The Personality Assessment Inventory Drug Problems Scale: a validity analysis

An analysis of the relationship among the Personality Assessment Inventory (PAI; Morey, 1991, 1996) Drug Problems (DRG) scale scores, the Addiction Severity Index (ASI; McLellan et al., 1992) scores, and urine toxicology reports revealed that the PAI Drug Problem scale scores of 100 substance-using and substance-abusing men and women were distributed in a manner that was in agreement with the guidelines suggested by Morey (1991, 1996) in the PAI manual. There were significant correlations among the PAI DRG scale and the ASI scales related to frequency of use, negative consequences of use, and need and desire for treatment. Overall, higher scores did reflect both more serious involvements with drug use and more serious problems as a consequence of their involvement.     

The haptic Müller-Lyer illusion in sighted and blind people

We examined the effect of visual experience on the haptic Müller-Lyer illusion. Subjects made size estimates of raised lines by using a sliding haptic ruler. Independent groups of blind-folded-sighted, late-blind, congenitally blind, and low-vision subjects judged the sizes of wings-in and wings-out stimuli, plain lines, and lines with short vertical ends. An illusion was found, since the wings-in stimuli were judged as shorter than the wings-out patterns and all of the other stimuli. Subjects generally underestimated the lengths of lines. In a second experiment we found a nonsignificant difference between length judgments of raised lines as opposed to smooth wooden dowels. The strength of the haptic illusion depends upon the angles of the wings, with a much stronger illusion for more acute angles. The effect of visual status was nonsignificant, suggesting that spatial distortion in the haptic Müller-Lyer illusion does not depend upon visual imagery or visual experience.     

Young children can extend motion verbs to point-light displays

In the first study using point-light displays (lights corresponding to the joints of the human body) to examine children's understanding of verbs, 3-year-olds were tested to see if they could perceive familiar actions that corresponded to motion verbs (e.g., walking). Experiment 1 showed that children could extend familiar motion verbs (e.g., walking and dancing) to videotaped point-light actions shown in the intermodal preferential looking paradigm. Children watched the action that matched the requested verb significantly more than they watched the action that did not match the verb. In Experiment 2, the findings of Experiment 1 were validated by having children spontaneously produce verbs for these actions. The use of point-light displays may illuminate the factors that contribute to verb learning.     

Intimate partner stalking and femicide: urgent implications for women's safety

This study describes the type and extent of intimate partner stalking and threatening behaviors that occurred within 12 months prior to a major assault or attempted or actual partner femicide and specifies which behaviors were associated with an increased risk of potential or actual lethality.The design was a ten-city case-control study of 821 women: 384 abuse victims and 437 attempted or actual femicide informants. Data were derived using a 16-item inventory. Logistic regressions, with adjustments for demographic variables, were used to identify the significant perpetrator behaviors associated with attempted/actual femicide.Women who reported the perpetrator followed or spied on them were more than twice as likely t o become attempted/actual femicide victims. Threats by the perpetrator to harm the children if the woman left or did not return to the relationship place the woman at a ninefold increase in the risk of attempted/actual femicide. Conclusions are that certain stalking and threatening behaviors are strong risk factors for lethality, and women must be so advised.     

Putting things into perspective: individual differences in working-memory span and the integration of information

An important function of working memory is the integration of incoming information into an appropriate model of the contextual situation. We hypothesized that individual variability in working-memory function (estimated using Engle's operation-span measure) may lead to differential reactivity to a changing context. We recorded event-related brain potentials (ERPs) and reaction-time measures to stimuli embedded in long stimulus series (two auditory discrimination tasks), and examined the participants' responses in relation to how the current stimuli fit with the context generated by the previous stimuli. In both tasks, participants with low working-memory span scores showed larger brain responses as a function of variations in the local stimulus sequence than participants with high span scores. These data suggest that the low working-memory span group is more affected by the local stimulus sequence than the high span group, possibly because they are more easily swayed by ongoing changes and are therefore less capable of maintaining their attention on the overall sequence.     

Globalising counselling: humanistic counselling in Kenya

This paper explores the application of a Western, psychologically-based model of counselling and counselling training in contexts where the social and cultural conditions differ from mainstream Western societies. A group of Kenyan trainee counsellors following such a course are interviewed about their experience of training. The interview data are analysed to provide a tentative answer to the question of the appropriateness in a Kenyan cultural milieu of a humanistic counselling training model developed in the UK. It is concluded that such application is possible and desirable, if it is undertaken as shared and respectful learning between trainers and trainees.     

The helping relationship and program participation in early childhood home visiting

As researchers have focused on better understanding those circumstances under which home visiting can lead to positive effects on parent and child outcomes, there has been growing interest in examining variation in the experiences of families within these programs, including the quality of the helping relationships between home visitors and parents. The current study examined how participating mothers perceive the helping relationship, using information collected from the Early Head Start National Research and Evaluation Project. Results suggest that although maternal report of the helping relationship is biased towards positive ratings, it remains a significant predictor of program participation, over and above general program satisfaction. Implications for measurement development and program interventions are discussed.     

Young children associate novel words with complex objects rather than salient parts

How do children learn associations between novel words and complex perceptual displays? Using a visual preference procedure, the authors tested 12- and 19-month-olds to see whether the infants would associate a novel word with a complex 2-part object or with either of that object's parts, both of which were potentially objects in their own right and 1 of which was highly salient to infants. At both ages, children's visual fixation times during test were greater to the entire complex object than to the salient part (Experiment 1) or to the less salient part (Experiment 2)--when the original label was requested. Looking times to the objects were equal if a new label was requested or if neutral audio was used during training (Experiment 3). Thus, from 12 months of age, infants associate words with whole objects, even those that could potentially be construed as 2 separate objects and even if 1 of the parts is salient.     

Physician Beliefs about Physical and Mental Competency of Patients Applying for Concealed Weapon Permits

Law enforcement officials have asked health care providers to evaluate patient applications for concealed weapon permits. The current study was designed to examine physician beliefs regarding competency to carry a concealed weapon for patients with specific physical and mental conditions. Among 222 North Carolina physicians who participated in this survey (40% response rate), large variation and uncertainty existed for determining competency. Physicians most frequently chose mild dementia, post-traumatic stress disorder, and recent depression as conditions that would render a patient not competent to carry a concealed weapon. Male physicians and those owning a gun were more likely to deem a patient competent. Almost a third of physicians were unsure about competence for most conditions. Physicians asked to assess competency of patients to carry a concealed weapon have quite disparate views on competency and little confidence in their decisions. If physicians are expected to assess patient competence to carry a concealed weapon, more objective criteria and training are needed. Copyright © 2015 John Wiley & Sons, Ltd.
