This study explores the trajectory of suicidal ideation in childhood and adolescence and identifies its strong predictors. Secondary data obtained from two nationally representative cohorts of South Korean youth were longitudinally analyzed using frequencies, percentages, and discrete time survival analysis. This study revealed an increase in the occurrence of suicidal ideation in adolescence, a higher prevalence of suicidal ideation among females than among males, and differences in predictors of suicide ideation by developmental stages and gender. The results suggest that multifaceted factors specific to developmental stages and gender should be simultaneously considered to diminish the occurrences of suicidal ideation. 相似文献

This study tests the effect of long‐term artificial development of a robot on users' feelings of social presence and social responses toward the robot. The study is a 2 (developmental capability: developmental versus fully matured) × 2 (number of participants: individual versus group) between‐subjects experiment (N= 40) in which participants interact with Sony's robot dog, AIBO, for a month. The results showed that the developmental capability factor had significant positive impacts on (a) perceptions of AIBO as a lifelike creature, (b) feelings of social presence, and (c) social responses toward AIBO. The number of participants factor, however, affected only the parasocial relationship and the buying intention variables. No interaction between the two factors was found. The results of a series of path analyses showed that feelings of social presence mediated participants' social responses toward AIBO. We discuss implications of the current study on human–robot interaction, the computers are social actors (CASA) paradigm, and the study of (tele)presence. 相似文献

This study tested implications of the context switching perspective proposed by Hamby, Ickes, and Babcock (2016). Using trained raters to assess the amount of reframing required to interpret the meaning of the subsequent (second) item within all adjacent item pairs, we first established that this process variable could be measured reliably. Then, in the data for 18 personality measures drawn from 3 individual-difference domains, we found that the amount of reframing (i.e., context switching) needed to interpret successive items predicted both lower interitem correlations and a greater percentage of misresponders. Similarly, item pairs that were mismatched in “directional” wording also predicted both lower interitem correlations and more misresponders. Finally, item pairs representing different factors predicted lower interitem correlations. Although the effects of direction switching and factor switching were partially mediated by the amount of reframing required, they remained significant even when the mediating effect of reframing was statistically controlled. These results indicate that interpreting the meaning of test items is a task for which the level of difficulty can vary with each successive item, as a function of how the current item compares to the previous item in aspects such as its context generality or specificity, directional wording, and content domain. 相似文献

Two experiments are reported that investigate the response structure and effector transfer of repeated movement sequences. Participants moved a lever to targets sequentially presented on the computer monitor. In Experiment 1 the learning of 10- and 16-element sequences (identical movement pattern) was contrasted. After 1 day of practice the 10-element sequence was organized into fewer subsequences and, thus, performed more rapidly than the 16-element sequence. The imposed organization appeared to be coded in a relatively abstract way, as evidenced by effector transfer that was as good as that on the retention test. In Experiment 2 the 16-element sequence was studied after more extensive practice. By the end of 4 days of practice the participants produced relatively seamless responses void of obvious transitions between subsequences, but the control of the movement was less effector independent than observed earlier in practice. The results suggest that the process of consolidating the sequence, which led to more fluent response production, also resulted in the utilization of effector specific information. 相似文献

Self‐construal is thought to mediate and explain the effects of culture on a wide variety of outcome variables. A meta‐analysis of published cross‐cultural self‐construal research is reported in this article, and the results across studies suggests that the evidence for the predicted cultural differences is weak, inconsistent, or nonexistent. The results of 3 priming experiments (N = 121, N = 99, and N = 361) suggest that (a) priming does not account for the inconsistent results observed in the meta‐analysis, (b) that scores on a self‐construal scale appear to be measuring trait‐like constructs that are not sensitive to priming, and (c) that measures of self‐construals lack convergent validity. The results of several measurement studies (N = 121, 223, 230, 323, 214, 206, 126, 204, 148, 141, and 150) were inconsistent with the a priori two‐factor measurement model in every case. Self‐construal scales were found to be radically multidimensional and highly unstable within and across cultures. These results lead us to conclude that catastrophic validity problems exist in research involving the use of self‐construal scales in cross‐cultural research. 相似文献

This study investigated the effects of a Men as Allies‐based intervention on high school students' rape‐supportive attitudes and behaviors. As hypothesized at posttest, the male and female experimental groups demonstrated a significant decrease in rape‐supportive attitudes, which was maintained at follow‐up. Male participants viewed peers' attitudes toward sexual violence as significantly different (worse) from peers' pretest self‐ratings; after intervention, male and female experimental group participants' peer ratings were significantly more accurate. 相似文献

A Multimethod Multitrait Validity Assessment of Self‐Construal in Japan,Korea, and the United States

A large number of previous studies have used self‐construal to predict communication outcomes. Recent evidence, however, suggests that validity problems may exist in self‐construal measurement. The current study conducted a multimethod multitrait (Campbell & Fiske, 1959) validation study of self‐construal measures with data (total N= 578) collected in Korea (N= 200), Japan (N= 212), and the U.S. (N= 166). The data showed that the Singelis (1994) Self‐Construal Scale, the Cross, Bacon, and Morris (2000) Relational Interdependent Self‐Construal Scale (RISC), and the Kuhn and McPartland (1954) Twenty Statements Test (TST) lacked convergent and discriminant validity, both pan‐culturally and within each of the three countries included in the study. Scores on the TST were not significantly related to scores on the self‐construal scales, and the various self‐construal measures correlated more highly with measures of communication directness than with alternative measures of the same type of self‐construal. Substantial method effects were also observed. The results were tested for both 2‐ and 3‐dimensional models of self‐construal and for refined scales and scales with all items retained. The results of all analyses were inconsistent with the claim that self‐construal measures are construct valid. 相似文献
