The effect of Alzheimer's disease and aging on conceptual combination

Alzheimer's disease (AD) subjects, healthy elderly, and young adults interpreted a series of novel noun-noun expressions composed of familiar object words. Subjects interpreted each item by selecting one of three possible definitions: a definition in which the referents of each noun were associated together in a particular context (e.g., rabbit cat: a cat that is raised by rabbits); a definition based on integrating the semantic attributes from each noun into a single referent (e.g., rabbit cat: a cat that has long ears and hops); and a semantic foil. The results show that the AD subjects selected significantly fewer integrational definitions and significantly more foils than healthy elderly subjects. Healthy elderly participants were also found to select significantly more foil definitions than the young adult subjects. These findings suggest that AD individuals have difficulty in integrating semantic features when interpreting novel noun-noun expressions and that both AD and healthy elderly individuals have morphosyntactic impairments related to the identification of the modifying and head nouns of noun-noun expressions.     

Differential effects of manual assisted cognitive behavior therapy in the treatment of recurrent deliberate self-harm and personality disturbance: the POPMACT study

A total of 480 patients were treated in a large, multicenter randomized trial of a brief form of cognitive therapy, manual-assisted cognitive behavior therapy (MACT) versus treatment as usual (TAU) for recurrent deliberate self-harm. Each patient was randomized after a self-harm episode assessed at an accident and emergency center and followed up over 1 year. The main hypothesis tested was that those allocated to MACT would have a lower proportion of self-harm episodes in the succeeding year. A total of 60% of those allocated to MACT had face-to-face treatment and 430 (90%) of all patients had self-harm data recorded after 1 year. Although the results showed no significant difference between those repeating self-harm in the MACT group (39%) compared with the TAU group (46%) (P = 0.20), the treatment was cost effective (10% cheaper than TAU) and the frequency of self-harm episodes was fewer (50%) in the MACT group. A total of nine of 10 patients had some personality disturbance (42% of these with disorder), and for those where information on parasuicide events was collected, the proportion having a repeat episode ranged from 33% to 63% for different personality disorders. Those with BPD were most likely to repeat episodes quickly (mean 89 days for 25% to repeat) with dissocial personality disorder (equivalent mean 384 days) the slowest to repeat. Total costs were significantly greater in those with personality disorder and were reduced in those allocated to MACT; this saving was reversed in those with borderline disorder. On average, MACT appeared to increase the cost of those patients with BPD (BPD) and reduce the cost of those with other personality disorders. It is concluded that MACT has value in preventing self-harm cost effectively but this appears to be confined mainly to those who do not have BPD.     

Listening back in time: Does attention to memory facilitate word-in-noise identification?

The ephemeral nature of spoken words creates a challenge for oral communications where incoming speech sounds must be processed in relation to representations of just-perceived sounds stored in short-term memory. This can be particularly taxing in noisy environments where perception of speech is often impaired or initially incorrect. Usage of prior contextual information (e.g., a semantically related word) has been shown to improve speech in noise identification. In three experiments, we demonstrate a comparable effect of a semantically related cue word placed after an energetically masked target word in improving accuracy of target-word identification. This effect persisted irrespective of cue modality (visual or auditory cue word) and, in the case of cues after the target, lasted even when the cue word was presented up to 4 seconds after the target. The results are framed in the context of an attention to memory model that seeks to explain the cognitive and neural mechanisms behind processing of items in auditory memory.     

Lexical access in younger and older adults: the case of the mass/count distinction.

Although lexicosemantic deficits are not typically seen in older adults, some studies indicate that age-related changes in semantic processing may occur. We had groups of older and younger adults perform speeded lexical decision on mass (e.g., honey), count (e.g., car), and dual nouns, which may be either mass or count (e.g., lamb). Singular dual nouns engendered significantly faster response times in older adults than mass and count nouns, whereas younger adults manifested similar response times to count and dual nouns. These results point toward a three-way distinction in the lexicon between mass, count, and dual nouns. Older adults appear to treat a larger set of nouns as dual than do younger adults. This may be due to awareness of the mass/count ambiguity present in a greater number of lexical items, as a result of their greater linguistic experience. Alternatively, in order to conserve processing resources, older adults may not activate mass/count information when recognizing a dual noun unless a mass or count reading is forced by context.     

“Be Prepared if I Bring It Up:” Patients’ Perceptions of the Utility of Religious and Spiritual Discussion During Genetic Counseling

As debates continue about the relevance of religion to health care, research is needed to guide decisions about whether genetic counselors (GCs) should routinely address religious and/or spiritual (R/S) issues with their patients. We conducted an online survey to gauge patient perspectives on this issue. Among the 70 respondents, frequencies of closed-ended responses and thematic analyses of open-ended responses revealed multiple patient concerns related to R/S discussions with GCs. Although 60 respondents reported being R/S, only a small minority would want to discuss R/S issues if it meant less time discussing medical information. Most respondents also expressed opinions that: 1) genetic counseling should be about science; 2) GCs are not qualified to discuss R/S issues; 3) other outlets are available to meet the needs of patients who want R/S counseling; and/or 4) R/S discussions are more likely to be acceptable if patients broach the topic or in specific circumstances (e.g., when patients are facing end-of life issues). Overall, responses suggest routine or comprehensive R/S assessments or discussions are not necessary and that GCs would be best equipped to help all their patients if they were prepared to listen, be supportive, and make referrals when R/S issues arise in clinic.

A Cluster Analysis of Peer Support Training Needs for Foster Parents

Peer volunteers provide valuable support to foster parents. However, there has been limited research on what they consider to be valuable preparation for the role. In the present study, they were asked: “What is essential training for peer support volunteers to receive before starting?”. Fifteen participants grouped 41 different responses that were analyzed using multidimensional scaling and cluster analyses. The resulting concepts included: (a) self-care, (b) effective use of self, (c) policies and procedures, (d) finding information and (e) how to address common challenges.
