Manipulating establishing operations to verify and establish stimulus control during mand training

Acquisition of verbal behavior is a major goal of interventions for children with developmental disabilities. We evaluated the effectiveness of manipulation of an establishing operation for functional discriminated mands. Four individuals with developmental disabilities participated in a training procedure designed to teach two separate mands for two separate preferred items. Participants were taught to mand using picture cards. Following training, the manipulation of the establishing operation was used to assess and establish discriminated manding. This manipulation involved providing free access to one of the preferred items, such that there should be no motivation to ask for it, while motivation to ask for the other item remained in place. Three of the 4 participants acquired discriminated manding using topographically similar responses (picture cards). One participant did not acquire a discriminated mand until topographically distinct mands were taught (vocal and picture card). Results suggest that discrimination training is not necessarily sufficient to teach discriminated manding when more than one picture card showing preferred items is used. In addition, manipulation of the establishing operation served as an appropriate assessment tool for the verification of discriminated manding as well as a possible training tool to establish discriminated manding.     

The virtual haptic display: A device for exploring 2-D virtual shapes in the tactile modality

In order to understand better the processes involved in the perception of shape through touch, someelement of control is required over the nature of the shape presented to the hand and the presentation timing. To that end, we have developed a cost-effective, computer-controlled apparatus for presenting haptic stimuli using active touch, known as a virtual haptic display (VHD). The operational principle behind this device is that it translates black and white visual images into topographic, 2-D taxel (tactile pixel) arrays, along the same principle using in Braille letters. These taxels are either elevated or depressed at any one time representing white and black pixel colors of the visual image, respectively. To feel the taxels, the participant places their fingers onto a carriage which can be moved over the surface of the device to reveal a virtual shape. We conducted two experiments and the results show that untrained participants are able to recognize different, simple and complex, shapes using this apparatus. The VHD apparatus is therefore ideal at presenting 2-Dshapes through touch alone. Moreover,this device and its supporting software can also be used for presenting computer-controlled stimuli in cross-modal experiments.     

The Costs of Silencing the Self and Divided Self in the Context of Physical Abuse,Racial/Ethnic Identity,and Medication Adherence in Women Living with HIV

Racial/ethnic minority status and physical abuse history are risk factors for higher mortality rates and lower adherence to antiretroviral therapy (ART) in women living with HIV (WLWH) in the United States. The current study tested the hypotheses that minority status and physical abuse history might lead women to silence the self (minimize and hide thoughts and feelings in order to avoid relational conflict, loss, and/or abuse) as measured by the Silencing the Self Scale (STSS), and that STSS might mediate and moderate relationships of physical abuse and racial/ethnic minority status with ART adherence. Divided Self (DS; acting in ways inconsistent with inner thoughts and feelings), an STSS subscale, was targeted for study along with the total STSS score. Participants were 513 women from the U.S. Women’s Interagency HIV Study (M_age?=?46; 387, 75%, Black; 66, 13%, Hispanic; 60, 12%, White). Multiple logistic regressions indicated that across all racial/ethnic groups, physical abuse history related to higher DS and lower adherence. DS significantly mediated relationships between abuse and adherence. Compared to White women, Black women demonstrated worse ART adherence, but had lower total STSS. Racial/ethnic minority women and women with a physical abuse history who had higher DS had lower adherence than other groups. Results indicate that being a racial/ethnic minority or having a history of physical abuse may increase vulnerability to the deleterious effects of DS on ART adherence, findings that can help inform interventions to decrease health disparities in WLWH.

     

Are we assessing guilt correctly? An investigation of the psychometric properties of a prominent guilt measure

The construct of trait guilt has played an important role in psychological theory across many fields of psychology (e.g., as a diagnostic criterion in clinical psychology, as an individual difference in personality psychology, and as a motivational antecedent or emotional moderator in social and organizational psychology); however, the measurement of guilt has received comparatively limited attention in the literature. Specifically, existing measures have limited factor analytic support, limited evidence of convergent validity among the measures, and although the theoretical distinction between guilt and shame is well established, there is limited empirical support for the discriminant validity of these constructs as they are currently measured. The current study investigates the psychometric properties of the most commonly used measure of guilt, the Test of Self-Conscious Affect-3 (TOSCA-3; in: Tangney, The Test of Self Conscious Affect-3. George Mason University, Fairfax, 2000), in order to (a) examine the factor structure of the measure, (b) estimate the convergent validity of the measure with other guilt assessment instruments, and (c) examine the discriminant validity of guilt and shame. Results involving a sample of 1760 participants provide support for a multitrait-multimethod model and the discriminant validity of guilt and shame. However, limited evidence of convergent validity between the TOSCA-3 and the Revised Mosher Guilt Inventory (φ?=?.21) and the Trauma-Related Guilt Inventory (φ?=?.10) suggested the TOSCA-3 is not assessing guilt in the same manner as more contextualized measures of guilt, highlighting the importance of measurement choice for guilt researchers. Implications for the measurement of trait guilt are discussed.

     

Six Constructs to Define Rorschach M: A Response

The experimental validity of six constructs, conceptualized to account for Rorschach M, was suggested by (a) step-wise regression analysis on scores from task definitions of each construct and M scores for 45 female subjects, and (b) task correlations with their M scores. Fantasy, time estimation, and intelligence were significantly related to M. Inadequacies of task definitions or initial conceptualization were suggested by the correlational data.
