Implementing computerized technology: an organizational analysis

Why do some organizations succeed and others fail in implementing the innovations they adopt? To begin to answer this question, the authors studied the implementation of manufacturing resource planning, an advanced computerized manufacturing technology, in 39 manufacturing plants (number of individual respondents = 1,219). The results of the plant-level analyses suggest that financial resource availability and management support for technology implementation engender high-quality implementation policies and practices and a strong climate for implementation, which in turn foster implementation effectiveness--that is, consistent and skilled technology use. Further research is needed to replicate and extend the findings.     

Self-concept correlates of the personality disorders

This study investigated the extent to which the DSM personality disorder dimensions are associated with discrete patterns of self-concept. Participants were 366 men and women who were receiving mental health services and who completed the Wisconsin Personality Disorders Inventory to assess the personality disorders and Benjamin's INTREX questionnaire to describe their "typical" self-concepts. Although there was some overlap between categories, most were associated with fairly distinct patterns of self-concept. The disorders also clustered together in meaningful ways along the major axes of Benjamin's interpersonal model of the self-concept.     

A construct validation study of the Response Styles Questionnaire Rumination Scale in participants with a recent-onset major depressive episode

This study examined the construct validity and clinical utility of S. Nolen-Hoeksema's (1991) Response Styles Questionnaire (RSQ) Rumination scale. Eighty-eight participants with recent-onset major depressive episodes were assessed and followed for 6 months, using semistructured interviews and self-report inventories. The RSQ Rumination scale exhibited poor 6-month stability and appeared to be closely linked to participants' clinical status-mood state. The scale was significantly correlated with conceptually related constructs such as emotion-focused coping, negative affectivity-temperament, and self-criticism. However, baseline negative temperament and self-criticism predicted key aspects of the 6-month course and outcome of major depressive episodes, whereas baseline rumination did not. Finally, rumination appeared to be closely associated with the severity of the depressive episode, rather than defining a distinct clinical subtype.     

Eccentric head positions bias random generation of leftward and rightward handle-bar rotations

We explored the effects of eccentric head positions on rapid rotations of a handle-bar in a modified randomization task. Subjects had to generate a random sequence of leftward and rightward handle-bar rotations; each pre-selected rotation was produced in response to a visual signal as rapidly as possible. Eccentric head positions induced a bias in that handle-bar rotations in the direction of the eccentric head position were chosen more frequently than handle-bar rotations in the opposite direction. This is consistent with previous evidence on a spatial coupling. In contrast to response selection, response initiation was not affected by eccentric head positions. The kinematic characteristics, however, differed: rotations in the direction of the eccentric head position were of larger amplitude and longer duration than rotations in the opposite direction. This difference may have been secondary to a difference in the start positions of the handle-bar, which were shifted in the direction opposite to the eccentric head position.     

Inhibition of return in static but not necessarily in dynamic search

If and when search involves the serial inspection of items by covert or overt attention, its efficiency would be enhanced by a mechanism that would discourage reinspections of items or regions of the display that had already been examined. Klein (1988, 2000; Klein & Dukewich, 2006) proposed that inhibition of return (IOR) might be such a mechanism. The present experiments explored this proposal by combining a dynamic search task (Horowitz & Wolfe, 1998, 2003) with a probe-detection task. IOR was observed when search was most efficient (static and slower dynamic search). IOR was not observed when search performance was less efficient (fast dynamic search).These findings are consistent with the “foraging facilitator” proposal of IOR and are unpredicted by theories of search that assume parallel accumulation of information across the array (plus noise) as a general explanation for the effect of set size upon search performance.     

The unanticipated resilience of trait self-knowledge in the face of neural damage

This paper explores the question of what the self is by reviewing research conducted with both normal and neuropsychological participants. Findings converge on the idea that the self may be more complex and differentiated than some previous treatments of the topic have suggested. Although some aspects of self-knowledge such as episodic recollection may be compromised in individuals, other aspects-for instance, semantic trait summaries-appear largely intact. Taken together, these findings support the idea that the self is not a single, unified entity. Rather, it is a set of interrelated, functionally independent systems. In the process of reviewing neuropsychological findings, an unexpected result emerges: trait self-knowledge appears unusually robust with respect to neural and cognitive damage that render other aspects of self-knowledge dysfunctional in varying degrees.     

Maternal personality influences the relationship between maternal reports and laboratory measures of child temperament

Previous research has indicated that agreement between maternal reports of child temperament and laboratory measures is modest; however, it is unclear whether maternal characteristics influence convergence between methods. We examined whether mothers' personality influenced agreement between maternal reports and observational measures of child traits. A total of 64 mothers and children participated in this study. Maternal negative emotionality (NE) moderated the relationship between maternal reports and laboratory measures of child temperament: Greater convergence was found between maternal ratings of children's negative emotional traits and laboratory measures for mothers with higher NE than mothers with lower NE. Findings are consistent with the possibility that mothers' own traits influence the extent to which they successfully encode and/or report on analogous child behaviors.     

The effect of peer comparison information in the context of expert recommendations on risk perceptions and subsequent behavior

The present study seeks to understand how social comparison information may be used to provide individuals with information about their level of risk and to promote health behavior. The effect of peer comparison information, presented alone or in the context of expert recommendations, was examined across two studies using distinct experimental manipulations. Study 1 showed that regardless of whether expert standards were available or not, participants who were provided with inflated estimates of peer flossing behavior demonstrated increased behavioral intentions and increased flossing behavior measured 3 months later. This pattern was replicated in Study 2 with effects on attitudes toward flossing and intentions to floss. These findings add to a growing literature identifying comparative feedback as distinct from objective information and are discussed in terms of implications for health promotion and risk communication.

The effects of scene inversion on change blindness

In two experiments, participants searched for a difference between two views of a scene. In Experiment 1, the authors extended the change-blindness findings from previous work by R. A. Rensink, J. K. O'Regan, and J. J. Clark (1997), which used an experimenter-induced global transient, to a less artificial situation in which participants searched for a difference in a pair of photographic images presented simultaneously. To examine the idea that meaning-driven endogenous orienting was responsible for the previously observed advantage for changes in center-of-interest items, the authors inverted half of the image pairs. The advantage for center-of-interest items was replicated with upright displays, but it was completely eliminated by inversion, strongly supporting the role of meaning-driven endogenous orienting in this task. With flickering displays (Experiment 2), the center-of-interest effect was completely unaffected by inversion. The authors suggest that when change blindness is induced via flicker, scene modifications are typically found by stimulus-driven rather than by meaning-driven processes.
