Memory confusions for real and imagined completions of symmetrical visual patterns

In Experiment 1, subject ratings indicated that it was easier to imaginally complete half of a symmetrical form when the form was symmetrical about the vertical axis than when the form was rotated so that it was symmetrical about the horizontal axis. In Experiment 2, new subjects saw these same forms, some presented as wholes and some presented as halves. Compared with controls, subjects who were instructed to imagine the vertically symmetrical half forms as complete had more difficulty remembering which forms had been presented as wholes and which had been presented as halves. Imagery and control groups did not differ in ability to discriminate half from whole horizontally symmetrical forms. The results are consistent with predictions from Johnson and Raye’s (1981) reality monitoring model that discriminating memories of imagined and perceived events should be a function of the amount of cognitive operations included in the memory.     

The consequences for memory of imagining in another person’s voice

Subjects listened to and imagined words and then attempted to discriminate words they had heard from words they had imagined. Discrimination was better when subjects imagined themselves saying the words (Experiments 1 and 2) than when subjects imagined the words in the speaker’s voice. Subjects also had more difficulty discriminating imagined from perceived words when they imagined in the speaker’s voice than when they imagined words in a voice other than their own or the speaker’s (Experiment 1). The results are consistent with the idea that reality monitoring is affected by the degree of similarity in sensory characteristics of memories derived from perception and from imagination (Johnson & Raye, 1981).     

The Heart on the Sleeve and the Secret Self: Estimations of Hidden Emotion in Self and Acquaintances

ABSTRACT This research investigated how estimations of subjectively experienced emotion and estimations of displayed emotion varied with the familiarity of the target person Subjects imagined themselves, a close friend, a moderate friend, or a casual acquaintance in a series of brief affect-eliciting situations, and then estimated the degree to which the designated person would both feel and display specific emotions Subjects consistently estimated that people, including themselves, would feel more emotion than they displayed This discrepancy between experienced feeling and displayed feeling increased as a linear function of familiarity with the person The amount of undisplayed affect–the estimated “secret self”–was generally smallest for a casual acquaintance, greater for a moderate friend, still greater for a close friend, and greatest of all for the self The magnitude of this familiarity effect, however, varied with the social desirability of the emotion If an emotion was socially desirable, subjects estimated that familiar persons would both feel the emotion more and display it more than less familiar others would If an emotion was socially undesirable, subjects also estimated that familiar others would feel it more than unfamiliar others would However, they estimated that familiar and less familiar others would display socially undesirable emotions to about the same degree, and estimated that they themselves would display these emotions significantly less than others Consequently, although subjects always perceived     

Psychosocial Predictors of Young Adolescent Cigarette Smoking: A Sixteen-Month,Three-Wave Longitudinal Study1

Understanding the psychosocial factors that predict cigarette smoking onset in young people is of crucial importance for prevention efforts. The present study examined prospective psychosocial predictors of smoking in a three-wave longitudinal data set. Similar in design to an earlier study by Chassin, Presson, Sherman, Corty, and Olshavsky (1984), the present study replicated their work, and extended it by (a) using composite predictors derived from exploratory factor analysis, (b) including prior behavior as a predictor, (c) using a design extended over three waves of data collection, and (d) using a sample composed primarily of urban teenagers. Subjects were 3295 7th-grade students at the beginning of the study. The subjects completed a questionnaire containing items tapping cigarette smoking behavior and psychosocial items that have previously been shown to predict smoking behavior. Forty-one psychosocial items on the Wave 1 (initial) questionnaire were factor analyzed, and five factors were retained. Subscale scores were constructed based on these factors and were used as predictors. Regression analyses were performed using the subscales and pretest smoking frequency to predict a continuous measure of smoking, and discriminant analyses were performed to predict transitions between qualitative levels of smoking. Prior smoking behavior was the most important predictor of future smoking. Four of the subscales, Social Disapproval, Risk Taking/Rebelliousness, Perceived Smoking Prevalence, and Motivation to Comply, were significant predictors. One subscale, Physical Consequences from Smoking, was not predictive of smoking in any of the analyses. The effect sizes cross-validated well. It is suggested that an integrative model of smoking initiation developed by Flay, d'Avernas, Best, Kersell, and Ryan (1983) best summarizes the results of the present study.     

INCREASING THE INDEPENDENT RESPONDING OF AUTISTIC CHILDREN WITH UNPREDICTABLE SUPERVISION

We investigated the role of predictable versus unpredictable supervision on the independent task responding of three autistic children. In a predictable supervision condition, the therapist was present in the setting for a regular period of time and then was absent for the remainder of the session. In an unpredictable supervision condition, the therapist's presence was scheduled on a random, intermittent, and unpredictable basis throughout the session. The multiple baseline analysis showed that the unpredictable supervision produced much higher levels of on-task responding during the therapist's absence for all three children. Analysis of work completed during the therapist's absence also favored the unpredictable supervision condition. The results are discussed in relation to the literature on generalization and educational practice.     

Methylphenidate in hyperactive children: Differential effects of dose on academic,learning, and social behavior

Methylphenidate (Ritalin) has been shown to have differential effects on hyperactive children's behavior as a function of dose level. In the present investigation, a triple-blind, placebo-control, within-subject (crossover) experimental design was employed in which 12 hyperactive boys between 6 and 10 years received three different dosages of methylphenidate (5, 10, and 15 mg) in a randomly assigned sequence. Dosage effects were assessed on clinic(PAL-Paired Associates Learning test) and school-(percent on task, teacher ratings, work completion rates, and accuracy) related behaviors. For 10 of the children, classified as responders to medication by the PAL using the criteria of Swanson, Kinsbourne, and colleagues, a series of ANCOVAs with repeated measures showed significant dosage effects on teacher ratings (p 01), percent on task (p 01), academic accuracy (p 05), and assignment completion rates (p 05). PAL performance was also significantly enhanced (p 01) after optimal dose levels were considered. Subsequent trend analysis showed a significant positive linear relationship between dose and each of the dependent variables. A comparison of fixed-dose and miligram-per-kilogram plots showed that children's performance across the different dosages were clearly individualistic and task-specific, even when similar body weights were compared. The implications of using clinic-based testing to determine optimal medication responsivity were discussed.We would like to express our sincere appreciation to the following pediatricians for their valuable assistance: W.

Effects of the cognitive organization of route knowledge on judgments of macrospatial distance

The effects of route segmentation were examined in a series of three experiments, Subjects in Experiment 1 divided an actual route into segments. Subjects in Experiment 2 performed corresponding proximity-judgment and distance-estimation tasks involving locations selected on the basis of the route segments identified in Experiment 1. Subjects in Experiment 3 performed a simple unidirectional distance-estimation task. Results from these experiments indicated that subjects can readily divide a route into segments and that these segments significantly bias judgments of macrospatial distance. These findings suggest a similarity between route segmentation in macrospatial cognition and categorization in other cognitive-task domains.     

An investigation of the nomological network of social interest

This paper presents the results of three studies relating a composite measure of social interest to numerous variables within the nomological network of social interest. Study 1 found that social interest is positively related to sex-role femininity, androgyny, positive ambition, other-centered life goals, and, surprisingly, sex-role masculinity. Study 1 also found social interest negatively related to a narcissistic life goal, personality rigidity, and negative interpersonal behavior (Drivenness). Study 2 correlated social interest with the Personality Research Form and found, as expected, that social interest is correlated with the Affiliation and Nurturance scales. Unfortunately, social interest was not negatively related to Aggression. Finally, Study 3 provided generally positive support for the hypothesized relationships between social interest and several variables from the Life Styles Inventory (e.g., Humanism, Affiliation, etc.). Implications of the results for the construct validity of Adlerian social interest theory and current measurement of social interest are presented.
