Caregiving Attitudes,Personal Loss,and Stress-Related Growth Among Siblings of Adults with Mental Illness

As parents age, well siblings are often asked to assume caregiving responsibilities for their brother or sister with mental illness. However, relatively little is known about how well siblings prioritize sibling caregiving responsibilities with other life demands. We examined well siblings’ attitudes toward self-care and caregiving for their sibling with mental illness (self- and sibling-care) using two cross-sectional samples. The first sample of well siblings (N?=?242) was used to examine the psychometric properties of the self- and sibling-care measure (SSCM), designed to assess the degree to which siblings prioritize their own needs and the needs of their sibling with mental illness. A second sample (N?=?103) was used to determine the relative contribution of self- and sibling-care attitudes in accounting for variation in well siblings’ reports of personal loss and stress-related personal growth. Results support the psychometric validity of the SSCM and suggest that self- and sibling-care attitudes account for greater variance in scores on perceived personal loss and stress-related growth than demographic or caregiving factors. Our findings support the need to address family care responsibilities and resource limitations through recovery-oriented mental health policies, services, and programs.     

Reversible hippocampal lesions disrupt water maze performance during both recent and remote memory tests

Conventional lesion methods have shown that damage to the rodent hippocampus can impair previously acquired spatial memory in tasks such as the water maze. In contrast, work with reversible lesion methods using a different spatial task has found remote memory to be spared. To determine whether the finding of spared remote spatial memory depends on the lesion method, we reversibly inactivated the hippocampus with lidocaine either immediately (0-DAY) or 1 mo (30-DAY) after training in a water maze. For both the 0-DAY and 30-DAY retention tests, rats that received lidocaine infusions exhibited impaired performance. In addition, when the 0-DAY group was retested 2 d later, (when the drug was no longer active), the effect was reversed. That is, rats that had previously received lidocaine performed as well as control rats did. These findings indicate that the rodent hippocampus is important for both recent and remote spatial memory, as assessed in the water maze. What determines whether remote spatial memory is preserved or impaired following disruption of hippocampal function appears to be the type of task used to assess spatial memory, not the method used to disrupt the hippocampus.     

Recency effects in memory,as a function of modality of intervening events

Summary Word lists of fifteen items were presented to eye or to ear, with recall either immediately, or after a visual task, or after an auditory one. Instructions were to recall the last items first. An intervening task using the same modality greatly reduced recall of the last items presented; whereas a visual task did not do so for acoustically presented items. An auditory task reduced visual memory. These results suggest a specific auditory memory for recent events, over-written by subsequent auditory events.This research was supported by the Medical Research Council.

Noise and levels of processing

Three experiments investigated the view that people make more use of relatively surface levels of coding when noise is present, neglecting semantic levels of analysis. In experiment 1 subjects classified words in different ways and then recalled as many as possible. Subjects who received the noise conditions in the order noise-quiet recalled more words than those who received the conditions in the order quiet-noise, but noise failed to interact with the nature of the classification conditions although the usual advantage of the semantic condition over letter-case and rhyme conditions was obtained. Experiment 2 failed to show any effect of noise on physical-name match differences when letter pairs were presented simultaneously. In experiment 3 a delay was introduced between the letters; the noise-quiet subjects were then faster on the physical match than the name match whereas the slower quiet-noise subjects showed the reverse pattern. This could represent an instance of asymmetric transfer from noise to quiet or it could be due to speed per se.Overall, these results argue against a general explanation of noise effects in terms of a passive shift in levels of processing.     

Articulatory suppression and the grouping of successive stimuli

Summary Two experiments required subjects to memorise for immediate recall lists of nine items, presented visually and grouped by threes. As each item followed the previous one in the same spatial location, it must have been temporarily stored until the whole group had arrived. In one experiment the items were digits; grouping could be detected by the fact that recall of the last two items in a group was heavily contingent upon recall of the first item. In the second experiment the items were letters, and some of the lists were made up of meaningful triplets of letters such as UNO. Grouping could be detected by the size of the difference between these lists and the meaningless ones. In each experiment, the extent of grouping was just as great if the subjects were asked to repeat an irrelevant sequence of sounds while memorising; although the recall under both conditions was of course depressed.It appears therefore that the temporary memory, in which the items are held before grouping, is not impaired by articulatory suppression; nor in these conditions could it have been a sensory store. The result is supportive evidence for the existence of an abstract, non-sensory, non-motor, working memory.Both authors are employed, and their research supported, by the Medical Research Council     

Combining attributes in rapid serial visual presentation tasks

A series of three exploratory experiments sought to compare and contrast two broad classes of theory pertaining to visual information pick-up. One theoretical approach, exemplified by Keele and Neill (1978) and by Treisman (1977) emphasizes the relatively passive, parallel development of information codes, with subsequent attentional integration of contiguous codes into a percept. Another theoretical approach, exemplified by Broadbent (1977a) emphasizes the relatively active, sequential, recursive interrogation of a visual display in which the pick-up of each piece of information guides the perceptual system in its quest for more information. The manner in which separable attributes of visual information are picked up and combined was studied by manipulating the roles of different attributes in a rapid serial visual presentation (RSVP) paradigm. Observers were asked to report the name of a letter in a specified target colour; to report the colour of a specified target letter; to report the colour of a specified target numeral embedded in a list of letters; to report the colour of an unspecified numeral embedded in a list of letters; and to perform the latter two tasks without knowing in which of two alternating spatial positions the target might appear. Examination of the patterns of mis-combinations of attributes from target and non-target stimuli yields evidence both for and against each theoretical position, and suggests that the two might better be considered as modes of processing available to the perceptual system, rather than as intrinsic properties of that system.     

Egocentric and allocentric navigation strategies in Williams syndrome and typical development

Recent findings suggest that difficulties on small‐scale visuospatial tasks documented in Williams syndrome (WS) also extend to large‐scale space. In particular, individuals with WS often present with difficulties in allocentric spatial coding (encoding relationships between items within an environment or array). This study examined the effect of atypical spatial processing in WS on large‐scale navigational strategies, using a novel 3D virtual environment. During navigation of recently learnt large‐scale space, typically developing (TD) children predominantly rely on the use of a sequential egocentric strategy (recalling the sequence of left–right body turns throughout a route), but become more able to use an allocentric strategy between 5 and 10 years of age. The navigation strategies spontaneously employed by TD children between 5 and 10 years of age and individuals with WS were analysed. The ability to use an allocentric strategy on trials where spatial relational knowledge was required to find the shortest route was also examined. Results showed that, unlike TD children, during spontaneous navigation the WS group did not predominantly employ a sequential egocentric strategy. Instead, individuals with WS followed the path until the correct environmental landmarks were found, suggesting the use of a time‐consuming and inefficient view‐matching strategy for wayfinding. Individuals with WS also presented with deficits in allocentric spatial coding, demonstrated by difficulties in determining short‐cuts when required and difficulties developing a mental representation of the environment layout. This was found even following extensive experience in an environment, suggesting that – unlike in typical development – experience cannot contribute to the development of spatial relational processing in WS. This atypical presentation of both egocentric and allocentric spatial encoding is discussed in relation to specific difficulties on small‐scale spatial tasks and known atypical cortical development in WS.     

Examining the Presence of Congregational Programs Focused on Violence Against Women

Religious congregations are uniquely poised to provide programs to support survivors of violence against women; yet little is known regarding the prevalence of such programs. In this study, we used data from three waves of the National Congregation Study (N = 3334) to examine change across time in the presence of a congregational program to support survivors of sexual assault or domestic violence. We also explored results among different Christian religious traditions across time. Given the gendered nature of this violence, we also tested whether the (a) gender of the head clergy (i.e., religious leader), and (b) ability of women to serve in congregational leadership roles predicted the presence of programs. As points of comparison, we also examined the total number of congregational social service programs and food programs in particular. Overall, we found different patterns of change across religious traditions for the different programs. Moreover, clergy gender and the ability of women to serve in leadership roles predicted the presence of different types of programs. Limitations, implications, and directions for future research also are discussed.
