Testing the Mental Model Theory of Propositional Reasoning

Johnson-Laird, Byrne, and Schaeken (1992) present a theory of propositional reasoning by mental models. The present study provides a comprehensive test of the predictions of that theory for the difficulty of simple disjunctive and conditional inferences. The results are largely consistent with the complex pattern of predictions. They are discussed in the light of recently proposed modifications of the original theory.     

Concerns of Older Veteran Callers to the Veterans Crisis Line

When the Veterans Crisis Line (VCL) was implemented, it was uncertain if veterans, and particularly older male veterans, would utilize the service. We examined VCL use by a growing group of veterans at increased risk for suicide: those aged 60 and older. Real‐time clinical data were gathered from a weekly random sampling of calls. Approximately 25% of calls were from veterans aged 60 or older; over 80% reported benefit from the call. Several significant differences in presenting concerns between older and younger callers were found. Targeted outreach to encourage older veterans to use the VCL is suggested.
