigilance was positively related to fear of rape, rape-avoidance behavior, and anticipated coping problems. In contrast, a negative relationship was found between cognitive avoidance and fear of rape, rape-avoidance strategies, and anticipated coping problems. Across the four studies, no evidence was found for an interactive effect of cognitive avoidance and vigilance, as suggested by the construct of repression versus sensitization. The findings are discussed in the light of previous research on repression- sensitization in coping with threatening information
