Complexity of visual icons studied via signal detection theory

Two investigations on how humans perceive information from visually rendered complex objects, such as military icons (glyphs) were conducted. A signal detection theory framework was employed to evaluate the sensitivity and specificity of human subject performance. The 6 adults tested showed that as complexity increased, their accuracy in performance decreased. Study 1 showed that complex dimensions (features) could not be assigned arbitrarily. Study 2 developed a rank ordering for features of an iconic object.     

THE EFFECTS OF SELF-MONITORING AND SUPERVISOR FEEDBACK ON STAFF PERFORMANCE IN A RESIDENTIAL SETTING

We evaluated the effects of a self-monitoring procedure to increase staff on-task behavior and adherence to scheduled activities. Self-monitoring involved the use of activity cards that staff members completed and carried with them to assist in determining the activities for which they were responsible at any given time. Increases in both on-schedule and on-task behavior resulted. Supervisor feedback was subsequently added because some staff members did not maintain consistently high levels of performance. Generalization data indicated that staff members implemented the procedure during evening hours without specific programming. The advantages and limitations of using a self-monitoring procedure for improving performance of staff members in residential settings are discussed.     

Model-theoretic semantics and revenge paradoxes

Philosophical Studies - Revenge arguments purport to show that any proposed solution to the semantic paradoxes generates new paradoxes that prove that solution to be inadequate. In this paper, I...     

The Contingencies of Interpersonal Acceptance: When Romantic Relationships Function as a Self-Affirmational Resource

Existing research suggests that people with high, but not low, self-esteem use their dating partners' love and acceptance as a resource for self-affirmation when faced with personal shortcomings. The present research examines the role that perceived contingencies of acceptance play in mediating these effects. In Experiment 1, we activated either conditional or unconditional working models and then gave experimental participants failure feedback on an intelligence test. In Experiment 2, we activated thoughts of rejection (or control thoughts) and then gave experimental participants feedback suggesting that their romantic partners would discover their secret sides. Experiment 1 revealed that low and high self-esteem women both embellished their partners' love and acceptance to compensate for self-doubt when the unconditional audience was primed. When rejection was primed in Experiment 2, however, high self-esteem men reacted to the self-threat by doubting their partners' love. These findings suggest that people with low self-esteem may not typically use their relationships to self-affirm because contingencies linking failure to rejection and acceptance to success are chronically accessible in their interpersonal schemas.     

Complex messages regarding a thin ideal appearing in teenage girls’ magazines from 1956 to 2005

Seventeen and YM were assessed from 1956 through 2005 (n = 312) to examine changes in the messages about thinness sent to teenage women. Trends were analyzed through an investigation of written, internal content focused on dieting, exercise, or both, while cover models were examined to explore fluctuations in body size. Pearson's Product correlations and weighted-least squares linear regression models were used to demonstrate changes over time. The frequency of written content related to exercise and combined plans increased in Seventeen, while a curvilinear relationship between time and content relating to dieting appeared. YM showed a linear increase in content related to dieting, exercise, and combined plans. Average cover model body size increased over time in YM while demonstrating no significant changes in Seventeen. Overall, more written messages about dieting and exercise appeared in teen's magazines in 2005 than before while the average cover model body size increased.     

Systemic-Oriented Psychological Counselling for Caregivers of People with Severe Brain Injury: Reflections on a Clinical Case

Severe brain injuries can have dramatic consequences on family life, often changing rules and routines and fostering intense and prolonged caregiving duties. People affected by the injuries have to face relevant restrictions in their activities and a loss of independence. Thus, primary caregivers are often involved in their assistance, which can entail the help for self-care, movements and many activities of daily living. Furthermore, cognitive and behavioural symptoms can complicate communication, disrupt previous relationships and put an additional strain on all family members. Indeed, caregiving relationships take place in wider familial and societal contexts and are obviously influenced by previous characteristic of such relationships, as they were before the onset of the pathological condition. Therefore, a thorough examination of typical emotions, feelings and thoughts that can emerge during caregiving must be paralleled by an ecological and developmental perspective, in order to appraise the complexity of these cases and provide effective interventions. The present work aims to address such topics taking inspiration from a clinical case.     

Factor analysis of the Dutch-language version of the MCMI-III

We analyzed the factor structure of the Dutch-language version of the MCMI-III (Millon, Millon, Davis, & Grossman, 2006) using exploratory factor analysis on data obtained from a heterogeneous White sample (n = 1,210). We identified 4 factors: General Maladjustment, Aggression/Social Deviance, Paranoid/Delusional Thinking, and Emotional Instability/Detachment. This structure was invariant across scale composition (linear dependent vs. independent scales), factor analytic method (principal factor vs. principal component solutions), and sample characteristics (gender 'male-female' and setting 'clinical-forensic.' Studies that have used previous MCMI (Millon, 1969/1983b) versions have also found 4 similar factors, whereas studies that have used the American version of the MCMI-III have only found 3 factors. However, differences between the Dutch and American version were completely determined by factor analytic decisions. The factor structure of the MCMI-III appeared to be cross-culturally invariant.
