Assessment of Rorschach dependency measures in female inpatients diagnosed with borderline personality disorder

The psychometric properties and predictive validity of the Dependency Index (DI; Hilsenroth & Bornstein, 2002) and the Rorschach Oral Dependency Scale (ROD; Masling, Rabie, & Blondheim, 1967) were examined to determine if these implicit measures of dependency predict observable attachment-seeking behavior in 66 female inpatients diagnosed with borderline personality disorder. Results indicate that both scales produce excellent reliability estimates. The DI and ROD yield adequate base rates, and the distributions of scores approximate normal distributions. The DI was predictive of nursing staff observation of positive attachment/treatment compliance (r = .28, p = .02) but not excessive isolation. By contrast, the ROD predicted positive attachment/treatment compliance (r = .38, p = .002) and excessive isolation (r = -.35, p = .004). Texture responses predicted excessive isolation (r = -.25, p = .05). Discriminant validity was supported when neither dependency measure predicted hostile interactions or self-destructive behaviors. Hierarchical regression analyses revealed that the ROD demonstrated incremental validity over the DI and select Comprehensive System (Exner, 1993) variables associated with dependency.     

The General Health Questionnaire and Eysenck's three-dimensional model of personality

A sample of 115 men and women between the ages of 20 and 60 completed the 30-item General Health Questionnaire together with the short-form Revised Eysenck Personality Questionnaire. The data indicate psychological distress so assessed is correlated .43 (p <.001) with Neuroticism and -.26 (p <.01) with Introversion but is unrelated to Psychoticism scores.     

Evaluation of behavioral skills training for teaching abduction-prevention skills to young children

This study examined the effectiveness of individual behavioral skills training in conjunction with in situ training in teaching 13 preschool children abduction prevention skills. Children's performance was measured during baseline, training, and at 2-week, 1-month, and 3-month follow-ups using in situ assessments in which abduction prevention skills were measured in naturalistic settings. Results revealed that all the children learned the skills and all the children available at the 2-week and 1-month follow-ups maintained the skills at criterion level. All but 3 children's criterion-level performances were maintained at the 3-month follow-up as well.     

Teaching safety skills to children to prevent gun play: an evaluation of in situ training

This study evaluated behavioral skills training with added in situ training for teaching safety skills to prevent gun play. Following baseline, each child received two sessions of behavioral skills training and one in situ training session. Additional in situ training sessions were conducted until the child exhibited the safety skills (don't touch the gun, get away, and tell an adult). All children acquired and maintained the safety skills at a 3-month follow-up. In addition, of the 7 children assessed in a dyad situation, all exhibited the correct skills in the presence of another child.     

The cultural grounding of personal relationship: enemyship in North American and West African worlds

Three studies investigated the implicit constructions of reality associated with cultural differences in enemyship (personal relationship of hatred, malice, and sabotage). Results of interview (Study 1; N = 98) and questionnaire (Study 2; N = 166) research indicated that enemyship was more prominent among Ghanaian participants than among U.S. participants. Additional evidence located a potential source of these differences in different constructions of relationship. Responses linked the prominence of enemyship to constructions of relationship as inherent, enduring connection (interdependent models). Responses linked the sense of freedom from enemyship to constructions of relationship as the discretionary product of atomistic selves (independent models). An experiment among Ghanaian participants (Study 3; N = 48) provided evidence that increasing experience of inherent connection can be sufficient to increase accessibility of enemyship. Results help to illuminate the cultural grounding of personal relationship and other phenomena that are typically invisible in mainstream theory and research.     

Serial position effects in recognition memory for odors: A reexamination

Seven experiments examined recognition memory for sequentially presented odors. Following Reed (2000), participants were presented with a sequence of odors and then required to identify an odor from the sequence in a test probe comprising 2 odors. The pattern of results obtained by Reed (2000, although statistically marginal) demonstrated enhanced recognition for odors presented at the start (primacy) and end (recency) of the sequence: a result that we failed to replicate in any of the experiments reported here. Experiments 1 and 3 were designed to replicate Reed (2000), employing five-item and seven-item sequences, respectively, and each demonstrated significant recency, with evidence of primacy in Experiment 3 only. Experiment 2 replicated Experiment 1, with reduced interstimulus intervals, and produced a null effect of serial position. The ease with which the odors could be verbally labeled was manipulated in Experiments 4 and 5. Nameable odors produced a null effect of serial position (Experiment 4), and hard-to-name odors produced a pronounced recency effect (Experiment 5); nevertheless, overall rates of recognition were remarkably similar for the two experiments at around 70%. Articulatory suppression reduced recognition accuracy (Experiment 6), but recency was again present in the absence of primacy. Odor recognition performance was immune to the effects of an interleaved odor (Experiment 7), and, again, both primacy and recency effects were absent. There was no evidence of olfactory fatigue: Recognition accuracy improved across trials (Experiment 1). It is argued that the results of the experiments reported here are generally consistent with that body of work employing hard-to-name visual stimuli, where recency is obtained in the absence of primacy when the retention interval is short.     

Acoustic mechanisms of note-type perception in black-capped chickadee (Poecile atricapillus) calls

Acoustic communication in black-capped chickadees (Poecile atricapillus) has been studied intensively, the "chick-a-dee" call being among the most well described. This call consists of 4 note types; chickadees perceive these notes as open-ended categories and do so in a continuous manner, with As more similar to Bs and Bs more similar to Cs. Acoustic features contributing to the note-type differentiation are unknown. Recent analyses suggested that certain acoustic features may play a role in note-type classification. Here, the authors tested black-capped chickadees in an operant-conditioning paradigm to determine which features were controlling note-type perception. The results suggest that the note pitch and the frequency modulation in the initial portion of the note control the perception of note types.     

Life history and social learning: megapode chicks fail to acquire feeding preferences from conspecifics

Australian brush-turkeys, Alectura lathami, are birds with an unusual life history: The young receive no parental care and first encounter conspecifics at an unpredictable age. Brush-turkey chicks that were 3-4 days old were presented with a robot model that appeared to feed from a distinctively colored dish. In control training trials, chicks saw a robot standing next to a different dish and scanning from side to side. Chicks expressed a strong tendency to feed from dishes of the type indicated by the pecking robot, but this effect proved ephemeral. Brush-turkeys hence appear to show no social learning under conditions that inculcate stable preferences in other galliforms such as chickens, suggesting that life history plays an important role in the evolution of learning.     

Worry and Pathological Worry in Patients with Psoriasis: Cross Sectional and Longitudinal Analyses of the Penn State Worry Questionnaire (PSWQ) in Four Samples of Patients

The purpose of the present study was to examine the psychometric properties of the Penn state Worry Questionnaire (PSWQ) in patients with psoriasis. A series of cross-sectional and longitudinal studies were undertaken to assess the reliability, stability and validity of the measure. Patients with psoriasis from four samples (consecutive attendees, anxious patients, depressed patients, and 6-month follow-up of consecutive attendees) completed the PSWQ and measures assessing related constructs of anxiety and depression (HADS) and coping (COPE). The clinical severity of patients psoriasis was also assessed by dermatologists using the Psoriasis Area and Severity Index (PASI). Exploratory factor analysis was undertaken and receiver operator characteristic (ROC) analyses were used to examine the clinical utility of the PSWQ cut-off score for normal and pathological worry. Exploratory factor analysis suggested that the PSWQ is essentially unidimensional in patients with psoriasis. Intraclass correlation demonstrated that, over a 6-month period, the reproducibility of the PSWQ total scale was good in patients with anxiety and moderate in patients with depression. ROC analysis suggested that the optimum cutoff differentiating pathological worry was > 60, which is commensurate with findings in adult mental health more generally. The PSWQ cutoff for pathological worry showed a lower specificity for depression than anxiety. The PSWQ is an appropriate measure of pathological worry in patients with psoriasis. The cutoff on the scale for pathological worry demonstrates appropriate conceptual overlap with subordinate distress categories of anxiety and depression.     

An open-source LabVIEW application toolkit for phasic heart rate analysis in psychophysiological research

The cardiovascular system has been extensively measured in a variety of research and clinical domains. Despite technological and methodological advances in cardiovascular science, the analysis and evaluation of phasic changes in heart rate persists as a way to assess numerous psychological concomitants. Some researchers, however, have pointed to constraints on data analysis when evaluating cardiac activity indexed by heart rate or heart period. Thus, an off-line application toolkit for heart rate analysis is presented. The program, written with National Instruments’ LabVIEW, incorporates a variety of tools for off-line extraction and analysis of heart rate data. Current methods and issues concerning heart rate analysis are highlighted, and how the toolkit provides a flexible environment to ameliorate common problems that typically lead to trial rejection is discussed.
