Qualitative data are used to examine parents’ support to their adult children, and their motivations and feelings about it.
The sample is 40 adult children and parents from four racial/ethnic groups: African-Americans, Asian-Americans, non-Latino
Whites, and Latinos. Ideals of adult independence versus interdependence emerge as determinants of feelings about aiding adult
children. The ambivalence concept provides the means to elucidate the tensions between these ideologies and children’s structurally
shaped circumstances. Parental assistance to adult children was seen as acceptable for education, home ownership, and on behalf
of young children, especially if the child was “working hard.” Parents still provided aid, however, even if these conditions
were not met. In these situations, more intrafamilial tension characterized the aid transfer. 相似文献
Quantity discrimination is adaptive in a variety of ecological contexts and different taxa discriminate stimuli differing
in numerousness, both in the wild and in laboratory settings. Quantity discrimination between object arrays has been suggested
to be more demanding than between food arrays but, to our knowledge, the same paradigm has never been used to directly compare
them. We investigated to what extent capuchin monkeys’ relative numerousness judgments (RNJs) with food and token are alike.
Tokens are inherently non-valuable objects that acquire an associative value upon exchange with the experimenter. Our aims
were (1) to assess capuchins’ RNJs with food (Experiment 1) and with tokens (Experiment 2) by presenting all the possible
pair-wise choices between one to five items, and (2) to evaluate on which of the two proposed non-verbal mechanisms underlying
quantity discrimination (analogue magnitude and object file system) capuchins relied upon. In both conditions capuchins reliably
selected the larger amount of items, although their performance was higher with food than with tokens. The influence of the
ratio between arrays on performance indicates that capuchins relied on the same system for numerical representation, namely
analogue magnitude, regardless of the type of stimuli (food or tokens) and across both the small and large number ranges. 相似文献
We propose and test two alternative hypotheses bearing on the dual roles of group variability and typicality when people form impressions of single category members. The latitude of acceptance hypothesis suggests that a wider range of individual group members are likely to be seen as good-fitting members (i.e., typical) if the group is heterogeneous, thereby increasing the extent to which stereotypical attitudes are used as a basis for responding to these persons. In contrast, the typicality-functionality hypothesis suggests that typicality plays different roles depending on group variability. This view suggests that typicality plays the “gatekeeper function” as postulated by Fiske and Neuberg (1990) when the group is homogeneous, but not when it is heterogeneous. Across two studies, stronger support was found for the typicality-functionality hypothesis. Implications for the extant literature on category-based processing are discussed. 相似文献
Young maltreated children, birth to three years, represent the age group with the highest rates of maltreatment in the United
States (ACYF 2007). There are few studies to date that have investigated early childhood maltreatment and its effects on emotion
regulatory processes and psychopathology. In response, the current investigation uses a dyadic assessment procedure to examine
the relationship between parenting, emotion regulation, and symptoms of psychopathology among maltreating and non-maltreating
parent–child interactions. The participants in this study were 123 children (66 maltreated and 57 nonmaltreated) from ages
1–3. Child and parent affect and child effortful control were observed during a parent–child interaction task. Symptoms of
psychopathology were measured using the Child Behavior Checklist. The maltreated children exhibited more anger, more internalizing
symptomatology, and less positive affect compared to non-maltreated children. Among maltreated children, emotion dysregulation
was associated with internalizing symptomatology. Moreover, these data reveal parental positive affect was associated with
lower child internalizing symptomatology and parental anger was associated with higher child internalizing symptomatology
in the entire sample. This investigation offers evidence that emotion dysregulation subsequent to poor dyadic interactions
is associated with early child maltreatment. These data suggest that maltreated children experience difficulties in emotion
regulation which may be related to their higher levels of behavioral symptomatology. 相似文献
Five word-spotting experiments explored the role of consonantal and vocalic phonotactic cues in the segmentation of spoken Italian. The first set of experiments tested listeners' sensitivity to phonotactic constraints cueing syllable boundaries. Participants were slower in spotting words in nonsense strings when target onsets were misaligned (e.g., lago in ri.blago) than when they were aligned (e.g., lago in rin.lago) with phonotactically determined syllabic boundaries. This effect held also for sequences that occur only word-medially (e.g., /tl/ in ri.tlago), and competition effects could not account for the disadvantage in the misaligned condition. Similarly, target detections were slower when their offsets were misaligned (e.g., cittá in cittáu.ba) than when they were aligned (e.g., cittá in cittá.oba) with a phonotactic syllabic boundary. The second set of experiments tested listeners' sensitivity to phonotactic cues, which specifically signal lexical (and not just syllable) boundaries. Results corroborate the role of syllabic information in speech segmentation and suggest that Italian listeners make little use of additional phonotactic information that specifically cues word boundaries. 相似文献
Three experiments were performed in an attempt to achieve a better understanding of the effect of dopamine on handwriting. In the first experiment, kinematic aspects of handwriting movements were compared between healthy participants and patients with Parkinson's disease (PD) on their usual dopaminergic treatment and following withdrawal of dopaminergic medication. In the second experiment, the writing performance of healthy participants with a hyperechogenicity of the substantia nigra as detected by transcranial sonography (TCS) was compared with the performance of healthy participants with low echogenicity of the substantia nigra. The third experiment examined the effect of central dopamine reduction on kinematic aspects of handwriting movements in healthy adults using acute phenylalanine and tyrosine depletion (APTD). A digitising tablet was used for the assessment of handwriting movements. Participants were asked to perform a simple writing task. Movement time, distance, velocity, acceleration and measures of fluency of handwriting movements were measured. The kinematic analysis of handwriting movements revealed that alterations of central dopaminergic neurotransmission adversely affect movement execution during handwriting. In comparison to the automatic processing of handwriting movements displayed by control participants, participants with an altered dopaminergic neurotransmission shifted from an automatic to a controlled processing of movement execution. Central dopamine appears to be of particular importance with regard to the automatic execution of well-learned movements. 相似文献
Many animals use spatial memory. Although much work has examined the accuracy of spatial memory, few studies have explicitly
focused on its longevity. The importance of long-term spatial memory for foraging has been demonstrated in several cases.
However, the importance of such long-term memory for all animals is unclear. In this study, we present the first evidence
that a parid species (the black-capped chickadee, Poecile atricapillus) can remember the location of a single food item for at least 6 months under an associative-learning spatial memory paradigm
with multiple reinforcements. We did not detect a significant difference in memory longevity between two populations of chickadees
shown previously to differ in short-term spatial memory and hippocampal morphology, an area of the brain involved in spatial
memory. Our study showed that small birds such as parids can maintain spatial memories for long periods, a feat shown previously
only in corvids. Moreover, we were able to demonstrate this longevity within the context of only 16 repeated trials. We speculate
that this ability may potentially be useful in relocating caches if reinforced by repeated visits. Future studies are necessary
to test whether our results were specifically due to multiple reinforcements of the food-containing location and whether parids
may have similar memory longevity during food-caching experiences in the wild. 相似文献
A contentious debate between the modern and postmodern epistemologies continue to wage on since the rise of constructivism and social constructionism in the 1990s. This debate has led to both modern and postmodernists falling into an either/or mindset. Others have proposed a solution, the both-and approach, that emphasizes integration of different therapeutic camps. Intentionality is a core component of this approach, as therapists must understand how employed interventions flow from the epistemology and theoretical orientation under which they operate. Another core component of this approach is tailoring the integration to the specific context of the client case. With this understanding and tailoring, therapists can utilize methods across the modern/postmodern divide, as they will coherently flow from their original epistemology and theoretical orientation. Applying methods from both modernism and postmodernism, then, enhances therapists’ therapeutic repertoire, allowing for more opportunities to adapt treatment to each client case. Altogether, the quality of services improve and the amount of clients therapists can help increases as well. This paper will provide an application of the both-and approach to a case study to provide an example of how the said method can be employed in therapy.
