Processing within the dorsal visual stream subserves object-directed action, whereas visual object recognition is mediated by the ventral visual stream. Recent findings suggest that the computations performed by the dorsal stream can nevertheless influence object recognition. Little is known, however, about the type of dorsal stream information that is available to assist in object recognition. Here, we present a series of experiments that explored different psychophysical manipulations known to bias the processing of a stimulus toward the dorsal visual stream in order to isolate its contribution to object recognition. We show that elongated-shaped stimuli, regardless of their semantic category and familiarity, when processed by the dorsal stream, elicit visuomotor grasp-related information that affects how we categorize manipulable objects. Elongated stimuli may reduce ambiguity during grasp preparation by providing a coarse cue to hand shaping and orientation that is sufficient to support action planning. We propose that this dorsal-stream-based analysis of elongation along a principal axis is the basis for how the dorsal visual object processing stream can affect categorization of manipulable objects. 相似文献

The particular challenges posed by pediatric asthma may have a negative impact on the adaptation of children and their parents. From a transactional approach it is important to examine how reciprocal links between children and parents contribute to explain their adaptation and under which conditions these associations occur. This cross-sectional study aimed at examining the direct and indirect links between children’s and parents’ perceptions of family relationships and adaptation, separately (within-subjects) and across participants (cross-lagged effects), and the role of asthma severity in moderating these associations. The sample comprised 257 children with asthma, aged between 8 and 18 years-old, and one of their parents. Both family members completed self-reported questionnaires on family relationships (cohesion and expressiveness) and adaptation indicators (quality of life and psychological functioning). Physicians assessed asthma severity. Structural Equation Modeling was used to test within-subjects and cross-lagged paths between children’s and parents’ family relationships and adaptation. The model explained 47 % of children’s and 30 % of parents’ adaptation: family relationships were positively associated with adaptation, directly for children and parents, and indirectly across family members. Asthma severity moderated the association between family relationships and health-related quality of life for children: stronger associations were observed in the presence of persistent asthma. These results highlight the need of including psychological interventions in pediatric healthcare focused on family relationships as potential targets for improving children’s and parents’ quality of life and psychological functioning, and identified the children with persistent asthma as a group that would most benefit from family-based interventions. 相似文献

Unlike most people, those who are characterized by a repressive coping style report high levels of physical (sensory) pain but low levels of emotional distress (affective pain), which is a discrepancy that may suggest a "conversion" process. In two studies, we tested an attention allocation model, proposing that repressors direct attention away from threatening negative affective information and toward nonthreatening physical pain information during emotionally arousing (painful) situations. In Study 1, 84 participants underwent a cold pressor and then recovered. Repressors reported greater pain during recovery than low- and high-anxious participants, but they reported lower distress than high-anxious participants. Repressors reported significant and large discrepancies between high pain and low distress, whereas these differences were less pronounced for other groups. In Study 2, 77 participants underwent an ischemic pain task while performing a modified dot-probe task with sensory and negative affective pain words as stimuli. Repressors showed increasing biases away from affective pain words and toward sensory pain words as the pain task continued, whereas low- and high-anxious participants did not show these shifts in attention. The results support the notion that conversion among repressors may involve a process by which attention is directed away from emotional distress during noxious stimulation and is focused instead on sensory information from pain. 相似文献

There is contention concerning the role that domestication plays in the responsiveness of canids to human social cues, with most studies investigating abilities of recognized domestic dog breeds or wolves. Valuable insight regarding the evolution of social communication with humans might be gained by investigating Australian dingoes, which have an early history of domestication, but have been free-ranging in Australia for approximately 3500–5000 years. Seven ‘pure’ dingoes were tested outdoors by a familiar experimenter using the object-choice paradigm to determine whether they could follow nine human communicative gestures previously tested with domestic dogs and captive wolves. Dingoes passed all cues significantly above control, including the “benchmark” momentary distal pointing, with the exception of gaze only, gaze and point, and pointing from the incorrect location. Dingo performance appears to lie somewhere between wolves and dogs, which suggests that domestication may have played a role in their ability to comprehend human gestures. 相似文献

Training individuals who are at risk of unemployment/underemployment to increase their employability is a mission of many nonprofit agencies. These training programs, often supported by government funding, attempt to reduce these individuals’ reliance on government assistance. The purpose of this study is to obtain hard data and an in‐depth understanding about the factors that contribute to the success of the Green Construction training program. The methodology used is a multimethod, multimeasure approach, which provides a reasonably robust triangulation of results. The findings indicate that the program is successful because it has good participant retention, knowledge gain, and placement rates. 相似文献

Objective: This study explores the perspectives of both patients and family members regarding the impact of chronic obstructive pulmonary disease (COPD) in their family life.Design: An exploratory qualitative study was conducted with patients and their family members in the chronic phase of COPD. Individual interviews were performed to explore participants’ perspectives and submitted to thematic analysis.Results: Six major themes emerged from patients’ perspective: (1) impact of COPD symptoms on personal and family daily life; (2) (over)protective family support; (3) difficulties in couple communication; (4) sense of identity loss; (5) fear of COPD progression; and (6) coping resources. Five main themes emerged from the family members’ perspective: (1) restrictions in family’s social life; (2) emotional distress related to COPD exacerbations; (3) tension in couple relationship; (4) financial strain of COPD; and (5) coping resources.Conclusions: The overall findings illustrate the complex interaction between the experience of living with COPD and communication patterns, emotional states, social support and social roles within the family. The results highlight the need to develop family-based interventions to facilitate a functional adjustment to COPD. However, these interventions in COPD remain undeveloped and empirical evidence is needed. 相似文献

AbstractObjective: This qualitative study sought to identify and describe patients’ variant perceptions of disease severity after receiving a type 2 diabetes (T2DM) or prediabetes (preDM) diagnosis.Design: Researchers interviewed 29 patients from two US medical centers to ascertain perceptions of severity. We used the constant comparative method from a grounded theory approach to identify themes from patients’ perspectives that inform their disease severity. This approach was used to help translate research to practice and ultimately identify intervention strategies informed by authentic experiences of preDM and T2DM patients.Results: Perceptions of disease severity fell into two groups: high and low severity. Patients diagnosed with T2DM and preDM emerged in both groups and were comparative in terms of sample size, gender, and ethnic diversity. Several factors contributed to patients’ beliefs, including what they were told about the disease, observations from experiences within their own social network, and information from formal diabetes classes and their own research. The two perspectives diverged when patients described how their belief was informed by three thematic properties or personal factors: (i) fears; (ii) clinician communication; and (iii) social comparisons.Conclusions: Beliefs about severity are influenced by patients’ fears, interactions with clinicians, and experiences within their social networks. These findings show that when interacting with patients with T2DM or preDM, clinicians should elicit patient perceptions of disease severity so they may then tailor the discussion to address these perceptions and help patients grasp the severity of these conditions. 相似文献

A qualitative psychoanalytic clinical research project using a post-Kleinian contemporary approach was undertaken by a team of seven qualified and experienced child psychotherapists working in community Tier 3 Child and Adolescent Mental Health Services (CAMHS). A number of referred young people who deliberately harmed themselves or attempted suicide, who fulfilled the inclusion criteria and consented to participate, were offered an extended individual and family assessment. Grounded Theory analysis of the qualitative data led to the formulation of the Truth Danger Theory. Typical situations in which suicidal behaviour occurred were identified, including intergenerational confusion, neglect, physical and/or sexual abuse within the family, Oedipal conflict, maternal depression and families in which there was a chronically ill sibling. We found that there was a marked disparity between the young person's experience of relationships in the family and the family's own account of their situation, a fractured reality. This can be reflected in an incongruence in the young person's presentation, which may be misleading when assessing risk. The young person feels him/herself to be in a dead end from which there seems to be no escape. Self-harm, for some, contains this impossible dilemma (albeit pathologically) but when it does not, suicide may seem the only option. The Truth Danger Theory provides explanations and predictions for suicidal behaviour and has implications for clinical practice. 相似文献

A defining characteristic of psychopathy is the willingness to intentionally commit moral transgressions against others without guilt or remorse. Despite this "moral insensitivity," the behavioral and neural correlates of moral decision-making in psychopathy have not been well studied. To address this issue, the authors used functional magnetic resonance imaging (fMRI) to record hemodynamic activity in 72 incarcerated male adults, stratified into psychopathic (n = 16) and nonpsychopathic (n = 16) groups based on scores from the Hare Psychopathy Checklist-Revised (R. D. Hare, 2003), while they made decisions regarding the severity of moral violations of pictures that did or did not depict moral situations. Consistent with hypotheses, an analysis of brain activity during the evaluation of pictures depicting moral violations in psychopaths versus nonpsychopaths showed atypical activity in several regions involved in moral decision-making. This included reduced moral/nonmoral picture distinctions in the ventromedial prefrontal cortex and anterior temporal cortex in psychopaths relative to nonpsychopaths. In a separate analysis, the association between severity of moral violation ratings and brain activity across participants was compared in psychopaths versus nonpsychopaths. Results revealed a positive association between amygdala activity and severity ratings that was greater in nonpsychopaths than psychopaths, and a negative association between posterior temporal activity and severity ratings that was greater in psychopaths than nonpsychopaths. These results reveal potential neural underpinnings of moral insensitivity in psychopathy and are discussed with reference to neurobiological models of morality and psychopathy. 相似文献

This paper provides an argument for a more socially relevant philosophy of science (SRPOS). Our aims in this paper are to
characterize this body of work in philosophy of science, to argue for its importance, and to demonstrate that there are significant
opportunities for philosophy of science to engage with and support this type of research. The impetus of this project was
a keen sense of missed opportunities for philosophy of science to have a broader social impact. We illustrate various ways
in which SRPOS can provide social benefits, as well as benefits to scientific practice and philosophy itself. Also, SRPOS
is consistent with some historical and contemporary goals of philosophy of science. We’re calling for an expansion of philosophy
of science to include more of this type of work. In order to support this expansion, we characterize philosophy of science
as an epistemic community and examine the culture and practices of philosophy of science that can help or hinder research
in this area. 相似文献
