Age, time of testing, and proactive interference.

A four-list version of a release from proactive interference paradigm was used to assess the degree to which older and younger adults tested at optimal and nonoptimal times of day are vulnerable to interference effects in memory, effects that may increase at nonoptimal times. Morning type older adults and Evening type younger adults were tested either early in the morning or late in the afternoon. Standard buildup and release effects were shown for all age groups except for older adults tested in the afternoon; they failed to show release. Recall and intrusion data suggested that older adults are more vulnerable to proactive interference than younger adults and that for older adults at least, interference effects are heightened at nonoptimal times of day. The data are discussed in terms of an inhibitory model of control over the contents of working memory (Hasher, Zacks, & May, 1999).     

Religious Geography and County‐Level Sex Ratios in China

The sex ratio at birth in China is highly imbalanced in favor of boys. Past research on sex ratios in China emphasizes economic factors for their weakening effect on the Confucian tradition of son preference. Research in the sociology of religion suggests that religious geography may affect sex ratios through the spill‐over of religious teachings to those living in areas dominated by a religious tradition. To assess this linkage, we investigate the relationship between religious geography and county‐level child sex ratios using the 2000 China Population Census and the 2004 China Economic Census, the most complete and recent data available on religious presence in China. Applying spatial analyses of 2,685 counties (over 90% of all counties), we find that counties with a greater presence of Daoist temples have more imbalanced (male‐biased) sex ratios, whereas a greater presence of Buddhist temples and Islamic mosques is associated with less imbalanced sex ratios.     

Outcomes of a practical approach for improving conversation skills in adults with autism

Many individuals with autism spectrum disorder (ASD) have deficits in conversation skills that can interfere with the development of personal and professional relationships. Further research is needed on efficient interventions for targeting conversation skills in adults with ASD and for evaluating the social validity of the outcomes. In this study, 2 practitioners implemented a 4‐week training program for 5 adults with ASD that combined individualized computer‐based instruction (CBI) and practice with peers to promote the acquisition, maintenance, and generalization of conversation skills. Training was associated with improvements in 12 of 13 skills across participants. These findings, along with peer ratings of the participants' conversation skills, suggest that this model is a promising, socially valid approach for improving conversation skills in adults with ASD.     

Development of a Health Related Quality of Life Measure for Adolescents and Young Adults Following Invasive Meningococcal Disease

This study describes the key areas that matter to adolescent survivors of Invasive Meningococcal Disease (IMD). Satisfaction with Life After Meningitis is a brief multidimensional measure of health related quality of life that is reliable and correlates with criterion variables in a theoretically meaningful way. To develop a Health Related Quality of Life (HRQoL) measure for adolescent and young adult survivors of (IMD) we used a cross-sectional study and focus groups. The study was conducted in two phases. In Phase 1 a pool of potential items were generated based on the following: a review of existing measures, focus groups with IMD survivors, and an expert group consultation. Phase 2 involved administration of the questionnaire to a sample of adolescent and young adult IMD survivors. Factor analysis suggested a correlated four factor solution: Wellbeing, Positive about Future, Social Support, and Confidence. These factors were significantly correlated in a theoretically predictable way with scores from the Beck Depression Inventory (correlations ranged from ?0.77 to ?0.81) and the eight domains of the SF-36 Health Survey (correlations ranged from 0.32 to 0.79). The reliability of all subscales was high ranging from 0.85 to 0.92. The Satisfaction with Life After Meningitis (SLAM) questionnaire is a HRQoL self-report measure that produces reliable scores and is appropriate for use with young survivors of IMD. There is also evidence of concurrent validity with existing measures of physical and psychological well-being.     

Lifting the curtain on the Wizard of Oz: biased voice-based impressions of speaker size

The consistent, but often wrong, impressions people form of the size of unseen speakers are not random but rather point to a consistent misattribution bias, one that the advertising, broadcasting, and entertainment industries also routinely exploit. The authors report 3 experiments examining the perceptual basis of this bias. The results indicate that, under controlled experimental conditions, listeners can make relative size distinctions between male speakers using reliable cues carried in voice formant frequencies (resonant frequencies, or timbre) but that this ability can be perturbed by discordant voice fundamental frequency (F-sub-0, or pitch) differences between speakers. The authors introduce 3 accounts for the perceptual pull that voice F-sub-0 can exert on our routine (mis)attributions of speaker size and consider the role that voice F-sub-0 plays in additional voice-based attributions that may or may not be reliable but that have clear size connotations.     

The value-congruence model of memory for emotional experiences: an explanation for cultural differences in emotional self-reports

In 3 studies, the authors found support for the value-congruence model that accounts for cultural variations in memory for emotional experiences. In Study 1, the authors found that in the made-in-the-U.S. scenario condition, European Americans were more accurate than were Asian Americans in their retrospective frequency judgments of emotions. However, in the made-in-Japan scenario condition, European Americans were less accurate than were Asian Americans. In Study 2, the authors demonstrated that value orientation mediates the CulturexType of Event congruence effect. In Study 3 (a daily event sampling study), the authors showed that the congruence effect was explained by the importance of parental approval. In sum, emotional events congruent with personal values remain in memory longer and influence retrospective frequency judgments of emotion more than do incongruent events.     

Practice evoking the flexor carpi radialis h-reflex: a guideline for proficiency

The purpose of this research was to identify the number of sessions required for a new investigator to become proficient at evoking an H-reflex in the flexor carpi radialis (FCR), in comparison to an experienced investigator. 31 students from Brock University in the greater Niagara region (16 women M age = 32.2, SD = 8.9 yr.; 15 men M age = 27.8, SD = 7.8 yr.) with no known neurological disorders volunteered and completed two test sessions performed by either an experienced or a novice investigator. In randomized order, both investigators stimulated each subject's median nerve 10 times, once every 15 sec. Each session included the measurement of the subject's flexor carpi radialis maximal M-wave amplitude and H-reflex amplitude and latency with surface electromyographic electrodes. The intraclass correlation coefficients (ICC) indicated an adequate correlation between investigators for both M-wave maximal amplitude and H-reflex at 5% of the M-wave maximal amplitude (.84 and .70, respectively). However, there was a low correlation (.38) between the latency values obtained by the two investigators. The peak-to-peak amplitudes of the H-reflex and M-wave do not appear to be influenced by experience of the tester. The latency of the response, however, appears to have an associated learning curve, improving in consistency with increasing practice of tester.     

Critical Incidents in the Professional Lives of First Year MFT Students

First year MFT students engaged in a journaling project, selecting one event daily which captured something about being a student, including the process of therapy, consultation, and supervision, that struck them as important in terms of their professional development. On reflection, the students saw therapeutic success and professional confidence as systemic products of a variety of contextual factors: transient and enduring aspects of the self and the client, faculty, peer, and family influences, and treatment setting and program factors. Students and faculty experienced this formative self study as valuable and believe that it should be done at the beginning, middle, and end of an educational program and the results shared with both faculty and students.     

Negative priming for spatial location?

The term negative priming has been used to describe the deleterious consequences for performance when the current target shares properties with an ignored distractor from the previous trial. Location-based negative priming was first reported by Tipper, Brehaut, and Driver (1990) who used a prime-probe procedure wherein the task was to localize targets defined by their identity (shape). Design imbalances in this seminal study, and others, are illustrated and it is indicated how these might have contaminated the reported effects. The findings, from three experiments using an unbiased design, suggest that negative priming in the spatial location procedure may be more closely related to inhibition of return (IOR), or to the automatic attraction of attention by new objects, than to the concepts of distractor inhibition, episodic retrieval, and feature mismatch, which have traditionally been used to explain negative priming for spatial location.
