哲学的终结：对一场针锋相对的争论的剖析

一、引言 当今许多预言家宣布说,哲学的终结即将到来.他们以多种声音、语言和语调传播他们的断言.尽管他们在意识形态和地理上参差不齐,但他们似乎享有一个共同的思路.     

Perceived family environment as a moderator of young adolescents' life stress adjustment

A longitudinal design was employed to test the main and stress-moderating effects of young adolescents' perceived family environment (Family Environment Scales; FES; Moos & Moos, 1981) on their depression, anxiety, and self-esteem. This study was part of a larger longitudinal project (L. Cohen, Burt, & Bjorck, 1987) that demonstrated the significant cross-sectional effects of the young adolescents' controllable and uncontrollable negative events, and the significant longitudinal effects of the former. The present cross-sectional analyses demonstrated the hypothesized main effects of the FES scores; families perceived as cohesive, organized, and expressive were related to positive psychological functioning, whereas families perceived as conflict-ridden and controlling were related to negative functioning. However, in general these effects were nonsignificant in the longitudinal analyses. Although there were a number of significant Negative Events x FES interactions, in no instance did the pattern support the hypothesized stress-buffering role of positive family climate.     

Attempted suicide in youth: Its relationship to school achievement,educational goals,and socioeconomic status

Twenty-six suicide attempters, 9 to 18 years of age, were compared with 725 nonattempters on measures of school achievement, educational goals, socioeconomic status, and depression. As has been found in studies using clinical samples, suicide attempters in our communitybased sample had significantly lower school achievement than nonattempters. The relationship between attempted suicide and low school achievement seemed to be explained by the effects of depression. Lower-SES youth tended to be more likely to attempt suicide than higher-SES youths. However, SES appeared to have little effect on the relationship between attempted suicide and school achievement. Results also suggest that children of mothers with low educational goals for them may be more at risk for attempted suicide than youths whose mothers have higher educational goals for their children.This research was supported by the National Institute of Mental Health, Grant No. MH36971.     

Strength of scopolamine-induced amnesia as a function of time between training and testing

Variations in the strength of scopolamine-induced amnesia as a function of age of the habit were studied in Swiss Webster mice. Animals were trained in an active avoidance task to a criterion of 9/10 avoidances and immediately following training injected with scopolamine hydrochloride (1.0 mg/kg) or saline. Retention of the avoidance learning was evaluated by testing different groups of animals 1, 3, 7, 10, 14, and 28 days following training. The retention test consisted of five trials in which the CS but not the UCS was presented. Results indicated that saline-treated mice exhibited near-perfect retention up to 14 days post-training with forgetting beginning to be apparent at 28 days. Scopolamine treatment produced strong amnesia in animals tested 1 and 3 days post-training but normal retention in animals tested 7 and 10 days after learning. The amnesia abruptly reappeared at 14 days after which time it remained stable. The marked similarity of the scopolamine retention curve to changes in the strength of memory of discrimination learning in undertrained rats reported by Deutsch suggested that scopolamine resulted in the storage of a weak memory of the avoidance response. To explore this idea further we trained mice to a criterion (4/5) which would result in a weak avoidance response and tested different groups 1, 3, 10, 14, and 28 days following learning. Results showed that strength of the memory of avoidance learning increased up to 10 days and then decreased abruptly at 14 days thus replicating the general shape of the retention curve produced by injecting scopolamine following strong training. These data suggest that scopolamine disrupts processes essential for the formation of durable memories.     

Some Legal Issues in Counselling and Psychotherapy

Although substantial legal difficulties can face anyone trying to recover compensation from counsellors for breach of their legal duties, such claims can in principle succeed. Counsellors ought to take particular care to provide a physically safe setting for the counselling session. Advice given to the client can lead to liability both to the client and to third parties who may be affected. The impact of the client's actions on third parties can justify, and less often compel, departures from confidentiality. The importance of keeping client records has to be balanced against legal obligations imposed on counsellors in various situations to make such records available for inspection by the client or third parties.     

Marital satisfaction and family stress as predictors of classroom behaviors

The purpose of this research was to examine the relationship between parents' perceptions of marital satisfaction and family stress and their third grade children's classroom behavior. Twenty-one married couples completed questionnaires during home visits. Behavior observations were made from videotapes of children recorded in their classroom during lunch and group academic periods on each of three days. Frequencies of peer interactions, solitary behaviors, and teacher interactions were coded. Regression analyses showed that mothers' level of marital satisfaction (but not fathers') predicted their children's frequency of peer interactions during lunch. Fathers' level of perceived family stress (but not mothers') predicted their children's frequency of peer interactions during lunch. Neither measure for either parent was related to the frequency of peer interactions, solitary behaviors, or teacher interactions observed during the academic sessions. These findings highlight the importance of assessing the potential differential relation of parent variables to children's trans-situational behaviors, and the examination of these variables in relation to different social-environmental contexts in which children participate outside the home.
