Observation procedure, observer gender, and behavior valence as determinants of sampling error in a behavior assessment analogue

Several factors thought to influence the representativeness of behavioral assessment data were examined in an analogue study using a multifactorial design. Systematic and unsystematic methods of observing group behavior were investigated using 18 male and 18 female observers. Additionally, valence properties of the observed behaviors were inspected. Observers' assessments of a videotape were compared to a criterion code that defined the population of behaviors. Results indicated that systematic observation procedures were more accurate than unsystematic procedures, though this factor interacted with gender of observer and valence of behavior. Additionally, males tended to sample more representatively than females. A third finding indicated that the negatively valenced behavior was overestimated, whereas the neutral and positively valenced behaviors were accurately assessed.     

Mind Perception and Individual Differences: A Replication and Extension

Mind perception involves attributing higher functional abilities to others (e.g., saying a dog feels pain). The relationships between mind perception and psychopathology—autism, psychopathy, and schizotypy—have been revealed by K. Gray, Jenkins, Heberlein, and Wegner (2011 Gray, K., Jenkins, A. C., Heberlein, A. S., &; Wegner, D. M. (2011). Distortions of mind perception in psychopathology. Proceedings of the National Academy of Sciences of the United States of America, 108, 477–479. doi:10.1073/pnas.1015493108[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]); however, mind perception has yet to be correlated with personality. Participants (N = 180) completed measures of personality, psychopathology, and mind perception. The psychopathology results were consistent with Gray et al. (2011 Gray, K., Jenkins, A. C., Heberlein, A. S., &; Wegner, D. M. (2011). Distortions of mind perception in psychopathology. Proceedings of the National Academy of Sciences of the United States of America, 108, 477–479. doi:10.1073/pnas.1015493108[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). The Big Five captured mind perception virtually as much as the three psychopathologies captured mind perception. Mind perception is not solely relevant to psychopathology; it is also relevant to everyday personality.     

Suicidality in Bipolar Disorder: The Role of Emotion‐Triggered Impulsivity

A growing body of research suggests that impulsive responses to emotion more robustly predict suicidality than do other forms of impulsivity. This issue has not yet been examined within bipolar disorder, however. Participants diagnosed with bipolar I disorder (n = 133) and control participants (n = 110) diagnosed with no mood or psychotic disorder completed self‐report measures of emotion‐triggered impulsivity (Negative and Positive Urgency Scales) and interviews concerning lifetime suicidality. Analyses examined the effects of emotion‐triggered impulsivity alone and in combination with gender, age of onset, depression severity, comorbid anxiety, comorbid substance use, and medication. A history of suicide ideation and attempts, as well as self‐harm, were significantly more common in the bipolar disorder group compared with the control group. Impulsive responses to positive emotions related to suicide ideation, attempts, and self‐harm within the bipolar group. Findings extend research on the importance of emotion‐triggered impulsivity to a broad range of key outcomes within bipolar disorder. The discussion focuses on limitations and potential clinical implications.     

Personality,self-efficacy and risk-taking in parkour (free-running)

ObjectiveTo assess the effect of self-efficacy on the relationship between personality and risk-taking in parkour/free-running, a growing high-risk sport.DesignQuantitative cross-sectional study.Method277 parkour and free-running practitioners were recruited online to complete a survey assessing Big Five personality traits, self-efficacy and perceived risk-taking.ResultsGreater reckless risk-taking behaviours were associated with high neuroticism (p = .013) and low conscientiousness (p = .004). Mediation analysis showed that self-efficacy exerted a significant (95% CI) indirect mediation on the relationship between personality traits of neuroticism and conscientiousness, and risk-taking. Extraversion did not predict risk-taking, and was not significantly mediated by self-efficacy.ConclusionsSelf-efficacy plays a significant mediation role in the relationship between stable traits of neuroticism and conscientiousness, and risk-taking amongst parkour/free-running practitioners. This may help elucidate reasons underlying risky sports behaviours.     

Epileptic encephalopathies and their relationship to developmental disorders: do spikes cause autism?

Epileptic encephalopathies are progressive clinical and electroencephalographic syndromes where deterioration is thought to be caused by frequent seizures and abundant EEG epileptiform activity. Seizures occur in approximately 10-15% of children with pervasive developmental disorders (PDD) and 8-10% have epileptiform EEG abnormalities without seizures. Thirty percent of children with PDD have regression of social behavior and language at 2-3 years of age. Some authors speculate that the regression is caused by epileptiform activity even in the absence of overt clinical seizures ("autism with epileptic regression") and suggest that elimination of the epileptiform activity, either medically or surgically, should lead to improvement in behavior. This review examines the data showing that interictal epileptiform discharges are associated with transient clinical dysfunction and discusses the implications of these observations for autistic behavioral abnormalities. The results of resective surgery, vagal nerve stimulation, and multiple subpial transaction on children with autism and epileptiform EEG abnormalities are also discussed. I conclude that there is no evidence that interictal discharges per se cause (or contribute to) the complex behavioral phenotype of autism. There is no justification to support the use of anticonvulsant medication or surgery in children with PDD without seizures; that is, there is no evidence that treatment to eliminate EEG spikes will have a therapeutic effect on the behavioral abnormalities of PDD and autism.     

Activity settings as the unit of analysis: A theoretical basis for community intervention and development

Theory, methods, and action develop within context, one of which is the intellectual climate of an era. Community psychology is directly and indirectly interactive with many intellectual currents, such as postmodernism, semiotics, hermeneutics, and dialogism. These ideas are discussed as they impact on community psychology, with an emphasis on the reemergence of meaning as a central condition of psychology and community. Meaning is of key importance to the unifying concept in the transactional theoretical model which is presented. How this model might serve as a conceptual framework for an asset approach to community intervention and development is discussed. Increasingly, it is recognized that the development of theory to guide community research and action is necessary to advance intervention and to realize the potential of community psychology. It is argued that community psychology is positioned by concepts and practice squarely at the point of emerging thought, and can make fuondational contributions to general social science. The next article in this special section illustrates concepts of this model in an early education program and the remaining article illustrates the influence of ecocultural factors.
