Ethnocultural aspects of suicide in young people: a systematic literature review part 2: Risk factors, precipitating agents, and attitudes toward suicide

Different scholars have expressed the same regret for the lack of research on ethnocultural differences in youth suicide behavior and the need to conduct more comparative studies, necessary to develop culturally responsive prevention and intervention strategies. The authors reviewed 82 publications on youth suicide that have considered, to different degrees, the ethnicity/culture of the population studied. Part 1 of this article explored youth suicide rates and methods (SLTB, this issue), while the present paper examines risk and precipitating factors and attitudes toward suicide in young people from a cross-cultural perspective.     

Proprioception and Stimulus-Response Compatibility

Sixteen subjects pressed a left or right key in response to lateralized visual stimuli, in uncrossed (left index finger on left key, right finger on right key) and crossed conditions (left finger on right key and vice versa), with varying finger separations. Visual, tactile, or 'efference copy' cues about relative finger positions were unavailable. Subjects had to press the key on the same side as (compatible group) or opposite side to the stimulus (incompatible group). Separate proprioceptive judgements of the relative finger positions were obtained. Findings of an overall reaction time (RT) advantage for compatible instructions and for uncrossed hands were replicated. With decreasing finger separation the RT advantage for compatible instructions decreased, and the probability of responding with either hand increased. The compatibility effect disappeared completely at the 6-cm crossed position, not at the position that was hardest to judge proprioceptively. This suggests that two forms of neural activation are summed: automatic activation of the anatomically same-side limb, and an integrated, rule-based activation. The results further demonstrate that independent proprioceptive cues from each limb, unassociated with skin contact between the limbs, can mediate the determination of relative position for response selection in stimulus-response compatibility tasks.     

Interactional Reconstruction in Real-Time Language Processing

This study documents and characterizes a phenomenon in naturally-occurring conversation which I have termed interactional reconstruction. Interactional reconstruction involves retroactive reinterpretation of an earlier utterance (or set of utterances) on the basis of a more recent utterance (or set of utterances). This work is meant to serve two functions: first, to enrich our theories of human communication; and second, to explore directions and implications for theories of meaning and discourse modeling within cognitive science.     

Sex Differences Among Personality Correlates of Mathematical Ability in High School Seniors

To help explain female inferiority in mathematical performance, sex differences in personality correlates of mathematical ability were examined. Three instruments, Rotter's I-E Scale, Miller Adult Locus of Evaluation Scale, and Byrd's Attitude Concerning Life and Self were administered to measure four personality factors: locus of control, locus of evaluation, identity confusion associated with resolution of the adolescent identity crisis, and self-esteem. Each personality score was correlated separately by sex with Scholastic Aptitude Test mathematical and verbal scores. The sample included 68 females and 63 males, randomly selected from college-bound seniors in a predominantly white, middle-class, suburban high school, chosen to limit the effects of social, economic, racial and educational differences. Two variables were partialed out for control purposes: number of mathematics courses completed and IQ Otis-Lennon Mental Ability Test. For females only, internal locus of control and self-esteem were significant correlates of mathematical ability, and were seen as facilitators of female mathematical functioning in the face of environmental impediments to female mathematical performance.
