In‐court versus out‐of‐court testimonies: Children's experiences and adults' assessments

The study examined the effects of different presentation modes on child witnesses' experiences and adults' perception and assessments of the same witnesses. Child witnesses (N = 108) were interviewed about an event that they had either experienced or imagined. Adult mock jurors (N = 240) watched the children's testimonies live, via two‐way closed‐circuit television (CCTV), or via a pre‐recorded video. The results showed that the live observers perceived the children in more positive terms than did the two‐way CCTV observers, who in turn perceived the children in more positive terms than did the video observers. Briefly, it seems as the more proximal the presentation mode, the more positive the observers' perception. Somewhat in contrast to these results, a significantly smaller proportion of the children who testified on video stated that they were nervous, compared to the children who testified live or via two‐way CCTV.

Walking or talking? Behavioral and neurophysiological correlates of action verb processing

Brain activity elicited by visually presented words was investigated using behavioral measures and current source densities calculated from high-resolution EEG recordings. Verbs referring to actions usually performed with different body parts were compared. Behavioral data indicated faster processing of verbs referring to actions performed with the face muscles and articulators (face-related words) compared to verbs referring to movements involving the lower half of the body (leg-related words). Significant topographical differences in brain activity elicited by verb types were found starting approximately 250 ms after word onset. Differences were seen at recording sites located over the motor strip and adjacent frontal cortex. At the vertex, close to the cortical representation of the leg, leg-related verbs (for example, to walk) produced strongest in-going currents, whereas for face-related verbs (for example, to talk) the most in-going activity was seen at more lateral electrodes placed over the left Sylvian fissure, close to the representation of the articulators. Thus, action words caused differential activation along the motor strip, with strongest in-going activity occurring close to the cortical representation of the body parts primarily used for carrying out the actions the verbs refer to. Topographically specific physiological signs of word processing started earlier for face-related words and lasted longer for verbs referring to leg movements. We conclude that verb types can differ in their processing speed and can elicit neurophysiological activity with different cortical topographies. These behavioral and physiological differences can be related to cognitive processes, in particular to lexical semantic access. Our results are consistent with associative theories postulating that words are organized in the brain as distributed cell assemblies whose cortical distributions reflect the words' meanings.     

Development of cognitive averaging: when light and light make dark

In two experiments we studied developmental changes in reasoning about intensive quantities. In contrast to previous studies, color--an intensive quantity that is readily perceivable--was chosen as stimulus material. Children between 6 and 12 years of age and adults predicted the mixture intensity of pairs of liquids with different intensities of red color, the liquid volumes in the two source glasses either being the same (Experiment 1) or different (Experiment 2). The data show that cognitive averaging in this domain develops late and slowly. An extensitivity bias, a strong tendency to use rules (adding in particular) that hold for extensive but not for intensive quantities, predominated up to the age of 12 years and was not totally absent in adults. Contrary to common expectation, children's use of the correct averaging rule became more likely when an extensive quantity, volume, was also varied and thus the task increased in complexity.     

Is the mystery an illusion? Papineau on the problem of consciousness

A number of philosophers have recently argued that (i) consciousness properties are identical with some set of physical or functional properties and that (ii) we can explain away the frequently felt puzzlement about this claim as a delusion or confusion generated by our different ways of apprehending or thinking about consciousness. This paper examines David Papineau’s influential version of this view. According to Papineau, the difference between our “phenomenal” and “material” concepts of consciousness produces an instinctive but erroneous intuition that these concepts can’t co-refer. I claim that this account fails. To begin with, it is arguable that we are mystified about physicalism even when the account predicts that we shouldn’t be. Further, and worse, the account predicts that an “intuition of distinctness” will arise in cases where it clearly does not. In conclusion, I make some remarks on the prospects for, constraints on, and (physicalist) alternatives to, a successful defence of the claim (ii).     

When your heart is in your mouth: the effect of second language use on negative emotions

Research on bilingualism and emotions has shown stronger emotional responses in the native language (L1) compared to a foreign language. We investigated the potential of purposeful second language (L2) use as a means of decreasing the experience of psychological distress. Native Swedish speakers read and answered questions about negative and neutral texts in their L1 (Swedish) and their L2 (English) and were asked to rate their level of distress before or after the questions. The texts and associated questions were either written in the same (within-language), or different languages (cross-language). We found that within-language trials when the text was written in participants’ native language (Swedish–Swedish) resulted in an increase of distress, whilst cross-language trials (Swedish–English) resulted in a decrease of distress. This implies that purposeful second language use can diminish levels of distress experienced following a negative event encoded in one's first language.     

Beziehungsmuster und Beziehungskonflikte

Zusammenfassung  Die Veränderung pathogenetisch bedeutsamer Beziehungsmuster gilt als wesentliches psychotherapeutisches Behandlungsziel. Um zielgerichtete Veränderungen von Beziehungsstrukturen zu erreichen, bedarf es sowohl einer Diagnostik und Beschreibung solcher Beziehungsmuster, einer darauf zielenden Behandlungstechnik als auch einer Verlaufskontrolle und Evaluation der angestrebten Veränderungen. Nach einem Überblick über verschiedene Methoden zur Erfassung von Beziehungsmustern wird die Methode des Zentralen-Beziehungskonflikt-Themas (ZBKT) von Luborsky näher beschrieben; ausgewählte Ergebnisse der ZBKT-Forschung werden dargestellt und die Methode kritisch bewertet.

Is visual attention automatically attracted by one’s own name?

Subjects were presented with briefly exposed visual displays of words that were common first names with a length of four to six letters. In the main experiment, each display consisted of four words: two names shown in red and two shown in white. The subject’s task was to report the red names (targets), but ignore the white ones (distractors). On some trials the subject’s own name appeared as a display item (target or distractor). Presentation of the subject’s name as a distractor caused no more interference with report of targets than did presentation of other names as distractors. Apparently, visual attention was not automatically attracted by the subject’s own name.     

Spatial selection in peripheral letter recognition: in search of boundary conditions

Recognition performance for a peripherally presented target letter embedded in a letter string is worse than for targets presented in isolation. This lateral masking effect is commonly attributed to impairments when identifying flanked letters. The hypothesis that also failures during spatial selection of the target underlie lateral masking effects was examined by varying the brightness of the flankers (Experiment 1), by cueing the target position at various times before, during, or after presentation of the string (Experiment 2) and by avoiding the abrupt on- and offset of the flankers (Experiments 3 and 4). Whereas the flankers' brightness had no effect on and cueing only slightly reduced the lateral masking effects, it was substantially reduced by avoiding the abrupt on- and offset of the flankers. The results show that spatial selection is impaired in peripheral vision, and that this is one important factor underlying lateral masking effects.     

Physical activity,motor ability,and school readiness of 6-yr.-old children

The aim of this investigation was to study the relationships between physical activity, motor ability, and school readiness in 6-yr.-old children. In total, 294 healthy children from Tartu were studied (161 boys and 133 girls). The physical activity of children was reported by parents and teachers using the questionnaire of Harro. The motor ability of children was evaluated using various tests from the Eurofit test battery as well as the 3-min. endurance shuttle run test. The Controlled Drawing Observation rest was used as a predictor of school readiness and development of mental abilities. Indoor physical activities predicted 19-25% of total variance in motor scores for these preschool children. Motor ability tests, which demand children's total attention and concentration, appear related to the chosen measures of school readiness.
