Suicidal ideation is defined as the thoughts about engaging in suicidal-related behaviors. Very few studies have been conducted on children’s suicidal ideation as there is a biased perception that suicidal behavior under the age of 12 is scarce. However, suicide is the leading cause of death among young children. Child suicidal ideation is predictive of suicidal ideation and suicide attempts in adulthood. Association between certain parenting styles and suicidal ideation have been found in empirical studies. However, little is known about the role of parenting and suicidal ideation in Chinese young children. We examined whether gratitude can reduce the risk of suicide by moderating the association between parenting styles and child suicidal ideation. We recruited 447 Chinese children (53.3% female; mean age?=?10.06, SD?=?1.76) to participate in a survey. Perceived parenting style (warmth/accepting, dominating, and autonomy granting), gratitude, and suicidal ideation were assessed using self-reported measures. We found that all three perceived parental styles were significantly associated with child suicidal ideation. Further, gratitude was found to have a significant moderating effect on suicidal ideation, across the analysis of the three perceived parenting styles. This suggests that gratitude may be adopted in preventive and clinical interventions so that children at risk can benefit from reducing the negative effects of ineffective parenting styles and suicidal ideation. 相似文献

Many online game players spend inordinate amounts of time in their favorite virtual worlds. A large percentage of these players are teenagers who show behaviors normally associated with physical addiction. Parents, educators, and social scientists are therefore saying that online games are sources of social problems. The authors surveyed 174 Taiwanese college-age online players to collect data on the potential effects of online games on the quality of interpersonal relationships and levels of social anxiety. According to the results, the quality of interpersonal relationships decreased and the amount of social anxiety increased as the amount of time spent playing online games increased. 相似文献

The present field experiment examined how multi-trial visuo-spatial learning and memory performance are impacted by excessive
arousal, instigated by a potentially life-threatening event (i.e., a first parachute jump). Throughout a parachute training
activity, subjective and neuroendocrine (i.e., cortisol) stress levels were assessed of 61 male military cadets who were randomly
assigned to a control (n = 30) or a jump stress condition (n = 31). Post-stress learning and memory capacity was assessed with a 10-trial path-learning task that permitted emergence
of learning curves. Pre-activity cortisol concentrations indicated a significant neuroendocrine anticipatory stress response
in the stress group. Following parachuting, subjective stress levels and salivary cortisol reactivity differed significantly
between groups. Visuo-spatial path-learning performance was impaired significantly after jump stress exposure, relative to
the control group. Moreover, examination of the learning curves showed similar learning and memory performance at onset of
the trials, with curves bifurcating as the task became more complex. These findings are in accordance with leading theories
that acknowledge a moderating effect of task complexity. In sum, the present study extends knowledge concerning anticipatory
stress effects, endogenously instigated cortisol reactivity, and the influence of extreme arousal on visuo-spatial path learning. 相似文献

The Character-Component Analysis Toolkit (C-CAT) software was designed to assist researchers in constructing experimental
materials using traditional Chinese characters. The software package contains two sets of character stocks: one suitable for
research using literate adults as subjects and one suitable for research using schoolchildren as subjects. The software can
identify linguistic properties, such as the number of strokes contained, the character-component pronunciation regularity,
and the arrangement of character components within a character. Moreover, it can compute a character’s linguistic frequency,
neighborhood size, and phonetic validity with respect to a user-selected character stock. It can also search the selected
character stock for similar characters or for character components with user-specified linguistic properties. 相似文献

A number of recent papers have suggested that the series of time intervals produced in continuation tapping may have fractal properties. This proposition, nevertheless, was only based on the visual appraisal of graphical results, and was not statistically supported. In the present study, we applied the ARMA/ARFIMA modeling procedures proposed by Wagenmakers, Farrell, and Ratcliff (2005) to test for the presence of long-range dependencies in continuation tapping data. Our results demonstrate the presence of long-range dependencies in most series and offer strong support for the hypothesis that fluctuations in tapping series are fractal in nature. 相似文献

The objective of this research is to show that, under usual conditions of interaction between an agent of health and of its public intervention, the individuals produce a “pro-health” speech which can lead astray this agent, concerning the representation which they have of alcohol. Students, producing verbal associations about this object, were confronted either with an agent of health or with a student, and were speaking either for themselves or as the students would do in general. The results show that the individuals, placed in front of an agent of health and directly implied in the beliefs that they express, tend to adopt the speech wished by this agent. However, this manifest adhesion only appears to be circumstantial, insofar as the speech of the individuals is different when they are expressed vis-a-vis a member of its group and in the name of this one. The implications of these results with regard to the interventions of prevention are discussed. 相似文献

Reasonning in naive set theory (with unlimited comprehension), we derive a paradox (a formal contradiction) which can be seen
as a variant of the Burali-Forti paradox.

The ability to compute probability, previously shown in nonverbal infants, apes, and monkeys, was examined in three experiments with pigeons. After responding to individually presented keys in an operant chamber that delivered reinforcement with varying probabilities, pigeons chose between these keys on probe trials. Pigeons strongly preferred a 75% reinforced key over a 25% reinforced key, even when the total number of reinforcers obtained on each key was equated. When both keys delivered 50% reinforcement, pigeons showed indifference between them, even though three times more reinforcers were obtained on one key than on the other. It is suggested that computation of probability may be common to many classes of animals and may be driven by the need to forage successfully for nutritional food items, mates, and areas with a low density of predators. 相似文献
