Visual causal impressions in the perception of several moving objects

Several kinds of visual causal impressions occur when people observe stimuli involving objects in motion. It is hypothesized that these impressions occur when the visual system avoids coincidences by matching the observable kinematic features of the stimulus to a template of a physical mechanism. This was tested by constructing a stimulus in which several spatially separated objects move in a coordinated manner. Variations on this stimulus were constructed such that some were inconsistent with a possible physical mechanism that could explain the motions of the objects and others were consistent with it. Mechanism‐inconsistent variations yielded significantly lower ratings of the causal impression and mechanism‐consistent variations did not, supporting the hypothesis. Misperceptions of features of the stimulus were also reported by a majority of participants, and the nature of these misperceptions is also consistent with the hypothesis that the stimulus is interpreted as a representation of a kind of physical mechanism.     

Perceived causality and perceived force: Same or different?

Visually perceived interactions between objects, such as animated versions of billiard ball collisions, give rise to causal impressions, impressions that one object produces some effect in another, and force impressions, impressions that one object exerts a certain amount of force on another. In four experiments, evidence for strong divergence between these two impressions is reported. Manipulations of relative direction of motion and point of contact between the objects had different effects on the causal and force impressions (Experiment 1); delay between one object contacting another and the latter starting to move had a stronger effect on the causal impression than on the force impression (Experiment 2); a context of other moving objects significantly weakened the causal impression but not the force impression (Experiment 3); and there was an inverse relation between an impression of one object penetrating another and the amount of force the former was perceived as exerting on the latter (Experiment 4). These findings are explained in terms of differential effects of instructions on attention, and also in terms of differences in meaning between force and causality.     

Youth gang affiliation,violence, and criminal activities: A review of motivational,risk, and protective factors

Youth gangs are a universal phenomenon attracting increasing attention; the criminal and antisocial behavior perpetuated by youth gangs has an adverse impact on local communities across the globe. Although there is an extensive body of research that has examined the problems posed by youth gangs in America (and more recently in other countries), there have been relatively fewer empirical studies that examined the factors and psychological processes that are related to youth joining and leaving gangs. This review compiles the international research on the nature of youth gangs and critically evaluates: (a) the factors that motivate engagement in and desistance from gang-related activities, (b) risk and protective factors that impact on youths' propensity for gang membership, delinquency, and violent behavior, and the adverse consequences associated with gang affiliation, and (c) the relationship between gang-affiliation, youth violence, and criminal behavior.     

Paranoid thinking in mass shooters

Mass murderers, particularly school shooters, are depicted in the literature as either reacting with rage to taunts and bullying or as being psychopathic. However, examination of diaries and Web sites left by a subset of mass shooters (e.g., Eric Harris, Kimveer Gil, Seung-Hui Cho, Anders Breivik) reveals a different phenomenology than that typically proposed. This group greatly exaggerates the negativity of their treatment as reported by third-party school peers. They become and remain fixated and obsessed with rejection by what they see as an elite in-group whom they see as having unfairly achieved success. Instead of transcending the rejection, they formulate plans to annihilate the transgressors, which they justify as vengeance for the transgressions made against them. The self-exacerbating and obsessive qualities of these perceptions are more consistent with paranoid thinking than with psychopathy. The perceptions feed on themselves and, being part of a closed belief system, expand with time. In the rare cases where the perpetrator survives the mass shooting, they are diagnosed as paranoid schizophrenic. We focus on the pre-psychotic deterioration of their thinking.     

Commentary: Using Potential Outcomes to Understand Causal Mediation Analysis

In this commentary, we demonstrate how the potential outcomes framework can help understand the key identification assumptions underlying causal mediation analysis. We show that this framework can lead to the development of alternative research design and statistical analysis strategies applicable to the longitudinal data settings considered by Maxwell, Cole, and Mitchell (2011).     

Vitalistic thinking in adults

Vitalistic thinking has traditionally been associated with reasoning about biological phenomena. The current research aimed to investigate a broader range of vitalistic thinking than previously studied. Esoteric notions of ‘energy’ are frequently used by individuals when making causal attributions for strange occurrences, and previous literature has linked such thinking with paranormal, magical, and superstitious beliefs. Two experiments are described that aim to investigate whether adults are vitalistic when asked to make causal judgments, and whether this can be predicted by thinking styles and prior paranormal belief. Experiment 1 asked participants to rate three causal options (one of which was vitalistic) for six vignettes. Scores on one dimension of paranormal belief (New Age Philosophy) and analytical thinking significantly predicted vitalism, but scores on intuitive thinking and Traditional Paranormal Beliefs did not. Experiment 2 extended the findings by asking participants to generate their own causal responses. Again, paranormal belief was found to be the best predictor of vitalism, but this time Traditional Paranormal Beliefs were associated with vitalistic responses whilst both intuitive and analytical thinking were unable to significantly predict classification. Results challenge previous findings, suggesting that vitalistic thinking may operate differently when applied to everyday causal reasoning.     

From cleaning up to helping out: Parental socialization and children's early prosocial behavior

Relations between parental socialization and infants’ prosocial behavior were investigated in sixty three 18- and 30-month old children. Parents’ socialization techniques (e.g., directives, negotiation, reasoning) differed for the two age groups, as did relations between socialization and different forms of emerging prosocial behavior (helping; sharing).     

Animal Cruelty,Domestic Violence,and Social Disorganization in a Suburban Setting

ABSTRACT

Breaking away from a focus on the influence of individual characteristics on animal cruelty and guided by social disorganization theory, we investigated animal cruelty violations in block groups in a city in coastal Virginia. We discovered that block groups with higher levels of social disorganization, measured by economic disadvantage, ethnic heterogeneity, residential mobility, and family disruption, had higher levels of animal cruelty violations and reports of aggravated and simple domestic violence. The rates of animal cruelty violations were significantly correlated with aggravated domestic violence but not reports of simple domestic violence.     

Assessment of Time Management Skills (ATMS): A Practice-Based Outcome Questionnaire

This study assessed test–retest reliability and internal consistency of the Assessment of Time Management Skills (ATMS), a self-report questionnaire designed to assess awareness and use time management strategies to plan and manage daily life tasks. Participants included 18 to 65 year-old people (N = 241) from the general population. The questionnaire's content validity was established. The tool demonstrated good internal consistency (α = 0.86). Test–retest reliability for the score revealed a Pearson Coefficient of Correlation (PCC) r = 0.89. The ATMS may be a useful tool for evaluating the effectiveness of rehabilitation designed to improve time management skills.
