A job with a future? Delay discounting, magnitude effects, and domain independence of utility for career decisions

Decision-makers are often faced with inter-temporal choices in which they are required to choose between options that differ in both value of and delay to outcomes. In this study, assumptions of Discounted Utility Theory (DU) were tested within inter-temporal career choices. According to DU, the same discount rate should be applied regardless of the amount of delay and magnitude of the outcome. In addition, DU predicts that, for economic substitutes, the same discount rate should be applied to both commodities. Contrary to assumptions of DU, but consistent with a hyperbolic discounting model, graduating college students’ job choices reflected non-constant discount rates (i.e., Delay Effect) for future salary and preferred tasks. In addition, these students exhibited lower discount rates for salary and percentage of preferred tasks (i.e., Magnitude Effect). Finally, the two were not found to be economic substitutes as there was a low correlation between discount rate for salary and percentage of preferred tasks (i.e., Domain Independence). Implications for employee recruitment and human resource management are discussed.     

Optimizing the scientific study of suicide with open and transparent research practices

Suicide research is vitally important, yet—like psychology research more broadly—faces methodological challenges. In recent years, researchers have raised concerns about standard practices in psychological research, concerns that apply to suicide research and raise questions about its robustness and validity. In the present paper, we review these concerns and the corresponding solutions put forth by the “open science” community. These include using open science platforms, pre‐registering studies, ensuring reproducible analyses, using high‐powered studies, ensuring open access to research materials and products, and conducting replication studies. We build upon existing guides, address specific obstacles faced by suicide researchers, and offer a clear set of recommended practices for suicide researchers. In particular, we consider challenges that suicide researchers may face in seeking to adopt “open science” practices (e.g., prioritizing large samples) and suggest possible strategies that the field may use in order to ensure robust and transparent research, despite these challenges.     

Artificial intelligence for the measurement of vocal stereotypy

Both researchers and practitioners often rely on direct observation to measure and monitor behavior. When these behaviors are too complex or numerous to be measured in vivo, relying on direct observation using human observers increases the amount of resources required to conduct research and to monitor the effects of interventions in practice. To address this issue, we conducted a proof of concept examining whether artificial intelligence could measure vocal stereotypy in individuals with autism. More specifically, we used an artificial neural network with over 1,500 minutes of audio data from 8 different individuals to train and test models to measure vocal stereotypy. Our results showed that the artificial neural network performed adequately (i.e., session-by-session correlation near or above .80 with a human observer) in measuring engagement in vocal stereotypy for 6 of 8 participants. Additional research is needed to further improve the generalizability of the approach.     

A case of subcortical dementia due to sarcoidosis of the hypothalamus and fornices

A patient with sarcoidosis involving predominantly the hypothalamus and fornices was evaluated for dementia. He showed a relative sparing of fund of knowledge and orientation. Memory skills, particularly short-term memory, were severely impaired. Behavioral changes included apathy and a lack of spontaneity. Insight was relatively preserved. The pattern of his deficits showed some similarities to the pattern reported in patients with Huntington's disease and was different from that described in Alzheimer's disease. The dementia caused by subcortical pathology may differ in important respects from that caused by diffuse cortical dysfunction.
