Seven squirrel monkeys (Saimiri sciureus) previously trained on reverse-reward tasks were presented with the original "1-versus-4" task after a 5-year interval without reverse-reward experience (Experiment 1). None of them reliably selected the smaller food array; however, at around chance level, their performance was superior to when they were first exposed to the task almost 6 years previously, suggesting some long-term memory retention. One naive monkey consistently selected the larger array, as expected. In Experiment 2, trials consisting of 1 versus 1 piece of two qualitatively different types of food were interspersed among familiar 1-versus-4 trials. None of five monkeys tested reliably selected the less-preferred food to get the more preferred food as the reward, and one monkey scored below chance. However, when one piece of low-preference food was paired with four pieces of high-preference food (Experiment 3), all four monkeys tested avoided reaching for the latter and thereby obtained it as the reward; two monkeys obtained perfect scores on these trials. These two monkeys were trained on a specific qualitative reverse-reward pairing and then again tested on new pairings (Experiment 4), but transfer was incomplete. Compound trials that pit quantity against quality in novel ways appear taxing for squirrel monkeys, despite competence in reverse-reward on both dimensions separately. 相似文献

A plausible explanation of the wrongfulness of threatening, advanced most explicitly by Mitchell Berman, is that the wrongfulness of threatening derives from the wrongfulness of the act threatened. This essay argues that this explanation is inadequate. We can learn something important about the wrongfulness of threatening (with implications for thinking about coercion) by comparing credible threats to some other claims of impending harm. A credible bluff threat to do harm is likely to be more and differently wrongful than making intentionally false warnings about other sources of harm. This essay surveys some examples to secure this point, shows that Berman's moralized account of their wrongfulness is wanting, and offers the outline of an approach better suited to explain the wrongfulness of threatening. 1 相似文献

This article describes the development of the Therapist Use-of-Self Orientation Questionnaire (TUSO-Q), an instrument designed
to measure therapists’ use-of-self orientations while working with clients. A total of 373 therapists participated in this
study. Exploratory factor analysis in the structural equation modeling context revealed three different therapist use-of-self
orientations: Transpersonal, Contextual, and Instrumental. The final model provided an excellent fit to the data. TUSO-Q scores
exhibited satisfactory evidence of internal consistency reliability and construct validity. Implications for the scale’s use
in clinical research and training are discussed. 相似文献

Despite widespread acknowledgment of the importance of online semantic maintenance, there has been astonishingly little work that clearly establishes this construct. We review the extant work relevant to short-term retention of meaning and show that, although consistent with semantic working memory, most data can be accommodated in other ways. Using a new concurrent probe paradigm, we then report experiments that implicate a semantic maintenance capacity that is independent of phonological or visual maintenance that may build on a mechanism of direct semantic maintenance. Experiments 1 through 5 established that while subjects maintain the meaning of a word, a novel delay-period marker of semantic retention, the semantic relatedness effect, is observed on a concurrent lexical decision task. The semantic relatedness effect refers to slowed response times when subjects make a lexical decision to a probe that is associatively related to the idea they are maintaining, compared to when the probe is unrelated. The semantic relatedness effect occurred for semantic but not for phonological or visual word-form maintenance, dissipated quickly after maintenance ends, and survived concurrent articulatory suppression. The effect disappeared when subjects performed our immediate memory task with a long-term memory strategy rather than with active maintenance. Experiment 6 demonstrated a parallel phonological relatedness effect that occurs for phonological but not semantic maintenance, establishing a full double dissociation between the effects of semantic and phonological maintenance. These findings support a distinct semantic maintenance capacity and provide a behavioral marker through which semantic working memory can be studied. 相似文献

A well-known eye movement paradigm combines saccades (fast eye movements) with a perceptual discrimination task. At a variable
time after the onset of a central arrow cue indicating the target direction [the stimulus onset asynchrony (SOA)], discrimination
symbols appear briefly at saccade target and non-target locations. A previous study revealed an unexpected effect of SOA on
saccadic latencies: latencies were longer in trials with longer SOAs. It was suggested that this effect reflects a top-down
process as observers may wait for the discrimination symbol to appear before executing saccades. However, symbol onsets may
also modulate saccade latencies from the bottom-up. To clarify the origin of the SOA effect on latencies in this paradigm,
we used a simplified version of the original task plus two new symbol onset conditions for comparison. The results indicate
that the modulation of saccadic latencies was not due to a top-down strategy, but to a combination of two opposing bottom-up
effects: the symbol onsets at the target location shortened saccade latencies, while symbol onsets at non-target locations
lengthened saccade latencies. 相似文献

While there has been steady progress in identifying psychophysiological traits associated with psychopathy, most of the existing research has been carried out using incarcerated male participants, and data that include females are particularly rare. This study examined both affective startle blink modulation and P3 amplitude in a sample of female undergraduates grouped by scores on the Psychopathic Personality Inventory-Revised (PPI-R). Those scoring high for psychopathic traits lacked startle blink potentiation and demonstrated larger P3 amplitudes during auditory and visual oddball tasks. These data support the generalizability of deficient startle potentiation to non-incarcerated females with psychopathic traits, and add to a growing body of literature suggesting that psychopathic traits are associated with distinctive information-processing characteristics as indexed by P3 amplitude. 相似文献

Thirty‐three families, each with a premature infant born less than 33 gestational weeks, were observed in a longitudinal exploratory study. Infants were recruited in a neonatal intensive care unit, and follow‐up visits took place at 4 months and 12 months of corrected age. The severity of the perinatal problems was evaluated using the Perinatal Risk Inventory (PERI; A.P. Scheiner & M.E. Sexton, 1991 ). At 4 months, mother–infant play interaction was observed and coded according to the CARE‐index (P.M. Crittenden, 2003 ); at 12 months, the Strange Situation Procedure (SSP; M.D.S. Ainsworth, M.C. Blehar, E. Waters, & S. Wall, 1978 ) was administered. Results indicate a strong correlation between the severity of perinatal problems and the quality of attachment at 12 months. Based on the PERI, infants with high medical risks more frequently tended to be insecurely attached. There also was a significant correlation between insecure attachment and dyadic play interaction at 4 months (i.e., maternal controlling behavior and infant compulsive compliance). Moreover, specific dyadic interactive patterns could be identified as protective or as risk factors regarding the quality of attachment. Considering that attachment may have long‐term influence on child development, these results underline the need for particular attention to risk factors regarding attachment among premature infants. 相似文献

The goal of this study was to investigate how parents’ engagement of their child in everyday decision-making influenced their adolescent’s development on two neuropsychological functions, namely, affective decision-making and working memory, and its effect on adolescent binge-drinking behavior.We conducted a longitudinal study of 192 Chinese adolescents. In 10th grade, the adolescents were tested for their affective decision-making ability using the Iowa Gambling Task (IGT) and working memory capacity using the Self-ordered Pointing Test (SOPT). Questionnaires were used to assess perceived parent-child engagement in decision-making, academic performance and drinking behavior. At one-year follow-up, the same neuropsychological tasks and questionnaires were repeated.Results indicate that working memory and academic performance were uninfluenced by parent-child engagement in decision-making. However, compared to adolescents whose parents made solitary decisions for them, adolescents engaged in everyday decision-making showed significant improvement on affective decision capacity and significantly less binge-drinking one year later.These findings suggest that parental engagement of children in everyday decision-making might foster the development of neurocognitive functioning relative to affective decision-making and reduce adolescent substance use behaviors. 相似文献

Recognition of multicultural competence as an essential component of ethical counseling practice is a growing trend. This article presents a historical perspective of salient events that have contributed to forging a link between multicultural competence and ethical behavior. Multicultural counseling is traced from its beginnings to its emergence at a position of prominence in the profession, along with the development of ethical guidelines over time. This time line depicts the infusion of multicultural considerations into ethical standards and provides a perspective for examining the current status of multicultural competence as an ethical mandate. Implications for the counseling profession are offered. 相似文献

Gender stereotyping and under-representation of girls and women have been documented in children’s picture books in the past, in the hope that improvements would follow. Most researchers have analyzed award-winning books. We explored sexism in top selling books from 2001 and a 7-year sample of Caldecott award-winning books, for a total of 200 books. There were nearly twice as many male as female title and main characters. Male characters appeared 53% more times in illustrations. Female main characters nurtured more than male main characters did, and they were seen in more indoor than outdoor scenes. Occupations were gender stereotyped, and more women than men appeared to have no paid occupation. Few differences were found between Caldecott award books and other books. A comparison of our book sample to 1980s and 1990s books did not reveal reduced sexism. The persistence of sexism in picture books and implications for children and parents are discussed. 相似文献
