Image Induction and Social Influence: Explication and Initial Tests

Image induction posits that social influencers can manipulate a target's self-image to gain increased compliance. By preceding a request with a question that creates a salient self-image in a target, targets are more likely to behave consistently with that image by complying with the request. Three studies provide empirical tests of image induction. Results indicate that the addition of an image-inducing pretreatment question is associated with increased rates of compliance when compared to a control group. These findings held across two types of image induction manipulations (helpfulness, willingness to try new things), two types of behaviors (agreeing to complete a survey, agreeing to receive a free soft drink sample), and both face-to-face and written requests.     

A Step‐by‐Step Guide to Using Secondary Data for Psychological Research

The purpose of this paper is to serve as a primer for those who have never used, or even considered using, secondary data as a resource for psychological research. Secondary data (SD) can provide a unique methodological tool with which to examine psychological issues and can serve as a valuable contribution to a program of research. However, this important resource may often be overlooked because its use can sometimes appear daunting and time‐consuming. We seek to assist new users of SD by describing the process in a step‐by‐step manner. We address both benefits and challenges to anticipate when using SD, and discuss identifying and acquiring potential datasets, creating a personalized dataset, variable creation, statistical considerations, and the potential problem of conflicting findings when large datasets are used by multiple researchers. Our goal is to encourage researchers who are novices to the approach to consider using SD as an adjunct to their program of research.     

An Experimental Analysis of the Effects of Reading Interventions in a Small Group Reading Instruction Context

The current study examined the effects of several combinations of instructional and motivational interventions on oral reading fluency in the context of small group reading instruction. A treatment package consisting of acquisition, fluency, and motivational components was examined and then dismantled. Results were evaluated individually for each participant using a multiple-probe design in order to identify the most effective, yet efficient reading intervention package for each member of the group. The results indicated that, although all potential combinations of the package were effective, the experimental analysis was able to identify an effective yet more efficient package that produced substantial increases in performance across all students. Results are discussed in terms of effective instructional components in small group instruction and how to adapt methods for the experimental analysis of behavior to make decisions about the effectiveness of small group instruction in reading.This study is based on a dissertation submitted by the first author in partial fulfillment of requirements for the doctoral degree.

Neuropsychological assessment with the Visual Gestalt Test: psychometric properties and differential diagnostic probabilities

The Visual Gestalt Test is a neuropsychological instrument developed for evaluation of learning and memory of visuo-spatial material. A revised strategy of scoring has motivated the present study, where data from 153 normal persons, 99 epilepsy patients, and 24 depressed patients are presented and compared. The Visual Gestalt Test is observed to discriminate between normal and diagnosed groups in several ways. Additionally it is found to discriminate between depressed and brain damage subgroups of patients. Data are presented in order to supplement previously published ways of scoring and norms. Practical guidelines for the clinical applications of the test are suggested as perspectives.     

Multidimensional set switching

The present study examined the organization of preparatory processes that underlie set switching and, more specifically, switch costs. On each trial, subjects performed one of two perceptual judgment tasks, color or shape discrimination. Subjects also responded with one of two different response sets. The task set and/or the response set switched from one to the other after 2-6 repeated trials. Response set, task set, and double set switches were performed in both blocked and randomized conditions. Subjects performed with short (100-msec) and long (800-msec) preparatory intervals. Task and response set switches had an additive effect on reaction times (RTs) in the blocked condition. Such a pattern of results suggests a serial organization of preparatory processes when the nature of switches is predictable. However, task and response set switches had an underadditive effect on RTs in the random condition when subjects performed with a brief cue-to-target interval. This pattern of results suggests overlapping task and response set preparation. These findings are discussed in terms of strategic control of preparatory processes in set switching.     

Hearing by eye: how much spatial degradation can be tolerated?

In the McGurk effect (McGurk and MacDonald, 1976 Nature 264 746-748), illusory auditory perception is produced if the visual information from lip movements is discrepant from the auditory information from the voice. A study is reported of the tolerance of the effect to varying levels of spatial degradation (videotaped images of a speaker's face were quantised by a mosaic transform). The illusory effect systematically decreased with an increase in the coarseness of the spatial quantisation. However, even with the coarsest level (11.2 pixels/face) the illusion did not completely disappear. In addition, those participants who did not experience the illusion nevertheless showed the effects of auditory-visual interaction in their clarity ratings of the auditory stimulus. It is concluded that auditory-visual interaction in visible speech perception is based on relatively coarse-spatial-scale information.     

The impact of past relationships on interpersonal behavior: behavioral confirmation in the social-cognitive process of transference

This study extended research on transference in social perception (e.g., S. M. Andersen, I. Reznik, & L. M. Manzella, 1996) into the realm of social behavior by examining behavioral confirmation (e.g., M. Snyder, 1992) in transference. Each perceiver participated in a brief conversation with a naive target participant, who either did or did not appear to resemble the perceiver's own positively or negatively regarded significant other. Trained judges rated positive affect expressed in targets' behavior. As predicted, targets expressed more positive affect in their behavior when they allegedly resembled the perceiver's own positively versus negatively toned significant other, an effect not found in the control condition. This evidence demonstrates behavioral confirmation in transference, suggesting a means by which present relationships may resemble past ones.     

The diagnostic efficiency of the Rorschach Depression Index and the Schizophrenia Index: a review

This review focuses on the diagnostic efficiency of the new versions of the Rorschach Comprehensive System Depression Index (DEPI) and the Schizophrenia Index (SCZI). Clinical diagnosis according to the Diagnostic and Statistical Manual of Mental Disorders was chosen as the external validation criteria. The sensitivity, specificity, and overall classification rates for the indices were presented from the studies or computed from the data when possible. The positive and negative predictive validity was estimated at three different base rates. As regards the DEPI the results showed a large variation in diagnostic performance as the index seemed to have relatively more success in identifying nonpsychotic and unipolar depression than psychotic and bipolar depression. The DEPI did not successfully identify depression among adolescent patients. As regards the SCZI the results more consistently indicated that the index effectively discriminates between psychotic and nonpsychotic patients and the predictive validity of both a positive and negative SCZI was found to be high.     

Focused attention in three-dimensional space

The size of focused attention was assessed within a three-dimensional display. Subjects viewed random-dot stereogram displays in which they responded differentially to vertical and horizontal bars. Adjacent noise elements either were identical to the response target or specified the opposite response. The position of the noise elements was varied in depth according to binocular disparity. Interference by incompatible noise elements decreased with depth separation between the noise elements and response target. In addition, interference was greater for noise elements that were more distant from the observer than from the response target than it was for noise elements that were closer to the observer than to the response target. The implications of these results for a viewer-centered representation of focused attention in depth are discussed.
