A field study exposed 235 high school students to anti‐smoking advertisements over a five‐month period to test the effectiveness of short‐term cosmetic versus long‐term health fear appeals in preventing or reducing smoking. The study was a longitudinal experiment with two experimental groups and a control group. Smoking behaviour was measured prior to message exposure on television, in magazines and on the internet, and at the end of the study period. The primary results were that average smoking declined for subjects exposed to either type of anti‐smoking fear appeal but not for the control group and short‐term cosmetic fear appeals were more effective for males but long‐term health fear appeals were more effective for females.

The collateral effects of response blocking were evaluated while treating stereotypic behavior in a woman diagnosed with autism. Blocking stereotypic behavior (head and tooth capping) was associated with decreases in leisure-item interaction and increases in another stereotypic response (hand wringing). Results suggested that the reduction in item interaction was due to adventitious punishment. Prompts to access an alternative source of reinforcement attenuated the side effects somewhat, but results suggested that the undesirable effects of response blocking may be fairly durable.  相似文献

Rough and tumble (R&T) play is a unique set of behaviors that can be reliably distinguished from aggression and other childhood activities. Although it may be the most fundamental form of play, it has received comparatively little experimental attention in the human species. Forty children, ages three to six, were allowed to play in pairs (10 male pairs, 10 female pairs) during a 30 minute videotaped session with no toys available while music played in the background during every other five‐minute time period. The incidence frequency of children's play and related behavioral activities were scored using 20 behavioral categories. The major findings show only modest gender differences in the frequency of play behaviors in such controlled social encounters; the main difference is that boys engaged in slightly more physical play solicitations than girls. Music facilitated General Motor Activities (e.g., Running and Walking behaviors), but not specific R&T play actions (e.g., Wrestling, Ventral and Dorsal contacts). Finally, most play behaviors as well as general activities declined systematically over the course of each recording session. This experiment highlights how human social play can be systematically studied in a controlled laboratory setting. Aggr. Behav. 29:539–551, 2003. © 2003 Wiley‐Liss, Inc.  相似文献

This paper examines the occurrence of framing effects when more thought is given to problems. In Study 1, participants were presented with one of two frames of several decision problems. Participants' Need for Cognition (NC) scores were obtained, and half the participants were asked to justify their choices. Substantial framing effects were observed, but the amount of thought purportedly given to a problem, whether manipulated by justification elicitation or measured by NC scores, did not reduce the incidence of framing effects. In Study 2, participants responded to both frames of problems in a within‐subjects design. Again, NC scores were unrelated to responses on the first frame encountered. However, high‐NC, compared to low‐NC, participants were more consistent across frames of a problem. More thought, as indexed here, does not reduce the proclivity to be framed, but does promote adherence to normative principles when the applicability of those principles is detectable.

We report three studies in which methodologies from psychophysics are adapted to investigate context effects on individual financial decision‐making under risk. The aim was to determine how the range and the rank of the options offered as saving amounts and levels of investment risk influence people's decisions about these variables. In the range manipulation, participants were presented with either a full range of choice options or a limited subset, while in the rank manipulation they were presented with a skewed set of feasible options. The results showed that choices are affected by the position of each option in the range and the rank of presented options, which suggests that judgments and choices are relative.

Ronald Reagan enjoyed a successful political career. Nevertheless, his political life was affected dramatically by the fact that he was the son of an alcoholic parent. Alcoholic parents leave deep marks on their children's lives, even after those children become adults. As president of the United States, Reagan clearly demonstrated these marks. He was aloof and distant, was often a disengaged leader, showed inordinate loyalty to associates even when such loyalty became problematic, was prone to live in a world of make‐believe, married compulsive women, and craved approval and applause. Each of these behavioral characteristics was part of the psychological legacy left to this president by his long‐dead alcoholic father. Some of them damaged his presidency greatly; others, however, may well have assisted it.  相似文献

This study examined the effects of perceived and actual social inclusion on health across and within individuals from a network perspective. During the first semester, 75 freshmen students provided bi-weekly ratings on their perceived social inclusion and health. To capture actual social inclusion, each student nominated liked and disliked fellow students. Perceived social inclusion mediated the effect of actual social inclusion on health. Specifically, students with more ‘likes’ perceived more social inclusion and those with higher perceived inclusion reported a better health status (between-person effect). In addition, at time points, when students received more ‘likes’ they also perceived more social inclusion. They reported better health at times when they felt more included (within-person effect). Thus, the perception of social inclusion is rooted in reality and actual social inclusion has an impact on health when passing the filter of perception.  相似文献

It is possible to reveal and to examine the collective and social fields of consciousness experimentally. An account is given of planned experiments based on quantitative calculations, which indicate that the effects of individual and collective fields of consciousness on matter may elicit directly observable physical results. Moreover, it is shown that collective coherent consciousness fields may enhance the physical effects of consciousness at a significant rate. The predicted results have a significance in our picture of our consciousness, in self‐assertion and dynamising of consciousness, the expansion of collective fields of consciousness, and thus the raising of the level of consciousness for humanity.  相似文献

This study examined the perceived psychosocial functions of flashbulb memories: It compared positive and negative public flashbulb memories (positive: Bin Laden's death, negative: Michael Jackson's death) with private ones (positive: pregnancy, negative: death of a loved one). A sample of n = 389 young and n = 176 middle-aged adults answered canonical category questions used to identify flashbulb memories and rated the personal significance, the psychological temporal distance, and the functions of each memory (i.e., self-continuity, social-boding, directive functions). Hierarchical regressions showed that, in general, private memories were rated more functional than public memories. Positive and negative private memories were comparable in self-continuity and directionality, but the positive private memory more strongly served social functions. In line with the positivity bias in autobiographical memory, positive flashbulb memories felt psychologically closer than negative ones. Finally, middle-aged adults rated their memories as less functional regarding self-continuity and social-bonding than young adults. Results are discussed regarding the tripartite model of autobiographical memory functions.  相似文献
