The use of virtual reality (VR) to create immersive experiences through the principles taught in art and design curricula has been studied over the past two decades while, at the same time, demonstrating positive correlations between learning outcomes and the technology. Not surprisingly, the creation of 3D models within a virtual environment leads to a better understanding of 3D workflow. Yet, despite these developments, few studies have been conducted specifically on the application within a studio context for art and design disciplines and how VR might benefit artists and designers. This study confirms that the use of VR in art and design courses is perceived to promote a better understanding of three-dimensional spaces, design and to improve student-centred activities and student–student interactions. At the same time, integrating VR into curriculum should be strategic and aligned with learning outcomes for impactful learning experiences. [ABSTRACT FROM AUTHOR]

Objective: The study evaluated the use and effectiveness of a progress monitoring system routinely operational in a private mental health care setting. Method: In a nonrandomized trial in which 778 consecutively admitted patients underwent a 2-week cognitive behavioral therapy intervention, the effectiveness of therapists choosing to use progress monitoring feedback to frame therapist–patient discussions about individuals' progress was evaluated. Results: Patients engaged in discussions involving progress monitoring feedback during the intervention achieved a more consistent recovery rate. Furthermore, individuals that were not-on-track to achieve a positive outcome experienced a boost to recovery immediately after receiving feedback. However, evidence suggested that therapists were not using progress monitoring to primarily focus additional resources on not-on-track patients. Conclusion: Progress monitoring feedback benefited patient recovery. However, guidelines could improve the system by directing therapists to use feedback primarily with patients not on course for a positive therapeutic outcome. [ABSTRACT FROM AUTHOR]

The hypothesis that known words can serve as anchors for discovering new words in connected speech has computational and empirical support. However, evidence for how the bootstrapping effect of known words interacts with other mechanisms of lexical acquisition, such as statistical learning, is incomplete. In 3 experiments, we investigated the consequences of introducing a known word in an artificial language with no segmentation cues other than cross-syllable transitional probabilities. We started with an artificial language containing 4 trisyllabic novel words and observed standard above-chance performance in a subsequent recognition memory task. We then replaced 1 of the 4 novel words with a real word (tomorrow) and noted improved segmentation of the other 3 novel words. This improvement was maintained when the real word was a different length to the novel words (philosophy), ruling out an explanation based on metrical expectation. The improvement was also maintained when the word was added to the 4 original novel words rather than replacing 1 of them. Together, these results show that known words in an otherwise meaningless stream serve as anchors for discovering new words. In interpreting the results, we contrast a mechanism where the lexical boost is merely the consequence of attending to the edges of known words, with a mechanism where known words enhance sensitivity to transitional probabilities more generally.

Statistical learning (SL) is a powerful learning mechanism that supports word segmentation and language acquisition in infants and young adults. However, little is known about how this ability changes over the life span and interacts with age-related cognitive decline. The aims of this study were to: (a) examine the effect of aging on speech segmentation by SL, and (b) explore core mechanisms underlying SL. Across four testing sessions, young, middle-aged, and older adults were exposed to continuous speech streams at two different speech rates, both with and without cognitive load. Learning was assessed using a two-alterative forced-choice task in which words from the stream were pitted against either part-words, which occurred across word boundaries in the stream, or nonwords, which never appeared in the stream. Participants also completed a battery of cognitive tests assessing working memory and executive functions. The results showed that speech segmentation by SL was remarkably resilient to aging, although age effects were visible in the more challenging conditions, namely, when words had to be discriminated from part-words, which required the formation of detailed phonological representations, and when SL was performed under cognitive load. Moreover, an analysis of the cognitive test data indicated that performance against part-words was predicted mostly by memory updating, whereas performance against nonwords was predicted mostly by working memory storage capacity. Taken together, the data show that SL relies on a combination of implicit and explicit skills, and that age effects on SL are likely to be linked to an age-related selective decline in memory updating.

A number of studies have recently reported that in picture–word interference (PWI) tasks, distractors with a low frequency of occurrence interfere more with picture naming than distractors with high-frequency. This finding is not straightforward to accommodate within traditional accounts of word production in which lexical access is typically conceptualised as competitive. Instead, the distractor frequency effect has been taken to support a view according to which lexical access is not competitive, and PWI effects arise at a postlexical preparation stage. Two experiments are reported which contrasted picture naming with a manual task performed on the picture name (Experiment 1: syllable judgment; Experiment 2: phoneme monitoring). In both studies, an equivalent effect of distractor frequency was observed for vocal and manual tasks, suggesting that the effect arises at a shared, abstract processing level. Consequently, the distractor frequency effect should not be interpreted as evidence for the claim that distractors have to be excluded from an articulatory response buffer before target naming can proceed.

OBJECTIVES Although the adipocyte protein leptin has been implicated in the control of reproductive function in rodents, its role in primate reproductive physiology is poorly understood. Because primates in puberty show nighttime LH secretion and there is considerable evidence that the fertile state requires adequate nutrition, we reasoned that animals on the verge of reproductive competence would respond to leptin infusions by secreting LH. Food restriction reduces circulating leptin levels and slows or stops the GnRH pulse generator. Therefore, we examined the endocrine effects of leptin infusions in food-restricted male pubertal primates during the night when they normally secrete LH. In addition, we investigated the effect of leptin on in vitro testosterone production by Leydig cells. SUBJECTS Four pubertal male rhesus macaques (Macaca mulatta), 4–5.5 kg in weight (2.5–4-year-old) were examined in this study. Leydig cells from adult male rats were to investigate in vitro effects of leptin. DESIGN To document that animals had entered puberty, blood samples were collected from each of the four animals at 15-minute intervals for 15 h both during the day and at night. Since at this age animals secrete LH mainly at night, blood samples were collected at 15-minute intervals from each of the four animals on two separate occasions for 15 h between 1500 and 0600h. During the experiment, animals were feeding from 0800 to 0830h, cages were completely cleaned of food at 0900h and the afternoon meal was not given to individual animals on the day they were studied. One of the studies served as the control (food restricted group) and during the other, 2 mg (n = 4) or 0.3 mg (n = 3) of recombinant human leptin was administered intravenously during 2000–0100h (food restricted plus leptin group). Blood samples (1 ml) were collected through the indwelling catheter and immediately transferred from the plastic syringe into chilled glass tubes containing 10... [ABSTRACT FROM AUTHOR]
