Working memory for item and temporal information in younger and older adults

Two experiments examined age differences in mechanisms hypothesized to affect activation of item and temporal information in working memory. Activation levels were inferred from the ability to reject n-back lures matching items in different temporal positions. Information with the least decay had a performance advantage over less recent information, but was susceptible to the same temporal context errors found in all adjacent-to-target lure positions. Lures most distant from the current item showed a performance rebound. The pattern of increased magnitudes of age effects at adjacent-to-target positions indicated a reduction in older adults' working memory for temporal context information above and beyond item memory declines. Results overall support the emphasis on context information as a critical factor in working memory and cognitive aging.     

A Unified Nonparametric IRT Model for <Emphasis Type="Italic">d</Emphasis>-Dimensional Psychological Test Data (<Emphasis Type="Italic">d</Emphasis>-ISOP)

The (univariate) isotonic psychometric (ISOP) model (Scheiblechner, 1995) is a nonparametric IRT model for dichotomous and polytomous (rating scale) psychological test data. A weak subject independence axiom W1 postulates that the subjects are ordered in the same way except for ties (i.e., similarly or isotonically) by all items of a psychological test. A weak item independence axiom W2 postulates that the order of the items is similar for all subjects. Local independence (LI or W3) is assumed in all models. With these axioms, sample-free unidimensional ordinal measurements of items and subjects become feasible. A cancellation axiom (Co) gives, as a result, the additive isotonic psychometric (ADISOP) model and interval scales for subjects and items, and an independence axiom (W4) gives the completely additive isotonic psychometric (CADISOP) model with an interval scale for the response variable (Scheiblechner, 1999). The d-ISOP, d-ADISOP, and d-CADISOP models are generalizations to d-dimensional dependent variables (e.g., speed and accuracy of response).

Self-Presentation of Beliefs About Gender Discrimination and Feminism

This study examined whether college students' expressed beliefs about gender discrimination and feminism are due to concerns about self-presentation rather than an accurate reflection of their beliefs. Fifty-eight women and 45 men (82% Caucasian) completed scales measuring their beliefs about gender discrimination and feminism and responded to scenarios about hypothetical court cases involving discrimination. Participants were told their personal views would be either shared publicly or remain private during a small group discussion. Results showed that men expressed more belief in gender discrimination and feminism in the public groups compared to men in private groups and women. Responses to hypothetical court cases also showed some evidence of self-presentation. Implications for changes in self-identity and behavior toward incidents of gender discrimination are discussed.

Developing Spiritual Competencies in Counseling: A Guide for Supervisors

The recently established competencies for addressing spiritual and religious issues in counseling (Association of Spiritual, Ethical, and Religious Values in Counseling, 2009 ) provide guidelines for counselors to implement in conjunction with evidence‐based counseling practices. These spiritual competencies complement the ethics code established by the American Counseling Association ( 2014 ) in promoting increased cross‐cultural sensitivity and proficiency in counseling. Supervisory tools that promote the ethical and spiritual development of counseling trainees are identified and described.
