The Induction of Self-Reliance: An Experimental Study of Independence in the Face of Failure*

The development of dependency, rather than autonomy, in professional and paraprofessional helping relationships represents a practical and theoretical problem. In the present research an attempt is made experimentally to examine this issue from the viewpoint of the self-perception hypothesis. From this perspective, immersion in the successful helping dyad was expected to foster an increased belief in self as other-reliant, and, through cognitive balance, a lessened belief in self as self-reliant. The fiidings indicate that such different dimensions of help as intensity, duration, and choice variously affect these attributions to self, and that these attributions in turn affect the strength of behavioral independence when failure is encountered outside the helping dyad. Some practical and theoretical implications are discussed concerning the role of induction from self-performance in mapping self-related beliefs.     

Ultrafast scene detection and recognition with limited visual information

Humans can detect target colour pictures of scenes depicting concepts like picnic or harbour in sequences of six or 12 pictures presented as briefly as 13?ms, even when the target is named after the sequence. Such rapid detection suggests that feedforward processing alone enabled detection without recurrent cortical feedback. There is debate about whether coarse, global, low spatial frequencies (LSFs) provide predictive information to high cortical levels through the rapid magnocellular (M) projection of the visual path, enabling top-down prediction of possible object identities. To test the “Fast M” hypothesis, we compared detection of a named target across five stimulus conditions: unaltered colour, blurred colour, greyscale, thresholded monochrome, and LSF pictures. The pictures were presented for 13–80?ms in six-picture rapid serial visual presentation (RSVP) sequences. Blurred, monochrome, and LSF pictures were detected less accurately than normal colour or greyscale pictures. When the target was named before the sequence, all picture types except LSF resulted in above-chance detection at all durations. Crucially, when the name was given only after the sequence, performance dropped and the monochrome and LSF pictures (but not the blurred pictures) were at or near chance. Thus, without advance information, monochrome and LSF pictures were rarely understood. The results offer only limited support for the Fast M hypothesis, suggesting instead that feedforward processing is able to activate conceptual representations without complementary reentrant processing.     

Empathizing and Systemizing (Un)justified Mediated Violence: Psychophysiological Indicators of Emotional Response

This article examines individual variability in empathizing and systemizing abilities (Baron-Cohen, 2003 Baron-Cohen, S. (2003). The essential difference: Men, women and the extreme male brain. London, UK: Penguin. [Google Scholar], 2009 Baron-Cohen, S. (2009). Autism: The empathizing &; systemizing (E–S) theory. Annals of the New York Academy of Sciences, 1156, 68–80.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) on emotional responses to mediated violence. It is predicted that these abilities influence feelings of distress and enjoyment while processing violent media and that they interact with the motives for aggressive behavior—whether the violence was justified or not. Psychophysiological measures of negative and positive valence activation and arousal were recorded for 90 participants while they were exposed to fourteen full-motion film clips that contained violence that was either justified or not by the narrative. Results show unjustified content led to greater physiological arousal and greater negative valence activation overall and to a significantly greater extent in highly empathetic viewers. Advantages of employing the empathizing—systemizing theory to mediated violence research are discussed.     

Who are your Neighbors? Neighbor Relationships and Subjective Well-Being in Japan

Supportive relationships with neighbors have been shown to positively predict indicators of subjective well-being. Using data from the 2010 Japanese General Social Survey, we examine how neighbor relationships predict subjective well-being. Japan presents an interesting case to examine this question when considering its highly institutionalized neighborhood associations. We find that controlling for the safety and amenity aspects of the neighborhood environment, supportive neighbor relationships significantly increase men and women’s life satisfaction, but such relationships have a significant positive effect only on men’s happiness. The effects of neighborhood relationships on life satisfaction and happiness are significantly larger for men. Moreover, we find that the social and safety aspects of the neighborhood reinforce each other to increase life satisfaction also only for men. Implications of the gendered pattern of these results are discussed for future research on the association between neighbor relationships and subjective well-being in Japan and beyond.

Extra‐Role Behavior among Mexican Employees: The Impact of LMX,Group Acceptance,and Job Attitudes

The current field study took place within a Mexican work setting, consisting of 100 white‐collar employees representing a variety of professional job categories. The study investigated the direct effect of the supervisor–employee relationship (leader–member exchange) quality and group acceptance on employees' propensity to engage in activities beyond their formal work roles (extra‐role behavior). The mediating influences of the employees' job satisfaction level and organizational commitment were also taken into consideration when accounting for extra‐role behavior. Results suggest that relationships Mexican employees share with their supervisor have a direct impact on their extra‐role behavior. Social exchange, key to both extra‐role behavior and leader–member exchange, is proposed as the operating mechanism associating the two constructs. Results also indicate that organizational commitment plays a partial mediating role between leader–member exchange and extra‐role behavior.     

Religious Affiliation, Ethnicity, and Child Mortality in Chiapas, México

We investigate whether there is a relationship between religious affiliation and child mortality among indigenous and nonindigenous groups in Chiapas, México. Our analysis relies on Brass-type estimates of child mortality by ethnicity and religious affiliation and multivariate analyses that adjust for various socioeconomic and demographic factors. The data are from the 2000 Mexican Census 10 percent sample. Among indigenous people, Presbyterians have lower rates of child mortality than Catholics. However, no significant differentials are found in child mortality by religious affiliation among nonindigenous people. The indigenous health ministry of the Presbyterian Church and the social and cultural transformations that tend to accompany religious conversion may have an impact on child survival among disadvantaged populations such as the indigenous people in Chiapas.     

Enhanced cognitive activity--over and above social or physical activity--is required to protect Alzheimer's mice against cognitive impairment, reduce Abeta deposition, and increase synaptic immunoreactivity

Although social, physical, and cognitive activities have each been suggested to reduce the risk of Alzheimer's disease (AD), epidemiologic studies cannot determine which activity or combination of activities is most important. To address this question, mutant APP transgenic AD mice were reared long-term in one of four housing conditions (impoverished, social, social+physical, or complete enrichment) from 1(1/2) through 9 months of age. Thus, a stepwise layering of social, physical, and enhanced cognitive activity was created. Behavioral evaluation in a full battery of sensorimotor, anxiety, and cognitive tasks was carried out during the final 5 weeks of housing. Only AD mice raised in complete enrichment (i.e., enhanced cognitive activity) showed: (1) protection against cognitive impairment, (2) decreased brain beta-amyloid deposition, and (3) increased hippocampal synaptic immunoreactivity. The protection provided by enhanced cognitive activity spanned multiple cognitive domains (working memory, reference learning, and recognition/identification). Cognitive and neurohistologic benefits of complete enrichment occurred without any changes in blood cytokine or corticosterone levels, suggesting that enrichment-dependent mechanisms do not involve changes in the inflammatory response or stress levels, respectively. These results indicate that the enhanced cognitive activity of complete enrichment is required for cognitive and neurologic benefit to AD mice-physical and/or social activity are insufficient. Thus, our data suggest that humans who emphasize a high lifelong level of cognitive activity (over and above social and physical activities) will attain the maximal environmental protection against AD.     

Beliefs and data on the relationship between consistency and accuracy of eyewitness testimony

Two studies concerned with consistency and accuracy of eyewitness testimony were conducted. In Study 1 potential jurors indicated the degree to which they considered that various witness on‐stand behaviours indicated testimonial accuracy. Witness statements that were inconsistent with previous statements were considered to be the strongest indicators of inaccuracy. Study 2 examined the relationship between consistency and accuracy of testimony. Witnesses viewed a film of a robbery and were interviewed twice (2 weeks apart) about the crime in a 4 (interview format)×2 (interview occasion) design. Regardless of whether consistency was operationalised in terms of direct contradictions between interviews, or degree of agreement on detail across interviews, no more than 10% of the variance in overall accuracy rate was explained by any individual measure. Number of contradictions and overall agreement between interviews did, however, make additive contributions to prediction of overall accuracy. Also, higher correlations between contradiction‐based consistency measures and interview two accuracy rate were detected. Neither consistency nor accuracy for specific testimonial dimensions were predictive of accuracy on the other dimensions, or overall accuracy. Copyright © 1999 John Wiley & Sons, Ltd.
