The Structure of Frege's Thoughts

Fregean thoughts (i.e. the senses of assertoric sentences) are structured entities because they are composed of simpler senses that are somehow ordered and interconnected. The constituent senses form a unity because some of them are ‘saturated’ and some ‘unsaturated’. This paper shows that Frege's explanation of the structure of thoughts, which is based on the ‘saturated/unsaturated’ distinction, is by no means sufficient because it permits what I call ‘wild analyses’, which have certain unwelcome consequences. Wild analyses are made possible because any ‘unsaturated’ sense that is a mode of presentation of a concept together with any ‘saturated’ sense forms a thought. The reason is that any concept can be applied to any object (which is presented by a ‘saturated’ sense). This stems from the fact that Frege was willing to admit only total functions. It is also briefly suggested what should be done to block wild analyses.     

Robust patterns and individual variations: Stability and predictors of infant behavior in the still-face paradigm

In the present study we examined key issues regarding infant behavior in the still-face paradigm (SFP) in terms of individual variations, stability, and predictors. The sample consisted of 115 mothers and infants, with assessments at ages 3 and 6 months, including observations of maternal and infant behavior in the SFP, and parent reports of infant temperament. Both robust patterns and individual variations in infant SFP behaviors were found, with only a minority of infants showing the expected patterns for negative affect and gaze. Infant behavior patterns showed no stability from age 3 to 6 months, and infant gaze was related to more pronounced behavior changes across the SFP. Maternal sensitivity in the SFP baseline was related to some aspects of infant SFP behavior. Consistent with the differential susceptibility hypothesis, in infants with a more difficult temperament maternal sensitivity predicted a more pronounced expected pattern of changes in infant positive affect across the SFP, whereas this was not the case for infants with a more easy temperament.     

A Pilot Randomized Controlled Trial of the Effects of Cognitive-Behavioral Therapy for Insomnia on Sleep and Daytime Functioning in College Students

The purpose of this study was to pilot test if cognitive behavioral therapy for insomnia (CBT-I) is an effective intervention for insomnia and daytime functioning in college students. College students’ developmental stage and lifestyle are significantly different than the general adult population, yet there have been no studies of CBT-I in this age group.     

Type a behavior pattern in mothers of infants: An exploration of associations with attachment,sensitive caregiving,and life-events

Abstract

In the present study. 83 lower- to upper-middle class mothers of first-born, 12-month-old infants were interviewed with the Adult Attachment Interview (George, Kaplan, and Main, 1985), and completed the Groninger Intelligence Test (Luteijn and Van der Ploeg, 1982). Eighteen months after the beginning of the study, 67 mothers (81% of the original sample) were interviewed with the Structured Interview (Rosenman, 1978), and were observed during a brief, semi-structured play session at home with their child - at that time a 2.5-years-old toddler. They also completed a checklist about major life-events that had occurred during the past 18 months. A large majority of these mothers of young children (81%) showed Type A behavior patterns. The job of parenting, indeed, appears to be stressful. Attachment and Type A behaviors, however, did not seem to be related, probably because the influence of attachment is restricted to the regulation of emotions in intimate relationships. Yet, Type A behavior predicted a more sensitive parenting style than Type B did. All mothers who experienced negative life-events or Serious health problems in the recent past showed Type A behavior patterns. Our findings show that the Structured Interview can be applied in a valid manner to mothers of young children passing trough a demanding phase in their lives. Further research is needed to uncover the causes of the high prevalence of Type A behaviors in young mothers.     

Father‐Involvement in a Refugee Sample: Relations between Posttraumatic Stress and Caregiving

Despite increased attention to the role of fathers within families, there is still a dearth of studies on the impact of trauma on father‐involvement. This study investigates the quantity of father‐involvement and the influence of posttraumatic stress on the quality of involvement in a refugee and asylum seeker population. Eighty refugees and asylum seekers and their young children (aged 18–42 months) were recruited. Measures included assessment of parental trauma (Harvard Trauma Questionnaire), quantity and quality of involvement (quantity of caregiving and Emotional Availability Scales), and perception of the father–child relationship (interview). The results show that fathers were less involved in caregiving tasks and play activities than mothers. No parental gender differences were found on each of the Emotional Availability Scales. Traumatic stress symptoms negatively affected the perception and the actual quality of parent–child interaction (sensitivity, structuring, nonhostility). Nevertheless, almost all fathers described their relationship with their child as good and their child as very important to them. As the quality of father‐involvement is of importance to the development of the child, traumatized fathers are as much in need of clinical intervention as mothers. Despite the impact of posttraumatic stress, refugee fathers clearly are involved in the lives of their children. Mechanisms such as a deliberate withdrawal when stressed and compensation might enable affected fathers to step into the interaction when needed, raise the quality of involvement with their child, and diminish the negative impact of stress resulting from trauma and migration.     

Gender Stereotypes in the Family Context: Mothers, Fathers, and Siblings

Gender stereotypes of children and their parents were examined. Participants included 355 three-year-old children, their one-year-old siblings, and their mothers and fathers. Families were selected from the Western region of the Netherlands. Implicit gender stereotypes were assessed with computerized versions of the Action Inference Paradigm (AIP; both child and parents) and the Implicit Association Test (parent only). Parental explicit gender stereotypes were measured with the Child Rearing Sex-Role Attitude Scale. Findings revealed that mothers had stronger implicit gender stereotypes than fathers, whereas fathers had stronger explicit stereotypes than mothers. Fathers with same-gender children had stronger implicit gender stereotypes about adults than parents with mixed-gender children. For the children, girls’ implicit gender stereotypes were significantly predicted by their mother’s implicit gender stereotypes about children. This association could only be observed when the AIP was used to assess the stereotypes of both parent and child. A family systems model is applicable to the study of gender stereotypes.     

Interactions between mothers and children: impacts of maternal and child anxiety

This study, an expansion of an earlier study of parenting behaviors of anxious mothers, examined the relationship of both mother and child anxiety disorders to mother behavior in parent--child interactions. Participants were 68 mother--child dyads with children ranging in age from 7 to 15 years. Mothers and children completed diagnostic evaluations and engaged in conversational tasks; behaviors were rated by coders who were blind to diagnosis. Mothers of anxious children, regardless of their own anxiety, were less warm (p <.05) toward their children. They also granted less autonomy (p <.01). There was an interaction between mother and child anxiety in predicting maternal catastrophizing (p <.01), with anxious mothers and nonanxious mothers of anxious children likely to catastrophize. Theoretical and research implications are discussed.     

IQ on the rise: the Flynn effect in rural Kenyan children

Abstract - Multiple studies have documented significant IQ gains over time, a phenomenon labeled the Flynn effect. Data from 20 industrialized nations show massive IQ gains over time, most notably in culturally reduced tests like the Raven's Progressive Matrices. To our knowledge, however, this is the first study to document the Flynn effect in a rural area of a developing country. Data for this project were collected during two large studies in Embu, Kenya, in 1984 and 1998. Results strongly support a Flynn effect over this 14-year period, with the most significant gains found in Raven's matrices. Previously hypothesized explanations (e.g., improved nutrition; increased environmental complexity; and family, parental, school, and methodological factors) for the Flynn effect are evaluated for their relevance in this community, and other potential factors are reviewed. The hypotheses that resonate best with our findings are those related to parents' literacy, family structure, and children's nutrition and health.     

Use of a task-oriented self-instruction method to support children in primary school with poor handwriting quality and speed

Two studies were conducted to investigate the effect of a task-specific self-instruction intervention to improve handwriting ability of children with poor handwriting quality in schools for regular education (Study 1) and children with poor handwriting quality in schools for special education (Study 2). Study 1 showed that children with poor handwriting quality who received handwriting intervention on an individual basis for three months improved on average more on quality of writing than control children without handwriting problems who did not receive intervention. In contrast, the control group improved more in speed of writing after the intervention period. At an individual level, three out of the seven children with poor handwriting quality before intervention were not classified as such anymore after the intervention period. Study 2 showed that after six months of intervention in a group setting children with poor handwriting quality improved their quality of writing more so than children with poor handwriting quality who had not received intervention. On speed of handwriting no significant group differences emerged. We conclude that the task-oriented self-instruction method applied in this study seems to improve especially the quality of handwriting, not speed, of children initially identified as having poor handwriting quality.
