The Implications of Using Group-Based Offenses versus Non-Group-Based Offenses in Peer Deviance Scales

A key distinction from Warr’s research is “groupy” (deviant acts commonly committed with peers) versus “non-groupy” (acts that are likely committed alone) deviance. Drawing on Warr’s important (and underutilized) distinction, this study’s goal is to determine whether measures of perceptual groupy peer deviance more accurately reflect a peer’s true deviance than perceptions of nongroupy peer deviance. Using dyadic data, results demonstrate that perceptions of a peer’s non-groupy deviance are largely inaccurate but perceptions of a peer’s groupy deviance are quite accurate. Despite this discrepancy, groupy and non-groupy perceptual measures function similarly in multivariate models and consistently outperform peer self-reports.     

规范错觉对外出就餐中食物浪费的影响：心理机制与应对策略

规范错觉是指个体的规范感知与实际存在于群体中的社会规范之间存在差异, 规范错觉影响了社会生活的方方面面。对957份问卷调查的分析显示, 人们普遍高估了他人的食物浪费(行为错觉)以及对浪费的赞同程度(态度错觉), 而这两种错觉又加剧了人们自身的浪费行为。中介效应检验显示, 印象管理中的社交性维度部分中介了两种错觉与浪费行为间的关系。两个随机对照实验进一步检验了描述性(命令性)规范信息对行为(态度)错觉的影响, 结果发现, 描述性规范信息降低了行为错觉, 并通过社交性减少了浪费行为; 而命令性规范信息并不改变态度错觉本身, 但通过降低态度错觉对浪费的影响而减少了浪费行为。上述结果意味着两种规范信息尽管高度相似, 但其作用机制却可能不同, 同时这一发现也为政策制定者提出了两种干预途径。     

Does Perceived Peer Delinquency Amplify or Mitigate the Deterrent Effect of Perceived Sanction Risk?

The present article studies the interplay of perceived peer delinquency and perceived sanction risk in crime causation. Different sets of hypotheses are formulated. From Situational Action Theory (SAT), it follows that adolescents who have many delinquent friends are more frequently exposed to a crime-conducive moral context. As a consequence, they will more often feel tempted to engage in criminal behavior, which renders them more responsive to sanction risk. Rational Choice Theory (RCT) suggests that adolescents who have no or few delinquent friends are more responsive to sanction risk because these individuals have more informal costs following from punishment to fear. These hypotheses are tested with longitudinal data from the British PADS+ study. Results provide strong support for the propositions derived from SAT. Perceived peer delinquency conditions the effect of perceived sanction risk, and sanction certainty perceptions are most influential among adolescents with a large number of delinquent friends.     

Observational drawing biases are predicted by biases in perception: Empirical support of the misperception hypothesis of drawing accuracy with respect to two angle illusions

We tested the misperception hypothesis of drawing errors, which states that drawing accuracy is strongly influenced by the perceptual encoding of a to-be-drawn stimulus. We used a highly controlled experimental paradigm in which nonartist participants made perceptual judgements and drawings of angles under identical stimulus exposure conditions. Experiment 1 examined the isosceles/scalene triangle angle illusion; congruent patterns of bias in the perception and drawing tasks were found for 40 and 60° angles, but not for 20 or 80° angles, providing mixed support for the misperception hypothesis. Experiment 2 examined shape constancy effects with respect to reproductions of single acute or obtuse angles; congruent patterns of bias in the perception and drawing tasks were found across a range of angles from 29 to 151°, providing strong support for the misperception hypothesis. In both experiments, perceptual and drawing biases were positively correlated. These results are largely consistent with the misperception hypothesis, suggesting that inaccurate perceptual encoding of angles is an important reason that nonartists err in drawing angles from observation.     

Perceptual precision

The standard view in philosophy of mind is that the way to understand the difference between perception and misperception is in terms of accuracy. On this view, perception is accurate while misperception is inaccurate. However, there is some evidence (albeit controversial evidence) that perceptual experience actually involves widespread inaccuracy. I add to that evidence in the paper. Then I point toward a way of understanding the difference between perception and misperception, not in terms of accuracy alone, but in terms of precision. That is, I argue that perceptual experience is designed to enable more fine-grained discrimination among the properties that are most useful for action, even if that involves inaccuracy. The view in this paper motivates a new account of illusion, on which illusions are imprecise as well as inaccurate. I call this the Precision Account of Illusion.     

Race,Gender, and Perceptions of Peer Delinquency: A Within-Subject Analysis

ABSTRACT

We generated a within-subject analysis that assessed whether changes in delinquency from the same youth were associated with changes in the degree to which the youth perceived the delinquency of their peers across three waves of data. We hypothesized that the effect of within-person changes in perceptions of peer delinquency on changes in delinquency across time should be greatest among young black males. The results revealed that a within-person change in the youths’ perceptions that their peers were engaging in greater delinquency increased offending across time. They also showed that young black males were more likely than young white males and young black and white females to increase their level of delinquency, within-person and across time, when they perceived an increase in their peers’ levels of delinquency. We conclude that scholars may generate deeper theoretical insights and policies that are more efficacious when they reveal the causes of crime that are universal and those that uniquely affect a specific group.     

Item grouping and item randomization in personality measurement

This paper describes a study examining the impact of item order in personality measurement on reliability, measurement equivalence and scale-level correlations. A large sample of university students completed one of three forms of the International Personality Item Pool version of the Big Five personality inventory: items sorted at random, items sorted by factor, and items cycled through factors. Results showed that the underlying measurement model and the internal consistency of the IPIP-Big Five scale was unaffected by differences in item order. Also, most of the scale-level correlations among factors were not significantly different across forms. Implications for the administration of tests and interpretation of test scores are discussed, and future research directions are offered.     

Acculturation, peer relations, and delinquent behavior of Chinese-Canadian youth

Studies have reported that youth of Chinese descent in North America tend to have lower rates of delinquency. Some investigators have attributed this phenomenon to the restraining effects of Chinese culture. In this study, acculturation, peer relations, and delinquency were examined in a sample of Chinese-Canadian youth. The results revealed that adherence to Chinese culture was related to lower delinquency, whereas the opposite was true for North American acculturation. It was found that association with delinquent peers was positively related and attachment to peers negatively related to delinquency, as predicted by differential association and control theories, respectively. Moreover, acculturation was positively related to association with delinquent peers and attachment to peers. However, there was the unexpected finding that association with Chinese peers was positively related to delinquency. These seemingly contradictory findings demonstrate the dilemma experienced by Chinese youth in North America.     

Delinquent Peer Influence on Childhood Delinquency: The Moderating Effect of Impulsivity

A link between delinquent peer affiliations and childhood delinquency has been consistently found in the literature. However, little to no research has examined how the characteristics of an individual may impact this association. Impulsivity may be an important individual characteristic to consider, as impulsivity is associated with childhood delinquency. Accordingly, the current study examined the potential moderating effect of impulsivity on the association between peer delinquency and child delinquency in a community sample of 89 children ranging from 9 to 12 years of age (mean = 10.4 ± 1.1 yrs). Findings suggest that at low levels of impulsivity peer delinquency and child delinquency were positively associated; however at high levels of impulsivity peer delinquency and child delinquency were not statistically related. These findings may suggest that children who exhibit low levels of impulsivity are particularly vulnerable to delinquent peer influences. Implications for findings are discussed.     

The relationship of adolescent peer groups to the incidence of psychosocial problems

This study combined a treatment sample (n = 127) and a control sample (n = 114) of adolescents (ages 13-17) to investigate the relationship between adolescent peer groups and incidence of psychosocial problems. A content analysis resulted in four separate types of peer groups. The group with the lowest level of involvement in school activities was labeled by other adolescents in negative terms. An analysis of variance indicated that the least involved and most negatively labeled group generally had the most positive attitudes toward alcohol and drug use, the lowest levels of perceived harm due to alcohol and drug use, and the highest levels of alcohol abuse, drug use, delinquency, and depression. This group also had the lowest level of self-esteem, most external locus of control, least perceived access to occupational opportunities, and highest level of societal estrangement. The results are interpreted as providing support for both control and labeling theories. Implications for theory-based intervention are discussed.     

applying social learning theory to police misconduct

Although numerous studies have attempted to understand the causes of various forms of police misconduct, there is still no clear theoretical explanation of police misbehavior. Akers’ social learning theory posits that peer associations, attitudes, reinforcement, and modeling are predictors of delinquency and crime in general. With this article, we seek to determine if the theory can account for police deviance. Data from a random sample of Philadelphia police officers are used to examine how officer attitudes and perceptions of peer behavior are related to citizen complaints of police misconduct. Findings suggest that social learning theory provides a useful explanation of police misconduct.     

Misperceptions in intergroup conflict. Disagreeing about what we disagree about

Two studies examined misperceptions of disagreement in partisan social conflicts, namely, in the debates over abortion (Study 1) and politics (Study 2). We observed that partisans tend to exaggerate differences of opinion with their adversaries. Further, we found that perceptions of disagreement were more pronounced for values that were central to the perceiver's own ideology than for values that were central to the ideology of the perceiver's adversaries. To the extent that partisans assumed disagreement concerning personally important values, they were also inaccurate in perceiving their adversaries' actual opinions. Discussion focuses on the cognitive mechanisms underlying misperceptions of disagreement and strategies for reducing intergroup conflict.     

The effects of perceived social norms on handwashing behaviour in students

Handwashing is widely considered the most effective method of preventing the spread of infectious illness. Exploring the determinants of handwashing is vital to the development of interventions to increase this behaviour. A survey based on Social Norms Theory assessed handwashing frequency and perceptions of peer handwashing in 255 university students. Participants reported their own handwashing frequency, and how often they thought their peers washed their hands in particular circumstances, to determine whether misperceptions around handwashing exist, and whether these influence the behaviour of individuals. Gender was found to be a significant determinant of handwashing frequency as females reported washing their hands significantly more often than males. Participants also believed they washed their hands significantly more frequently than their peers. Perceived peer handwashing frequency was significantly correlated with participants’ own behaviour. This effect was seen in overall handwashing and in food, waste and illness-related hand washing. These results suggest perceived social norms around hand washing have a clear association with individual behaviour. Future research might test the effectiveness of a social norms intervention in other settings which carry an increased risk of infection spread.     

MMPI Factor Analytic Findings for Adolescents: Item- and Scale-Level Factor Structures

Although numerous studies have examined the factor structures of the Minnesota Multiphasic Personality Inventory (MMPI) in investigations of adults, very little attention has been directed to this issue in adolescent samples. In this study, we investigated the item-level and scale-level factor structures using a sample of 1,762 adolescents receiving psychiatric services at the time of their MMPI assessment. Results identified 17 factors related to item responses and 5 factors based on scale-level data. Findings are discussed in relation to results obtained in adult populations and the potential utility of factor analytically derived content scales for adolescent MMPI interpretation.     

Acculturative dissonance, ethnic identity, and youth violence

Studies suggest that the process of acculturation for immigrant youth, particularly for second-generation youth, is significantly associated with delinquency and violence. This study explored the acculturation-violence link with respect to acculturative dissonance and ethnic identity. The results revealed in a sample of 329 Chinese, Cambodian, Mien/Laotian, and Vietnamese youth that acculturative dissonance was significantly predictive of serious violence, with full mediation through peer delinquency. Ethnic identity was not significantly associated with peer delinquency or serious violence. Although acculturative dissonance and ethnic identity accounted for a small percentage of variance in violence compared with peer delinquency, it cannot be discounted as trivial. Structural equation analyses provided support for both measurement and structural invariance across the four ethnic groups, lending support for cross-cultural comparisons. The results also lend support for the inclusion of cultural factors in youth violence prevention and intervention efforts.     

Methodological and empirical developments for the Ratcliff diffusion model of response times and accuracy

Summerfield, Egner, Mangels, and Hirsch (2006) suggested that visual misperception may be triggered by strong yet wrong expectation when sensory data are insufficient. Bar (2003) posits that immediately after stimulus presentation, low frequency spatial information (LFSI) convey the global form of the image which is matched to stored representations in the orbitofrontal cortex to generate predictions of the input. We used signal detection to test whether a strong prediction induced by informative global form, hence reducing the number of possible input matches, would facilitate recognition, but at the price of increasing the rate of misperceptions. Twenty-five participants were presented with target and foil images that shared global form, but differed in details. Pictures with informative global form resulted in higher confidence in recognition and shorter reaction times, but increased false alarms. Predictions of sensory input based on low frequency spatial information allow quick, facilitated recognition. However, the price for speed is the increased rate of misperceptions.     

Reexamining the link between parental knowledge and delinquency: unpacking the influence of adolescents’ and their parents’ perceptions

ABSTRACT

Parents’ and their children’s perceptions of how much parents know about the child’s activities outside parental presence (parental knowledge) are important for understanding delinquency. Yet, conceptual and methodological deficiencies in prior research may limit this understanding. Reexamining how these perceptions affect delinquency, we find that contrary to conventional wisdom: (1) adolescent and parent perceptions of parental knowledge impact delinquency jointly rather than independently and (2) the protective effect of adolescent perceptions weakens as parent perceptions increase. Specifically, when parental perceptions are strongest, the delinquency inhibiting effect of adolescent perceptions is offset, which may result from stress of parents’ monitoring efforts.     

Effect of Political Positioning on Explanations of Delinquency: An Experimental Study of Social Differentiation and Representation

Why and under what conditions do subjects from diverse political orientations tend to offer different explanations of a social problem? Past studies have found evidence of a connection between political orientations and explanations of delinquency, for example. However, observing such differences among subjects with diverse political orientations is not enough to prove the existence of an organic link between social differentiation and the representations of delinquency. The aim of this paper is to provide an experimental proof of such a link. The results show that: (a) right‐wing and left‐wing subjects tend to offer different types of explanations of delinquency, but they refer to several common organizing principles; (b) divergence increases when social comparison between groups is activated; (c) differences are bigger if this comparison induces a discrimination; (d) the bigger the differences the more likely are the groups to resort to their ideological principles. Results are discussed in terms of theoretical, methodological, deontological, and practical implications.

The logic of misperceived distance (or location) theories of the Poggendorff illusion

For the Poggendorff display (transversal interrupted by parallel lines), the typical distance-misperception theory postulates that a particular linear distance extending across the empty space between parallels is underestimated; examples are the intertransversal slant distance defined by the closest ends of the transversal segments (a “wings-in Müller-Lyer like” underestimation) or the perpendicular distance between parallels (parallels “attract”). Distance misperception by itself, however, can neither establish that perceived transversal misalignment exists for a Poggendorff display nor specify the perceivedlocation conditions) that will produce perceptual collinearity. The perceptual displacement vector is introduced as a means of specifying fully the perceptual mislocation (displacement) of one transversal segment with respect to the other. Given this vector information (direction as well as distance), the logical soundness of theories postulating distance or location misperception were evaluated, and they were compared on the basis of extant data. Such vector information can be used to evaluate other classes of theories as well.
