The Primary and Secondary Factors That Promote Destructive Personalities

The ability of behavioral scientists to assist society deal competently with destructive behavior relies upon a recognition of its causes. Despite the pervasiveness of violence in American society, the roots of destructiveness are still poorly understood. Five primary and five secondary factors found in the developmental histories of people who have become involved in serious destruction are identified and discussed. The confluence of these factors in the steps toward destructive acts are traced.     

Learning Related and Interpersonal Social Skills Constructs in Two Existing Social Skills Assessments

In the social skills literature it has been identified that both learning related social skills and interpersonal social skills may exist. This study ascertained the views of 16 experts regarding the existence of the two proposed constructs, learning related social skills and interpersonal social skills, within two pre-existing assessments: Preschool and Kindergarten Behavior Scales–2nd edition and Child Behavior Rating Scale. Sixteen experts from Australia (n = 11) and Singapore (n = 5) with pediatric backgrounds in occupational therapy, speech pathology, psychology and early childhood education took part in the study. Experts were asked to sort cards with each of the items from the Child Behavior Rating Scale and Preschool and Kindergarten Behavior Scales–2nd edition (66 items in total) into one of two piles (one for learning related social skills and one for interpersonal social skills) and then answered several open ended questions about the clinical utility of these constructs. Preliminary evidence demonstrated the existence of the learning related social skills and interpersonal social skills constructs within the items of the two assessments (Child Behavior Rating Scale and Preschool and Kindergarten Behavior Scales–2nd edition). The experts' opinion also suggested the potential clinical benefits of assessing both learning related social skills and interpersonal social skills in preschool-age children. The study results and implications for further research and clinical practice are discussed.     

The effect of video observation on warmth and competence ratings of individuals with a disability

ObjectivesThis study examined whether a video featuring an adult with a physical disability engaging in either sport, exercise, or an activity of daily living (ADL) can mitigate negative stereotypes of disability held by people without a disability.DesignThis study used a pre-post design, involving three participant groups.MethodsParticipants (n = 212) read a vignette describing an adult with a disability (target). Consistent with the stereotype content model, participants judged the target's warmth and competence. One week later, participants viewed a video of the target participating in sport, exercise, or an ADL and judged the target's warmth and competence.ResultsJudgements of competence but not warmth changed over time. The greatest increases occurred in the sport condition. At follow-up, the typical high warmth low competence stereotype of disability was reversed; the character was judged as being more competent than warm especially in the sport condition.ConclusionVideos of adults with a disability engaging in physical activity, particularly sport, have potential to mitigate negative stereotypes of disability.     

Focusing on Educational Outcomes

National education goals, content standards, and national tests are the hot topics of the day in educational reform. Special services personnel eventually will be faced with these issues, and can either be part of the discussion from the beginning, or wait and have to deal with someone else's decisions. In this article, we highlight some recent national and state educational reform activities and their probable implications for students with disabilities. We explain in brief the impetus behind the thrust toward an outcomesbased approach to education, and summarize the response of the National Center on Educational Outcomes for Students with Disabilities to this push. Possible ways in which special service providers can act to influence the focus on outcomes are described.     

Visuo-Proprioceptive Matching Errors Are Consistent with Biases in Distance Judgments

People make systematic errors when matching the location of an unseen index finger with that of a visual target. These errors are consistent over time, but idiosyncratic and surprisingly task-specific. The errors that are made when moving the unseen index finger to a visual target are not consistent with the errors when moving a visual target to the unseen index finger. To test whether such inconsistencies arise because a large part of the matching errors originate during movement execution, we compared errors in moving the unseen finger to a target with biases in deciding which of two visual targets was closer to the index finger before the movement. We found that the judgment as to which is the closest target was consistent with the matching errors. This means that inconsistencies in visuo-proprioceptive matching errors are not caused by systematic errors in movement execution, but are likely to be related to biases in sensory transformations.     

Is the perceived present a predictive model of the objective present?

ABSTRACT

Processing latencies for coherent, high level percepts in vision are at least 100?ms and possibly as much as 500?ms. Processing latencies are less in other modalities, but still significant. This seems to imply that perception lags behind reality by an amount equal to the processing latency. It has been proposed that the brain can compensate for perceptual processing latencies by using the most recent available information to extrapolate forward, thereby constructing a model of what the world beyond the senses is like now. The present paper reviews several lines of evidence relating to this hypothesis, including the flash-lag effect, motion-induced position shifts, representational momentum, static visual illusions, and motion extrapolation at the retina. There are alternative explanations for most of the results but there are some findings for which no competing explanation has yet been proposed. Collectively, the evidence for extrapolation to the present is suggestive but not yet conclusive. An alternative account of compensation for processing latencies, based on the hypothesis of rapid emergence of percepts, is proposed.     

Effects of cultural themes in psychotic symptoms on the diagnosis of schizophrenia in African Americans

Cultural themes focusing on race-related issues and religiosity were identified via content analysis in the delusions and hallucinations of a sample of 118 African American psychiatric patients. The purpose of the study was to determine whether cultural themes in psychotic symptoms influence the diagnosis from different sources (i.e., chart, SCID, and best estimate) of schizophrenia for Black patients. It was hypothesized that the best estimate diagnoses of cultural experts would diagnose schizophrenia in African Americans more frequently when they exhibit race-related themes in their psychotic symptoms. It was also hypothesized that diagnosis of the paranoid subtype would yield a stronger difference among the sources than the broader category of schizophrenia. The results did not support the hypotheses. Implications for understanding the relationship between culture and psychosis among African Americans are discussed.     

Disjunctivism and the urgency of scepticism

This paper argues that McDowell is right to claim that disjunctivism has anti-sceptical implications. While the disjunctive conception of experience leaves unaffected the Cartesian sceptical challenge, it undermines another type of sceptical challenge. Moreover, the sceptical challenge against which disjunctivism militates has some philosophical urgency in that it threatens the very notion that perceptual experience can acquaint us with the world around us.
