Infants Discriminate the Affective Expressions of their Peers: The Roles of Age and Familiarization Time

Research examining infants’ discrimination of affect often uses unfamiliar faces and voices of adults. Recently, research has examined infant discrimination of affect in familiar faces and voices. In much of this research, infants were habituated to the affective expressions using a “standard” 50% habituation criterion. We extend this line of research by examining infants’ discrimination of unfamiliar peers’, that is, 4‐month‐olds, dynamic, facial, and vocal affective expressions and assessing how discrimination is affected by changing the habituation criterion. In two experiments, using an infant‐controlled habituation design, we explored 3‐ and 5‐month‐olds’ discrimination of their peers’ dynamic audiovisual displays of positive and negative expressions of affect. Results of Experiment 1, using a 50% habituation criterion, revealed that 5‐month‐olds, but not 3‐month‐olds discriminated the affective expressions of their peers. In Experiment 2, we examined whether 3‐month‐olds’ lack of discrimination in Experiment 1 was a result of insufficient habituation (i.e., familiarization). Specifically, 3‐month‐olds were habituated using a 70% habituation criterion, providing them with longer familiarization time. Results revealed that using the more stringent habituation criterion, 3‐month‐olds showed longer habituation times, that is increased familiarization, and discriminated their peers’ affective expressions. Results are discussed in terms of infants’ discrimination of affect, the role of familiarization time, and limitations of the 50% habituation criterion.     

Multicultural nationalism? National identities among minority groups in Scotland’s census

This paper uses data from a new question in the 2011 UK censuses of population to investigate national identities among ethnic and religious minorities. It focuses primarily on Scotland, while presenting comparative data for England and Wales. A robust comparison of national identities between different minorities in Scotland and with similar groups in other nations of Britain has previously not been possible because ethnic and religious minority groups represent a small proportion of Scotland’s population and are weakly represented in sample surveys. The new census question on national identity therefore offers an unprecedented opportunity for this kind of analysis. The analysis is used to critically evaluate previous claims of the existence of multicultural nationalism in Scotland and previous research that has suggested that Scottish identity is relatively inclusive of people in minority groups. The findings suggest that while Scottish national identity is relatively inclusive of minorities in some respects, the conclusions of previous research should be treated with some caution.     

Microanalysis of 4-Month Infant Vocal Affect Qualities and Maternal Postpartum Depression

This study examined the association of 6-week maternal self-report depressive symptoms measured by the Center for Epidemiological Studies-Depression Scale (CES-D) with 4-month infant vocal affect qualities. This was part a larger study which examined many additional domains of both infant and maternal behavior. Infant vocal affect qualities were examined in 122 4-month old infants during face-to-face play in relation to 6-week maternal depressive symptoms. Mothers were categorized depressed (26.2%) based on a 16+ cutoff on the CES-D. Videotaped interactions were coded on a 1-s time basis for infant vocal affect qualities (high positive, neutral/positive, fuss/whimper, cry, angry protest and silent.) Infants of depressed mothers were more vocally activated in both positive and negative qualities. In addition, infants of depressed mothers were more vocally variable, specifically in and out of fuss/whimper, as well as more likely to change, rather than maintain vocal states.     

Correlates of physical activity participation in community-dwelling older adults

The authors examined factors related to participation in walking, gardening or yard work, and sports or exercise in 686 community-dwelling adults 60-95 years of age from Wave IV of the population-based Americans' Changing Lives Study. Logistic regression revealed that male gender, being married, and better functional health were associated with greater likelihood of participating in gardening or yard work (p < .05). Male gender, better functional health, and lower body-mass index were independently associated with greater likelihood of walking (p < .05). Increasing age, male gender, higher education, and better functional health were associated with greater likelihood of participating in sports or exercise (p < .05). Subsequent analyses yielded an interaction of functional health by gender in sport or exercise participation (p = .06), suggesting a greater association between functional health and participation in men. Gender and functional health appear to be particularly important for physical activity participation, which may be useful in guiding future research. Attention to different subgroups may be needed to promote participation in specific activities.     

Donald R. Cressey: An Intellectual Portrait of a Criminologist

The late Donald R. Cressey (1919–1987) was a central figure in twentieth century American criminology. A distinctive feature of criminology since the 1930s has been the dominance of sociology among the various disciplines studying crime and criminal justice. Cressey's contributions to the sociology of crime and delinquency came from his teaching, scholarship, and involvement in criminal justice policy. He was best known for his carrying on the tradition of Edwin Sutherland in taking Sutherland's criminology textbook through many revised editions after Sutherland's passing and for his pioneering, innovative contributions to the study of organized crime, prisons, and criminological theory. He also made central and lasting contributions to the sociology of criminal law and white collar crime. His ideas in each of these areas are reviewed to produce a portrait or profile of what he added to criminology, to remind those who know it already and to introduce it to those who may not.     

Psychiatric diagnosis as reified measurement

Throughout the 1980s, psychiatry has promoted diagnosis--with its language of categories--as the preeminent measure of psychological problems. In clinical psychiatry, the decade opened with the publication of the Diagnostic and Statistical Manual of Mental Disorders-III (DSM-III). In psychiatric epidemiology, the decade saw the development of the Diagnostic Interview Schedule (DIS) and its use in the large-scale Epidemiologic Catchment Area (ECA) surveys. Proponents of the diagnostic approach herald the DIS as a breakthrough. We argue, on the contrary, that diagnosis as a form of measurement hinders understanding. If the ECA studies provide new insight into the patterns and causes of psychological problems, they will do so despite the use of diagnostic measurement. We present here a critical analysis of the inherent weaknesses of diagnosis as a form of measurement, particularly as a means of representing psychological problems. First, we describe the weaknesses: diagnosis treats attributes as entities; it reduces the signal but not the noise; and it collapses the structural relationships. Second, we offer an interpretation of why psychiatry promotes a form of measurement poorly suited to its subject: the linguistic legacy of nineteenth-century biology and epidemiology; the social construction of the need for mental health services; and the enclosure of a scientific and professional domain. Third, we conclude that diagnostic measurement impedes understanding. We recommend eliminating diagnosis from research on the nature, causes, and consequences of mental, emotional, and behavioral problems.

Characteristics of men and women who complete or exit from an on-line internet sexuality questionnaire: a study of instrument dropout biases

This study compared respondents who completed an Internet sexuality questionnaire and those who dropped out before completion. The study was in Swedish and comprised 3,614 respondents over a 2-week period (53% males, 47% females). There were significant differences between males, of whom 51% dropped out before completion of the 175-item questionnaire, and females, of whom 43% dropped out. Dropout in both genders followed a curve of negative acceleration. The data suggest that dropout is likely to be significant and gender and demographically biased, and to occur significantly earlier for men than for women. Geography, education, sexual orientation, age, relationship status, living arrangements, and Internet connection speed were related to dropout for men, while only relationship status and living arrangements, which were in the opposite direction from men, were related to dropout in women.
