The sound of spiritual care: music interventions in a palliative care setting

The article describes how music has been integrated into spiritual and supportive care for palliative care patients at Brantford General Hospital (Ontario). Numerous case examples illustrate how a song or piece of music can play a vital role in the spiritual dimension of end of life care. The article expands the concept of the "living human document" by positing that a life story has an accompanying soundtrack: a musical memory and sensorial attunement that can be energized when music is offered at the bedside. The writers suggest that music provides an alternate spiritual language for patients whether or not they have a religious affiliation.     

Continuous perception and graded categorization: electrophysiological evidence for a linear relationship between the acoustic signal and perceptual encoding of speech

Speech sounds are highly variable, yet listeners readily extract information from them and transform continuous acoustic signals into meaningful categories during language comprehension. A central question is whether perceptual encoding captures acoustic detail in a one-to-one fashion or whether it is affected by phonological categories. We addressed this question in an event-related potential (ERP) experiment in which listeners categorized spoken words that varied along a continuous acoustic dimension (voice-onset time, or VOT) in an auditory oddball task. We found that VOT effects were present through a late stage of perceptual processing (N1 component, ~100 ms poststimulus) and were independent of categorization. In addition, effects of within-category differences in VOT were present at a postperceptual categorization stage (P3 component, ~450 ms poststimulus). Thus, at perceptual levels, acoustic information is encoded continuously, independently of phonological information. Further, at phonological levels, fine-grained acoustic differences are preserved along with category information.     

Ceiling effects make Hughes and Nicholson’s data analyses and conclusions inconclusive

Hughes and Nicholson (2010) suggest that recognizing oneself is easier from face vs. voice stimuli, that a combined presentation of face and voice actually inhibits self-recognition relative to presentation of face or voice alone, that the left hemisphere is superior in self-recognition to the right hemisphere, and that recognizing self requires more effort than recognizing others. A re-examination of their method, data, and analyses unfortunately shows important ceiling effects that cast doubts on these conclusions.     

The Influence of a Manager's Own Performance Appraisal on the Evaluation of Others

This study examined the possibility that the performance appraisal process is affected by a pervasive and inherent effect that has heretofore been unidentified. This effect derives from the results of the performance appraisal most recently performed on the manager who subsequently conducts appraisals of others. The nature of this effect was examined in four studies. In a case study, the ratings received by two area coordinators in a university academic department affected their subsequent ratings of faculty. In a simulation, 30 managers received hypothetical feedback regarding their own job performance. The managers subsequently evaluated an employee on videotape. Managers who received positive feedback about their performance subsequently rated the employee significantly higher than managers who received negative feedback regarding their own performance. This occurred despite the fact that the managers knew the evaluation of them was bogus. The results of two follow‐up field studies involving 74 manager–employee dyads in a manufacturing company in Canada and 39 manager–subordinate dyads in a retail organization in Turkey are consistent with the view that one's own performance appraisal is related to the subsequent appraisal of one's subordinates. Both anchoring with insufficient adjustment and a mood induction may explain this effect, but the results are more consistent with the former explanation than the latter.     

Pain, dissociation and subliminal self-representations

According to recent evidence, neurophysiological processes coupled to pain are closely related to the mechanisms of consciousness. This evidence is in accordance with findings that changes in states of consciousness during hypnosis or traumatic dissociation strongly affect conscious perception and experience of pain, and markedly influence brain functions. Past research indicates that painful experience may induce dissociated state and information about the experience may be stored or processed unconsciously. Reported findings suggest common neurophysiological mechanisms of pain and dissociation and point to a hypothesis of dissociation as a defense mechanism against psychological and physical pain that substantially influences functions of consciousness. The hypothesis is also supported by findings that information can be represented in the mind/brain without the subject's awareness. The findings of unconsciously present information suggest possible binding between conscious contents and self-functions that constitute self-representational dimensions of consciousness. The self-representation means that certain inner states of own body are interpreted as mental and somatic identity, while other bodily signals, currently not accessible to the dominant interpreter's access are dissociated and may be defined as subliminal self-representations. In conclusion, the neurophysiological aspects of consciousness and its integrative role in the therapy of painful traumatic memories are discussed.     

Information selectivity in decision making by younger and older adults

Past research has demonstrated that older adults are more likely than younger adults to exhibit information selectivity in decision making. Two alternative explanations have been proposed to account for this age difference. One explanation attributes the increase in information selectivity to older adults' reliance on prior knowledge, whereas the other explanation suggests that it reflects reduced information processing capacity. The aim of this research was to explore the latter explanation by controlling for experiential factors and varying the cognitive demands involved in decision making. Specifically, participants were faced with unfamiliar decision problems, and had to base their decisions on the available information in order to reach a desired goal. In Experiment 1 younger and older participants were required to play a game involving chance. The outcome payoff was varied between three conditions (approach, avoidance, and control). The results indicated that both the younger and the older participants based their decisions on payoff, though the older participants did so to a lesser extent. In Experiment 2 younger and older participants performed a similar decision task but with higher cognitive demands. Specifically, the decision‐making task included two dimensions of information, outcome probability and outcome payoff. The results showed that the younger participants based their decisions on probability and payoff whereas the older participants based their decisions on probability alone. In Experiment 3 younger and older participants made decisions in a sale context and received instructional cue to incorporate payoff information in their decisions. As before, the younger participants utilized probability and payoff, whereas the older participants based their decisions only on probability information. The findings are discussed in terms of age differences in information‐processing capacity, metacognition, motivation, and goal‐setting.     

An assessment of response, direction and place learning by rats in a water T-maze

Behavioral data suggest that distinguishable orientations may be necessary for place learning even when distal cues define different start points in the room and a unique goal location. We examined whether changes in orientation are also important in place learning and navigation in a water T-maze. In Experiment 1, rats were trained to locate a hidden platform and given a no-platform probe trial after 16 and 64 trials with the maze moved to a new position. Direction and response strategies were more prevalent than a place strategy. In Experiment 2, acquisition of place, response and direction strategies was assessed in a water T-maze that was moved between two locations during training. Rats were impaired on the place task when the maze was translated (moved to the L or R) but were successful when the maze was rotated across trials. These data are consistent with findings from appetitive tasks.     

The psycho‐physical laws of intentionality

Intentional mental states have causes and effects. Davidson has shown that this fact alone does not entail the existence of psycho‐physical laws, but his anomalism makes the connection between the content and causation of intentional states utterly mysterious. By defining intentional states in terms of their causes and effects, functionalism promises to explain this connection. If intentional states have their causes and effects in virtue of their contents, then there must be intrinsic states (of the people who have them) which are ‘local causal surrogates’ for the propositions believed, desired, or whatever. We can define these intrinsic states in terms of the laws that govern them, but these laws alone are not sufficient to account for intentional content. To do that we need to invoke laws which link these intrinsic states with their contents. Such a ‘wide’ functional account is sketched; it combines a suggestion of Ramsey's about truth conditions with a ‘feedback’ account of the content of desires.
