Handwriting or Typewriting? The Influence of Pen- or Keyboard-Based Writing Training on Reading and Writing Performance in Preschool Children

Digital writing devices associated with the use of computers, tablet PCs, or mobile phones are increasingly replacing writing by hand. It is, however, controversially discussed how writing modes influence reading and writing performance in children at the start of literacy. On the one hand, the easiness of typing on digital devices may accelerate reading and writing in young children, who have less developed sensory-motor skills. On the other hand, the meaningful coupling between action and perception during handwriting, which establishes sensory-motor memory traces, could facilitate written language acquisition. In order to decide between these theoretical alternatives, for the present study, we developed an intense training program for preschool children attending the German kindergarten with 16 training sessions. Using closely matched letter learning games, eight letters of the German alphabet were trained either by handwriting with a pen on a sheet of paper or by typing on a computer keyboard. Letter recognition, naming, and writing performance as well as word reading and writing performance were assessed. Results did not indicate a superiority of typing training over handwriting training in any of these tasks. In contrast, handwriting training was superior to typing training in word writing, and, as a tendency, in word reading. The results of our study, therefore, support theories of action-perception coupling assuming a facilitatory influence of sensory-motor representations established during handwriting on reading and writing.     

Effects of wakeful resting versus social media usage after learning on the retention of new memories

Communication and information sharing via social media platforms is a common and popular activity. The majority of existing studies indicate that social media usage has detrimental effects on learning and memory. However, it is an open question as to whether social media usage affects memory even after learning. To test this, healthy young adults learned and immediately recalled a vocabulary list. Subsequent to recall, participants either wakefully rested for 8 min or used social media for 8 min. A delayed recall test took place after the wakeful resting condition and the social media condition and again after 1 day. Our results showed that social media usage, compared with wakeful resting, had detrimental effects on memory performance over both retention intervals. We assume that social media usage interfered with memory consolidation of learned vocabularies and suggest that learners opt for wakeful resting over social media usage as a learning-break activity.     

Visual Attention in Real-World Conversation: Gaze Patterns Are Modulated by Communication and Group Size

Gaze behavior both initiates and maintains conversations, playing a crucial role in real-world collaboration. Hitherto, most findings on social attention stem from research using pictures of faces in the laboratory, however, attention operates differently in the real world. Thus, we know little of how gaze behavior operates in naturalistic interactions. To bridge this gap, we applied mobile eye-tracking to investigate the gaze patterns present in naturalistic conversations. Specifically, we examined gaze behavior of participants in a group of two or five, either sitting together in silence, or engaging in a conversation, in which they took turns either listening or speaking to each other. Results show that participants looked more frequently towards others when the group was communicating compared to when remaining silent, and that they looked at others more frequently when listening compared to when speaking. Furthermore, being part of a dyad led to more social attention being afforded during conversation compared to the group situation, regardless of whether subjects were listening or speaking. Meanwhile, when sitting in silence subjects showed less social gazing in a dyad than in a group of five. Our results provide qualitative and quantitative insights into the patterns of visual attention during dynamic naturalistic conversations.     

Investigating word class effects in first and second languages

According to Zyzik in 2009, only a few recent studies have investigated similarities in use of words in comprehension of first languages (L1) and second languages (L2). Furtner, Rauthmann, and Sachse showed a rank order of word classes by frequency of eye-gaze regression when reading other difficult words: nouns, adjectives, closed-class words, verbs. The hypothesis was that a L1-L2 word-class similarity effect between German (L1) and English (L2) would occur, and this was tested with jumbled word reading of English text (wherein letters within words Shave been jumbled) and eye-tracking by 141 participants. Analyses of regressive fixations from one word class to others showed that nouns were regressed most often and there was a rank order of importance among the word classes apparently used to enhance comprehension of other difficult words (nouns, adjectives, verbs, dosed-class words). Thus, previous findings for L1 were largely replicated. Findings are discussed regarding language acquisition.     

Eye movements during mental rotation of nonmirrored and mirrored three-dimensional abstract objects

Eye movements were recorded while participants (N = 56) rotated mirrored and nonmirrored abstract, three-dimensional object pairs into different orientations to assess whether there were oculomotoric differences in fixation switches between mirrored and nonmirrored objects and how an object's plane and depth angle affected visual processing. Compared to other studies, especially depth rotation tasks were responsible for a difference in the sum of fixation switches. This difference seemed to be caused by an increase in incongruent fixation switches, while congruent ones remained stable. Theoretical and practical implications of findings are discussed.     

The programming of structural properties of movement sequences

Summary The present paper investigates the role of abstract structural properties in the programming and execution of movement sequences. Three experiments, using converging methods, demonstrate that the motor system represents the abstract structural properties of movement sequences. The first two experiments show that hierarchical structures over a sequence of tapping movements can be used to prepare the motor program, even if the specific elements of the sequence are still unknown. Experiment 2 also shows that the preliminary programming of structural properties of a movement sequence takes more time than the programming of specific elements ( start elements). Experiment 3 suggests that abstract structural properties can be generalized from a special sequence and that they are transferable to other sequences. Abstract structural properties are assumed to be an important component of generalized motor programs.     

What About a Reductionist Approach? Comments on Terry Horgan

In his work, Horgan argues for the compatibilism of agency, mental state-causation, and physical causal-closure. We generally assume a causally closed physical world that seems to exclude agency in the sense of mental state-causation in addition to physical causation. However, Horgan argues for an account of agency that satisfies the experience of our own as acting persons and that is compatible with physical causal-closure. Mental properties are causal properties but not identical with physical properties because there are different ontological levels. In this commentary, I shall reconsider the essential issues of this compatibilism (1), focus on a problem for Horgan’s conception of agent causation that arises from the causal argument for ontological reductionism (2), and propose to embed Horgan’s conception of agency within a reductionist approach in order to vindicate the indispensable character of agency (3).

External thought—does sketching assist problem analysis?

An experimental study (n = 60 students) tests the advantages of being allowed to sketch a representation of a mechanical system (involving components such as weights, ropes and pulleys) when one is to be subsequently asked questions about this system. In comparison to a control group who were not allowed to sketch the system, the main advantages of sketching were found to be a reduction in the perceived difficulty of the problems and an increase in the likelihood of correctly inferring relations between the components. These advantages came at no extra cost in terms of additional time being needed to analyse the situation or solve the problems. However, sketching conferred no advantage in terms of the correct recall of system components. Copyright © 2004 John Wiley & Sons, Ltd.
