Development of mental rotation in 3- to 5-year-old children

We assessed 3- to 5-year-olds’ mental rotation abilities using a new puzzle paradigm. It allows for assessment of mental rotation abilities in children younger than 5 years, using a task comparable to ones used with older children and adults. Children saw pairs of asymmetrical ghost figures, either as three-dimensional cut-outs or two-dimensional paper versions, in seven orientations. One of the ghosts fit into a hole if rotated right-side up – the other ghost was its mirror image and would not fit. Children were asked to turn the ghosts in their heads and choose the one that would fit into the hole. The number of children who chose the correct ghost above chance in the three-dimensional version of the task increased dramatically from 10% of 3-year-olds to 95% of 5-year-olds; average accuracy also increased significantly, from 54% to 83%. The two-dimensional paper version yielded similar results. These results indicate considerable development in mental rotation between 3 and 5 years.     

Motor Processes in Children's Mental Rotation

Previous studies with adult human participants revealed that motor activities can influence mental rotation of body parts and abstract shapes. In this study, we investigated the influence of a rotational hand movement on mental rotation performance from a developmental perspective. Children at the age of 5, 8, and 11 years and adults performed a mental rotation task while simultaneously rotating their hand (guided by a handle). The direction of the manual rotation was either compatible or incompatible with the direction of the mental rotation. Response times increased with increasing stimulus orientation angles, indicating that participants of all age groups used mental rotation to perform the task. A differential effect of the compatibility of manual rotation and mental rotation was found for 5-year-olds and 8-year-olds, but not for 11-year-olds and adults. The results of this study suggest that the ability to dissociate motor from visual cognitive processes increases with age.     

Resilience and successful community reintegration among female forensic psychiatric patients: a preliminary investigation

Research on resiliency and recovery in forensic psychiatric patients is still limited. Information pertaining to factors associated with successful community reintegration would contribute to a more comprehensive assessment of functioning and informed treatment planning that fits within a recovery approach of service provision. Using a retrospective design involving file reviews and a 3-year follow-up period, the authors investigated the rate of successful/unsuccessful community reintegration (defined by the presence or absence of an absolute discharge/readmission to hospital) in female forensic psychiatric patients (N = 48). The study evaluated the extent to which the risk and protective factors captured in the Short-Term Assessment of Risk and Treatability (START) predicted a range of positive and negative outcomes in the study sample. Results showed that 47.9% of the women qualified as having successfully reintegrated into the community, with the remaining 52.1% qualifying as still being in recovery. Successful individuals possessed significantly more protective factors and significantly fewer risk factors than individuals still in recovery. Furthermore, both the vulnerability and the strength scale of the START demonstrated good predictive validity, however we did not find evidence of incremental validity of the strength scale.

Gender differences in the assessment, stability, and correlates to bullying roles in middle school children

The current study investigated bullying behaviors in 284 school children in the fourth through seventh grades at the time of the initial assessment. Peer ratings of bullying behavior were obtained at the end of the spring semester of one school year and at the end of the fall semester of the next school year. Importantly, peer ratings were obtained by assessing not only the level at which participants actually bully other students but also whether participants help bullies to hurt the victim (assister), encourage bullies (reinforce), or help the victim of bullying (defender). Our results did not support the utility of differentiating between bullies, assisters, or reinforcers. Specifically, these bullying roles were highly intercorrelated, both concurrently and across school years, and they showed similar correlations with aggression and several characteristics often associated with aggression (i.e., conduct problems, callous-unemotional traits, and positive expectancies about aggression). In contrast, ratings of defending designated a particularly prosocial group of students. Finally, whereas bullying appeared to be very similar in boys and girls, it was somewhat more stable across school years and was related to lower levels of prosocial behavior in boys, both of which could suggest that bullying may be somewhat more related to social group dynamics in girls.     

Exemplarization and self-presentation: Lehrer and Meinong on consciousness

Alexius Meinong??s specific use of the term ??self-presentation?? had a significant influence on modern epistemology and philosophical psychology. To show that there are remarkable parallels between Meinong??s account of the self-presentation of experiences and Lehrer??s account of the exemplarization of experiences is one of this paper??s main objectives. Another objective is to put forward some comments and critical remarks to Lehrer??s approach. One of the main problems can be expressed by the following: The process of using a particular experience as a sample, that is, an exemplar that we use to stand for and refer to a plurality of experiences, Lehrer calls ??exemplarization??. As concrete experiences are multifarious (red and round, for example), how can we single out a specific sort of experiences (the red ones) by the process of exemplarization when we use such a multifarious experience as a sample?     

Violence Exposure Mediates the Relation Between Callous-Unemotional Traits and Offending Patterns in Adolescents

The link between callous-unemotional (CU) traits in youth and delinquent, aggressive and violent behavior is well-replicated in the literature. However, the mediating effects of violence exposure on this relationship are unclear. The current study addresses this important gap in the literature with a sample of 88 detained, primarily ethnic minority adolescent boys (M age?=?15.57; SD?=?1.28). Results indicate that exposure to violence fully mediated the relationship between CU traits and violent delinquency, and this pattern of mediation was accounted for by exposure to witnessed violence, but not direct violent victimization. Secondly, exposure to violence, both direct and witnessed forms, also mediated the relationship between CU traits and drug delinquency. These findings suggest that (a) the well-established link between CU traits and violence may be attributed to high rates of witnessed violence among this subpopulation, and (b) specific types of violence exposure may be important for predicting the offending patterns of youth high on CU traits. Theoretical and practical implications are discussed.     

Teaching World Religions without Teaching “World Religions”

Tomoko Masuzawa and a number of other contemporary scholars have recently problematized the categories of “religion” and “world religions” and, in some cases, called for its abandonment altogether as a discipline of scholarly study. In this collaborative essay, we respond to this critique by highlighting three attempts to teach world religions without teaching “world religions.” That is, we attempt to promote student engagement with the empirical study of a plurality of religious traditions without engaging in the rhetoric of pluralism or the reification of the category “religion.” The first two essays focus on topical courses taught at the undergraduate level in self‐consciously Christian settings: the online course “Women and Religion” at Georgian Court University and the service‐learning course “Interreligious Dialogue and Practice” at St. Michael's College, in the University of Toronto. The final essay discusses the integration of texts and traditions from diverse traditions into the graduate theology curriculum more broadly, in this case at Loyola Marymount University. Such confessional settings can, we suggest, offer particularly suitable – if somewhat counter‐intuitive – contexts for bringing the otherwise covert agendas of the world religions discourse to light and subjecting them to a searching inquiry in the religion classroom.     

Recency and the modality effect in immediate ordered recall

In immediate ordered recall, recency is the improved recall of the last item of a presentation, and the modality effect is the advantage for an acoustic presentation over a subvocalized visual presentation, primarily occurring at the last serial position. Experiment 1 tested grouped presentations. There was a modality effect for the first item of the last group, even though that item was at the third-to-last or fourth-to-last serial position. In Experiment 2, for vocalized presentations of syllables ending in a, recency was larger for staccato speech than legato speech; for subvocalized presentations, there was a substantial recency for the legato style. In Experiment 3, recency was larger for a set of syllables ending in ATE than for a set of syllables ending in AME. These results suggest that recency cannot be explained by the existence of a fixed-capacity store, auxiliary to the auditory short-term store, that retains only some types of presentations. It is suggested instead that recency might reflect an auxiliary method of using the information in the auditory short-term store.     

Attenuating the visual suffix effect with color

In previous studies using a short-duration visual presentation (200-340 msec), presentation of a different colored suffix did not attenuate the visual suffix effect. In Experiment 1, color attenuated the suffix effect for a longer duration visual presentation (approximately 3-4 sec) during which the subject engaged in articulatory suppression to prevent auditory recoding. Experiments 2 and 3 confirmed that color does not attenuate the suffix effect for the short-duration presentations. In Experiment 4, recall of a long-duration presentation was not improved when the last digit was a different color, suggesting that the different color of the suffix improves recall by allowing the suffix to be excluded from visual short-term memory. The attenuation by color is consistent with the hypothesis that preattentive grouping governs the entry of information into visual short-term memory.
