Do intersections serve as basic features in visual search?

The status of 'intersection' as a basic feature in visual search tasks has been controversial. Under some circumstances, a target possessing this attribute (eg a plus) 'pops out' of a display of distractors that lack the attribute (eg Ls). However, those cases may be artifacts of other features such as relative size or number of line terminators. We report two sets of experiments with stimuli intended to control for these factors. Search for the presence or absence of intersections is very inefficient with these stimuli. The results suggest that intersection should not be included among the list of salient features that support efficient search through visual displays.     

Searching night and day: a dissociation of effects of circadian phase and time awake on visual selective attention and vigilance

How does sleepiness affect selective attention? We studied the effect of circadian phase and time awake on visual search. The generalized-cognitive-slowing hypothesis predicts that search rate will be slower, feature guidance less effective, and response time (RT) lengthened when observers are sleepy. Observers performed spatial-configuration (finding a 5 among 2s) and conjunction (finding red vertical among red horizontal and green vertical) search tasks during 38 hr of wakefulness under constant conditions. Adverse circadian phases and elapsed time awake did lead to increased RT (corrected for errors). However, contrary to the hypothesis, search rates (indexed by RT x Set Size slopes) were constant across the protocol. This was true for conjunction as well as for spatial-configuration search, indicating that feature guidance was also insensitive to sleepiness. The locus of sleepiness effects on search is probably downstream from the bottleneck of attentional selection. Observers did trade accuracy for speed when sleepy. This implicates decision-stage impairments.     

Guided Search 2.0 A revised model of visual search

An important component of routine visual behavior is the ability to find one item in a visual world filled with other, distracting items. This ability to performvisual search has been the subject of a large body of research in the past 15 years. This paper reviews the visual search literature and presents a model of human search behavior. Built upon the work of Neisser, Treisman, Julesz, and others, the model distinguishes between a preattentive, massively parallel stage that processes information about basic visual features (color, motion, various depth cues, etc.) across large portions of the visual field and a subsequent limited-capacity stage that performs other, more complex operations (e.g., face recognition, reading, object identification) over a limited portion of the visual field. The spatial deployment of the limited-capacity process is under attentional control. The heart of the guided search model is the idea that attentional deployment of limited resources isguided by the output of the earlier parallel processes. Guided Search 2.0 (GS2) is a revision of the model in which virtually all aspects of the model have been made more explicit and/or revised in light of new data. The paper is organized into four parts: Part 1 presents the model and the details of its computer simulation. Part 2 reviews the visual search literature on preattentive processing of basic features and shows how the GS2 simulation reproduces those results. Part 3 reviews the literature on the attentional deployment of limited-capacity processes in conjunction and serial searches and shows how the simulation handles those conditions. Finally, Part 4 deals with shortcomings of the model and unresolved issues.     

Tardive dyskinesia and perceptual dysfunction

There is equivocal evidence for a relationship between neuroleptic-induced tardive dyskinesia and central nervous system (CNS) dysfunction. Using the Bender-Gestalt test as the dependent measure, we hypothesized that a group of chronic schizophrenic patients with tardive dyskinesia would show more perceptual dysfunction than those without. Our results supported this hypothesis. CNS dysfunction is discussed in terms of a possible predisposition to tardive dyskinesia.     

Romantic relationship quality during the COVID-19 pandemic: The longitudinal associations with relationship loneliness and depression

The COVID-19 pandemic created significant strain on both mental health and romantic relationships. Therefore, we examined longitudinal associations between romantic relationship quality, relationship loneliness, and depressive symptoms over 6 months of the COVID-19 pandemic. We surveyed 122 couples (n = 244 individuals) in approximately May, September, and November 2020. Using a dyadic mediation model, findings indicated that relationship quality at Time 1 was positively associated with depression at Time 3 for men, but not for women. A significant indirect effect of relationship quality on depression via relationship loneliness at Time 2 was found for both men and women. Self-mastery, or feeling in control of one's life circumstances, was an important covariate of women's depressive symptoms. Overall, these findings highlight relationship loneliness as particularly salient for mental health and demonstrate the importance of high-quality relationships for promoting well-being during stressful events, such as global pandemics.     

Are Christians Theologically Committed to a Rejection of the Principle of Alternative Possibilities?

Many philosophers think that free will requires alternative possibilities. Other philosophers deny this. There are plenty of philosophical arguments on both sides of this debate, but here I want to highlight various theological pressures that might push Christians into rejecting the principle of alternative possibilities. In this paper, I explore six cases that might push Christians in that direction: the case of divine foreknowledge, the case of prophecy, the case of the blessed in heaven, the case of Christ's human freedom, the case of Mary's fiat in light of her immaculate conception, and the case of prayers for the past. As I will argue, in each of these cases, given certain other standard theological commitments, it seems that Christians are pushed to admit that the agent in question does indeed act freely but also that he or she did not possess alternative possibilities at the moment of decision.     

Race,Religion, and Black Lives Matter: Assessing the Association between Sermon Content and Racial Justice Attitudes and Behaviors

We use the 2020/2021 National Politics Study to examine two central questions: 1. How do religious beliefs and clergy sermons about race associate with support for Black Lives Matter (BLM) and racial justice work? And 2. Is the relationship between religion and BLM-related attitudes and activism similar or different across race groups? We found the following: In the months following the summer of 2020 protests in response to George Floyd's murder, African, Hispanic, and White American worship goers who heard sermons about race and policing were more likely than were their co-ethnics to approve of BLM and to engage in racial justice work. Identifying with the religious left and believing that social justice is a core part of one's religaious beliefs is also associated with these groups approving of BLM and engaging in racial justice work. That said, race matters. These forms of religion tend to maintain stronger relationships with White BLM-related attitudes and activism than they do for African Americans and Hispanics.     

Reflections on the process of psychotherapeutic change as applied to medical situations

This article takes the basic ideas on the process of changing implicit knowledge put forward in this special issue, and extends them beyond psychotherapy to include other therapeutic relationships that occur in medicine. One vignette, from an encounter between a medical student and a dying patient, illustrates how a “moment of meeting” changes the student as well as the patient. The second shows how therapeutic interventions for new mothers with their newborn infants involve “moments of meeting” that alter the mother's implicit knowledge of her baby and of herself as a mother. © 1998 Michigan Association for Infant Mental Health     

Religious Requirement: The case for Roman Catholic schools in the 1940s and Muslim schools in the 1990s

This article sets out the four principles which underlay Catholic schooling in the 1940s. Similar principles were expressed by Muslim leaders in the 1990s. The origins of Catholic schools in the 19th century are described, as is the 1870 Act which led to a great increase in their number. Twentieth-century Catholic writers set out the rights and duties of parents and the obligation of the state to fund Catholic schools. The stance of the church in the 1940s is examined in detail. Some characteristics of Islam are then described. Religious observance brings conflict for children attending maintained schools. Parents may campaign for change in these schools, or opt for independent Islamic schools. The conclusions of the Swann Report (1985) regarding separate schooling are set out, followed by the change in government policy after 1997. In conclusion, the article asks whether we may expect an increase in Muslim voluntary aided schools parallel to the earlier increase of Catholic schools.
