Working memory as internal attention: Toward an integrative account of internal and external selection processes

Working memory (WM) and attention have been studied as separate cognitive constructs, although it has long been acknowledged that attention plays an important role in controlling the activation, maintenance, and manipulation of representations in WM. WM has, conversely, been thought of as a means of maintaining representations to voluntarily guide perceptual selective attention. It has more recently been observed, however, that the contents of WM can capture visual attention, even when such internally maintained representations are irrelevant, and often disruptive, to the immediate external task. Thus, the precise relationship between WM and attention remains unclear, but it appears that they may bidirectionally impact one another, whether or not internal representations are consistent with the external perceptual goals. This reciprocal relationship seems, further, to be constrained by limited cognitive resources to handle demands in either maintenance or selection. We propose here that the close relationship between WM and attention may be best described as a give-and-take interdependence between attention directed toward either actively maintained internal representations (traditionally considered WM) or external perceptual stimuli (traditionally considered selective attention), underpinned by their shared reliance on a common cognitive resource. Put simply, we argue that WM and attention should no longer be considered as separate systems or concepts, but as competing and influencing one another because they rely on the same limited resource. This framework can offer an explanation for the capture of visual attention by irrelevant WM contents, as well as a straightforward account of the underspecified relationship between WM and attention.     

The wane of childhood amnesia for autobiographical and public event memories

We modified Bruce, Dolan, and Phillips-Grant's (2000) threshold procedure for determining the wane of childhood amnesia. In two experiments, undergraduates labelled childhood events (e.g., your first permanent tooth came in) as know or recollect memories and estimated their age at the event's occurrence. In both studies the estimated transition from mostly know memories to mostly recollect memories was roughly 4.7 years. This transition estimate was replicated in a sample of adults (ages 24-65 years) with both Bruce et al.'s event-generation task and the Experiment 1a questionnaire. By contrast, in two experiments a transition estimate of roughly 6 years was found for undergraduates' memories of public events (e.g., the Challenger explosion). The wane of childhood amnesia appears to occur around 4.7 years.     

The Capstone Experience for the Religious Studies Major

The purpose of this essay is to offer a survey of religious studies capstones from twenty‐nine U.S. colleges and universities, to identify the most common frustrations about the capstone, and to observe how departments resolve such frustrations. I conclude that the most successful capstones – in terms of students' performance and faculty satisfaction – are those that are carefully linked to their department's major curriculum, pedagogies, and staffing, that set out to achieve a reasonable set of objectives, and that are aligned with their institutional mission, culture, and expectations for assessment. Yet, I argue that it is becoming increasingly difficult to design our capstone experiences according to the above principles because of the proliferation of departmental and institutional pressures we presently face. Finally, I offer some guidelines by which we might devise or revise our capstones to alleviate some of the most common pressures.     

Longitudinal Effects of Reading Intervention on Below Grade Level,Preadolescent, Title I Students

Some claim that good and poor readers continue their trajectories despite intervention. This quasi-experimental study examined whether the READ 180 program helps general education, below-grade-level, Title I preadolescent readers improve. Participants included 82 students, grades 4–8, in public Title I elementary and middle schools. Results showed that below grade-level readers improved after intervention and attained grade-level status. Differences remained between participants and their nonintervention peers during follow-up testing. However, when examining growth trajectories, a reversal in performance between the two groups was manifested. The below-grade-level students’ mean growth between years 1 and 2 after intervention was actually greater than that of their on-grade-level peers with no intervention. The performance trajectory narrowed over time after successful intervention.     

Consultation-based Academic Interventions for Children with ADHD: Effects on Reading and Mathematics Achievement

The purpose of this investigation was to evaluate the relative efficacy of two consultation-based models for designing academic interventions to enhance the educational functioning of children with attention-deficit/hyperactivity disorder (ADHD). Children (N=167) meeting DSM-IV criteria for ADHD were randomly assigned to one of two consultation groups: Individualized Academic Intervention (IAI; interventions designed using a data-based decision-making model that involved ongoing feedback to teachers) and Generic Academic Intervention (GAI; interventions designed based on consultant-teacher collaboration, representing "consultation as usual"). Teachers implemented academic interventions over 15 months. Academic outcomes (e.g., standardized achievement test, and teacher ratings of academic skills) were assessed on four occasions (baseline, 3 months, 12 months, 15 months). Hierarchical linear modeling analyses indicated significant positive growth for 8 of the 14 dependent variables; however, trajectories did not differ significantly across consultation groups. Interventions in the IAI group were delivered with significantly greater integrity; however, groups did not differ with respect to teacher ratings of treatment acceptability. The results of this study provide partial support for the effectiveness of consultation-based academic interventions in enhancing educational functioning in children with ADHD; however, the relative advantages of an individualized model over "consultation as usual" have yet to be established.     

The relationship between the Wechsler Memory Scale—Revised (WMS-R) Attention index and putative measures of Attention

Although the Wechsler Memory Scale—Revised (WMS-R; Wechsler, 1987) is one of the more frequently used measures of memory and attention, its Attention/Concentration Index (ACI) has been minimally researched. If the ACI is to be used as a measure of attention, the need exists to determine if it is related to other measures theoretically argued to be sensitive to attention deficits. The present study evaluated the relationship between the WMS-R ACI and other putative measures of attention by comparing individuals labeled as Attention Impaired [ACI at least 15 points < General Memory Index (GMI)] versus those labeled as Memory Impaired (GMI at least 15 points < ACI). Contrary to expectations, the Attention Impaired group scored equal to the Memory Impaired group on all measures theorized to be sensitive to attention deficits (Trails A and B time, Trails B errors, Rey AVLT interference list), except for statistically weaker performance on Trails A errors. In contrast but as expected, the Memory Impaired group scored statistically worse on all memory tests (Rey AVLT, all TPT variables). The groups also did not differ on tests argued not to be differentially affected by either attention or memory (WAIS-R FIQ, Category Test). It is concluded that the WMS-R Attention Index is not related to deficits on other measures sensitive to attention, further emphasizing the need to identify more clearly specific attention constructs.     

Religion and the Recovery of Addicted Women

Personal interviews were conducted with 102 African-American and Anglo-American women in Texas coastal communities to determine the involvement of religious organizations in women's initiation and maintenance of recovery from drug addiction, the extent of women's help-seeking for recovery, and women's spiritual needs. Means, frequencies, chi squares, Pearson's correlations, and one-way ANOVAs were used to describe the data. Religious organizations helped about one-third of the women to begin or stay in recovery, primarily through counseling or ministering to spiritual needs. Only one-fourth of the women had sought help from churches. The predominant spiritual needs were forgiveness, love, and understanding. Implications for research and outreach are given.     

Overoptimism about future knowledge: Early arrogance?

Abstract

Three studies explored whether young children (5–7 years) have more optimistic views of their future knowledge than older children (8–12 years) and adults. In Study 1, younger children were more likely than older children and adults to expect greater knowledge in both young and mature protagonists. Both groups of children saw knowledge rising at a faster rate into adulthood than adult participants did. All ages judged moral knowledge as much easier to acquire than other types of knowledge, such as artifacts. In Study 2, all children saw their own future knowledge in especially optimistic terms in comparison to ratings by adults, and the older children exhibited a self-enhancement bias. Study 3 found an overall preference for the acquisition of positively valenced future knowledge, particularly for the 8- to 12-year olds and in the domain of morality, suggesting pragmatic underpinnings for these judgments.     

Examining the differences in career thoughts of women in three low socioeconomic status groups

The authors examined differences in career thoughts of 3 groups of women from low socioeconomic status backgrounds. The 3 groups were composed of women who were not seeking employment, women attempting to obtain General Educational Development (GED) certification prior to seeking employment, and women with disabilities who were participating in readiness‐to‐work programs. Results indicated that there were significant differences in participants' career thoughts. Specifically, career thoughts of women who were not seeking employment were significantly less dysfunctional than were the career thoughts of the women who were pursuing their GED certification and those of the women with disabilities who were participating in a job‐readiness training program. The impact of negative career thoughts is discussed.
