Sentence representations and anaphor processing

This paper describes the use of anaphora to explore the nature of the representation constructed during the on-line processing of sentences. The central concern of the study was to discover whether this representation is componential or holistic. It was found that subjects took longer to resolve references to objects rather than events and, more interesting, that the componential complexity of the target representation affected the speed of anaphor resolution. The results suggest that events are represented differently from objects, and that the representation of events is componential.     

Occupational level and mental health: A note

Investigation of mental health and job satisfaction by means of Kornhauser's (1965) questionnaire appears to demonstrate the existence of at least six factors concerned with personal life adjustment. There was a failure to find any substantial relationship between mental health and job satisfaction over a fairly wide occupational distribution which confirms a finding by the previously cited Survey Research Center study 1970. It is hypothesized that the mental health-job satisfaction relationship exists only on the lower skill, routine work level. It is further suggested that these research results offer certain directions that might be pursued in the further understanding of the exact bases for both job and general life adjustment.     

Lexical and semantic fluency discrepancy scores in aMCI and early Alzheimer's disease

Episodic memory is compromised in amnestic mild cognitive impairment (aMCI), but lesser deficits in other cognitive domains are also commonly observed and may be helpful in identifying this group. The relative difference in performance on lexical and semantic fluency tasks may be a sensitive and specific measure in aMCI and early Alzheimer's disease (AD). We compared four groups of participants, 35 early AD, 47 aMCI, 24 healthy controls, and 18 depressive out‐patient controls, on semantic and lexical fluency as well as other neuropsychological tests. Early AD and aMCI patients showed a distinct pattern of semantic impairment in the two fluency measures compared with the healthy and depressive controls. The findings implicate early failure of the semantic memory system in aMCI and AD and suggest that consideration of the discrepancy in performance on semantic and lexical fluency measures may help in the early identification of AD.     

Words in the brain's language: an experimental investigation

According to Pulvermüller (1999), words are represented in the brain by cell assemblies (Hebb, 1949) distributed over different areas, depending on semantic properties of the word. For example, a word with strong visual associations will be represented by a cell assembly involving neurons in the visual cortex, while a word suggesting action will selectively activate neurons in the motor areas. The present work aims to test the latter hypothesis by means of behavioural measures. Specifically it tests the prediction that there should be a selective influence (in terms either of interference or priming) of performed/observed movements on the performance (reaction times and accuracy) of lexical decision involving words with a strong action association. Similarly, a selective influence of visual images on lexical decision involving words with strong visual associations should be observed. Two experiments were carried out. Results provided partial support for the hypothesis.     

A system for tracking braille readers using a Wii Remote and a refreshable braille display

This article describes a cheap and easy-to-use finger-tracking system for studying braille reading. It provides improved spatial and temporal resolution over the current available solutions and can be used with either a refreshable braille display or braille-embossed paper. In conjunction with a refreshable braille display, the tracking system has the unique capacity to implement display-change paradigms derived from sighted reading research. This will allow researchers to probe skilled braille reading in significantly more depth than has heretofore been possible.     

Living liver donation: Attitudes of the general public and general practitioners in Scotland

In April 2006, the Scottish Liver Transplant Unit in Edinburgh became the first NHS transplant unit in the UK to offer adult-to-adult living donor liver transplantation (LDLT). This procedure allows a healthy individual to donate part of their liver to someone with end-stage liver disease. With donations from the deceased in short supply, this procedure has the capacity to save lives. The aim of this study was to explore the attitudes of the general public and general practitioners (GPs) towards LDLT, before its implementation. A total of 1041 members of the Scottish general public and 155 GPs working in Scotland completed a short questionnaire devised for this study. The majority of participants supported the option of LDLT, but frequency counts showed that only 34% of the general public wish to donate their organs following death compared to 85% of GPs. With regards to an acceptable risk of death before volunteering to donate, 25% of GPs would accept a 1 in 20 risk of death, whereas 50% of the general public either could not make a decision or selected ‘No risk’. The question of how well people understand the concept of risk was again highlighted in this study.     

Difficulties adjusting to post-discharge life following a spinal cord injury: an interpretative phenomenological analysis

Individual semi-structured interviews were conducted with 17 individuals who had experienced a traumatic spinal cord injury (SCI), focusing on the participants' lived experience of SCI. The interviews were transcribed verbatim and were analysed for recurrent themes using interpretative phenomenological analysis (IPA). Here, we present three inter-related recurrent themes all concerning difficulties in adjusting to home life following hospital discharge: "loss of camaraderie", "lack of post-discharge care" and "other people's reactions to spinal cord injury". Participants reported that the camaraderie they formed with fellow patients during their rehabilitative stay in hospital generated feelings of security and community. This was discussed in stark contrast to the isolation and loneliness that they subsequently experienced post-hospital discharge. A perceived lack of physical, practical and psychological support coupled with negative and stigmatising reactions of the wider community served to make adjustment to home life post-SCI particularly difficult for the participants. The findings are discussed in relation to extant SCI literature, and recommendations for future health care of individuals with SCI are made.     

Memory bias for emotional facial expressions in major depression

Sixteen clinically depressed patients and sixteen healthy controls were presented with a set of emotional facial expressions and were asked to identify the emotion portrayed by each face. They, were subsequently given a recognition memory test for these faces. There was no difference between the groups in terms of their ability to identify emotion between from faces. All participants identified emotional expressions more accurately than neutral expressions, with happy expressions being identified most accurately. During the recognition memory phase the depressed patients demonstrated superior memory for sad expressions, and inferior memory for happy expressions, relative to neutral expressions. Conversely, the controls demonstrated superior memory for happy expressions, and inferior memory for sad expressions, relative to neutral expressions. These results are discussed in terms of the cognitive model of depression proposed by Williams, Watts, MacLeod, and Mathews (1997).
