Prompt Density,Rate of Reinforcement,and the Persistence of Manding

The Psychological Record - Previous research has documented the effects of prompting mands at a relatively high rate (i.e., rich schedule) or low rate (i.e., lean schedule). These previous studies...     

Individual differences in the anterior insula are associated with the likelihood of financially helping versus harming others

The neural basis of individual differences in positive and negative social decisions and behaviors in healthy populations is yet undetermined. Recent work has focused on the potential role of the anterior insula in guiding social and nonsocial decision making, but the specific nature of its activation during such decision making remains unclear. To identify the neural regions mediating individual differences in helpful and harmful decisions and to assess the nature of insula activation during such decisions, in the present study we used a novel fMRI task featuring intentional and unintentional decisions to financially harm or help persons in need. Based on a whole-brain, unbiased approach, our findings indicate that individual differences in dorsal anterior insula, anterior cingulate cortex (ACC), and right temporo-parietal junction activation are associated with behavioral tendencies to financially harm or help another. Furthermore, activity in the dorsal anterior insula and ACC was greatest during unintended outcomes, whether these were gains or losses for a charity or for oneself, supporting models of the role of these regions in salience prediction error signaling. Together, the results suggest that individual differences in risk anticipation, as reflected in the dorsal anterior insula and dorsal ACC, guide social decisions to refrain from harming others.     

Giving Back and Growing in Service: Investigating Spirituality,Religiosity, and Generativity in Young Adults

Generativity investigations have explored the manner by which adults derive meaning and fulfillment from their life activities (e.g., Erikson in Identity, youth, and crisis W.W. Norton & Company Inc.,NY, 1968; McAdams and Logan in American Psychological Association, 15–31, 2004). Faith and religious practice have often been central features of adult meaning making, yet the relationship between one’s spiritual identity and one’s generative concern or activities has received only limited investigation. Lesser still has been investigated examining the degree to which young adults demonstrate generative concern. The current study examined the relationship between aspects of faith (religiosity and spirituality) and generativity (concern and action). A sample of 94 undergraduates from a religiously affiliated college were recruited through door-to-door invitation and were surveyed using a new measure of religiosity (Steger and Frazier in Journal of Counseling Psychology 52(4):574–582, 2005) and two measures of generativity (Loyola Generativity Scale and Generative Behavior Checklist, McAdams et al. 1992). Support was found for a relationship between spirituality and generative concern. These findings are discussed in relation to recent demographic shifts and are compared with earlier work investigating secular spiritual trends on generativity (e.g., Dillon and Wink in The generative society American Psychological Association Press, Washington, DC, 153–174, 2004).     

Psychiatric and behavioral problems in aggressive drivers

Motor vehicle accidents (MVAs) are a leading cause of accidental death and injury, and aggressive driving has been identified as a risk factor for MVAs. Assessing psychiatric and behavioral disturbances in aggressive drivers is germane to the development of prevention and intervention programs for this population. The present study compared the prevalence of psychiatric diagnoses and behavioral problems in young adult drivers with self-reported high driving aggression to that of drivers with low driving aggression. Aggressive drivers evidenced a significantly higher current and lifetime prevalence of Oppositional Defiant Disorder, Alcohol and Substance Use Disorders, and Cluster B Personality Disorders, and a significantly greater lifetime prevalence of Conduct Disorder, Attention-Deficit/Hyperactivity Disorder, and Intermittent Explosive Disorder. Aggressive drivers also had a significantly greater prevalence of self-reported problems with anger, as well as a greater family history of anger problems and conflict. The findings suggest that prevention and intervention programs designed to reduce aggressive driving may need to address the presence of psychiatric and behavioral problems that could potentially complicate treatment or impede responses to treatment.     

One- and two-year prospective follow-up of cognitive behavior therapy or supportive psychotherapy

We followed up over 90% of 57 motor vehicle accident survivors, who completed a controlled comparison of cognitive behavioral therapy (CBT) to supportive psychotherapy (SUPPORT). One-year results showed a continued significant advantage on categorical diagnosis (PTSD or not) and structured interview measures (CAPS) for CBT over SUPPORT. Other measures generally showed the same results. At two years, we were able to follow-up only 75% of one-year completers. Although there continued to be arithmetic differences favoring CBT over SUPPORT, with these attenuated samples only differences on PTSD Checklist and Impact of Event Scale scores and in overall categorical diagnoses were significant. There was very modest improvement from end of treatment to the two-year follow-up.     

Is action naming better preserved (than object naming) in Alzheimer's disease and why should we ask?

The present study compared object and action naming in patients with Alzheimer's dementia. We tested the hypothesis put forward in (some) previous studies that in Alzheimer's dementia the production of verbs, that is required in action naming, is better preserved than the production of nouns, that is required in object naming. The possible reason for the dissociation is that verbs are supported predominantly by frontal brain structures that may remain relatively better preserved in early Alzheimer's disease. Objects, on the other hand, are supported by temporal lobe structures that are affected early in the disease. An alternative hypothesis, which is supported by other studies, is that action naming is more impaired than object naming due to verbs being semantically more complex than nouns. In order to test these contrasting hypotheses, the present study used more stringent methodology than previous studies. We used a larger set of stimuli with carefully matched object and action items and we collected not only accuracy data but also naming latencies, a measure that is sensitive to even mild lexical retrieval problems. We compared the performance of 19 patients with mild to moderate Alzheimer's disease with that of 19 healthy age matched participants. We found that both the patients and the comparison group responded faster and made fewer errors on the object pictures than the action pictures. A qualitative analysis of the naming errors indicated that object and action naming pose different demands for the language system. The results overall suggest that the patients' performance is an exaggeration of the pattern present in the comparison participants.     

Development of the Multidimensional Acculturative Stress Inventory for adults of Mexican origin

The Multidimensional Acculturative Stress Inventory (MASI), a 36-item stress measure that was developed to assess acculturative stress among persons of Mexican origin living in the United States, was tested on a community sample of 174 adults (117 women, 57 men). Principal-components analyses yielded 4 stable and internally consistent factors: Spanish Competency Pressures (7 items), English Competency Pressures (7 items), Pressure to Acculturate (7 items), and Pressure Against Acculturation (4 items). These 4 factors accounted for 64.4% of the variance and correlated in the expected directions with criterion measures of acculturation and/or psychological adjustment. Further reliability and validity testing of the MASI is discussed as well as the utility of this measure in assessing acculturative stress among adults of Mexican origin.     

Toward an assessment of the construct validity of four measures of narcissism

In recent years there has been growing conceptual interest in narcissism, coupled with the rapid development of several paper and pencil measures. Clearly, construct validation should be performed prior to the adoption of any measure. This study reports on the construct validation of four scales that purport to measure narcissism. A conceptual definition of narcissism is provided, and a number of empirical analyses are performed, including examination of internal consistency reliabilities, intercorrelations among the four narcissism scales, and correlations with related and unrelated measures. Three of the four scales were found to be consistently related to each other, and demonstrated similar patterns of substantive and discriminant validity. A factor analysis, performed to examine the structure of the four narcissism measures, suggests four dimensions: desire for attention, admiration, and authority; feelings of inadequacy, unhappiness, and worry; disturbances in interpersonal relationships (exploitation, sense of entitlement, lack of empathy); and sensitivity to criticism and defeat. Implications of the results are discussed.     

The myth of judicial leniency in sentencing

Opinion polls report that the pubic is increasingly critical of perceived judicial leniency in sentencing. To examine the degree and pattern of judicial leniency, Illinois judges and laypersons were asked to impose sentences on the same offenders. Contrary to the myth of judicial leniency, the sentences given by laypersons tended to be equal to or less severe than those given by judges. Explanations are offered for the divergence between myth and reality, including the availability heuristic and the impact of biased recall.
