Developmental changes in the effect of inversion: using a picture book to investigate face recognition

A novel child-oriented procedure was used to examine the face-recognition abilities of children as young as 2 years. A recognition task was embedded in a picture book containing a story about two boys and a witch. The story and the task were designed to be entertaining for children of a wide age range. In eight trials, the children were asked to pick out one of the boys from amongst eight distractors as quickly as possible. Response-time data to both upright and inverted conditions were analysed. The results revealed that children aged 6 years onwards showed the classic inversion effect. By contrast, the youngest children, aged 2 to 4 years, were faster at recognising the target face in the inverted condition than in the upright condition. Several possible explanations for this 'inverted inversion effect' are discussed.     

Done in 60 s? Inferring teachers’ subjective well-being from thin slices of nonverbal behavior

Being a teacher is known to be a particularly stressful occupation and as a consequence many teachers suffer from reduced well-being. Thus, it is important to know as soon as possible which individuals are likely to experience reduced well-being in their employment. Therefore, this study investigated whether it is possible to infer teachers’ future well-being from minimal nonverbal information, i.e., thin slices of behavior. Between 2003 and 2006, 50 teachers were filmed while holding a lesson. Naïve observers were shown 60-s clips of these teachers and were asked to predict the teachers’ satisfaction with job, life, and health in 5–8 years. Five to eight years later, the teachers’ satisfaction with job, life, and health was assessed. It was shown that judges highly agree in their predictions. Additionally, these predictions were shown to be accurate for life and job satisfaction. Thus, it is possible to predict a teacher’s well-being on the basis of thin slices of the nonverbal behavior they show while performing their job. These thin slices might therefore allow for a risk assessment in the context of teacher education and such approaches might contribute to teacher professionalism.     

Connaissances et contrôle exécutif : deux facteurs cognitifs de protection contre le vieillissement de la mémoire épisodique ?

In this study we refer to Craik and Bialystok's model distinguishing the “knowledge” (cultural learning experience that forms the basis for knowledge of the world) and the “executive control” (set of operations that control and regulate cognitive performance) as two main factors susceptible accounting for the age-related negative effects on the cognitive functioning, and for a possible age-related protective effect. Thus, the aim of the present study was to examine the possible protective effect of these two factors on the age-related decline in a cued-recall task. Four age groups of participants (20–39 years, 40–59 years, 60–74 years and 75–90 years) were administered with a word-stem cued-recall test to assess episodic memory, a “vocabulary” sub-test of the WAIS-R to assess knowledge and a reading span test to assess control. Results showed an age-related effect on the episodic memory, the control performance and the knowledge measure, indicating that performance decreases with age. A GLM analysis revealed a positive effect of the knowledge and the control factors on the cued-recall performance, and interaction between age and the knowledge factor resulting from a positive effect of the knowledge level only for the youngest group of participants (20–39 years). Furthermore, results revealed an interaction between age and the control factor, indicating a positive effect of the control level for the two oldest groups of participants (60–74 years and 75–90 years). These results suggest that, contrary to the knowledge, the control factor could be an effective protection against the age-related negative effects on the episodic memory.     

A cross-sequential analysis of developmental differences in speed of visual information processing

Development of processing speed was examined in three backward masking studies. The first verified the central nature of backward masking for children aged 8 and 11 years and for adults. The second suggested that task requirements were equivalent for children similar to those in Study 1, and that age differences in performance were not attributable to nonprocessing variables. The main cross-sequential study estimated speed of processing in 80 children (approximately 6 years to 13 years) and young adults using an inspection time task. Target exposure duration was varied to establish the time required to achieve a high level of discriminative accuracy. Estimates of processing speed increased until about 11-13 years of age; beyond this, the trend was less obvious, and it is possible that inspection time asymptotes at around the onset of adolescence. Performance improvement after 1 year could not be explained as resulting from practice since improvement among controls over a period of 2 weeks was significantly less. Correlations between estimates of inspection time made up to 2 years apart found the measure to be reliable.     

Student mental health: A pilot study

In this country, little research has been undertaken into the difficulties faced by students and the contributory stressors. It is apparent that they have a lot with which to content. Identification of stressors, assessement of stress levels and consequences on mental health appear vital.A pilot study was undertaken of 40 studets: 10 males aged under 21 years, ten males 21–40 years, 10 females under the age of 21 and 10 females 21–40 years, The purpose was to identify the potential factors leading to student discontent, problems and stress. Students were in the professions allied to medicine. Oral semi-structured interviews and a written questionnaire were used. Results indicated that for students the major difficulties were coursework and emotional state. Finance was a recurring problem but not as troublesome to the students as the other two problems. What must be considered are ways to alleviate student unhappiness. Emphasis should be placed on prevention where possible. Ongoing counseling throughuot the educational years is desirable as are various programmes which address student concerns. Of particular value would be a Student Mental Health Service. ‘Unnecessary’ coursework could be an added burden.     

Irreversible cerebral function loss (so-called brain death). Further experiences in diagnostic procedures

Analyzing international 15 years experiences the authors characterize the present situation of knowledges and practical possibilities concerning brain death diagnostics. It must be differentiated between generally accepted obliging criterions and the remaining space of responcibility of the neurologist, who is acting as a member of a brain death commission. In this frame procedures have to be chosen, which allow to diagnosticate without any doubt and as early as possible. Further developmental possibilities are shown.     

Phenomenology and the project of naturalization

In recent years, more and more people have started talking about the necessity of reconciling phenomenology with the project of naturalization. Is it possible to bridge the gap between phenomenological analyses and naturalistic models of consciousness? Is it possible to naturalize phenomenology? Given the transcendental philosophically motivated anti-naturalism found in many phenomenologists such a naturalization proposal might seem doomed from the very start, but in this paper I will examine and evaluate some possible alternatives.     

The Withdrawal of Human Projection (Book)

It is possible that religious conversion may be particularly likely at certain times in the life cycle. Many psychological studies on conversion have suggested that adoles- cence, a prime time for conflict, identity crisis, and searching, is the most favorable time for religious conversion. This article presents the results of a research (Kose, 1996) based on interviews with 70 native British converts to Islam that revealed conversions are more likely to occur beyond adolescence. The average conversion age was found to be 29.7 years.     

TRAINING AND COUNSELING OF THE OLDER WORKER1

Mature workers are and will continue to be an important source of labor in the economy. By 1975 approximately one-half of the labor force will be over 45 years of age. Problems of training, re-training, and counseling these workers are examined in this paper in terms of some of their characteristics, such as slower work habits, decreased physical strength, adaptability, and lack of self-confidence. Ways to alleviate or compensate for possible handicaps of older employees through training and counseling programs are suggested.     

Cost–benefit estimates for early intensive behavioral intervention for young children with autism—general model and single state case

Clinical research and public policy reviews that have emerged in the past several years now make it possible to estimate the cost–benefits of early intervention for infants, toddlers, and preschoolers with autism or pervasive development disorder—not otherwise specified (PDD—NOS). Research indicates that with early, intensive intervention based on the principles of applied behavior analysis, substantial numbers of children with autism or PDD—NOS can attain intellectual, academic, communication, social, and daily living skills within the normal range. Representative costs from Pennsylvania, including costs for educational and adult developmental disability services, are applied in a cost–benefit model, assuming average participation in early intensive behavioral intervention (EIBI) for three years between the age of 2 years and school entry. The model applied assumes a range of EIBI effects, with some children ultimately participating in regular education without supports, some in special education, and some in intensive special education. At varying rates of effectiveness and in constant dollars, this model estimates that cost savings range from $187,000 to $203,000 per child for ages 3–22 years, and from $656,000 to $1,082,000 per child for ages 3–55 years. Differences in initial costs of $33,000 and $50,000 per year for EIBI have a modest impact on cost–benefit balance, but are greatly outweighed by estimated savings. The analysis indicates that significant cost-aversion or cost-avoidance may be possible with EIBI. © 1998 John Wiley & Sons, Ltd.     

Estimating retest effects in longitudinal assessments of cognitive functioning in adults between 18 and 60 years of age

Several analyses were conducted on data from samples of adults between 18 and 58 years of age who completed the same cognitive tests after an interval ranging from less than 1 week to 35 years. Because the retest interval varied across individuals, it was possible to determine the length of time needed before the gains associated with a retest decreased to 0 and to obtain simultaneous estimates of the magnitude of effects associated with increased age and a prior assessment. The results indicated that for adults within this age range, 7 or more years were needed before positive retest effects were no longer detectable. Age effects in longitudinal comparisons could be interpreted in terms of large positive effects associated with a prior assessment and negative effects associated with age that were comparable in magnitude to those observed in cross-sectional comparisons.     

A comparison of adult women's and men's ascriptions of negative traits to the same and opposite sex

College students (N=135), ranging from 19 to 55 years of age, were studied to determine their sex stereotypes. Results from the present study indicated that adult males were significantly more negative than adult females in their evaluations of both sexes. One possible explanation that may be offered to account for these findings is that current emphasis of female rights may be causing negativistic reactions on the part of males toward both sex groups.     

Das Ausmaß von Müdigkeit und Erschöpfbarkeit in der über 60-jährigen Normalbevölkerung in Deutschland

In a community-based random sample of 622 elderly persons over 60 years of age, fatigue was assessed by means of the multidimensional fatigue inventory (MFI; a self-assessment measure). Higher fatigue values were found with increasing age, particularly physical feelings of fatigue, reduced activity and reduced motivation. Fatigue was associated with depression, with a low health-related quality of life and with subjective physical complaints. Distinct fatigue symptoms in the elderly should therefore be regarded as possible indicators for somatic and/or psychological burdens and should receive diagnostic and therapeutic attention. In the present paper, mean values and percentiles for different age groups over 60 years are given as norm values for the normal population over 60 years of age.     

The cognitive foundations of reading and arithmetic skills in 7- to 10-year-olds

A range of possible predictors of arithmetic and reading were assessed in a large sample (N=162) of children between ages 7 years 5 months and 10 years 4 months. A confirmatory factor analysis of the predictors revealed a good fit to a model consisting of four latent variables (verbal ability, nonverbal ability, search speed, and phonological memory) and two manifest variables (digit comparison and phoneme deletion). A path analysis showed that digit comparison and verbal ability were unique predictors of variations in arithmetic skills, whereas phoneme deletion and verbal ability were unique predictors of variations in reading skills. These results confirm earlier findings that phoneme deletion ability appears to be a critical foundation for learning to read (decode). In addition, variations in the speed of accessing numerical quantity information appear to be a critical foundation for the development of arithmetic skills.     

Quantifying over the reals

Peter Geach proposed a substitutional construal of quantification over thirty years ago. It is not standardly substitutional since it is not tied to those substitution instances currently available to us; rather, it is pegged to possible substitution instances. We argue that (i) quantification over the real numbers can be construed substitutionally following Geach's idea; (ii) a price to be paid, if it is that, is intuitionism; (iii) quantification, thus conceived, does not in itself relieve us of ontological commitment to real numbers.     

MOTHERS' ALCOHOL CONSUMPTION DURING PREGNANCY:

Abstract— Fourteen-year-old adolescents' behavior on a spatial-visual reasoning task was associated with self-report of their mothers' alcohol consumption during pregnancy, IS years earlier The task was arranged so that it was possible to evaluate the examinees' tendency to respond rapidly and less accurately, or slowly and more accurately The greater the mother's reported drinking, the faster and less accurately the adolescent responded The decrement in visual-spatial reasoning related to alcohol appears to be linked to a tendency toward impulsive responding

Differences in protective factors of substance use in early and middle adolescence

This study focuses on possible differences in protective factors of substance use in early and middle adolescence. These possible differences are analysed by means of the same structural equation model applied to two different samples of adolescents: the first sample is made up of 450 adolescents, ages 12 to 14 years, and second of 203 adolescents, ages 15 to 17 years. The results indicate that adequate family communication is a protective factor in both samples, whereas high social self-esteem is proposed as a risk factor in middle adolescence. The adolescent's family self-esteem and attitudes towards authority are also relevant factors in both samples. These results may have important implications in the development of future intervention programmes.     

Recent decreasing trend in U.S. juvenile delinquency attributable to changes in maternal age

Two documented associations, viz., a negative one between maternal age and externalizing behavior of the offspring and a positive one between externalizing behavior in childhood and the probability of later (juvenile) delinquency, lead to the prediction that cohort-changes in crime rate over the years are associated with the age of the mothers of these cohorts when the children were born. This prediction was tested by comparing U.S. crime figures between 1987 and 1997 with maternal age figures 17 years earlier (1970-1980). Both time series show a close resemblance. Although causality from two different time series cannot be asserted, the existence of such a relationship is made plausible. Two different hypotheses are presented about the possible nature of causality. Results may be of value for studies in crime epidemiology.
