Evaluation of a self-instruction package for conducting stimulus preference assessments

Research suggests that inexperienced individuals cannot accurately implement stimulus preference assessments given written instructions alone. Training that includes written instructions supplemented with feedback from a professional with expertise in conducting preference assessments has proven effective; unfortunately, expert-facilitated direct training may not be widely available. In the current study, we used multiple baseline designs to evaluate the efficacy of an antecedent-only self-instructional package to train staff members to implement two methods of stimulus preference assessments. Accuracy was low when participants had access to written instructions alone. When access to enhanced written instructions was provided (i.e., technical jargon was minimized; instructions included pictures, diagrams, and step-by-step examples), inexperienced staff accurately implemented the assessments. Results are discussed in terms of opportunities to disseminate behavior-analytic technologies through self-instruction and print resources.     

A computerized multidimensional measurement of mental workload via handwriting analysis

The goal of this study was to test the effect of mental workload on handwriting behavior and to identify characteristics of low versus high mental workload in handwriting. We hypothesized differences between handwriting under three different load conditions and tried to establish a profile that integrated these indicators. Fifty-six participants wrote three numerical progressions of varying difficulty on a digitizer attached to a computer so that we could evaluate their handwriting behavior. Differences were found in temporal, spatial, and angular velocity handwriting measures, but no significant differences were found for pressure measures. Using data reduction, we identified three clusters of handwriting, two of which differentiated well according to the three mental workload conditions. We concluded that handwriting behavior is affected by mental workload and that each measure provides distinct information, so that they present a comprehensive indicator of mental workload.     

The Effect of Rehabilitation on Positive Interpretations of Illness

Postoperative patients received one of the three, alternative pain-management treatments: patient-controlled analgesia (PCA); perceived PCA (PPCA without actual control) and continuous intravenous infusion of analgesics (CII). Pain reports, morphine consumption and satisfaction of the groups were compared, and influences of individual differences in preferences for control and trait anxiety were tested. The main findings were: (1) PCA patients consumed less morphine and reported more pain and somewhat higher satisfaction; (2) PPCA patients were intermediate between the other two groups in pain reports and morphine consumption and lowest in satisfaction and (3) individual differences did not moderate the effects of PCA. The findings were interpreted as indicating that the main effect of PCA is increased pain tolerance, and that a bio-psycho-social framework is most appropriate to explain these effects.     

Hostility,oral contraceptive use,and cardiovascular reactivity in women

Abstract

Hostility, task instructions, social desirability and cardiovascular reactivity were investigated in a exploratory study of 70 female college students and employees. Women were administered the Videotaped Clinical Interview (VC1), the Marlowe-Crowne Social Desirability Scale (MC), the Cook-Medley Hostility Scale (CM), the Buss-Durkee Hostility Index (BD) and the Personal Attributes Questionnaire (PAQ) before undergoing a stressful discussion. Oral contraceptive users had significantly higher DBP at baseline. Based on PAQ scores, women were given instructions for the discussion task consistent or inconsistent with their gender-relevant styles. Instruction type predicted heart rate changes, and interacted with hostility to predict DBP reactivity. Interview-based hostility (VCI-H) was associated with increased DBP during the discussion task, as was being high hostile (low MC/high VCI-H). The CM and the BD had less association with heart rate and blood pressure changes. Oral contraceptive (OC) use was associated with higher SBP reactivity under stress, with highest SBP increases in the OC users concerned with social desirability. The complex interaction between trait dimensions like hostility, social desirability, and oral contraceptive use requires further investigation.     

La Psicología en la escritura: una visión general

Resumen

En este trabajo, tras una breve introducción en la que se considera la naturaleza e importancia de la escritura, se exponen las ideas generales sobre el estudio de su desarrollo, tanto desde un punto de vista histórico como ontogenético. Seguidamente, se propone una clasificación de los campos de estudio psicológico de la escritura. Por último, se expone un posible marco integrador del área de estudio de la escritura desde un punto de vista cognitivo.     

Emotional time distortions: The fundamental role of arousal

An emotion-based lengthening effect on the perception of durations of emotional pictures has been assumed to result from an arousal-based mechanism, involving the activation of an internal clock system. The aim of this study was to systematically examine the arousal effect on time perception when different discrete emotions were considered. The participants were asked to verbally estimate the duration of emotional pictures from the International Affective Picture System (IAPS). The pictures varied either in arousal level, i.e., high/low-arousal, for the same discrete emotion (disgust or sadness) or in the depicted emotion, e.g., disgust/fear for pictures matched for arousal (high-arousal). The results systematically revealed a lengthening effect on the perception of the duration of the emotional compared to the neutral pictures and indicated that the magnitude of this effect increased with arousal level. Nevertheless, variations in time perception were observed for one and the same arousal level, with the duration of disgust-inducing pictures (e.g., body mutilation) being judged longer than that of fear-inducing pictures (e.g., snake). These results suggest that arousal is a fundamental mechanism mediating the effect of emotion on time perception. However, the effect cannot be reduced to arousal, since the impact of the content of pictures also plays a critical role.     

Low-Cut Shirts and High-Heeled Shoes: Increased Sexualization Across Time in Magazine Depictions of Girls

Theory and past research predict an increase in the sexualization of girls in United States culture. We used content analysis to examine change in the number of sexualizing characteristics (e.g., low cut shirts, high-heeled shoes) and childlike characteristics (e.g., polka-dot print, Mary-Jane style shoes) present in depictions of girls across time in the magazines Seventeen (N?=?1649 images from issues in selected issues from 1971 through 2011) and Girls’ Life (N?=?763 images from selected issues from 1994 to 2011). One-way ANOVAS revealed increases in the total number of sexualizing characteristics across time in both magazines. In particular, depictions of low-cut tops and tight fitting clothing increased in both magazines. There was also a decrease in the number of childlike characteristics in Girls’ Life across time. Possible reasons for increased sexualization as well as possible consequences are discussed.     

Coping style in predicting posttraumatic stress disorder among Israeli students

Abstract

Two possible motives for sensation seeking behavior, escape from self-awareness and compensatory self-regulation, were investigated in two studies. In Study I a questionnaire was developed to identify the putative escape and compensation motives suspected to contribute to sensation seeking behaviors. In Study II the factor structure of this new measure, called the Risk and Excitement Inventory (REI), was cross-validated using confirmatory factor analysis, and construct validity was examined. Together these studies suggest that the REI comprises two reliable factors, compensation and escape from self-awareness. Study II showed that these factors have a reasonable degree of construct validity. Limits of the measure and the model are discussed, and suggestions are offered for future research.     

Heterogeneity of auditory verbal working memory in schizophrenia

The heterogeneity of schizophrenia remains an obstacle for understanding its pathophysiology. Studies using a tone discrimination screening test to classify patients have found evidence for 2 subgroups having either a specific deficit in verbal working memory (WM) or deficits in both verbal and nonverbal memory. This study aimed to (a) replicate in larger samples differences between these subgroups in auditory verbal WM; (b) evaluate their performance on tests of explicit memory and sustained attention; (c) determine the relation of verbal WM deficits to auditory hallucinations and other symptoms; and (d) examine medication effects. The verbal WM and tone discrimination performance did not differ between medicated (n = 45) and unmedicated (n = 38) patients. Patients with schizophrenia who passed the tone screening test (discriminators; n = 60) were compared with those who did not (nondiscriminators; n = 23) and healthy controls (n = 47). The discriminator subgroup showed poorer verbal WM than did controls and a deficit in verbal but not visual memory on the Wechsler Memory Scale-Revised (Wechsler, 1987), whereas the nondiscriminator subgroup showed overall poorer performance on both verbal and nonverbal tests and a marked deficit in sustained attention. Verbal WM deficits in discriminators were correlated with auditory hallucinations but not with negative symptoms. The results are consistent with a verbal memory deficit in a subgroup of schizophrenia having intact auditory perception, which may stem from dysfunction of language-related cortical regions, and a more generalized cognitive deficit in a subgroup having auditory perceptual and attentional dysfunction.     

Affective and Behavioral Changes Following Exposure to Traumatic Events: the Moderating Effect of Religiosity on Avoidance Behavior Among Students Studying Under a High Level of Terror Event Exposure

The goals of this study were to examine the development of affective and behavioral changes following exposure to traumatic events among Israeli students studying under a high level of terror event exposure and to assess the effects of religiosity on those changes development. A questionnaire was administered to 770 students in the Ariel University Center in Judea and Samaria. Higher levels of terror exposure were associated with higher levels of avoidance behavior, subjective feelings of insecurity, and emotional distress. Higher religiosity moderated avoidance behavior, even when controlling for the level of objective exposure to terror events exposure, but had no influence on subjective sense of insecurity, or the level of emotional distress. These findings suggest that religiosity moderates behavioral changes development after traumatic event exposure mainly by reducing avoidance behavior.
