Lists of 30 monosyllabic words drawn at random with replacement from a set of 69 were presented monotically to the right or left ear of 28 subjects for immediate repetition (shadowing) at a rate of 120 words per minute. Each subject shadowed 40 lists. A right-ear advantage was found over the first 1.5 blocks (15 lists) but not for the remaining 2.5 blocks (25 lists). The results are related to previous investigations of monotic and dichotic listening, and are explained by a set (bias) in attention or response which favours the right ear and declines with practice. 相似文献

Counselors need to be aware of the characteristics of men, the qualities of men in counseling, and the pressures on the contemporary man. This article considers some of the expectations and qualities of men in general and in the counseling relationship in particular. The influence of these qualities and expectations on the interaction between client and counselor is examined. Suggestions are made to improve the effectiveness of the counseling process. 相似文献

Seven experiments were addressed to the general question of whether the identification of letters and numbers is a more rapid process than the categorization of such stimuli. Subjects were required to make a single response if a target stimulus specified by name (e.g., “A,” “2”) or designated by category class alone (e.g., “letter,” “number”) was presented in a trial. The principal findings were: (1) identification reaction times (RTs) were faster than categorization RTs: (2) RTs for targets shown without a context were faster than RTs for targets shown in the context of other stimuli; (3) identification RTs for targets shown in the context of stimuli from a different conceptual-taxonomic category were faster than RTs for targets shown in the context of stimuli from the same category only when target-context stimulus discriminability differencet were optimized. The results were interpreted in terms of a two-stage processing model in which context face,ors affect the duration of an initial encoding-scanning stage and search instruction (effective memory size) factors affect the duration of the memory comparison stage. 相似文献

Nicotine is a paradoxical drug in that it both stimulates and depresses functions. It affects the central nervous system, the peripheral nervous system, the cardiovascular, the skeletal, and the gastrointestinal systems. Its psychoactive effects and drug dependency potential as well as some therapeutic approaches to smoking cessation have been reviewed here. More research information is needed for professionals working with those who want to quit smoking. 相似文献

The Newborn Behavioral Observations (NBO) system is a relationship-based tool that helps parents recognize their infant's competencies and learn their behavioral cues, with the goals of enhancing parental responsiveness and satisfaction in the infant-parent relationship. In our study, a pediatrician integrated the NBO into 44 pediatric health care visits of infants in rural Pakistan villages, under the remote guidance of two U.S.-based child psychiatrists. A clinician then gave the mothers a survey about their experience of the NBO and found that the mothers were highly satisfied, reporting greater appreciation of their infant's strengths, greater understanding of their infant's behavioral cues, stronger attachment to their infant, and greater self-confidence as a mother. In their consideration of these results, the authors explore cultural reasons for the mothers’ responses and generate hypotheses to inform an outcome study of a similar intervention. This was a feasibility and acceptability study and was not randomized, had no control group, and did not use objective measures of outcome. 相似文献

The HIV-1 transgenic (Tg) rat model is valuable for understanding HIV-associated neurocognitive disorders (HAND) and accompanying substance use and misuse. Tg and F344/NHsd wildtype (WT) rats were allowed to self-administer intrajugular cocaine. For the first 7 sessions, neither genotype self-administered cocaine (0.1 mg/kg/infusion) on a fixed ratio 1 schedule. We thus implemented a lever–cocaine “autoshaping” session followed by a series of manipulations changing dose and reinforcement schedule. Tg rats self-administered much less cocaine than WT rats throughout the study. Of 8 Tg rats, 5 modestly increased self-administration from sessions 36–50. Of those, only 3 showed a lever discrimination. Of 10 WT rats, 8 acquired robust self-administration by session 19; all WT rats self-administered cocaine by the end of the study. WT and Tg rats had similar baseline locomotor activity in the self-administration chamber suggesting that the low levels of cocaine intake in the Tg rats did not reflect a nonspecific motor impairment in this rat strain. Concomitant measurement of activity with self-administration revealed activity increases that followed increased cocaine intake. That relation held in Tg rats. Therefore, the present study provides evidence that HIV-1 Tg rats are less sensitive to the reinforcing effects of cocaine than their F344 WT counterparts. 相似文献

Matching the emotional expressions of pairs of face photos was slower with pixelated and blurred photos than with original, untransformed photos. Matching the identities of the same face pairs was unaffected by pixelation and blurring. Because pixelation and blurring degrade higher spatial frequencies carrying edge-based information that define feature shape more than lower frequencies carrying configural properties, these findings converge with findings for line drawings and negative photos in showing that expression and face recognition processes differ in their reliance on edge-based and configural information. 相似文献

Five adult humans were tested for emergent conditional discriminations under rapid-responding contingencies. During four-comparison matching-to-sample baseline training (AB and AC), limited-hold contingencies for responding to samples and comparisons were gradually restricted to the shortest duration consistent with at least 95% accuracy and no more than 5% failures to respond. The final limited-hold values were 0.4-0.5 s for samples and 1.2-1.3 s for comparisons; mean response latencies were 0.15-0.28 s for samples and 0.59-0.73 s for comparisons; inter-trial intervals were 0.4 s. With these fast-responding requirements, test blocks presented 72 probe trials interspersed among 72 baseline trials, all without programmed differential consequences. Four equivalence test blocks (BC and CB probes, which tested simultaneously for both symmetry and transitivity) were followed by four symmetry (BA and CA probes) test blocks. Three subjects' results documented emergent performances indicative of equivalence classes despite fast-responding requirements that severely limited the time available for mediating vocal or subvocal responses. For these three subjects, mean latencies were slightly shorter in baseline trials than in probes, and shorter on symmetry than on equivalence probes. These differences, however, were usually less than the differences among mean latencies on the different types of trials within the baseline and probed performances. 相似文献
