To treat a psychopath

Some people are now quite optimistic about the possibility of treating psychopathy with drugs that directly modulate brain function. I argue that this optimism is misplaced. Psychopathy is a global disorder in an individual’s worldview, including his social and moral outlook. Because of the unity of this Weltanschauung, it is unlikely to be treatable in a piecemeal fashion. Recent neuroscientific methods do not give us much hope that we can replace, in a wholesale manner, problematic views of the world with more socially desirable ones. There are, therefore, principled reasons that psychopathy is so singularly treatment resistant.     

The Dispositional Flow Scale–2 as a Measure of Autotelic Personality: An Examination of Criterion-Related Validity

The Dispositional Flow Scale–2 (DFS–2; Jackson & Eklund, 2002) may be one of the most promising measures for assessing Csikszentmihalyi's (1990) construct of “autotelic personality.” Despite strong internal validity, external validity of the DFS–2 remains open. We used 2 methods to provide evidence for external validity: (1) multiple-time assessments of experience sampling (1,856 entries generated over 7 days) to derive aggregate indices of criterion validity; and (2) single-time assessments of flow and personality for additional criterion-related validity. For single-time assessments of flow, we used a modified version of the Flow Questionnaire (Csikszentmihalyi & Larson, 1984). To assess personality, we included a measure of the Five-factor traits using the Revised NEO Personality Inventory (Costa & McCrae, 1992). A path model of NEO domains, DFS–2 global scores, and experience sampling aggregates fit the data well.     

Video Intervention for Child and Caregiver Distress Related to the Child Sexual Abuse Medical Examination: A Randomized Controlled Pilot Study

Children who disclose child sexual abuse are often referred for a comprehensive medical exam to ensure physical well-being and gather evidence. This study examined a brief, developmentally appropriate, psychoeducational video designed to instruct children and caregivers about the exam procedures and coping strategies to be used during the exam. Sixty-nine children ages 4–15 and their caregivers were randomly assigned to view the psychoeducational video (n = 35) or to receive standard practice (n = 34). Distress before, during, and after the exam was assessed in both children and caregiver, as were measures of satisfaction and knowledge about the investigation process and coping strategies. Consistent with hypotheses, results indicated that the video intervention was well-received by families, increased caregiver knowledge, and decreased stress during the examination. Caregiver and child distress decreased from pre to post examination across both conditions, and, unexpectedly, there were no significant differences in these decreases between groups. Overall results from this pilot study are promising in supporting a cost-effective and brief early intervention approach at the time of the medical examination for child sexual abuse for children and their caregivers.     

criminal involvement and media use

When researchers investigate the relationships between media behavior and criminal behavior, they tend to focus on the links between the content preferences of offenders and the types of crime they have committed. Offenders, however, also differ with respect to their degree of criminal involvement. Although some authors indicate that the consumption of socially disvalued media contents may have a symbolic value for people with a high degree of criminal involvement, or suggest that media may provide them with useful information, the link between this criminality dimension and media use has seldom been thoroughly studied. This article describes the results of a qualitative and quantitative study into the media use of prisoners in five Flemish penitentiaries. It illustrates that the variable degree of subjective criminal involvement is a particularly strong predictor of media uses, preferences, and interests among confined offenders.     

The Role of Syllable Awareness and Syllable-Controlled Text in the Development of Finger-Point Reading

Concept of word is a pivotal developmental insight that is reflected when preliterate learners are able to repeat a line of print and accurately point to the words while saying them (finger-point reading) and relocate a specific word within that line (word finding). Several studies have shown that letter knowledge, phonemic skills, one-to-one correspondence, and spelling relate to finger-point reading. However, no studies have examined the relationship between syllable awareness and finger-point reading despite the fact that finger-point reading requires learners to handle multisyllabic words. With a group of young children this study examined: (a) the influence of syllable-controlled text on learning finger-point reading and (b) the degree to which syllable awareness would contribute to the prediction of finger-point reading above letter naming and initial sound awareness. Syllable-controlled text did not influence finger-point reading but syllable awareness did predict a significant proportion of the variance in finger-point reading over and above letter knowledge and initial sound awareness. Implications of the interactive nature of phonological and print knowledge are discussed as well as capacity of young children to learn about print.     

Reaction times and electromechanical delay in reactions of increasing and decreasing force

The purpose of this study was to compare reaction times and electromechanical delay between reactions to increase force from rest and reactions to decrease force from an active state in the quadriceps femoris of healthy young adults. Force, position, and electromyographic data were recorded from 35 subjects reacting to a forced knee-flexion perturbation. Electromechanical delay was assessed through cross-correlation of the filtered EMG and force data. Reaction time to increase force (M= 159.9 msec., 95% CI= 149.9-169.9 msec.) was significantly longer than RT to decrease force (M= 124.4 msec., 95% CI= 118.7-130.1 msec.). This difference was partially caused by a difference in electromechanical delay (RT to increase force electromechanical delay was 63 msec., 95% CI=60-67 msec., greater than the RT to decrease force electromechanical delay of 49 msec., 95% CI=46-52 msec.). This difference in reaction time could be important in identifying and interpreting physiologically meaningful changes in muscle force and in intermuscular coordination during movement.     

Children's memory for complex autobiographical events: does spacing of repeated instances matter?

Often, when children testify in court they do so as victims of a repeated offence and must report details of an instance of the offence. One factor that may influence children's ability to succeed in this task concerns the temporal distance between presentations of the repeated event. Indeed, there is a substantial amount of literature on the "spacing effect" that suggests this may be the case. In the current research, we examined the effect of temporal spacing on memory reports for complex autobiographical events. Children participated in one or four play sessions presented at different intervals. Later, children were suggestively questioned, and then participated in a memory test. Superior recall of distributed events (a spacing effect) was found when the delay to test was 1 day (Experiment 1) but there was little evidence for a spacing effect when the delay was 1 week (Experiment 2). Implications for understanding children's recall of repeated autobiographical events are discussed.     

Health-promoting physical activity of adults with mental retardation

This literature review describes the physical activity behavior of adults with mental retardation consistent with the U.S. Surgeon General's recommendation of 30 minutes of moderate intensity physical activity on 5 or more days per week. The proportion of participants achieving this criterion ranges from 17.5 to 33%. These data are likely to be generous estimates of activity as individuals included in physical activity studies to date have been relatively young and healthy volunteers with mild to moderate limitations. Major sources of physical activity were walking and cycling for transport, chores and work, dancing, and Special Olympics. There is a pressing need to conduct studies using appropriately powered representative samples and to validate measures that assess physical activity less directly; including methodologies in which proxy respondents are used. Accurate information about existing patterns of behavior will enhance the development of effective strategies to promote physical activity among persons with mental retardation.
