Explaining Differences in Philanthropic Behavior Between Christians,Muslims, and Hindus in the Netherlands

Using survey data from the Netherlands, we find that Muslims have relatively high levels of religious philanthropic behavior and relatively low levels of secular philanthropic behavior, whereas Hindus have relatively low levels of religious philanthropic behavior and higher levels of secular philanthropic behavior. Results indicate that the community explanation and the conviction explanation of the relationship between religion and philanthropic behavior are both valid to some extent when it comes to differences in philanthropic behavior between Christians, Muslims, and Hindus. In addition, we find a relationship between group orientation in worship rituals on the relation between religion and philanthropic behavior. The more group-oriented the worship rituals, the stronger the relation between religion and philanthropic behavior. The results suggest that Durkheim’s theory (La Suicide: Etude de Sociologie. Presses Universitaires de France, Paris, 1897) may only be valid in a Christian context.     

Mental states inside out: Switching costs for emotional and nonemotional sentences that differ in internal and external focus

Mental states—such as thinking, remembering, or feeling angry, happy, or dizzy—have a clear internal component. We feel a certain way when we are in these states. These internal experiences may be simulated when people understand conceptual references to mental states. However, mental states can also be described from an “external” perspective, for example when referring to “smiling.” In those cases, simulation of visible outside features may be more relevant for understanding. In a switching costs paradigm, we presented semantically unrelated sentences describing emotional and nonemotional mental states while manipulating their internal or external focus. The results show that switching costs occur when participants shift between sentences with an internal and an external focus. This suggests that different forms of simulation underlie understanding these sentences. In addition, these effects occurred for emotional and nonemotional mental states, suggesting that they are grounded in a similar way—through the process of simulation.     

A forced-attention dichotic listening fMRI study on 113 subjects

We report fMRI and behavioral data from 113 subjects on attention and cognitive control using a variant of the classic dichotic listening paradigm with pairwise presentations of consonant-vowel syllables. The syllable stimuli were presented in a block-design while subjects were in the MR scanner. The subjects were instructed to pay attention to and report either the left or right ear stimulus. The hypothesis was that paying attention to the left ear stimulus (FL condition) induces a cognitive conflict, requiring cognitive control processes, not seen when paying attention to the right ear stimulus (FR condition), due to the perceptual salience of the right ear stimulus in a dichotic situation. The FL condition resulted in distinct activations in the left inferior prefrontal gyrus and caudate nucleus, while the right inferior frontal gyrus and caudate were activated in both the FL and FR conditions, and in a non-instructed (NF) baseline condition.     

The contribution of functional near-infrared spectroscopy (fNIRS) to the presurgical assessment of language function in children

Before performing neurosurgery, an exhaustive presurgical assessment is required, usually including an investigation of language cerebral lateralization. Among the available procedures, the intracarotid amobarbital test (IAT) was formerly the most widely used. However, this procedure has many limitations: it is invasive and potentially traumatic, especially for children. To overcome these limitations, neuroimaging techniques such as functional magnetic resonance imaging (fMRI) have been used. Again, these methods are difficult to use with children, who must remain motionless during data acquisition. Functional near-infrared spectroscopy (fNIRS) is a noninvasive functional imaging technique that is easily applied to pediatric and cognitively limited patients. It has been used recently in epileptic children for presurgical assessment of expressive and receptive language brain lateralization. The aim of this review is to present the contribution of fNIRS to the presurgical assessment of language function in children with neurological diseases.     

Correlates of personality trait levels and their changes in very old age: The Lothian Birth Cohort 1921

We tested the associations between individual differences in the Big Five personality traits and their changes over the ninth decade of life and levels of and changes in cognitive functioning, physical fitness, and everyday functioning. Besides mean-level changes in personality traits, there were significant individual differences in their rates of change between ages 81 and 87. The changes in the Big Five traits were not strongly intercorrelated, suggesting little common influence on personality change. Lower IQ at age 79 predicted lower Intellect and higher Extraversion, and more decline in Conscientiousness from ages 81 to 87. Also, decreases in physical fitness were associated with declines in Conscientiousness.     

ERP correlates of language-specific processing of auditory pitch feedback during self-vocalization

The present study investigated whether the neural correlates for auditory feedback control of vocal pitch can be shaped by tone language experience. Event-related potentials (P2/N1) were recorded from adult native speakers of Mandarin and Cantonese who heard their voice auditory feedback shifted in pitch by −50, −100, −200, or −500 cents when they sustained the vowel sound /u/. Cantonese speakers produced larger P2 amplitudes to −200 or −500 cents stimuli than Mandarin speakers, but this language effect failed to reach significance in the case of −50 or −100 cents. Moreover, Mandarin speakers produced shorter N1 latencies over the left hemisphere than the right hemisphere, whereas Cantonese speakers did not. These findings demonstrate that neural processing of auditory pitch feedback in vocal motor control is subject to language-dependent neural plasticity, suggesting that cortical mechanisms of auditory-vocal integration can be shaped by tone language experience.     

Bullying in Classrooms: Participant Roles From a Social Network Perspective

The aim of this research was to investigate if and how the group process of bullying can be examined using a social network perspective. In two studies, bullying was investigated using a social network version of the participant‐role questionnaire. Study 1 explored the social network structure of one classroom in detail. The findings provide evidence that ingroup and outgroup effects are important in explaining the group process of bullying, and shed new light on defending, suggesting that not only victims are defended. In line with Study 1, Study 2, using data from 494 children in 25 elementary school classes (M age = 10.5), revealed that victims as well as bullies were defended by their ingroup members. The social network perspective can be integrated in antibullying interventions by using it to inform teachers about the positive and negative relations among students, and the group structure of the classroom.

A randomized control trial of integrated care for families managing infant colic

This article presents a randomized clinical trial examining the effectiveness of a unique model of integrated care for the treatment of infant colic. Families seeking help for infant colic were randomized to either the family‐centered treatment (TX; n = 31) or standard pediatric care (SC; n = 31). All parents completed 3 days of Infant Behavior Diaries (Barr et al., 1998) and the Colic Symptom Checklist (Lester, 1997 ), Beck Depression Inventory (Beck & Steer, 1984 ), and Parenting Stress Index 3rd ed.‐SF (Abidin, 1995 ). TX families were seen three times by a pediatrician and a mental health clinician within 1, 2, and 6 weeks of baseline data. TX families received individualized treatment plans addressing problem areas of sleep, feeding, routine, and family mental health. SC families were seen only by their own healthcare provider. All families were visited at home by a research assistant to retrieve data at 2, 6, and 10 weeks after baseline. Family‐based treatment accelerated the rate of reduction of infant crying faster than did standard pediatric care. Infants in the TX group had more hours of sleep at 2 weeks posttreatment and spent less time feeding at 2, 6, and 10 weeks posttreatment than did SC infants. Results indicate that individualized family‐based treatment reduces infant colic more rapidly than does standard pediatric care.     

Differential recognition of pitch patterns in discrete and gliding stimuli in congenital amusia: evidence from Mandarin speakers

This study examined whether "melodic contour deafness" (insensitivity to the direction of pitch movement) in congenital amusia is associated with specific types of pitch patterns (discrete versus gliding pitches) or stimulus types (speech syllables versus complex tones). Thresholds for identification of pitch direction were obtained using discrete or gliding pitches in the syllable /ma/ or its complex tone analog, from nineteen amusics and nineteen controls, all healthy university students with Mandarin Chinese as their native language. Amusics, unlike controls, had more difficulty recognizing pitch direction in discrete than in gliding pitches, for both speech and non-speech stimuli. Also, amusic thresholds were not significantly affected by stimulus types (speech versus non-speech), whereas controls showed lower thresholds for tones than for speech. These findings help explain why amusics have greater difficulty with discrete musical pitch perception than with speech perception, in which continuously changing pitch movements are prevalent.
