Further evidence that object-based correspondence effects are primarily modulated by object location not by grasping affordance

Tipper, Paul and Hayes found object-based correspondence effects for door-handle stimuli for shape judgments but not colour. They reasoned that a grasping affordance is activated when judging dimensions related to a grasping action (shape), but not for other dimensions (colour). Cho and Proctor, however, found the effect with respect to handle position when the bases of the door handles were centred (so handles were positioned left or right; the base-centred condition) but not when the handles were centred (the object-centred condition), suggesting that the effect is driven by object location, not grasping affordance. We conducted an independent replication of Cho and Proctor's design, but with behavioural and event-related potential measures. Participants made shape judgments in Experiment 1 and colour judgments in Experiment 2 on the same door-handle objects. Correspondence effects on response time and errors were obtained in both experiments for the base-centred condition but not the object-centred condition. Effects were absent in the P1 and N1 data, which are consistent with the hypothesis of little binding between visual processing of grasping component and action. These findings question the grasping-affordance view but support a spatial-coding view, suggesting that correspondence effects are modulated primarily by object location.     

Make the manikin move: Symbolic approach–avoidance responses affect implicit and explicit face evaluations

The present research aimed to replicate and extend findings of Huijding, Muris, Lester, Field, and Joosse (2011), investigating whether symbolic approach–avoidance responses can induce implicit and explicit evaluation biases. Faces with a neutral expression were shown on a computer screen, and participants were instructed to repeatedly move a manikin towards some faces (approach) and away from other faces (avoidance). An affective priming task and a face rating task were used to assess training-compatible differences in implicit and explicit face evaluations, respectively. Results showed that the manikin training was successful: The priming task revealed more positive implicit evaluations of approached than avoided faces, and approached faces were rated more positively than avoided ones in the face rating task. These findings replicate those of Huijding and colleagues by demonstrating training effects on explicit evaluations, and they extend them by demonstrating effects on implicit evaluations.     

Preferring alphabet–keyboard compatibility: Congruency between spatial codes shapes the affective connotation of letters

When letters are encountered, two spatial stimulus codes resulting from their positions within the alphabet and on the computer keyboard are activated mentally. If these two spatial codes match, letter processing is more efficient. The present study tested whether the processing fluency gain resulting from alphabet–keyboard compatibility also enhances affective evaluations of letters. In Experiment 1, participants preferred alphabet–keyboard compatible over incompatible letters in a forced-choice preference rating. Similarly, in Experiment 2, liking ratings for alphabet–keyboard compatible letters were higher compared to incompatible letters. Moreover, in Experiment 3, preference ratings of non-words were positively correlated with the relative number of alphabet–keyboard compatible letters within these letter strings. These findings suggest that alphabet–keyboard compatibility shapes the affective connotation of letters. Moreover, this processing fluency–valence association is activated at the level of letters as well as whole letter strings.     

School shooting fatalities and school corporal punishment: A look at the states

Student deaths from school shootings were examined across all 50 states according to the state’s policy on the use of corporal punishment in schools after controlling for associated differences in poverty rates and the prevalence of conservative Christian religions. There were significantly more school shooting deaths found in states allowing school corporal punishment compared with those that do not. The odds of fatal involvement in a school shooting were greatest in states permitting school corporal punishment compared with those prohibiting it (odds ratio, 2.04) or restricting it to districts serving less than half the student population (odds ratio, 1.77). Moreover, the rate of school corporal punishment was moderately correlated with the rate of fatal school shootings both across all states and within the South, the region in which endorsement of school corporal punishment is most prevalent.Aggr.

Gender,the Perception of Aggression,and the Overestimation of Gender Bias

The purpose of this study was to investigate how the gender of aggressor, target, and observer influences the perception and evaluation of aggression. One hundred seventy-one university students (predominantly White) read 1 of 8 vignettes that described an aggressive act. The aggressor–target gender combinations and the aggressive act were varied. Data did not support the hypothesis that, because of the impact of gender stereotypes, participants would perceive more aggressiveness in men's aggression than in women's aggression. Participants rated women's aggression as more acceptable than men's aggression, and male participants considered the aggression more acceptable, apparently because they saw the act as less aggressive. In addition, participants estimated how most men/women would perceive and evaluate the aggression. Results suggest that people overestimate how biased others are toward members of their own gender.     

Evaluation of the Responding in Peaceful and Positive Ways (RIPP) Seventh Grade Violence Prevention Curriculum

We evaluated the impact of RIPP-7, a seventh grade violence prevention curriculum designed to strengthen and extend the effects of the sixth grade RIPP-6 curriculum. Classes of seventh graders at two urban middle schools serving predominantly African-American youth where RIPP-6 had been implemented the preceding school year were randomized to intervention (N = 239) and control groups (N = 237). Compared to students in the control group, students who participated in RIPP-7 had fewer disciplinary code violations for violent offenses during the following school year. A limited number of main effects were found on self-report outcome measures and measures of attitudes. Although significant main effects were not found on self-report measures of physical aggression, drug use, or anxiety, analyses of interactions with pretest scores indicated that intervention effects were significantly moderated by pretest scores for several outcome measures. Students most likely to benefit from the intervention were those who reported higher pretest rates of problem behaviors including violent behavior, nonphysical aggression, and delinquent behavior.     

How Do I Treat My Hungry Lion: A Model for Violence Management in Prison

This theoretical model for the management of violence relies on the notion that there are fundamentally only two kinds of prison violence—provoked and unprovoked—and that all violence is caused by the influence of some fear-causing agent which triggers the autonomic nervous system's Fight or Flight Response (FFR) which in turn causes the release of FFR chemicals to create and enable an action potential for violence in the actor. Provoked violence is an act of violence which occurs in response to an FFR instigated by some external, independent contemporaneous, real or imagined fear causing agent. Treating provoked violence must include suppressing the production of an excess of FFR stimulant chemicals, which at the same time employing psychodynamic therapy to modify the negative behavior learned from a lifetime of excessive responses to FFR chemical releases. Unprovoked violence is the result of an actor's addiction to FFR chemicals. This addiction leads the actor to experience an apperceptive compulsion to engage in thrill seeking as a method of exposing himself to fear causing agents that are calculated to cause the release of FFR chemicals. In order to treat unprovoked violence you must treat both the chemical addiction and the negative pattern of behavior which was learned to support the habit of self-triggering an FFR. Thus any successful treatment of violence must employ both energetic and psychodynamic models for development of fear management strategies.     

Preventing School Violence by Promoting Wellness

This paper presents a framework for school-based health promotion and prevention programming that can serve to guide planning and action. Rather than separating specific prevention programs (such as violence prevention, substance abuse prevention, etc.) from more broad-based youth development efforts, this approach provides an integrated framework that: (a) identifies benchmarks of healthy development and strategies to support this development across contexts; (b) specifies additional factors that contribute to identified problems that are not directly linked to healthy development; and (c) provides for matching services to individual needs. Suggestions for application of this framework are discussed, with a particular focus on its application to the development of school-based Wellness Centers.     

Teasing,rejection, and violence: Case studies of the school shootings

Media commentators have suggested that recent school shootings were precipitated by social rejection, but no empirical research has examined this claim. Case studies were conducted of 15 school shootings between 1995 and 2001 to examine the possible role of social rejection in school violence. Acute or chronic rejection—in the form of ostracism, bullying, and/or romantic rejection—was present in all but two of the incidents. In addition, the shooters tended to be characterized by one or more of three other risk factors—an interest in firearms or bombs, a fascination with death or Satanism, or psychological problems involving depression, impulse control, or sadistic tendencies. Implications for understanding and preventing school violence are discussed. Aggr. Behav. 29:202–214, 2003. © 2003 Wiley‐Liss, Inc.
