The current literature suggests that individuals who chronically abuse alcohol exhibit a wide variety of cognitive deficits
resulting from cerebral dysfunction that is either directly or indirectly related to their alcohol consumption history. Cognitive
deficits have been hypothesized as having implications for standard alcohol treatment efficacy as they may directly affect
cognitively impaired individuals’ abilities to utilize various treatment modalities. Although evidence is accumulating that
suggests this is actually the case, the majority of alcohol treatment programs neither directly consider the impact cognitive
deficits have on treatment efficacy nor do they employ cognitive rehabilitation treatment strategies to remediate identified
cognitive deficits. Few studies exist that investigate the remediability of neurobehavioral deficits or the efficacy of integrating
cognitive rehabilitation strategies into more traditional treatment programs. Empirical investigations conducted to date indicate
that some cognitive deficiencies secondary to alcoholism are amenable to cognitive rehabilitation and this remediation is
generalizable. Rigorous well-controlled treatment outcome investigations are needed in order to determine the efficacy of
cognitive rehabilitation techniques in naturalistic settings using ecological outcome measures. Also, emphasis should be placed
on integrating cognitive rehabilitation techniques with proven efficacy into traditional alcoholism treatment programs. 相似文献

Recent work has sought to use the time at which the Lateralized Readiness Potential (LRP) first develops (LRP onset) as a temporal landmark to bisect experimental effects on reaction time (RT). Many studies have found experimental effects on the time between the signal and LRP onset, but few have found effects on the time between LRP onset and RT (LRP-RT interval). The primary goal of this study was to produce an effect on the LRP-RT interval. We employed precuing, a manipulation likely to influence motor-programming processes at the end of the RT interval. Subjects performed a 4-alternative choice-RT task in which a signal prompted a button-press with the index or middle finger on the left or right hand. Precues preceded the signals and were either informative, reducing the set of response alternatives from four to two, or uninformative. Besides RT and LRP, we also measured electromyographic (EMG) activity and the P300 ERP component. RT, P300 latency, and the interval between the signal and LRP onset were all shorter with informative than uninformative precues, but the timing of EMG activity relative to RT remained the same. Most importantly, precuing affected the LRP-RT interval. Implications for bisecting RT with LRPs and the identity of processes affected by precuing are discussed. 相似文献

A case study analyzed employees' attitudes toward, and experiences with, an intraorganizational electronic mail system. Results revealed that females perceived e-mail to be easier to use, more efficient, and more effective than males. They also gave higher ratings of appropriateness for using e-mail to transmit certain types of messages. Females (particularly managers) were more likely than their male counterparts to rely on co-workers to learn how to use e-mail. More females used the computer system for word processing, while more males and whites (who comprised 82.2% of the sample) had off-site connections to the computer system. No other distinctions were found regarding race—ethnicity. Implications for future research are discussed.The author is grateful to Karen Tracy, Robert Craig, and anonymous reviewers for their insights and suggestions. 相似文献

This process evaluation study examined what variables moderate and mediate treatment effects on days in stable housing and
client satisfaction for homeless mentally ill clients. In general, demographic characteristics did not moderate either outcome
variable. Housing contacts, entitlement contacts, mental health contacts, and supportive services were significant mediators
of the treatment effect on days in stable housing. Program contacts, mental health contacts, and supportive services were
significant mediators of client satisfaction.

A running-wheel-movement-detection system is described for use with an IBM-compatible system and a serial mouse. It is an adaptation of a system developed for use on a Commodore 64. The IBM-compatible system provides obvious advantages in speed, memory, data storage, and programming ease over the earlier Commodore 64 system. 相似文献

The possibility of using prerecorded words and 2-sec. delayed speech feedback as reinforcement in the reconditioning of intelligible verbal responses in a chronic, neologistic schizophrenic patient was investigated. A test situation was devised which involved daily presentation of 100 stimulus word-picture cards to elicit verbal responses. The results indicated that both singly presented prerecorded words and delayed speech feedback apparently strengthened correct and intelligible verbal responding. 相似文献
