Young female violent death trends in the general population during the Vietnam era.

Five birth cohorts of young women who became age 20 before, during, and after the Vietnam War were selected for this study of motor vehicle accident, suicide, and homicide between ages 13 and 30. Suicide and homicide increased strongly in succeeding years (1953-1986). Motor vehicle accident rates were affected primarily by age. But age, birth cohort membership, and age x cohort interaction significantly affected suicide and homicide rates, with the 19-24-year-old age range most greatly affected. The correlation between suicide and homicide risk (r = .92) was similar to that for young males (r = .95) and suggested a common source of pathogenesis for both genders.

Selective copying of the majority suggests children are broadly “optimal‐” rather than “over‐” imitators

Human children, in contrast to other species, are frequently cast as prolific “over‐imitators”. However, previous studies of “over‐imitation” have overlooked many important real‐world social dynamics, and may thus provide an inaccurate account of this seemingly puzzling and potentially maladaptive phenomenon. Here we investigate this topic using a cultural evolutionary approach, focusing particularly on the key adaptive learning strategy of majority‐biased copying. Most “over‐imitation” research has been conducted using consistent demonstrations to the observer, but we systematically varied the frequency of demonstrators that 4‐ to 6‐year‐old children observed performing a causally irrelevant action. Children who “over‐imitate” inflexibly should copy the majority regardless of whether the majority solution omits or includes a causally irrelevant action. However, we found that children calibrated their tendency to acquire the majority behavior, such that copying did not extend to majorities that performed irrelevant actions. These results are consistent with a highly functional, adaptive integration of social and causal information, rather than explanations implying unselective copying or causal misunderstanding. This suggests that our species might be better characterized as broadly “optimal‐” rather than “over‐” imitators.     

Should We Take “Gender” Out of Gender Subtypes? The Effects of Gender,Evaluative Valence,and Context on the Organization of Person Subtypes

Previous research examining the organization of person subtypes has focused on gender and evaluation as organizing principles. Our research additionally examined subtype organization in terms of the classic “person categories” described in the self-concept and impression formation literature. Using both qualitative and quantitative measures, we examined the relative impact of these three mechanisms of subtype organization. We also investigated whether contextual cues impact subtype organization. We found that subtypes are more frequently organized in terms of person categories than by gender or evaluation. Also, as predicted, some subtype clusters' organization was relatively stable, whereas other subtype clusters were more sensitive to contextual influences. These results are discussed in terms of how characteristics that are salient in a situation may prime certain subtypes.     

Do apes and children know what they have seen?

Chimpanzees and young children understand much about what other individuals have and have not seen. This study investigates what they understand about their own visual perception. Chimpanzees, orangutans, and 2.5-year-old children were presented with a finding game in which food or stickers were hidden in one of two or three tubes. We varied whether subjects saw the baiting of the tubes, whether subjects could see through the tubes, and whether there was a delay between baiting and presentation of the tubes to subjects. We measured not only whether subjects chose the correct tube but also, more importantly, whether they spontaneously looked into one or more of the tubes before choosing one. Most apes and children appropriately looked into the tubes before choosing one more often when they had not seen the baiting than when they had seen the baiting. In general, they used efficient search strategies more often than insufficient or excessive ones. Implications of subjects' search patterns for their understanding of seeing and knowing in the self are discussed. Accepted after revision: 7 January 2001 Electronic Publication     

Further psychodrama with delinquent adolescents

It was postulated that an integration of behavioral-cognitive techniques within a psychodramatic group therapy framework would reduce delinquents' acting-out tendencies and improve ego strength. The population consisted of a control and an experimental group of adolescents aged 14 to 16 of both sexes that were adjudicated delinquent. There were ten adolescents in the control group and initially eleven adolescents in the experimental group (only seven completed the twelve ninety-minute sessions). Both pre- and posttest measures on the Jesness, the High School Personality Questionnaire, and the I-E Scale were administered to the two groups of subjects. The results showed that significant improvement occurred in the delinquents' asocial index (.01 level), ego strength (.05 level), and introversive tendencies (.01 level). This study demonstrated that behavioral contracting, monetary reinforcement, and alternative behavioral rehearsal can be effectively integrated with more traditional psychodramatic techniques to reduce delinquents' acting-out tendencies.     

Pictures in sentences: understanding without words

To understand a sentence, the meanings of the words in the sentence must be retrieved and combined. Are these meanings represented within the language system (the lexical hypothesis) or are they represented in a general conceptual system that is not restricted to language (the conceptual hypothesis)? To evaluate these hypotheses, sentences were presented in which a pictured object replaced a word (rebus sentences). Previous research has shown that isolated pictures and words are processed equally rapidly in conceptual tasks, but that pictures are markedly slower than words in tasks requiring lexical access. The lexical hypothesis would therefore lead one to expect that rebus sentences will be relatively difficult, whereas the conceptual hypothesis would predict that rebus sentences would be rather easy. Sentences were shown using rapid serial visual presentation (RSVP) at a rate of 10 or 12 words per second. With one set of materials (Experiments 1 and 2), readers took longer to judge the plausibility of rebus sentences than all-word sentences, although the accuracy of judgment and of recall were similar for the two formats. With two new sets of materials (Experiments 3 and 5), rebus and all-word sentences were virtually equivalent except in one circumstance: when a picture replaced the noun in a familiar phrase such as seedless grapes. In contrast, when the task required overt naming of the rebus picture in a sentence context, latency to name the picture was markedly longer than to name the corresponding word, and the appropriateness of the sentence context affected picture naming but not word naming (Experiment 4). The results fail to support theories that place word meanings in a specialized lexical entry. Instead, the results suggest that the lexical representation of a noun or familiar noun phrase provides a pointer to a nonlinguistic conceptual system, and it is in that system that the meaning of a sentence is constructed.
