Specificity of reference patterns in depressive thinking: agency and object roles in self-representation

This study investigated A. T. Beck's (1970) negative cognitive triad as a model of depressive thinking. A mixed clinical sample (N = 126) completed the Sentence Completion Test for Depression (SCD) and self-report measures of depression and anxiety. Two reference patterns were tested: agency roles, people who are the source of thoughts, feelings, and actions (self and others); and object roles, points of reference location (self, other, world, future, and past). Cognitive effects were highly specific to depression. With self in agent role, significant correlations were observed with negative self, world, and future references but not with other people or the past. With others in agent role, only negative self references were correlated with depression (e.g., "Some people would not ... put me out if I was on fire"), suggesting an interpersonal extension to the negative cognitive triad.     

Adaptation to optically produced curvature of frontal planes

Attention, Perception, & Psychophysics - A new kind of adaptation was discovered, namely, to glasses that cause frontal planes to appear concave. The effect of this adaptation can be observed...     

Basing the treatment of stereotypic and self-injurious behaviors on hypotheses of their causes.

Stereotypic and self-injurious behaviors are common forms of maladaptive responding demonstrated by severely handicapped persons. Various review papers suggest that no single treatment procedure is universally effective. Although there may be many reasons for this finding, one could be that people engage in these behaviors for various reasons, and that procedures that are incompatible with the cause of the behavior are unlikely to be effective. These studies also suggest many hypotheses for the development and maintenance of these behaviors, three of which are the self-stimulation, positive reinforcement, and negative reinforcement hypotheses. The purpose of this paper was to determine whether one of these hypotheses could be matched to the cause of the behavior and used as an effective treatment procedure. We therefore compared one hypothesis with one other for 3 subjects in a three-phase study. During baseline, data were taken in two classrooms for each subject, and a judgement was made about the hypothesis most likely to be related to the cause of the behavior. During the second phase, a treatment based on that hypothesis was used in one classroom, and a treatment based on another hypothesis was used in the second classroom. During the third phase, the treatment that was most effective in the second phase was used in both classrooms. Results showed that a successful treatment program can be developed on an hypothesis of why the behavior occurred during baseline. Results are discussed in terms of supporting the argument that treatment programs should be based on a functional analysis of the behavior in its environmental context.     

Flight-skill decay and recurrent training

This article addresses the problem of flight-skill decay. The complexity of the problem is outlined with regard to identifying the nature and extent of decayed skills. It is suggested that cognitive/procedural skills are more prone than control-oriented skills to decay over periods of disuse. Effective recurrent training methods offer the most promise in forestalling loss of proficiency. Several such methods are described, and the importance of cognitive training is emphasized. Finally, criteria are noted for evaluating the utility of recurrent training media. The theories and practical measures discussed apply to many skills other than those of flying.     

Social networks and adult social identities: Profiles and correlates of support and rejection

The growth of interest in social networks has underscored the need for integrative analyses of network dimensions. A three-pronged strategy to achieve this objective was pursued in a study of 261 married women nurses. First, network variables related to important adult social identities were differentiated. Factor analyses revealed four network interaction factors: work support, work rejection, general support, and general rejection. An additional factor analysis differentiated work associates from nonwork network members. Second, cluster analysis of these factor scores identified five different network profiles. The profiles differed in the importance of the woman's work to her nonwork ties as well as the frequency and pattern of different positive and negative interactions. Third, individuals with these contrasting network profiles differed on levels of life satisfaction and psychological symptomatology. The discussion emphasizes social network differences within the broader context of the ecology of human development.     

Developmental differences in mental rotation.

A reaction time paradigm was used to investigate developmental differences in ability to rotate and compare imaginal representations. Third grade, fifth grade, and college students (ages 9, 11, and 20 years, respectively) were required to determine whether a letter of the alphabet was presented in its backward or normal position. Letters were presented at 0, 60, 120, 180, 240, or 300° orientations from upright. Subjects were given no advance information about a test letter, or they were given identity and orientation information. In the no information condition, reaction time increased for all age groups as a function of the departure in orientation of the test letter from an upright position. In the advance information condition, reaction time remained uniform across orientation for only the college subjects. The developmental implications of these findings are discussed.     

A simple technique for improving the quality of parameter estimates in learning hierarchy validation studies

Learning hierarchy research has been characterized by the use of ad hoc statistical procedures to determine the validity of postulated hierarchical connections. The two most substantial attempts to legitimize the procedure are due to White & Clark and Dayton & Macready, although both of these methods suffer from serious inadequacies. Data from a number of sources is analyzed using a restricted maximum likelihood estimation procedure and the results are compared with those obtained using the method suggested by Dayton and Macready. Improved estimates are evidenced by an increase in the computed value of the log likelihood function.
