Learning from text benefits from enactment

Classical studies on enactment have highlighted the beneficial effects of gestures performed in the encoding phase on memory for words and sentences, for both adults and children. In the present investigation, we focused on the role of enactment for learning from scientific texts among primary-school children. We assumed that enactment would favor the construction of a mental model of the text, and we verified the derived predictions that gestures at the time of encoding would result in greater numbers of correct recollections and discourse-based inferences at recall, as compared to no gestures (Exp. 1), and in a bias to confound paraphrases of the original text with the verbatim text in a recognition test (Exp. 2). The predictions were confirmed; hence, we argue in favor of a theoretical framework that accounts for the beneficial effects of enactment on memory for texts.     

Meaning from syntax: Evidence from 2-year-olds

When toddlers view an event while hearing a novel verb, the verb’s syntactic context has been shown to help them identify its meaning. The current work takes this finding one step further to reveal that even in the absence of an accompanying event, syntactic information supports toddlers’ identification of verb meaning. Two-year-olds were first introduced to dialogues incorporating novel verbs either in transitive or intransitive sentences, but in the absence of any relevant referent scenes (see Yuan & Fisher, 2009). Next, toddlers viewed two candidate scenes: (a) two participants performing synchronous actions, (b) two participants performing a causative action. When asked to “find mooping”, toddlers who had heard transitive sentences chose the causative scene; those who had heard intransitive sentences did not. These results demonstrate that 2-year-olds infer important components of meaning from syntactic structure alone, using it to direct their subsequent search for a referent in a visual scene.     

分清科学与伪科学、宗教与邪教

20世纪80、90年代,我国伪科学和邪教大量出现,给我国社会和人民带来巨大危害,它们都宣称自己是科学,是宗教;不承认自己是伪科学,是邪教;甚至参与批判别的伪科学、邪教,以显示自己是科学,是宗教。这样就搅浑了水,混淆了视听,使人真伪莫辨,便于它们浑水摸鱼,在浑水中生存和发展。它们也正是在这种情况下发展起来。     

Rising from the ashes: Recovery from physical trauma

A counsellor describes her trauma accompanying an accidental physical injury, and the course of psychological recovery during the following 6 weeks. The style of self-analysis which was used during this period reflects the transpersonal approach, using imagery and the intuitive function to increase self-awareness, with moments of therapeutic insight ('release' experiences) at the landmarks en route to a healthy state of re-integration. The implications of the whole experience are discussed in terms both of post-traumatic stress and of personal growth.     

Forensic-psychologic-psychiatric assessment from the viewpoint of perpetrators--data from a survey

In this contribution, various aspects of the expert/culprit-relationship and of the communication behavior styles between the included persons within the scope of forensic-psychological-psychiatric expertise, are discussed. A survey is given on results gained with a questionnaire study (n = 93 culprits; Department of Forensic Psychiatry, Charité Berlin) of the most important expectations, of the social-relevant attitudes towards the assessment and physicians before the forensic investigation as well as of the experiences of own feelings, stress and of the culprit's reflections on the physician/proband relationship after the assessment. A good partnership relation between experts and culprits presupposes that the expert not only possesses a high profession but also the necessary interpersonal-social competence.     

Discriminating constant from variable angular velocities in structure from motion

We investigated accuracy in discriminating between constant and variable angular velocities for orthographic projections of three-dimensional rotating objects. The reported judgments of “constant” or “variable” angular velocity were only slightly influenced by the projected angular velocities, but they were greatly affected by the variations of the deformation, a first-order component of the optic flow. When viewing either a rotating ellipsoidal volume or a planar surface that accelerated and decelerated over the course of rotation, observers’ tendencies to report a variable angular velocity were increased when the temporal phase of the acceleration pattern increased the range of variation of the median deformation; the tendencies were decreased when the same acceleration pattern was used to decrease the range of variation of the median deformation. These results provide evidence contrary to the hypothesis that the visual system performs a mathematically correct analysis of the optic flow.     

Salience from multiple feature contrast: Evidence from saccade trajectories

We used eye tracking to quantify the extent to which combinations of salient contrasts (orientation, luminance, and movement) influence a central salience map that guides eye movements. We found that luminance combined additively with orientation and movement, suggesting that the salience system processes luminance somewhat independently of the two other features. On the other hand, orientation and movement together influenced salience underadditively, suggesting that these two features are processed nonindependently. This pattern of results suggests that the visual system does not sum sources of salience linearly, but treats some sources of salience as redundant.

     

Pleasure and displeasure from the body: Perspectives from exercise

We investigated some types of triggers of embarrassment and their personality correlates. A total of 161 undergraduates indicated how embarrassed they would be in a variety of situations classified a priori into three types. The types were based on the kind of trigger they embodied and were derived in part from current theories of embarrassment. Several analytic techniques, including factor analysis, suggested that there are at least three sorts of situations people find embarrassing: committing a faux pas, being the centre of attention, and threatening another's social identity. We created a subscale for each subtype of trigger. Embarrassibility on each subscale was correlated with embarrassibility on the others, but the reliabilities of the subscales substantially exceeded their intercorrelations. Some personality variables, for example, Neuroticism (Eysenck & Eysenck, 1975) correlated with all subscales, whereas other personality variables correlated differentially, for example, Revised Self-Monitoring (Lennox & Wolf, 1984), Interaction Anxiousness (Leary, 1983), and Rejection Sensitivity (Downey & Feldman, 1996). We believe, contrary to previous suggestions (Edelmann & McCusker, 1986), that there are subtypes of triggers of embarrassment and they they roughly correspond to the different causes of embarrassment as proposed by various theorists. We discuss the implications of our results for theories of embarrassment.

Recovery from hemialexia

Hemialexia is believed to be caused by the lesion of the splenium of the corpus callosum. However, no previous reports conclusively demonstrated that the hemialexic had the splenial lesion. A right-handed male with hemialexia who was presumed to have the splenium sectioned for a partial removal of a pineal tumor was examined with magnetic resonance imaging. The sagittal and coronal imagings clearly showed that his splenium was not present. The hemialexic had partially recovered at 9 years after the onset. The patient was 76% correct in Japanese phonogram words and 92% correct in ideogram words in an interfield same-different judgment, that is, judging whether 2 one-letter words, one in the left hemifield and the other in the right, were the same or different. Consequently, the possible mechanism for the recovery is that the transfer of visual word information from the right hemisphere to the left has been partially achieved by commissural fibers other than those of the splenium. Information from phonogram words in the right hemisphere is probably less transferred to the left hemisphere than that from ideogram words. The results also suggested that when the transfer of word information in the right hemisphere to the left is interfered with, the left hemisphere tends to mistake the same pair of words for the different pair.
