God’s Faithfulness and Dementia: Christian Theology in Context

Christian theology concerns the practical, contextual realities of life in the church and the world. What does this mean for a person with dementia? While much dementia care focuses on deficits, this article promotes a different starting point: God’s faithfulness rather than our forgetfulness. Using case studies from residential aged care, opportunities for meaningful pastoral care are explored, inviting us to see in the person with dementia a deep connection with ourselves. Drawn from a theological understanding of God as three persons—Father, Son and Holy Spirit—“person-centered care” invites us into relationships of mutuality and reciprocity not dependent on words. Pastoral care of families is manifest through personal relationships where all aspects of dementia, including death and dying, can be discussed openly. Grounded in God’s faithfulness, the first and final word is love. Hope lies in the belief that we have already been found. We are blessed by the grace of God, called into community where the insightful and the forgetful flourish together.     

A structural examination of the Learning Experiences Questionnaire

The underlying factor structure of the Learning Experiences Questionnaire (LEQ; Schaub, 2004) was examined using data from 742 male and female college-age respondents. The LEQ items reflect a variety of learning experiences (generated based on Bandura's (1986, 1997) four sources of self-efficacy perceptions) that might occur in each of Holland's (1997) six RIASEC domains. The LEQ was expected to have a multi-dimensional factor structure, with dimensions representing both RIASEC context and learning experience type. A multi-trait multi-method framework was used to compare the relative fits of a series of models with different theoretically implied dimensionalities, estimated using confirmatory factor analysis. Results supported the proposed multi-dimensional structure. Results of follow-up tests of measurement invariance for men and women revealed that configural and partial factorial invariance held, implying that the LEQ measure functions similarly for men and women.     

Gentzen Calculi for the Existence Predicate

We introduce Gentzen calculi for intuitionistic logic extended with an existence predicate. Such a logic was first introduced by Dana Scott, who provided a proof system for it in Hilbert style. We prove that the Gentzen calculus has cut elimination in so far that all cuts can be restricted to very simple ones. Applications of this logic to Skolemization, truth value logics and linear frames are also discussed.     

Feasibility of a Telephone Intervention for HIV Patients and Their Informal Caregivers

Objectives: To assess the feasibility of a telephone intervention for HIV-positive patients and their caregivers. Methods: HIV-positive participants, some co-enrolled with their informal caregiver, enrolled in this randomized study. Intervention-arm participants (124 patients and 76 caregivers; dyads assigned to same arm) received up to 12 scheduled calls from an interventionist over 6 months. Results: An average of 7.6 (SD = 3.0) calls to each participant was completed; 66.5% received at least 6 calls; 43.0% received more than 75% of the intervention (defined as ‘study adherent’). Having a higher T-cell count was associated with call adherence (p = .014); cocaine use was associated with reduced call adherence for both patients (p = .019) and caregivers (p = .083). Common telephone themes included problems with mood, relationships, finances, housing, and work; interventions (e.g., referral for mental health care) were initiated in response to these. Participant satisfaction was high, and many reported benefits from the intervention. Conclusions: Using a telephone intervention with HIV-positive patients and their caregivers is a feasible and potentially beneficial intervention.     

Attentional and anatomical considerations for the representation of simple stimuli in visual short-term memory: evidence from human electrophysiology

Observers encoded the spatial arrangement of two or three horizontal line segments relative to a square frame presented for 150 ms either in left or right visual field and either above or below the horizontal midline. The target pattern was selected on the basis of colour (red vs. green) from an equivalent distractor pattern in the opposite left–right visual hemifield. After a retention interval of 450 or 650 ms a test pattern was presented at fixation. The task was to decide whether the test was the same as the encoded pattern or different. Selection of the to-be-memorised pattern produced an N2pc response that was not influenced by the number of line segments nor by the length of the retention interval, but that was smaller in amplitude for patterns presented in the upper visual field compared with patterns presented in the lower visual field. A sustained posterior contralateral negativity (SPCN) followed the N2pc. The SPCN was larger for patterns with three line segments than for two, was larger for patterns encoded from lower visual field than from upper visual field, and returned to baseline sooner for the shorter retention interval than for the longer interval. These results, and others, provide an interesting and complex pattern of similarities and differences between the N2pc and SPCN, consistent with the view that N2pc reflects mechanisms of attentional selection whereas the SPCN reflects maintenance in visual short-term memory.     

Subject Competence and Minimization of the Bystander Effect

While performing a drawing task, either alone or in the presence of an observer, high- and low-competent subjects heard a workman fall off a ladder in an adjoining room. As expected, high-competent subjects (Registered Nurses) who witnessed the emergency with another bystander helped as frequently as subjects who witnessed the emergency alone; low-competent subjects (general students) evidenced the familiar bystander effect. Responses to the post-emergency questionnaire indicated that at the time of the emergency both high- and low-competent subjects felt strongly that they should do something to help the workman. The minimization of the bystander effect for the high-competent subjects was mediated by confidence in their ability to help the workman and in knowing what steps to take to help. Discussion focused on the role of subject competency in bystander intervention, effective debriefing, and the subjects' positive reactions to participating in a bystander experiment.     

Involuntary attention and identification accuracy

Using the spatial cuing paradigm, Prinzmetal, McCool, and Park (2005) made the distinction between voluntary and involuntary attention. They claimed that although accuracy was affected by an informative spatial cue (which controls voluntary attention), it was not affected by a noninformative cue (which controls involuntary attention). We reevaluate two reports that assert that noninformative spatial cues affect accuracy. Dufour (1999) reported that a noninformative auditory cue enhanced visual identification in a conjunction search task. Klein and Dick (2002) reported that, in an RSVP task with visual cues, the cue also enhanced accuracy at short stimulus onset asynchronies. We found that Dufour's results were due to overt orienting (eye movements) rather than to covert attention. The results of Klein and Dick were due either to location uncertainty or to a confounding of the order of stimulus presentation and condition.     

Remembering a nuclear accident in Japan: did it trigger flashbulb memories?

Flashbulb memories are vivid memories of the details surrounding the discovery of an emotional event. We investigated whether the nuclear accident that occurred in Japan in 1999 produced flashbulb memories among people who lived near the accident site. A questionnaire was distributed twice (approximately 3 weeks after the accident and 1 year later) to (1) the residents of the communities surrounding the accident site, (2) the students at a university near the accident site, and (3) the students at two universities far away from the accident site. Flashbulb memory holders were defined as those individuals who showed consistent memories between test and retest. The results indicated that only a small percentage of participants formed flashbulb memories. Further, no age-related decline was found. Flashbulb memories were distinguished by perfect or near perfect scores on four attributes: source, place, activity, and people. The results also indicated that the ratings on emotional reactions, personal consequentiality, and surprise did not differentiate between the flashbulb and non-flashbulb memory holders. In contrast, the flashbulb memory holders reported rehearsing more than the non-flashbulb memory holders. These results supported the notion that flashbulb memories are formed through rehearsal rather than at encoding. However, it is also possible that rehearsal was a result of the flashbulb memory.
