Systems change reborn: rethinking our theories, methods, and efforts in human services reform and community-based change

This article introduces the reader to this special issue on Systems Change and highlights six lessons learned about theory, methods, and interventions for systems change that emerged across the included articles. The value of a systems approach to systems change is examined, including the need for frameworks, methods, and change activities that attend to the characteristics of systems.

Maternal sensitivity assessed during the strange situation procedure predicts child's attachment quality and reunion behaviors

The 72-item version maternal behavior Q-set (MBQS; Pederson & Moran, 1995) was used to assess maternal behaviors (N = 74) during the Strange Situation Procedure. Results indicated that the MBQS scores significantly differentiated infant attachment categories and were significantly associated with a series of infants’ reunion behaviors.     

An improved algorithm for automatic detection of saccades in eye movement data and for calculating saccade parameters

This analysis of time series of eye movements is a saccade-detection algorithm that is based on an earlier algorithm. It achieves substantial improvements by using an adaptive-threshold model instead of fixed thresholds and using the eye-movement acceleration signal. This has four advantages: (1) Adaptive thresholds are calculated automatically from the preceding acceleration data for detecting the beginning of a saccade, and thresholds are modified during the saccade. (2) The monotonicity of the position signal during the saccade, together with the acceleration with respect to the thresholds, is used to reliably determine the end of the saccade. (3) This allows differentiation between saccades following the main-sequence and non-main-sequence saccades. (4) Artifacts of various kinds can be detected and eliminated. The algorithm is demonstrated by applying it to human eye movement data (obtained by EOG) recorded during driving a car. A second demonstration of the algorithm detects microsleep episodes in eye movement data.     

Developmental changes of sleep spindles and their impact on sleep‐dependent memory consolidation and general cognitive abilities: A longitudinal approach

Sleep spindles are related to sleep‐dependent memory consolidation and general cognitive abilities. However, they undergo drastic maturational changes during adolescence. Here we used a longitudinal approach (across 7 years) to explore whether developmental changes in sleep spindle density can explain individual differences in sleep‐dependent memory consolidation and general cognitive abilities. Ambulatory polysomnography was recorded during four nights in 34 healthy subjects (24 female) with two nights (baseline and experimental) at initial recording (age range 8–11 years) and two nights at follow‐up recording (age range 14–18 years). For declarative learning, participants encoded word pairs with a subsequent recall before and after sleep. General cognitive abilities were measured by the Wechsler Intelligence Scale. Higher slow (11–13 Hz) than fast (13–15 Hz) spindle density at frontal, central, and parietal sites during initial recordings, followed by a shift to higher fast than slow spindle density at central and parietal sites during follow‐up recordings, suggest that mature spindle topography develops throughout adolescence. Fast spindle density increases from baseline to experimental night were positively related to sleep‐dependent memory consolidation. In addition, we found that the development of fast spindles predicted the improvement in memory consolidation across the two longitudinal measurements, a finding that underlines a crucial role for mature fast spindles for sleep‐dependent memory consolidation. Furthermore, slow spindle changes across adolescence were related to general cognitive abilities, a relationship that could indicate the maturation of frontal networks relevant for efficient cognitive processing.

How known constructions influence the acquisition of other constructions: the german passive and future constructions

This article suggests evidence for and reasons why prior acquisition may either facilitate or inhibit acquisition of a new construction. It investigates acquisition of the German passive and future constructions which contain a lexical verb with either the auxiliary sein "to be" or werden "to become", and are related through these to potential supporting constructions. We predicted that a supported construction should be acquired earlier, faster, and unusually rapidly. An inhibited construction should show an extended depressed usage. We analyzed a dense corpus of a German boy between 2;0 and 5;0. He acquired the sein- before the werden-passive. The former was supported by his prior acquisition of the sein copula, whereas the werden-passive itself supported one werden copula construction. He acquired the werden-future extremely slowly due to the hindrance of a semantically identical construction. These results fit with an emergentist approach in which apparently "sudden" acquisition is still due to gradual learning mechanisms.     

Working Pasteur's Quadrant: harnessing science and action for community change

Community psychology in general and the field of prevention in particular has unquestioningly accepted the assumption that the research process should proceed in a linear fashion from a search for basic knowledge to application in the community context. This ignores the compelling insight offered by Stokes (1997) that the drive for new knowledge and the pursuit of application can be combined in a single effort. If research in community psychology pursues the drive for application without an equal commitment to the development of knowledge about underlying community processes of social cooperation and change, it will become a field less capable of innovative and enduring contributions to community well-being and effectiveness. Opportunities abound in community psychology for the simultaneous pursuit of new knowledge and more effective practice. We offer the example of a community leadership development program to promote collective efficacy as a case in point.     

Repeating the Errors of Our Parents? Family‐of‐Origin Spouse Violence and Observed Conflict Management in Engaged Couples*

Based on a developmental social learning analysis, it was hypothesized that observing parental violence predisposes partners to difficulties in managing couple conflict. Seventy-one engaged couples were assessed on their observation of parental violence in their family of origin. All couples were videotaped discussing two areas of current relationship conflict, and their cognitions during the interactions were assessed using a video-mediated recall procedure. Couples in which the male partner reported observing parental violence (male-exposed couples) showed more negative affect and communication during conflict discussions than couples in which neither partner reported observing parental violence (unexposed couples). Couples in which only the female partner reported observing parental violence (female-exposed couples) did not differ from unexposed couples in their affect or behavior. Female-exposed couples reported more negative cognitions than unexposed couples, but male-exposed couples did not differ from unexposed couples in their reported cognitions.     

Characterizing sentence intonation in a right hemisphere-damaged population

Current production studies present a mixed view of right hemisphere-damaged (RHD) patients' ability to produce normal sentence intonation. The present study characterized the sentence intonation of RHD patients, focusing on a greater number of acoustic parameters than past works, and relying on more naturally elicited speech samples through use of a story completion task. Eight RHD speakers and seven nonneurological control subjects produced declarative and imperative sentences as well as yes-no and wh-questions. Slope of F0 change, linearity of pitch contour, and variance of F0 points were calculated for each utterance as a whole, as well as for the preterminal and the terminal contour separately. RHD contours were less linear and flatter in F0 decline than normal controls for the declarative sentences. The patients' yes-no questions also differed from normal productions, displaying smaller F0 dispersion around a mean F0. Preterminal range values were more restricted for patients' utterances of yes-no questions, while terminal properties between groups differed for three of the four sentence types examined. The present results suggest some disturbance in the patients' ability to manipulate fundamental frequency across sentential domains. These data are discussed in terms of current theories of a general dysprosody in RHD patients.     

An edited translation of the first dissertation in experimental psychology by Max Friedrich at Leipzig University in Germany

Summary The present paper presents an edited translation of the first doctoral thesis in experimental psychology, completed by Max Friedrich at Leipzig University during the Winter Semester of 1879–80. The official degree was awarded in 1880 and the full text was published in the first issue of Wundt's journal Philosophische Studien (Philosophical Studies). In addition to a translation of the original text, the author provides a critical analysis of the methodology and results of Friedrich within the context of modern psychophysics.Support for this project came from grants from the Scholarship Support Fund of The Pennsylvania State University. Appreciation is extended to Doris Grab who ably assisted in the translation process and to Wolfgang Bringmann who was instrumental in this project becoming a reality from its conception in 1975
