How implicitly activated and explicitly acquired knowledge contribute to the effectiveness of retrieval cues

The extralist cued recall task simulates everyday reminding because a memory is encoded on the fly and retrieved later by an unexpected cue. Target words are studied individually, and recall is cued by associatively related words having preexisting forward links to them. In Experiments 1 and 2, forward cue-to-target and backward target-to-cue strengths were varied over an extended range in order to determine how these two sources of strength are related and which source has a greater effect. Forward and backward strengths had additive effects on recall, with forward strength having a consistently larger effect. The PIER2 model accurately predicted these findings, but a plausible generation-recognition version of the model, called PIER.GR, could not. In Experiment 3, forward and backward strengths, level of processing, and study time were varied in order to determine how preexisting lexical knowledge is related to knowledge acquired during the study episode. The main finding indicates that preexisting knowledge and episodic knowledge have additive effects on extralist cued recall. PIER2 can explain these findings because it assumes that these sources of strength contribute independently to recall, whereas the eSAM model cannot explain the findings because it assumes that the sources of strength are multiplicatively related.     

Housing for People with Serious Mental Illness: A Comparison of Values and Research

This article contrasts values associated with the delivery of housing programs for people with serious mental illness with the typical topics pertaining to housing that are studied by researchers. Six values were identified through a search and content analysis of the literature on housing for people with serious mental illness. A second review of the literature was conducted to identify research on housing for this population. A comparison of findings from the two reviews suggested that whereas values concerned with the therapeutic benefits of housing had received considerable research attention, those concerned with a citizenship dimension had received relatively little. The findings are discussed in terms of their implications for the delivery of housing services and for housing research.     

Familiar shapes attract attention in figure-ground displays

We report five experiments that explore the effect of figure-ground factors on attention. We hypothesized that figural cues, such as familiar shape, would draw attention to the figural side in an attentional cuing task using bipartite figure-ground displays. The first two experiments used faces in profile as the familiar shape and found a perceptual advantage for targets presented on the meaningful side of the central contour in detection speed (Experiment 1) and discrimination accuracy (Experiment 2). The third experiment demonstrated the figural advantage in response time (RT) with nine other familiar shapes (including a sea horse, a guitar, a fir tree, etc.), but only when targets appeared in close proximity to the contour. A fourth experiment obtained a figural advantage in a discrimination task with the larger set of familiar shapes. The final experiment ruled out eye movements as a possible confounding factor by replicating the RT advantage for targets on the figural side of face displays when all trials containing eye movements were eliminated. The results are discussed in terms of ecological influences on attention, and are cast within the framework of Yantis and Jonides's hypothesis that attention is exogenously drawn to the onset of new perceptual objects. We argue that the figural side constitutes an "object" whereas the ground side does not, and that figural cues such as shape familiarity are effective in determining which areas represent objects.     

Ways an actualist might be

I discuss Stalnaker’s views on modality. In particular, his views on actualism, anti-essentialism, counterpart theory, and the Barcan formulas.

An experimental approach to detecting dementia in Down syndrome: a paradigm for Alzheimer's disease

Measures developed from animal models of aging may detect dementia of the Alzheimer's type in a population at-risk for Alzheimer's disease (AD). Although, by middle age, individuals with Down syndrome (DS) show an extraordinarily high prevalence of AD-type pathology, their severe idiopathic cognitive deficits tend to confound the clinical diagnosis of AD. The current study was designed to improve detection of AD in DS by using measures of learning and memory derived from animal models of aging. Adults with DS (N=34) were assessed and reassessed (n=19) approximately one year later using stimulus-response (S-R) test methods derived from experimental literature, as well as standardized informant-based tests. Results demonstrated high validity and reliability of select tests. The implication of early symptom detection in a population at-risk for AD-type dementia was discussed in terms of potential brain regions of interest.     

Visual and Auditory Message Framing Effects on Tobacco Smoking1

Persuasive health messages can be framed to emphasize the benefits of adopting a health behavior (gains) or the risks of not adopting it (losses). This study examined the effects of message framing on beliefs, attitudes, and behaviors relevant to cigarette smoking. In video presentations about tobacco smoking, visual images and auditory voiceover content were framed either as gains or losses, yielding 4 message conditions. Undergraduates (N= 437) attending a public university in New England were assigned randomly to view one of these messages. Gain‐framed messages about smoking in visual and auditory modalities shifted smoking‐related beliefs, attitudes, and behaviors in the direction of avoidance and cessation. Health‐communication experts, when promoting prevention behaviors like smoking avoidance or cessation, may wish to diverge from the tradition of using loss‐framed messages and fear appeals in this domain, and instead consider using gain‐framed appeals that present the advantages of not smoking.     

Gender Differences in Work-Family Guilt in Parents of Young Children

The transition to parenthood is a watershed moment for most parents, introducing the possibility of intra-individual and interpersonal growth or decline. Given the increasing number of dual-earner couples in the United States, new parents’ attitudes towards employment (as well as the ways in which they balance employment and personal demands) may have an impact on their overall well-being. Based on anecdotal accounts, guilt about the conflict between employment and family (termed work-family guilt) appears particularly pervasive among U.S. mothers of young children; specifically, mothers, but not fathers, express high levels of a subtype of work-family guilt, that pertains to the negative impact their work has on their families (termed work-interfering-with-family guilt). However, little research within psychology has explicitly examined this phenomenon, and to our knowledge, no quantitative study has investigated gender differences in work-family guilt among U.S. parents of young children. In a cross-sectional, correlational study involving 255 parents of toddlers from the greater Southern California area, we coded parents’ narrative responses to a series of open-ended questions regarding employment and family for the presence of work-family guilt and work-interfering-with-family guilt (in the form of guilt about the negative impact of employment on children). Mothers had significantly higher work-family guilt and work-interfering-with-family guilt relative to fathers. We discuss our findings in terms of theory on gender roles, as well as the questions they generate for future areas of investigation.     

Deconstructing the Time-Out: What Do Mothers Understand About a Common Disciplinary Procedure?

Time-out (TO) is one of the most common and effective disciplinary tactics used to address problem behavior; however, parents rate TO as one of the least useful behavior modification techniques. This may be due to a discrepancy between empirically supported TO procedures and how mothers are actually conducting TO. Fifty-five mothers were asked to define TO, provide information on how they conduct TO, and identify errors in TO procedures. Results indicate that maternal knowledge and implementation of TO differs considerably from the empirical ideal, potentially impacting the utility and frequency of TO usage in the home to address child problem behaviors.
