Do current connectionist learning models account for reading development in different languages?

Learning to read a relatively irregular orthography, such as English, is harder and takes longer than learning to read a relatively regular orthography, such as German. At the end of grade 1, the difference in reading performance on a simple set of words and nonwords is quite dramatic. Whereas children using regular orthographies are already close to ceiling, English children read only about 40% of the words and nonwords correctly. It takes almost 4 years for English children to come close to the reading level of their German peers. In the present study, we investigated to what extent recent connectionist learning models are capable of simulating this cross-language learning rate effect as measured by nonword decoding accuracy. We implemented German and English versions of two major connectionist reading models, Plaut et al.'s (Plaut, D. C., McClelland, J. L., Seidenberg, M. S., & Patterson, K. (1996). Understanding normal and impaired word reading: computational principles in quasi-regular domains. Psychological Review, 103, 56-115) parallel distributed model and Zorzi et al.'s (Zorzi, M., Houghton, G., & Butterworth, B. (1998a). Two routes or one in reading aloud? A connectionist dual-process model. Journal of Experimental Psychology: Human Perception and Performance, 24, 1131-1161); two-layer associative network. While both models predicted an overall advantage for the more regular orthography (i.e. German over English), they failed to predict that the difference between children learning to read regular versus irregular orthographies is larger earlier on. Further investigations showed that the two-layer network could be brought to simulate the cross-language learning rate effect when cross-language differences in teaching methods (phonics versus whole-word approach) were taken into account. The present work thus shows that in order to adequately capture the pattern of reading acquisition displayed by children, current connectionist models must not only be sensitive to the statistical structure of spelling-to-sound relations but also to the way reading is taught in different countries.     

Patient Autonomy and Quality of Care in Telehealthcare

Telemedicine is a complex field including various applications and target groups. Especially telehealthcare is seen by many as a means to revolutionize medicine. It gives patients the opportunity to take charge of their own health by using self-tracking devices and allows health professionals to treat patients from a distance. To some, this means an empowerment of patient autonomy as well as an improvement in the quality of care. Others state the dangers of depersonalization of medicine and the pathologization of daily life. This paper examines the ethical implications of telehealthcare, focusing on patient autonomy and quality of care by analyzing metareviews, randomized controlled trials and narrative ethical analyses on the topic. As a result, we conclude that the technically enhanced encounter between patients and health professionals may mean an empowerment of patient autonomy when it goes along with a personal relationship based on trust, assistance and support. When it comes to the quality of care, telehealthcare may lead to an improvement as long it is adopted to the patient’s individual needs.     

Why compatibilist intuitions are not mistaken: A reply to Feltz and Millan

In the past decade, a number of empirical researchers have suggested that laypeople have compatibilist intuitions. In a recent paper, Feltz and Millan (2015 Feltz, A., &; Millan, M. (2015). An error theory for compatibilist intuitions. Philosophical Psychology, 28(4), 529–555.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) have challenged this conclusion by claiming that most laypeople are only compatibilists in appearance and are in fact willing to attribute free will to people no matter what. As evidence for this claim, they have shown that an important proportion of laypeople still attribute free will to agents in fatalistic universes. In this paper, we first argue that Feltz and Millan’s error-theory rests on a conceptual confusion: it is perfectly acceptable for a certain brand of compatibilist to judge free will and fatalism to be compatible, as long as fatalism does not prevent agents from being the source of their actions. We then present the results of two studies showing that laypeople’s intuitions are best understood as following a certain brand of source compatibilism rather than a “free-will-no-matter-what” strategy.     

The costs and benefits of cross-task priming

Two lines of research on cross-task priming yield opposite results. Research on repetition priming observed positive priming, whereas research on the role of priming in task-switching observed negative effects. We combined the two types of design. In the transfer phase of our paradigm, subjects performed task B either as a pure block (BBB) or as a switch block (ABAB). We presented items which were either unprimed or primed by prior presentation during a preceding priming phase performed on task A. Amongst others, the priming effect is determined by two factors: First, the more operation time the system needs during the probe event, the higher the likelihood to obtain priming. Protracting operation time by reducing stimulus quality favors positive priming, whereas providing more operation time by making subjects switch between tasks favors negative priming. Second, the strength of the memory trace of the prime event determines whether that trace can possibly yield negative priming, in that only strong traces can be retrieved together with the associated task/response.

Is Self‐Determined Functioning a Universal Prerequisite for Motive–Goal Congruence? Examining the Domain of Achievement in Three Cultures

ABSTRACT Research has shown that capacity for accessing implicit motives promotes congruence between the implicit and the explicit motivational system: Individuals able to test a conscious goal for its fit with their implicit motivation commit themselves more fully to self‐congruent goals. However, it has not yet been shown whether this is a universal phenomenon or limited to Euro‐American cultures in which individual needs are less strictly constrained by the social environment than in other cultural contexts. Thus, the present study examined whether self‐determination interacts with the implicit achievement motive to predict how much importance individuals from Cameroon, Germany, and Hong Kong ascribe to achievement goals. Moreover, the importance ascribed to goals should indirectly predict life satisfaction via success in goal realization. Results showed that the associations described above are valid in all three cultural groups and are discussed in terms of their implications for the universal processes characterizing motivation.     

The rational side of egocentrism in social comparisons

Prior work has found that when people compare themselves with others they egocentrically focus on their own strengths and achievements more than on the (equally relevant) strengths and achievements of the comparison group. As a consequence, people tend to overestimate their comparative standing when absolute standing is high and underestimate their comparative standing when absolute standing is low. The present research investigated a rational discounting explanation of this bias—namely, that people weight the target of the comparison (the self) more than the referent of the comparison (others) because they typically have more knowledge about the former than the latter. In three studies, we found that the tendency to focus on the target in social comparisons—and the over and underestimation of relative standing that tendency engenders—was reduced (but not eliminated) as people’s knowledge about the comparison group increased. These results suggest that there may be a rational side to egocentrism in social comparisons.     

An incremental boundary study on parafoveal preprocessing in children reading aloud: Parafoveal masks overestimate the preview benefit

Parafoveal preprocessing is an important factor for efficient reading and, in eye-movement studies, is typically investigated by means of parafoveal masking: Valid previews are compared to instances in which masks prevent preprocessing. A long-held assumption was that parafoveal preprocessing, as assessed by this technique, only reflects facilitation (i.e., a preview benefit). Recent studies, however, suggested that the benefit estimate is inflated due to interference of the parafoveal masks, i.e., the masks inflict processing costs. With children from Grades 4 and 6, we administered the novel incremental priming technique. The technique manipulates the salience of the previews by systematically varying its perceptibility (i.e., by visually degrading the previews). This technique does not require a baseline condition, but makes it possible to determine whether a preview induces facilitation or interference. Our salience manipulation of valid previews revealed a preview benefit in the children of both Grades. For two commonly used parafoveal masks, we observed interference corroborating the notion that masks are not a proper baseline. With the novel incremental boundary technique, in contrast, one can achieve an accurate estimate of the preview benefit.
