Profiles of Student Perceptions of School Climate: Relations with Risk Behaviors and Academic Outcomes

School climate has been linked to a variety of positive student outcomes, but there may be important within‐school differences among students in their experiences of school climate. This study examined within‐school heterogeneity among 47,631 high school student ratings of their school climate through multilevel latent class modeling. Student profiles across 323 schools were generated on the basis of multiple indicators of school climate: disciplinary structure, academic expectations, student willingness to seek help, respect for students, affective and cognitive engagement, prevalence of teasing and bullying, general victimization, bullying victimization, and bullying perpetration. Analyses identified four meaningfully different student profile types that were labeled positive climate, medium climate‐low bullying, medium climate‐high bullying, and negative climate. Contrasts among these profile types on external criteria revealed meaningful differences for race, grade‐level, parent education level, educational aspirations, and frequency of risk behaviors.     

The Role of Deviant Lifestyles on Violent Victimization in Multiple Contexts

Little research utilizing lifestyles theory (Hindelang, Gottfredson, and Garofalo 1978) has examined the role that deviant lifestyles have on the likelihood of witnessing violence among ethnic-minority youth across various contexts. Therefore, we examined the effects of indicators of a deviant lifestyle (delinquent behavior and deviant peers) on exposure to both direct and indirect forms of violence across three contexts (home, school, and community) among 233 11th graders. Findings indicated that the effects of deviant lifestyle indicators on violence vary by context. Results suggest that lifestyles theory may be applicable for predicting the likelihood of witnessing violence among minority youth across contexts.

Poor emotional responsiveness in clinical hypertension: Reduced accuracy in the labelling and matching of emotional faces amongst individuals with hypertension and prehypertension

Psychological factors are known to play an important part in the origin of many medical conditions including hypertension. Recent studies have reported elevated blood pressure (even in the normal range of variation) to be associated with a reduced responsiveness to emotions or ‘emotional dampening’. Our aim was to assess emotional dampening in individuals with more extreme blood pressure levels including prehypertensives (N = 58) and hypertensives (N = 60) by comparing their emotion recognition ability with normotensives (N = 57). Participants completed novel facial emotion matching and facial emotion labelling tasks following blood pressure measurement and their accuracy of emotion recognition and average response times were compared. The normotensives demonstrated a significantly higher accuracy of emotion recognition than the prehypertensives and the hypertensives in labelling of facial emotions. This difference generalised to the task where two facial halves (upper & lower) had to be matched on the basis of emotions. In neither the labelling nor matching emotion conditions did the groups differ in their speed of emotion processing. Findings of the present study extend reports of ‘emotional dampening’ to hypertensives as well as to those at-risk for developing hypertension (i.e. prehypertensives) and have important implications for understanding the psychological component of such medical conditions as hypertension.     

Evidence of rapid recovery from perceptual odor adaptation using a new stimulus paradigm

By attenuating neural and perceptual responses to sustained stimulation, adaptation enhances the detection of new, transient stimuli. Disadaptation serves a similarly important role as a temporal filter for chemoreceptor cells, producing rapid recovery of sensitivity upon termination of the adapting odorant. Previous research from our laboratory indicated that a rapid form of odor adaptation can be measured using a novel, simultaneous-odorant paradigm. In the present study, we extended the earlier method by measuring recovery from adaptation. Perceptual odor adaptation was measured by estimating psychophysical detection thresholds in a group of college-aged student volunteers (N = 20; 12 females, eight males) for a self-adapting odorant, vanilla extract. To induce adaptation, the time between the onset of the adapting odorant and the onset of the target odorant was systematically varied. By first quantifying adaptation, recovery of sensitivity could therefore be investigated by using different time points following the termination of the adapting odorant. Consistent with our previous work, thresholds estimated in the presence of the simultaneous adapting odorant were significantly increased, reflecting a decrease in sensitivity due to adaptation. Conversely, approximately 100 ms following termination of the adapting stimulus (the briefest delay tested), sensitivity began to rapidly recover. Nevertheless, some residual adaptation was evident at the longest offset delay of 500 ms. These findings suggest that the recovery from adaptation proceeds at least as rapidly as the onset of adaptation, a finding that is consistent with physiological evidence from olfactory receptors. These data also suggest the effectiveness of this new odorant paradigm in characterizing the temporal characteristics underlying these critical olfactory mechanisms.     

The moderating influence of socio‐demographic factors on the relationship between consumer psychographics and the attitude towards private label brands

This study examines the moderating influence of socio‐demographic variables (gender, age, education, income and family size) on the relationship between psychographic measures (general deal proneness, price‐related deal proneness, end‐of‐aisle display proneness, impulsiveness, smart‐shopper self‐perceptions and brand loyalty) and consumers' attitude towards private label brands. The proposed hypotheses are tested by collecting data at three different British supermarkets and assessed using structural equation modelling. The study reveals findings contrary to the prevailing views about consumer psychographics and socio‐demographics, including the following: (i) the significance of deal proneness among high‐income consumers; (ii) the end‐of‐aisle display proneness among older, high‐income and highly educated consumers; and (c) the relationship between impulsiveness and brand attitude among low‐income and less‐educated consumers. The study also provides multiple insights relating to psycho‐demographic targeting and display strategies. Copyright © 2013 John Wiley & Sons, Ltd.     

Analyzing the multiple functions of stereotypical behavior for students with autism: implications for assessment and treatment

We studied behavioral functions associated with stereotypical responses for students with autism. In Study 1, analogue functional analyses (attention, demand, no-attention, and recreation conditions) were conducted for 5 students. Results suggested that stereotypy was multiply determined or occurred across all assessment conditions. For 2 students, stereotypy was associated with positive and negative reinforcement and the absence of environmental stimulation. For 2 other students, stereotypy occurred at high levels across all experimental conditions. For the 5th student, stereotypy was associated with negative reinforcement and the absence of environmental stimulation. In Study 2, the stereotypy of 1 student was further analyzed on a function-by-function basis. Within a concurrent-schedules procedure, alternative responses were taught to the student using functional communication training. The results of Study 2 showed that similar topographies of stereotypy, based on qualitatively different reinforcers, were reduced only when differential reinforcement contingencies for alternative forms of communication were implemented for specific response-reinforcer relations. Our results suggest that the causes of stereotypy for students with autism are complex and that the presumed association between response topography and behavioral function may be less important than previously realized.     

The quest for generalizations over consonants: Asymmetries between consonants and vowels are not the by-product of acoustic differences

Consonants and vowels may play different roles during language processing, consonants being preferentially involved in lexical processing, and vowels tending to mark syntactic constituency through prosodic cues. In support of this view, artificial language learning studies have demonstrated that consonants (C) support statistical computations, whereas vowels (V) allow certain structural generalizations. Nevertheless, these asymmetries could be mere by-products of lower level acoustic differences between Cs and Vs, in particular the energy they carry, and thus their relative salience. Here we address this issue and show that vowels remain the preferred targets for generalizations, even when consonants are made highly salient or vowels barely audible. Participants listened to speech streams of nonsense CVCVCV words, in which consonants followed a simple ABA structure. Participants failed to generalize this structure over sonorant consonants (Experiment 1), even when vowel duration was reduced to one third of that of consonants (Experiment 2). When vowels were eliminated from the stream, participants showed only a marginal evidence of generalizations (Experiment 4). In contrast, participants readily generalized the structure over barely audible vowels (Experiment 3). These results show that different roles of consonants and vowels cannot be readily reduced to acoustical and perceptual differences between these phonetic categories.     

Effects of consumer psychographics and store characteristics in influencing shopping value and store switching

The research examines the impact of psychographic variables and store characteristics on utilitarian and hedonic shopping value. The findings demonstrate the direct influence of deal proneness and normative interpersonal influences on personal shopping value. Moreover, the study also captures the influence of several store characteristics, such as assortment, after sales service and ambience. The significant influence of shopping value in reducing store switching is also noteworthy. This study also provides evidence relating to how retailer‐controlled variables can influence consumer‐derived shopping value. Results show how each store environment factor influences consumers' overall shopping value and thereby provide an avenue to make strategic adjustments, which in turn can generate a better consumer experience and increased value. The study builds on and extends the previous work carried out relating to antecedents of shopping value by looking at the simultaneous influence of consumer‐level factors as well as retailer‐managed factors. Moreover, the study provides further evidence regarding how shopping value can lessen the dire impact of consumer defection at retail store level. Copyright © 2013 John Wiley & Sons, Ltd.     

An interaction between prosody and statistics in the segmentation of fluent speech

Sensitivity to prosodic cues might be used to constrain lexical search. Indeed, the prosodic organization of speech is such that words are invariably aligned with phrasal prosodic edges, providing a cue to segmentation. In this paper we devise an experimental paradigm that allows us to investigate the interaction between statistical and prosodic cues to extract words from a speech stream. We provide evidence that statistics over the syllables are computed independently of prosody. However, we also show that trisyllabic sequences with high transition probabilities that straddle two prosodic constituents appear not to be recognized. Taken together, our findings suggest that prosody acts as a filter, suppressing possible word-like sequences that span prosodic constituents.
