Studies on preference assessments have shown that when both edible and leisure items are compared, edible items tend to displace leisure items in preference hierarchies. However, the mechanisms behind this process are currently unclear. One possibility is that displacement may be a product of the relatively brief periods of access to leisure items typically used in preference assessments. The purpose of the current investigation was to examine whether the duration of access to leisure items affects displacement. In this study, participants chose between preferred leisure items and the edible items that had previously been shown to displace those leisure items in a preference hierarchy. Duration of access to the leisure item was systematically increased across series to identify the magnitude at which leisure items became more preferred than edible items. Results indicate that as the duration of access to leisure items increases, displacement decreases.

Background: Science of anaesthesia has revolutionized from traditional only application of relieving patient from pain induced during surgery to wide spectrum approaches like palliative care, critical care, perioperative care along with pain management. Despite of such critical roles in health care sector there is still a lack of awareness about anaesthesiology and anaesthesiologists. Current investigation was aimed towards assessing the awareness of paramedical staff regarding the role of anesthesiology.Methods: Current investigation was a prospective cross-sectional questionnaire-based study conducted on 100 paramedical staff posted in different departments of military hospital Jaipur.  All the study participants were interviewed face to face orally by an investigator using the set of questions listed in the questionnaire. Participants responses were documented and statistically represented as percentage.Results: Current study findings reveal that even though majority of the study participants (91) had experience more than 5 years in the hospital and most of them (˃90%) of participants were having educational level of higher secondary or graduation still the role of anaesthesiologist outside operation theatre was poorly known to paramedical staff. It was also observed in current investigation that role of anesthetist in pain clinic was poorly known to most of the participating paramedical staff.Conclusions: Providing knowledge about expertise of anesthesiologist among paramedical staffs by incorporating anaesthesia in the curriculum, in house training programs, use of pamphlets, internet and other easily assessable techniques is highly desirable for spreading awareness of anaesthesia and anesthetist among paramedical staff, so that patient can avail anaesthesia related services effectively.

The effect of shock loading on a variety of steels has been reviewed recently by Leslie. It is generally observed that significant changes in microstructure and microhardness are produced by explosive shock deformation. While the effect of shock loading on austenitic, ferritic, martensitic, and pearlitic structures has been investigated, there have been no systematic studies of the shock-loading of microduplex structures.In the current investigation, the shock-loading response of millrolled and heat-treated Uniloy 326 (thickness 60 mil) having a residual grain size of 1 to 2μ before shock loading was studied. Uniloy 326 is a two phase (microduplex) alloy consisting of 30% austenite (γ) in a ferrite (α) matrix; with the composition.3% Ti, 1% Mn, .6% Si,.05% C, 6% Ni, 26% Cr, balance Fe.

Purpose Previous research with children with and without disabilities has demonstrated that visual–perceptual factors can influence the speech of locating a target on an array. Adults without disabilities often facilitate the learning and use of a child's augmentative and alternative communication system. The current research examined how the presence of symbol background color influenced the speed with which adults without disabilities located target line drawings in 2 studies. Method Both studies used a between-subjects design. In the 1st study, 30 adults (ages 18–29 years) located targets in a 16-symbol array. In the 2nd study, 30 adults (ages 18–34 years) located targets in a 60-symbol array. There were 3 conditions in each study: symbol background color, symbol background white with a black border, and symbol background white with a color border. Results In the 1st study, reaction times across groups were not significantly different. In the 2nd study, participants in the symbol background color condition were significantly faster than participants in the other conditions, and participants in the symbol background white with black border were significantly slower than participants in the other conditions. Conclusion Communication partners may benefit from the presence of background color, especially when supporting children using displays with many symbols.

Purpose The current study aimed to identify factors that distinguish between older (50+ years) hearing aid (HA) candidates who do and do not purchase HAs after having gone through an HA evaluation period (HAEP). Method Secondary data analysis of the SUpport PRogram trial was performed ( n = 267 older, 1st-time HA candidates). All SUpport PRogram participants started an HAEP shortly after study enrollment. Decision to purchase an HA by the end of the HAEP was the outcome of interest of the current study. Participants' baseline covariates (22 in total) were included as candidate predictors. Multivariable logistic regression modeling (backward selection and reclassification tables) was used. Results Of all candidate predictors, only pure-tone average (average of 1, 2, and 4 kHz) hearing loss emerged as a significant predictor (odds ratio = 1.03, 95% confidence interval [1.03, 1.17]). Model performance was weak (Nagelkerke R 2 = .04, area under the curve = 0.61). Conclusions These data suggest that, once HA candidates have decided to enter an HAEP, factors measured early in the help-seeking journey do not predict well who will and will not purchase an HA. Instead, factors that act during the HAEP may hold this predictive value. This should be examined.

Purpose This study investigated the nature of the association of lexical–grammatical abilities within and across languages in Latino dual language learners (DLLs) with specific language impairment (SLI) using language-specific and bilingual measures. Method Seventy-four Spanish/English–speaking preschoolers with SLI from preschools serving low-income households participated in the study. Participants had stronger skills in Spanish (first language [L1]) and were in the initial stages of learning English (second language [L2]). The children's lexical, semantic, and grammar abilities were assessed using normative and researcher-developed tools in English and Spanish. Hierarchical linear regressions of cross-sectional data were conducted using measures of sentence repetition tasks, language-specific vocabulary, and conceptual bilingual lexical and semantic abilities in Spanish and English. Results Results indicate that language-specific vocabulary abilities support the development of grammar in L1 and L2 in this population. L1 vocabulary also contributes to L2 grammar above and beyond the contribution of L2 vocabulary skills. However, the cross-linguistic association between vocabulary in L2 and grammar skills in the stronger or more proficient language (L1) is not observed. In addition, conceptual vocabulary significantly supported grammar in L2, whereas bilingual semantic skills supported L1 grammar. Conclusions Our findings reveal that the same language-specific vocabulary abilities drive grammar development in L1 and L2 in DLLs with SLI. In the early stages of L2 acquisition, vocabulary skills in L1 also seem to contribute to grammar skills in L2 in this population. Thus, it is critical to support vocabulary development in both L1 and L2 in DLLs with SLI, particularly in the beginning stages of L2 acquisition. Clinical and educational implications are discussed.

Purpose Speech-language pathologists (SLPs) anecdotally report concern that their interactions with a child who stutters, including even the use of the term “stuttering,” might contribute to negative affective, behavioral, and cognitive consequences. This study investigated SLPs' comfort in providing a diagnosis of “stuttering” to children's parents/caregivers, as compared to other commonly diagnosed developmental communication disorders. Method One hundred forty-one school-based SLPs participated in this study. Participants were randomly assigned to one of two vignettes detailing an evaluation feedback session. Then, participants rated their level of comfort disclosing diagnostic terms to parents/caregivers. Participants provided rationale for their ratings and answered various questions regarding academic and clinical experiences to identify factors that may have influenced ratings. Results SLPs were significantly less likely to feel comfortable using the term “stuttering” compared to other communication disorders. Thematic responses revealed increased experience with a specific speech-language population was related to higher comfort levels with using its diagnostic term. Additionally, knowing a person who stutters predicted greater comfort levels as compared to other clinical and academic experiences. Conclusions SLPs were significantly less comfortable relaying the diagnosis “stuttering” to families compared to other speech-language diagnoses. Given the potential deleterious effects of avoidance of this term for both parents and children who stutter, future research should explore whether increased exposure to persons who stutter of all ages systematically improves comfort level with the use of this term.

Abstract. Neurocognitive deficits in patients with mental disorders are partially due to secondary influences. “Stereotype threat” denotes the phenomenon that performance is compromised when a participant is confronted with a devaluing stereotype. The present study examined the impact of stereotype threat on neuropsychological performance in schizophrenia. Seventy-seven participants with a self-reported diagnosis of schizophrenia were randomly assigned to either an experimental condition involving stereotype threat activation or a control condition in an online study. Participants completed memory and attention tests as well as questionnaires on motivation, self-efficacy expectations, cognitive complaints, and self-stigmatization. Contrary to our prediction, the two groups showed no significant differences regarding neuropsychological performance and self-report measures. Limitations, such as a possibly too weak threat cue, are discussed and recommendations for future studies are outlined.

Two experiments investigate effects related to food intake in humans. In Experiment 1, we measured startle response modulation while study participants ate ice cream, yoghurt, and chocolate. Statistical analysis revealed that ice cream intake resulted in the most robust startle inhibition compared to no food. Contrasting females and males, we found significant differences related to the conditions yoghurt and chocolate. In females, chocolate elicited the lowest response amplitude followed by yoghurt and ice cream. In males, chocolate produced the highest startle response amplitude even higher than eating nothing, whereas ice cream produced the lowest. Assuming that high response amplitudes reflect aversive motivation while low response amplitudes reflect appetitive motivational states, it is interpreted that eating ice cream is associated with the most appetitive state given the alternatives of chocolate and yoghurt across gender. However, in females alone eating chocolate, and in males alone eating ice cream, led to the most appetitive state. Experiment 2 was conducted to describe food intake-related brain activity by means of source localization analysis applied to electroencephalography data (EEG). Ice cream, yoghurt, a soft drink, and water were compared. Brain activity in rostral portions of the superior frontal gyrus was found in all conditions. No localization differences between conditions occurred. While EEG was found to be insensitive, startle response modulation seems to be a reliable method to objectively quantify motivational states related to the intake of different foods.

Abstract. Folk wisdom tells us that additional time to make a decision helps us to refrain from the first impulse to take the bird in the hand. However, the question why the time to decide plays an important role is still unanswered. Here we distinguish two explanations, one based on a bias in value accumulation that has to be overcome with time, the other based on cognitive control processes that need time to set in. In an intertemporal decision task, we use mouse tracking to study participants’ responses to options’ values and delays which were presented sequentially. We find that the information about options’ delays does indeed lead to an immediate bias that is controlled afterwards, matching the prediction of control processes needed to counter initial impulses. Hence, by using a dynamic measure, we provide insight into the processes underlying short-term oriented choices in intertemporal decision making.

Two distinct spatial metaphors for the passage of time can produce disparate judgments about grieving. Under the object-moving metaphor, time seems to move past stationary people, like objects floating past people along a riverbank. Under the people-moving metaphor, time is stationary; people move through time as though they journey on a one-way street, past stationary objects. The people-moving metaphor should encourage the forecast of shorter grieving periods relative to the object-moving metaphor. In the present study, participants either received an object-moving or people-moving prime, then read a brief vignette about a mother whose young son died. Participants made affective forecasts about the mother’s grief intensity and duration, and provided open-ended inferences regarding a return to relative normalcy. Findings support predictions, and are discussed with respect to interpersonal communication and everyday life.
