How schoolchildren’s acceptance of self and others relate to their attitudes to victims of bullying

Previous research has indicated that harm to the mental health of children who are repeatedly victimised by their peers at school can be ameliorated through social or emotional support provided by other students. In this study we examined whether student provictim attitudes are related to more basic attitudes to self and attitudes to others. Measures of these attitudes were developed for use with children, and shown to be internally consistent and possess concurrent validity. Relations between these variables were then examined with a sample of Australian school children ( $N = 212$ ) aged between 9 and 14 years. Provictim attitudes correlated significantly ( $r = .55$ ) with acceptance of others, but not with acceptance of self ( $r = -.04$ ). Controlling for age and gender, multiple regression analyses confirmed these findings. Attitudes to victims were less positive for older students ( $r = -.22$ ). Gender differences, however, were not significant. These findings suggest that among schoolchildren self-acceptance is unrelated to positive attitudes towards victims, whereas acceptance of others has a moderately strong relation with provictim attitude. Implications for improving attitudes to victims among school children were examined.     

Integrating conceptual knowledge within and across representational modalities

Research suggests that concepts are distributed across brain regions specialized for processing information from different sensorimotor modalities. Multimodal semantic models fall into one of two broad classes differentiated by the assumed hierarchy of convergence zones over which information is integrated. In shallow models, communication within- and between-modality is accomplished using either direct connectivity, or a central semantic hub. In deep models, modalities are connected via cascading integration sites with successively wider receptive fields. Four experiments provide the first direct behavioral tests of these models using speeded tasks involving feature inference and concept activation. Shallow models predict no within-modal versus cross-modal difference in either task, whereas deep models predict a within-modal advantage for feature inference, but a cross-modal advantage for concept activation. Experiments 1 and 2 used relatedness judgments to tap participants’ knowledge of relations for within- and cross-modal feature pairs. Experiments 3 and 4 used a dual-feature verification task. The pattern of decision latencies across Experiments 1–4 is consistent with a deep integration hierarchy.     

Angle illusion in a straight road

We report a new angle illusion observed when viewing a real scene involving a straight road. The scene portrays two white lines which outline a traffic lane on a road and converge to a vanishing point. In experiment 1, observers estimated the angle created by these converging lines in this scene or in its image projected onto a screen. Results showed strong underestimation of the angle, ie over 50% for observations of both the real scene and its projected image. Experiment 2 assessed how depth cues in projected images influence the angle illusion. Results showed that this angle illusion disappeared when scene information surrounding convergent lines was removed. In addition, the illusion was attenuated with projection of an inverted scene image. These findings are interpreted in terms of a misadoption of depth information in the processing of angle perception in a flat image; in turn, this induces a massive angle illusion.     

SenseCam: a wearable camera that stimulates and rehabilitates autobiographical memory

SenseCam is a wearable digital camera that captures an electronic record of the wearer's day. It does this by automatically recording a series of still images through its wide-angle lens, and simultaneously capturing a log of data from a number of built-in electronic sensors. Subsequently reviewing a sequence of images appears to provide a powerful autobiographical memory cue. A preliminary evaluation of SenseCam with a patient diagnosed with severe memory impairment was extremely positive; periodic review of images of events recorded by SenseCam resulted in significant recall of those events. Following this, a great deal of work has been undertaken to explore this phenomenon and there are early indications that SenseCam technology may be beneficial to a variety of patients with physical and mental health problems, and is valuable as a tool for investigating normal memory through behavioural and neuroimaging means. Elsewhere, it is becoming clear that judicious use of SenseCam could significantly impact the study of human behaviour. Meanwhile, research and development of the technology itself continues with the aim of providing robust hardware and software tools to meet the needs of clinicians, patients, carers, and researchers. In this paper we describe the history of SenseCam, and the design and operation of the SenseCam device and the associated viewing software, and we discuss some of the ongoing research questions being addressed with the help of SenseCam.     

SenseCam improves memory for recent events and quality of life in a patient with memory retrieval difficulties

A wearable camera that takes pictures automatically, SenseCam, was used to generate images for rehearsal, promoting consolidation and retrieval of memories for significant events in a patient with memory retrieval deficits. SenseCam images of recent events were systematically reviewed over a 2-week period. Memory for these events was assessed throughout and longer-term recall was tested up to 6 months later. A written diary control condition followed the same procedure. The SenseCam review procedure resulted in significantly more details of an event being recalled, with twice as many details recalled at 6 months follow up compared to the written diary method. Self-report measures suggested autobiographical recollection was triggered by the SenseCam condition but not by reviewing the written diary. Emotional and social wellbeing questionnaires indicated improved confidence and decreased anxiety as a result of memory rehearsal using SenseCam images. We propose that SenseCam images provide a powerful boost to autobiographical recall, with secondary benefits for quality of life.     

Same-sex patterns and sex differences in the trust-value basis of children's friendship

Thirty-six children in fourth grade were required (a) to report the secret-sharing, secret-keeping, promise-making, and promise-keeping behaviors of classroom peers; and (b) to judge those classmates on trust and friendship. Teachers provided observations of the children's friendship interaction. Same-sex patterns were found in observed friendship, friendship ratings, trust, secrets shared, proportion of secrets kept, and promises made. These were less frequent/lower for opposite-sex peers than for same-sex peers. As expected, males tended to share fewer secrets with same-sex peers than did females. The expected associations were found among proportion of secrets kept, proportion of promises kept, trust, and rated or observed friendship in females but with one exception in males. The findings supported the conclusion that same-sex friendship patterns are maintained by same-sex trust patterns through (a) infrequent secret sharing with opposite-sex peers and (b) the perception that opposite-sex peers break secrets more frequently than same-sex peers. The findings also supported the conclusion that there are some sex differences in the intimacy/trust basis of friendship.     

On the nature of neutral primes in a lexical decision task

Summary Research concerned with semantic priming has used a neutral prime as a benchmark for measuring the amount of facilitation for related targets and the amount of inhibition for unrelated targets. Recently, de Groot, Thomassen, and Hudson (1982) have reported that lexical decisions to targets are faster when preceded by the neutral prime BLANK as compared to a neutral prime consisting of a string of X's. Additionally, Antos (1979) has reported that an X neutral prime induces an inhibitory effect when the stimulus-onset-asynchrony (SOA) is short. The present experiment manipulated class of neutral prime, SOA, and practice. The results failed to support the observation by Antos. However, the results did support the finding by de Groot et al. at shorter SOA's (200 and 550 ms). At a longer (1000 ms) SOA the effect of the two neutral primes as well as the effect of the unrelated primes were equivalent. Practice had no differential effect on either of the neutral primes as compared to the unrelated priming conditions. These results were interpreted to mean that the difference between the two neutral primes at a brief SOA were perceptual in origin and that an unrelated word prime is neutral with respect to the target in the absence of strategic priming effects.     

The relation between syllable number and visual complexity in the acquisition of word meanings

Four experiments were conducted to explore the correlation between syllable number and visual complexity in the acquisition of novel words. In the first experiment, adult English speakers invented nonsense words as names for random polygons differing in visual complexity. Visually simple polygons received names containing fewer syllables than visually complex polygons did. In addition, analyses of English word-object pairings indicated that a significant correlation between syllable number and visual complexity exists in the English lexicon. In Experiments 2 and 3, adult English speakers matched monosyllabic novel words more often than trisyllabic novel words with visually simple objects, whereas trisyllabic matches were more common for visually complex objects. Experiment 4 replicated these findings with children, indicating that the assumption of a correlation between word and visual complexity exists during the period of intense vocabulary growth. Although the actual correlation between syllable number and visual complexity is small, other posited constraints on word meaning are also limited in strength. However, an increasing number of small, language-specific word-meaning correlations are being uncovered. Given the documented ability of speakers to detect and use these subtle correlations, we argue that a more fruitful approach to word-meaning acquisition would forgo the search for a few broad, powerful word-meaning constraints, and we attempt to uncover individually weak, but perhaps jointly powerful word-meaning correspondences.
