Training the equidistant principle of number line spacing

The characteristics of effective numerical trainings are still under scientific debate. Given the importance of number line estimation due to the strong relation between task performance and arithmetic abilities, the current study aimed at training one important number line characteristic: the equidistant spacing of adjacent numbers. Following an embodied training approach, second-graders were trained using a randomized crossover design to divide a presented line into different numbers of equal segments by walking the line with equally spaced steps. Performance was recorded, and feedback as to the correct equidistant spacing was provided using the Kinect sensor system. Training effects were compared to a control training with no involvement of task-specific whole-body movements. Results indicated more pronounced specific training effects after the embodied training. Moreover, transfer effects to number line estimation and arithmetic performance were partially observed. In particular, differential training effects for bounded versus unbounded number line estimation corroborate the assumption that not only bodily experiences but also the need for a flexible adaption of the perspective on the training material might influence training success. Hence, more pronounced training effects of the embodied training might stem from different cognitive processes involved.     

Indikation zu Psychoanalyse und analytischer Psychotherapie

Based on the diagnostic process in the initial interview, which is an intersubjective encounter, the various developmental steps for establishment of the indications for psychoanalysis are presented. Freud and his followers, who were initially oriented to the psychiatric diagnosis, were later oriented to the criteria of approachability, analysability and in particular on the aptitude for psychoanalysis. The criterion of aptitude was not only elaborated from the perspective of Ego psychology but was also relevant for all high frequency non-terminated psychoanalyses which followed the basic psychoanalytical principles of “afocality”. This has so far characterized the standard procedure of all psychoanalytic schools. Due to the experiences of psychoanalysts with early disturbed, structurally Ego-disturbed neuroses and personality disorders, the extent of lability of the mental structure and by turning to countertransference analysis, the person of the psychoanalyst become more important for the assessment of the indications. In Germany the integration of psychotherapy, which is financially supported by healthcare insurance, ultimately leads to differential indication assessments between high frequency psychoanalysis or analytical psychotherapy, modified psychoanalytical psychotherapy and less frequent psychodynamic procedures.

Dividing Attention Between Tasks: Testing Whether Explicit Payoff Functions Elicit Optimal Dual‐Task Performance

We test people's ability to optimize performance across two concurrent tasks. Participants performed a number entry task while controlling a randomly moving cursor with a joystick. Participants received explicit feedback on their performance on these tasks in the form of a single combined score. This payoff function was varied between conditions to change the value of one task relative to the other. We found that participants adapted their strategy for interleaving the two tasks, by varying how long they spent on one task before switching to the other, in order to achieve the near maximum payoff available in each condition. In a second experiment, we show that this behavior is learned quickly (within 2–3 min over several discrete trials) and remained stable for as long as the payoff function did not change. The results of this work show that people are adaptive and flexible in how they prioritize and allocate attention in a dual‐task setting. However, it also demonstrates some of the limits regarding people's ability to optimize payoff functions.     

Adoption and maltreatment of foster infants by rhesus macaque abusive mothers

In this study we investigated whether infant characteristics play a causal role in the occurrence of maternal abuse of offspring in rhesus macaques )Macaca mulatta) and whether abusive mothers differ from controls in their tendency to adopt alien infants in a cross‐fostering procedure. To this end, 13 infants born to mothers with a previous history of infant abuse were cross‐fostered shortly after birth with infants born to nonabusive mothers and subsequently observed for 12 weeks. Abusive mothers were significantly more likely to reject foster infants than control mothers were. When adoption was successful, all of the abusive mothers maltreated their foster infants whereas none of the control mothers exhibited infant abuse. These findings suggest that infant characteristics do not play an important causal role in the occurrence of infant abuse and that abusive mothers may differ from nonabusive ones in maternal motivation or reactivity to stressful procedures.     

Low ranks make the difference: How achievement goals and ranking information affect cooperation intentions

This investigation tested the joint effect of achievement goals and ranking information on information exchange intentions with a commensurate exchange partner. Results showed that individuals with performance goals were less inclined to cooperate with an exchange partner when they had low or high ranks, relative to when they had intermediate ranks. In contrast, mastery goal individuals showed weaker cooperation intentions when their ranks were higher. Moreover, participants’ reciprocity orientation was found to mediate this interaction effect of achievement goals and ranking information. These findings suggest that mastery goals are more beneficial for exchange relationships than performance goals in terms of stronger reciprocity orientation and cooperation intentions, but only among low-ranked individuals.     

Working memory and individual differences in mathematics achievement: A longitudinal study from first grade to second grade

This longitudinal study examined the relationship between working memory and individual differences in mathematics. Working memory measures, comprising the phonological loop, the visuospatial sketchpad, and the central executive, were administered at the start of first grade. Mathematics achievement was assessed 4 months later (at the middle of first grade) and 1 year later (at the start of second grade). Working memory was significantly related to mathematics achievement in both grades, showing that working memory clearly predicts later mathematics achievement. The central executive was a unique predictor of both first- and second-grade mathematics achievement. There were age-related differences with regard to the contribution of the slave systems to mathematics performance; the visuospatial sketchpad was a unique predictor of first-grade, but not second-grade, mathematics achievement, whereas the phonological loop emerged as a unique predictor of second-grade, but not first-grade, mathematics achievement.
