Butch–femme identity and empathizing–systemizing cognitive traits in Chinese lesbians and bisexual women

Previous studies documented that butches showed a masculine profile and femmes showed a feminine profile in gender roles. This study examines the association between butch or femme lesbian identity and empathizing–systemizing (E–S) cognitive styles among 588 lesbian and bisexual women from multiple cities in China. Empathizing and systemizing were assessed using two different abbreviated 8-item scales drawn from longer original scales. There were significant differences in systemizing among butch–femme identity, with butches scoring higher than femmes, but no significant differences in empathizing. The discrepancy in empathizing–systemizing scores reflects individual differences in dispositional cognitive style. A higher proportion of femmes exhibited an E > S cognitive profile, while a higher proportion of butches exhibited an S > E cognitive profile. Sexual stereotyping based on masculinity/femininity, or biology, may be related to butch–femme difference in cognitive style. In studies on sexual orientation, researchers should pay more attention to butch–femme subgroup differences among lesbians.     

Emergent Motivation to Read in Prekindergarten Children

This study aimed to develop and validate a measure of emergent reading motivation designed for prekindergarten children, called the Emergent Reading Motivation Scale (ERMS). The development of the ERMS was to overcome the limitation that current existing reading motivation measures are not developmentally appropriate for young children. Fifty-six native-English speaking children who were enrolled in a prekindergarten program participated in the study. The ERMS had 17 items that were drawn from reading self-concept, reading performance goal, and reading learning goal. The scale was administered through two sock puppets. For each item, the puppets represented contrasting behaviors regarding reading motivation. The children were asked to choose the puppet that was most like themselves. Results suggested that the ERMS is an age-appropriate reading motivation measure for prekindergarten children and has a three-factor structure as assumed even though its internal consistency is moderate and is of limited predictive power of emergent literacy skills.     

Exposure to violence reduces empathetic responses to other’s pain

Past researches showed that empathy for pain not only triggers a resonance mechanism between other and self, but also is modulated by contextual factors. Using functional magnetic resonance imaging, the present study demonstrated that short-term media violence exposure reduced both pain ratings and also the activation of anterior insula and anterior mid-cingulate cortex to other’s pain. Thus, violence exposure modulated empathic responses to other’s pain based on a physiological desensitization.     

Multiple phase transitions in CuO

Electrical resistivity, thermoelectric power, magnetic susceptibility and calorimetric measurements were carried out on a single crystal of CuO. In addition the two known antiferromagnetic transitions between 210K and 230K, a new phase transition around 160K was found in CuO. The experimental results show that this new transition is related to changes in the electronic state of CuO.     

Cognition and Emotion in TV Message Processing: How Valence,Arousing Content,Structural Complexity,and Information Density Affect the Availability of Cognitive Resources

This paper examines whether emotional message content alters the effects of structural complexity and information density on available resources, measured by secondary task reaction times (STRTs), and message encoding, measured by audio recognition. In addition, hypotheses relating motivational activation and resource availability based on the motivational activation concepts of positivity offset (greater appetitive activation in a neutral environment) and negativity bias (faster aversive activation) influence are tested. Results replicate previous research supporting the contention that STRTs measure available resources. In addition, they show that the basic pattern of STRTs and recognition as a function of allocated and required resources is relatively consistent regardless of emotional content of the message. Emotion appears to function as a constant, increasing both resource allocation and resources required. Finally, these data provide some initial support for predicted relationships between motivational activation and resource allocation based on the constructs of positivity offset and negativity bias.     

Capturing and evaluating blinks from video-based eyetrackers

Blinks are related to several emotional states, and the present report describes a simple, reliable way to measure blinks from the video stream of an eye obtained during eyetracking, where the source of the eye video is a video camera attached to a head-mounted eyetracker. Computer vision techniques are employed to determine the moments that a blink starts and ends, for the purpose of calculating blink frequency and duration. The video is first processed to show blocks of eyelid and pupil movements, and is then analyzed for blink starts and ends. The moment of a blink start is reported when the eyelid starts to move quickly, exceeding a predetermined threshold. The end of a blink arises when the pupil size increases by less than a separate threshold. We observed several different blink patterns from different subjects, and our algorithm was designed to work for all of these patterns. We evaluated our algorithm by manually measuring the true blinks of five different subjects while they were eyetracked. To test the sensitivity and specificity of the algorithm, we employed a series of threshold values to plot the receiver operating characteristic curves. Using the best thresholds, we achieved excellent sensitivity (>90 %) and specificity (>99 %) over the five subjects. Potential applications of this research include real-time, nonintrusive, continuous and automated measurements of mental workload and other emotional states related to blink rates and durations.     

Nonselective access of English phonology in bi-scriptal Chinese–Korean visual word recognition

This study investigated the phonological processes with bilingual readers of Korean and Chinese. Three types of same–different matching between the prime and target were compared. The critical point was on whether the phonological information of English was activated automatically in a semantic judgment task involving only Korean and Chinese. The results showed that the latency of the conditions (S+P?, S?P? and S?P+) was significantly different; latencies in the S?P+ condition where there is no semantic but with phonological relations were slower than in the S?P? condition where there are neither semantic nor phonological relations. The implication for phonological recoding was discussed.     

Objective assessment of the functional role of spike train correlations using information measures

The functional role of correlations between neuronal spike trains remains strongly debated. This debate partly stems from the lack of a standardized analysis technique capable of accurately quantifying the role of correlations in stimulus encoding. We believe that information theoretic measures may represent an objective method for analysing the functional role of neuronal correlations. Here we show that information analysis of pairs of spike trains allows the information content present in the firing rate to be disambiguated from any extra information that may be present in the temporal relationships of the two spike trains. We validate and illustrate the method by applying it to simulated data with variable degrees of known synchrony, and by applying it to recordings from pairs of sites in the primary visual cortex of anaesthetized cats. We discuss the importance of information theoretic analysis in elucidating the neuronal mechanisms underlying object identification.     

家庭功能与大学生情绪表达性、孤独感的关系

通过问卷调查法和结构方程模型分析技术,探讨家庭功能与大学生情绪表达性、孤独感之间的关系,以及家庭功能的作用机制,即家庭功能能否通过情绪表达影响大学生孤独感。结果发现:(1)家庭功能对大学生情绪表达性、孤独感有显著预测作用,家庭亲密度或适应性水平高的大学生更倾向具有高的情绪表达性,更少的体验到亲情、爱情以及社交孤独感;(2)情绪表达性对大学生社交孤独感具有一定的预测作用,即大学生越乐于表达情绪,其社交孤独感就越少;(3)家庭功能既直接对社交孤独感产生影响,又通过情绪表达性间接影响社交孤独感,即情绪表达性在家庭功能与社交孤独感之间起部分中介作用。
