Media violence continues to be a concern to parents, policy makers and researchers. In spite of confidence expressed by some that exposure to television violence causes serious aggression and violent crime, critics hold that serious flaws in research methodology limits or nullifies conclusions drawn from widely-cited studies. In this paper, we will examine a series of classic studies for lessons learned about conducting media violence research, and assess whether recent publications adhere to those standards. We conclude that empirical reports with serious flaws continue to be published, compromising our ability to understand this phenomenon.  相似文献

The goal of the current study was to examine the predictive relationships among a set of cognitive-motivational variables that have been found in previous studies to support academic achievement. Student perception of a classroom’s achievement goal structure (classroom mastery, classroom performance-approach, classroom performance-avoidance) was used as the primary set of predictor variables, while student perceptions of belonging and subject matter instrumentality were used as dependent variables. There were 227 participants in the current study each of whom were enrolled in a rural high school in the Midwestern United States. Results indicated that the classroom level goal orientation was, in fact, predictive of belonging and perceived instrumentality. Specifically, classroom mastery goals and classroom performance-approach goals were found to positively relate to both belonging and perceived instrumentality. Implications of the aforementioned relationships are discussed.  相似文献

Section 1 of this essay distinguishes between four interpretations of Socratic intellectualism, which are, very roughly: (1) a version in which on any given occasion desire, and then action, is determined by what we think will turn out best for us, that being what we all, always, really desire; (2) a version in which on any given occasion action is determined by what we think will best satisfy our permanent desire for what is really best for us; (3) a version formed by the assimilation of (2) to (1), labelled the ??standard?? version?? by Thomas C. Brickhouse and Nicholas D. Smith, and treated by them as a single alternative to their own interpretation; and (4) Brickhouse and Smith??s own version. Section 2 considers, in particular, Brickhouse and Smith??s handling of the ??appetites and passions??, which is the most distinctive feature of interpretation (4). Section 3 discusses Brickhouse and Smith??s defence of ??Socratic studies?? in its historical context, and assesses the contribution made by their distinctive interpretation of ??the philosophy of Socrates??. One question raised in this section, and one that is clearly fundamental to the existence of ??Socratic studies??, is how different Brickhouse and Smith??s Socrates turns out to be from Plato himself, i.e., the Plato of the post-??Socratic?? dialogues; to which the answer offered is that on Brickhouse and Smith??s interpretation Socratic moral psychology becomes rather less distinguishable from its ??Platonic?? counterpart??as that is currently understood??than it is on the interpretation(s) they oppose.  相似文献

This article introduces a simple survey method to distinguish between two types of variables that affect happiness—type A, which exerts an absolute effect on happiness, and type B, which affects happiness only through social context. The authors validate the method by comparing its findings with the findings of a theoretically superior but less practical experimental method, and use the method to identify the AB nature of a variety of naturally-occurring variables among both college students and people with work experience. We conclude by discussing the limitation of this method as well as its potential to inform policymakers about where to invest resources in order to improve people’s happiness over time.  相似文献

The serial reaction time (SRT) task is a simple procedure in which participants produce differentiated responses to each of a series of stimuli presented at varying locations. Learning about stimulus order is revealed through decreased latencies for structured versus randomized sequences. Although widely used with humans and well suited to nonhumans, this paradigm is little used in comparative research. In the present article, we describe an SRT procedure that uses colored circles as stimuli, a circular layout of locations, and symmetrical joystick deflections as responses. In two experiments, we showed that four rhesus macaques (Macaca mulatta) learned to track sequences up to eight items long, with three animals showing faster responding to repeating sequences than to randomized versions. After extended training, these participants also showed evidence of faster responding at all positions within repeating sequences. This method minimizes response effort, equates effort and travel distance across stimulus locations, and is applicable to any joystick-capable species.  相似文献

Parental divorce has been linked to religious outcomes in adulthood. Previous research, however, has not adequately accounted for parental religious characteristics, which may render the association spurious and/or moderate the relationship. Many studies also do not consider subsequent family context, namely, whether one's custodial parent remarries. Using pooled data from three waves of the General Social Survey, we examine the nature of the relationships among parental divorce, subsequent family structure, and religiosity in adulthood. Growing up in a single‐parent family—but not a stepparent family—is positively associated with religious disaffiliation and religious switching and negatively associated with regular religious service attendance. Accounting for parental religious characteristics, however, explains sizable proportions of these relationships. In fact, after accounting for parental religious affiliation and service attendance, growing up with a single parent does not have a significant effect on religious service attendance. Parental religiosity also moderates the relationship between growing up with a single parent and religious service attendance: being raised in a single‐parent home does have a negative effect on religious service attendance among adults who had two religiously involved parents. There is modest evidence of this moderating relationship for other religious outcomes. Implications of these findings are discussed.  相似文献

Comparative rationality analysis formally examines the incommensurable social rationalities that theoretically exist within religions and the social sciences according to the ideological surround model (ISM) of the psychology of religion. This study extended these procedures to a new cultural context: 220 Iranian university students responded to the Religious Problem‐Solving Scales developed by Pargament et al. (1988). As hypothesized, the Collaborative Problem‐Solving Style was consistent, and the Self‐Directing Style inconsistent, with Iranian Muslim religious and psychological adjustment. The Deferring Style had ambiguous implications. Comparative rationality analysis demonstrated that sample interpretations of these styles explained greater variance in adjustment than did the original scales. These procedures also yielded the unexpected discovery that the Deferring Style included a secular as well as a religious form of Iranian rationality. These data most importantly support the ISM claim that “future objectivity” requires empirical analyses of the incommensurable rationalities operating within the psychology of religion.  相似文献

Friend influence over alcohol intoxication and delinquent behavior was examined as a function of relative peer acceptance in a 3-year study of Swedish youth (N = 184 girls, 145 boys). Participants were in the first year of secondary school (7th grade, M = 11.7 years old) or the first year of high school (10th grade, M = 15.3 years old) at the outset. Friends resembled one another before the friendship; resemblances were even greater after the friendship began. Resemblances continued to grow among those who remained friends one year later, but declined among those whose friendships dissolved. Partners were not equally responsible for increases in similarity. In stable friendships, the more accepted partner exerted greater influence over the less accepted partner, such that the greatest increases in problem behaviors were found among less accepted youth whose friends had higher initial levels of delinquency and alcohol intoxication. Unstable friends resembled random pairs of youth in that more- and less-accepted partners were comparably uninfluential.  相似文献

The purpose of this study was to examine variables that affect self-control in the context of academic task completion by elementary school children with autism. In the baseline assessment of Study 1, mathematics problem completion was shown to be an aversive event, and sensitivity to task magnitude, task difficulty, and delay to task completion were measured. The effects of manipulating values of those parameters on self-control then were assessed. For all participants, self-control increased as a function of one or more changes in task parameter values. In Study 2, the effects of a commitment response on self-control was assessed. Results indicated that for all participants, levels of self-control were higher when the opportunity to commit to the immediate aversive event was available.  相似文献

The Internet is a powerful tool that has changed the way people work. However, the ubiquity of the Internet has led to a new workplace threat to productivity-cyberloafing. Building on the ego depletion model of self-regulation, we examine how lost and low-quality sleep influence employee cyberloafing behaviors and how individual differences in conscientiousness moderate these effects. We also demonstrate that the shift to Daylight Saving Time (DST) results in a dramatic increase in cyberloafing behavior at the national level. We first tested the DST-cyberloafing relation through a national quasi-experiment, then directly tested the relation between sleep and cyberloafing in a closely controlled laboratory setting. We discuss the implications of our findings for theory, practice, and future research. (PsycINFO Database Record (c) 2012 APA, all rights reserved).  相似文献
