Neurofeedback training with virtual reality for inattention and impulsiveness.

In this research, the effectiveness of neurofeedback, along with virtual reality (VR), in reducing the level of inattention and impulsiveness was investigated. Twenty-eight male participants, aged 14-18, with social problems, took part in this study. They were separated into three groups: a control group, a VR group, and a non-VR group. The VR and non-VR groups underwent eight sessions of neurofeedback training over 2 weeks, while the control group just waited during the same period. The VR group used a head-mounted display (HMD) and a head tracker, which let them look around the virtual world. Conversely, the non-VR group used only a computer monitor with a fixed viewpoint. All participants performed a continuous performance task (CPT) before and after the complete training session. The results showed that both the VR and non-VR groups achieved better scores in the CPT after the training session, while the control group showed no significant difference. Compared with the other groups, the VR group presented a tendency to get better results, suggesting that immersive VR is applicable to neurofeedback for the rehabilitation of inattention and impulsiveness.     

Influences of multiple spatial stimulus and response codes on orthogonal stimulus—response compatibility

When up-down stimuli are mapped to left-right responses, an up-right/down-left mapping advantage is found that is modified by response eccentricity and hand posture. These effects can be attributed to correspondence of asymmetric stimulus and response codes formed relative to multiple reference frames. We examined the influence of stimulus-set location on these orthogonal stimulus-response compatibility (SRC) effects. In Experiment 1, the stimulus set appeared in the upper or lower display positions. A spatial code for stimulus-set location was formed, producing Simon-type response eccentricity and hand posture effects, but this code had no influence on the coding of the relevant stimuli. In Experiment 2, the stimulus set appeared in the left, center, or right positions relative to the response location, which also varied, to dissociate the effects of response location, relative to the stimulus display and body midline. The former factor influenced the orthogonal SRC effect for both unimanual switch movements and bimanual keypresses, and the latter factor influenced the effect for only unimanual switch movements. Stimulus-set location causes orthogonal Simon-type effects when varied along the stimulus dimension and provides a referent for response coding when varied along the response dimension.     

An interest‐based intervention package to increase peer social interaction in young children with autism spectrum disorder

The literature suggests that children with autism spectrum disorder (ASD) educated in inclusive settings generally do not interact with typically developing classmates during social activities. This study assessed whether an intervention package consisting of interest‐based structured play activities involving adult instruction, modeling, and response to child questions would result in an increase in social interaction with typically developing peers. A multiple baseline design across four participants with an embedded reversal was used to demonstrate the effects of the intervention on social interaction during structured play sessions. Initiations, responses, and interactive play increased for all participants. Generalization to novel peers was observed, and treatment gains were maintained during 6‐week follow‐up sessions. Recommendations for practitioners working with children with ASD in inclusive settings and potential areas of future research are discussed.     

Pilot study of hormone replacement therapy and menopausal symptoms, depression, and quality of life in Korean climacteric women

This cross-sectional survey compared scores on the Menopausal Symptoms Index, Depression, and the Quality of Life for 65 Korean climacteric women receiving regular hormone replacement therapy (M age=52.8 yr., SD=6.3) and 70 Korean climacteric patients not receiving such therapy (M age =51.6 yr., SD=7.1). Depression scores were positively correlated with the Menopausal Symptoms Index in both groups (r = .58 in the Therapy group and r = .50 in the Control group) and negatively correlated with scores for Quality of Life (r = -.48 in the Therapy group and r = -.68 in the Control group). Scores on the Menopausal Symptoms Index were negatively correlated with ratings of Quality of Life in both groups (r = -.53 in the Therapy group and r = -.45 in the Control group). These results suggest that hormone replacement therapy is associated with reduced Depression scores and higher Quality of Life scores in this sample of Korean climacteric women.     

Mechanisms underlying dependencies of performance on stimulus history in a two-alternative forced-choice task

In choice reaction time tasks, response times and error rates demonstrate differential dependencies on the identities of up to four stimuli preceding the current one. Although the general profile of reaction times and error rates, when plotted against the stimulus histories, may seem idiosyncratic, we show that it can result from simple underlying mechanisms that take account of the occurrence of stimulus repetitions and alternations. Employing a simple connectionist model of a two-alternative forcedchoice task, we explored various combinations of repetition and alternation detection schemes in an attempt to account for empirical results from the literature and from our own studies. We found that certain combinations of the repetition and the alternation schemes provided good fits to the data, suggesting that simple mechanisms may serve to explain the complicated but highly reproducible higher order dependencies of task performance on stimulus history.     

Virtual brand experience in digital reality advertising: Conceptualization and measurement

This study explores virtual brand experience (VBE), a new type of brand experience, and develops a corresponding measurement scale. The VBE scale includes five dimensions (social, intellectual, sensory, behavioral, and affective), and is validated by examining the sequential relationships among VBE, brand engagement, and consumer responses to digital reality ads. A path model shows that the social dimension is the most influential factor affecting consumer engagement with brands featured in digital reality ads. The findings indicate that VBE, given its multisensory interactive nature, can be considered equivalent to a direct experience despite it being a mediated one (i.e., indirect experience). This study contributes to the digital marketing literature and highlights the practical benefits of digital reality as a compelling branding tool in digital marketing.     

A stochastic multidimensional scaling vector threshold model for the spatial representation of “pick any/n” data

This paper presents a new stochastic multidimensional scaling vector threshold model designed to analyze pick any/n choice data (e.g., consumers rendering buy/no buy decisions concerning a number of actual products). A maximum likelihood procedure is formulated to estimate a joint space of both individuals (represented as vectors) and stimuli (represented as points). The relevant psychometric literature concerning the spatial treatment of such binary choice data is reviewed. The nonlinear probit type model is described, as well as the conjugate gradient procedure used to estimate parameters. Results of Monte Carlo analyses investigating the performance of this methodology with synthetic choice data sets are presented. An application concerning consumer choices for eleven competitive brands of soft drinks is discussed. Finally, directions for future research are presented in terms of further applications and generalizing the model to accommodate three-way choice data.     

Quality of Jobs for Female Workers: A Comparative Study of South Korea and Australia

This study conducts a comparative analysis regarding the quality of job in Australia and South Korea on the basis of ordered logit model using two countries’ household data sets during 2003–2009. We compose the quality of job into various subgroups by combining hourly wage, job security and working hours, and verify that despite having similar Affirmative Action (AA) systems in the two countries, Australian women are more likely to work in jobs with higher quality compared to South Korean women subject to the loose incentive operation of AA.     

The Acuity for Numerosity (but Not Continuous Magnitude) Discrimination Correlates with Quantitative Problem Solving but Not Routinized Arithmetic

Approximate number sense (ANS) acuity refers to the ability to non-symbolically recognize, estimate and operate upon large numerosities. ANS acuity has been reported to be correlated with math achievement in children and adolescents. However, reports of this relationship in adults have been inconsistent. The present study aimed to resolve the inconsistency in the relationship between adults’ ANS acuity and math achievement by contrasting between different kinds of mathematical problem solving. We hypothesized that the correlation between ANS acuity mathematical performance would be stronger when deep quantitative processing is required during problem solving. In Experiment 1, ANS acuity was correlated with Mathematical Reasoning but not Directed Calculation performance. In Experiment 2, ANS acuity was correlated with Two-digit Subtraction (but not Addition) performance only when Regrouping (i.e., borrowing) was required. The results from two experiments demonstrated that ANS acuity was correlated with mathematical performance only when problem solving involved effortful, quantitative processing that goes beyond automatized, routinized arithmetic. In addition, ANS acuity was distinguishable from Area acuity regarding its unique relationship with math achievement, which was unconfounded by the influence of demographic variables and fluid intelligence. Overall, the present results help resolve the inconsistency in previous reports of the correlation between ANS acuity and math achievement in adults.
