Effects of reducing attentional demands on performance of reading comprehension tests by third graders

The researchers examined the effects of reducing attentional demands on reading comprehension test scores. Third grade students (N=939) completed two forms (T & S) of the Stanford 9 Reading Comprehension Test (54 items, 50 min.) in the spring of 1999. Form T (state-mandated) was administered following standardized procedures in one session. Form S (alternate) was administered in multiple, divided-time sessions, that is, the total test time and items were divided in halves and thirds per session to lessen attentional demands. A repeated-measure analysis of variance yielded significant effects for average and low readers. A resource match explanation and a metacognitive explanation are offered for the results, and educational implications are discussed.     

The effects of state and trait self-focused attention on sexual arousal in sexually functional and dysfunctional women

This study examined the effects of state self-focused attention on sexual arousal and trait self-consciousness on sexual arousal and function in sexually functional (n=16) and dysfunctional (n=16) women. Self-focused attention was induced using a 50% reflectant television screen in one of two counterbalanced sessions during which self-report and physiological sexual responses to erotic films were measured. Self-focused attention significantly decreased vaginal pulse amplitude (VPA) responses among sexually functional but not dysfunctional women, and substantially decreased correlations between self-report and VPA measures of sexual arousal. Self-focused attention did not significantly impact subjective sexual arousal in sexually functional or dysfunctional women. Trait private self-consciousness was positively related to sexual desire, orgasm, compatibility, contentment and sexual satisfaction. Public self-consciousness was correlated with sexual pain. The findings are discussed in terms of Masters and Johnson's [Masters, W. H. & Johnson, V. E. (1970). Human sexual inadequacy. Boston: Little, Brown) concepts of "spectatoring" and "sensate focus."     

Electrophysiological analysis of error monitoring in schizophrenia

In this study, the authors sought to determine whether abnormalities exhibited by schizophrenia patients in event-related potentials associated with self-monitoring--the error-related negativity (ERN) and the correct response negativity (CRN)--persist under conditions that maximize ERN amplitude and to examine relationships between the ERN and behavior in schizophrenia. Participants performed a flanker task under 2 contingencies: one encouraging accuracy and another emphasizing speed. Compared with healthy participants, in schizophrenia patients the ERN was reduced in the accuracy condition, and the CRN was enhanced in the speed condition. The amplitude of a later ERP component, the error positivity, did not differ between groups in either task condition. Reduced self-correction and increased accuracy following errors were associated with larger ERNs in both groups. Thus, ERN generation appears to be abnormal in schizophrenia patients even under conditions demonstrated to maximize ERN amplitude; however, functional characteristics of the ERN appear to be intact.     

Child pornography offenses are a valid diagnostic indicator of pedophilia

This study investigated whether being charged with a child pornography offense is a valid diagnostic indicator of pedophilia, as represented by an index of phallometrically assessed sexual arousal to children. The sample of 685 male patients was referred between 1995 and 2004 for a sexological assessment of their sexual interests and behavior. As a group, child pornography offenders showed greater sexual arousal to children than to adults and differed from groups of sex offenders against children, sex offenders against adults, and general sexology patients. The results suggest child pornography offending is a stronger diagnostic indicator of pedophilia than is sexually offending against child victims. Theoretical and clinical implications are discussed.     

Psychological collectivism: a measurement validation and linkage to group member performance

The 3 studies presented here introduce a new measure of the individual-difference form of collectivism. Psychological collectivism is conceptualized as a multidimensional construct with the following 5 facets: preference for in-groups, reliance on in-groups, concern for in-groups, acceptance of in-group norms, and prioritization of in-group goals. Study 1 developed and tested the new measure in a sample of consultants. Study 2 cross-validated the measure using an alumni sample of a Southeastern university, assessing its convergent validity with other collectivism measures. Study 3 linked scores on the measure to 4 dimensions of group member performance (task performance, citizenship behavior, counterproductive behavior, and withdrawal behavior) in a computer software firm and assessed discriminant validity using the Big Five. The results of the studies support the construct validity of the measure and illustrate the potential value of collectivism as a predictor of group member performance.     

The psychophsiology of aggressive drivers: comparison to non-aggressive drivers and pre- to post-treatment change following a cognitive-behavioural treatment

Twenty drivers were remanded to our treatment program by the courts following arrests related to serious aggressive driving behaviors. Ten additional drivers entered our program in response to our advertisements thus identifying themselves as aggressive drivers. Psychophysiological assessments were conducted on all 30 drivers and heart rate (HR), systolic and diastolic blood pressure (SBP and DBP), and skin resistance level (SRL) were measured in response to exposure to a mental arithmetic neutral stressor, two idiosyncratic, audio-taped, aggressive driving vignettes (audio 1 and audio 2), and one non-driving related fearful vignette. Fourteen non-aggressive driving controls also completed the assessment. The results indicated that the aggressive drivers (ADs) showed significantly more SBP responsivity during audio 1 and audio 2 and significantly less SBP reactivity during the mental arithmetic stressor than the controls. The aggressive drivers then completed a four-week, group intervention which included relaxation techniques specifically targeting aggressive driving behaviors. The same psychophysiological assessment was conducted at post-treatment. The results showed significant pre- to post-treatment decreases in HR, p<0.003, SBP, p<0.01, and DBP, p<0.02 during audio 1. Similarly, decreases were evident in audio 2 in SBP, p<0.03 only. No decreases in reactivity occurred during the neutral stressor or fearful situation.     

Les passions de l'ame: on obsessive and harmonious passion

Passion is defined as a strong inclination toward an activity that people like, that they find important, and in which they invest time and energy. Two types of passion are proposed: obsessive and harmonious. Obsessive passion (OP) refers to a controlled internalization of an activity in one's identity that creates an internal pressure to engage in the activity that the person likes. Harmonious passion (HP) refers to an autonomous internalization that leads individuals to choose to engage in the activity that they like. HP promotes healthy adaptation whereas OP thwarts it by causing negative affect and rigid persistence. Results from four studies involving more than 900 participants from different populations supported the proposed conceptualization.     

A comparison of the PAI and MMPI-2 as predictors of faking bad in college students

Both the Minnesota Multiphasic Personality Inventory-2 (MMPI-2; Butcher et al., 2001) and Personality Assessment Inventory (PAI; Morey, 1991) offer a large set of scales devoted to the identification of response styles. This study directly compared the effectiveness of the 2 inventories as indicators of overreporting. The 2 measures were administered to 52 college students instructed to fake bad under conditions describing either a forensic (n = 24) or psychiatric (n = 28) setting as well as to 432 psychiatric patients. Results indicated that the MMPI-2 F - K index and Fp Scale were the best single indicators of a faking bad response style and that the MMPI-2 scales were the better indicators as a set. However, the PAI scales demonstrated a significant level of incremental validity over the MMPI-2 indicators in every analysis conducted. The findings suggest that either inventory offers an effective approach to the detection of overreporting, and administering both inventories can enhance the accuracy of prediction further.     

The costs of doing two things at once for young and older adults: talking while walking,finger tapping,and ignoring speech or noise

Young and older adults provided language samples in response to questions while walking, finger tapping, and ignoring speech or noise. The language samples were scored on 3 dimensions: fluency, complexity, and content. The hypothesis that working memory limitations affect speech production by older adults was tested by comparing baseline samples with those produced while the participants were performing the concurrent tasks. There were baseline differences: Older adults' speech was less fluent and less complex than young adults' speech. Young adults adopted a different strategy in response to the dual-task demands than older adults: They reduced sentence length and grammatical complexity. In contrast, older adults shifted to a reduced speech rate in the dual-task conditions.
