Nocturne

A king must be willing to first lower himself and live the life of a common man, before rising once more to his full stature. Boromir fails this test (he who should have realized that he was a steward, not a king), but finally redeems himself in death. Strider/Aragorn fully passes his test and, unlike Boromir, does not die but instead triumphs over death, actually raising the Army of the Dead to help him in a great battle. After the Quest is completed—the ring is destroyed—Strider fully becomes Aragorn, reunites Gondor and Arnor, and is crowned king. His is the classic path of the hero, one that can teach all of us many lessons about our own individuation.     

An effect of mood on the perception of geographical slant

Previous research has shown that hills appear steeper to those who are fatigued, encumbered, of low physical fitness, elderly, or in declining health (Bhalla & Proffitt, 1999; Proffitt, Bhalla, Gossweiler, & Midgett, 1995). The prevailing interpretation of this research is that observers’ perceptions of the environment are influenced by their capacity to navigate that environment. The current studies extend this programme by investigating more subtle embodied effects on perception of slant; namely those of mood. In two studies, with two different mood manipulations, and two estimates of slant in each, observers in a sad mood reported hills to be steeper. These results support the role of mood and motivational factors in influencing spatial perception, adding to the previous work showing that energetic potential can influence perception.     

Increasing pretend toy play of toddlers with disabilities in an inclusive setting

We evaluated a program for increasing pretend toy play of 2-year-old children with disabilities in an inclusive classroom. Classroom personnel implemented the program, which involved choices of classroom centers containing toys that tend to occasion pretend play in toddlers without disabilities, along with prompting and praise. Increases occurred in independent pretend-play rates among all 5 participating toddlers. Results are discussed regarding the importance of promoting toy play of very young children with disabilities that is similar to the type of play of their nondisabled peers, and the need to identify critical program components that are applicable in inclusive settings.

Correlations among within-channel and between-channel auditory gap-detection thresholds in normal listeners

We obtained data on within-channel and between-channel auditory temporal gap-detection acuity in the normal population. Ninety-five normal listeners were tested for gap-detection thresholds, for conditions in which the gap was bounded by spectrally identical, and by spectrally different, acoustic markers. Separate thresholds were obtained with the use of an adaptive tracking method, for gaps delimited by narrowband noise bursts centred on 1.0 kHz, noise bursts centred on 4.0 kHz, and for gaps bounded by a leading marker of 4.0 kHz noise and a trailing marker of 1.0 kHz noise. Gap thresholds were lowest for silent periods bounded by identical markers--'within-channel' stimuli. Gap thresholds were significantly longer for the between-channel stimulus--silent periods bounded by unidentical markers (p < 0.0001). Thresholds for the two within-channel tasks were highly correlated (R = 0.76). Thresholds for the between-channel stimulus were weakly correlated with thresholds for the within-channel stimuli (1.0 kHz, R = 0.39; and 4.0 kHz, R = 0.46). The relatively poor predictability of between-channel thresholds from the within-channel thresholds is new evidence on the separability of the mechanisms that mediate performance of the two tasks. The data confirm that the acuity difference for the tasks, which has previously been demonstrated in only small numbers of highly trained listeners, extends to a population of untrained listeners. The acuity of the between-channel mechanism may be relevant to the formation of voice-onset time-category boundaries in speech perception.     

Phonological and conceptual activation in speech comprehension

We propose that speech comprehension involves the activation of token representations of the phonological forms of current lexical hypotheses, separately from the ongoing construction of a conceptual interpretation of the current utterance. In a series of cross-modal priming experiments, facilitation of lexical decision responses to visual target words (e.g., time) was found for targets that were semantic associates of auditory prime words (e.g., date) when the primes were isolated words, but not when the same primes appeared in sentence contexts. Identity priming (e.g., faster lexical decisions to visual date after spoken date than after an unrelated prime) appeared, however, both with isolated primes and with primes in prosodically neutral sentences. Associative priming in sentence contexts only emerged when sentence prosody involved contrastive accents, or when sentences were terminated immediately after the prime. Associative priming is therefore not an automatic consequence of speech processing. In no experiment was there associative priming from embedded words (e.g., sedate-time), but there was inhibitory identity priming (e.g., sedate-date) from embedded primes in sentence contexts. Speech comprehension therefore appears to involve separate distinct activation both of token phonological word representations and of conceptual word representations. Furthermore, both of these types of representation are distinct from the long-term memory representations of word form and meaning.     

Multiple-family group treatment of outpatients with schizophrenia: impact on service utilization

The impact of multiple-family group treatment (MFGT) on outpatient and inpatient mental health service utilization of 97 persons with schizophrenia was investigated. Participants were randomly assigned to standard care (n = 44) or standard care plus MFGT (n = 53). Service use for a year prior to randomization, the 2-year study period, and a 1-year follow-up were examined. Relative to standard care participants, the MFGT group had reduced community hospitalization during year 1 of the intervention and reduced state hospitalization at follow-up. During the intervention period, MFGT participants demonstrated a significant increase in outpatient utilization as a direct consequence of the intervention. However, when service use was summed across 3 years post-randomization, no group differences were observed. Results suggest that implementation of MFGT in a community mental health setting reduces inpatient service at specific time periods, without significantly increasing outpatient service utilization. These findings add to other outcomes from this study that demonstrate decreased psychiatric symptoms and caregiver distress.     

The Bayesian reader: explaining word recognition as an optimal Bayesian decision process

This article presents a theory of visual word recognition that assumes that, in the tasks of word identification, lexical decision, and semantic categorization, human readers behave as optimal Bayesian decision makers. This leads to the development of a computational model of word recognition, the Bayesian reader. The Bayesian reader successfully simulates some of the most significant data on human reading. The model accounts for the nature of the function relating word frequency to reaction time and identification threshold, the effects of neighborhood density and its interaction with frequency, and the variation in the pattern of neighborhood density effects seen in different experimental tasks. Both the general behavior of the model and the way the model predicts different patterns of results in different tasks follow entirely from the assumption that human readers approximate optimal Bayesian decision makers.     

New Factor Structure of the Interpretation of Intrusions Inventory with University Students

The Obsessive Compulsive Cognitions Working Group (OCCWG) created the Interpretation of Intrusions Inventory (III) to measure appraisals (interpretations) of mental intrusions. Validation attempts by the OCCWG suggest that the three appraisal mechanisms hypothesized to comprise the III are better described as a single construct. The underlying factor structure of the III was investigated with university students (n = 307). Confirmatory factor analyses were conducted on the theoretically-derived three-factor model and on the empirically-derived one-factor model of the III. Both models failed to adequately fit the data. Thus, an exploratory factor analysis was conducted, which produced a two-factor model consisting of appraisals of Responsibility and Importance/Control of Thoughts. The new factors exhibited good predictive validity, as they predicted the severity of obsessive-compulsive symptoms and subtypes of obsessive-compulsive disorder (OCD).

Bias effects in facilitatory phonological priming

In four experiments, we examined the facilitation that occurs when spoken-word targets rhyme with preceding spoken primes. In Experiment 1, listeners' lexical decisions were faster to words following rhyming words (e.g., ramp-LAMP) than to words following unrelated primes (e.g., pink-LAMP). No facilitation was observed for nonword targets. Targets that almost rhymed with their primes (foils; e.g., bulk-SULSH) were included in Experiment 2; facilitation for rhyming targets was severely attenuated. Experiments 3 and 4 were single-word shadowing variants of the earlier experiments. There was facilitation for both rhyming words and nonwords; the presence of foils had no significant influence on the priming effect. A major component of the facilitation in lexical decision appears to be strategic: listeners are biased to say "yes" to targets that rhyme with their primes, unless foils discourage this strategy. The nonstrategic component of phonological facilitation may reflect speech perception processes that operate prior to lexical access.
