Family Therapy With Irish-Americans

This paper presents a paradigm for understanding the cultural values and family patterns of Irish-American families and offers suggestions for clinical intervention. Families' correspondence to the model described will depend upon their level of acculturation, socioeconomic status, and other contextual factors. The paradigm suggests a number of issues that may create difficulties for the therapist and for the family in therapy. In general, behavioral techniques, Bowen systems therapy, and strategic interventions may be more useful than techniques emphasizing expression of emotions in therapy or direct attempts to alter communication or family behavior in therapy sessions, as used in structural therapy.     

Assessment of anxiety in older adults: a community-based survey and comparison with younger adults

The reliability and validity of existing anxiety self-report scales in elderly adults has not been adequately established, and the phenomenology of anxiety in older adults is largely unknown. In the present study, three anxiety scales and measures of depression and somatization were used to compare symptoms between older (n = 84, mean age = 75.3) and younger (n = 48, mean age = 40.3) community-dwelling adults. Results showed that the anxiety scales demonstrated good internal consistency in both age groups, although the reliabilities of the Fear Questionnaire subscales ranged from poor to good. Convergent and divergent validity were found to be variable in the older group, but this may reflect differences in anxiety as it occurs in older persons rather than psychometric problems. Anxiety symptoms did not vary with age, and levels of anxiety also remained constant. However, gender differences were found only within the older age group, with women reporting more anxiety than men. Findings are discussed with respect to current conceptualizations of anxiety in older people, as well as implications for future research.     

Determinants of cognitive outcomes of perinatal and childhood stroke: A review

Our understanding of cognitive and behavioral outcomes of perinatal and childhood stroke is rapidly evolving. A current understanding of cognitive outcomes following pediatric stroke can inform prognosis and direct interventions and our understanding of plasticity in the developing brain. However, our understanding of these outcomes has been hampered by the notable heterogeneity that exists amongst the pediatric stroke population, as the influences of various demographic, cognitive, neurological, etiological, and psychosocial variables preclude broad generalizations about outcomes in any one cognitive domain. We therefore aimed to conduct a detailed overview of the published literature regarding the effects of age at stroke, time since stroke, sex, etiology, lesion characteristics (i.e., location, laterality, volume), neurologic impairment, and seizures on cognitive outcomes following pediatric stroke. A key theme arising from this review is the importance of interactive effects among variables on cognitive outcomes following pediatric stroke. Interactions particularly of note include the following: (a) age at Stroke x Lesion Location; (b) Lesion Characteristics (i.e., volume, location) x Neurologic Impairment; (c) Lesion Volume x Time Since Stroke; (d) Sex x Lesion Laterality; and (e) Seizures x Time Since Stroke. Further, it appears that these relationships do not always apply uniformly across cognitive domains but, rather, are contingent upon the cognitive ability in question. Implications for future research directions are discussed.     

MEASUREMENT ERROR IN RESEARCH ON HUMAN RESOURCES and FIRM PERFORMANCE: HOW MUCH ERROR IS THERE AND HOW DOES IT INFLUENCE EFFECT SIZE ESTIMATES?

Studies of the relationship between human resource (HR) practices and firm performance typically use a single respondent to assess firm level HR practices or HR effectiveness. However, previous research in other substantive areas suggests that rater differences are a potentially important source of measurement error. We demonstrate analytically the potential consequences of both random and systematic measurement error in research on HR and firm performance. However, our main focus is on random error and we show how generalizability theory can be applied to obtain better estimates of reliability by simultaneously recognizing multiple sources (e.g., items, raters) of random measurement error. These more inclusive reliability estimates, in turn, offer the possibility of more precisely quantifying substantive relationships in the HR and firm performance literature. In our sample, reliabilities (as estimated by generalizability coefficients) for single-rater assessments of HR variables were generally below .50. This degree of measurement error, if present in substantive studies on HR and firm performance, could lead to considerable bias, given that an unstandardized regression coefficient is corrected for measurement error in the independent variable by dividing by its reliability coefficient (not its square root). We also found only limited convergent validity between HR and line managers ratings of a second type of HR measure, HR effectiveness. In general, our findings suggest that future researchers need to devote greater attention to measurement error and construct validity issues. Our study provides an example of how generalizability theory can be useful in this pursuit.     

A longitudinal study of temperament in infancy: stability and convergence of measures

This study analyzed the stability of individual differences in temperament and the convergence between two kinds of measures used to assess temperament: maternal report (IBQ and TBAQ), and laboratory measures. Sixty children were assessed at 3, 6, 9 and 12 months of age and their mothers' reports were collected at the same time. Mothers' perceptions of their children's temperament showed high stability across the range of children's ages. In laboratory, however, moderate stability was found only for the period between 9 and 12 months. Convergence between laboratory and maternal report measures was found at 6 and 12 months.

The global precedence effect is not affected in inhibition of return

This study assessed whether inhibitory processes occurring in IOR affect perceptual processing of hierarchically organised stimuli. Experiment 1 used a global/local task that presented stimuli to the left or the right side. Results showed a global task advantage and a larger interference in the local than in the global task—the global precedence effect (GPE). These effects were larger than in previous studies using centrally presented stimuli, which suggests a greater involvement of low spatial frequency analysis with peripheral than with central stimuli. Experiment 2 combined the global/local task with IOR. Results replicated those of Experiment 1 but there was no interaction with stimulus location. That is, the GPE was not affected in IOR. Thus, we conclude that the GPE and inhibitory processing occurring in IOR are subserved by different mechanisms.     

Processing of “unattended” threat-related information: Role of emotional content and context

Unpleasant, pleasant, or neutral visual scenes served as a context for the presentation of threat-related, positive, and neutral words. On each trial, 2 simultaneous prime words (one foveal, i.e., at fixation, and one parafoveal, i.e., 2.2° apart) appeared for 150 ms, followed by a foveally presented probe word in a lexical decision task. Results showed facilitation in response times for probe threat words when primed by an identical parafoveal word, in comparison with priming by an unrelated parafoveal word, and this effect was enhanced in an emotionally congruent unpleasant context. In contrast, no parafoveal effect appeared for positive words, even in a pleasant context. This reveals parallel processing of threat-related words outside the focus of attention.     

BRIEF REPORT: LATENCY FUNCTIONAL ANALYSIS OF ELOPEMENT

Elopement is a potentially dangerous problem behavior prevalent among individuals with developmental disabilities. However, functional analysis of elopement presents unique challenges including potential confounds because of the need for participant retrieval during functional analysis sessions. In the current study, we implemented a latency functional analysis with an eight‐year‐old child with an intellectual disability, in which the dependent measure was latency to elopement. Following the latency functional analysis, a functional communication intervention was developed and its effectiveness in decreasing elopement was evaluated using an ABAB design. Findings suggest that a functional analysis of latency may be a suitable methodology to identify the operant function of elopement. Copyright © 2013 John Wiley & Sons, Ltd.     

The effects of sleep deprivation on the attentional functions and vigilance

The study of sleep deprivation is a fruitful area of research to increase our knowledge of cognitive functions and their neural basis. In the current work, 26 healthy young adults participated in a sleep deprivation study, in which the Attentional Networks Test for Interactions and Vigilance (ANTI-V) was performed at 10a.m. after a night of normal sleep and again at 10 a.m. after 25.5-27.5 h of total sleep deprivation. The ANTI-V is an experimental task that provides measures of alerting, orienting and executive control attentional functions. Compared with previous versions, the ANTI-V includes a vigilance task, more reliable auditory alerting signals, non-predictive peripheral orienting cues, and also a neutral no-cue condition allowing the analysis of reorienting costs and orienting benefits. Thus, new evidence to evaluate the influence of sleep deprivation on attentional functioning is provided. Results revealed differences in both tonic and phasic alertness after sleep deprivation. Vigilance performance was deteriorated, while a warning tone was more helpful to increase participants' alertness, resulting in slightly faster RT and, in particular, fewer errors. The reorienting costs of having an invalid spatial cue were reduced after sleep loss. No sleep deprivation effect on the executive control measure was found in this study. Finally, since no control group was used, particular precautions were taken to reduce the influence of potential practice effects.
