Prior experience modifies acquisition trajectories via response–strategy sampling

Animal Cognition - Few studies have considered how signal detection parameters evolve during acquisition periods. We addressed this gap by training mice with differential prior experience in a...     

Measuring associations between social anxiety and use of different types of social media using the Swedish Social Anxiety Scale for Social Media Users: A psychometric evaluation and cross-sectional study

Research on the association between social anxiety and social media usage remains inconclusive: despite the preference for computer-mediated communication there is currently no clear empirical support for social anxiety being associated with longer duration of social media use. Self-report measures for social anxiety that are adapted for the context of social media could facilitate further research. The current study aimed to develop a Swedish version of the recently developed Social Anxiety Scale for Social Media Users (SAS-SMU), evaluate its psychometric properties, and explore associations between different uses of social media and social anxiety. Three factors were retained for SAS-SMU with excellent internal consistency. SAS-SMU evidenced convergent validity with measures of social anxiety, negative convergent validity with satisfaction with life, and divergent validity with measures of obsessive-compulsive disorder, depression and generalized anxiety disorder. Results indicated that higher levels of social anxiety were associated with passive and active use as well as longer duration of social media use in general, which is at odds with a previous study where passive use remained the only significant predictor for social anxiety.     

Using Item Response Theory to Develop a 60-Item Representation of the NEO PI–R Using the International Personality Item Pool: Development of the IPIP–NEO–60

Given advantages of freely available and modifiable measures, an increase in the use of measures developed from the International Personality Item Pool (IPIP), including the 300-item representation of the Revised NEO Personality Inventory (NEO PI–R; Costa &; McCrae, 1992a Costa, P., &; McCrae, R. (1992a). The five-factor model of personality and its relevance to personality disorders. Journal of Personality Disorders, 6, 343–359.[Crossref], [Web of Science ®] , [Google Scholar]) has occurred. The focus of this study was to use item response theory to develop a 60-item, IPIP-based measure of the Five-Factor Model (FFM) that provides equal representation of the FFM facets and to test the reliability and convergent and criterion validity of this measure compared to the NEO Five Factor Inventory (NEO-FFI). In an undergraduate sample (n = 359), scores from the NEO-FFI and IPIP–NEO–60 demonstrated good reliability and convergent validity with the NEO PI–R and IPIP–NEO–300. Additionally, across criterion variables in the undergraduate sample as well as a community-based sample (n = 757), the NEO-FFI and IPIP–NEO–60 demonstrated similar nomological networks across a wide range of external variables (r_ICC = .96). Finally, as expected, in an MTurk sample the IPIP–NEO–60 demonstrated advantages over the Big Five Inventory–2 (Soto &; John, 2017 Soto, C. J., &; John, O. P. (2017). The next Big Five Inventory (BFI–2): Developing and assessing a hierarchical model with 15 facets to enhance bandwidth, fidelity, and predictive power. Journal of Personality and Social Psychology, 113, 117–143.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]; n = 342) with regard to the Agreeableness domain content. The results suggest strong reliability and validity of the IPIP–NEO–60 scores.     

An Examination of the Connections Between Eating Disorder Symptoms,Perceived Burdensomeness,Thwarted Belongingness,and Suicide Risk Among Undergraduate Students

Suicide attempts and premature mortality due to suicide are elevated in people with eating disorders. Informed by the interpersonal theory of suicide, two studies examined the role of perceived burdensomeness and thwarted belongingness in explaining the association between eating disorder symptoms and suicide risk. Results indicated that various eating disorder symptoms had an indirect effect on suicide risk through perceived burdensomeness and thwarted belongingness. Targeting perceived burdensomeness and thwarted belongingness may be useful for decreasing suicide risk among undergraduates with eating disorder symptoms.     

Perceived Racism and Suicide Ideation: Mediating Role of Depression but Moderating Role of Religiosity among African American Adults

Suicide is a public health problem for African Americans who are young and of working age. The purpose of this study was to examine mediated and moderated effects of perceived racism on suicide ideation in a community sample of 236 African American men and women. Measures of suicide ideation, depression symptoms, intrinsic/extrinsic religiosity, and perceived racism were administered. Perceived racial discrimination was directly and indirectly associated with suicide ideation. For participants who reported low levels of extrinsic religiosity, the mediated effect of perceived racism (via depression symptoms) was significant. These findings provide some insight into suicide vulnerability for specific subgroups of African Americans.     

Teaching Psychiatric Patients: A Psychoanalytic Study

This paper attempts to describe some of the challenges of teaching psychiatric patients within a hospital environment. It uses post-Kleinian ideas to look at the unconscious processes at work within the learning/teaching dynamic and observes the psychotic mind's unique approach to learning. The central hypothesis of the paper is that psychoanalytic reflection of educational processes within a psychiatric institution is of clear benefit to both teacher and learner, and can also forestall several of the more problematic or even harmful outcomes of the increasing trend to ‘educate’ the patient.
