Prevalence of borderline personality disorder and its clinical correlates in Chinese patients with recent deliberate self-harm

This study examined the point prevalence of Borderline Personality Disorder (BPD) and its clinical correlates in patients with recent deliberate self-harm (DSH) in Hong Kong. A representative consecutive sample (n = 160) of patients with DSH referred to Prince of Wales Hospital from April 1, 2007 to March 31, 2008 was recruited. Their BPD status was determined according to the BPD subscale of the Chinese version of Structured Clinical Interview for DSM-IV Axis II Personality Disorders (SCID-II). The point prevalence of BPD was calculated. Subjects with and without BPD were compared in terms of demographic and clinical characteristics. Thirty out of 160 (18.8%) DSH patients were found to suffer from BPD. DSH patients with BPD were more likely to be female (p = .020), more often reported history of childhood physical (p = 0.043) and sexual abuse (p < 0.001), history of past DSH (p = 0.010), being younger at first DSH (p = 0.039), and more likely to suffer from current alcohol and substance use disorder (p = 0.043) and eating disorder (p = 0.040) than those without BPD. Being female, having history of childhood sexual abuse and current alcohol and substance use disorder were found to be independent predictors of BPD status by binary logistic regression.     

Looking to the future: will behavior analysis survive and prosper?

Behavior analysis as a discipline currently is doing relatively well. How it will do in the future is unclear and depends on how the field, and the world at large, changes. Five current characteristics of the discipline that appear to reduce the probability that it will survive and prosper are discussed and suggestions for improvement are offered. The areas of concern are (a) the small size and limited power of the discipline, (b) the growing focus of applied behavior analysis on autism spectrum disorders and little else, (c) the esoteric nature of much basic research, (d) the proliferation of "applied" research that really isn't applied, and (e) the widespread use of imprecise and potentially harmful technical language.     

Cognitive systems struggling for word order

We argue that the grammatical diversity observed among the world’s languages emerges from the struggle between individual cognitive systems trying to impose their preferred structure on human language. We investigate the cognitive bases of the two most common word orders in the world’s languages: SOV (Subject–Object–Verb) and SVO. Evidence from language change, grammaticalization, stability of order, and theoretical arguments, indicates a syntactic preference for SVO. The reason for the prominence of SOV languages is not as clear. In two gesture-production experiments and one gesture comprehension experiment, we show that SOV emerges as the preferred constituent configuration in participants whose native languages (Italian and Turkish) have different word orders. We propose that improvised communication does not rely on the computational system of grammar. The results of a fourth experiment, where participants comprehended strings of prosodically flat words in their native language, shows that the computational system of grammar prefers the orthogonal Verb–Object orders.     

A Psychometric Evaluation of Poloma and Pendleton's (1991) and Ladd and Spilka's (2002, 2006) Measures of Prayer

Prayer has increasingly been used as an empirical measure of religiosity. Recent developments include Ladd and Spilka's Inward, Outward and Upward Prayer Scale, which measures what respondents think about while praying, and Poloma and Pendleton's Measure of Prayer Type, which measures four different dimensions of prayer as well as degree of intimacy with the divine. The present study provides a factor analytical evaluation of both measures, including an examination of total scale and subscale reliability. The measures were administered to a sample of 518 Irish respondents. Although the total scales and subscales were found to be reliable, confirmatory factor analysis revealed that the hypothesized factor structures were a less than optimal fit of the data, while correlational analysis revealed a conceptual overlap between the measures.     

The development of memory maintenance: Children’s use of phonological rehearsal and attentional refreshment in working memory tasks

Past research suggests that children begin to phonologically rehearse at around 7 years of age. Less is known regarding the development of refreshment, an attention-based maintenance mechanism. Therefore, the use of these two maintenance methods by 6- and 8-year-olds was assessed using memory span tasks that varied in their opportunities for maintenance activity. Experiment 1 showed that nonverbal processing impaired both groups’ performance to similar extents. Experiment 2 employed phonologically similar or dissimilar memory items and compared the effects of verbal versus nonverbal processing on recall. Both groups showed evidence of phonological maintenance under nonverbal processing but not under verbal processing. Furthermore, nonverbal processing again impaired recall. Verbal processing was also more detrimental to performance in 8-year-olds than in 6-year-olds. Together, the results suggest that nonverbal processing impairs recall by obstructing refreshment and that developmental change in maintenance between 6 and 8 years of age consists primarily of an increase in phonological rehearsal.     

Edges,colour and awareness in blindsight

It remains unclear what is being processed in blindsight in response to faces, colours, shapes, and patterns. This was investigated in two hemianopes with chromatic and achromatic stimuli with sharp or shallow luminance or chromatic contrast boundaries or temporal onsets. Performance was excellent only when stimuli had sharp spatial boundaries. When discrimination between isoluminant coloured Gaussians was good it declined to chance levels if stimulus onset was slow. The ability to discriminate between instantaneously presented colours in the hemianopic field depended on their luminance, indicating that wavelength discrimination totally independent of other stimulus qualities is absent. When presented with narrow-band colours the hemianopes detected a stimulus maximally effective for S-cones but invisible to M- and L-cones, indicating that blindsight is mediated not just by the mid-brain, which receives no S-cone input, or that the rods contribute to blindsight. The results show that only simple stimulus features are processed in blindsight.     

Mindfulness Training for Parents and Their Children With ADHD Increases the Children’s Compliance

Children with ADHD are often non-compliant with parental instructions. Various methods have been used to reduce problem behaviors in these children, with medication and manipulation of behavioral contingencies being the most prevalent. An objection often raised by parents is that these management strategies require them to impose external control on the children which not only results in the children not learning self-control strategies, but also does not enhance positive interactions between them and their parents. Studies have shown that providing mindfulness training to parents, without a focus on reducing problem behaviors, can enhance positive interactions with their children and increase their satisfaction with parenting. We were interested to see what effects giving mindfulness training to two mothers, and subsequently to their children, would have on compliance by the children. Using a multiple baseline across mothers and children design, we found that giving a mother mindfulness training enhanced compliance by her child. When the children were subsequently given similar training, compliance increased even more markedly, and was maintained during follow-up. The mothers reported associated increases in satisfaction with the interactions with their children and happiness with parenting. We suspect that the mindfulness training produces personal transformations, both in parents and children, rather than teaching strategies for changing behavior.     

Landmark use by Clark’s nutcrackers (Nucifraga columbiana): influence of disorientation and cue rotation on distance and direction estimates

Many species have been shown to encode multiple sources of information to orient. To examine what kinds of information animals use to locate a goal we manipulated cue rotation, cue availability, and inertial orientation when the food-storing Clark’s nutcracker (Nucifraga columbiana) was searching for a hidden goal in a circular arena. Three groups of birds were used, each with a different goal–landmark distance. As the distance between the goal and the landmark increased, nutcrackers were less accurate in finding the correct direction to the goal than they were at estimating the distance (Experiment 1). To further examine what cues the birds were using to calculate direction, the featural cues within the environment were rotated by 90° and the birds were either oriented when searching (Experiments 2 and 3) or disoriented (Experiment 3). In Experiment 4, all distinctive visual cues were removed (both internal and external to the environment), a novel point of entry was used and the birds were either oriented or disoriented. We found that disorienting the nutcrackers so that they could not use inertial cues did not influence the birds’ total search error. The birds relied heavily but not completely on cues within the environment, as rotating available cues caused them to systematically shift their search behavior. In addition, the birds also relied to some extent on Earth-based cues. These results show the flexible nature of cue use by the Clark’s nutcracker. Our study shows how multiple sources of spatial information may be important for extracting multiple bearings for navigation.     

Do Verbal Interactions with Infants During Electronic Media Exposure Mitigate Adverse Impacts on their Language Development as Toddlers?

The goal of this study was to determine whether verbal interactions between mothers and their 6-month-old infants during media exposure ('media verbal interactions') might have direct positive impacts, or mitigate any potential adverse impacts of media exposure, on language development at 14 months. For 253 low-income mother-infant dyads participating in a longitudinal study, media exposure and media verbal interactions were assessed using 24-hour recall diaries. Additionally, general level of cognitive stimulation in the home [StimQ] was assessed at 6 months and language development [Preschool Language Scale-4] was assessed at 14 months. Results suggest that media verbal interactions play a role in the language development of infants from low-income, immigrant families. Evidence showed that media verbal interactions moderated adverse impacts of media exposure found on 14-month language development, with adverse associations found only in the absence the these interactions. Findings also suggest that media verbal interactions may have some direct positive impacts on language development, in that media verbal interactions during the co-viewing of media with educational content (but not other content) were predictive of 14-month language independently of overall level of cognitive stimulation in the home.
