Computer-based instruction (CBI) was used to teach 3 sets of 20 spelling words to two 6th graders in a multiple baseline design.
The CBI presented a voice recording of each spelling word and prompted the students to type the word. If they spelled the
word incorrectly, a training procedure was initiated that included prompt fading and systematic review practice. Results showed
that three to ten 15-min training sessions were needed for participants to score 100% on each word set. During a subsequent
maintenance phase, one participant received 2 re-training sessions on word Set 2 due to low performance but no other training
was provided. Average performance was 93% across all word sets during the final three sessions of the maintenance phase and
79% on a 3-week follow-up test.

We have previously shown that the extracellular signal-regulated kinase/mitogen-activated protein kinase (ERK/ MAPK) is transiently activated in anatomically restricted regions of the lateral amygdala (LA) following Pavlovian fear conditioning and that blockade of ERK/MAPK activation in the LA impairs both fear memory consolidation and long-term potentiation (LTP) in the amygdala, in vitro. The present experiments evaluated the role of the ERK/MAPK signaling cascade in LTP at thalamo-LA input synapses, in vivo. We first show that ERK/MAPK is transiently activated/phosphorylated in the LA at 5 min, but not 15 or 60 min, after high-frequency, but not low-frequency, stimulation of the auditory thalamus. ERK activation induced by LTP-inducing stimulation was anatomically restricted to the same regions of the LA previously shown to exhibit ERK regulation following fear conditioning. We next show that intra-LA infusion of U0126, an inhibitor of ERK/MAPK activation, impairs LTP at thalamo-LA input synapses. Collectively, results demonstrate that ERK/MAPK activation is necessary for synaptic plasticity in anatomically defined regions of the LA, in vivo. 相似文献

Moral phenomenology is (roughly) the study of those features of occurrent mental states with moral significance which are
accessible through direct introspection, whether or not such states possess phenomenal character – a what-it-is-likeness.
In this paper, as the title indicates, we introduce and make prefatory remarks about moral phenomenology and its significance
for ethics. After providing a brief taxonomy of types of moral experience, we proceed to consider questions about the commonality within and distinctiveness of such experiences, with an eye on some of the main philosophical issues in ethics and how moral phenomenology might be brought
to bear on them. In discussing such matters, we consider some of the doubts about moral phenomenology and its value to ethics
that are brought up by Walter Sinnott-Armstrong and Michael Gill in their contributions to this issue.

A study was conducted to assess accuracy of deliberate nonverbal communication of affective messages between individuals assigned to different power roles within dyads. In phase 1, participants (N = 158) were assigned to unequal- or to equal-power roles and asked to send positive, negative, and neutral messages to their partner using nonverbal cues while the partner guessed which kind of message it was. In phase 2, naïve decoders (N = 294) made judgments of the videotapes from phase 1 to resolve the confounding of sender and decoder factors in the within-dyad communication paradigm. Results showed that subordinates were more accurate at decoding superiors than vice versa, and that this difference was due to subordinates sending less clear messages to superiors than superiors sent to subordinates. Comparison with the equal-power group’s expressions revealed that the subordinates’ expressions were also less clear than those sent by the equal-power group. 相似文献

This study is the first to examine the latent structure of individual differences reflected in the Adult Attachment Interview (AAI; C. George, N. Kaplan, & M. Main, 1985), a commonly used and well-validated measure designed to assess an adult's current state of mind regarding childhood experiences with caregivers. P. E. Meehl's (1995) taxometric methods (i.e., MAXCOV-HITMAX) were applied to data from 504 AAIs. Analyses revealed that the variation underlying secure versus dismissing states of mind was more consistent with a dimensional than a taxonic model. (Taxometric analyses of preoccupation were indeterminate.) In addition, variation in secure adults' (n=278) reports about their early experiences revealed little evidence for qualitative groups of earned- and continuous-secures. Rather, the inferred life experiences of secure adults appeared to be distributed continuously. Findings are discussed in terms of their theoretical implications regarding the phenomenon of earned-security specifically and variation underlying secure and insecure states of mind more generally. The consequences of these analyses for AAI reliability training and coding are also explored. 相似文献

Nicotine replacement products are commonly used to promote smoking cessation, but alternative and complementary methods may increase cessation rates. The current experiment compared the short-term effects of a transdermal nicotine patch to voucher-based reinforcement of smoking abstinence on cigarette smoking. Fourteen heavy smokers (7 men and 7 women) completed the four 5-day phases of the study: baseline, patch treatment, voucher treatment, and return to baseline. The order of the two treatment phases was counterbalanced across participants. In the patch treatment condition, participants wore a 14-mg transdermal nicotine patch every day. In the voucher treatment condition, participants received vouchers contingent on abstinence from smoking, defined as producing carbon monoxide (CO) readings of < or =4 parts per million. Participants e-mailed two video clips per day showing them breathing into a CO monitor and the resulting CO reading to clinic staff. In the voucher treatment, 24% of samples were negative, and 5% of samples were negative in the patch treatment. Results suggest that contingent vouchers were more effective than transdermal nicotine patches in promoting abstinence. 相似文献

The phenomenology of the self includes the sense of control over one's body and mind, of being bounded in body and mind, of having perspective from within one's body and mind and of being extended in time. I argue that this phenomenology is to be accounted for by a set of five dissociable cognitive capacities that compose the self. The focus of this paper is on the four capacities that compose the synchronic self: the agentive(B) self, which underlies the sense of control over one's body; the boundary(B) self, which underlies the sense of being bounded within one's body; the agentive(M) self which underlies the sense of control over one's thoughts; and the boundary(M) self which underlies the sense of being bounded within one's mind. I model the agentive(B) and agentive(M) selves as parts of the motor control system and the boundary(B) self as the capacity to form and integrated map of the body. I point to the delusion of thought broadcast as a possible source of evidence for future research on the boundary(M) self. 相似文献

I included scores on the Antisocial Features (ANT) and Aggression (AGG) scales of the Personality Assessment Inventory (PAI; Morey, 1991) and ratings on the Lifestyle Criminality Screening Form (LCSF; Walters, White, & Denney, 1991) along with age and prior disciplinary record in a series of negative binomial regression analyses of total, nonaggressive, and aggressive incident reports (IRs) received in a 2-year follow-up of 120 male maximum security federal prisoners. Findings indicated that the AGG scale, but not the LCSF or ANT, predicted total and nonaggressive IR counts. The LCSF achieved significant receiver operating characteristic (ROC) results in predicting dichotomized aggressive IRs, the ANT achieved significant ROC results in predicting dichotomized total and nonaggressive IRs, and the AGG achieved significant ROC results in predicting all 3 dichotomized categories of IR. Supplemental analyses revealed that the AGG continued to predict total and nonaggressive IRs when the Psychological Inventory of Criminal Thinking Styles (PICTS; Walters, 1995) Proactive scale was included in the negative binomial regression but not when the PICTS Reactive scale was included in the negative binomial regression. 相似文献
