How Word Familiarity Facilitates Visual Search for Verbal Material

Two experiments assessed the impact of word familiarity on visual search for phrases. Participants' eye movements were recorded while they memorized target phrases and then searched for them within more or less similar phrases. The phrases were written with either familiar or unfamiliar, neuroscience‐specific vocabulary. Most participants did not search for the target by reading lines in a systematic way but scanned the first words of phrases to identify those beginning with the same words as the target. Visual search for unfamiliar target phrases was associated with an increase in the number of non‐target phrases that were scanned. The only search phase during which fixation durations depended on word familiarity was the final recognition of the target phrase. Hence, the data support a model of search within menu‐like displays in which searchers primarily rely on fast, visual match mechanisms and engage in reading‐like processing only during the critical decision‐making phase.

Hunger and Social Motivation: Hungry People are Less Interested in Social Activities than Satiated People

College students (N = 207) were asked their level of interest in sex, dating, and friendship affiliation before or after eating dinner at a dining hall. The threat of hunger before dinner was predicted to make participants focus on satisfying this need and therefore be less interested in social activities, compared to participants after dinner who were not hungry. Consistent with predictions, hungry males and females were less interested in sex, dating, and hanging out with friends compared to individuals who had just eaten. Results are considered in the context of motivation theory and recent research findings in the areas of physical attraction and social inclusion.     

And the Beat Goes On: Popular Billboard Song Beats Per Minute and Key Signatures Vary with Social and Economic Conditions

The beats per minute and key signatures of popular Billboard songs from 1955 to 2008 were investigated along with changes in the social and economic conditions of the USA, in accordance with the Environmental Security Hypothesis. Slower pop songs and songs in less common keys are generally more reflective and serious, whereas faster pop songs and songs in common keys are generally more celebratory and fun. Consistent with theory predictions, songs with more beats per minute and in common key signatures were most popular in social and economic good times and songs with less beats per minute and in less common key signatures were most popular during social and economic bad times. Environmental conditions appear to influence tempo and key preferences of popular music.     

Physiological and psychological impacts on male medical interns during on-call duty

This study aimed to explore the physiological and psychological impacts on male medical interns during on-call duty (OCD). A prospective study of 13 medical interns was carried out using repeated testing during an on-call internal medicine and a duty-free course. There are 10 OCDs per month and each duty is composed of 33.5 consecutive work hours followed by 2 duty-free days for a time period of 3 months. Spectral analysis of R-R intervals was performed to evaluate the participants' heart rate variability. Among the three main spectral components distinguished, a high-frequency (HF) component of 0.15-0.4 Hz and a low-frequency component (LF) of 0.04-0.15 Hz were analyzed. The ratio of LF and HF (LF/HF) was also calculated. Reduced LF/HF, which suggests reduced cardiac sympathetic modulation, was found during duty night work. Increased HF was identified during the first sleep after OCD, which corresponded to the sleepiness scales. The OCD causes temporary emotional influence by the findings of higher anxiety and depression scores. In addition, inattention and impulsiveness, as represented by the continuous performance test score and lower nocturnal sympathetic modulation, were found, which indicated the differences between the internal medicine course and duty-free course. Our study suggests that 10 stressful on-call duties monthly result in reduced sympathetic modulation during duty night work, high anxiety and depression state, and a persistent inattention.

How We See Us: An Examination of Factors Shaping the Appraisal of Stereotypical Media Images of Black Women among Black Adolescent Girls

The presence of stereotypical images of Black women in media has been well-documented throughout the literature. Existing evidence has indicated that these images contribute to a wide range of negative psychological and behavioral consequences for Black women and girls including decreased self-esteem, poorer interpersonal relationships and adverse mental health. However, despite the prevalence of stereotypical portrayals of Black women perpetuated in the media, evidence suggests that many Black adolescent girls are often resilient to the media’s effects. Prior research contends that this may be due to the individual’s appraisal of these images suggesting a need to investigate individual difference factors that may serve to shape appraisal. The current study is an examination of the relationship between exposure to stereotypical media images and appraisal in a sample of 66 adolescent Black girls. It was hypothesized that increased exposure to stereotypical media images of Black women would be associated with a negative appraisal of these images and that the relationship between frequency of exposure and appraisal would be moderated by racial identity. Results indicated that more frequent exposure to these images was in fact associated with a more negative appraisal and this relationship was moderated by racial identity.

     

Sympathy,Interpersonal Awareness and Acknowledgment

According to a popular thought, sympathy is an epistemic phenomenon: in sympathizing with others we come to be aware of them as fellow sentient beings. This view–which I call the Epistemic View–effectively characterizes sympathy as a form of social cognition. In this paper, I will argue against the Epistemic View. As far as I can see, this view radically misconstrues the way sympathy is directed at others. I will at the same time provide some material for, and motivate, an alternative proposal according to which the primary significance of sympathy is practical rather than epistemic. On this account, sympathy is a form of interpersonal acknowledgment rather than interpersonal awareness.

Degrading phonetic information affects matching of audiovisual speech in adults,but not in infants

Infants and adults are well able to match auditory and visual speech, but the cues on which they rely (viz. temporal, phonetic and energetic correspondence in the auditory and visual speech streams) may differ. Here we assessed the relative contribution of the different cues using sine-wave speech (SWS). Adults (N = 52) and infants (N = 34, age ranged in between 5 and 15 months) matched 2 trisyllabic speech sounds (‘kalisu’ and ‘mufapi’), either natural or SWS, with visual speech information. On each trial, adults saw two articulating faces and matched a sound to one of these, while infants were presented the same stimuli in a preferential looking paradigm. Adults’ performance was almost flawless with natural speech, but was significantly less accurate with SWS. In contrast, infants matched the sound to the articulating face equally well for natural speech and SWS. These results suggest that infants rely to a lesser extent on phonetic cues than adults do to match audio to visual speech. This is in line with the notion that the ability to extract phonetic information from the visual signal increases during development, and suggests that phonetic knowledge might not be the basis for early audiovisual correspondence detection in speech.     

Compensatory and non‐compensatory multidimensional randomized item response models

Randomized response (RR) models are often used for analysing univariate randomized response data and measuring population prevalence of sensitive behaviours. There is much empirical support for the belief that RR methods improve the cooperation of the respondents. Recently, RR models have been extended to measure individual unidimensional behaviour. An extension of this modelling framework is proposed to measure compensatory or non‐compensatory multiple sensitive factors underlying the randomized item response process. A confirmatory multidimensional randomized item response theory model (MRIRT) is proposed for the analysis of multivariate RR data by modelling the response process and specifying structural relationships between sensitive behaviours and background information. A Markov chain Monte Carlo algorithm is developed to estimate simultaneously the parameters of the MRIRT model. The model extension enables the computation of individual true item response probabilities, estimates of individuals’ sensitive behaviour on different domains, and their relationships with background variables. An MRIRT analysis is presented of data from a college alcohol problem scale, measuring alcohol‐related socio‐emotional and community problems, and alcohol expectancy questionnaire, measuring alcohol‐related sexual enhancement expectancies. Students were interviewed via direct or RR questioning. Scores of alcohol‐related problems and expectancies are significantly higher for the group of students questioned using the RR technique. Alcohol‐related problems and sexual enhancement expectancies are positively moderately correlated and vary differently across gender and universities.
