Functional equivalence of spatial representations derived from vision and language: evidence from allocentric judgments

Past research (e.g., J. M. Loomis, Y. Lippa, R. L. Klatzky, & R. G. Golledge, 2002) has indicated that spatial representations derived from spatial language can function equivalently to those derived from perception. The authors tested functional equivalence for reporting spatial relations that were not explicitly stated during learning. Participants learned a spatial layout by visual perception or spatial language and then made allocentric direction and distance judgments. Experiments 1 and 2 indicated allocentric relations could be accurately reported in all modalities, but visually perceived layouts, tested with or without vision, produced faster and less variable directional responses than language. In Experiment 3, when participants were forced to create a spatial image during learning (by spatially updating during a backward translation), functional equivalence of spatial language and visual perception was demonstrated by patterns of latency, systematic error, and variability.     

Use of cognitive versus perceptual heading during imagined locomotion depends on the response mode

Three experiments investigated whether the systematic errors previously observed in a triangle-completion task were caused by failures to form and update a cognitive heading or by use of perceived heading (even though an updated cognitive heading was available) during the response. These errors were replicated when participants indicated the origin of triangular paths they had imagined walking by turning their bodies toward the origin, but not when they responded verbally. The results indicate that participants are capable of updating their cognitive heading using imagined movements and suggest that the systematic errors previously observed were a result of the strong attachment of responses such as turns to a perceptual representation of the physical body.     

Spatial frameworks in imagined navigation

The spatial framework model proposes that people use the extensions of their body axes as a reference frame for encoding spatial layouts in memory, and that the physical and functional properties of our bodies and the world determine the accessibility of egocentric locations from memory representations. The present experiment provides evidence that spatial framework results can be obtained even with perceptual scenes that contain no objects to be held in memory. Using a paradigm in which participants interpreted direction and distance information to follow a mental path within a checkerboard grid, the present study shows that spatial framework results are obtained when reasoning occurs from a perspective that is misaligned with respect to the physical reference frame of the participant. The theoretical implications of these results are discussed.     

Startle modulation during violent films: Association with callous–unemotional traits and aggressive behavior

The current study examined the unique and interactive associations of callous–unemotional (CU) traits, impulsive and premeditated aggression with startle modulation to violent films. Eighty-five participants (Mage = 20.52) at differential risk of CU traits, selected from a sample of 1105 young adults, participated in the physiological experiment. Startle eye-blink responses to acoustic probes were recorded during violent, comedy and neutral films. Self-report ratings of valence and arousal were also collected. Findings from regression analysis documented that CU traits were associated with diminished startle potentiation to violent films, whereas impulsive aggression was associated with increases in startle potentiation. Further, the negative association between CU traits with startle potentiation, valence, and arousal ratings to violent films was moderated by impulsive aggression. At the group level, individuals high on impulsive aggression without CU traits were the ones showing the highest levels of startle potentiation to violent films, and scored on the opposite extreme compared to individuals high on both CU traits and impulsive aggression.     

Desensitization to media violence over a short period of time

This study investigated the desensitization to violence over a short period of time. Participants watched nine violent movie scenes and nine comedy scenes, and reported whether they enjoyed the violent or comedy scenes and whether they felt sympathetic toward the victim of violence. Using latent growth modeling, analyses were carried out to investigate how participants responded to the different scenes across time. The findings of this study suggested that repeated exposure to media violence reduces the psychological impact of media violence in the short term, therefore desensitizing viewers to media violence. As a result, viewers tended to feel less sympathetic toward the victims of violence and actually enjoy more the violence portrayed in the media. Additionally, desensitization to media violence was better represented by a curvilinear pattern, whereas desensitization to comedy scenes was better represented by a linear pattern. Finally, trait aggression was not related to the pattern of change over time, although significant effects were found for initial reports of enjoyment and sympathy. Aggr.

Assessing the Dimensionality and Other Psychometric Properties of a Greek Translation of the Sex-role Egalitarianism Scale (Form B)

The main purpose of this study was to investigate the dimensionality of a Greek-language version of the Sex Role Egalitarianism Scale—Form B (SRES-B) via confirmatory factor analysis. Using two different samples (undergraduates and community sample from Greece) data from 667 individuals were collected. Three models were specified: the five-factor model (marital, parental, social–interpersonal–heterosexual, employment, and educational roles); the two-factor model (Intimate and Formal); and the single-factor model (Global factor). The findings indicated that the two-factor model had the best fit. The corresponding alpha coefficients were .94 and .92 respectively, with .96 for the total scale. Results also showed that women, young individuals, well educated persons, and people residing in cities were more egalitarian. No differences between the two samples were found.     

Multiple systems of spatial memory and action

Recent findings from spatial cognition and cognitive neuroscience suggest that different types of mental representations could mediate the off-line retrieval of spatial relations from memory and the on-line guidance of motor actions in space. As a result, a number of models proposing multiple systems of spatial memory have been recently formulated. In the present article we review these models and we evaluate their postulates based on available experimental evidence. Furthermore, we discuss how a multiple-system model can apply to situations in which people reason about their immediate surroundings or non-immediate environments by incorporating a model of sensorimotor facilitation/interference. This model draws heavily on previous accounts of sensorimotor interference and takes into account findings from the stimulus-response compatibility literature.     

The Effects of a Cooperative Physical Education Program on Students’ Social Skills

The present study examined the effect of a cooperative physical education program on students’ social skills and attitudes toward group work. Four sixth grade classes were assigned either in an experimental (n = 57) or in a control group (n = 57). The experimental classes received a cooperative learning program. Students completed self- and peer forms of the Multisource Assessment of Children's Social Competence (Junttila, Voeten, Kaukiainen, & Vauras, 2006 Junttila, N., Voeten, M., Kaukiainen, A. and Vauras, M. 2006. Multisource assessment of children‘s social competence. Educational and Psychological Measurement, 66: 876–895.  [Google Scholar]) and the Feelings Toward Group Work scales (Cantwell & Andrews, 2002 Cantwell, R. H. and Andrews, B. 2002. Cognitive and psychological factors underlying secondary school students’ feelings towards group work. Educational Psychology, 22: 75–91. [Taylor & Francis Online] , [Google Scholar]) before and after the program. Results showed gains of the experimental classes on social skills and on preferences for group work.     

Sensorimotor alignment effects in the learning environment and in novel environments

Four experiments investigated the conditions contributing to sensorimotor alignment effects (i.e., the advantage for spatial judgments from imagined perspectives aligned with the body). Through virtual reality technology, participants learned object locations around a room (learning room) and made spatial judgments from imagined perspectives aligned or misaligned with their actual facing direction. Sensorimotor alignment effects were found when testing occurred in the learning room but not after walking 3 m into a neighboring (novel) room. Sensorimotor alignment effects returned after returning to the learning room or after providing participants with egocentric imagery instructions in the novel room. Additionally, visual and spatial similarities between the test and learning environments were independently sufficient to cause sensorimotor alignment effects. Memory alignment effects, independent from sensorimotor alignment effects, occurred in all testing conditions. Results are interpreted in the context of two-system spatial memory theories positing separate representations to account for sensorimotor and memory alignment effects.
