We examined lay perceptions of what counts as a decision. Eighty-six subjects read 10 scenarios that described clear decisions (e.g., choosing a graduate school), clear “nondecisions” (e.g., an accidental wrong turn), or ambiguous actions (e.g., eating a donut when on a diet or allowing someone else to make the decision). The subjects rated each scenario as to whether the actor had made a decision and also rated six other attributes. The scenarios were rated as clearly illustrating a decision if the actor engaged in a lot of thought and did not act reflexively. Consideration of consequences and having alternatives were moderately related to decision ratings, whereas having self-control problems and the influence of physiological drives showed little relationship with decision ratings. Thus, lay concepts of decision making differ from decision theory in that thoughtful, intentional behavior is more important in defining a decision than are decision theoretic components, such as alternatives and consequences. 相似文献

Research is equivocal concerning the relationship between parental psychological distress and infant cognitive functioning. Four potential limitations of the literature are addressed: reliance on mothers' but not fathers' psychological distress, use of categorical measures of psychological distress, use of standardized measures of infant cognitive functioning, and failure to take into account potential gender differences. Ninety‐nine twin pairs and both their mothers and fathers were assessed. Infants cognitive functioning was assessed using an infant‐controlled habituation–recovery–dishabituation task. Maternal and paternal psychological distress was assessed using the Symptom Check List‐90‐Revised. No gender differences were obtained for infant visual information‐processing abilities or parental psychological distress. Maternal and paternal psychological distress was related to female visual encoding abilities only. It was concluded that parental psychological distress might degrade parent–infant interactions. Characteristics of girls when faced with parents exhibiting psychiatric difficulties may exacerbate difficulties of parent–infant interactions, thereby hindering the full development of cognitive abilities involved in the process of habituation. A need exists to examine the relationship between parental psychological distress and infant visual attention separately for girls and boys. ©2001 Michigan Association for Infant Mental Health. 相似文献

Following a “failed” birth plan, some women experience trauma. Because most of these women do end up with a healthy baby, their support system does not necessarily support the sadness felt at the loss of the dream birth experience, leading to disenfranchised grief. Comments on a Facebook post linked to an essay from the Scary Mommy website were examined. Thematic analysis revealed three overarching categories of comments: (a) grief is disenfranchised by others through nonlosses and one-upping; (b) other posters expressed camaraderie for the loss of a dream birth, expressing empathy; and, (c) conditional support. 相似文献

Configural relations and a critical band of spatial frequencies (SFs) in the middle range are particularly important for face recognition. We report the results of four experiments in which the relationship between these two types of information was examined. In Experiments 1, 2A, and 2B, the face inversion effect (FIE) was used to probe configural face encoding. Recognition of upright and inverted faces and nonface objects was measured in four conditions: a no-filter condition and three SF conditions (low, medium, and high frequency). We found significant FIEs of comparable magnitudes for all frequency conditions. In Experiment 3, discrimination of faces on the basis of either configural or featural modifications was measured under the same four conditions. Although the ability to discriminate configural modifications was superior in the medium-frequency condition, so was the ability to discriminate featural modifications. We conclude that the band of SF that is critical for face recognition does not contribute preferentially to configural encoding. 相似文献

The Iowa Gambling Task (IGT) is widely used to assess decision making under conditions of uncertainty in clinical as well as in nonclinical populations. However, there is still debate as to whether normal performance at this task relies on implicit, emotion-based processes that are independent of working memory. To clarify the role of working memory on normal performance on the IGT, participants performed the task under low or high working memory load. We used a modified version of the original task, in which the position of the four decks was randomized between trials. Results showed that only participants performing under low memory load significantly chose more advantageously halfway through the task. In addition, when comparing the number of cards chosen from the two decks with frequent losses, one advantageous and one disadvantageous, only participants performing under low memory load chose more cards from the advantageous deck. The present findings indicate that the processes underlying optimal advantageous performance on the IGT rely on working memory functions. 相似文献

Retinoid signaling has been recently shown to be required for mnemonic functions in rodents. To dissect the behavioral and molecular mechanisms involved in this requirement, we have analyzed the spatial and recognition working memory in mice carrying null mutations of retinoid receptors RARbeta and RXRgamma. Double mutants appeared deficient in spatial working memory as tested in spontaneous alternation in the Y-maze and delayed nonmatch to place (DNMTP) test in the T-maze. These mutant mice did acquire, however, spatial place reference or right/left discrimination tasks in the T-maze set-up, indicating that basic sensorimotor functions, spatial orientation, and motivational factors are unlikely to account for deficits in working memory-sensitive tasks. Double-mutant mice were also deficient in novel object recognition at intermediate, but not short delays. RXRgamma appeared to be the functionally predominant receptor in modulation of the working memory, as RXRgamma, but not RARbeta single null mutant mice exhibited deficits similar to those observed in the double mutants. The mechanism of this modulation is potentially related to functions of RXRgamma in frontal and perirhinal cortex, structures in which we detected RXRgamma expression and which are functionally implicated in working memory processes. 相似文献

One hundred and twenty three practicing psychologists completed surveys regarding the therapeutic techniques they employ for
patients with Borderline Personality Disorder (BPD). Participants identified their predominant orientation and rated the frequency
with which they used a range of 27 specific strategies. Logistic regression analyses identified an expected relationship between
specific techniques and the theoretical orientations to which they are most closely linked. These findings suggest a high
level of concordance between self-described theoretical orientation and the specific treatment techniques utilized, but also
that some theoretical orientations are comprised of smaller independent clusters of strategies. The implications of these
findings are discussed. 相似文献
