The separate and combined effects of covert and overt rehearsal in developing assertive behavior

The present investigation evaluated the separate and combined effects of covert modeling and overt rehearsal as a means of developing assertive behavior. Nonassertive clients (n = 66) received one of three treatments: covert modeling, overt rehearsal and covert modeling-overt rehearsal combined. A delayed-treatment group was included in the design to serve as a no-treatment control condition before clients were reassigned randomly to one of the three treatments. Treatments led to significant improvements on self-report and behavioral measures of assertiveness and self-efficacy. Although covert and overt rehearsal treatments were equally effective, the combined procedure led to significantly greater improvements which were evident at posttreatment and at an 8-month follow-up assessment. Treatment effects generalized to novel role-play situations and brought clients to the level of other persons who regarded themselves as adept in social situations requiring assertive behavior.     

Effects of covert modeling and coding of modeled stimuli on assertive behavior.

The present investigation examined the effects of covert modeling in developing assertive behavior and the effects of verbal coding of the modeling stimuli on treatment outcome. In a 2 × 2 design, modeling (imagining an assertive model versus imagining scenes without an assertive model) and summary coding (developing verbal codes of the modeled material versus not developing codes) were combined. The results indicated that modeling and coding enhanced behavior change across self-report inventories and a behavioral role-playing test. Superior performance on these measures was achieved by the modeling group that both imagined an assertive model and engaged in summary coding. These effects transferred to novel role-playing situations at post-treatment and were maintained at a 6-month follow-up assessment. The results suggest that coding of treatment stimuli affects acquisition and maintenance of the modeled behaviors in treatment in a way that resembles findings from laboratory research on modeling.     

Assertion modeling and stimuli effects on assertive behavior and self-efficacy in adolescents

The present investigation examined variations of modeling and stimuli with 61 adolescents selected for unassertive or aggressive behavior toward teachers. A 3 × 2 × 2 factorial design evaluated the effects of type of assertion modeling (three sessions of overt vs covert vs no-modeling), type of training stimuli (single involving teachers only vs multiple involving teachers, parents and peers) and type of initial behavior (unassertive vs aggressive) on behavioral role-play and self-efficacy. Modeling, particularly overt modeling, improved assertive behavior in teacher situations, peer situations and total teacher, parent, and peer situations. The use of single type stimuli improved self-efficacy in total teacher, parent and peer situations, and in novel situations involving others. Behavior but not self-efficacy was differentially affected by initial unassertive or aggressive behavior of participants. Self-efficacy and behavior were only moderately correlated. Results suggest effectiveness of short-term modeling with adolescents and different specificity properties of self-efficacy and assertive behavior.     

The money attitude of covert and overt narcissists

The money attitude of covert and overt narcissists was studied. Both covert and overt narcissism predicted the power-prestige dimension of money attitude, which were both mediated by the need for social power. Interestingly, the relationship for covert narcissism was also mediated by the fear of negative social evaluation, confirming its socially vulnerable and hypersensitive features. In addition, the anxiety and distrust factors of money attitude were correlated with covert narcissism only. Anxiety was explained by the need for power and avoidance motivation, but no significant mediator was found for distrust. These findings provide evidence to the similarities and differences between the two types of narcissism. They also shed light on narcissists’ money-related behaviors, such as investment strategy and consumer behaviors.     

Covert and overt rehearsal and elaboration during treatment in the development of assertive behavior

The present investigation examined the effects of covert and overt rehearsal and client elaboration of situations designed to train assertive behavior. Nonassertive clients (n = 61) received one of four treatments resulting from the 2 × 2 factorial combination of Modality of Rehearsal (covert vs overt) and Elaboration (elaboration vs no elaboration of training situations). A delayed-treatment group was included in the design to serve as a no-treatment control condition before subjects were assigned randomly to one of the above treatments. Treatment led to significant improvements on self-report and behavioral measures of assertiveness and self-efficacy. Covert and overt rehearsal were equally effective. However, elaboration of training situations significantly enhanced the effects of covert and overt rehearsal. Treatment effects were maintained up to a 6-month follow-up, transferred to novel role-playing situations, and brought clients within the range of other subjects (n = 45) who regarded themselves as adept in social situations requiring assertive behavior and who had not sought treatment.     

The effects of situational variations in role-play scenes on assertive behavior

The study was conducted to determine the extent to which variations in the situational parameters of role-play scenes affect subjects' levels of assertiveness. Thirty-six psychology undergraduate students were randomly assigned to one of three role-play conditions that differed in the situation-setting characteristics presented in the scenes: a Difficult condition, designed to inhibit assertive responding; an Easy condition, designed to facilitate assertive responding; and a Neutral condition. Subjects also completed a self-report assertion inventory. Videotapes of the role-played interactions were rated for a variety of component responses. Results indicate that subjects responded differently in the three conditions. Subjects in the Difficult and Neutral conditions were more compliant, and those in the Easy and Difficult conditions were more fluent. It is suggested that failure to specify the situational parameters of role-play scenes may affect the validity of this assessment procedure.This research was supported in part by NIMH Grant, MH28279 to the third author.     

Effects of practice, instructions, and modeling on components of assertive behavior

Unassertive psychiatric patients matched on age, years of education, diagnosis, and self-reported assertiveness were assigned to one of five conditions, with 10 subjects in each group: (1) Test-Retest, (2) Practice-Control, (3) Instructions, (4) Modeling, (5) Modeling plus Instructions. All subjects were videotaped (Pre- and Post-Test) while responding to five interpersonal situations requiring assertive responses. Pre- and Post-Test responses for all subjects were rated independently by judges on seven verbal and non-verbal components of assertiveness. Analyses of variance for difference scores followed by multiple t-test comparisons indicated that the Modeling plus Instructions group was superior or equal to the Instructions alone or Modeling alone groups on five of the seven components. Instructions alone and Modeling alone led to greatest improvement in the remaining two components. No differences were found between the Practice-Control and Test-Retest groups on any of the seven components of assertiveness. No differences (Post-Pretest) were found among the groups on a self-report measure of assertiveness.     

The relationship between covert and overt attention in endogenous cuing

In a standard Posner paradigm, participants were endogenously cued to attend to a peripheral location in visual space without making eye movements. They responded faster to target letters presented at cued than at uncued locations. On some trials, instead of a manual response, they had to move their eyes to a location in space. Results showed that the eyes deviated away from the validly cued location; when the cue was invalid and attention had to be allocated to the uncued location, eye movements also deviated away, but now from the uncued location. The extent to which the eyes deviated from cued and uncued locations was related to the dynamics of attention allocation. We hypothesized that this deviation was due to the successful inhibition of the attended location. The results imply that the oculomotor system is not only involved during the endogenous direction of covert attention to a cued location, but also when covert attention is directed to an uncued location. It appears that the oculomotor system is activated wherever spatial attention is allocated. The strength of saccade deviation might turn out to be an important measure for the amount of attention allocated to any particular location over time.     

Mother-child interactions in ADHD and comparison boys: Relationships with overt and covert externalizing behavior

Reciprocal relationships between child characteristics and such familial factors as parental psychopathology and interaction style with the child characterize the development and maintenance of attention-deficit hyperactivity disorder (ADHD) as well as its comorbidity with antisocial behavior. Our goal was to ascertain the ability of negative maternal behavior exhibited during mothers-on interactions to predict independently observed overt and covert externalizing behavior in the child, controlling for current maternal symptomatology and the boy's acting out behavior during the interaction. Participants were 49 boys with ADHD and 37 comparison boys, aged 6 to 12 years. Hierarchical multiple-regression analyses revealed that, even with maternal psychopathology and child negativity with the mother partialed, maternal negative behaviors predicted both observed noncompliance exhibited in class and play settings and laboratory stealing. Stealing was predicted from maternal negativity even with child interactional compliance controlled. Differential predictions of noncompliance were revealed in ADHD versus comparison families, yet similar patterns emerged for stealing within each group. Results are discussed in light of the high risk for antisocial behavior in ADHD children.This article is based, in part, on a doctoral dissertation written by Carolyn A. Anderson at the University of California, Los Angeles. The research received primary support from National Institute of Mental Health Grant 45064, awarded to Stephen P. Hinshaw. Partial support was received from the Fernald Child Study Center of the University of California, Los Angeles, where the 1990 summer research program was housed, and from a Faculty Research Grant to Stephen P. Hinshaw from the University of California, Berkeley. We express our deep appreciation to the many behavior observers and research staff, too numerous to mention individually, who were essential in collecting and coding the primary data for the study, and to the children and families who participated in the family assessments and summer research programs.     

Dissociation of covert and overt spatial attention during prehension movements: Selective interference effects

In four experiments, the influence of distractor objects on the temporal evolution of the reach-tograsp movement toward a target object (an apple) was examined. In the first experiment, the distractor was another apple, which moved laterally behind the target and occasionally changed direction toward the target, thus becoming the to-be-grasped object. In the second and third experiments, the distractor was a stationary piece of fruit, which sometimes became the to-be-grasped object because of a change in illumination. The fourth experiment was a combination of the first two experiments. In all cases, selective interference effects on the transport and manipulation components were observed only when attention to the distractor was covert rather than overt. It is proposed that covert visuospatial attention selects information about distracting but potentially important stimuli, such that a registration of significance is accomplished without the need to process all available information.     

Multichannel fNIRS assessment of overt and covert confrontation naming

Confrontation naming tasks assess cognitive processes involved in the main stage of word production. However, in fMRI, the occurrence of movement artifacts necessitates the use of covert paradigms, which has limited clinical applications. Thus, we explored the feasibility of adopting multichannel functional near-infrared spectroscopy (fNIRS) to assess language function during covert and overt naming tasks. Thirty right-handed, healthy adult volunteers underwent both naming tasks and cortical hemodynamics measurement using fNIRS. The overt naming task recruited the classical left-hemisphere language areas (left inferior frontal, superior and middle temporal, precentral, and postcentral gyri) exemplified by an increase in the oxy-Hb signal. Activations were bilateral in the middle and superior temporal gyri. However, the covert naming task recruited activation only in the left-middle temporal gyrus. The activation patterns reflected a major part of the functional network for overt word production, suggesting the clinical importance of fNIRS in the diagnosis of aphasic patients.     

Independent effects of achievement motivation and overt attribution on achievement behavior

The cognitive attribution theory of achievement motivation was examined in a series of three studies. The persistence of performance under failure feedback was investigated, with improvement over trials on a digit-symbol substitution task constituting the measure of persistence. Although evidence was obtained relating overt causal attributions of failure to persistence, partial correlation statistics indicated that this relationship was independent of achievement motivation. Partial correlation statistics also revealed that the relationship between achievement motivation and persistence was independent of attributional variables. In addition, greater persistence was exhibited by high- than by low-achievement subjects in the absence of attribution differences between these groups. Additional evidence was collected suggesting that the act of overt attribution was an ego-involving operation that led to these achievement differences in improvement. In general, achievement classification and overt causal attributions had separate effects on persistence, precluding the interpretation of achievement-related behavior in terms of attribution theory. Overt causal attributions were found to be, in part, a function of the ego-involving character of the task instructions, as was improvement.Portions of this research were conducted while L. A. White was supported by a Purdue University David Ross Research Fellowship; Kay Deaux, principal investigator.     

Switching time between overt and covert speech: Generative attention

Four experiments investigated a new phenomenon: the existence of a very large switching time effect that occurs from rapidly alternating between overt and covert (mouthed) speech. This is referred to as an intensity switching effect, and the time taken for each switch is, in itself, long enough for a spoken or mouthed character (letter or digit) to be produced. In Experiments 1 and 2, the intensity switching effect was shown to be different from the switching that occurs between categories of materials (letters and digits) because it is both much larger and much more resistant to practice effects. The intensity switching effect was also shown to be distinct from a memory load effect, since it holds even for perceptually available lists. In Experiments 3 and 4, the issue of a peripheral vs. a central origin of intensity switching was addressed. Evidence was found for a central origin. In addition, two models -of response intensity representation were contrasted: a symbolic or digital model, with intensity altered by parameter substitution, and an analog model, with intensity represented by a moving pointer on an intensity continuum. The results supported the symbolic model. It is concluded that the intensity switching effect is a measure of control processes at work in altering the intensity parameters of the vocal response system.     

Effect of name agreement on prefrontal activity during overt and covert picture naming

In recent neuroimaging studies, various tasks have been used to examine prefrontal cortex involvement in semantic retrieval and selection. One such task, picture naming, has yielded inconsistent results across studies. One potential explanation for this inconsistency is that the magnitude of prefrontal activity during picture naming depends on the extent to which a given picture evokes a single reliable meaning. To test this hypothesis, fMRI activity in the prefrontal cortex was measured while subjects named pictures with either high or low name agreement. In Experiment 1, subjects named black-andwhite line drawings, either covertly or overtly. Across both modalities, we found more left inferior frontal gyrus (LIFG) activity when the subjects named low-agreement pictures than when they named high-agreement pictures. No significant difference in head movement was detected between the two modalities. In Experiment 2, we replicated the effect of name agreement on LIFG activity during picture naming, using black-and-white photographs. These results provide further support for the idea that the LIFG mediates selection among competing alternatives and suggest a means for understanding the naming deficits observed in nonfluent aphasia.     

Development of covert and overt hostility scales from the Buss-Durkee Inventory

The purpose of this study was to develop covert and overt hostility scales from the Buss-Durkee Inventory. First, 22 covert hostility and 29 overt hostility items were identified by the authors. Second, an item analysis was done to assess the content saturation of the individual items on these scales. This analysis yielded the final form for 7 items for covert hostility and 14 for overt hostility. Cronbach alphas for the covert and overt scales were .67 and .77, respectively, and their intercorrelation was .08. Correlations for these Buss-Durkee scales with several existing measures of anger expression were consistent with expectations.
