Seeking professional help: Etiology beliefs about mental illness across cultures

In the present study, the authors examined the contributions of cultural beliefs about the etiology of mental illness to the seeking of help from mental health professionals among college students in 4 cultural groups, European Americans, Chinese Americans, Hong Kong Chinese, and Mainland Chinese. Group differences were found in help-seeking history and likelihood, with European and Chinese Americans being more likely to seek help than Hong Kong and Mainland Chinese. Multiple-group path analysis showed that lay beliefs about causes of mental illness and prior help-seeking history significantly predicted help-seeking likelihood, which was related positively to environmental/hereditary causes but negatively to social-personal causes. Our findings demonstrate the importance of understanding help-seeking patterns within specific cultural contexts and the effects of Western influences on shaping help-seeking propensities.

The reading ability of good and poor temporal processors among a group of college students

In this study, we examined whether good auditory and good visual temporal processors were better than their poor counterparts on certain reading measures. Various visual and auditory temporal tasks were administered to 105 undergraduates. They read some phonologically regular pseudowords and irregular words that were presented sequentially in the same ("word" condition) and in different ("line" condition) locations. Results indicated that auditory temporal acuity was more relevant to reading, whereas visual temporal acuity was more relevant to spelling. Good auditory temporal processors did not have the advantage in processing pseudowords, even though pseudoword reading correlated significantly with auditory temporal processing. These results suggested that some higher cognitive or phonological processes mediated the relationship between auditory temporal processing and pseudoword reading. Good visual temporal processors did not have the advantage in processing irregular words. They also did not process the line condition more accurately than the word condition. The discrepancy might be attributed to the use of normal adults and the unnatural reading situation that did not fully capture the function of the visual temporal processes. The distributions of auditory and visual temporal processing abilities were co-occurring to some degree, but they maintained considerable independence. There was also a lack of a relationship between the type and severity of reading deficits and the type and number of temporal deficits.     

Validity of the Developmental Test of Visual-Motor Integration Supplemental Developmental Test of Visual Perception

Visual perceptual skills of school-age children are often assessed using the Supplemental Developmental Test of Visual Perception of the Developmental Test of Visual-Motor Integration. The study purpose was to consider the construct validity of this test by evaluating its scalability (interval level measurement), unidimensionality, differential item functioning, and hierarchical ordering of its items. Visual perceptual performance scores from a sample of 356 typically developing children (171 boys and 185 girls ages 5 to 11 years) were used to complete a Rasch analysis of the test. Seven items were discarded for poor fit, while none of the items exhibited differential item functioning by sex. The construct validity, scalability, hierarchical ordering, and lack of differential item functioning requirements were met by the final test version. Since 7 test items did not fit the Rasch analysis specifications, the clinical value of the test is questionable and limited.     

Adults who are more anxious and were anxiously attached as children report later first memories

Here, we examined retrospective reports of adults’ earliest autobiographical memory, the age of this report and whether the reported age was associated with exposure to early life adversity, current anxiety and childhood attachment. Across four studies, we found that reporting a later ‘earliest’ memory was associated with higher self-reported anxiety in both American (Studies 1, 2 and 4) and Australian (Study 3) samples. Furthermore, in Studies 2–4, we found that reporting a later earliest memory uniquely predicted anxiety when controlling for number of adverse childhood events (a risk factor for the development of anxiety). In Study 4, we established that this relation is partially mediated by childhood anxious attachment. Although we consistently demonstrated that later earliest memories were associated with current anxiety, we found little evidence for a relation between reported age at the time of earliest memory and childhood adversity. We also found no evidence of gender differences in the associations of interest. These results suggest that poorer memory of early childhood is associated with greater childhood anxious attachment and anxiety in adulthood. The implications of this work are discussed in terms of the adaptive nature of autobiographical memory and the development of a coherent life narrative.     

The visual light field

Human observers are sensitive to the '(physical) light field' in the sense that they have expectations of how a given object would appear if it were introduced in the scene in front of them at some arbitrary location. Thus the 'visual light field' is defined even in the 'empty space' between objects. In that sense the light field is akin to visual space considered as a 'container'. The visual light field at any given point can be measured in psychophysical experiments through the introduction of a suitable 'gauge object' at that position and letting the observer adjust the appearance of that gauge object (eg through suitable computer rendering) so as to produce a 'visual fit' into the scene. The parameters of the rendering will then be considered as the measurement result. We introduced white spheres as gauge objects at various locations in stereoscopically presented photographic scenes. We measured the direction ('direction of the light'), diffuseness ('quality of the light' as used by photographers and interior decorators), and intensity of the light field. We used three very different scenes, with very different physical light fields. The images were geometrically and photometrically calibrated, so we were in a position to correlate the observations with the physical 'ground truth'. We report that human observers are quite sensitive to various parameters of the physical light field and generally arrive at close to veridical settings, although a number of comparatively minor systematic deviations from veridicality can be noted. We conclude that the visual light field is an entity whose existence is at least as well defined as that of visual space, despite the fact that the visual light field hardly appears as prominently in vision science as it does in the visual arts.     

Medicare's search for effective obesity treatments: diets are not the answer

The prevalence of obesity and its associated health problems have increased sharply in the past 2 decades. New revisions to Medicare policy will allow funding for obesity treatments of proven efficacy. The authors review studies of the long-term outcomes of calorie-restricting diets to assess whether dieting is an effective treatment for obesity. These studies show that one third to two thirds of dieters regain more weight than they lost on their diets, and these studies likely underestimate the extent to which dieting is counterproductive because of several methodological problems, all of which bias the studies toward showing successful weight loss maintenance. In addition, the studies do not provide consistent evidence that dieting results in significant health improvements, regardless of weight change. In sum, there is little support for the notion that diets lead to lasting weight loss or health benefits.     

The contribution of rapid visual and auditory processing to the reading of irregular words and pseudowords presented singly and in contiguity

This study examined the relative involvement of rapid auditory and visual temporal resolution mechanisms in the reading of phonologically regular pseudowords and English irregular words presented both in isolation and in contiguity as a series of six words. Seventy-nine undergraduates participated in a range of reading, visual temporal, and auditory temporal tasks. The correlation analyses suggested a general timing mechanism across modalities. There were more significant correlations between the visual temporal measures and irregular word reading and between the auditory measures and pseudoword reading. Auditory gap detection predicted pseudoword reading accuracies. The low temporal frequency flicker contrast sensitivity measure predicted the accuracies of isolated irregular words and pseudowords presented in contiguity. However, when a combined speed-accuracy score was used, visible persistence at both low and high spatial frequencies and auditory gap detection were active in the reading of pseudowords presented in contiguity. Sensory processing skills in both visual and auditory modalities accounted for some of the variance in the reading performance of normal undergraduates, not just reading-impaired students.     

Experiencing education in the new Christian schools in the United Kingdom: listening to the male graduates

The new independent Christian schools developed by parents and evangelical churches in the United Kingdom since the late 1960s remain controversial among both Christian and secular educators. In response to this controversy, the present study traced 106 men who had graduated from these schools between 1985 and 2003 and analysed their evaluation of the education they had received in these schools within four main themes: the quality of the education, the context of Christian and moral nurture, the quality of relationships (among the pupils, with the teachers and with the wider world) and preparation received for life after leaving school. Although there were some issues of criticism, the balance of opinion among the former pupils within all four areas was generally supportive of the new independent Christian schools, which were generally perceived as having prepared them well for life.     

Burnout and duration of service among Chinese voluntary workers

A survey study conducted among 226 Chinese voluntary workers in Hong Kong showed that satisfaction with voluntary work, integration into the voluntary institution, and burnout syndromes contributed to volunteers' expected duration of service. Regression analyses also showed that different sets of variables predicted different spans of expected duration of service. Work satisfaction was the most salient predictor for expected duration of service from six months to ten years. Lack of personal accomplishment predicted expected duration of service for six to twelve months, whereas emotional exhaustion and depersonalization influenced volunteers' expectation to continue in the service for five to ten years.
